The BBC interviews Torvalds. I like this bit: "For me, Linux on the desktop is where I started, and Linux on the desktop is literally what I still use today primarily - although I obviously do have other Linux devices, including an Android phone - so I'd personally really love for it to take over in that market too. But I guess that in the meantime I can't really complain about the successes in other markets." Linux on the desktop is quite passe. Phones and servers is where it's at.

"As the Linux desktop increases in popularity, the user interface experience has become increasingly important. For example, most laptops today have multitouch capabilities that have yet to be fully exposed and exploited in the free software ecosystem. Soon we will be carrying around multitouch tablets with a traditional Linux desktop or similar foundation. In order to provide a high-quality and rich experience we must fully exploit multitouch gestures. The uTouch stack developed by Canonical aims to provide a foundation for gestures on the Linux desktop."

Lennart Poettering, the author of systemd, has announced: "I just put a first version of a wiki document together that lists a couple of easy optimizations to get your boot times down to 2s. It also includes a list of suggested things to hack on to get even quicker boot-ups."

Liuns Torvalds is a finalist for this year's Millenium Technology Prize, prompting Scott Merrill with TechCrunch to do an e-mail interview. Interesting how Torvalds ignores the existence of ultrabooks - the Air is the exact same Intel-designed machine. Curious.

VectorLinux is one of those useful but lesser-known Linux distros. It's been around since 1999 and I've used it since 2006, off and on, in the role of a secondary OS. Now, with the disruptive changes Ubuntu forces on its user base with each new release, I've found myself increasingly attracted to Vector's stability and convenience. This article introduces "VL" to those who may not be familiar with it.

I don't actually have a reason for trying to build a Linux kernel with the CONFIG_PREEMPT_RT patch set. There's no way I can even measure the impact of it. Still, I felt like having a "real-time" Linux box, and set out to make one. Little did I know how difficult it would be to even get started.

After more than one year of development, the 4th version of the SCHED_DEADLINE Linux scheduler has been submitted to the kernel community. Besides taking into account prior comments and observations, this version improves the handling of rq selection for dynamic task migration and has native integration with the PREEMPT_RT project (although a patch for the standard mainline kernel is provided as well). The official development has been moved to a GitHub repository.

"Over a thousand developers contribute code to any given Linux kernel release. It's a process that works well from a technical perspective, but it's also one that has its fair share of shortcomings. In a panel at the Linux Foundation Collaboration summit this week, top Linux kernel developers detailed their common pet peeves about the Linux development model. It's a model that is not for the feint of heart ."

"Scientific Linux is an unknown gem, one of the best Red Hat Enterprise Linux clones. The name works against it because it's not for scientists; rather it's maintained by science organizations. Let's kick the tires on the latest release and see what makes it special."

"If you meet Linus Torvalds, he comes off as a mild-mannered, down-to-earth Finnish-American. He lives with his wife Tove, three kids, a cat, a dog, a snake, a goldfish, a bunny and a pet rat in a comfortable 6000 square foot home just north of Portland's tony Lake Oswego neighborhood. The house is yellow - his favorite color - and so's the Mercedes. But he's not really like any of his neighbors. He drives his Mercedes fast, slamming the car into gear and flooring it. There's no coaxing, no hesitation. Either the hammer is down, or the car is at rest. And he has an abnormal number of stuffed penguins on his mantle." Yup, sounds like the to-the-point Fin we all know and love.

"If you follow Arch Planet, you may have already heard the news that we are celebrating a decade of existence, with the release of 0.1 Homer on March 11, 2002. If you haven't already, grab some birthday cake and head over to Arch Planet to read several developers chronologies and wonderful words of praise for Arch Linux. There is also a brief article from The H Open Source as well as discussion on Reddit. With good fortune and a little luck, hopefully we'll be around to celebrate another 10 years!" Happy decade, Arch! My water cooker just pinged, so I'll drink the next cup of tea in Arch' honour.

The open source community should feel a little safer from software patent attacks, writes InfoWorld's Simon Phipps. "The Open Invention Network, a consortium of Linux contributors formed as a self-defense against software patents, has extended the definition of Linux so that a whopping 700 new software packages are covered, including many developer favorites. Just one hitch: The new definition also includes carve-outs that put all Linux developers on notice that Phillips and Sony reserve the right to sue over virtualization, search, user interfaces, and more."

Linus Torvalds on requiring the root password for mundane tasks. "So here's a plea: if you have anything to do with security in a distro, and think that my kids (replace 'my kids' with 'sales people on the road' if you think your main customers are businesses) need to have the root password to access some wireless network, or to be able to print out a paper, or to change the date-and-time settings, please just kill yourself now. The world will be a better place." Yes, it's harsh (deal with it, Finns don't beat around the bush), but he's completely and utterly right. While there's cases where it makes sense to disable certain settings (public terminals, for instance), it is utterly idiotic that regular home users have to type in their root password for such mundane tasks.

Linux 3.2 has been released . The changes include support for Ext4 block sizes bigger than 4KB and up to 1MB, btrfs has been updated with faster scrubbing, automatic backup of critical filesystem metadata, detailed corruption messages and tools for manual inspection of the metadata; the process scheduler has added support to set upper limits of CPU time usage to groups of processes; the desktop reponsiveness in presence of heavy writes has been improved; TCP has been updated to include an algorithm which speeds up slightly the recovery of connection after lost packets; and more. New drivers and small improvements and fixes are also available in this release. Here's the full changelog.
