DevJuice: Record UIViews with Glimpse
Glimpse offers an open source library from iOS Developer Wess Cope. It enables you to create QuickTime videos from your UIViews. The library records animations and actions, collecting screen shots over time, building a movie from the results. The API consists of two calls: one to start recording, one to stop. An optional completion block processes a file URL after wrapping up the recording. The project is surprisingly simple. It consists basically of an AV Foundation asset writer (for creating the QT movies) and a wrapper. There's no reason you couldn't use Glimpse for store deployment, for recording gameplay or similar tasks as well. Glimpse is perfect for internal testing -- especially if you want to see how test subjects interact with different view layouts. (Cope's related Variant project helps execute those tests.) Got an open source project you think deserves some DevJuice love? Drop a note into our feedback form.

CoAction Hero board comes with its own OS, simplifies desktop coding (video)
Although we've seen a deluge of tinker-friendly boards, many of them share a dirty secret: they're borrowing someone else's OS. The creator of the new CoAction Hero board, Tyler Gilbert, doesn't think that's good enough for those who want both control and ease of use. His stackable ARM Cortex-M3 design runs its own real-time platform, CoActionOS, that supports Raspberry Pi-style features like file systems and multitasking while abstracting the hardware enough to remove some of the usual headaches. Coding for the CoAction Hero is much like writing a desktop app, and a Qt-based developer kit helps owners write their own interface without knowing the circuitry inside-out. The board is being crowdfunded and won't ship until July if all goes according to plan, but a relatively low $10,000 target and $29 minimum pledge for a device should get the Hero into the hands of intrepid project builders.

Hands-on with Jolla's Sailfish OS (video)
We recently had the chance to spend time with David Greaves and Vesa-Matti Hartikainen of Jolla and take Sailfish OS for a spin. As you might recall, this open source mobile OS builds upon Mer (a fork of MeeGo that includes Qt) and uses the Nemo framework with a custom UI. Like any decent Linux-based OS, it supports both ARM and x86 devices. The company is also behind the Sailfish SDK which is in the process of being finalized but is still open to developer feedback (the source code is available). After seeing Jolla's various demo videos and noting some UI similarities with MeeGo (swipes) and, strangely, with BB10 (peek gestures), we were eager to experience Sailfish OS for ourselves. If you're wondering why the mobile OS is usually shown running on Nokia's N950 developer handset, that's because Jolla employs many ex-MeeGo engineers, so the OMAP-based phone was a natural fit. We were first given a walkthrough of Sailfish OS, then allowed to play with it. Many apps are still being worked on and some are still off-limits (we got in trouble for launching the camera), but what we saw was pretty solid. Take a look at the gallery below, then hit the break for our hands-on video and first impressions.

HP takes Open webOS 1.0 live, shows it supersized on a TouchSmart (video)
WebOS loyalists have been waiting a long, long time for HP's September launch of Open webOS, but the company has made good on its promise with not a moment to spare. Open webOS 1.0 is now available with core browser and e-mail apps, the Enyo 2.0 framework and enough hooks to allow porting to a platform of choice. To prove this last point, HP has gone so far as to port the software to a TouchSmart all-in-one -- a device just a tad larger than a Veer 4G. Lest anyone be hasty and get visions of developing a custom build for the TouchPad, though, they'd do well to remember both HP's disclaimer ruling out legacy support as well as word of the holes that exist in the current Open webOS release. The company needs time to offer open-sourced media support, a Bluetooth stack, advanced network management, faster rendering and newer versions of both Qt and WebKit. The curious can nonetheless try the OS in an emulator today, and intrepid developers can start building their own projects with the code and tools found at the source link.

Digia buys Nokia's remaining Qt assets for 'fraction' of purchase price, eyes Windows, iOS, Android
Nokia's Qt project could be reinvigorated now that it's been bought out in its entirety by Finnish firm Digia, following a partial acquisition last year. Digia is eyeing porting the development platform, used to code applications for Symbian and Meego, to Windows 8 (the PR doesn't mention Windows Phone 8), Android and iOS in the near future. While a fee hasn't been mentioned, it's reportedly a "fraction" of the $150 million that Nokia originally paid when purchasing Trolltech in 2008 -- which probably won't improve matters on the handset maker's balance sheet.

Jolla promises MeeGo will live on, plans new smartphone to reward the faithful
More than a few N9 aficionados felt their hearts sink when important MeeGo team members left Nokia this week, putting the fate of the entire swipe-friendly platform in doubt. Recently-founded Jolla was clearly watching, as it confirmed just in the nick of time that it's planning to carry the torch further. The Finnish startup, which includes important members of the N9 team as well as veterans of the unofficial MeeGo community, not only plans to iterate on MeeGo but to build its very own smartphone with that foundation. Those attached to Nokia's interpretation of MeeGo will have to adapt to a few changes: Jolla's work is based on the related, partly HTML5-driven Mer Project and will have a "brand new UI" to go with the new hardware. It won't be a literal N10 as a result, but we'll find out just what direction Jolla is taking soon -- it's been working on the phone since late 2011 with plans to show its work later this year. As long as some of the N9's spirit carries forward, we have a hunch that a lot of fans won't mind the absence of a Nokia badge.

Spark tablet available for pre-order, still aiming for 200 euro price tag
We're sure some Linux fans broke into a cold sweat over the open source Spark tab. Fortunately it's taken the next step towards their eager paws: the seven inch slab is now up for pre-order. Sign up for one and you'll net a priority order code to ensure you get one of the first units off the production line, alongside 500 points to use at the manufacturer's add-on store. The site still expects to launch the Spark for around €200 ($262), which is a fair chunk of change less than those top-drawer tablets -- and what price can you put on freedom?[Thanks Jose]
Mat Smith02.18.2012Spark pre-orders delayed, but here's a video instead (video)
We had hoped that the Linux-based open-source Spark tablet would be up for pre-order already, but the logistics gods have decreed it not to be. Order registrations are now simply said to go online "ASAP". In the meantime, the developers hope to whet your appetite with this video of the 7-inch budget-slab in action. So it looks a little bit laggy right now, but the team behind it says there's plenty of performance to be squeezed out of it yet. Likewise the UI you see above is optimized for a larger screen, meaning thumbnails and margins should be sharper once those kinks have been ironed out. Hit the source below to get the full update on the pre-order setbacks.
James Trew02.12.2012Spark Linux tablet specs updated, going up for pre-order next week
We already got a brief introduction to the Spark Linux-based tablet, but details were a little sparse. Since then, a few more key bits of info have been added to its Q&A page, which might help sway your purchasing decision. That KDE Plasma Active UI we knew it'd be sporting will stare out at you via a modest 800 x 480 screen, and there's a 1.3 megapixel snapper tucked in alongside for video calling. The 1GHz / 512 MB internals we initially reported remain unchanged and the two USB ports and 3.5mm audio jack we saw in the pre-release picture above also get the official seal. There's talk of GPS making it into the next iteration, but for now you'll have to find your own way. The main news, however, is that pre-orders are pegged for next week, and shipping set for May. The initial focus is on Europe, but plans for it to arrive in US retailers are apparently underway. If that's suitably tickled your fancy, head on over the break and tap the source for more info.
James Trew02.05.2012Meet Spark, the 200 euro slate packing Linux-based Plasma Active UX
As we all know, the Kindle Fire's hot, Apple's selling bushels of iPads, and there's plenty of Honeycomb slates out there for you to choose from, but what if you want a tablet free from corporate influence? Enter Spark, a seven-inch slate that comes running the Plasma Active UX, an open-source OS based on Linux kernel, KDE's multi-platform Plasma environment and a dash of Qt for good measure. Now, this isn't just a consumer tablet -- Spark's aimed at "those who love writing great software... using the typical Linux tools" -- but it will offer access to ebooks from Project Gutenberg, plus Qt and QML apps, too. It's powered by a 1GHz AMLogic ARM processor, has a Mali-400 GPU and comes with 512MB of RAM, 4GB of internal storage, plus an SD card slot for future expansion. Modest underpinnings, to be sure, but for €200 ($262), you can't expect quad core silicon, right? Naturally, order and delivery dates remain a mystery, but plenty of other info about the open-source slate can be found at the source below.

Qt developers gain NFC support with Nokia's latest SDK update
Nokia's development community just got its first taste of near field lovin' with the first Qt SDK to support NFC. While you'll be forgiven if you're not up in arms over the latest revelation, owners of the company's latest handsets can soon expect a greater number of useful apps that take advantage of this newfangled technology. The developer tools enable the creation of applications for both Symbian and MeeGo, and allows software authors to simulate NFC tags and create events based around them -- all within the virtual environment. Programmers looking to dip their toes into the water will find a couple of experimental apps from Espoo's pride that highlight near field communication, along with the complete source code for each. Sounds like it's time for some to make a pot of coffee and let the coding madness ensue.

Brain scanner app lets you show off your smarts on-the-go
Forget learning how to open a champagne bottle with a saber, because this smartphone brain scanner probably has it beat for coolest party trick ever. After you pull out that 14-channel EEG headset you have lying around, all you need to do is attach the probes to your date's dome piece to measure his or her neural activity on your Nokia N900. The app then goes to work, taking binary data and reconstructing it on screen in 3D. The result? A new way to elimi-date Match.com candidates based on the real-time image of his or her melon. We can't promise it'll get you a second date, but we can give you a glimpse of the app in action after the break. [Thanks, arek]

Nokia N9 first hands-on! (update: video)
The N9 has arrived. Functional units of Nokia's long-awaited MeeGo smartphone have finally landed into our eager hands and we've got a gallery of images to provide you with below. What we can say from our first experience is that we're in the presence of a fantastically designed device with a gorgeous AMOLED screen and some highly responsive performance. Hold tight as we're updating our fuller impressions after the break, where you'll soon be treated to our first hands-on video with the Nokia N9. Update: Hands-on video plus a live demonstration of the N9's ability to pair Bluetooth devices over NFC (very impressive!) can now be found after the break. %Gallery-126795%%Gallery-126785%

Nokia promises strong Symbian devices through Windows Phone transition, major OTA update this summer
Nokia loves telling the world about the 150 million Symbian handsets it will ship in the years to come. Problem is, that's far from a factual statement -- it's a goal, a hope, and something that will only be possible if developers and fans don't abandon the platform wholesale as the company transitions from Symbian to Windows Phone smartphones over the next two years. As such, Nokia is desperately trying to convince us that Symbian and the Qt developer framework are far from dead. In an open letter of encouragement to developers from Purnima Kochikar, VP of Nokia Forum & Developer Community, Purnima attempts to coax devs into fine-tuning their Qt skills in preparation for a "strong portfolio" of new Symbian products with "GHz+" processing and faster graphics coming in 2011 and 2012. Presumably she's talking about the T7, X7, and E6 leaks among others. And because Symbian is still the leading smartphone platform in markets like China, India, Russia, and Turkey, she hints that Nokia will likely continue to support Symbian well beyond the transition to Windows Phone, at least in select markets. Of course, hardware has never really been Nokia's issue so it's nice to hear Purnima commit to a first major Symbian user experience update this summer that includes the new home screen, icons, browser, and navbar we've already seen, in addition to a "fresh look and feel" to the Ovi Store and Maps with the latter also getting a integrated social media services update. The Symbian update -- some of which has already been seen on the C7 Astound -- will come to "all users" over the air. Too late to save the platform but just in time for the Symbian faithful.

Canonical christens Ubuntu 11.10 'Oneiric Ocelot' (update)
Canonical's still one month away from letting Natty Narwhal (also known as Ubuntu 11.04) out of the cage, but it's already teasing us with another OS flaunting an alliterative mammalian monicker. Like the Narwhal before it, Oneiric Ocelot (or Ubuntu 11.10), due out this October, will offer a 2D OpenGL-based Unity interface to support older computers, as well as Qt -- you know, the framework Nokia loved and left hanging. You can also expect Ubuntu to scale back on the number of cloud services with the Ocelot, as it gears up for the release of the as-of-yet unnamed Ubuntu 12.04 LTS (long term support). For now, that's all she wrote, but if you're dying to find out how they come up with those adorable Animalia appellatives, check out the source link below. Update: Oneiric Ocelot has also apparently devoured Ubuntu Netbook Edition whole -- starting with Ubuntu 11.04, the products will be completely unified and (according to Canonical) work equally well no matter the form factor.

Nokia sells Qt commercial licensing and services business to Digia
Now that Nokia has shifted to a Windows Phone-centric smartphone strategy, it's only natural for the company to divest itself of responsibility with regard to the Qt framework at the heart of Symbian and MeeGo development -- a platform Nokia acquired from Trolltech back in January of 2008. We just got word that Digia will acquire the Qt commercial licensing and services business from Nokia, including the transfer of some 3,500 desktop and embedded customers actively using Qt today. Sebastian Nyström, Nokia Vice President, Application and Service Frameworks, had this to say about the agreement: "Nokia will continue to invest in developing Qt as a cross-platform framework for mobile, desktop and embedded segments, focusing on open source development and expansion, we wanted a partner who can drive the commercial licensing and services business around Qt. Digia has proven, in-depth Qt expertise, operational excellence and a keen interest in growing and improving the overall Qt community and so well positioned to expand the Qt Commercial licensing and services business." So, if you're interested in developing in Qt commercially, Digia will be your contact just as soon as the transaction completes sometime later this month. [Thanks, Nisse]

Nokia giving developers free E7 and Nokia WP7 handsets
Nokia's fighting an uphill battle to retain its community of developers as it switches focus to Windows Phone and Microsoft's Windows Phone Developer Tools from what was a joint Symbian / MeeGo smartphone strategy unified under the Qt development framework. As such, Espoo just notified its Launchpad members that they'll be receiving about $1,000 in free hardware in the form of Nokia's new flagship E7 QWERTY slider and a "Nokia WP7 device" just as soon as it's available. Nokia's also tossing in a few other incentives like free access to the next Nokia World / Nokia Developer Summit, three months free tech support for all Nokia technologies (limited to 10 tickets), a free User Experience evaluation for one app, business development assistance, and help publishing apps on the Ovi store. This is also great news for us as the chance of seeing leaked pics of that first Nokia WP7 device have just increased dramatically.
Thomas Ricker02.18.2011Nokia to developers: no Qt for Windows Phone development
Nokia's been beating the Qt warpath for years after purchasing the developer framework from Trolltech back in January of 2008. In fact, Nokia just made the switch to Qt exclusively back in October in a sign of its unrelenting support for the unified development environment. That, like all previous Nokia strategies, is in for a big change today. While Qt will continue on as the development framework for Symbian and MeeGo, Microsoft will provide its free Windows Phone Developer Tools (Visual Studio 2010, Expression, Silverlight and the XNA Framework) to developers interested in developing for Nokia Windows Phones (get used to that phrase) while providing "guidance" to anyone wishing to port their apps to WP7. In other words, Qt will not be adapted for Windows Phone 7 APIs. Full letter after the break to what we imagine is a very disgruntled and previously loyal Nokia developer community.
Thomas Ricker02.11.2011Nokia ends talk of Symbian^4, adopts HTML5 in Qt framework
Things are turning upside down in Espoo today. Besides, earnings and reported job cuts of some 1,800 employees, Nokia also announced that it'll be streamlining its development strategy to unify environments for Symbian and MeeGo. Nokia's new approach calls for the adoption of Qt, and only Qt, as its application development framework from today onward. Here's what that means for new N8 owners: You can buy a Nokia smartphone confident that any improvements introduced later to the Symbian platform, such as the user interface, can be made available to download on your device as well. No need to wait for Symbian^4 - the improvements we were planning for Symbian^4 will be introduced as and when they become available. In fact, we will no longer be talking about Symbian^3 or Symbian^4 at all – it will be one constantly evolving and constantly improving platform. Sounds like a smart move to us. After all, it's Symbian's UI, and not the OS, that we have the most trouble with -- an issue that Nokia readily concedes. So the faster they can improve it -- even pieces of it in a continuous evolution of the experience -- the better. Nokia also announced support for HTML5 web content and applications for the Symbian and MeeGo platforms in both Qt and the browser. Click through for the press release and to hear Rich Green, Nokia CTO, discuss the new strategy.

Nokia N8 review
The first time Nokia's N8-00 popped up on our radar was way back in early February of this year. On that chilly, misty morning, we learned of a mythical being capable of shooting 12 megapixel stills, recording 720p video, outputting via HDMI, and -- most importantly -- ushering in the promised Symbian^3 touch revolution. It's been a long road of leaks, teasers, hands-ons, and previews since then, but at long last, the legend of the N8 has become a purchasable commodity. All the early specs have survived, including the 3.5-inch AMOLED display, but the key question today, as it was at the beginning, relates to that all-new software within: does Symbian^3 succeed in elevating Nokia's touchscreen experience or does it drag down an otherwise stellar combination of high-end parts? For that verdict and much, much more, join us after the break.%Gallery-103738%%Gallery-104212%
