Battery for Asus A32-N62

Because the keyboard is weighted (the battery takes care of that), it shifts the centre of gravity back, so the hallmark "woah it's going to tip backwards" that characterises all prior Surfaces doesn't apply here.That said, I suspect that the Surface ("the clipboard" in Microsoft's language) will stay docked in the keyboard almost all of the time – coming out only for movies and TV. Or in my case, for the kids to demand Fresh Paint. (Note: if you think I'm opinionated wait 'til you hear my kids' views on the design changes to Fresh Paint between Windows 8.1 and Windows 10. You'll really get an earful.)The keyboard itself is absolutely stellar for typing. The keys have a deep and firm travel, and bounce right back at you, a little like the famously clacky IBM Model M keyboards used to do. But quieter, obviously – it doesn't sound like a hundred rat traps going off at once. The Surface Book's keyboard has a key for the Context menu and weirdly, an Alt Graph (Alt Gr) key, a throwback to pre-GUI IBM PCs.The keyboard houses its own Mini Display port, an SD card slot, and two USB 3.0 ports. The keyboard is where you charge this critter, although both keyboard and "clipboard" have their own batteries. More of that in a moment.Like the display it hosts, the keyboard is made of a magnesium alloy that feels slightly other worldly. It's like a metal, but is too light to be a metal (it really is a metal, though). My only grumbles with it are that there's no island for a set of Home/End/PgUp/PgDn keys. Microsoft reserves the two brightness keys for dimming the backlit keyboard – you have to use Fn + Delete and Fn + Backspace to control the screen brightness.



As with Google and Nexus, Microsoft gets to control the entire experience – no OEM crapware. Except you do get Flipboard and Candy Crush Soda Saga, and possibly some other stuff you didn't want.
Who has the power?
Microsoft tells me that the Surface Book should last for 12 hours. And here it gets complicated, because it's very hard to tell. Officially, the Surface Book discharges the capacity of the base-keyboard part first, then only when the base is low, taps into the display battery's power reservoir. Charging, it's the other way around, mostly: it charges the display part first and the base a little bit too. The reality is that based on the instrumentation, it's hard to tell. The Surface Book takes its time giving you a report on how much time you've got left.One factor is that when clipped together, the Nvidia card is in use, which saps more power. Much more so, obviously, if you're gaming. I found the power reporting let things down generally. Not only is it reluctant to give you an estimate, but the estimates vary wildly.



The second screenshot is taken a few minutes after the first, with no change in workload or screen brightness.Surface wouldn't be Surface without a few glitches. The first time I used the Eject button, it released the Display portion with a satisfying click. (Which is actually an audio file). And it worked the second time. But it hasn't worked once since. Infuriatingly, Surface Book wouldn't tell you what was causing it to maintain its Rottweiler grip on the display, the red LED merely indicating that you shouldn't. You can do a Vulcan nerve pinch to reset everything but it requires a reboot.Here's another, something the latest version of Photoshop caught. The Nvidia card actually has 1GB of RAM, but Photoshop is confused.
Performance was excellent – which is to say, smooth sailing until stalled by Windows 10's randomness. Pages load incredibly fast but it just isn't as smooth as native code should be, with inexplicable, second-long freezes. (Sometimes several seconds.)This is the top-of-the-range model, but newer Intel chips are now available because it's taken so long for a UK Surface Book to... uh, Surface.


I liked my time with the Surface Book, and grew to like it more as I got used to the heft and quirks. But with top performance and outstanding features in convertibles half the price, you really are paying a premium for Surface exclusivity that might make Apple blush.An attendee at the KubeCon Kubernetes conference in London has exposed a serious lack of network security in the hotel where he was staying.Matthew Garrett, a security researcher for CoreOS and a board member of the Free Software Foundation, was in his hotel when he noticed the establishment had replaced the light switches with little Android pads to control lighting and other room functions.Being of a technical mien, he borrowed a couple of USB Ethernet adapters and set up a transparent bridge between the tablet and the wall so that his laptop could analyse the traffic between the two.Using popular protocol analyzer Wireshark he discovered that the tablet was running the Modbus control protocols, which don't use authentication controls, and after finding the IP address the tablet was using, Garrett was able to control his room's controls.


"Then I noticed something. My room number is 714. The IP address I was communicating with was 172.16.207.14. They wouldn't, would they? I mean yes obviously they would," he wrote in a blog post."It's basically as bad as it could be – once I'd figured out the gateway, I could access the control systems on every floor and query other rooms to figure out whether the lights were on or not, which strongly implies that I could control them as well."It might seem that this isn't too serious. Jokers could wake people up by turning their lights on and off in the middle of the night perhaps, but a thief could also get an idea of whether a room was occupied by checking the status of its room controls.This isn't the first time something like this has come up. In a 2014 presentation at Black Hat, researcher Jesus Molina, a former chair of the Trusted Computing Group, found he could do the same thing to all the rooms in the St Regis hotel in the Chinese city of Shenzhen.In both cases, neither researcher tried to get into other systems on the hotel network, such as billing or reservations, but given the lamentable state of the control system it's not outside the realm of possibility that some serious damage could be done.



Hotel hacking is something that's coming under increasing scrutiny by researchers and some hotel groups. Back in 2012, another Black Hat presentation showed how easy it was to reprogram electronic door keys in hotels. One hotelier then sued the manufacturer of the keys, claiming his guests had been robbed using the technique. In this article I'm going to talk about the second most important aspect of being an IT manager or engineer. “The second?” I hear you cry. Yes, the second, because the most important aspect is terribly dull and doesn't take 800 words to describe: safety. (And if you think I'm mad, ask yourself whether you'd break down the door of your secure data store to rescue the guy inside in the event of a fire).The second most important aspect, then, is security. And that statement will annoy the hell out of business people (IT systems' purpose is to help them make money), system engineers (their purpose is to keep systems running and reliable), users (they need to be able to do their jobs efficiently and accurately and expect the systems to help them do that), customers (they want the online store to be snappy and deliver their order the same day where possible), … well, pretty much anyone.As we all know, IT is one of those areas that only really gets noticed for its negative aspects. The beancounters see it as a cost centre and want to know why we can't get another year's use from the printers (hey, if they've coped for seven years surely another one won't make a difference).

Battery for Toshiba PA3535U-1BAS

The two closest things to Slack in the open source world are Mattermost and Rocket Chat. Both support all the popular features of Slack including inline code snippets (Rocket Chat even offers code highlighting), inline images, archived searchable conversations, easy sign up, web apps, desktop apps and mobile clients. Rocket Chat also includes support for Markdown, and Mattermost can import Slack user accounts and channel archives to smooth the transition.Where the two differ is in the user interface and in the backend setup (Rocket Chat uses MongoDB behind the scenes, while Mattermost uses PostgreSQL). Mattermost user interface is a bit closer to Slack, while Rocket Chat seems to have taken more inspiration from full-featured IRC clients.Both, however, are self-hosted, which means projects can get most of the advantages of Slack over IRC, but retain control of the open source tools. If the history of web services teaches anything, it's that relying on third-party services for key parts of your development infrastructure is almost guaranteed to fail in the long run.While Mattermost and Rocket Chat, along with services like IRCCloud, which piggybacks on IRC to offer a more Slack-like experience, can fulfil 90 per cent of the Slack experience, none of the them match Slack 100 per cent. Mattermost lacks an Android client (it's in the works), none of them have the amount of third-party integration that Slack offers, and none of them have the install base that Slack claims to enjoy - 1.1 million “daily average users in July last year so it said.


It's the last point that open-sourcers needs to consider. Ubiquitous install trumps everything else. With more and more developers using Slack on small teams at work (as it's intended to be used) it's natural to want to use the same tools for other projects.There is an opportunity here for open source, though. Setting up and using Slack may be simple but extending it is not. If more developers turn to open source alternatives there will be more developers to hack on these alternatives. More momentum means more features, more cool hacks and in the end a more useful product. This is why Apache trumps Microsoft IIS, WordPress thrives while Movable Type is a memory, and Linux is the most wildly deployed operating system on the server.On the other side of the argument, lack of developer interest in alternatives is part of why Dropbox has no real open-source competitor, Google Docs continues to be more popular than open-source options, and Foss offers almost no competition to Skype.Slack may be the best choice now, but investing in open source alternatives like Mattermost or Rocket Chat is the best choice for open source coders in the long term.



VMware's popped out its second update to vSphere 6.0 and addressed a long-time vAdmin gripe by adding a new web interface that doesn't rely on old-school plugins.The new VMware Host Client is an all HTML-5 affair. The new code is derived from a “Fling” VMware posted a few weeks back (Flings are useful-but-unsupported code that VMware suggests vAdmins might want to play with) and has now made it into ESX.It's still no masterpiece of usability – as the illustration at top (or here for those reading our mobile site) attests – but is notable for two reasons. One is that VMware has remained loyal to the ancient Netscape derived NPAPI plugin standard. Moving to HTML 5 does away with that. The second is that vAdmins have often bemoaned the state of the web clients available to them. The new enhancements here will therefore be welcome.The headline feature of the vSphere update is support for 25 G and 50 G ethernet link speeds, handy for obvious reasons.There's also an upgrade to vSphere's VAIO – that's the vSphere APIs for IO Filtering, not a laptop - to better handle all-IPv6 environments.


There's half a dozen security fixes included, none toe-curling, and fixes for the usual range of small problems like “ Hostd randomly stops responding on hosts with 3D acceleration” and “ Unable to perform vMotion with VMs that has two 2TB virtual disks.”AMD's copped a little kick: its Opteron 12xx, 22xx and 82xx series CPUs are no longer supported because they're not on sale so VMware can't be bothered supporting them any more. Wouldn't happen to old Intel kit, we bet.Review I've always wondered what people who pay more than £2,000 for a Windows laptop are thinking when they boot the machine.It's a bit like paying a fortune to gain admission to a secret and exclusive members club, only to discover once you're in, that it's run by the bloke who does the pub quiz on a Tuesday night at your local... and all the bar regulars you thought you'd paid to avoid.


"Oh... hello, Windows. Fancy seeing you here. No, go on, tell me that unfunny story I've heard a hundred times before."Sumptuous and slightly absurd, Microsoft's Surface Book is the most expensive laptop you can get, short of ordering a 24-carat custom gold plated jobbie.Six months after its bombastic unveiling (during which Surface chief Panos Panay looked like he was going to hit someone), it's finally washed up on these shores. And very nice it is too. As you'd expect for £2,249 including VAT (pen included), which is what the top model will set you back. (Or $3,199 in the US.)Sony never had much trouble shifting £2,000 Vaios and Microsoft has cracked it. Redmond claims to have $4.2bn extra cash in the coffers thanks to the Surface line, which is now widely imitated. You could argue (I won't, but you might) that Apple's oversized iPad Pro is Cupertino's response to the Surface – or a hedge against its continuing success.
The Surface Book is a quite different proposition to the Surfaces that have come before it. It's bigger, with a 3200x2000 (267ppi) 13.5-inch display; this beast weighs 3.34lbs or 1.5kg.



And its own lavish custom keyboard, which houses an Nvidia graphics unit, and an extra battery. An Nvidia GPU isn't an option for all Surface Book configurations, but it is in all the i7 configurations, and was in the model reviewed here.The inclusion of a GPU means you can't just yank it out – the software you're running might be using the Nvidia card, so there's a strange little dance where you wait for confirmation that it's OK to remove the Surface from its keyboard.It's the graphics card, a rarity in laptops for years now, that gives it gaming and professional media editing chops. The display itself is dazzling and the sound superb.
Note the orientation of Windows from the photo – that the Surface thinks you're the main user. An obvious use is 1:1 presentations
What gives the Surface Book its distinctive look – the wind blows through when it's closed – is the hinge. The trick here is using a shape memory alloy that can shape and contract. It doesn't fold back flat, which is where the other trick comes in: the machine is reversible. Lift it out, rotate it 180 degrees, and drop it back in. You've got a display tablet with the keyboard still attached. There's a dedicated Eject key for removing it, with an LED that is red if it thinks yanking away the Nvidia GPU will cause the software problems.

Batterie pour Sony VGP-BPS10A

Windows 8 est fin prêt à être commercialisé. Microsoft vient de terminer le développement de son OS et l’a envoyé aux constructeurs de tablettes et ordinateurs portables. Le site Liveside a par ailleurs eu l’excellente idée de compiler quelques captures de la version finale, présentant des applications déjà connues des utilisateurs de la bêta, et d’autres totalement inédites… Pour rappel, Windows 8 sortira le 26 octobre prochain et représente une évolution majeure dans l’environnement Windows de par sa forme tout d’abord mais également son parti pris pour le tout tactile.Vendue 49,67€ sur Amazon.de et sur une poignée d’autres sites, la Stealth Touch Mouse est une souris sans fil et sans boutons, qui ne fait pratiquement aucun bruit. Elle s’aligne sur les souris haut de gamme de Microsoft, Logitech et Apple, sans pour autant exploiter le même filon…


Lorsque l’on dit souris sans boutons, on pense bien entendu au tout tactile, qui a tendance à se généraliser avec la gamme “Touch Mouse ” de Microsoft et quelques produits de Logitech et Apple. Pourtant, la Stealth Touch Mouse n’est pas à proprement parler une souris tactile.L’accessoire est vendu en boutique pour une petite cinquantaine d’euros et est accompagné d’une petite prise USB à introduire dans votre ordinateur portable pour l’installation mais également pour l’utilisation wireless. Très moderne dans son design, la Stealth Touch se dirige facilement puisqu’elle conserve des contrôles très proches d’une souris classique : clic gauche, droit, par une simple pression sur la zone correspondante, scroll vertical exactement au même endroit, et slide pour la présentation d’un document Powerpoint ou PDF. Autrement dit, il ne s’agit pas réellement d’une concurrente aux souris tactiles que nous connaissons mais bel et bien d’une souris dont les boutons auraient tout simplement été remplacés par une surface plane…


Quel intérêt dès lors à se la procurer? Tout d’abord, la souris en question ne fait pratiquement pas de bruit. C’est tout juste si on entend un léger crissement lorsqu’on scrolle verticalement. Ensuite, son design uniforme représente à lui seul une raison de craquer pour cette souris si particulière… Enfin, il faut bien reconnaitre que la Stealth Touch est très agréable à manipuler. Ainsi, on apprécie tout particulièrement la sensation très douce au toucher, et l’absence totale de boutons, qui contribue beaucoup au charme de cet accessoire.Niveau caractéristiques techniques, Manhattan a opté pour une technologie laser, tout comme Apple avec sa Magic Mouse. La Stealth Touch Mouse est par ailleurs aussi bien compatible avec les PC Windows que les Mac, ne nécessite aucun logiciel d’installation et dispose d’une garantie “à vie”. Autant d’arguments qui font de cette souris un accessoire très agréable à utiliser et surtout très simple à prendre en mains.Pour devenir ou rester mythique, il faut savoir mourir. Après avoir conquis les téléspectateurs et internautes, la micro-série de Canal + est disponible gratuitement sur smartphone et tablette.



La micro-série de Canal + – 82 épisodes de deux minutes environ – «Bref» donc, s’est arrêtée il y a peu, moins d’un an après son lancement. Présentée trois fois par semaine en clair sur la chaîne cryptée et accessible via Internet, elle a immédiatement trouvé son public, qui se consolera désormais avec une application pour téléphones portables et tablettes numériques.On y retrouve 39 épisodes. Un aperçu de la vie du personnage joué par Kyan Khojandi, un type normal – c’est à la mode en France –, limite loser. Un type qui peine à monter un meuble Ikea, joue à la console, drague comme un manche et se souvient avec émotion du temps où l’on remontait les cassettes grâce à un stylo. Un type qui raconte son morne quotidien – «J’ai fait une soirée déguisée», «J’ai pris le métro», «J’ai passé un coup de fil» – avec la finesse et l’humour des grands observateurs. Un type qui parle vite et enchaîne les propos rapportés: «Elle m’a dit», «Je lui ai dit», «Elle m’a dit». Bref, un type attachant. Mi-juillet pourtant, les créateurs de la série, Kyan Khojandi, Bruno Muschio et Harry Tordjman ont annoncé la fin, craignant de «faire la saison de trop». «Notre leitmotiv depuis le début était de surprendre […] et nous avons maintenant l’intime conviction que le dessin est fini et qu’il serait dommage de colorier la table.»


L’application permet aussi de se glisser dans l’iPhone du personnage. Défilent ses photos: son père, sa «nana», son «plan cul», ses bricolages réalisés en bouchons de champagne. Ses messages: insultes de Marla, excuses de son colocataire ou tentative d’approche d’une fille post-it. Son répertoire même, que nous avons testé; la messagerie Orange de son copain Baptiste déborde, le téléphone de sa «maman» sonne une dizaine de coups avant de bifurquer sur un répondeur. Quelques répliques-cultes encore et un catalogue des publicités croisées au fil des épisodes. Bref, une chouette application.La petite 3DS de Nintendo s’offre un lifting, histoire de booster un peu ses ventes. La firme japonaise vient en effet de sortir en Europe la 3DS XL, une version extra-large de sa console portable, offrant un écran 90% plus grand que l’original.Depuis le 28 juillet, ceux qui souhaitaient mettre la main sur la dernière portable de Nintendo auront sans doute encore plus de mal à ne pas craquer pour la petite dernière de Big N. La firme japonaise remplace en effet sa 3DS par une console disposant d’un écran 90% plus grand que l’original, vendue à 199€. Mais tout cela est-il suffisant pour nous faire craquer? Petit état des lieux…



Sortie en mars 2011, la 3DS avait connu quelques critiques du public, principalement liées à la 3D et à l’écran de taille réduite de l’appareil. Bien décidé à rectifier le principal défaut de sa machine, qui a tout comme la PS Vita de Sony de plus en plus de mal à justifier son achat face aux jeux sur smartphones, Nintendo avait pris la décision de sortir cette année une version XL de sa petite console portable, qui passe pour l’occasion à du 4,88″. En pratique, cela représente une augmentation de 90% de la taille de l’écran, et de seulement 46% de la taille de la machine. Plus optimisée, la machine dispose d’un design légèrement épuré et surtout d’une meilleure autonomie – 6h30 contre 5h précédemment.Côté petits bonus, on retrouve également une carte SD de 4 Go, plutôt que 2 Go, témoignant du succès de l’eShop de Nintendo, désormais entré dans les moeurs. Davantage orientée téléchargement que sa grande soeur, la 3DS XL n’apporte finalement guère de véritable révolution par rapport à son ainée, mais quelques petites modifications qui font toute la différence. L’écran XL est beaucoup plus agréable à utiliser et offre une meilleure visibilité, la console dispose d’une meilleure autonomie et l’acheteur en a davantage pour son argent qu’avec la 3DS. De plus, la console dispose désormais d’un catalogue de jeux beaucoup plus riche qu’à ses débuts, ce qui devrait finir de convaincre les quelques acheteurs dubitatifs.

Battery for Apple MacBook Pro 13

The Seagate blog says there is an Archive HDD inside the casing, which means it uses shingled magnetic recording, has six platters, reads and writes at 190/150MB/sec respectively, and spins at 5,900rpm. Obviously it is meant as a backup drive for notebook and desktop users.The drive has a natty shiny aluminium wrap-around, six-ribbed side look, one rib for each platter, with textured dark grey top and bottom surfaces. The thing can lay flat or be placed vertically. Its casing was designed by Huge-Design, a firm which has done product designs for GoPro, HP, and Nike.Customers get Seagate Dashboard software, with either one-click on-demand or customisable, scheduled backups, plus 200GB of Microsoft OneDrive cloud storage and Lyve software compatibility, so users can back up, access and share files from any device/location.The Innov8 drive will be available in April for $349 (US MSRP) through Seagate.com, Amazon and other resellers. Get a datasheet here, although it hardly tells you anything at all, just relatively useless guff like the box dimensions; there being nothing about shingled recording or the spin-speed, rendering it virtually useless. The FAQ is slightly more interesting.


Telecoms regulator Ofcom will not release details of its proposals for greater structural separation of Openreach and BT until the end of the year.In February the regulator stopped short of recommending a full separation of BT and Openreach in its Digital Communications Review.Ofcom will now draft its proposals for discussion between October and December, which will go before the European Commission to force the issue of greater independence.It said: We will develop detailed proposals to bring about greater independence and autonomy of Openreach for discussion with the European Commission, according to its Annual Plan for 2016/17.Ofcom will also publish plans to open access to BT's telegraph poles and ducts by competitors as part of its Wholesale Local Access market review, also due in the third quarter of the financial year.It said enhanced structural separation was needed as it had found evidence that Openreach still has an incentive to make decisions in the interests of BT, rather than BT’s competitors, which can lead to competition problems.


In a briefing following the publication of its once-in-a-decade review, Ofcom's group director Steve Unger said that in an ideal world the regulator would have recommended a formal separation of the businesses, due to the significant failings of the current model. However, the property and pension costs associated with that option led the regulator to reccomend a “formal separation in everything but name” approach.Ofcom chief Sharon White insisted that formal separation would remain an option for the regulator.When we describe this as an option over which we reserve the right, that is genuinely the case. It is not there in the background because we forgot to take it off the table.Jonathan Oxley, group director for competition at Ofcom, said BT had submitted voluntary proposals for reform but they didn't cut the mustard.Also speaking after the publication of the review, Mark Shurmer, BT's group director of regulatory affairs, said BT hoped it could still reach a voluntary agreement with Ofcom.He said: The alternative to a voluntary separation is that we would have to go to Brussels. That will be a long process, so it would be in everyone’s interest [to avoid that route].



The US Consumer Product Safety Commission (CPSC) says that the recalled battery packs - built by Panasonic - were shipped in 91,000 notebooks in the US and 10,000 in Canada between June 2011 and January 2016.The recalled batteries power Toshiba Satellite, Portégé and Tecra models and were sold through Staples, Office Depot and the toshibadirect.com website.The CPSC notes that some of the now-recalled packs were also sold individually or as repair kit by Toshiba.While Toshiba's website calls the recall voluntary, the CPSC is advising that consumers immediately check their notebooks and, if using a recalled battery, remove the unit and use AC power until a replacement is delivered.The CPSC said that it has received four reports of the batteries overheating and melting, though no injuries were reported.This is far from the first time notebook batteries have been recalled. The lithium-ion power packs are notoriously prone to overheating and catching fire when damaged, or due to manufacturing defects.Such recalls have in the past forced PC sellers to call back millions of notebooks from their owners and added up to cost component vendors hundreds of millions of dollars.


Some 1.5 million Verizon Enterprise customer records have been stolen and are being sold on a criminal hacking forum, according to reports.A trusted seller on a popular but shadowy unnamed criminal forum asked for US$100,000 for the database or US$10,000 for batches of 100,000 records, investigative blogger Brian Krebs reports.Verizon Enterprise counts 99 percent of the Fortune 500 among its customer base.Verizon told Krebs it had found and fixed a vulnerability in its enterprise client portal and is contacting customers.“Our investigation to date found an attacker obtained basic contact information on a number of our enterprise customers. No customer proprietary network information or other data was accessed or accessible,” the company says.The unnamed seller is also reportedly selling vulnerabilities in the Verizon website. Buyers will receive the stolen databases in MongoDB format.The information will be useful in crafting personalised, and therefore more enticing, phishing messages, which is a crucial first step in many attacks against enterprises. The idea is to simplify what Docker's developer relations director Mano Marks says (video below) is a “dependency hell” created by the multi-layer installation currently required – installing Docker Toolbox, then installing Docker Machine, and then configuring a suitable VM (like VirtualBox on OS X).Announced just before Easter, the Windows and Mac OS beta offerings are designed to let devs get a taste for Docker on the desktop or laptop, without having to run up a server implementation.For OS X users, the Docker engine runs in an Alpine Linux disto, using the xhyve Virtual Machine. Windows users can run it up on Hyper-V and use Docker to manage the virtual machine.



“All you need is Docker, git, and a text editor or whatever version control system and IDE you want to use,” Marks says in the video.The native applications have a native user interface, auto-update, and a bunch of bundled tools: Docker command line, Docker Compose, and Docker Notary command line.DNS servers and networking integration for OS X and Windows, to make it easier to access containers over the LAN;
In Mac environments, the native release is designed to work with the OS X sandbox security model: “we are working closely with Apple to achieve this”, the announcement notes.
Marks also notes that “you can develop apps on your machine without having the runtime or framework installed on your machine”.For Mac, the minimum requirement is OS X 10.10.3 (Yosemite) or above running on a 2010 or later machine with Intel support for memory management unit (MMU) like extended page tables. Windows users need a recent Windows 10 Pro and Hyper-V.Amazon Web Services (AWS) released WorkSpaces, Windows desktop-as-a-service, towards the end of March 2014.We took an early look, but encountered several niggling problems. Don't dive in: it will get better, was my conclusion.It is time for another hands-on, but first a quick recap. WorkSpaces provides a Windows desktop on Amazon's cloud. There are three specification levels:In addition, you can pay $15.00 extra per month for Microsoft Office Professional, or you can save $4.00 if you bring your own Windows 7 desktop license. There are clients for Mac, Windows, iOS, Android and Chromebook; other operating systems such as Windows Phone and Linux are not supported. Standard Windows RDP clients are not supported.

Batterie pour Acer AS07A51

Derrière cette nouvelle tendance, on retrouve bien entendu l’arrivée de Windows 8, qui préfigure le tout tactile sur ordinateurs portables. Il faut dire que l’interface a été pensée dans ce but. Ordinateurs portables en mains, on note immédiatement la différence. Le tactile est d’une efficacité redoutable pour ce qui est de la manipulation des menus, tandis que l’utilisation à la souris traditionnelle rend Windows 8 beaucoup moins agréable à manipuler et beaucoup plus lent à utiliser.Tous les exposants ou presque ont adopté des écrans tactiles, que ce soit pour les PC fixes, les ultrabooks ou les ordinateurs portables. Certains fabricants comme HP ou Samsung n’hésitent d’ailleurs pas à parler d’un futur standard. Dans le cas de Samsung par exemple, deux postes fixes Smart et un Ultrabook sous Windows 8 sont tactiles, alors que seulement deux Ultrabooks ne disposent pas de cette fonctionnalité. Interrogé par nos soins, le responsable produit de la marque nous a expliqué qu’avec Windows 8, c’était une tendance qui allait probablement se généraliser. Ainsi, si les Series 5 en bénéficieront dans un premier temps, les Series 7 et 9 devraient également y avoir droit avec les prochaines générations de hardwares. C’est en tout cas la suite logique de cette transition progressive…


La navigation étant nettement plus facile au tactile, il va de soi que le public devra changer ses habitudes, les ordinateurs portables et fixes se transformant en somme en “hybrides”, à mi-chemin entre les ordinateurs qu’on connaissait jusqu’à présent et les tablettes. Quant à ceux qui gardent de mauvais souvenirs avec les précédents modèles de terminaux, sachez que la nouvelle génération est d’une précision redoutable, même si le toucher n’est pas toujours aussi agréable que sur smartphone…Ceci étant dit, ce sera bien entendu au consommateur de valider cette tendance, les chiffres risquant d’influer beaucoup sur les décisions des constructeurs.Si on s’attendait à ce que Samsung dévoile l’un ou l’autre gadget sous Windows 8, il faut bien admettre qu’on n’imaginait pas voir débarquer tout un line-up de produits, rassemblés derrière une seule marque : ATIV. A l’IFA, Samsung a fait sensation en dévoilant pas moins de quatre nouveaux produits sous Windows 8.
ATIV, c’est le nom choisi pour cette nouvelle gamme de produits. Samsung laisse donc tomber “Focus”, un nom qu’il utilisait pourtant depuis les débuts de Windows Phone 7 pour ces quatre lettres pour le moins étranges qui sont un anagramme de VITA, la dernière console portable de Sony.



Au total, quatre produits de la gamme ATIV ont été dévoilés, mais ils risquent d’être plus nombreux à débarquer en octobre prochain, lors de la sortie de Windows 8. Premier appareil sous le feu des projecteurs : l’ATIV Tab. Cette petite tablette de 10,1″ équipée de Windows 8 RT s’adresse à tout un chacun. Comme l’a expliqué Samsung au cours de sa conférence, c’est l’outil rêvé pour les grands voyageurs, de par sa connectivité (ports USB 2.0 compris), sa légèreté (570 grammes) et sa batterie (8200mAh). C’est également l’une des tablettes les plus puissantes du moment, avec un processeur double-coeur d’1,5 Ghz, 2 Go de RAM, une résolution de 1366×768, la NFC, un port HDMI et deux appareils photos : un dorsal de 5 mégapixels et un frontal de 1,9 mégapixel. L’ATIV Tab sera disponible en deux modèles : de 32 ou 64 Go, selon vos désirs.


Seconde tablette présentée, l’ATIV Smart PC est ce qu’on pourrait appeler un hybride, mi-tablette mi-ordinateur portable. Ce modèle se base bien entendu sur l’excellent Transformer Prime, tant dans son design que sa conception. Il est composé d’un écran-tablette détachable, et d’un clavier qui permet de transformer à volonté la tablette en ultrabook. Equipé de Windows 8 Pro, cet appareil se destine davantage à la classe business. Il est équipé d’une puce Intel i5 et est disponible en deux versions : la version classique à 128 Go, et la version Pro à 256 Go de SSD. Ultra-rapide, il dispose également d’un look très classe et de fonctionnalités haut de gamme. On citera ainsi une connexion Wifi / 3G / 4G, des ports USB, micro HDMI, micro SD, un adaptateur Ethernet, et d’une batterie offrant jusqu’à 13,5 h d’autonomie pour la version classique. Pour les autres fonctionnalités, il faudra malheureusement attendre que Samsung se décide à en révéler davantage sur le sujet…


Sans grande surprise, Samsung a également dévoilé sa nouvelle gamme d’ultrabooks, sous Windows 8. Et ce sont les Series 5,7 et 9 qui passeront en premier sous Windows 8. Au programme : des terminaux entièrement tactiles, qui reprennent le look traditionnel des différentes séries, avec l’habituelle technologie SuperBright, qui permet de pouvoir lire sur l’écran même en plein soleil, des processeurs divers allant du i3 au i5, sans oublier une mémoire interne relativement importante avec pas moins de 500 Go pour le Series 5. Les prix, eux, devraient s’échelonner de 600 à 1300€ environ. Plus de détails sur les différents modèles au cours des prochains jours.
Enfin, et c’est sans doute la plus grosse surprise de cette conférence : Samsung a dévoilé son premier smartphone Windows Phone 8, l’ATIV S. Et selon les premières spécificités révélées, il s’agit d’un terminal haut de gamme, disposant d’un écran de 4,8″ HD Super Amoled, d’un processeur double-coeur d’1,5 Ghz, de la NFC de 16 ou 32 Go de mémoire selon le modèle (avec possibilité de rajouter de la mémoire), d’une batterie de 2300 mAh, et de deux appareils photos : un dorsal de 8 mégapixels et un frontal de 1,9 mégapixel. Bref, une bien belle machine, qui devrait débarquer le 29 octobre chez nous, à un prix encore inconnu.


Depuis plus de 10 ans, des systèmes de localisation permettent de retrouver sa voiture volée après quelques heures seulement. Coûteux (entre 1.000 et 2.000€), ces appareils étaient jusqu’alors réservés à une clientèle aisée. Aujourd’hui, il est possible de s’en procurer un pour la moitié du prix.
Les «systèmes électroniques et services de localisation pour la gestion des risques liés à l’utilisation des véhicules, comme par exemple le vol» sont un marché florissant. Une entreprise française, déclare même que «depuis 2002, elle récupère 93% des véhicules volés équipés de ses systèmes après-vol.» Un chiffre important, quand 50% seulement des véhicules volés (avec et sans systèmes de localisation) finissent par être retrouvés.Jusqu’à il y a peu, ce genre de système était plutôt coûteux. «Entre 1.000 et 2.000 € l’appareil», explique Anthony Tudal, directeur commercial de Cobra France, compagnie qui commercialise ce genre de traceurs, au quotidien économique «Les Echos». Conséquence: seuls les véhicules haut de gamme en étaient équipés. Cela ne valait pas la peine d’investir une telle somme pour protéger des véhicules peu chers.



Mais les choses sont en train de changer. Cobra vient de lancer le «CobraTrak 3.0», le premier système de protection «après-vol» utilisant la technologie GPS et qui permet aux propriétaires d’un véhicule de le suivre à distance grâce à un smartphone ou un ordinateur portable, connectés à Internet. Avantage notable de ce petit bijou technologique: il coûte deux fois moins cher.Cette avancée devrait donc permettre d’augmenter encore le nombre de véhicules retrouvés suite à un vol, puisque le marché s’ouvre désormais à une gamme de véhicules moins coûteux. Surtout si les propriétaires de Twingo 1 et de Smart Fortwo, les voitures les plus volées en France en 2011, commencent à équiper leurs quatre roues de ces traceurs.Point positif pour la Suisse, certaines compagnies d’assurances réduisent les primes de leurs clients s’ils acceptent de s’équiper de ce type d’appareils.Les propriétaires d’un véhicule équipé du nouveau traceur peuvent donc connaître sa position en toutes circonstances. Utile quand on peine à se souvenir de l’étage du parking auquel on s’est garé. Mais le système permet aussi de suivre à la trace les trajets de son conjoint ou d’une personne à qui on prêterait sa voiture. Ou d’être suivi à la trace, vu d’une autre perspective. Une mauvaise nouvelle pour la protection de la vie privée.

At least four suspected women were apprehended during a raid conducted in Khayaban-e-Muslim on Sunday. The accused women were identified as Sana, Khadija, Ariba and Zarmin.


The spokesperson said that the accused women were involved in drug peddling. The spokesperson also claimed to have recovered arms, ammunitions and narcotics. The suspects were handed over to police for further investigations.



Separately, half a dozen suspects including a political worker were arrested during ongoing targeted raids by paramilitary force in parts of metropolis.


A political worker was arrested during a raid conducted by Rangers troops in New Karachi Industrial Area while the raid was conducted on a tip-off. Rangers spokesperson said that the accused identified as Shoaib aka Kodo was affiliated with Muttahida Qaumi Movement-London and has been involved in various cases of crime including anti state speeches.


In another raid, Rangers also claimed to have arrested an accused, namely Hidayatullah alias Enayatullah during a raid conducted in Manghopir area. The spokesperson said that the accused was involved in various cases of robberies.


Social worker escapes another murder attack


A social worker escaped a second consecutive murder attack in less than four months in a city on Sunday. According to details, a 38-year-old Muhammad Ilyas, son of Muhammad Hussain, who is also associated with the computer hardware business and runs his own private company at New Karachi Industrial Area, came under attack near Saba Cinema in New Karachi Industrial Area police remits while he was on his way to his godown in the same area.


Police said that Ilyas, a residential of Block 17, Federal B Area was on his way to go-down in his car when at least four armed men riding on two motorcycles came close to him and opened indiscriminate fire at him. However, the victim remained unhurt in the incident as he sped up his car and reached the police station. The culprits, however, managed to escape.


Police said that this was the second such murderous attack on the victim in four months as earlier the unidentified persons attempted to kill him near Allah Wali Chowrangi in New Karachi area on April 2017.


They said that nothing could say exactly about the motive behind the incident as what the police investigators were investigating the case from different angles as he has been involved in social activities, property business, and computer related business as well as has a political background.


The police was looking for the culprits that would help the investigators in ascertaining the motive behind the incident. The case has been registered while further investigation was underway.


Zu meinen neuesten Erkenntnissen gehört: Wir sind nicht allein. Nein, nicht, was Sie denken, ich bin nicht übergelaufen zu Aluhutträgern und auch nicht auf der Suche nach übersinnlichen Phänomenen. Aber es ist eine Tatsache: Auch wenn bei uns niemand zuhause ist – es ist trotzdem jemand da.


Das weiß ich seit neulich Nacht. Ich lag im Tiefschlaf, als mich eine Stimme aus dem Traum riss. Irgendwo sagte eine Frau: Es ist Rauch im Raum. Äh, was?! Ich fuhr aus dem Bett auf und fragte mich zwei Dinge. Woher sollte der Rauch kommen? Und wer zum Teufel war diese Frau? Ich hörte ein Piepen, dann wieder: Es ist Rauch im Raum, eine sanfte Stimme, überbetont höflich und sachlich. Ungefähr wie die Ansagerinnenstimme bei diesen Filmen im Flugzeug, wenn sie sagen: Blasen Sie die Schwimmweste nicht im Flugzeug auf, und niemals erklären warum: Weil man sonst nicht mehr durch den Notausgang passt und mit dem Flugzeug untergeht.


Von irgendwo im Haus sah ich blaues Licht zucken, irgendwas stimmte da nicht. Während ich panisch durchs ganze Haus raste, Herd, Öfen, Kühlschrank und Katze kontrollierte und nirgendwo auch nur den geringsten Rauch vorfand, rief mir die Frau fast schon gut gelaunt hinterher: Das ist ein Test. Ah, Danke, dachte ich und überlegte, auf wen ich jetzt wütend sein sollte. Oder auf was.



Auf dem Rückweg ins Bett entdeckte ich die Täterin quasi nebenbei. Auf einem Regal lag ein blaues Ding, das rhythmisch blau aufleuchtete. Ein Rauchmelder.


Am nächsten Morgen lernte ich, das es zu einem System aus Kameras, Rauch- und Bewegungsmeldern gehörte, mit denen sich Häuser und Wohnungen per Smartphone überwachen lassen. Das las ich Internet. Angeblich wusste das System auch, was eine Person ist und was nicht, stand da. Hm. Dann war der nächtliche Test also pure, personenbezogene Bosheit?


Das blaue Dings liegt inzwischen in einer Schublade, ohne Batterie, darauf habe ich bestanden. Zusammen mit weiteren Rauchmeldern und anderen Warnsystemen, die sich irgendwie als nicht praktikabel erwiesen haben.

Batterie pour HP ProBook 4710s/CT

Comme son nom l’indique, Animate It est une application qui permet de créer des séances animées grâce à la technologie du stop-motion. Créée par les créateurs du film Wallace & Gromit, l’application facilite la création d’une séquence animée. L’application retouche en réalité les quelques photos que vous avez prises au préalable pour créer une suite fluide et animée. Très simple à utiliser, Animate It permet de créer de petits montages sympas en deux temps trois mouvements. Son seul défaut n’est au final de ne pouvoir ajouter du son après enregistrement de la vidéo…Annoncée lors de l’E3 dernier, la plate-forme PlayStation Mobile est finalement disponible. Elle met à disposition des utilisateurs de certains smartphones et tablettes Android plusieurs dizaines de titres PlayStation.PlayStation Mobile, c’est la nouvelle plate-forme “jeux” de Sony sur supports mobiles. Elle donne accès à un vaste catalogue de jeux téléchargeables exclusivement sur les terminaux compatibles – comprenez par là les smartphones et tablettes Xperia du constructeur ainsi que la gamme One de HTC. Pour l’heure, le catalogue n’est pas encore très large, mais de nombreuses nouveautés devraient être proposées à intervalles réguliers.En plus de tourner sur smartphones et tablettes, PlayStation Mobile est également compatible avec la console portable Vita, ce qui permet au fabricant nippon de booster son catalogue de jeux. Sur Vita, la section apparait automatiquement. Sur smartphones et tablettes en revanche, il faut télécharger l’application “PlayStation Mobile for Android”, disponible gratuitement sur le Google Play.


Pour l’heure, pas vraiment de titre révolutionnaire à noter. Les jeux proposés sont pour la plupart de mini-jeux qui coûtent entre 50 cents et 12,99 euros.Tout comme les autres fabricants, Dell ne se passera pas de Windows 8 pour la fin d’année. Le fabricant mettra en avant une gamme de trois produits, destinés à trois marchés totalement différents…Objet de convoitise pour les amateurs de tablettes, le Latitude 10 est une tablette de 10″ tournant sous Windows 8 “Pro”, plutôt que RT. Un argument de choix pour le fabricant, qui a souhaité offrir un produit compatible avec une large gamme de softwares et ce même si le prix de ce Latitude 10 sera forcément plus élevé que la moyenne. En pratique, il s’agira donc d’un PC portable sous forme de tablette. Il pourra être rattaché à un dock et divers accessoires pourront y être branchés, d’une manette à une souris en passant par un clavier. Pour le reste, le Latitude 10 sera doté d’un processeur Intel dual-core de 2Ghz, de 128 Go de mémoire (+SD), d’un appareil photo de 8 mégapixels, d’une sortie miniHDMI et même d’un lecteur d’empreinte.



Le grand frère du Latitude 10, le Latitude 6430u, s’apparente pour sa part à un ultrabook pur et dur, disposant d’un écran de 14″, et avec une résolution de 1366×768. Il tourne sur base d’un processeur Ivy Bridge (au choix i3, i5 ou i7), dispose de jusqu’à 8 Go de RAM et 256 Go de stockage SSD.Enfin, l’OptiPlex 9010 est un PC tout-en-un de 23″, avec écran tactile et écran rotatif, dont nous vous avions déjà parlé il y a quelques semaines.Si les prix de ces appareils ne sont pas encore connus, on sait déjà qu’ils devraient arriver le 25 octobre en magasin et visent principalement les professionnels. Un parti pris logique de la part de Dell, vu le nombre de fabricants à s’intéresser au consommateur lambda.Pocket Photo, c’est le nom d’une petite imprimante portable de 212 grammes seulement, équipée des technologies NFC et Bluetooth et capable d’imprimer en moins de temps qu’il n’en faut pour le dire une photo prise avec son smartphone ou sa tablette.


A l’heure où les jeunes asiatiques, friandes d’impressions et de mobilité, sont en quête d’accessoires toujours plus “tendance”, cette petite imprimante portable pourrait bien faire fureur en Corée. Certes, le format des photos en 2″x3″ rappelle à plus d’un titre les Polaroid, et ne donne pas une grande liberté aux utilisateurs. Néanmoins, la qualité d’impression montrée dans la vidéo de démonstration démontre à quel point cette technologie continue d’évoluer rapidement et pourrait rapidement remplacer d’autres formats d’impression…Disponible pour environ 130€, l’accessoire est fourni avec une application de retouche photo, téléchargeable gratuitement sur le Google Play.Nous connaissions déjà l’USB, l’USB 2.0 (devenu la norme), l’USB 3.0, censé devenir la nouvelle norme avec ses 4,5 watts. Désormais, il faudra également compter sur l’USB Power Delivery, une technologie révolutionnaire qui devrait permettre de recharger son ordinateur avec un simple câble USB…


Présenté en fin de semaine dernière à l’IDF, l’USB Power Delivery est la nouvelle norme USB, qui devrait devenir une réalité dès la fin de cette année. Soutenu par HP, Intel, Microsoft, Texas Instruments, Dell, Qualcomm et ST-Ericsson, l’USB Power Delivery est une technologie révolutionnaire qui permettra d’utiliser l’USB comme moyen de rechargement d’une batterie d’ordinateur portable et de tablette. En d’autres termes, l’USB Power Delivery sera tellement puissant qu’il sera capable de remplacer le câble d’alimentation.Supportant jusqu’à 100 watts, soit 20 fois davantage que l’USB 3.0, il devrait devenir la nouvelle norme dès 2014. Cette année, plusieurs terminaux devraient déjà être équipés de ce nouveau port, qui permettra de recharger des appareils nettement plus volumineux mais également de transférer de plus gros volumes en moins de temps.



Rétrocompatible, l’USB Power Delivery pourrait rapidement devenir un argument de vente pour les prochains modèles d’ordinateurs portables. Les fabricants semblent en tout cas bien décidés à exploiter cette technologie le plus rapidement possible et proposer une vaste gamme de terminaux compatibles aux horizons 2013.Parmi les autres atouts de l’USB Power Delivery, on note la bidirectionnalité de l’alimentation électrique, qui permettra d’interchanger la source de l’énergie et le destinataire. Ainsi, il sera possible de charger un périphérique USB à l’aide d’un ordinateur mais également d’utiliser ce périphérique pour recharger son ordinateur si jamais on tombe par exemple à court de batterie dans un moment critique. Une fonctionnalité qui changera définitivement nos habitudes…Véritable jackpot pour l’industrie des technologies, l’USB Power Delivery pourrait donner un coup de pouce à plusieurs secteurs, dont celui des ordinateurs, qui souffre de fortes carences depuis plusieurs trimestres…

Akku für Dell Latitude E5420 ATG

Das auf Computerhardware spezialisierte Unternehmen HP kann mit Blick auf die Umsatz- und Gewinnentwicklung derzeit keine sonderlich üppigen Wachstumsraten aufweisen. Die seit dem Jahreswechsel zu beobachtende Performance kann sich mit über elf Prozent aber durchaus sehen lassen. Obwohl die Gewinnmargen etwas niedriger als bei der Konkurrenz ausfallen, scheint die Firma die Probleme vergangener Jahre bewältigt und die damalige Existenzkrise überstanden zu haben. Gemäß den von FactSet Research Systems erfassten Prognosen wird beim Gewinn pro Aktie für das abgelaufene dritte Quartal ein Wert von 0,42 Dollar pro Aktie prognostiziert. Für das mittlerweile laufende vierte Quartal wird ein leichter Zuwachs auf 0,44 Dollar erwartet.


Bei den ausgesprochenen Analystenurteilen dominiert derzeit der Optimismus. Von den insgesamt 23 von FactSet Research Systems empfiehlt eine Mehrheit von 12 Analysten die HP-Aktie zum Kauf ("Buy"), während zwei Aktienexperten zum Übergewichten ("Overweight") raten. Neun Analysten stufen den Titel als Halteposition ("Hold") ein, negative Analystenbewertungen gibt es derzeit hingegen keine. Die ausgesprochenen Kursziele reichen von 18,75 bis 23,00 Dollar und ergeben einen Mittelwert von 21,06 Dollar (aktuell: 18,51 Dollar).


In den vergangenen fünf Jahren verzeichnete die Aktie von HP eine heftige Berg- und Talfahrt in einer Range von 5,30 bis 19,50 Dollar. Seit Anfang 2016 bewegt sich der Technologiewert in einem intakten Aufwärtstrendkanal, dessen untere Begrenzung bei 17,50 Dollar angesiedelt ist. Ein Verletzen dieser Marke könnte chartinduzierten Verkaufsdruck aufkommen lassen und zu einem Unterschreiten der im Bereich von 17 Dollar angesiedelten Unterstützungszone führen. Aktuell befindet sich der Wert aber eher auf Tuchfühlung mit einer markanten charttechnischen Widerstandszone. Um sie nachhaltig zu überwinden, wäre vor allem eines hilfreich: eine positive Überraschung beim Update am Mittwoch.


Popular virtual reality headsets such as the Oculus Rift are tethered to a PC, significantly limiting freedom of movement. So HP has put a VR-capable computer into a backpack – but it's very much for business, not entertainment.



HP describes its new Z VR Backpack as “the world's first professional wearable VR PC”.


Features include a 16GB Nvidia Quadro P5200 graphics processing unit and an Intel Core i7 vPro processor to minimise disconcerting dropped frames, and hot-swappable batteries to extend session lengths.


Potential applications can be found in a wide variety of fields – HP has mentioned product design, architecture, healthcare, first responder training, automotive, retail and entertainment.


For content creators, a docking station will speed the transfer of VR models from development PCs to the Backpack.


The Z VR Backpack is scheduled to go on sale in September – prices have yet to be announced, but don't expect it to be cheap. A VR “immersion centre” will open in Sydney before the end of the year so that customers can experience VR technology and consult HP’s experts.


Researchers at New York University Abu Dhabi said they have created an 'unhackable' chip to shore up the defences of computer hardware, in an age of increasing threats to individuals and companies across the globe.


This is the first working prototype of a chip that has security features or locks implemented as part of its hardware design, protecting it from hardware-level - rather than software - threats.


Ozgur Sinanoglu, NYUAD’s associate dean of engineering for academic affairs and head of the university’s Design for Excellence lab, has previously said malicious computer components - so-called Trojans - could be physically installed in factories or manufacturing labs. This would allow those behind the plan unfettered access to devices.


The chip has a secret key that makes it virtually impossible to access and would only function for authorised users.


“Without the secret key, the chips cannot be made functional,” he said.


“The functionality of chip - what it does, how it does it - can only be known if the secret key is known.”


A patent application has been filed at the US Patent Office. The researchers are creating a web-based platform to make information about the chip available to the public.


An extensive research paper by NYUAD’s Design for Excellence team will be presented in November at the ACM Conference on Computer and Communications Security in the US.


“These are all theoretically proven points and we will present this at a top cyber security conference, but we need to test our claims practically as well," said Mr Sinanoglu.


"We will create a web-based platform to make all information about this chip available to public. We will ask researchers to act as hackers and retrieve the secret key of our chip or reveal the exact functionality of our chip design based on this information."



There has been growing concern about cyber security and calls for solutions to secure systems from hackers following the WannaCry ransomware attack.


WannaCry infected files, shut down hospitals, banks, transport systems and industry and affected more than 150 countries in May.


On Saturday afternoon, people noticed a man running suspiciously and given many such incidents in the neighbourhood in the recent past, thought he was a chain-snatcher. The residents caught him and though he denied having anything to do with chain-snatching, thrashed him before calling police.

Subramanyanagar cops rushed to the spot and took him to the station. The man was identified as Prabhakar, 40, a computer hardware engineer. A resident of Kammanahalli in east Bengaluru, Prabhakar said he was part of a gang led by Altaf from RT Nagar. "The accused was carrying Rs 1 crore in demonetized Rs 500 and Rs 1,000 notes. We seized the demonetized currency from him," an officer said.


"Five people, including Altaf, reached Gayathri Nagar on Saturday and a misunderstanding between the gang members resulted in a clash. Altaf asked Prabhakar to leave the area with the cash, but he was caught by residents instead outside Altaf's house," a police officer said. "We have registered a case against Prabhakar and the gang. The accused said he was not aware of the source of the money. We are hoping to catch Altaf and find more about the source," the officer added. Police said they were investigating Prabhakar's claims that he had no criminal antecedents.

Next, if you want to access this quantum processor, you have to sign up for an account. Which means you must reach this page...
...and fill out an invitation request. If you hear back from IBM, you're in, presumably.IBM doesn't get it. It's not 2007 any more. The cloud today is on-demand computing, delivered virtually instantly at scale. You pick a username, you enter a password, you hand over your credit card number, you get into the service immediately. You start using it.Since when has invitation-only limited access to scientific experiments been the cloud? How exactly do you share a five-qubit processor at scale? It's too bad Big Blue can't ask its cloud chief technology officer: he left recently, along with other top-brass and all the staffers axed in an ongoing restructuring.Don't ask Arvind Krishna, senior vice president and director of IBM Research, either. This moment represents the birth of quantum cloud computing, he said in a canned quote, again demonstrating that IBM Research has a totally different definition of the word cloud to Amazon, Google, and Microsoft.


It's IBM Watson-as-a-service all over again. Can't someone at SoftLayer or IBM Bluemix have a word?PR spin aside, you're not going to rewrite textbooks with five qubits. In 2001, IBM scientists factored 15 into three times five using a seven-qubit processor. In 2013, physicists in China factored 143 using four qubits. In 2014, researchers were able to factor 291,311 using only 6 qubits. Your humble hack's 2.2GHz Core i5 laptop was able to calculate it instantly: 523 times 557.

Classic computer bits are either one or zero; on or off; true or false. Quantum bits are either zero, one or a superposition of both. Quantum computers are expected to be able to process calculations far faster than classic binary bits by coupling this three-state capability with other quantum effects. It's something that's been promised for decades.Quantum computing has a long way to go. IBM reckons 50 qubits are needed to top the fastest known supercomputers of today, and 100 qubit CPUs should be possible in the next decade. IBM's five qubit system is a fairly big hulking thing; the brains of the processor must be kept in a cryogenic dilution refrigerator to minimize the effects of heat and electromagnetic radiation.

Providing this kind of facility remotely to scientists is a nice gesture by IBM Research. Maybe one day it can scale. But dressing up this experimental technology right now as a quantum-computing-as-a-service free-for-all is absurd.One tech news site declared this morning: IBM just beat Google to a brand new type of computing. Swap computing for marketing and you're on the right track. Brocade has reset Q2 revenue expectations lower, citing a weak SAN market and continued IP networking headwinds. Instead of revenues between $542m to $562m, it now expects them to be between $518m to $528m. This is $523m at the mid-point, 4.4 per cent down on a year ago. CEO Lloyd Carney talked of a general softness in IT spending. William Blair analyst Jason Ader said: We suspect that weak systems sales, as well as a general shift to IP connectivity in storage, may have finally caught up to Brocade's FC networking business. To a lesser extent, Brocade may also be suffering from customers waiting for the next product cycle (32 Gbit/s), which is expected to kick in toward the end of the calendar year. Full results are expected on 19 May. WAHckon University students in the Australian city of Perth have landed in hot water, with one charged by Police, after finding and exploiting severe holes to rewind travel charges incurred using the city's SmartRider public transport smart card.


The Murdoch University students reported the flaws to SmartRider operator TransPerth and inflicted what is estimated to be about $18 in losses which were covered in later balance recharges, however local authorities considered the university security research an act of fraud.One student is appealing a conviction while a second involved only in the earlier parts of the research effort was not charged.Murdoch University second year student Jack Carruthers pled guilty and was handed a spent conviction, a type of criminal conviction that does not result in a permanent record that will show up in background checks.Carruthers and his colleagues undertook the research as part of their university security club Hack The Planet. Carruthers is the club's president.Members exploited the identified flaws in an effort to demonstrate the vulnerabilities at Perth train stations, in the knowledge that the act could see them breach state laws.Carruthers and his fellow researchers found still-existing failings in the MIFARE Classic SmartRider system that allowed them to roll-back charges to cards enabling free travel.


It is possible to replay an autoload (direct debit recharge) and keep getting more credit, Carruthers told the WAHckon security conference in Perth, last Sunday.The costs came out to $18 and the smart riders had $20 worth of credit, so I thought we were in the clear but the judge was of the opinion that my damning confession was all that was needed.Officers showed up on Carruthers' door about two months later, taking his laptop and 'all of his clothes' to prove his was the individual captured in CCTV photos.The researchers say the project was documented as part of the hacking club in what could conceivably demonstrate the academic intention of the work.The conviction comes at a time when the Turnbull Government under its Cyber Security Strategy is spending big to in part help lure and train students to information security university courses.Carruthers says TransPerth is planning a fix but will likely must invest in an expensive upgrade of cards to systems including the more secure MiFare DESfire EV2.He says the agency says it will remain vigilant for possible reload attacks until the upgrade.MIFARE Classic is long known to be vulnerable to compromise. The Christchurch bus system which then operated the platform was popped in similar 2013 research by Melbourne security bod William Turner who found he could load cards with any amount of money.



It was told to implement training and guidance or face court action following a data breach that led to a child's medical reports being stolen.The council just west of Glasgow has been audited twice in 2013 and advised to improve its data-handling. It failed to do so, and in 2014 an employee left a laptop and paperwork on an adoption case in a car overnight, from which it was stolen.Ken Macdonald, assistant information commissioner for Scotland, said: “Let’s be clear, what we’re asking for here is a basic requirement for an organisation that is trusted with large amounts of local people’s personal data.” When is ad-blocking ethical? How about when the adtech industry is behaving so unethically it destroys people’s livelihoods?Musician and music rights campaigner David Lowery last year made the incendiary suggestion that musicians should encourage their fans to block the advertising running on music-streaming sites – even though in the short term, it’s the musicians themselves who’ll take a hit in income. With the rise in ad-blockers, his idea is topical again, so let’s have a look at the merits of the argument.

What does this mean? The NTIA isn't sure beyond the fact that something clearly needs to be done. It points out that its analysis has only scratched the surface but even that initial review has made it clear that policymakers need to develop a better understanding of mistrust in the privacy and security of the Internet and the resulting chilling effects.It warns, not without some justification, that unless something is done to increase trust it may reduce economic activity and hamper the free exchange of ideas online.There are some policy plans afoot: the Obama Administration has put out draft privacy legislation, and the NTIA is running a number of processes with a range of stakeholders on online privacy and cybersecurity, including its current one on the internet of things.The release of this data however demonstrates that there is a very real impact of security and privacy breaches. And it blows apart the idea that a move to online activities is somehow inevitable by showing that people do in fact scale back when impacted. That reality may serve as a catalyst for businesses to get serious about fixing problems and invest in make the online experience a safe, more secure one. Students who have access to computer devices in the classroom do significantly worse than colleagues without them, a study has found.


In a study by MIT's School Effectiveness & Inequality Initiative, titled The Impact of Computer Usage on Academic Performance: Evidence from a Randomized Trial at the United States Military Academy, students whose classroom access to computer devices was prohibited performed better in exams.726 undergraduates studying an introductory economics course at the United States Military Academy were randomly separated into three groups.A control group was prohibited from using any laptops or tablets, another had access to tablets which were required to be flat on the table at all times, while the third was free to use tablets and laptops.The researchers found that permitting computers or laptops in a classroom lowers overall exam grades by around one-fifth of a standard deviation.The reasons for this were unclear, however, as a number of factors could potentially contribute to the lower scores, including the ease at which students could be distracted by surfing the internet, lowered note-taking skills, and changes in the teacher's behaviour when interacting with students on a computer.We want to be clear that we cannot relate our results to a class where the laptop or tablet is used deliberately in classroom instruction, as these exercises may boost a student’s ability to retain the material . Rather, our results relate only to classes where students have the option to use computer devices to take notes.
We further cannot test whether the laptop or ta blet leads to worse note taking, whether the increased availability of distractions for computer users (email, facebook, twitter, news, other classes, etc.) leads to lower grades , or whether professors teach differently when students are on their computers.



They conclude: Given the magnitude of our results , and the increasing emphasis of using technology in the classroom, additional research aimed at distinguishing between these channels is clearly warranted. Fluent, founded in May 2015 and now with $2.5m to its name, will use the new cash injection to expand its engineering team and expand sales.

Google has decided that emoji need to offer better role models for women and has therefore proposed 13 new ones, all depicting women in the workplace.Google's proposal (PDF) says the company “wants to increase the representation of women in emoji” and therefore suggests “a new set of emoji that represents a wide range of professions for women and men with a goal of highlighting the diversity of women’s careers and empowering girls everywhere.”


Google's four submitters cite a New York Times op-ed by Amy Butcher in which she wrote “How was there space for both a bento box and a single fried coconut shrimp, and yet women were restricted to a smattering of tired, beauty-centric roles? This was not a problem for our male emoji brethren. Men were serving on the police force, working construction and being Santa. Meanwhile, on our phones, it was Saturday at the Mall of America — women shopping while men wrote the checks.”The four Googlers also point out various studies that show women are the main users of emoji, so surely deserve emoji that go beyond cliches.The thirteen chosen emoji are also based on research into the most common occupations and take into account recent campaigns encouraging women and girls into professions in which they are under-represented.Emoji usually have secondary representations, but Google argues its 13 proposed characters should be depicted as women only because that's the point of this whole idea.The proposal ends with a call for “other members of Unicode to join us in creating a system of emoji design that can accommodate a broader gender spectrum.” Under the deal it will provide communications in remote areas and additional network resilience. Mansoor Hanif, director of Radio Access Networks at EE, said the deal will enable the biz to deliver a truly nationwide 4G network to rural areas.



BlackHat Asia A world-first proof-of-concept worm - if unleashed - could spell disaster for the world’s critical infrastructure, including power utilities by making attacks exponentially more difficult to detect and stop.It is a stand-alone attack but The Register has confirmed a realistic stealthy end-to-end attack scenario can be produced by combining two independent research efforts.The programmable logic controller (PLC) worm is the brain child of German hackers Ralf Spenneberg and Maik Brüggeman of Steinfurt-based consultancy OpenSource Security Ralf Spenneberg, and, unlike any past attacks, is able to spread from devices without the need of an infected laptop or desktop.All other PLC malware such as Stuxnet relied on having an infected computer to spread to other controllers, meaning an infection could be stopped from proliferating by removing those machines.Spenneberg and Brüggeman claim the attack spreads like cancer between default Siemens S7 1200 PLCs, and could be reworked to target other systems.They say it can also be used in proxy-chains to gain a foothold into utility networks, depending on the PLC used.

Batterie pour ASUS A42-G53

Vous pourrez acheter l’iPhone 7 si vous pouvez tolérer la problématique des écouteurs, surtout si vous êtes du genre à changer d’iPhone chaque année, dès lors que vous en avez les moyens.Mais, en dépit des améliorations incontestables, ce nouvel iPhone n’est tout simplement pas aussi convaincant que beaucoup de ses prédécesseurs. Certains pourraient vouloir attendre un an pour le prochain opus — et peut-être une meilleure solution audio pour démarrer.
The Verge : "Attendez l'iPhone de l'année prochaine"The Verge : « Attendez l’iPhone de l’année prochaine »
Vous l’aurez compris, si certains pensent que passer à l’iPhone 7 est une excellente chose, d’autres suggèrent d’attendre l’année prochaine, pour un iPhone qui fêtera son 10e anniversaire. On s’attend à de belles choses. On se retrouve donc l’année prochaine à la même date ?En juillet dernier, nous avons entendu dire que la mise à jour d’anniversaire pour Windows 10, « Anniversary Update », serait déployée progressivement, étape par étape, et arriverait par vagues. La firme de Redmond avait alors mentionné que cela « prendrait un certain temps ». Mais, nous n’avions pas anticipé sur la notion « d’un certain temps ».


La déclaration de Dona Sarkar à l’époque ne voulait pas dire que tout le monde n’aura pas la mise à jour durant la première ou la deuxième semaine, mais en fait, que chaque PC recevrait celle-ci en août, voir en septembre pour les plus malchanceux. Mais, certaines personnes ne l’ont pas encore, elles ne l’auront peut-être pas avant fin septembre, voir octobre.Selon de nouveaux détails découverts par ZDNet, Windows 10 Anniversary Update pourrait arriver que début novembre pour ceux qui ne l’ont toujours pas.Dans un e-mail, Microsoft a déclaré : « la mise à jour anniversaire va se télécharger et s’installer par Windows Update. Le téléchargement se fera automatiquement, dès le début du déploiement le 2 août 2016. Ce processus pourra prendre jusqu’à 3 mois pour atteindre tous les utilisateurs… »Windows 10 Anniversary Update est déployée très très lentementWindows 10 Anniversary Update est déployée très très lentement
Bien sûr, il y a un côté positif à avoir à attendre si longtemps. En effet, les adopteurs précoces, ceux ayant déjà la mise à jour, ont trouvé quelques défauts assez désagréables, et ceux-ci ont été rafistolés petit à petit. Un bon exemple est le bug qui entraînait divers freezes du PC. De plus, les problèmes de webcam devraient également être résolus avec un patch ce mois-ci.



En effet, comme le note ZDNet, une partie de la raison de la lenteur du déploiement est que Microsoft peut suivre les progrès et les bugs, et ainsi prendre des mesures appropriées avec les différents retours. Cependant, espérons que la longue attente soit vécue par une très petite minorité d’utilisateurs, peut-être ceux fonctionnant sous Windows 10 sur des appareils moins courants.Pour ceux qui restent impatients, les clients de Windows 10 peuvent manuellement lancer la mise à jour en allant sur la page de téléchargement de Windows 10 et en cliquant sur le grand bouton bleu « Mettre à jour maintenant ». Cela permet de lancer l’assistant de mise à niveau de Windows 10 qui va télécharger les fichiers en arrière-plan, et permettre à l’utilisateur de choisir quand mettre à niveau le périphérique.L’un des éléments clés et peut-être le plus discuté sur l’iPhone 7 est le retrait de la prise casque de 3,5 mm, comptant plutôt sur le port Lightning ou des casques sans fil. Et, il semble que Samsung pourrait projeter quelque chose de similaire dans un proche avenir.


Deux sources « impliquées dans la chaîne d’approvisionnement des smartphones de Samsung » ont évoqué le sujet à Digital Music News, rapportant que Samsung, aux côtés d’autres fabricants Android, pourrait non seulement opter pour une prise casque propriétaire, mais également bloquer l’octroi de licences à Apple.Si cela est vrai, cela pourrait être considéré comme un geste de vengeance par la communauté Android, et pourrait forcer les fabricants de casques à choisir leur camp. Et avec plus de dispositifs Android que de iDevices, Samsung pourrait bien avoir la priorité.Ce serait de mauvaises nouvelles pour Apple et de mauvaises nouvelles pour tous ceux qui utilisent les deux mondes, à savoir iOS et Android, car cela pourrait forcer l’utilisation d’adaptateurs.When you’re trying super hard to make the relationship work pic.twitter.com/Ro3H1DgOC9Mais le choix ne serait pas une mauvaise chose. Alors que le choix d’Apple pour un port propriétaire peut provoquer la colère des fabricants Android, on peut légitimement penser que le retrait du port de 3,5 mm est une bonne chose. Celui-ci permet d’économiser un précieux espace, et les nouvelles technologies peuvent potentiellement offrir une plus grande qualité sonore.



En fait, l’une des sources affirme que Samsung vise à améliorer la qualité du son avec un nouveau port casque. Quoi qu’il en soit, la solution envisagée par Samsung ne devrait pas poser trop de problèmes pour tous ceux qui sont habitués aux dispositifs Android, puisque la prise exclusive de Samsung sera apparemment conçue avec tous les fabricants Android autour de la table, en leur offrant des licences peu chères ou gratuites.DonglesSoit un adaptateur, soit du Bluetooth ! Faites votre choix…
Mais, cela pourrait fragmenter davantage l’industrie du casque, et faire de l’audio sans-fil une option beaucoup plus attrayante – libérant les utilisateurs de, non seulement fils, mais également des ports propriétaires.Pour l’instant, bien que ce soit tout juste une rumeur, et alors que les jours du port jack 3,5 mm sont probablement comptés, il est trop tôt pour dire exactement quand ou comment il sera abandonné. Étant donné tous les tracas impliquant le remplacement de la prise casque, il semble très peu probable que le changement arrivera bientôt.

About Asus

ASUSTeK Computer Inc., known as ASUS, is a Taiwanese multinational computer hardware and electronics company was founded in 1989 in Taiwan. ASUS is one of the world's largest computer hardware companies. Its products include desktops, PC peripherals, laptops, smartphones, tablets and hybrid devices. The company has made Android phones powered by Intel and Qualcomm SoCs.


Following the modest strength seen in the previous session, stocks moved sharply lower over the course of the trading day on Thursday. With the sell-off on the day, the S&P 500 dropped to its lowest closing level in over a month.


The major averages ended the session at their worst levels of the day. The Dow tumbled 274.14 points or 1.2 percent to 21,750.73, the Nasdaq plummeted 123.19 points or 1.9 percent to 6,211.91 and the S&P 500 slumped 38.10 points 1.5 percent to 2,430.01.


The broad based weakness on Wall Street reflected concerns about ongoing political turmoil in Washington, D.C.


The backlash to President Donald Trump's response to last weekend's violent events in Charlottesville, Virginia, has led to worries about the president's pro-business agenda.


Reports that Gary Cohn is considering resigning as Trump's top economic advisor weighed on Wall Street, although the White House has denied the claims.


Cohn, former president and chief operating officer of Goldman Sachs (GS), currently serves as the Director of the National Economic Council.


"Nothing has changed," a White House official said. "Gary is focused on his responsibilities as NEC Director and any reports to the contrary are 100% false."


Cohn was reportedly "upset" and "disgusted" with Trump's remarks indicating blame for the clashes between white supremacists and counter-protesters should be shared by both sides.



Traders also reacted negatively to the latest batch of earnings news, with Wal-Mart (WMT) and Cisco Systems (CSCO) moving lower after reporting their quarterly results.


Like every year since its inception, the E-Sports and Gaming Summit (ESGS) will serve as one of the Philippines and Southeast Asia’s largest eSports and gaming conventions this 2017. To whet our appetites for what’s heading our way, organizer Gariath Concepts has been doling out information about the international companies that will be present at the event.


So let’s cut to the chase: this October 27 to 29 at the SMX Convention Center, Mall of Asia Complex, ESGS 2017 will play host to gaming industry giants Sony Interactive Entertainment and Ubisoft, who will be at the event as official major exhibitors. Capcom will also be present as an official exhibitor.

Battery for Samsung RF511

There is a little bit of processor and memory load to pull this off, but it's well within the scope of Chromebooks that use either Intel or ARM processors, he explained. Chromebooks are more powerful than the smartphones that Android apps are designed for, so processors will have little problem running the mobile code.The system does have its limits, however. Android apps that require specific hardware, like an always-on cellular link, won't run on a laptop that doesn't have the necessary kit. But that's not as big an issue as you might think, Liu opined.For example, while some apps require GPS (something very few laptops bother to install), what they are actually after is location information, and that can usually be provided by WiFi systems.That said, according to Liu, the addition would give a spur for manufacturers to build more hardware into premium models. It's possible – cellular-connected Chromebooks have traditionally been the red-headed stepchild of the platform and supporting the connections for Android users could prove popular.Google didn't announce any new Chromebooks in its Pixel line, but said new hardware would be coming out from other manufacturers when Android is fully integrated later this year.


Overall, Google was very pleased with the Chrome OS model, Liu said, citing figures from IDC saying that the platform is now outselling Macs in the US. Fifty million schoolchildren are now using Chromebooks, he said, and there was potential for great growth in the enterprise market.Liu said that the Android addition would be included in the next developer release of Chrome OS, M53, in the next few weeks, and then on to consumers later in the year when the bugs have been sorted out. Desktop-as-a-service in 2016 is about as mature as infrastructure-as-a-service was in 2008, so waiting until it matures is more sensible than diving in now.So says Garter for Technical Professionals' analyst Mark Lockwood, who The Register's virtualisation desk beheld yesterday at the firm's Infrastructure Operations & Data Centre Summit in Sydney.Lockwood said DaaS currently lags desktop virtualisation (VDI) in many ways, especially on cost. Best-practice VDI costs about US$300/seat/year. DaaS costs more. VDI doesn't have latency problems. DaaS does and those problems only get worse if your desktops have to come in over the WAN to reach data inside the firewall, pipe that data into the cloudy desktop and then send it to users over the WAN again.Current DaaS offerings are also a little unrealistic – the base configuration of a single CPU with 2GB of RAM is not useful for most applications. More realistically-specced machines cost about US$50/month. Suppliers are also thin on the ground. Today only Amazon Web Services and VMware provide a single-throat-to-choke experience. Other providers can split bills so you pay for VDI licences and for the cloudy desktops.



On the upside, Lockwood said VDI is a notoriously finicky application that requires a big up-front investment and even then often needs tweaks. In typical cloudy style, DaaS requires no up-front spend. DaaS' elasticity is also helpful for businesses that employ seasonal workers. With on-premises VDI you need to buy for peak user numbers and then wear the cost of idle infrastructure. DaaS is also nicely secure: if a mobile worker uses a cloudy desktop on a properly-secured device, sensitive data should be out of reach to whoever it is finds a laptop or iPad in an airline seat..Like all cloud services, DaaS will of course get better and cheaper. But Lockwood said there's no point in waiting for DaaS to improve if VDI is something you need now. That's because DaaS is still rather immature, but just as IaaS has come a long way in a short time Lockwood expects it won't be long before the list of reasons not to consider DaaS becomes rather shorter. Nearly half of all Americans have not carried out a normal online task because of security and privacy fears, according to a new survey by the US government.Forty-five per cent of the 41,000 households contacted said they had decided not to do online banking, or buy goods online, or post on social networks because they were worried about what might happen. Just under a third of them said they had stop several of those activities over the same fears.


The survey by the Department of Commerce's National Telecommunications and Information Administration (NTIA) makes for sober reading. It also makes a direct connection between people scaling back their online activities and the impact of a wave of recent security breaches of personal data.An extraordinary 19 per cent of households - which extrapolates to nearly 24 million households across the US - have been personally affected by an online security breach in the past year.That's perhaps not surprising given the big-name consumer companies impacted, including, to name just a few: Target, Home Depot, Verizon, Wendy's and Kiddicare - the last two reported just this week.Those that have been the victim of a data breach are significantly more likely to scale back their online activities, the survey found: on average nine per cent.The data also reveals a sad truth: the more you do online, the more likely you are to have your information compromised.Of households that reported only having one online device like a computer or laptop, just six per cent of them said they had been victim of a data breach. That percentage goes up almost linearly to an appalling 31 per cent of households with five or more online devices.



Households Reporting Online Security Breaches by Number of Different Types of Devices Used, Percent of Households with Internet Users, 2015
In that respect, the decision by more and more American to opt out of online tasks is a logical one. But it is also one that has significant economic impact given the extent to which companies are moving their goods and services online.Every day, billions of people around the world use the Internet to share ideas, conduct financial transactions, and keep in touch with family, friends, and colleagues, an NTIA policy analyst Rafi Goldberg wrote in a related blog post.Users send and store personal medical data, business communications, and even intimate conversations over this global network. But for the Internet to grow and thrive, users must continue to trust that their personal information will be secure and their privacy protected.Of people's fears, identity theft sits at the top with 63 per cent of people citing it as a real concern. Second comes credit card and banking fraud with 45 per cent. Then data collection by online services, loss of control over personal data, data collection by the government, and threats to personal safety with 23, 22, 18 and 13 per cent respectively.

Even if you do trust whoever issued the certificate it doesn't mean much if the network cannot be trusted. A lot of experts claim “HTTPS is broken” and here is one small example of why. If you sit in a coffee shop and go surfing you can quite easily end up being the victim of a man-in-the-middle (MitM) attack. All a potential attacker needs is a copy of Kali Linux, a reasonably powerful laptop and coffee!But wait, you cry, aren't certificates supposed to protect us from exactly this type of thing? Yes but... essentially in our coffee-shop scenario the connection can be forced to run via the MitM laptop using a program called SSLstrip to copy the data as it is passed back and forth to Gmail. We get the traffic from the victim by poisoning the ARP cache and pretending to be the router. SSLStrip forces a victim's browser into communicating via an attacker’s laptop in plain-text over HTTP, with the adversary proxies the modified content from an HTTPS server.The HTTPS between Gmail and you is now readable because you get the decrypted plain text data before it is encrypted and sent to Gmail.


It isn't just coffee shops that present this risk. Frequently, SSL inspection is used in offices of larger companies to monitor staff web activity. Several companies such as FireEye and Bluecoat provide specialised appliances to do this at wirespeed, essentially rendering them unnoticeable. Governments can also do the same using FinFisher or other tools running on ISP networks.This is one of the main reasons I tell people not to check their web mail on their work computer. Employers probably have the right do that written into their employment terms and conditions. Companies do, however, have other more legitimate reasons for breaking SSL scanning for malware-related traffic and data loss prevention (DLP being the new hot ticket item). If you couldn't look inside an encrypted packet you would have no idea what's flowing across the network most of the time other than source and destination.What are the mitigations against all these for the average Joe user? In reality not a lot. Use your common sense when connecting to a Wi-Fi hotspot. Ask yourself:On a larger scale there are a few things that can be done but require effort. If a site provides only HTTPS then sslstrip would fail as it can't fall back to HTTP. Also browsers are becoming better at dealing with these types of issues.



Some browsers such as Chrome use a new technique called certificate pinning. This technique creates a digital fingerprint for each HTTPS site visited and afterwards compares it to the certificate being presented. It will warn the user if things don’t look as they should. Another method that site owners can use to protect their clients is HSTS. This tells the browser on first visit that the site is HTTPS only and therefore the browser should only ever connect to via HTTPS for a determined length of time.Any attempt to redirect the browser to an HTTP version of the site will be stopped by the browser. The one weakness with this technology is that the browser has to have first visited the genuine site to receive the HSTS response. But if you make sure you've visited a site that supports HSTS on a trusted network, your browser will then ensure it is never redirected to HTTP.A site owner who knows they will only ever use HTTPS and uses HSTS (HTTP Strict Transport Security) can have their website added to a HSTS preloaded list in the Chromium project. Getting your site added to that list means that Chromium will never allow an unencrypted connection to your site.


A lot of companies who deploy monitoring will often install their own root certificates on company computers. This lets the proxy devices to self-sign certificates for any domain and be trusted by the computers.HTTPS is not the silver-bullet online defence shield a lot of users believe it to be on public networks, meaning activities such as online banking and shopping are done at their own risk.While there are some additional steps you can take, you should - therefore - continue to exercise caution when using a network you don’t control and think about the type of information that you may be sharing with people you may not want to. Something for the Weekend, Sir? I’m on stage with a gun pointing at my heart. There is the sound of nervous shuffling as those sitting in the stalls squirm in their seats. Then silence: the audience quickly falls still and holds it breath. The man armed with the musket is raising the muzzle to take better aim before slowly squeezing the trigger…What? He’s ruining my bullet-catching act. It’s supposed to be the climax of an thrilling evening of astounding feats of prestidigitation, not a light-hearted moment of improv.What’s so frustrating is that I took considerable pains to set all this up, what with the years of rehearsal, hiring all the Chinese acrobats and building a time machine so that I could travel back to 1918 just for this one-off performance. And now my invited member of the audience is cocking it up.



All he had to do was inspect the gun, a fake antique (with the emphasis on “fake”), help load it and fire one shot in front of a full house of paying spectators. All I have to do is stand dramatically at the other side of the stage and pretend to catch the bullet on a china plate. Simples.Except the fellow coolly hands the old wooden-stocked gun back to one of my assistants, reaches into his coat and pulls out an Uzi sub-machine gun.Before I can point out to him that the Uzi won’t be invented for another 30 years, he has emptied the magazine in less than three seconds in the general direction of my plate.Luckily for me, I had the foresight to take a Swift MOOC a few months ago in which the course project just happened to involve writing a smartphone app to operate a time machine across Bluetooth. Yes, it seemed rather off-the-wall to me too at the time but it just goes to show there is no such thing as coincidence.

During her time in office the State Department had rules that any personal email systems have to be checked out for security, but Clinton didn't take advantage of this. When two staff members questioned the security of her email system they were told that the server had been reviewed and approved and that they should never to speak of the Secretary's personal email system again.Security fears were realized on January 9, 2011, when Clinton's email server came under attack. Her technical support advisor told operations staff someone was trying to hack us and while they did not get in i didnt [sic] want to let them have the chance to. It was attacked again the next day.The third offender was Ambassador Gration between 2011 and 2012, who also used a private email account for official business. He was politely asked to stop doing so, and when he didn’t, disciplinary charges were filed. Gration resigned before these were pursued.The OIG report isn't good news for Clinton's presidential campaign, since it contradicts several earlier statements made by the candidate and may have a bearing on whether or not criminal charges are brought. Team Clinton has so far declined to comment. It might be time for the warlocks of the Web and brewers of JavaScript to revisit their ever-burgeoning developer wish-lists and sweep away the rubbish.


Researchers from the University of Illinois have looked at how users and Website designers respond to the feature-list, and their study suggests there's a whole lot of kruft that nobody – site owners or end users – are using.Or, as El Reg would put it: your browsers and Web servers are bloating with features nobody wants, and contribute nothing but extra lines of code.As they write at Arxiv: “We find, for example, that 50 per cent of the JavaScript provided features in the web browser are never used by the top ten thousand most popular websites,” the paper states.It'll surprise nobody that at least some of the non-execution of features is down to site ad-blockers and the like, but the end result is: “83 per cent of available features are executed on less than 1 per cent of the most popular 10,000 websites.”A couple of features that the researchers found provide good examples.ALS, “ambient light events”, would let browsers respond to the light level the laptop, phone or desktop is exposed to if anybody used it. Since 14 Websites out of the 10,000 in the study used it, and since it's blocked by 100 per cent of blocking browser extensions, why not kill it off?The Encoding standard would let JavaScript code read and convert between different text encodings if anyone used it, but it's even more unloved than ALS. Nobody bothers blocking Encoding, because only one out of the 10,000 Webmasters was doing anything with it.



Iframes fall into a different category: half of the sites use iframes (because who doesn't love a popup?), but “is prevented from being executed over 77 per cent of the time”.All of this adds to the Web's security woes as well, as the table below (an extract of a much larger table from the study) shows. The study notes, “unpopular and heavily blocked features have imposed substantial security costs to the browser”.The new class of “tech support lockers” rely on tricking users into installing either a fake PC optimiser or bogus Adobe Flash update. Once loaded the malware mimicks ransomware and locks users out of their computers. Unlike Locky, CryptoWall and their ilk it doesn’t actually encrypt files on compromised Windows PCs, however.Jérôme Segura, a senior security researcher at Malwarebytes, said “tech support lockers represent a class of malware more advanced than browser locks and fake anti-virus alerts of the pre-ransomware past.This is not a fake browser pop up that can easily be terminated by killing the application or restarting the PC,” Segura writes in a blog post. “No, this is essentially a piece of malware that starts automatically, and typical Alt+F4 or Windows key tricks will not get rid of it.


One strain of tech support locker employs a subtle piece of social engineering trickery by waiting until a users restarts their computer before confronting users with a fake Windows update screen. Users are told their computers can’t be restarted normally supposedly because of an “expired license key”. Thereafter a screen locks a user out of their computer in an attempt to trick marks into phoning a support number, staffed by scammers.Victims are told that their problems can be resolved, for a fat fee of $250, Malwarebytes discovered.
The particular strain of malware - spotted and documented by independent White Hat security researcher “TheWack0lian” - marks a evolution in tech support scams, Malwarebytes’ Segura warns.“In comparison to fake (but mostly harmless) browser alerts, these Windows lockers are a real pain to get rid of and until you do so, your computer is completely unusable.... This increased sophistication means that people can not simply rely on common sense or avoid the typical cold calls from 'Microsoft'. Now they need to also have their machines protected from these attacks because scammers have already started manufacturing malware tailored for what is essentially plain and simple extortion over the phone,” he writes.



Miscreants have already begun to flog these types of lockers on Facebook, a sign that scams of this type have reached script kiddie level and are therefore likely to become commonplace in future. Previous scams along the same lines, although less sophisticated, include a BSOD ruse that surfaced last September.“There is an entire ecosystem to distribute these tech support lockers, which includes bundling them into affiliate (Pay Per Install) applications,” Segura concludes.More commentary on the scan can found in a post from security blogger David Bisson here.A keyboard combination to disable the tech support locker malware by holding Ctrl+Shift while pressing the S key, was discovered by TheWack0lian. The same white hat discovered hardcoded values for the ‘product key’: “h7c9-7c67-jb” or “g6r-qrp6-h2” or “yt-mq-6w” which may offer a means to recover from infection without paying scammers, at least in the case of this one particular strain of malware.Have you ever bothered to look at who your browser trusts? The padlock of a HTTPS connection doesn't mean anything if you can't trust the other end of the connection and its upstream signatories. Do you trust CNNIC (China Internet Network Information Centre). What about Turkistan trust or many other “who are they” type certificate authorities?

Alors, qu’est-ce que ATS ? ATS a été montré pour la première fois dans iOS 9. Dès lors que le service est activé, ce dernier force les applications à se connecter à Internet en utilisant des connexions HTTPS, qui sont plus sûres que les connexions HTTP traditionnelles. Cela signifie que, lorsque les données sont transférées à partir d’une application à un serveur, celles-ci sont cryptées.Bien sûr, un bon nombre d’applications utilisent déjà ATS — il a été activé par défaut dans iOS 9, mais les développeurs ont pu le désactiver s’ils le souhaitaient. Il était plus que probable que ce ne soit q’une question de temps avant que la fonctionnalité soit obligatoire.Apple n’est pas le seul à s’initier dans la sécurisation des données en ligne. Depuis les révélations de Edward Snowden, beaucoup de choses se sont passées afin de sécuriser les données. D’ailleurs, Apple a pris ceci très au sérieux, comme en témoigne son combat contre le FBI sur l’accès aux iPhone des utilisateurs — Apple encrypte toutes les données sur un iPhone, ce qui signifie que les agences comme le FBI sont incapables d’accéder à ces données.Il y a beaucoup de façons de regarder du contenu à ce jour : vous avez des Smart TV, des petites set-top-box, ou encore des consoles de jeu. Mais, le Chromecast de Google est un dispositif extrêmement populaire, à tel point qu’il a cannibalisé 35 % du marché des lecteurs de flux multimédias en 2015.


Quand le géant de la recherche l’a lancé en 2013, le petit dongle HDMI a fourni un moyen pas cher et facile de pousser des films et des séries TV depuis vos applications préférées afin de les « caster » sur votre téléviseur. Cela a été une réelle révolution, et a été l’un des meilleurs produits en 2013.Maintenant, le Chromecast est de retour avec un tout nouveau look, quelques nouvelles fonctionnalités, et une toute nouvelle application qui promet de trouver ce que vous voulez plus facilement que jamais. Mais, ce dongle de deuxième génération qui se vante de nouveaux ajouts vaut-il la peine d’être acheté si vous avez le modèle de première génération ?Concernant sa conception, le Chromecast de nouvelle génération a plus ou moins reçu une refonte totale. Maintenant, le dongle ressemble moins à un bâton, et est désormais un petit disque avec un court câble flexible HDMI. C’est un grand changement par rapport au précédent opus, et tandis que le Chromecast arrive dans de nouveaux coloris clinquants (Citron et Corail), la nouvelle forme rend le dongle extrêmement esthétique. En effet, ce dernier est beaucoup plus petit, et le câble du connecteur HDMI va se contorsionner, lui permettant de se faufiler dans des espaces serrés où les ports sont difficiles à atteindre.



L’aimant à l’arrière de la petite rondelle permet de maintenir le câble, et il vous permet d’apposer le dispositif soit sur le câble lui-même ou à l’arrière de votre téléviseur — tant que le châssis de celle-ci soit métallique. Comme l’original, le Chromecast va pouvoir être alimenté par une prise standard, ou par un port USB compatible à l’arrière de votre téléviseur.Vous trouverez le logo Chrome fièrement décoré sur le dessus. Parlons du disque lui-même. Il est petit (51,9 x 51,9 x 13.49 mm), et il se glisse discrètement dans la paume de votre main.À l’intérieur du petit disque, un trio d’antennes permet au dispositif de tirer le meilleur de la connectivité Wi-Fi. Le Chromecast est désormais compatible avec la connectivité Wi-Fi 802.11ac, et il va se connecter à des points d’accès en 5 GHz. Toutes ces améliorations sont destinées à améliorer la stabilité de la connexion, et l’expérience du streaming.Sur le papier, il est difficile de réellement mesurer l’amélioration apportée à la connectivité, puisque je n’ai jamais rencontré de problème particulier avec ce périphérique. Pourtant, ceux qui ont rencontré quelques difficultés par le passé devraient voir au moins une certaine amélioration.

Lorsque Google a dévoilé le Chromecast à San Francisco, le géant de la recherche a également affirmé que le dispositif offrira une meilleure qualité vidéo et audio, avec moins de mémoire tampon pour une meilleure expérience globale. Mais à part une forte emprise sur votre signal Wi-Fi, il n’y a pas de véritable changement dans la qualité de streaming.Le nouveau Chromecast offre une qualité vidéo 1080p, tout comme son prédécesseur, et (pas de surprise à 39 euros), il ne supporte pas le contenu 4K UHD, ce que d’autres périphériques offrent, notamment le nouveau Amazon Fire TV et le Roku 4.Une fois que vous avez alimenté l’appareil et branché ce dernier sur le port HDMI de votre téléviseur, il sera temps de passer à travers le processus d’installation du nouveau Chromecast. Le processus de configuration prend pas plus de cinq minutes, et la plupart de celles-ci sont utilisées pour télécharger l’application Chromecast soit depuis le Google Play Store ou l’App Store d’iOS — bien que vous pouvez également utiliser un PC ou un Mac pour streamer du contenu sur le Chromecast. Vous serez invité à connecter le Chromecast à votre réseau sans fil. Le tour est joué !


Chromecast 2015 : vous allez pouvoir streamer de nombreux contenusChromecast 2015 : vous allez pouvoir streamer de nombreux contenus
Les nouvelles touches apportées au design sont agréables, mais si l’on doit décortiquer ce qu’il y a de nouveau avec le Chromecast, cela se passe au niveau de l’application. Contrairement à un grand nombre d’autres entreprises de haute technologie, la nouvelle version de l’application de Google fonctionne avec tous les appareils Chromecast, y compris les nouveaux et les anciens — et le nouveau Chromecast Audio. En dehors de la famille des Chromecast, l’application offre une surabondance de nouvelles fonctionnalités qui en font une bonne raison d’en acheter un.L’application est divisée en trois grandes catégories. Dans l’une d’elles, vous allez retrouver une sélection de titres de toutes les applications que vous avez déjà sur votre smartphone. Ensuite, la section « Appareils » vous permet de basculer facilement entre vos multiples Chromecast, que ce soit vidéo et/ou audio. Le dernier volet permet de télécharger les applications, qui, comme vous l’aurez deviné, sont compatibles avec un Chromecast.



Dans les paramètres de chaque périphérique, il est désormais facile d’ajouter vos propres photos (backdrop) à partir des services tels que Flickr, Facebook, et vos comptes Google pour mélanger avec les magnifique photos récupérées sur le net que le Chromecast met en fond d’écran. En effet, lorsque vous n’êtes pas en train de streamer du contenu sur le Chromecast, il entrera dans un mode économiseur d’écran qui permet d’afficher de multiples sources d’informations.Une nouvelle fonctionnalité plutôt cool de l’application Chromecast est l’ajout de la recherche multi-plate-forme, permettant de rechercher des contenus par la saisie textuelle ou vocale depuis l’une de vos applications de streaming Chromecast. La recherche fait une énorme différence quand elle est accessible à votre convenance — surtout quand vous êtes sur le dense catalogue de Netflix. Et, la nouvelle fonctionnalité permet (enfin) au Chromecast de mieux rivaliser avec la horde des plus coûteuses set-top-boxes et autre TV Stick d’Amazon, Roku ou Apple.En cliquant sur le micro, vous allez rechercher par la voix ou par une saisie manuscrite, soit des séries TV ou des films, des genres, comme des films d’horreur ou de science-fiction, ou encore le nom de votre acteur favori. Une fois le contenu affiché, un simple clic sur le titre vous redirige directement vers l’application appropriée. Évidemment vous devez toujours contrôler la lecture à travers l’application elle-même, mais c’est néanmoins un grand pas en avant.

Akku für HP Compaq HSTNN-DB11

Sion heißt das Elektrofahrzeug des Münchner Start-up-Unternehmens Sono Motors. Das Besondere daran: Am Fahrzeug angebrachte Solarzellen laden die Batterie. Insgesamt 330 Solarzellen verbaute das Unternehmen in die Karosserie des Sion. Heckklappe, Motorhaube, Dach sowie Türen sind mit Zellen bedeckt, die wiederum mit einer Schicht aus Polycarbonat überzogen sind.


Der Sion von Sono Motors ist mit Solarzellen bedeckt.

Zum Schutz vor schädlichen Umwelteinflüssen sind die Solarzellen in eine Schicht Polycarbonat eingebettet.

Sono Motors

Sowohl im Stand als auch während der Fahrt können die Solarzellen so die Batterie aufladen, wodurch das Fahrzeug laut Unternehmen bis zu 30 km pro Tag mehr zurücklegen kann. Insgesamt kommt man im Viersitzer bei voller Batterie rund 250 km weit. Zusätzlich lässt sich die Batterie mittels eines bidirektionalen Ladegeräts sowohl über das konventionelle Stromnetzt laden als auch unabhängige Stromquelle nutzen. So können beispielsweise kleine elektronische Geräte mit bis zu 2,7 kw Energie versorgt oder sogar andere Elektroautos über einen Typ-2-Stecker mit 7,6 kW geladen werden.


Rund 16.000 Euro soll der Sion kosten, jedoch müssen Käufer sich dann entscheiden, ob sie die Batterie für zusätzliche 4000 Euro kaufen oder für einen noch nicht spezifizierten Preis mieten. Zu den Features des Autos zählen auch eine Smartphone-App und Mobilitätsservices. Die App ermöglicht es, so die Idee der Entwickler, den Sion mit anderen Menschen zu teilen (Carsharing) oder Powersharing zu betreiben, also Energie aus der Batterie anbieten. Zusätzlich können Besitzer des Sions Mitfahrgelegenheiten anbieten (Ridesharing).



Gegründet wurde Sono Motors im Januar 2016. Zur Finanzierung ihrer Idee startete das Unternehmen im Juli 2016 eine Crowdfunding-Kampagne und sammelte so bis September 2016 über 700.000 Euro zur Umsetzung ihres Elektrofahrzeugs. In verschiedenen Städten bietet Sono Motors ab Mitte August Probefahrten an. Die Serienproduktion soll dann im zweiten Quartal 2019 beginnen, sofern 5000 Vorbestellungen eingehen. Momentan liegt die Zahl der Vorbestellungen bei rund 1500.


Wer überprüfen will, ob seine Fernbedienung Signale aussendet, kann dies ganz einfach mit der Handy-Kamera überprüfen. Dazu muss diese aktiviert werden, im Anschluss wird die Vorderseite der Fernbedienung auf die Linse gerichtet und eine beliebige Taste gedrückt. Im Display des Telefon kann nun das Leuchten der Infrarot-Dioden gesehen werden, sofern die Fernsteuerung tatsächlich richtig arbeitet. Das ist beispielsweise auf dem obigen Bild zu sehen, das mit einem Microsoft Lumia 550 aufgenommen worden ist. Im unteren Bild ist der gleiche Vorgang mit einem älteren Samsung-Smartphone aufgenommen worden.


Wie bereits erwähnt, gibt es aber durchaus Kameras, die die Überprüfung erschweren. Das ist auf dem folgenden Bild zu sehen, das mit einem Apple iPhone 6s erstellt wurde. Das Leuchten der Dioden ist bei diesem Telefon kaum zu erkennen, weshalb es mit dem roten Kreis markiert wurde.


Das klappt aber in der Tat nur dann, wenn auch Infrarot zur Übermittlung der Steuerbefehle verwendet wird. Bei einigen Steuerungen ist das nicht der Fall, etwa bei Amazon Fire TV. Hier arbeiten die älteren Bedienungen mit Bluetooth, die neueren per WLAN, weswegen keine optische Erkennung möglich ist.


Update, 05.07.2017, 14:44 Uhr: Bei den obigen Bildern wurde eine Universal-Fernbedienung von Medion (Lumia 550) sowie eine Logitech Harmony (Samsung und iPhone) verwendet. Ein weiterer Test mit der Fernbedienung des Sky-Festplattenreceivers hat ergeben, dass bei dieser das Leuchten der Infrarot-Dioden mit dem iPhone 6s nicht erkennbar ist, mit dem Lumia 550 hingegen ganz schwach. Letztlich sollte das aber kein Problem sein, denn bei Sky ist eigentlich immer der Receiver die Fehlerquelle, und nicht die zuverlässige und extrem sparsame Fernbedienung. Allerdings zeigt dieser Fall noch einmal, dass der Test stark von der Kombination aus Steuerung und Kamera abhängig ist und längst nicht immer zuverlässig funktioniert.


Smartphones mögen weder sommerliche Hitze noch die derzeitigen Minusgrade. Manche Geräte schalten sich sogar von selbst ab, wenn es ihnen zu eisig wird, obwohl der Akku eigentlich noch gar nicht leer ist. In den mobilen Telefonen sind Lithium-Ionen-Akkus verbaut. Am besten funktionieren sie bei Temperaturen von 10 bis 25 Grad Celsius. Apple gibt für seine iPhones beispielsweise eine Betriebstemperatur von 0 bis 35 Grad Celsius an.



Lithium-Ionen-Akkus sind Batterien, in denen Lithium-Ionen die elektrische Ladung in einer Elektrolytflüssigkeit zwischen Kathode und Anode transportieren. In elektronische Geräte werden sie seit Anfang der 1990er Jahre verbaut. Der japanische Technologiekonzern Sony hat sie zur Marktreife entwickelt.


Kälte verlangsamt die elektrochemischen Prozesse

Ist allerdings die Umgebungstemperatur zu niedrig oder zu hoch, verschleißt die Batterie deutlich schneller als üblich. Denn Kälte verlangsamt die elektrochemischen Prozesse, weil die Elektrolytflüssigkeit zäher wird. Und das erhöht wiederum den Innenwiderstand. Wenn nun das Handy viel Strom braucht, führt das dazu, dass die Spannung des Akkus sinkt und es zu einer Tiefenentladung kommt, die den Akku schädigt. Das vorsorgliche Selbstausschalten will das verhindern.


ANZEIGE


Das Phänomen kann vor allem ältere Geräte mit schon häufig wiederaufgeladenen Stromspeichern treffen. Zwar verkraften Lithium-Ionen-Akkus zwischen 1000 und 3000 Ladezyklen ohne Einbußen bei der Leistung. Die Batterien altern aber dennoch. Schäden in der Struktur sorgen dann dafür, dass die elektrische Spannung bei Kälte abrupt sinkt. Ist es dagegen sehr heiß, beschleunigt das die Abläufe im Lithium-Ionen-Akku. So lassen Temperaturen von 40 Grad Celsius ihn bis zu dreimal schneller altern.


Wer bei Minusgraden sein Smartphone mit nach draußen nimmt, sollte es nah am Körper tragen und mit Headset telefonieren.

Battery for HP ProBook 4540s

The vulnerabilities in question are CVE-2016-4957 (another vulnerability in Crypto-NAK found by Cisco), and from Red Hat there's CVE-2016-4953 (an authentication bug), CVE-2016-4954 (server packet spoofing), CVE-2016-4955 (autokey association reset) and CVE-2016-4956 (a broadcast interleave bug).This Damn War “What’s the smallest fire I could start to be noticed, but not so big that I risk burning down the building?” is one of the stranger thoughts to have entered my head, in many years of working in IT. No, I'm not a closet pyromaniac, so why was I entertaining such thoughts?I had found myself stuck in a data centre on a Sunday afternoon and by that point, I’d been in there for over two hours with no sign of rescue. That shouldn’t have been the case, of course, but a series of unfortunate events had led me down that road.The data centre in question was undergoing an enormous refurbishment, and the rack I was working on was one of the last stragglers in an aged hall that was waiting to be decommissioned. When I arrived, the on-site team were very conscientious in pointing out open floor tiles and various other construction-related trip hazards; unfortunately, the contractors had been rather less meticulous.


I completed the work I needed to, then packed up my bag to leave. When I got to the exit however, my access card wouldn’t unlock the door. After a few frustrated swipes I tried the emergency door release button, also to no avail. Following some rather pitiful shoulder bunts against the door, to see if the release was working but the door itself was physically stuck – it wasn’t, it hurt – I conceded that the contractors must have fouled up the access control system somehow.“Not a problem,” I thought to myself, and picked up the telephone on the wall adjacent to the door, normally a direct line through to the operations centre. The line was dead, another casualty of the building work.“Still nothing to worry about,” I mused, and started waving my arms in front of the CCTV camera above the door to get someone’s attention.I jumped around in front of that camera for far longer than I’d care to admit, before I resigned myself to the fact that nobody was watching (or rather, able to watch) and sat down on the floor to take stock of my options.I first reached for my mobile phone which was almost fully charged, but had no signal in the metal sarcophagus of the data centre’s innards. Next up was my laptop: I could grab a network cable, plug directly into the network switch in my rack, and contact the outside world to achieve my freedom. Unfortunately, that was my third stop of the day and I’d already worn my laptop’s meagre battery down… and the power supply was on my desk at home. There wasn’t even a KVM trolley in the hall to use one of our servers to call for help, another casualty of the decommissioning process.



Deflated, I sat on the floor, and wondered how long it would take for someone to notice I was gone. I hadn’t given my wife an ETA for arriving home and as far as my colleagues were concerned this was a “pop in on my way past” flying visit, so they wouldn’t be expecting to hear from me again. By this point, I’d been in there for well over an hour and nobody had been to check on me; I was starting to get worried.What got me really worried was when I couldn’t open the fire door at the back of the hall. I could depress the release bar, but there was some construction detritus behind the door that meant it simply wouldn’t budge. Cue more pathetic shoulder charging, to no avail.I hammered on the fire door for a while and shouted myself hoarse, but nobody heard, so I tried the main door. Shouting for help turned into profanities, which turned into pleading and plaintive wails, but no help was forthcoming.Again, I sat on the floor and stewed for a while, and by the two-hour mark I was starting to feel desperate, which probably explains the (admittedly, very poorly-thought out) ‘start a small fire’ plan; quickly shelved, when I realised the fire alarm didn’t go off when I tried the door.


As I began to contemplate a night in my personal air-conditioned hell, a thought occurred to me: the fire alarm might have been yet another casualty of building works, but it wasn’t the only kind of monitoring.I ran over to my rack and pulled a couple of redundant power cables; not serious enough for an outage, but enough to generate some alerts from our own monitoring. I replaced them and did the same with more servers – lather, rinse and repeat – until the constantly flapping monitors caused one of my team to ring the data centre, to ask them to eyeball our rack and check for ‘power problems’.All told, I’d been trapped in that data centre for less than three hours, but even so when that door did finally open I felt like Shawshank Redemption’s Andy Dufresne. Lenovo is warning users to uninstall its Accelerator support application after it was revealed to have what it says are serious interception vulnerabilities.The company is one of five vendors caught pre-installing dangerously-vulnerable OEM software.


Duo Security researcher Mikhail Davidov reported the holes that would allow eavesdropping attackers to tap into Accelerator's unencrypted update channels to compromise users."A vulnerability was identified in the Lenovo Accelerator Application software which could lead to exploitation by an attacker with man-in-the-middle capabilities," Lenovo says."The vulnerability resides within the update mechanism where a Lenovo server is queried to identify if application updates are available."Lenovo recommends customers uninstall Lenovo Accelerator Application."Unencrypted update channels open an avenue for attackers to among other efforts push malware masquerading as software patches. It is limited in that it requires affected users to connect to malicious or open wireless networks to be exposed.Only those Lenovo machines with Windows 10 pre-installed sport the exposed app.The Lenovo Accelerator Application is used to speed up the launch of Lenovo applications and was installed in some notebook and desktop systems preloaded with the Windows 10 operating system.



Laptops from Acer, Asus, Dell, and HP were also tested and found to have a dozen vulnerabilities. All contained at least one hijacking flaw, most of which are easy to exploit.Lenovo says some 46 notebook and 25 desktop lines are affected, including its top end Y700 gaming laptop, IdeaCentre all-in-one desktops, and Yoga flip netbooks.It follows the 2014 shelling of Lenovo after it bundled the Superfish adware which used a trusted root certification authority certificate that allowed attackers to spoof HTTPS traffic. AMD has officially torn the wraps off its seventh-generation processors for laptops and notebooks. These are, we're told, shipping in volume in gear from Acer, Asus, Dell, HP, and Lenovo.As warned in April, and announced today at Computex 2016 in Taipei, the CPUs use AMD's Excavator architecture as found in Carrizo.AMD's new “Bristol Ridge” seventh-gen family features 35W and 15W versions of AMD's FX, A12 and A10 processors, and the “Stoney Ridge” gang includes 15W A9, A6 and E2 chips. The list of Mini Chipzilla's seventh-gen CPUs is here.


Meanwhile, the $199 Radeon RX 480 graphics processor has popped up, powered by the Polaris architecture, and is aimed at VR geeks. Computers from many of the biggest PC makers are riddled with easy-to-exploit vulnerabilities in pre-loaded software, security researchers warn.The research from Duo Security shows that bloatware is not just a nuisance that causes a lag in system boot-up, but a security risk. Laptops from Acer, Asus, Dell, HP and Lenovo all have at least one security vulnerability that can lead to a full system compromise. Most of the vulnerabilities would be straightforward to exploit even for technically unsophisticated hackers, according to Duo Security.Lenovo copped an enormous amount of flack after it began bundling Superfish adware with some of its computers in September 2014. Superfish adware was installed on some Lenovo PCs with a trusted root certification authority (CA) certificate, allowing an attacker to spoof HTTPS traffic.A machine with Superfish VisualDiscovery installed will be vulnerable to SSL spoofing attacks without a warning from the browser, as US CERT warned around the time the scandal broke in early 2015.

Akku für Apple A1008

Das Elektroauto lädt sich teilweise durch Sonnenenergie selbst auf. Im Dach, in der Motorhaube, im Heck und in der gesamten seitlichen Karosserie befinden sich monokristalline Siliziumzellen, die unter einer acht Millimeter dicken Polykarbonat-Schicht angebracht sind. Dieses Material ist nahezu unzerbrechlich und witterungsbeständig. Insgesamt 7,5 Quadratmeter der Außenfläche des Wagens nehmen sie ein und laden, wenn das Auto abgestellt wird. Der Sion kommt mit seinen Batterien auf eine Reichweite von bis zu 250 Kilometern. An sonnenreichen Tagen sollen die Solarzellen nach Herstellerangaben Strom für bis zu 30 zusätzliche Kilometer erzeugen können. Bei bewölktem Himmel sind es immerhin noch 15 Kilometer extra.


Solarauto und Stromgenerator in einem


Das bidirektionale Ladesystem (biSono-System) des Sions macht aus dem Elektroauto einen mobilen Stromspeicher. Elektronische Geräte lassen sich an den Sion durch eine von außen zugängliche Steckdose anschließen. Mittels eines Haushaltssteckers für alle gängigen elektronischen Geräte (230 Volt) mit bis zu 2.700 Watt ist die Stromentnahme möglich. Mit einem Output von 6,6 Kilowatt ist er sogar in der Lage, andere Elektroautos zu laden. Über eine App kann man Strom, der nicht benötigt wird, zur Weitergabe anbieten. Außerdem soll man über die Applikation den Sion als Mitfahrgelegenheit anbieten können oder den Wagen vermieten.


Spezielles Moos filtert Luft


Viel Wert auf Nachhaltigkeit legten die Entwickler auch bei der Gestaltung des Innenraumes. Sie integrierten in die Armatur Moos, das als natürliche Klimaanlage fungieren soll. Es sorgt für Luftfilterung und bedarf keinerlei Pflegeaufwand. Das Moos zieht das Wasser, das es benötigt, aus der Luft und reguliert so gleichzeitig die Luftfeuchtigkeit im Innenraum. Die Mikrostrukturen des Mooses binden Feinstaubpartikel aus der Luft, so atmet man selbst auf stärker befahrenen Straßen frischen Sauerstoff ein. Außerdem schützt das Moos nach Brandschutzklasse B1, da es feuerhemmend ist.



Dank seines einzigartigen Instandhaltungssystems reSono erweist sich die Wartung des Sion als kostengünstig und unkompliziert, betont der Hersteller. Das Werkstattbuch ist kostenlos auf der Website von Sono Motors einsehbar. Ersatzteile sollen preiswert online nachbestellbar sein. Auch ohne große Fachkenntnisse lassen sich einfachere Arbeiten mit Hilfe von Erklärungsvideos sowie eines Anweisungskatalogs selbstständig verrichten. Die Instandhaltungskosten halten sich so im Rahmen und eine lange Lebensdauer ist gewährleistet.


Geringer Preis macht Elektromobilität alltagstauglich


Der Sion soll im Vergleich zu anderen E-Autos auf dem Markt deutlich preiswerter sein. Bei der Präsentation des Solarautos gab der Hersteller bekannt, dass es nicht wie ursprünglich angekündigt die Version Urban (12.000 Euro) und Extender (16.000 Euro) geben wird, sondern nur den Extender. Der Wagen soll mit einer monatlichen Batteriemiete oder einem einmaligen Batteriekauf in Höhe von 4.000 Euro verfügbar sein. Frühestens 2019 wird die Auslieferung beginnen. Dafür sollten allerdings 5.000 Vorbestellungen vorliegen.


Der ETM Verlag verleiht in Zusammenarbeit mit der Dualen Hochschule Baden-Württemberg (DHBW) Ravensburg zum zweiten Mal den Deutschen Telematik Preis. Die Nominierten und damit die jeweils ersten drei Platzierten der ersten Runde stehen fest. Ihre Anwendungen werden jetzt im Labor getestet, um den Gewinner in den neun Kategorien zu ermitteln. Alle Leistungen der Teilnehmer werden in den fünf Klassen Systemeigenschaften, Ortung und Kartendarstellung, fahrzeugbezogene Funktionen, fahrerbezogene Funktionen und Geschäftsprozessmanagement untersucht.


OEM-Telematik setzt zunehmend auf Apps

In der Kategorie Hersteller-Telematik beziehungsweise OEM-Telematik sind Daimler Fleetboard, Scania One und ­Volvo Dynafleet nominiert. In der ersten Runde stellte sich heraus, dass Fleetboard besonders beim Geschäftsprozessmanagement herausragt. Mit Fleetboard Disposition und Fleetboard Messaging hat das Unternehmen eigene Funktionen im Programm, um die Fahrzeuge auch zu disponieren.

Hinzu kommt ein App Store, in dem sich die Nutzer spezialisierte Programme herunterladen können. Bisher wurden gerade diese Features eher vernachlässigt. Die Hersteller konzentrierten sich mehr auf ihre Kernkompetenzen, die Fahrzeug­daten. Daraus konnten sie überdies sehr gut die Fahr­weise der Fahrer analysieren. Damit punkten Scania und Volvo. Zudem sticht Volvo mit Dynafleet auch bei den Ortungs- und Kartenfunktionen heraus. Das wird ein spannender Kampf um die Trophäe.



Das größte Feld mit acht ­Lösungen im Wettbewerberfeld bildeten die Nachrüst-Lkw-Telematiken für Komplett-/Teilladungen. Dort setzten sich nach der ersten Runde Arealcontrol, GPS over IP und Tom Tom ­Telematics durch. Die Drittanbieter sind auf den ersten Blick besonders stark bei den Ortungsfunktionen und der Karten­darstellung. Hier kommen die Nominierten teilweise auf mehr als 90 Prozent. Wer sich hier durchsetzen will, musste aber auch in den anderen Unter­suchungsfeldern starke Funktionen nachweisen. Arealcontrol konnte sich hier mit dem Arealpilot 720 MDT und dem eignen Telematik­portal durchsetzen, GPS over IP kommt mit dem GPS-Auge und dem GPS-Explorer in die nächste Runde und Tom Tom Tele­matics schafft es mit dem Pro 8275 in Verbindung mit Link 510 und dem Portal Webfleet.


Im Stückkgut braucht es andere Funtionen

Wie wandelbar die Lösungen der Drittanbieter sein können, zeigt sich in der Kategorie Nachrüst-Lkw-Telematik für Stückguttransporte. Im Vergleich zu Komplett- und Teilladungen müssen die Lösungen im Stückgutbereich differenzierte Funktionen anbieten, um die Ladung immer im Blick zu behalten. Die gleichen Unternehmen haben teilweise auch hier die Nase vorn, obwohl besonders das Geschäftsprozess-Management beim Stückgut höher gewichtet wird.

Battery for Lenovo ThinkPad SL500

NASA has deliberately set a fire inside a Cygnus spacecraft, after detaching from the International Space Station (ISS) for safety reasons.The capsule is carrying the Spacecraft Fire Experiment, which has ignited a variety of materials to study how they burn and spread in microgravity. The purpose is to help protect future missions from the possibility of burning up while the nearest fire department is millions of miles away.NASA reports that the experiment is burning nicely and has traveled 1,000 miles in space so far. When NASA is sure it's received all the data it can from the tests the whole lot will be pushed earthward for fiery disposal. It is with incredible sadness that El Reg must report that Lester Haines, one of our finest story-tellers and an all-round good bloke, passed away on Monday. We have published his obituary, The Life and Times of Lester Haines.Lester, who was 55, died of a heart attack at his home in Spain. He will be cremated on Friday 17 June.Readers will know Lester for his biting wit, his piloting of the Special Projects Bureau – including the PARIS and LOHAN projects – and his wonderful recreations of real-world events through the medium of PlayMobil.


Lester joined The Register in 2000 to manage merchandising and photography but grabbed the nearest laptop and wrote his first article in September that year, about one of our own defecting to the dark side – or PR, as it is otherwise known.Among the 7,300 stories Lester produced for El Reg were regular features including Logo Watch, Strategy Boutique, Rise of the Machines, and Flame of the Week.It didn't get any airtime at the big opening day of the annual Apple Worldwide Developers Conference (WWDC), but excitement is building around Apple's next-generation file system.Early specs show the system will bring your hard drive into the modern era, most notably by supporting native encryption. It will also time-stamp files by nanoseconds (rather than seconds), making it better for modern databases, and take snapshots of the file system, massively reducing the time needed to make backups.Other interesting features include crash protection, space sharing – which will enable much more flexible partitioning – optimization for solid-state hard drives, and a better system for cleaning up deleted files.In short, the new Apple File System (APFS) can be expected to bring significant advances in speed and efficiency, and the updating of Apple's file sharing technology, which hasn't changed in nearly 20 years (others, of course, have developed more modern systems that are now 10 years old).



APFS' preliminary information has been released to developers, and sessions on it will take place this week at WWDC. It is scheduled to ship sometime in 2017, meaning that the company may be able to boast big performance improvements in its products toward the end of that year. It is designed to work with all of Apple's operating systems – iOS, watchOS, tvOS and macOS.There is still a lot of work to be done, however. It is not currently possible to start your computer directly with the file system, and it doesn't work with Apple's current encryption and archiving systems – presumably because it is intended to replace them.The file system is also case-sensitive and that apparently cannot be disabled, which will lead to all sorts of knock-on compatibility issues. Yep, you will have to buy more Apple gear: a new watch to go with your new phone to sync with your new laptop. Apple is always looking after that bottom line.Support documents published by 9to5Mac indicated the platform will be rebranded macOS, the name of the Mac’s original OS when it launched in 1984, one of four Apple platforms. The others are watchOS, tvOS and iOS.


9to5Mac later updated its story to say Apple had changed its pages back to read Mac OS X.The workstation NeXTSTEP 1.0 was originally unveiled in 1988, before going cross platform.Apple acquired NeXT in a reverse takeover that brought Steve Jobs back to the company he founded, and the platform was revamped extensively before launching as Mac OS X in 2001. Presumably, Apple now reckons it's so long (15 years) since the last release of the original MacOS, no confusion will be created.USB-C and Thunderbolt are the last mainstream connections devices will need to the outside world, according to analyst firm ABI Research.The company's new Device Connectivity Report predicts that by the year 2020 “Almost half of the smartphones and 93% of laptops will include USB Type-C connectivity.” In coming years we'll also see gadget-makers will offer “fewer connectivity types and ports per device as the industry steadily transitions toward wireless solutions and cable-free devices.”ABI analyst Andrew Zigani opines that “USB-Type C and Thunderbolt 3.0 will be the last major physical ports to gain major significance and mainstream traction.”Next up? Wi-Gig, aka 802.11ad, which has already made it on to some business laptop vendors' feature lists for 2016 and is expected to become more common in coming years. WiGig can handle video traffic to displays or general purpose data. WiGig Docks are starting to emerge, but before long it's expected the standard will appear in devices like televisions, projectors and monitors.



Of course there are untold millions of such devices out there, most of which are good for years more use. Further, nobody is suggesting wireless charging pads are going to become so ubiquitous that we can all do without mains connections. So chances are gadgets will need at least one physical port for the foreseeable future.But Zignani reckons there's no need for the industry to consider mainstream connectors beyond USB-C and Thunderbolt 3.0. And seeing as Intel last year decided it's happy for the USB-C port to handle Thunderbolt traffic, rather than its own physical port design, we're on track for a single standard hole for most portable devices any year now.Special report In Australia and New Zealand, hackers are doing it for themselves by creating vibrant security conferences that run on their own terms and actively avoid the corporate-speak and fear-mongering that characterises so many vendor-led events.These conferences, or cons, are booming and showcase security skills that rival the best the global security industry can offer.The hacker-run conferences are nothing like commercial technology confabs: vendor pitches are universally banned, so are trade show booths. Bars replace bain maries full of conference casseroles and black metal-inspired custom shirts are the de facto uniform.At these events hackers reveal holes in the world's most popular technology and public transport systems to a soundtrack of sweeping moans of derision, laughter, and, for some cons, bursts of on-stage pyrotechnics.Most hacker presenters follow the modern line and push the companies they hack to fix holes ahead of their on-stage disclosures, yet blasé promises to fix earn retribution as zero-days are still dropped.
