    Watch the above video closely, because you might just miss the moment: according to the latest post on MSDN's Building Windows 8 blog, Microsoft's next-gen desktop OS will see a hugely improved boot time thanks to a clever technique. Rather than closing both the user session and the kernel session like in a traditional shutdown, Windows 8 will preserve the kernel session on the disk, thus creating a "hiberfile" that's much smaller than that of the usual Windows hibernation -- see the diagram after the break for a clearer idea. The result? An amazingly fast system bootup -- even with the battery removed to begin with -- that claims to be 30 to 70 percent faster than most systems tested by Microsoft. We're itching to test this feature on an SSD ourselves, but until then, you can head over to MSDN's blog for the full technical explanation.

    Your smartphone and / or tablet is just begging to get updated. From time to time, these mobile devices are blessed with maintenance refreshes, bug fixes, custom ROMs and anything in between, and so many of them are floating around that it's easy for a sizable chunk to get lost in the mix. To make sure they don't escape without notice, we've gathered every possible update, hack, and other miscellaneous tomfoolery from the last week and crammed them into one convenient roundup. If you find something available for your device, please give us a shout at tips at engadget dawt com and let us know. Enjoy! Official Android updates The biggest update we saw this week was a widespread push of Android 2.3.3 to the Motorola Droid 2. This one is done OTA, so simply go into your settings menu and check for updates to see if it's there. (thanks to everyone who sent this in) While we saw a rollout of Android 2.3 to a select few LG Optimus Ones in June, we're hearing reports that the update's now getting pushed out again to a few more regions. This refresh must be done manually through LG's updater tool, so you'll definitely want to check to see if your phone is one of the lucky recipients. [via PocketNow] US Cellular took to its Facebook Page to let customers know it's working on revamping the Samsung Mesmerize to Gingerbread at some point, though no official date or timeframe was given aside from "as soon as possible." [via AndroidCentral] HTC announced the arrival of Android 2.3 for the Thunderbolt and Droid Incredible this month, via its Facebook page. [via AndroidCommunity] In fact, some users have already reported getting Gingerbread for the Incredible, and we suspect the rollout will be complete no later than the end of the month, to fulfill the company's promise. [via Phandroid] Gingerbread is in the plans for the Motorola Milestone 2, and according to the company the refresh will begin rolling out in early Q4. [via MyDailyGadget] The Samsung LC11 LTE mobile hotspot is getting a new build, EF07, that appears to improve its handling of multiple devices and congested WiFi locations. It also adds security patches and new protocols. [via Verizon] An update for the Droid 3 was apparently available to soak testers and leaked online, but was pulled from Motorola servers shortly thereafter. It appears to add video chat support in GTalk and adds a new radio that's supposed to save battery life. The via link still has the update available for anyone interested. [via Droid-Life] Unofficial Android updates / custom ROMs / misc hackery The root method used on most Motorola Android devices has been employed to root the Droid Bionic before it's even been released. [via Droid-Life] LG has released the kernel source for its Gingerbread build of the Optimus S. [via AndroidCentral] The HTC Dev site expanded its support for the bootloader unlock tool this week, now encompassing all versions of the Sensation -- including T-Mobile's. [via AndroidCentral] Other platforms SPB Shell 3.0 is now available for Symbian^3 devices. It brings a fresh 3D-style UI to the OS, and can be yours for $15. [via IntoMobile] Updates already covered this week HP planning TouchPad OTA update for added functionality HTC Flyer Honeycomb ROM leaks Samsung Nexus S updated to 2.3.6, fixes voice search and breaks tethering

  • HTC Developer site goes live: OpenSense SDK and kernel source offered aplenty

    HTC's flipped the switch on its development website, which was designed to be a "one-stop shop" for a wide variety of SDKs and other resources for developers. As promised, the manufacturer's OpenSense SDK -- which includes a S3D SDK for HTC's 3D stereoscopic interface and pen SDK for its Scribe feature -- is now available for download; there's also plenty of kernel source codes to peruse and access. Finally, the Bootloader Unlock web tool, one of the most highly anticipated pieces of software that the company's promised to unleash, only shows as "coming soon" on the site. There hasn't been any official word on when it'll go live, but we're expecting it to happen later this month as the EVO 3D and the Sensation both get adorned with their unlocks. It's great to see the company follow through completely on one of its promises, eh? [Thanks to everyone who sent this in]

    Aftermarket ROMs for the Incredible S and Desire Z (and their US variants) aren't exactly breaking news -- the rooting community's been cracking away at those handsets since their launch. Release their Gingerbread maintenance source code, however, in addition to the Flyer's kernel code and you'll have developers foaming at the mouth. Which is exactly what HTC did over the weekend, paving the way for a new flood of ROM-flashing options to hit your hacked handsets. Android modders should hit the source below to download the AOSP goods.

  • Xbox 360 pops up in Win 8 code, console game compatibility coming to the PC?

    It's no secret that Microsoft is planning on integrating Xbox LIVE into Windows 8, but rumors are now swirling that Xbox 360 games might actually be playable on the next version of Redmond's OS. References to "XBOX_360_SYSTEM_CRASH" have been found in the kernel code -- an odd bit of text to show up in software that's not designed to run on the 360's PowerPC CPU. There are, of course, other, more mundane possibilities -- like the ability to remotely control your console to trigger update and game downloads, or to receive notifications from the machine on your desktop. But, if Microsoft is bringing Xbox titles to the PC, it would only serve to solidify Windows as the platform of choice gamers. Guess we'll just have to wait bated breath to see what Ballmer has to tell us in January.

  • Linus Torvalds releases Linux kernel version 3 to celebrate 20 years of penguin-powered computing

    It's been nearly twenty years since Linus Torvalds let loose Linux on an unsuspecting world, and yesterday he finally updated the open source OS kernel to version 3.0. This third iteration, currently named 3.0.0-rc1, comes 15 years after 2.0 first hit the web and brings driver support for Microsoft Kinect -- a move that should have visions of sugar plum fairies (or maybe just Android avatars) dancing in hackers' heads. Also included is code optimized for AMD's Fusion and Intel's Ivy and Sandy Bridge silicon, and some updated graphics drivers, too. Despite these tasty new treats, Torvalds is quick to point out that this new release is an evolutionary change and unleashing the big three-oh was all about moving into a third decade of distribution, not about overhauling the OS. There's still work to be done, as it is a release candidate in need of refinement, but curious coders can grab the latest Linux at the Kernel.org source link below.

  • Eee Pad Transformer gets overclocked to 1.4GHz, deemed less than stable

    While many of you continue your quest for an Eee Pad Transformer, some folks, predictably, have already figured out how to overclock it. Netarchy over at the XDA forum posted a custom kernel allowing hackers to crank the tablet's clock speed to 1.4GHz, the same peak reached by the ViewSonic G Tablet. Beware, though, that performance at that speed has proven unreliable, so for now the dev recommends a more modest 1.2GHz to avoid data loss, a meltdown, and "injury of assorted puppies." Par for the course, really.

  • Sony Ericsson teaches course on building custom Linux kernels, admission is free

    When Sony Ericsson stepped out of line and opened its bootloader unlocking service, it provided a tacit acknowledgment that users should have the ability to use and abuse their phones however they see fit -- even if it voids the warranty. Frankly, we applaud SE's move, despite the caveat that supported handsets cannot be SIM-locked to a carrier (or CDMA, for that matter). Now, Sony's embracing its own movement and is teaching a free online class (of sorts) on how to build a Linux kernel and flash it to your phone. Of course, the article requires that you get comfy with the command line, but whether you're an Android developer, a casual enthusiast, or a curious observer, this tutorial is worth reading and learning from. Welcome to Computer Lib for the handset generation -- where you can and must understand smartphones now.

  • Motorola Xoom sees MicroSD card support enabled in latest version of Tiamat kernel

    Aside from shipping without Adobe Flash Player preloaded, the Motorola Xoom also has the ignoble distinction of having a non-functioning MicroSD card slot. We're assured by the company's reps that the update to make storage expansion work is imminent, but if you have to have it right this very minute, there's now a kernel for you. It goes by the name of Tiamat, originating on xda-developers (as most good things do), and has recently stepped up to support MicroSD card storage. You'll find download links and instructions for Tiamat at the source link, plus a few happy reports of it working as advertised. [Thanks to everyone who sent this in]

  • Nexus S overclocked to 1.2GHz, runs too damn fast for its Bluetooth to work

    Even at its default 1GHz speed, Samsung's Hummingbird is one of the finest mobile processor around, but are you really going to complain about getting the option to crank an extra 200 milion clock cycles out of it? Morfic over on the xda-developers forums has delivered a kernel permitting Nexus S owners to achieve just that, although he still has to fix an issue that disables the phone's Bluetooth capabilities.Still, if you value ludicrous speed over wireless peripherals, the source link is your friend.

    Hold on to your hats, people, there's a wind of awesomeness coming through. The Nexus S is no longer the only Gingerbread game in town, courtesy of supercurio over on the xda-developers forum, who has ported the hot new phone's Android 2.3 install over to its Samsung forefather, the Galaxy S. The port is described as being unmodified from the Nexus S original, although quite a few basic functions like voice, WiFi, and GPS (insert joke about Galaxy S GPS woes) aren't yet operational. All the same, we agree with supercurio that it's looking "super smooth" and look forward to seeing him and the rest of the xda crew polish this stock Android baby off in short order.

  • Palm Pre hits 1.2GHz courtesy of SR71 Blackbird kernel, not for the faint-hearted

    Whoa! After breaking the 1GHz barrier just three weeks ago, dauntless modder unixpsycho is back with yet another insane hack for the aging Palm Pre. What's new? Why, this "SR71 Blackbird" custom kernel, which simply pushes the poor little OMAP3430 processor up to 1.2GHz -- that's twice the original clock speed, just so you know. As glamorous as it sounds, potential users are triple-warned about this mod potentially failing the webOS device in one way or another, despite the built-in speed-scaling mechanism to cap the device at 55 degrees Celsius (131 in Fahrenheit). And needless to say, don't expect your stock battery to hold up for more than a few blinks once implemented. Good luck, pilgrims.

  • Nexus One now a step closer to FM radio support, thanks to modified kernel

    As you may or may not be already aware, the Nexus One and HTC Desire have the same Broadcom chip. Seems trivial at cursory glance until you realize the Desire has a FM radio app, which should ergo be just as feasible on the Google-branded device. Cut to xda-developers' intersectRaven, who's released a custom N1 kernel that theoretically brings life to the FM receptor. It's available to download, but as for when you'll get a chance to really use this yourself, that's entirely up to the custom ROM developers updating their respective wares. For his part, Paul O'Brien said today he's already got it working on an upcoming Froyo Sense build for the device -- hang tight, folks, it's coming. [Thanks, John]

    If you own a Pre, you like to tempt fate, and you don't faint at the mere thought of your phone melting into a nondescript heap of plastic and silicon, have we got some exciting news for you: some crazy dude with a death wish has somehow eked an honest gigahertz out of the Pre's OMAP3430 processor that normally plods along at 600MHz. Of course, this isn't the first time the phone's been overclocked, but traditionally, those overclocks have topped out around 800MHz -- so if you need serious speed and don't mind nuking your battery at a record pace, this so-called "F105 Thunderchief" kernel project is one that you're going to want to keep an eye on. The project's owner says "do not install this if you like your phone," so... you know, proceed with extreme caution, especially considering that your warranty's probably going to dry up as fast as your battery. Follow the break for the blood-curdling action on video.

    If you're a Pre or Pre Plus owner who has been watching longingly as we've covered the recent spread of overclocking hacks for the thing, but didn't quite feel up to wading through page after page of forum discussions to figure out just how to apply them, the process just got a easier. Like, a whole lot easier. Super PreKernel enables you to go to 550, 600, 720, and even 800MHz with just a single tap. And, when it's time to put on those fake glasses and play Clark Kent, you can drop back down to 500MHz just as easily. It's all thanks to a number of Palm-loving hackers who have put together a truly moving video demonstration of the whole process that's embedded below. We encourage you to enjoy it now, because the selection of copyrighted musical accompaniment for the clip will probably result in it surviving about as long as a bottle of Superman's chosen hair product. Update: We got a note from caj2008 that an updated version has been released, this one fixing a few issues and offering better compatibility with OS 1.4.0, 1.4.1, and 1.4.2.

    They knew this day was coming, but still, we can't help but feel like there must be some higher-ups at Verizon that are squirming today at the knowledge that the innermost workings of one of their highest-profile smartphones -- the Droid Eris -- are now available to anyone willing to invest the couple minutes that the package takes to download. This should give hackers some more elbow room to cook custom ROMs for Verizon's remix of the Hero -- and if they can beat an official Android 2.1 release for the phone by even a single day, that sounds like a win in our book.

  • HTC posts kernel source for Tattoo, Sprint Hero

    The terms of the GPL require that developers of Android handsets out the source code for their phones' platform kernels, something HTC, Samsung, and others have generally been good about (emphasis on "generally") -- and now HTC's gone ahead and pushed a couple more notables into the public domain. The Tattoo and the Sprint-branded version of the Hero are the latest to get their innermost software workings exposed; the Tattoo should be an interesting choice here because it's one of the lowest-end Android sets released to date, and the Sprint Hero's been taking some heat for a while now for its lack of code exposure. We're happy to see HTC stay in compliance, yes -- but really, we're even happier to know that it's now in the hands of people who intend to tear it apart and do cool stuff with it.

    What's better than a Dashboard widget that can display a Mac OS X kernel panic? A full-on screensaver that can simulate one, of course! Mark Johns of Doomlaser has built an eerily realistic kernel panic screensaver, right down to the slowly dropping grey shade of despair, that will surely induce panic in the hearts of its victims in the way that only the haunting question of "oh crap, did I save?!" can. For a nice touch of style, it can even pause iTunes to really stop the show.Watch a demo of the screensaver here in this post, or head over to YouTube for the original. Finally, you can snag your own pranktastic copy from Doomlaser.

  • Use Mac OS X keyboard and shortcuts on Windows

    If you're jonesing for your Mac OS X keyboard shortcuts to work on Windows, or if you just can't give up Apple's keyboard while using Boot Camp, the AppleK Pro keyboard driver for Windows might just be your fix. This little driver allows you to use most Mac OS X shortcuts (such as cmd - shift 3/4 for screenshots and cmd - opt - esc for the Windows Task Manager), and you can even plug in an Apple USB keyboard to keep on truckin' (great for the Boot Camp users in the audience).My big gripe with AppleK Pro however (besides the logo), is its outlandish $25 price. $5 - sure. $10 - I'd consider it (if I had to use Windows, that is). Even $15 might be reasonable, as long as you throw in the answer to the meaning of life or something. But $25 for some keyboard shortcuts? I might as well buy a new keyboard - at least then I could have one of those cool Matrix-style, multi-keyboard setups and act like I can actually see things when I stare at scrolling Klingon-ish code. Maybe these guys should hook up with MacZOT to cut the Mac shortcut addicts a break.

  • Clarification: Apple has not closed the Intel-based Darwin kernel

    OSNews is reporting that Ernest Prabhakar, Apple's Open Source and Open Standards product manager, has stated in the Fed-Talk mailing that Apple has not actually closed Mac OS X's Darwin kernel for the Intel version of the OS; they simply haven't released it yet. Speculation about Apple closing the kernel arose from the fact that other non-kernel Darwin sources actually have been released, and the previous PowerPC-based kernel is still available as open source as well.Ernest wanted to make sure that tech media didn't confuse 'speculation' with 'fact'. A good lesson we all could benefit from.
