  1. Re:Not a bug on Apps That Rely On Ext3's Commit Interval May Lose Data In Ext4 · · Score: 4, Insightful

    UNIX filesystems have used tiny files for years and they've had data loss under certain conditions. My favorite example is the XFS that would journal just enough to give you a consistent filesystem full of binary nulls on power failure. This behavior was even documented in their FAQ with the reply "If it hurts, don't do it."

    Filesystems are a balancing act. If you want high performance, you want write caching to allow the system to flush writes in parallel while you go on computing, or make another overlapping write that could be merged. If you want high data security, you call fsync and the OS does its best possible job to write to disk before returning (modulo hard drives that lie to you). Or you open the damn file with O_SYNC.

    What he's suggesting is that the POSIX API allows either option to programmers, who often don't know theres even a choice to be had. So he recommends concentrating the few people who do know the API in and out focus on system libraries like libsqllite, and have dumbass programmers use that instead. You and he may not be so far apart, except his solution still allows hard-nosed engineers access to low level syscalls, at the price of shooting their foot off.

  6. Re:20 second explanation on Null References, the Billion Dollar Mistake · · Score: 1

    That's a misunderstanding of the spec. NULL has no type, so evaluating NULL = 1 results in an unknown. That does not imply that NULL is an unknown value.

    So there's known knowns, known unknowns, and then there's NULL.

    I'm sure it doesn't help things that Stroussoup made this explicit in C++. So if your view is that C is a subset of C++, you'll get these trivia wrong. Unfortunately, C and C++ will penalize you for getting trivia questions wrong with great zeal.

    (And in reading your link, I don't see where it claims that NULL is implementation defined. Perhaps you can offer a more specific citation?)

  8. Re:ARM Netbook on New Netbook Offers Detachable Tablet · · Score: 1

    I dual boot vista and ubuntu+1. I don't know the specifics of Vista's software, but I do know that 1) it's trainable and 2) it uses neural nets. In a sense, they use software to slice up a sentence you wrote into characters to reduce the problem to what CellWriter solves. I've noticed that their system works better in cursive, where they pretty much know where words begin and end.

    Cellwriter also considers stroke order, as well as a number of factors like average distance from trained glyphs. This doesn't really help a lot with English, but lots of people seem to think it could work well with Asian character sets, where there's an established stroke order.

  9. Re:ARM Netbook on New Netbook Offers Detachable Tablet · · Score: 1

    One of the things I do is spend a little freetime watching over tablet support in Ubuntu (if you like I can catalog recent improvements). I agree with you that Vista is currently a best of breed online handwriting recognition. In some sense I respect Microsoft's efforts here. Handwriting recognition takes a lot of time to design, analyze, and tune; very academic in nature. They've gone the extra mile and integrated the technology into something deployed.

    One of the challenge Linux faces is moving academic research into deployed software. Lots of CS is published without source. In many areas, it's sufficient to publish the algorithm; but with statistical recognition, where there isn't necessarily a "right" answer, small tweaks can make make or break it. Additionally, academics sometimes abandon their research after publication, as there's little incentive to continue maintaining a program intended as a proof of concept. "Published and done, time to move onto the next grant!"

    As an example, the best Linux handwriting program I know about is CellWriter; an honors undergrad student wrote and published it. It works well for what it is, but now that the semester's long over, there's not a lot of work being done on improving it, especially now that the author is in grad school and working on various other projects.

    What angers people though is the routine denials of claims. I don't think its right to reject ambulance fees when you're injured with a compound fracture (this happened to my little brother); did they expect him to walk to the emergency room?

  12. Re:This is the litte formula on Industry Open-Sources Model For Infamous CDS · · Score: 3, Interesting

    Well, it's not the model that tanked AIG, it's that the contracts allowed AIG to write insurance with no capital reserves, because they were rated AAA. Of course, they're AAA because the have regular income from their insurance businesses, and access to capital markets, and were pretty damn big. This is stupid, because they went on to write as many contracts as big AAA rated company is allowed to.

    So many problems we have come down to credit ratings manipulation, that I'm ready to demand that they be shut down, and never relied upon. A credit rating is ephemeral and subject to violation of trusted 3rd parties; cash downpayments aren't.
