MediaPortal posts 2.0 alpha media hub and new remote apps, teases 1.3 beta with Titan
Home theater PC owners only just recovering from their turkey or tofu comas will have some updating to do -- MediaPortal has been busy. The experimenters among us will most likely want to jump straight into the promised MediaPortal 2.0 Alpha Autumn, which carries new visual layouts and video backgrounds, a news plug-in and a party-friendly music player. New versions of remote tools like aMPdroid, MPExtended, WebMediaPortal and WifiRemote bring their own slew of upgrades, such as HTTP Live Streaming in MPExtended or a "what's new" interface in aMPdroid. We'll readily admit that our eye is most drawn to the yet-to-be-launched MediaPortal 1.3 beta's addition of the Titan skin you see up above: going beyond what we saw in October, the extra-polished look goes a long way towards accommodating newcomers and the style-conscious. We're still waiting on publicly accessible 1.3 beta code, but everything else is waiting for open-source media hubs at the included links.
Mac Game of the Week: Battle for Wesnoth is an open source classic
Battle for Wesnoth is one of my favorite Mac games of all time, and best of all, it's completely and totally free. It's an open source game back when creating open source games was the thing to do, but unlike most other open source games, it has endured and flourished, currently sitting at version 1.11.0. Battle for Wesnoth is a turn-based strategy game, and it's really excellent -- it's based on a filled-out fantasy world, there are plenty of units to fight with and against, there's a full story mode to play, and there's a skirmish mode where you can just pit different factions against each other to your heart's content. And if that doesn't give you enough to do, there's also a ton of great user-made content campaigns, which bring all-new stories and content to the title. And since it's all open source, you can even jump in and create your own art, scenarios, units, or maps for the game. There's an unbelievable amount to do with this engine, and again, it's all for free. Battle for Wesnoth is a classic game (that's also available for iOS, by the way, thanks to a hardworking developer), and as far as I'm concerned, it's a must-install on every Mac I've ever owned. Definitely go grab it and play it -- it's available for download for free from the main website.
'A Slower Speed of Light' is an open-source game on special relativity from MIT Game Lab
The behavior of light may seem static and uninteresting (it's bright and fast, we get it), but there's actually an incredible amount of science going on that we generally don't experience during our normal lives.A Slower Speed of Light, a new open-source game for PC and OSX from MIT Game Lab, explores the more intricate and interesting behaviors of light in a "relativistic game engine." As players collect objects, the speed of light is slowed and players are able to experience phenomena such as the Doppler effect, time dilation and the Lorentz transformation, among others.While the open-source aspects of this project are not yet available, the plan is to release the game's Unity3D-based engine as OpenRelativity sometime in 2013. For now, the game itself can be downloaded here. %Gallery-170585%
How-to: Picking a Window Manager in Linux
When using Linux, or just about any open source operating system out there for that matter, there's a proverbial Santa's knapsack of graphical user interfaces (GUIs) available. When you boil this topic down on the basic level, you've got two choices: Use a fully featured Desktop Environment (DE) with tons of bells and whistles, or alternatively you can use a slimmed-down and streamlined Window Manager (WM). We're going to get you up to speed on what each of these actually are, some reasons why you'd want to choose a WM over a DE, as well as some of the options you have among the Window Managers out there. Catch us after the break to join the age-old battle of choosing your GUI.
Open webOS-powered HDTVs said to be on the way from... LG?
If you were wondering what was next for webOS now that it's gone all open source on us, webOS Nation chimes in with word that Gram is working with LG to bring it to connected HDTVs. Several names from the HP / Gram team are dropped as being involved in the effort, which reportedly was under way even before HP revealed it would spin the project off as an independent. Of course, when we actually saw Open webOS 1.0 it was already stretching to fill the space of an HP TouchSmart computer screen (project architect Steve Winston specifically mentioned hotel kiosks as a possibility, a market LG is all over) so it makes sense that larger displays have been a target. With LG supposedly both looking to replace its existing NetCast smart TV platform and unhappy with Google TV based on its rate of adoption and Google's terms, engineers have been working to port the software to its dual-core L9 chipset. In the past LG has pursued voice and motion control, the aforementioned Google TV integration and even Plex support to make its smart TVs more appealing, and has founded the Smart TV Alliance for cross platform apps. We only have to wait until CES 2013 to see if webOS is next up to power its efforts, stay tuned.
Meridian 59 player teases 3-D client
Now that Meridian 59 is available to anyone to tinker with as an open source project, we've been curious what the playerbase might do with this granddaddy of MMOs. One enterprising soul has started the Meridian 59: Community Client Project to bring the title fully into the realm of 3-D. In a brief video, the possibility for a 3-D Meridian 59 is teased with some basic landscape rendering and strategically placed bushes and trees. While the author admits that it's still crude and in the beginning stages, it's tantalizing to think about this 2.5-D title finally breaking through to the third dimension. Of course, purists don't have to worry that their game is under attack, as the production servers for the classic Meridian 59 experience are still alive and kicking. You can check out the community project video after the jump. [Thanks to Dennis for the tip!]
Romibo therapeutic robot, eyes-on (video)
Between old Paro the robo seal and the original iteration of Keepon, we've seen plenty of adorable robots designed for therapeutic purposes. Romibo's creators have no qualms admitting that their own creation is following in those cuddly footsteps, but what sets their furry 'bot apart from much of the competition is a focus on (relative) affordability. For starters, there's the fact that Romibo is being offered up as an open-source project online, letting do-it-yourselfers build their own versions and contribute custom designs. The company's also hoping families will get into the act, making sure that Romibo is "able to be assembled by a neurotypical child 10+ and a parent" -- and then there are the plans to offer up workshops to let folks build robots to be donated to special needs facilities. Once built, Romibo can drive around, blink its eyes, speak and move its antennae. Crack it open and you'll find WiFi, bluetooth, light sensors, an IR Proximity sensor, accelerometers and a big 'ole Arduino Mega. There's a certain amount of autonomous functionality (watch in the video below as Romibo's handler warns about it driving off the edge of the table), or you can control the robot via an iPad app. You can also use an SD card to help teach it some new words.%Gallery-168983%
MooresCloud Light runs Linux, puts LAMP on your lamp (video)
Yes, we'll admit that we borrowed that pun in the title. MooresCloud founder Mark Pesce's Xzibit reference is still a very apt description of the Light, his company's Linux-based LED lamp. The Australian team's box-shaped illumination runs the open OS (including a LAMP web server stack) on an integrated mini PC with an accelerometer and WiFi. The relative power and networking provide obvious advantages for home automation that we've seen elsewhere, but it's the sheer flexibility of a generalized, web-oriented platform that makes the difference: the Light can change colors based on photos or movement, sync light pulses to music and exploit a myriad of other tricks that should result from a future, web-based app store. When and how the Light launches will depend on a Kickstarter campaign to raise $700,000 AUD ($717,621 US) starting on October 16th, although the $99 AUD ($101 US) cost is just low enough that we could see ourselves open-sourcing a little more of the living room. At least, as long as we don't have to recompile our lamp kernel before some evening reading.
iControlPad 2 gets funded, adds QWERTY keypad and smartphone mount
Product 3 LLC, the company behind the original iControlPad, has successfully funded a successor: folks, meet the iControlPad 2. While there isn't much to its name, the sequel boasts a handy QWERTY keypad along with an optional swivel-mount that you can attach to any smartphone. It works over either microUSB or Bluetooth, and true to its open-source roots, is said to support the Ouya, the Raspberry Pi and pretty much any other device you can throw at it. What's more, it can be programmed to control almost any app via its support for touchscreen mapping. There's still room for additional backers, so you could try to get a raw version for $69 or a boxed edition for $75 if you manage to pre-order in time. Let's just hope the sequel doesn't experience the same delays as its older sibling, especially given the $150,000-plus the company earned in its Kickstarter campaign. [Thanks, Craig]
Samsung creates F2FS file system for NAND flash storage, submits it to the Linux kernel
Has the lack of NAND flash storage-optimized file systems been bugging you? Then you've got something in common with Samsung, which has developed F2FS (or "Flash-Friendly File-System") for the memory of choice for mobile devices and its specific "internal geometry." It's based on a log-structured method, but tackles problems associated with older file systems intended mainly for retro, spinning-disk storage. The company isn't keeping its hard work behind lock-and-patent either -- it's gone open-source and submitted the file system to the Linux kernel, meaning you could see it implemented in Android hardware of the future. It's nice to see Sammy contributing code for the greater good, and if you've got the skills to understand it, a low-down of F2FS is available at the source below.
Adafruit releases WebIDE alpha for Raspberry Pi, eases beginners into coding
If you've been intrigued by the Raspberry Pi but were hesitant to get one because you're new to Linux, Adafruit has a solution for you. The team that brought us the Raspberry Pi Education Linux Distro has come up with a special WebIDE (Web Integrated Development Environment) designed to run on the affordable barebones computer. It's entirely web-based so there's no need to install any software -- just launch a browser, hook up your Pi, and you're ready to go. To make life easier for coders, the platform has a terminal built in, plus there's an automatic updater included to keep folks running only the freshest version of WebIDE. It's currently at the alpha stage, so only experienced users should install it for now, but Adafruit's hoping to roll out a stable release suitable for programmers of all levels sometime soon.
Jolla resuscitates MeeGo with 'Sailfish' OS, plans to show off new device this November
If competition breeds innovation, then there's plenty promise in this latest mobile development from Jolla. The Finnish company, comprised of former Nokia employees, is poised to enter yet another combatant to the wireless arena with a MeeGo-based OS, codenamed "Sailfish," as early as this November. According to The Wall Street Journal, an initial round of funding has raised €200 million to push the effort forward and the small start-up is investing €10 million of its own to bolster the platform's prospects. Having been recently abandoned by Elop and co. after the arrival of the N9, this iteration of the operating system will continue to be open source and should pave the way for OEM adoption, although certain aspects of the UI will be licensed. According to CEO Jussi Hurmola, the new hardware's expected to hit next month -- just in time for a glut of other smartphone bows. Until then, we'll reserve our judgment and hope for the best.
Linux 3.6 kernel released with 'hybrid sleep' capability, Google's TCP Fast Open extension
The last couple of Linux kernel updates have been a bit of a circus, with Android merging in the 3.3 ring and graphics integration on a (noisy) 3.4 center stage. Version 3.6 of the open source kernel has less flashy, more serene features this time, with hybrid standby, a revised file system and other esoteric networking and architectural features befalling the penguin. That sleep mode, which caches the RAM contents to a disk to prevent data loss, has been available for a while now on Windows and Mac machines and will be especially handy on Linux laptops. The so-called Btrfs file system has also been updated (though is still in a developmental mode) and Google's experimental TCP Fast Open extension has been added, along with additional network drivers, more virtualisation options and additional processor support. Sleepwalk to the source for the complete changelog.
Slackware 14.0 now available, freshens and simplifies a Linux vanguard
When it comes to Linux distributions, Slackware could well be called the archetype. It's not just one of the longest-serving releases at nearly 20 years old -- it's designed to be "pure" and cut back on customized apps, many graphical interface assistants and the requirement to download anything during the installation process. Pat Volkerding and team have nonetheless given us a bit of a break with the launch of Slackware 14.0. While many open-source fans will be downloading a copy for the more recent Linux 3.2.29 kernel and other updated packages, ease of use is the guiding principle for the new build: there's now a graphical NetworkManager interface to manage wired and wireless connections, for a start. In tandem with the newer kernel, updated versions of the KDE and Xfce desktop environments also result in much broader hardware support than many veteran users will remember. Slackware is now much more savvy about removable storage, accelerated 3D video, SATA and other features that have sometimes demanded command line trickery. Anyone can download the revamped distribution for free, including for ARM-based devices like the Raspberry Pi, although we'd consider springing for the $33 subscription to CD-based copies of Slackware to fund Volkerding's long-term efforts.
Open source mobile game controller iControlPad 2 has QWERTY keyboard
Product 3 LLC is in the midst of a Kickstarter campaign for its mobile gaming device, theiControlPad 2. With just under two weeks to go, the project has met over half of its $150k funding goal.Improving on the original iControlPad, the device includes a QWERTY keypad as well as a swivel-mount that clamps to your smartphone of choice. As demonstrated in the video above, the controller is expected to work with any app due to its open-source nature. The Kickstarter page for the iControlPad 2 lists Ouya and Raspberry Pi support in addition to a 12-14 hour battery life.[Thanks, Ashley!]
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.
Insert Coin: The Parallella project dreams of $99 supercomputers
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. Parallel computing is normally reserved for supercomputers way out of the reach of average users -- at least at the moment, anyway. Adapteva wants to challenge that with its Parallella project, designed to bring mouth-watering power to a board similar in size to the Raspberry Pi for as little as $99. It hopes to deliver up to 45GHz (in total) using its Epiphany multicore accelerators, that crucially, only chug 5 watts of juice under normal conditions. These goliath speeds currently mean high costs, which is why they need your funds to move out of the prototype stage and start cheap mass production. Specs for the board are as follows: a dual-core ARM A9 CPU running Ubuntu OS as standard, 1GB RAM, a microSD slot, two USB 2.0 ports, HDMI, Ethernet and a 16- or 64-core accelerator, with each core housing a 1GHz RISC processor, all linked "within a single shared memory architecture." An overriding theme of the Parallella project is the openness of the platform. When finalized, the full board design will be released, and each one will ship with free, open-source development tools and runtime libraries. In addition, full architecture and SDK documentation will be published online if-and-when the Kickstarter project reaches its funding goal of $750,000. That's pretty ambitious, but we're reminded of another crowd-funded venture which completely destroyed an even larger target. However, that sum will only be enough for Adapteva to produce the 16-core board, which reportedly hits 13GHz and 26 gigaflops, and is expected to set you back a measly $99. A speculative $3 million upper goal has been set for work to begin on the $199 64-core version, topping out at 45GHz and 90 gigaflops. Pledge options range from $99 to $5,000-plus, distinguished mainly by how soon you'll get your hands on one. Big spenders will also be the first to receive a 64-core board when they become available. Adapteva's Andreas Olofsson talks through the Parallella project in a video after the break, but if you're already sold on the tiny supercomputer, head over to the source link to contribute before the October 27th closing date.
GNOME 3.6 arrives with new notifications and improved accessibility support
The third update to the third version of Gnome may send numerologists to their calendars, but we're not that way inclined. Instead, the latest bump to the software adds a new Boxes application, a new notification system and an activities overview. It's also chucking in improved accessibility support in addition to the usual raft of tweaks and bug fixes you'd expect from an update like this. It'll be available from your own vendor (or distribution) soon, or you can pick up a live image from the official site straight away.
Steam for Linux entering private beta in October for just 1,000 users
Next month, Valve is inviting 1,000 fortunate gamers to take part in the first external beta test of Steam for Linux. The trial includes the service itself and one game (which we're taking to be Left 4 Dead 2) that'll run on systems running Ubuntu 12.04 and above. Users won't get their hands on any other Valve titles, or Big Picture Mode, and the company is asking that only experienced Linux users get in touch -- novices are politely asked to wait for a subsequent release. It'll offer up details of how to sign up shortly, and given the love for the Valve's other products, we suspect it'll be a little oversubscribed.
NVIDIA to offer up documentation for Tegra graphics core to prove its commitment to open-source (video)
There's nothing like a little smack talk to light the fire under certain derrieres. It's been a few months since Linus Torvalds got verbal about NVIDIA's support for the semi-eponymous OS, prompting the chip-maker to say "supporting Linux is important to us." Proving that its word is good, NVIDIA will be releasing programming documentation for its Tegra architecture graphics core. The news comes from a talk given by Lucas Stach of the Nouveau project (who develop free drivers for the NVIDIA platform) at the XDC2012 conference. The focus will initially be on Tegra's 2D rendering engine, but it's hopes the 3D will soon follow. So, while Torvalds' approach might have been a little bit brusque, you can't fault its effectiveness. Video of the XDC talk after the break.
