Roll Your Own Toy UNIX-clone OS

"This set of tutorials aims to take you through programming a simple UNIX-clone operating system for the x86 architecture. The tutorial uses C as the language of choice, with liberally mixed in bits of assembler. The aim is to talk you through the design and implementation decisions in making an operating system. The OS we make is monolithic in design (drivers are loaded through kernel-mode modules as opposed to user-mode programs), as this is simpler."

Whamcloud Building New Lustre Distro

"The open source Lustre technology is a parallel file system that is often found in high performance computing (HPC) environments. Users of the file system will soon get a community Lustre distribution , thanks to the leadership of startup Whamcloud. The reason why Whamcloud is building a Lustre distribution isn't about creating a fork from Oracle, but is about helping to support and expand the Lustre community."

Mozilla, RSS and Feedback

A mini-tempest has been raging across the web with anger at Mozilla for removing the RSS icon from the Firefox 4 toolbar by default (and moving it to the bookmarks menu). This has been going on for a couple of weeks now, and I had avoided writing about it on OSNews since the recent furore is often cited to have begun around a personal blog post I wrote, but now things have come to an impasse: "No matter how loudly you shout, what you see in the beta with regard to the feed auto-discovery button is what will ship in Firefox 4". When Mozilla can say they are open to input, but refuse to change in the face of near universal disagreement, we all lose, not just me.

No Hardware Acceleration Firefox for Linux Due to Buggy X Drivers

Yesterday, the ninth Firefox 4.0 beta was released. One of the major new features in Firefox 4.0 is hardware acceleration for anything from canvas drawing to video rendering. Sadly, this feature won't make its way to the Linux version of Firefox 4.0. The reason? X' drivers are "disastrously buggy". Update: Benoit Jacob informed my via email that there's some important nuance: hardware acceleration (OpenGL only) on Linux has been implemented, but due to bugs and issues, only one driver so far has been whitelisted (the proprietary NVIDIA driver).

Google: H.264 Stifles Innovation

I didn't plan on this, but there's really nothing I can do. Unless you want me to write about the upcoming ten billionth download from the iOS App Store, you'll have to settle for this. On the Chromium blog, Google has clarified its decision to drop H.264 support from the Chrome web browser, and in it, Google basically repeats the things that those concerned about the future of video on the web have been saying for a long time now: H.264 on the web kills innovation.

Microsoft, Opera’s Haavard Respond to Google’s H.264 Move

And the fallout from Google's decision to drop H.264 support from its Chrome web browser continues to fall. Opera's Haavard - speaking on his own behalf - slammed the article which appeared on Ars Technica earlier today, while Micrsoft's Tim Sneath likened Google's move to the president of the United States banning English in favour of Esperanto. Also within, a rant (there's no other word for it) about the disrespect displayed by H.264 proponents towards the very open source community that saved and invigorated the web.

Why Russia, China, and Iran Love Linux and Open Source

"At the end of 2010, the 'open-source' software movement, whose activists tend to be fringe academics and ponytailed computer geeks, found an unusual ally: the Russian government. Vladimir Putin signed a 20-page executive order requiring all public institutions in Russia to replace proprietary software, developed by companies like Microsoft and Adobe, with free open-source alternatives by 2015."

The Open-Source ATI Driver Is Becoming a Lot Faster

"Now that the kernel mode-setting page-flipping for the ATI Radeon DRM kernel module has been merged into the Linux 2.6.38 kernel and the respective bits have been set in the xf86-video-ati DDX, we're in the process of running new open-source ATI graphics benchmarks under Linux. Our initial results (included in this article) show these latest improvements to cause some major performance boosts for the open-source ATI driver as it nears the level of performance of the proprietary Catalyst driver."

Extensive Benchmarks of Amazon’s EC2 Compute Cloud

"Last month we delivered our first benchmarks of the Amazon EC2 Cloud, but those initial tests were limited to just a few of their cloud computing instances due to failures with the Ubuntu EC2 operating system on their other compute instances. Earlier this month we then showed how the Amazon EC2 Micro was comparable to a Nokia N900 and Intel Atom, but now we have a more exhaustive comparison complete of all major Amazon Elastic Compute Cloud types."

‘Dropping H.264 from Chrome a Step Backward for Openness’

"The promise of HTML5's video tag was a simple one: to allow web pages to contain embedded video without the need for plugins. With the decision to remove support for the widespread H.264 codec from future versions of Chrome, Google has undermined this widely-anticipated feature. The company is claiming that it wants to support 'open codecs' instead, and so from now on will support only two formats: its own WebM codec, and Theora." Sorely disappointed in Ars' Peter Bright. Us geeks reviled web developers for sticking to Internet Explorer when Firefox came onto the scene, and yet now, the same arguments we used to revile are used to keep H.264 in the saddle. How us mighty geeks have fallen.

38 Billion Spam Emails: a Sign of Things to Come?

Over the last twelve months, AppRiver quarantined more than 38 billion spam messages, almost double the amount quarantined just two years ago. Of that total, 450 million messages contained viruses. To make things even worse, phishing techniques showed increasing sophistication and are likely to be ever-present during this year. Also, the ZeuS botnet remains highly dangerous as it continues to target financial information while social networking sites continue to be the prime locations for cyber criminals to prey on the naive and unsuspecting.
