It's Fedora release day! The Fedora project has pushed out version 13 of its cutting-edge Linux distribution. There's a whole boatload of improvements, some of which come from the wider Free software ecosystem, but of course, there's also a lot Fedora/Red Hat-specific stuff.

Over at Daringfireball this past weekend, John Gruber put words to what many people are thinking about after Google's rush of Android announcements and not-subtle Apple-bashing at this week's I/O conference: "all-out war." I agree with Gruber that a good old-fashioned bitter rivalry could be a great thing for the computing world, and for smartphone/handheld fans in particular.

InfoWorld's Neil McAllister takes on the old saw that open source doesn't innovate, highlighting seven innovative new ideas in software that you may be able to buy from proprietary vendors some day, but that you can only get for free from the open source community today. "Proprietary software vendors would have you believe that the open source movement has produced nothing but knockoffs of existing products and cast-off code that couldn't cut it in the free market," McAllister writes, "The open source movement remains a font of innovation to this day, and not just in the commercial sector. Numerous projects founded by universities, loosely knit communities, and individuals are exploring areas yet to be taken on by mainstream, proprietary software products."

"Back in February, Microsoft released public specifications for PST files, the databases used by Outlook for storing and archiving e-mail. To these specifications, Microsoft has now added a pair of developer-oriented open source projects: the PST Data Structure View Tool for cracking open PSTs to browse inside them, and the PST File Format SDK, a cross-platform C++ library for working with PST files programmatically."

So, we've talked a lot about Android last week due to Google's I/O conference, but what about the other guys competing in this field? Research In Motion, the Canadian smartphone maker, is hard at work developing version 6.0 of the BlackBerry operating system, and if a video of a pre-release build is any indication, they've still got some work to do.

Nero AG, a company with one of the most fitting names ever (can you imagine a company called Hitler or Stalin 2000 years from now?), has filed an anti-trust lawsuit against the MPEG-LA. The German technology company claims the licensing body has abused its monopoly power, and that is has not honoured agreements made with the US Department of Justice. There's some juicy stuff in here.

"Over the past year or so, Microsoft's robotics group has been working quietly, very quietly. That's because, among other things, they were busy planning a significant strategy shift. Microsoft is upping the ante on its robotics ambitions by announcing today that its Robotics Developer Studio, or RDS, a big package of programming and simulation tools, is now available to anyone for free."

"10 November 1972: CERN's Bent Stumpe places an order for 12 bowling balls for a total cost of 95 US dollars. Although not evident at first sight, he is buying the heart of some of the first tracking devices to be used in the SPS control room. Today, Bent Stumpe's device would be called a desktop mouse..."

"The first truly successful Microsoft Windows operating system is twenty years old today; Windows 3.0 was launched on the 22nd of May 1990 and was the successor to Windows 2.1x. The Graphics User interface (technically it was not an operating system) sat on top of MS-DOS and could run applications for the operating system from within a Window and many might fondly remember that it was available on 5.25-inch high density floppy disks. More significantly, it proved to be the perfect partner for Intel's then-new range of 386 processor, which bought protected mode and extended memory capabilities to the market."

This issue kind of fell by the wayside in all the WebM and Android violence, but apart from the cool things Google did this past week, they've also done something really bad. They claim it's a mistake, but the company has collected 600GB of data from open personal wireless networks in 33 countries through its Street View cars, prompting several countries to initiate official investigations into the search giant.

After god knows how many years, it's finally here: the final release of eComStation 2.0. We first reported on eComStation 2.0 back in December 2005, when the first beta was released, and between then and now, we've seen countless betas and release candidates come and go, but the wait is finally over.

Good news from the AROS world. Thanks to a bounty, they've been working on Gallium3D for a while, and the fruit of this work is starting to taste good. Part of this effort included a 3D driver for NVIDIA cards, and now a 2D driver, based on Nouveau, is being developed as well. This driver has reached beta status, and testers are needed.

There's an incredible amount of momentum behind Google's WebM Project. Opera, Mozilla, and of course Google will all include it in their browsers by default, meaning about 35% of web users will be able to use it with a minimal amount of fuss. On top of that, Microsoft has changed its previously announced plans to make HTML5 video in Internet Explorer 9 H264-only to include VP8 as well. Only Apple's opinion was unclear - until now.

Lightspark, the project that aims to create an LLVM-based Free Flash payer, has reached beta status. "JIT compilation of ActionScript to native x86 bytecode using LLVM; hardware accelerated rendering using OpenGL Shaders (GLSL); very good and robust support for current-generation ActionScript 3; a new, clean codebase exploiting multithreading and optimized for modern hardware. Designed from scratch after the official Flash documentation was released."
