XFS Developer Takes Shots At Btrfs, EXT4

Software

Chris Mason of Btrfs fame wasn't the only Linux file-system developer talking to the public last week. While the Btrfs talk was going on in Los Angeles at SCALE 10x, Dave Chinner was down under in Australia at LCA2012 talking about XFS. His talk included some controversial shots at EXT4 and Btrfs.

During his Linux.Conf.Au 2012 presentation in Barratt, Australia, Chinner first talked about the XFS meta-data problems of the file-system's meta-data modification performance being terrible. EXT4 can be 20~50x faster than XFS with certain workloads like unpacking a Linux kernel source tar-ball package. However, with one major algorithm change and various performance optimizations, the XFS performance is now scaling much better (Dave recommends the Linux 3.0 stable series or newer for the best XFS support).

  • System76 wants to build its own hardware for its Linux-based computers
    System76 is building up quite a name for itself, being one of a very limited number of companies selling only computers running Linux-based operating systems. Now the aim is to branch out; System76 wants to design and build its own hardware, while representing the open source community as it does so. At the moment, the hardware used in System76 systems is outsourced, but in the future this will change. The company says that it is moving into phase three of its development cycle, and this "moves product design and manufacturing in house." And you should set your expectations high: "We're about to build the Model S of computers. Something so brilliant and beautiful that reviewers will have to add an 11 to their scores."
  • AppCenter Spotlight: Beta Testers
    Over the past month we’ve been beta testing the new AppCenter with a number of developers, from elementary OS contributors to backers of our Indiegogo campaign. After testing out the submission process and getting some apps into the store (and seeing rapid updates!), I wanted to take a moment to highlight some of the first apps.
  • elementary OS to get improved AppCenter, showing off a few new applications
    I have to hand it to the elementary OS guys, they have a massive focus on design and it does look quite incredible. It is easily one of the best looking Linux distributions, which I do admire. Their new AppCenter, for example, looks extremely clean and clear.

Beijing Zoo is No Place for Pandas

I am a Panda lover. I work as a support engineer in an I.T company here in the United Kingdom. Most of my spare time is spent watching different Panda videos -- both old and new videos. Basically, it is my therapy; a 'stress release' for me. I find them to be adorable and precious creatures. As a matter of fact, I would like to volunteer to come to Sichuan. I want to experience and feel what it's like to be a Panda keeper, to be able to interact with them for real. The Panda is China's National Treasure, so it's a shame to watch the Panda videos from Beijing zoo, as the place is disgusting and not ideal for Pandas to live in (and for sure for all the rest of the animals who unfortunately got stuck in this prison cell).

The place looks like a ghost town. Lifeless and languished. Knowing that Pandas wear a thick fur on their body, can you imagine what it feels for them in 30C or 35C (summer temperature)? What it probably feels like all the time? Come on, if you really care, you must do something now, otherwise these Pandas will die. Please bring them back to their sanctuary where they really belong.

Linux 4.11 File-System Tests: EXT4, F2FS, XFS & Btrfs

With the Linux 4.11 kernel potentially being released as soon as today, here are some fresh benchmarks of Btrfs / EXT4 / F2FS / XFS on a solid-state drive and comparing the performance of 4.11 Git back to Linux 4.9 and 4.10. For those wondering if the block/file-system changes of Linux 4.11 have any impact on EXT4/F2FS/XFS/Btrfs for common I/O workloads or how these file-systems are comparing on this latest kernel, here are some benchmarks.
