Evidently tired of smooth running graphics, lightning fast processing and bags and bags of available memory, programmer Dmitry Grinberg decided to go back to computing basics. And then some. As Linux was developed on a 32-bit machine with 1MB of RAM, this has always been considered the minimum system requirements to run the open source OS. Dmitry, however, put this theory to test, building a barebones set-up with just an 8-bit RISC microcontroller at its heart. Running at a somewhat sedentary 6.5KHz, with only 16KB of SRAM and 128KB of flash storage, these are specs that make most phones look like supercomputers. To get things working, Dmitry had to write an ARM emulator so that the system appeared as having a 32-bit processor with an MMU, and it looks like a 30-pin 16MB SIMM was added, plus as SD card to house the Ubuntu image. Despite all this, he was able to load Ubuntu successfully. Sure, it took four hours, and that's after two hours waiting for the bash command prompt, but hey. Grinberg claims that the system is still useable, with the command line typically responding "within a minute." So Dmitri, if you're reading this on the machine, happy new year! Check the time-lapse video after the break to see it in full, patience testing, action.Continue reading World's slowest Linux computer, says 'Hello Wor...' (video)

So, it looks like Precise Pangolin has just crawled out of its Alpha hiding hole, and into the open plains of Beta testing. The Beta 1 version of Ubuntu 12.04 is available to download today, and Beta 2 is already in the crosshairs, one month from now. Being an LTS (Long Term Support) release, we knew changes weren't going to be drastic, but there are some noteworthy ones. We heard RhythmBox would be back as the default media player, and it is, and it looks like Ubuntu One synching also showed up as expected. Under the hood, the kernel goes from 3.2.0-12.21 to 3.2.0-17.27 and RC6 for Sandy Bridge systems has been enabled. The final freeze is only eight weeks away, so if you want to steer the Pangolin in the right direction, curl up on that source link for the goods.
By now, we hope you're mighty familiar with FXI's Cotton Candy -- the much anticipated pocketable computer that just became available for pre-order. We've previously shown photos of the device running both Ice Cream Sandwich and Ubuntu, but now we're able to bring you a video demonstration that may help you better understand what this tiny beast is all about. At the core of the Cotton Candy system is the Exynos 4210 SoC, which capably pushes 1080p video without batting an eye. As such, FXI hopes the miniature computer will gain traction with consumers who want an unobtrusive (and silent) media center or gaming setup in their home. To this end, the company will include the Polkast app for easy access to content and will also bundle games with the system -- though it's not yet able to share specific titles. Those with a sweet tooth may taste the delights of Cotton Candy in March, which will sell for $199.
Canonical's announcement of Ubuntu for Android kicked up quite a stir, but it also left us with a few unknowns. The idea is that your phone becomes a mobile PC, switching from Android into full desktop Ubuntu mode when you dock it to a bigger display, keyboard and mouse. But just how well does it perform? When is it coming? How is it coming? And will tinkerers be able to install it for themselves? Canonical let us into its London office today to try out the software and pepper one of its engineers with questions. First, the good news: Ubuntu for Android is everything it's been claimed to be. It's a functional desktop OS that sits alongside Android, shares the same kernel and has full read / write access to everything on your phone (the connectivity hardware itself plus contacts, emails, videos, apps and pretty much everything else.). It's also ready for ARM-compatible Ubuntu apps, potentially expanding the range of things your phone can do.
Ah, it was indeed only a matter of time. Much like the way HTC caved into fan pressure, ASUS has finally released a bootloader unlock tool for its Transformer Prime TF201. Understandably, the tablet will no longer be covered under warranty once you set it free, but the other catch is that it needs to be running Ice Cream Sandwich in the first place as well. Not that it concerned modder littlesteve who promptly ported a partially-working Ubuntu over to his unlocked slate, pictured above. Steve says there's much work to be done yet, especially with enabling touchscreen support, so keep an eye on his tweets if you're itching to get a taste of his Linux pie. Now, about that mysterious TF300T...
What the Atrix 4G first promised, it looks like the folks at Canonical may deliver. Think back to CES 2011, when Motorola showed us a future where our phone was the only computing device we would need -- only to leave us wanting when its webtop app didn't deliver the requisite functionality for such a future. Well, it turns out Ubuntu now runs on multi-core Android devices and your handset can grant a full desktop experience when docked with a display and a keyboard. It's a customized version of Ubuntu that plays nice with Android, the two OS's sharing data and services while running simultaneously. So, you can still access telephony and texts from the Ubuntu environment while enjoying all the computing capabilities it has to offer, including: Ubuntu TV, virtualization tools for running Windows applications, desktop web browsers, and Ubuntu apps built for ARM. It isn't clear exactly what hardware you'll need to run Ubuntu on a handset, but Canonical has said it works on multi-core devices with HDMI and USB connections. We'll get more info next week when it's shown off at MWC, but until then you'll have to settle for the source below and PR after the break.
Standard Ubuntu, with its Gnome roots and Unity interface may get most of the attention, but there are many different varieties of the world's most popular Linux distro. Most, like Xubuntu and Edubuntu, are community efforts entirely maintained by volunteers. Now Kubuntu, the KDE-sporting edition will be joining the ranks of the unofficial. After seven years, Canonical has decided to focus all of its efforts on Ubuntu proper, and will be ending paid support for Kubuntu with version 12.04. That doesn't mean that the variant is dead, only that it might not be a great choice for enterprise customers. Check out the source for the full letter from (former) lead developer Jonathan Riddell announcing the change.
We knew that the Boxee desktop app's days were numbered, we just didn't realize how numbered. It was only the day after Christmas that we learned version 1.5 would be the last to ship for Linux, Windows and OS X. Now, with January coming to a close, its life is officially being snuffed out. Tonight, as you flip the calendar to February, Boxee will be busy purging its servers of the installable media center software. What that means, in case you hadn't figured it out, is that this is your last chance to download the official app for your desktop OS of choice as the company shifts focus to the Boxee Box and other streaming appliances. Of course, we're sure someone will pick up the torch and update the program, but as far as Boxee is concerned it has no desktop son.
Canonical -- shepherd of the popular Linux distribution Ubuntu -- generally doesn't rock the boat with its LTS releases, but things are going to be different this time around. With 12.04LTS the company is taking its assault on contextual menus to the next level by launching HUD. Mark Shuttleworth's obsession with simplifying user interactions began with the controversial Unity UI in Ubuntu 10.10, and will continue with the Head-Up Display. "Menus require you to read a lot when you probably already know what you want," the distro's founder wrote, "HUD solves many of these issues." Those that have used the search feature in Apple's "Help" menus, or launcher apps like Quicksilver and Alfred, will immediately recognize the goal -- to keep a user's fingers on the keyboard, remove clutter and facilitate quick access to available actions. Listening to music and in the mood for The King? Invoke HUD, type the artist's name and you're presented with your Elvis catalog. It also uses "fuzzy matching" and will remember the actions you most commonly perform to further refine your experience. If you're having a hard time envisioning how HUD works, fear not; there is a three minute video demo awaiting your inspection after the break. Death to menus!
It's still just a proof of concept, which is a bit of a disappointment, but Ubuntu TV was here at CES making its public debut. For the moment it's running on an external PC and being controlled by a Boxee remote, but Canonical hopes one day to have its media-focused Linux distro embedded in TVs. Even in its relatively young incarnation, the 10-foot tweak of Unity seams relatively smooth. A rep showed off the media browser and guide, including the interface for tying in movie rentals and purchases (we guess we know where the Ubuntu One store will be going next). It's all pretty slick and, to be honest, if we could hack this in to the dumb set currently gracing our TV bench we certainly would. Check out the gallery below and the video walkthrough after the break.
