    the first few paragraphs are insightful, the rest - /. bashing - may be worth a discussion, but keep it factual. There's no need to attack editors.

    From the article:
    Yet for all its success, Slashdot remains very much unknown because it targets the niche of technology-savvy, highly-educated computer users. The vocabulary in most discussions is so technical that it constitutes another language. But a review of the occasional posts which discuss current events grounded in familiar issues and terms reveals a highly functional system that achieves high levels of feedback, interaction, and freedom, but still maintains a high level of insight and information in its content.
    /. remains unknown? Are there really famous websites apart from google or yahoo? IT people know /., people from xy know their local websites, but there are not that many Bruce Willis in the www.

  3. Re:Hoovy aka Trilobite java applet on New Electrolux Trilobite 2.0 Vacuum Robot · · Score: 1

    Well, that's the whole point of "comparable/incomparable" in the "AI" name. I didn't like the idea, but my professor wanted that the "hoovy" knows where the dust is if it's in a neighboring cell. So I built a FSM.
    When I was finished with the FSM, I wanted to build a more realistic, Trilobite-like hoover that doesn't know if there's no dust left, but builds internally a map of the room (A*). This version should stop only, if the whole room was vacuumed ("incomparable"). Then again, I still wanted to please my professor and built a A* method that stopped when there's no more dust left to compare it with the FSM version.
    Of course the A* version is not what Trilobite does, but it's a start.

    Anyone else having problems viewing this pdf in linux? A large part of the pdf is completely black in Xpdf and kghostview. In fact, it does the same thing in Acrobat reader 4 through cxoffice. What gives?

    Works with Adobe Acrobat Reader 6.0 (no black areas).
    Jaws PDF Editor Version 2.1 is readable, but the rectangle around the periodic table is black instead of white.
    I thought the newest version of Jaws PDF Editor was Acrobat 6.0 compatible, strange.

    This was my first (and last) Java Applet. JRE 1.4.1 required: Have fun :)

  10. SQL Injection in PHP on PHP and SQL Security · · Score: 5, Informative

    AFAIK SQL injection can be prevented by binding the parameters to the SQL statement and not putting them within SQL.
    An example:
    It's easy to inject some malicious SQL when using the following PHP code:
    mysql_query("INSERT INTO FOO('Bar') VALUES('$some_post_param');");
    But if you prepare the SQL statement with parameters and bind the variable $some_post_param to the statement, it will be secure.
    see mysql manual for mysqli_stmt_bind_param() aka bind_param
    $stmt = $mysqli->prepare("INSERT INTO CountryLanguage VALUES (?, ?, ?, ?)"); $stmt->bind_param('sssd', $code, $language, $official, $percent);

    I know this concept from Perl DBI, but in PHP I haven't seen anyone (phpBB, ...) using bind_param. Why is this? Performance? Keeping the code short and simple?

    As for general webserver security: use PHP and perl as cgi, use suEXEC, run the webserver as nobody/www, put the users into chroot jails, but by all means, don't use PHP safe_mode On.

    while most answers to the question make some valid points, they don't apply to the question :) the answer from imadork (226897) is the only one pointing out the main difference: The new chip from Strech + its compiler translate the functionality of your (c++, ...) code into hardware.

    And what about the official 3d tracking (macromedia 3d shockwave app, looks great)?
    How do you manage to view it? I tried, but it seems to require some plugin that does not exist. Or, well, it exists but only for Microsoft's and Apple's OSes. Which seems pretty silly if the target audience is people with an interest in technology. :-O (OK, so I know there are geeks on OS X, but they're a small minority as far as I can tell.)

    don't know of any official shockwave plug-in for linux, sorry. but there are ways, google it.

    Hmm, I don't know how you got that information, but their status page indicates that no-one has started, as of yet (5:10am in Barstow). The race is supposed to start at 6:30am, so that would make sense. Maybe they had some incorrect data initially. Anyways, this slightly 'lighter' page [grandchallenge.org] shows the status.
