  1. N2H2 (Bess) filtering facts... on N2H2 Drops Plans to Sell Student Web-Browsing Information · · Score: 2
    Some facts about Bess filtering:
    1. Bess does not filter by keyword, except for search engine queries and results. They filter by site URL.
    2. For the "el-cheapo" service offered to schools, there are only a few combinations of categories available. I've posted a recent copy of their list at: http://pillars.net/~bobv/N2H2/categories.html
    3. Bess catches a lot of flak for inaccurate filtering becase people assume that if a site is blocked, it's because Bess thinks it is porn. Porn is only one of the 42 available categories. Another is "Free Pages", which is on the default blocking list for schools. Reason for that is free webhosting sites change so frequently that they can't hope to keep up with them all, so you get the option of just blocking them in their entirety.
    4. Since Bess is a proxy service, your local network administrator should be able to allow exceptions to the filter. If you use Squid, the relevant keyword is "AlwaysDirect".

    Dunno. I really liked it too, and I even read the book *first*. But then, I've never seen a Robin Williams movie that I didn't like. (Though I didn't particularly care for Mork&Mindy.)

    Of all the movies I've seen in my lifetime that were based on books rather than screenplays, I'd say this one ranks about fourth or fifth as to how well it preserves the flavor and plot of the original story.

    Sure, they through in a little sex, and sure it was juvenile. But hey, Hollywood *will* be Hollywood.

    Well, I've got 1000kbit DSL, not "several 100Mbit interfaces". I suspect that many of the "enterprise-level" commercial firewalls would also fail your test.

    Point is, I was able to cobble together something reasonably efficient for my purposes in less than an hour, including research and bugfixing. And I'm not a particularly talented coder.

    Just out of curiousity, though, could you post a link to some documentation about the "ip rule" command and "rt-netlink" ? Never worked with either one.

    True, it was a quick hack. I used open() out of habit for portability, but that's a moot point here, eh?

  6. Re:Iptables, user-space queueing, and reiserfs on Why iptables (Linux 2.4 Firewalling) Rocks · · Score: 1

    Actually, I use file contents for the reason why it's blocked. So when I review my /var/log/kern.log and see a bunch of denied messages for the same IP, I look at the contents of that file to see how serious the issue is.

  7. Iptables, user-space queueing, and reiserfs on Why iptables (Linux 2.4 Firewalling) Rocks · · Score: 4

    I needed to block a list of thousands of ip addresses at the firewall. Here's how I did it:

    First, I read the sample code for how to implement user-space queueing. That's where you pass a packet to a user-space program so it can decide what to do with it. Then I made some trivial changes to that program so that it looks for a file in a certain directory with a name equal to the IP address in the packet header.

    If the file exists (i.e. an open() call succeeds), then the packet is denied; otherwise it is allowed. Anytime I want to add a new IP address to the blocking list, I just create a file in that directory. Since I run reiserfs, the test for file existence is as efficient as a hashtable lookup, but much simpler to code.

    Not as sophisticated as a commercial firewall program, but not as much overhead, either. (Simplistic) benchmarks show no significant increase in network latency. Works for me!

    Have you ever tried to *buy* a certificate from any of those non-verisign CA's ???

    I chased them all down last year (things might have changed since then) and there were exactly two (Verisign and Thawte) that offered certificates to the general public and weren't reselling certificates issued by one of the other CA's.

    what if your an ISP and your customers demand less spam?
    That's like asking the postal service to deliver less junk mail.

    No, because:

    1. The spammers have to PAY the postal service to deliver their mail. This alone tends to limit the level of abuse.
    2. The postal service doesn't worry about you switching to a different delivery service.
    3. The courts provide specific remedies in the case of postal mail-abuse, including the right to have your name taken off the list, the right to know how they obtained your information, and the right to collect punitive damages in the case that your requests are ignored.
    4. Delivery of junk-mail does not prevent delivery of legitimate mail, even if your mailbox is full.
    5. The post office does not send you a monthly bill for the right to receive mail.

    In short, any analogy comparing a sender-funded message service with a recipient-funded message service is poor logic.

  18. Re:probing dreamcast perfs. on Dreamcast Runs Linux · · Score: 1

    I was wondering this too, and researching the answer when Netscape 4.76 vaporized, taking my accumulated notes with it.
    (sigh)
    Anyhow, it runs a Hitachi SH-4 processor at 200 Mhz, which according to one source (Won't look up the link again for fear of re-vaporization) specs at 360 MIPS and 1.4 GFLOPS. Apparently, it's of the same heritage as the Sun SPARC processors. You won't find a bogomips rating because the author of the port had to comment out the bogomips testing code in order to get the kernel to compile.
    Do a Google search for "Dreamcast Bogomips" and "Hitachi SH-4" and you'll find plenty of info. However, based on previous experience on an UltraSparc with probably double the performance, I'd say about one kernel per hour, YMMV.

  22. High entry-level, no promotion... on Higher Pay For U.S. Federal Computer Jobs · · Score: 2

    The government (at least in my area) is willing to hire tech workers with much less documentable experience than private contractors. Once you're in, they'll let you take on as much as you can handle, but there's absolutely no incentive for you to do so.

    In a nutshell, the best way to take advantage of the situation is to get hired in, get as much experience and training as you can for the first year or two, then get the heck outta there before laziness sets in.

    The NAF entity I work for bleeds talent like crazy. They're afraid to develop anything new in-house, because they know that anybody good enough to do the job won't be staying for long.

    I'm on my second government job. Looking forward to the end of my first year when I can start sending out resumes to private industry again.

    I'd like to respond to all of the poor suckers who assume that public transportation is somehow "cheaper" or "more "efficient" than private transportation. Most of them are in this thread, so here goes.

    It isn't.

    Don't believe me? Check your figures. Ask your local bus driver or subway attendant just what percentage of their company's operating expenses are covered by fares.

    It's almost certainly less than ten percent.

    Probably MUCH less than ten percent.

    Then figure out what your fare would be if it wasn't government-subsidized.

    Then figure that it probably costs between 20 and 50 cents a mile if you used private transportation (your old beater) rather than public transportation.

    Then drive your old beater. It's cheaper any day of the week. Even in New York.

    The fact is, that the socialists (the REAL socialists: the policy-makers) don't want to rub noses with the masses, so their "solution" to the "traffic congestion problem" is to put all you poor people on the bus, so they get most of the roads to themselves.

    So what if it costs more? They'll just raise the taxes until they cover the operating expenses.
