Linux at 20: New Challenges, New Opportunities

InfoWorld's Neil McAllister examines the challenges and opportunities ahead for Linux as it enters its third decade, and finds that the rise of cloud computing and mobility could elevate the open source OS to a level of unprecedented dominance. 'The last 20 years haven't always been easy. Linux has made a few enemies, Microsoft foremost among them. It has faced its share of challenges, too, both technical and legal, and there are more hurdles ahead. Nonetheless, as Linux enters its third decade, its opportunities have never been greater. Computing is changing, and Linux is not only benefiting from this change but is enabling it. Thanks to a shift beyond the PC, Linux is poised to become more than just an OS, but one of the most transformative forces in computing history — and it's happening right under everyone's nose.'

Two Years With Linux BFS

This month marks the two-year anniversary of the release of BFS, the Brain Fuck Scheduler, for the Linux kernel. While BFS has not been merged into the mainline Linux kernel, the scheduler is still actively maintained by Con Kolivas and patches are updated for new kernel releases. The BFS scheduler has also reached mild success and adoption over the past two years. In this article is a fresh look at the Brain Fuck Scheduler along with a fresh round of benchmarks from the Linux 3.0 kernel.

A Linux Distribution from the US Department of Defense

"Lightweight Portable Security (LPS), created by USA's Department of Defense, is a small Linux live CD focusing on privacy and security, for this reason, it boots from a CD and executes from RAM, providing a web browser, a file manager and some interesing tools. LPS-Public turns an untrusted system into a trusted network client." Complete with backdoor so they can spy on all of us I'm sure!1!!

Linux 3.0 Released

Linux 3.0 has been released. Technically, the release of version 3.0 of the Linux kernel shouldn't be too eventful, since the jump in version number doesn't actually signify any huge change or whatever; the only reason behind the bump to 3.0 is to come to saner version numbering. Still, man, it's like, totally version 3 of the Linux kernel.

Damn Small Linux: Still Damn Fun

I've described how to refurbish mature computers in several articles. The emphasis has been on machines in the four to ten year old range -- Pentium IV's, D's, M's, III's and Celerons. But what if you have a really old computer, like a Pentium II, I, or even a 486? Can you use it for anything worthwhile? A vintage distro named Damn Small Linux answers "yes." This article describes DSL and tells how to make 1990's computers useful again. Screenshots follow the article.

Interview: Lennart Poettering

Linux.FR has an interview with Lennart Poettering of PulseAudio and systemd fame (among others). Regarding PulseAudio: "I can understand why people were upset, but quite frankly we didn't really have another option than to push it into the distributions when we did. While PulseAudio certainly wasn't bug-free when the distributions picked it up the majority of issues were actually not in PulseAudio itself but simply in the audio drivers. PulseAudio's timer-based scheduling requires correct timing information supplied by the audio driver, and back then the drivers weren't really providing that. And that not because the drivers were really broken, but more because the hardware was, and the drivers just lacked the right set of work-arounds, quirks and fixes to compensate for it."

Object-oriented Design Patterns in the Kernel, Part 2

"In the first part of this analysis we looked at how the polymorphic side of object-oriented programming was implemented in the Linux kernel using regular C constructs. In particular we examined method dispatch, looked at the different forms that vtables could take, and the circumstances where separate vtables were eschewed in preference for storing function pointers directly in objects. In this conclusion we will explore a second important aspect of object-oriented programming - inheritance, and in particular data inheritance."

Adobe Drop Linux Support for Adobe AIR

In a blog post today, Adobe's Director of Open Source and Standards said: "we will be focusing on supporting partner implementations and will no longer be releasing our own versions of Adobe AIR and the AIR SDK for desktop Linux". McAllister says that "way back in 1999" he'd predicted "a significant market for desktop Linux by 2005. Obviously I was wrong. So we, Adobe, also need to shift with the market." Source code for AIR will be made available to partners so they can make their own Linux implementations if they so desire. Is there anyone in the audience who cares about no more AIR on Linux from Adobe? Anyone...?

KQ ZFS Linux No Longer Actively Being Worked on

"Remember KQ Infotech? KQ Infotech was the Indian company that ported the ZFS file-system to Linux as an out-of-tree kernel module (after deriving the code from the LLNL ZFS Linux work) and KQ's interesting methods of engagement in our forums. The company was successful in delivering an open-source ZFS module for Linux that performed semi-well and didn't depend upon FUSE (the file-systems for user-space module) like other implementations. However, this ZFS Linux code appears to no longer be worked on by KQ Infotech."

Linux Kernel 3.0 Announced to No Fan Fare

Well this makes a change. Linus Torvalds has announced that the next version of the Linux Kernel release is to be '3.0'. "I decided to just bite the bullet, and call the next version 3.0. It will get released close enough to the 20-year mark, which is excuse enough for me, although honestly, the real reason is just that I can no longer comfortably count as high as 40."

0install 1.0: Cross-Distribution Packaging

Zero Install, the decentralised cross-distribution software installation system, announced 0install 1.0 today, after 8 years in development. 0install allows software developers to publish programs directly from their own web-sites, while supporting features familiar from centralised distribution repositories such as shared libraries, automatic updates and digital signatures. It complements, rather than replaces, the OS's package management. As well as allowing developers to create a single package that works across Linux, BSDs, Mac OS X and Windows, it could help make software available on more minor platforms. OSNews covered decentralised installation systems in 2007.

End of Linux 2.6 Kernel; to Start Afresh From 2.8

"So far. we have seen 39 development cycles of Linux 2.6 and the 40th is about to start. However, Linux 2.6.39 might be the end of the Linux 2.6 series. In an email, Linus Torvalds wrote that the numbers are becoming too big and he might thinking of giving the next release a version number of 2.8.0. In the ensuing discussion, Torvalds wrote that a version number of 3.0 is also a strong possibility", as a natural way to introduce a new numbering scheme where odd numbers are also used for stable releases and feature releases increment the second digit.
