  1. The way out: "Prototyping Language" on Do Scripters Suffer Discrimination? · · Score: 2, Insightful
    Tell Management that the scripting language is being used only to quickly develop a prototype, and that then the prototype will be re-implemented in a "real language" later, with profiling tools used to determine the priority order of which modules get re-implemented first.

    Once the thing works, if it performs well enough, the resources to re-implement will dry up.

    Once enough of it has been done in a compiled language (that is, about 20%...remember the 80%/20% rule). resources to re-implement the rest will dry up.

    Soon Management will realize this new "Prototyping Paradigm" saves them resources, but gives them plenty of busy work (re-implementing scripts in compiled code) for when they need to look busy, and it will turn out to have been Their Idea All Along.

  2. Quota systems... on Ask ISP Owner Barry Shein About the Spam Wars · · Score: 2, Interesting
    So are techincal mechanisms feasable (like the following) or is United Nations level international legal enforcement required?

    My technical proposal: people/companies purchase SMTP message-sends the way they purchase cell-phone-minutes:

    • spammers who use open relays would saturate that relay's quota, and most of the spam thus relayed would fail to go out, thus the owner of the relay would have incentive to fix it, so they can send their own mail.
    • spammers who send directly from ISP accounts would have to purchase large numbers of them in order to send a given volume of mail.
    To enforce such a system, you would need to build a smart firewall that knew just enough SMTP protocol to read the RCPT To: lines, and count recipients. When a given sending host exceeds its counter for the week, poof! the firewall blocks further SMTP activity (or even all activity) from that host until someone clears it.

    Backbones could limit individual ISP's with such a system, and ISP's could in turn limit individual customers; indeed they would basically have to, so that one customer can't ruin their SMTP quota. If the ISP doesn't enforce such a rule, their backbone tap enforces it for them.

    If such infrastructure became widespread, the only way a spammer could send large numbers of messages would be to get large numbers of ISP accounts, which would hopefully cost them enough money to make it not worth their while anymore.

  3. Who wrote it? on Rick Berman Doesn't Know Why Nemesis Tanked · · Score: 1
    The answer should be obvious -- who wrote it? Apparently J.M. Dillard, Brent Spiner, and John Logan.

    Next time they need to get, say, Neal Stephenson, Vernor Vinge, Brian Sterling, or Orson Scott Card. Or maybe one of the folks who wrote good ones in the past, like Ellison.

    Then they might get some interesting story lines.

  4. Re:Why does NASA care? on Slashback: Intentia, Ephemera, Restoration · · Score: 1
    Alas, it is really quite simple:
    • NASA is funded by the US Congress
    • Congress is voted for by "The People"
    • "The People" get silly ideas
    So when enough folks get the idea that NASA is lying to them, they are willing to vote for people who advocate shutting down NASA.

    The frightening part is that it doesn't neccesarily need to be that *many* people who believe in the issue -- we have an almost exclusively two-party system here, which makes "swing voters" very powerful -- folks who will pick one candidate over another based entirely on one issue -- in other words "fanatics".

    So most people could not care less what your position on NASA is as a Congressional candidate. It doesn't even make the list, next to health care, economic policy, and whether you sleep around (sigh). But if a small group of fanatics will vote based on your position on NASA, and the election is close, voila, you the polititcian now have a position on NASA that helps get you elected...

    I suspect in Germany, which has a healthy multi-party system, these swing-voter effects are much weaker. But here in the USA, these relatively small groups who will vote entirely on single issues (abortion policy springs to mind as a good example...) get the major parties to take positions on that issue even though the swing-vote group is a single-digit percentage of the populace.

    Most people summarize their logs, so the raw logs last just long enough to get converted into fancy reports, and are then tossed.

    A summary that says how many hits each directory got, and what the top 10 referring URL's were, etc. is a heck of a lot smaller, and generally more useful, than the full, detailed logs.

  10. Replacement for SMTP -- ideas on ISP Chief on Spam · · Score: 2
    Real micropaments are hard to implement, and most users have already paid for a reasonable amount of email service.

    Instead, we need to have people use an authenticating protocol to send mail, and they should get issued a key/certificate/whatever with their e-mail account that lets them send,say, 500 emails a month. That email server is in turn issuead a certificate with a known signing authority.

    The problem is, how do you prevent a spammer from obtaining an arbitrary number of email server certificates? Commercial "authorities" like Thawte, etc. are not an answer; as many credit card numbers as you can get is as many certificates you can get. As long as you can send a few million emails before your certificate gets blacklisted, the cost per email for the ceritificate is trivial.

    The only answer I see is to hold all email for a day before delivery, and to have a distributed mechansim for counting email sent by each server. If a given server is sending spam-house rates of email, it gets (automatically) blacklisted, and all the email being held from that server gets deleted before its ever delivered.

    That's my Idea. What's yours?

    ALL largish companies do this (or something similar), not just MS and Intel. Insurance companies gobble up little comptetitors, fast food chains set up shop next to similar local business, Starbucks does the same.
    But in the case of monopolies like Microsoft, much of that becomes illegal. Even buying up direct suppliers of your competitors to shut off their supplies might be illegal. But the Microsoft/Intel trick is to buy up companies that make things that customers of your competitors buy to use with your product.

    This would be like Starbucks buying up Sweet-n-Low and reformulating the sweetner it so it makes any coffee but theirs taste horrible, then doing the same to Nutrisweet, then to sugar and dairy companies...

    This is the pattern that Microsoft and Intel both have repeatedly run through:

    • find a company whose software helps you develop software, or web pages, or what have you

  14. Re:All spammers on Another Millionaire Spammer Story · · Score: 2, Informative
    Seems to me the most practical tracking method would be embedding images in HTML email with encoded URLs.
    Actually, the ones I've seen lately put a CSS style sheet link into a multipart/mime with an HTML section. The URL for the stylesheet was of the form:
    http://mail.ecplaza.net/am_bin/auth_main.cgi/vouch er?
    uid=...&
    voucher_path=big long hash&

    Okay, so we know where it came in, and where it went out, and fairly precisely what time it was... So then you are in a pretty good position to extrapolate the path of the object backwards, and figure out where it came from, right? If it was moving at 400km/h, its patj would have been warped somewhat by the sun's gravitation, but that should be able to be figured in. Then you should point all your best telescopes off in the direction that it must have come from, and see what's there.

    Any good amateur rocket/astronomy folks out there? If you shot something from Antartica opposite the direction of the tip of India at 450km/sec, on October 22, 1993, 09:55:57 GMT, where would it go?

    White lists don't work because the spammers are already faking From: addresses, Received: headers, etc. so that the email looks like it comes from someone you know, just like Klez viruses do.

    Granted, few of them are doing it now, but as whitelists become prevalent, the spammers will simply maintain lists of email tuples, each tuple will have you, your mom, your uncle, and your best friend; all folks in your whitelist. Send to each address in the tuple with a From: address from the tuple, and voila, your whitelist does nothing.

    No one is saying it is okay to pirate movies; at least I haven't heard anyone say anything like that here.

    What people are pointing out is that, even in the face of the usual amount of limited piracy, the studio is making a fortune on the movie. Hence their claims that they need the DMCA in order to preserve their livelyhood are patently false.

    Similarly, their claim that every network download is a lost sale is false, as evidenced by people who have looked at the online pirated copy and are still going to see the movie at the theater.

    What you're missing is that in this forum, the context of all such discussions is that

    • the reasoning behind the DMCA, and proposed Digital Rights Management requirements on technology are flawed, and that
    • the attempts to impose and enforce those restrictions are doomed, and
    • it is actually kind of humorous when the hugely expensive attempts at such restrictions are thwarted by guys sneaking video cameras into theaters or folks using magic markers on their CD's.
    It's not that we think folks should do it, or that it's okay, but sort of like Smokey and the Bandit, it's kind of fun to watch it happen.

    This is the Purdue/ksb entombing system. Files removed by programs
    linked with "libtomb" are cached for a while (long enough to get on a
    backup tape would be best case) in case their untimely loss is noticed.

    The 3 programs are "unrm" (the user agent to get files back), "entomb"
    the system agent to cache a file, and "preend" (the system agent to
    clean the older files from the tombs.

    Included as nifty side products are "rmfile" which helps novice users
    delete files with funny names (like "-") and "untmp" which should be
    used to clean /tmp from a ".logout" type file from casual users.
