  1. Re:manglement on Mars Phoenix Lander's Ovens Were Destined To Fail · · Score: 2

    That *might* be true, but if it were, you'd think they'd have been asked to conduct some real science, not focus on the golly-gee-whiz-we-found-ice aspect.

  2. manglement on Mars Phoenix Lander's Ovens Were Destined To Fail · · Score: 2, Informative

    Most of the comments so far are focusing on the oven door problems. Naturally, because that's what's mentioned in the summary and no one RTFAs.

    Anyway, the *much* more interesting revelation is that after the problems came up, the directive came all the way down from the top of NASA directing the mission scientists to change their plans. "At the end of June, word came down that the Phoenix team was to treat its next TEGA sample as its last, and to go after a sample of rock-hard ice before it did anything else. The Tucson team had lost its autonomy." After that, the team blew at least a month trying to meet this directive, and missed out on doing some of the basic science they wanted to do, just so NASA heads could trumpet feel-good publicity about having detected ice with Phoenix.

    Agreed, adoption is still pretty low, but it's definitely a game-changer. Surprisingly, SSDs might show up first en masse at the low end in netbooks like the Eee. Consider the lower power requirements and instant-on possibilities.

    Blood to squeeze? How about a new stone? Solid-state drives.

    SSDs. Yep, they will completely change the rules for filesystems. Decades of tricks and tweaking to deal with rotational latency and head movement have virtually zero application in SSDs. All the code for that will become worse than useless. It will have to be removed or at least turned off. Leaving it on will actually result in worse performance on SSDs.

  6. Re:The Text on Twenty Years of Dijkstra's Cruelty · · Score: 1

    Actually, Dijkstra spent a lot of time showing how to prove a program's correctness.

    He did. In fact, he spent more time proving the program correct than it took to write, test, run, debug, and fix, the program, and then the proof still has to be checked for correctness. I learned the Dijkstra techniques for proving code. Even something as painfully simple as proving a loop invariant holds and would terminate was mind-numbingly difficult and tedious, and still fails to be correct in the presence of concurrency. Somehow the program proof advocates lost sight of Gödel's incompleteness theorems. On top of being theoretically shaky, the technique is so wildly inefficient that the costs overwhelm the value almost before you get started. See the previous /. article, on how avoiding mistakes is a mistake.

    Cheaper in the short term, and the long term costs are difficult or impossible to see. As anyone who has been paying attention to economic news lately knows, it's all about the short term, and damned be the long term.

    There's no good economic or technical reason to keep these systems around -- the fact that they are still being used and patched is a reflection of office politics and managerial failures.

  17. Re:my choice on Practical Reasons To Choose Git Or Subversion? · · Score: 3, Insightful

    I also like the central server aspect, so that there is one place where the code is located, and I just have to keep that backed up.

    Nothing wrong with that, if it's effective for you and your team, and clearly svn wins out over git. Trying to make git within that model is just adding complexity without getting the benefits. If, in the future, you and your team decide you need to change how you do source control, then git, or some other distribute peer-to-peer system, might be the solution. But don't just use it as a drop-in replacement for centralized server development.

  18. not 1:1 on Practical Reasons To Choose Git Or Subversion? · · Score: 5, Interesting

    The most effective use of GIT happens when the team changes its mindset away from the central repository with multiple developers checking into it to a true peer-to-peer development team. I wouldn't switch away from svn until the organization I was with was prepared to "think different" and make that transition. Using GIT like a fancy svn just makes it like a complicated svn, not a better way of doing version control.

    From Wikipedia: "anyone who makes a false claim of infringement ... is liable for the damages suffered by the other parties, including legal fees."

    The law is very one-sided about it though, and recovering damages is prohibitively expensive. Oh yeah, there's also the fact that the law states that a counter-notification to restore the material must be sworn under penalty of perjury, unlike the original takedown notice, which just needs to be a good-faith attempt, with no criminal penalty for falsehood.
