A Short History of Btrfs

Posted by Soulskill on from the new-and-shiny dept.

diegocgteleline.es writes "Valerie Aurora, a Linux file system developer and ex-ZFS designer, has posted an article with great insight on how Btrfs, the file system that will replace Ext4, was created and how it works. Quoting: 'When it comes to file systems, it's hard to tell truth from rumor from vile slander: the code is so complex, the personalities are so exaggerated, and the users are so angry when they lose their data. You can't even settle things with a battle of the benchmarks: file system workloads vary so wildly that you can make a plausible argument for why any benchmark is either totally irrelevant or crucially important. ... we'll take a behind-the-scenes look at the design and development of Btrfs on many levels — technical, political, personal — and trace it from its origins at a workshop to its current position as Linus's root file system.'"

      Poor guy, he could have been first , if not for the long post .

      We could implement a locking system , so that no one can start posting until the first person to begin writing posts . That way, it doesn't matter what you write , you will be first if you start first.

      It may also lead to more interesting first posts , as the writers won't be stressed that they won't have a first post.
      Offcourse , we need to implement a sort of timeout , to prevent locking the thread in case the first poster decides not to post.

      No, it's not - but you're wrong. :"Linus's" is correct. The 's' after the apostrophe only gets dropped in plurals.

      The Revelation of Saint Slasher Dotter, chapter 12, verse 19, says, "Verily, in the deepest dungeons, there is a place reserved for grammar nazis. There shall be weeping and gnashing of teeth, as the grus gnaw upon the bones of the grammar nazis for all time. Lo, there shall be no death, no resets or restarts for the grammar nazis, nor will there be relief for them in the lakes of fire. Beware, grammar nazi, or you shall feed the gru!"

    Well good for you. I've had an entire HD decide that moving files to another drive, while deleting other files, meant that I wanted the entire filesystem hosed.

    Let us all get this straight. AC would reject any and all medical knowledge that resulted from experimentation by the Nazi's during the second world war. Going a step further, he might wish to have any medical knowledge gained by the allies during WW2 purged from human knowledge. After all, such knowledge is "tainted", because it was motivated by violence.

    If it can't be patented and commercialized it can't be much good.

    Don't anyone inform AC that there is no patent on his arse, or his reproductive organs. He'll be removing them as "junk".

    Don't anyone inform AC that there is no patent on his arse, or his reproductive organs.

    AFAIK there are many patents on human genome, and thus his arse and reproductive organs would, in fact, be patented as derivative works. Furthermore, said reproductive organs would also qualify as a patent violation facilitation device (unless he has a license from patent holders), and thus possession of said organs would imply that he intends to break patent law - and of course his mere existence proves that his parents already did.

    Disgusting criminal scum, his like drags the quality of this site down.

  7. Val Aurora? by RaymondKurzweil · · Score: 0, Offtopic

    So I wondered if Val Henson had ended up getting married. And I was going to use the opportunity to make a lame remark (Slashdot calibre) and advise her to try not to kill her husband (filesystem design can be stressful). But it turns out she just has daddy issues.

    Whatever.
