 Battery for Acer Aspire one 532 Alerter l'administrateur Recommander à un ami Lien de l'article 

Although detailed pricing has not been announced, the company said that the Idol 4 series will be available from April 2016, at prices from €279 to €449.Alcatel Plus 10 Next up from Alcatel is a Windows 10 2-in-1 tablet/laptop. The Plus 10 is a 10.1 device with a quad-core 1.92GHz Intel Atom x5-Z8350 chipset. The keyboard is detachable and includes a SIM slot for LTE (4G wireless) connectivity so you can use it as a wifi hotspot for up to 15 users.You also get basic cameras front and rear, 32GB internal storage, 2GB RAM, MicroSD slot, USB and HDMI ports. The Plus 10 is not the slimmest of devices but weighs only 850g, and battery life of 8 hours light usage is claimed. The model on display in Barcelona felt a bit plasticky but its light weight is a benefit.The Plus 10 will be available from June 2016, priced from €379, according to the presentation in Barcelona.

The company is very bullish on Windows, according to VP and chief marketing officer Dan Dery. The Plus 10 joins the Fierce XL Windows 10 smartphone, released earlier this year in the US, and the Pixi 3 8-inch Windows 10 tablet announced at CES in January and set for availability in April 2016. The Pixi 3 is an ARM-based device running Windows 10 Mobile, whereas the Plus 10 runs full Windows and is the first Alcatel device with an Intel chipset.Why do a Windows 10 device? There is a business market but there is also a very good consumer market, Dery told El Reg. A market that is very familiar with Windows. Having a laptop at home that can be detached as a tablet makes a lot of sense.MWC16 HP Inc has unveiled a big bet re-entry into the handheld device market, banking on enterprise’s attachment to the Windows ecosystem to blur the memory of its previous forays and retreats into the space.The vendor will unveil its Elite x3 phablet at MWC, a six inch-high, 7.8mm thick phablet, along with a desktop dock to connect with a big screen and proper corporate networks, and a mobile extender with full size keyboard and 12.5 inch screen.The device cops a Qualcomm Snapdragon 820 processor, meaning it will not be a true Wintel device, but it will run on Windows 10. It packs 4GB of RAM, 64GB of internal memory and will take SD cards of up to 2TB - once they actually hit the market.And how much will all this cost? We don't know yet, with pricing due to be released shortly before its expected summer release.Michael Park, VP and GM for mobility and retail solutions at HP Inc, claimed the x3 is “the one device that is every device...we are basically covering desktop, notebook and phablet use cases with one product”.

He said that while most mobile/handheld vendors were pushing into the enterprise as “a marketing continuum” of their consumer product lines the X3 was an unapologetically commercial enterprise product “designed for a commercial lifecycle which is two to three years.”This industrial grade ethos extends to dual SIM support, claimed all-day battery life, dual biometrics, 8MP front facing camera, active noise cancellation and B&O optimised audio so that you can really appreciate the hold music while waiting for your conference call to start.The x3 is IP67 tested, meaning it can take a four-foot fall, and will operate under water for 30 minutes before failing. (Though if that latter use case is relevant, perhaps you need to reconsider who you’re doing business with.)Needless to say, Park also describes the device as “beautiful”. Nevertheless, despite all this status symbol box ticking, HP’s key selling point will likely be its compatibility with existing enterprise legacy systems.Park said the world doesn’t quite seem to have twigged that with Windows 10 for “the first time in the history of Microsoft that all devices have converged to the common Windows kernel.”While he had no illusions that the consumer world is unlikely to shift ecosystems any time soon, “In the world of commercial though when you go talk to a CIO and ask ‘what you do you use to drive productivity in your enterprise, to secure your back-end or to run your servers,' Microsoft is still the name in the game.”

“The average Fortune 500 company has 3,500 bespoke apps that they’ve written over the last 20 to 30 years, all on .Net, all for PCs, and those have to be moved to a mobile world if that is how people are going to work.”“I think what the market doesn’t see that’s going to happen is the ability to use Continuum in Windows 10 to now drive a new type of application where you write it once and it runs on a desktop, a phone, a Surface hub, a workstation without having to re-write code will present a massive TCO and value proposition for IT moving forward.”If enterprises opted for iOS and Android for their sub-notebook needs, he added, “you have to maintain all that code separately from everything you’ve done in the last 20 years and you have to carry it forward in terms of integrating those things as the underlying OSes change.The TCO implications for this “will become more evident once Windows 10 gains more adoption,” he said.Needless to say, HP has gained vocal support from Microsoft for the launch. The devices will also come bundled with the Salesforce One - when it is docked, it will kick into the full Salesforce One dashboard. Park said it was working with other ISVs on vertical apps, while HP will provide its own app catalog, dubbed Workspace.

What will really underpin the device’s success after its summer launch is whether HP can persuade corporates to buck their users' consumer-based prejudices, and overlook HP's own form in this sector.The company’s false starts in handheld devices and phones include mid-noughties Windows Mobile devices under the iPaq brand it inherited from Compaq. Yes, we're not sure what happened to them either.The company bought the seminal handheld firm Palm in 2010 for $1.2bn, then said it was only after the operating system, WebOS, before losing interest altogether during its minor meltdown under its short-lived CEO Leo Apotheker the following year. Much of the former Palm, and iPaq, IP was sold off in 2014 to... Qualcomm. Runtime Readers' tales of very old computers keep rolling in, so we'll keep rolling them out at you. We even gave ourselves a name for this silliness: Runtime.The last week's most interesting inbox insertion was news of a Tandy 102 that's still alive and kicking and helping reader “Ed” to stay alive and kicking too.The 102 is a member of the TRS-80 family, the PC that Tandy Corporation introduced in 1977. The TRS-80, known as the “Trash Eighty” by snooty Commodore 64 fanbois, started life as a desktop computer. Several models adopted the all-in-one shape made popular by the Commodore Pet and a “luggable” even made it into the range.

Tandy eventually decided that the thrusting young executive types of the early 1980s wanted something rather more portable when they took the elevators to the upper reaches of Nakatomi Plaza, so acquired the rights to Japanese company Kyocera's Kyotronic 85. The anglosphere's version was launched as the TRS-80 Model 100 and gave users a full keyboard and eight-line, 40-characters per line screen in glorious grey-on-grey.A 2.4MHz Intel 80C85 hummed along inside, sipping so little power that the machine was powered by a quartet of AA batteries. An on-board backup battery made sure the data in the machines' RAM – you could have between 8 and 32 kilobytes – remained safe.The Model 100 is often considered a proto-laptop and sold about six million units. Later upgrades adopted the clamshell form factor so common today, but there were also upgrades to the flat-format machines. And one of those was the Tandy 102 that Ed still possesses today.The 102 debuted in 1986, was thinner and lighter than its predecessors and offered 24 kilobytes as its minimum memory specification.“It's just a beeper, but it works well enough for me,” he wrote. He's also used the machine “as a catalog of CDs stored in CD changer cartridges via a custom BASIC application but that became obsolete when I swapped my JVC 6+1 changer for a 200-disc Kenwood unit with a CDDB interface.”

Another vintage machine that caught our eye this week was a Commodore 64, gutted for use as a keyboard.The user is an outfit called SteelOwl which offers a “room adventure” in Philadelphia, USA. The aim of this meatspace game is to escape from a room by solving several puzzles that dwell within, one of which requires players “to enter in clues they find on VHS tapes in a pretend 1980s video store.”The application isn't running on the C64, but the old machine's chassis is intact so it feel like players are bashing away at the machine's much-better-than-a-ZX-Spectrum keyboard.Steelowl's obtained a USB adapter for the C64 from Britain's Tynemouth Software which charges 40 quid for the kit, in case others out there fancy pressing a C64 into service. Tynemouth Software claim their kit can even connect a Commodore 16 keyboard. The Commodore what? The 16 was the heir to the Vic 20, but flopped just about everywhere. Wikipedia claims the machine went on to be Big in Hungary, a market Commodore chose as a dumping ground for the computer,

But we digress. If you've something older, or odder, than Ed's Tandy 102 let me know and you may appear in a future edition of Runtime. Or use that link to suggest a better name for this column. We considered “Uptime Funk”, FWIW. Israeli security researchers have been able to extract encryption keys from a nearby computer by analysing stray electromagnetic radiation.The attack by computer scientists from Tel Aviv University shows that TEMPEST-style side channel attacks are no longer just the preserve of Mission Impossible and three-letter spy agencies.In a paper, titled ECDH Key-Extraction via Low-Bandwidth Electromagnetic Attacks on PCs, the researchers demonstrate how secret decryption keys in applications using the libgcrypt11 library might be harvested.We show that the secret decryption keys can be extracted from PCs running the the ECDH encryption algorithm, using the electromagnetic emanations generated during the decryption process. By measuring the target's electromagnetic emanations, the attack extracts the secret decryption key within seconds, from a target located in an adjacent room across a wall. ECDH (Elliptic Curve Diffie Hellman) is a standard public-key encryption algorithm used in OpenPGP, as specified in RFC 6637 and NIST SP800-56A. We attacked the ECDH implementation of GnuPG's libgcrypt 1.6.3 (the latest version at the time the paper was written). The attack asks for decryption of a single carefully-chosen ciphertext, iterated a few dozen times, and then uses time-frequency signal analysis techniques in order to extract from the electromagnetic leakage emitted by the target laptop during execution of ECDH decryptions.

The attack rig includes an antenna on a stand, amplifiers, software-defined radio (white box) and an analysis computer. Naturally enough, a lot of digital signal processing and number crunching is involved.The researchers (Daniel Genkin, Lev Pachmanov, Itamar Pipman and Eran Tromer) are due to present their findings in full at the upcoming RSA Conference in San Francisco on 3 March. Security conscious computer users are advised to update their libgcrypt11 packages, something that is already happening. For example, an update for Linux distro Debian can be found here.Many encryption packages on Windows or Macs do not support ECDH, rendering the attack irrelevant. Updates for packages that do support ECDH are already available.Other cryptographic schemes, running on PC-class computers, are also potentially vulnerable to side-channel attacks, the researchers warn. The Israeli team has already demonstrated hacks against RSA and ElGamal, other encryption schemes. More on the Israeli team's previous work can be found in our previous story here.

Unknown and unseen to most users, your smartphone is “talking” in its sleep, and that can sap your battery.The problem? Routing advertisements, one of the fundamental operating principles of the Internet, can demand enough communications to have a noticeable impact on battery life.Router advertisements are multicasts that remind the devices they serve what IP address the router's interface is using (in the old IPv4 world, 192.168.0.1, for example). However, when the smartphone receives that advertisement, it has to process it, even if the screen stays dark.Over at the IETF, a Cisco* engineer called Andrew Yourtchenko and Google* researcher Lorenzo Colitti are suggesting ways that sysadmins can lighten the load on users, at least in the IPv6 world.In particular, the authors say the habits of sysadmins in wired networks, where router advertisements might fly around every few seconds, don't translate well to the world of mobile devices.In RFC 7772, the pair lay down the current best practice for configuring systems so that on devices like phones and tablets, router advertisements don't suck more than 2 per cent of a device's power during sleep mode.
