People who think that userspace filesystems are realistic for anything but toys are just misguided
Apparently Linus has made another of his grand pronouncements, on a subject relevant to this project (thanks to Pete Zaitcev for bringing it to my attention).
People who think that userspace filesystems are realistic for anything but toys are just misguided.
I beg to differ, on the basis that many people are deploying user-space filesystems in production to good effect, and that by definition means they’re not toys. Besides the obvious example of GlusterFS, PVFS2 is almost entirely in user space and it has been used to solve some very serious problems on some seriously large systems for years. Everything Linus has worked on is a toy compared to this. There are several other examples, but that one should be sufficient.
So where does Linus’s dismissive attitude come from?

Will an HP WebOS License Deal Matter

Thunderbird jumps from 3.1 to 5.0 (just like Firefox's leap from 3.6 to 4.0 to 5.0)
Mozilla has number-creep on the brain. After dealing with Firefox 3.6.17's abrupt end of life in favor of 4.0, and then 4.0's deprecation in favor of 5.0 (and yes, I had to change repositories every time because Linux in general and Debian in particular doesn't force new software on users), now I learn that Thunderbird is jumping from 3.1 to 5.0.
Command-line Photographic Workflow on Linux
Most Linux photographers use graphical applications like digiKam, Rawstudio, or darktable as their tools of choice for processing and managing photos. But it is possible to set up a photographic workflow built around command-line tools that can handle a wide range of photographic tasks.

Simulation and Strategy Game 'Bridge Construction Set' Now Available in Ubuntu Software Center
Bridge construction set (also referred as Pontifex II) is now available in available in Ubuntu Software Center under the purchase section. The game which tests your bridge constructions skills has received great reviews from critics and users and has won many awards. Released back in 2002 and developed by Chronic Logic, Bridge Construction Set is about designing and building bridges and then stress testing them to see how these creations hold up under pressure. When test vehicles pass over these bridges and make it safely across you know you've succeeded. If they plummet into the river you know you need to go back to the drawing board. So, you must build a bridge that doesn't break in any condition, although breaking and plunging a train into the watery depths can be half the fun.

TLWIR 6: What City Is Your Distro?
Which GNU/Linux distribution a person prefers is a very individual choice. Some people like distributions that give them total access: the freedom to do whatever they want. Others want a desktop OS that will hold their hand if they run into problems. There is no single distribution that provides all of the right answers; each GNU/Linux user has to find the operating system distribution that best meets their own needs. In this week’s TLWIR, I will look at some of the best GNU/Linux distributions with a unique twist: I will compare the distribution to the city that I think most embodies its fundamental spirit.

What's This “…And the Rest” Crap!?!
Famously, the Gilligan's Island theme song, in its first season, left out mentioning the Professor and Mary Ann characters by name, simply including the "…And the Rest" in that lyric where their names later were heard. Mystery Science Theater 3000 even spoofed this issue during screening of This Island Earth, in which the actor Russell Johnson (The Professor) appeared. When Johnson first appears on screen while viewing This Island Earth, MST3K's Mike says over the film: "Hey, what's this "…And the Rest" Crap!?!". Indeed, what's that all about?
Sony CEO blurs line between Linux and piracy at shareholders’ meeting
Sony CEO Howard Stringer told shareholders that his company was the target of hacker attacks in April “because we tried to protect our IP (intellectual property), our content, in this case videogames.”
In April Sony was forced to take its PlayStation Network (PSN) offline for several weeks after hackers broke in and stole information from more than 70 million user accounts, finally relaunching it in May. A similar attack also affected Sony Online Entertainment (SOE) servers, which control Sony’s online role-playing games. Combined, more than 100 million user accounts were affected.

Oracle Solaris 11 to abandon elderly servers
Sun sets on UltraSparc I through IV+
Oracle is putting the finishing spit and polish on its impending Solaris 11 Unix operating system, but if you're hoping to plunk it on some vintage iron – or even some machines that are really not so old at all – you're going to be disappointed.…

Checksumming Files to Find Bit-Rot
In a previous article extended file attributes were presented. These are additional bits of metadata that are tied to the file and can be used in a variety of ways. One of these ways is to add checksums to the file so that corrupted data can be detected. Let's take a look at how we can do this including some simple Python examples.
MCSE or RHCE - Which certification should you be the most proud of?
Almost any IT related job requires interacting with an operating system at some point, and between them Windows and RedHat Linux cover a large portion of the market.
Obviously your choice of certification will depend largely on the equipment you are working with, but with that disclaimer aside, which certification is should you be most proud of?
