  1. Payment on Impoverish a Spammer Today · · Score: 1

    If people would read about camram and hashcash before casting aspersions about the system, they'd know that senders are not paying real money to create hashcash stamps; they're paying with cputime that would have been wasted or used for seti@home otherwise.

    I have yet to see a good objection to the following setup:

    Use camram, hashcash for initial messages and rsa/dsa signatures once a signature has been whitelisted. Anything that doesn't have a whitelisted signature or hashcash gets fed to TMDA, or another challenge-response system to validate the sender's email address.

    Plenty of people already use TMDA, and a TMDA challenge is the worst case scenario if you use the above system. The benefit is that people who are willing to pay hashcash and then sign subsequent messages don't have to worry about getting TMDA challenges from you, and get their messages delivered immediately. It also hedges against sender spoofing for those senders who have their signatures whitelisted (rather than their addresses whitelisted with TMDA).

  2. Re:The problem is... on Impoverish a Spammer Today · · Score: 4, Insightful

    It doesn't matter whether spammers hijack others' machines or not. proof-of-work stamps will still reduce the amount of spam. Without PoW stamps, a spammer with the same number of machines will be able to send an order of magnitude more spam.

    Proof of Work stamps don't magically give spammers a horde of zombie machines to spam with. They have those machines whether or not real people use stamps.

  3. Re:Slightly offtopic, but... on Blackout Was Good News, For Pollution · · Score: 1

    Not only plutonium but a variety of other isotopes can be used in breeder reactors, if the US Gov would ever lift the de facto ban on issuance of licenses to operate new nuclear reactors.

  4. Re:It's Sad. on Yet Another Degrading DVD · · Score: 1

    Worse, when studios start losing even more money, they'll blame it on pirating rather than on the much lower margin inherent in their destructo-DVDs.

  5. Re:Just remember the RAID song on Which RAID for a Personal Fileserver? · · Score: 1

    No; it's possible in linux to get the scsi controller to rescan the bus and get mdadm to accept the new drive into the array -- all without rebooting.

    Of course, if your hardware isn't hotswap (SCA scsi), the hardware may have problems and that may crash or destroy your controller, which may crash or destroy your computer, but oh well.

  6. Re:Red Mars on James Cameron's Illustrated Mars Reference Design · · Score: 1

    There's another book by Zubrin (beside The Case For Mars) called Entering Space, which deals with Mars, the rest of the solar system, and possible approaches for interstellar travel. Highly recommended for those who haven't thought about the issues involved; at least browse through them the next time you're at a bookstore or library.

  7. MS can't do this on Microsoft to Charge for FAT File System · · Score: 1

    It'll be very difficult for them to win if this is challenged. Not enforcing patent rights for 5-7 years and then having a change of heart doesn't work. If you don't enforce your patent rights through litigation in a timely manner once you're aware they're being violated, you lose those rights. MS still has the patent, they just can't enforce it anymore.

  8. Re:About the ending--**SPOILER** on 'Matrix Revolutions' Opens Today · · Score: 1

    The matrix and humans (in the movies) were not creations of an advanced AI program at MIT.

    They were both creations of a pair of rather mentally deficient, as it seems now, writers/directors.

  9. Linear fit is the wrong model on Guessing Linux 2.6.0 Release Date · · Score: 1

    That linear fit model is just plain wrong. Problem identification (and therefore problems fixed) are both non-linear in nature, for what should be obvious reasons. Three bugs, roughly three times the chance of finding one per unit time. Of course the kernel is divided into rough sections and those working on networking code are not likely to hack the vm, but this applies equally for each portion of the kernel.

    d bugs / d time = bugs
    (or if y = bugs and x = time)
    dy = y dx

    Solving this is left as an exercise for the reader.

  10. Re:In Space No One Can Hear You Scream on Sci-Fi Movies and 'Bad Science' · · Score: 1

    There's nothing wrong with silence. The current generation knows (or at least I'd guess most people watching 2001 would know) that sound doesn't travel in a vacuum, so the silence in 2001 achieves nothing except realism. It gets to the point where it approaches sensory deprivation. 2001 is a great movie, but the silence in it isn't artistic or anything, it's just an obvious necessity.

  11. Re:Is there work for a pure DHTML programmer? on JavaScript and DHTML Cookbook · · Score: 1

    Maybe because static pages load much faster than pages with server-side scripting/programming, given the same hardware. You can get millions of hits a day on static pages with minimal hardware. Start using mysql with jsp, php, or whatever, and you have to get some decent machines.

  12. recording speed on NIST Releases Study Of CD/DVD Longevity · · Score: 1

    Looks like they didn't account for different recording speeds.

    Slower recording speed = more reliable, though there are still bad cds that'll go bad quickly no matter what you do.

  13. same old lies on Questions for DoJ IP Attorneys Asked and Answered · · Score: 1

    These people peddle the same old "damage" lies.

    If someone breaks into your house and steals jewlery, it matters less that they might not have bought the jewlery if they couldn't afford it. They are simultaneously depriving the legitimate owner of its use.

    Now take the example of an architecture student pirating AutoCAD Arch. Desktop (several k$). Is there any harm? In the vast majority of cases, such people would not buy the product if they couldn't get it for free (or close to free). The legitimate owner is not deprived of either use nor profits.

    Someone ought to do a real, unbiased study of exactly those dynamics to determine more reasonable punishments for filesharing, and more reasonable thresholds for punishment. Individual piracy of more expensive software should in fact be treated as less serious because the tendency is for Companies to be (by far) the primary purchasers of that software, so the damage done by individual pirates is correspondingly less.

  14. Terrible idea. on U.S. Biometric Passports By Late 2004 · · Score: 1

    This is a terrible idea. Aside from privacy concerns, the smartcards are open to abuse and can be rendered useless. A clever person could carry around a jammer transmitting at the same frequency as the passive antenna in the card. Or some malicious person could carry a smartcard scanner around to get pictures of everyone.

  15. Great, "vim" on AOL Tests Video Instant Messaging · · Score: 0, Offtopic

    They're probably going to co-opt the term "vim." Time to break out the rabid lawyers. Or maybe not... the vim coders have no money for that. The only people who have gotten money because of vim are the kids in Uganda.

  16. most underrated... on What's Your Favorite Underappreciated Movie? · · Score: 1

    Suicide Kings is the most underrated movie I've seen, though the idiot director ended up choosing the wrong ending for the final cut. The $20k no-violence one was better, and I'm not saying that because I prefer romantic endings.

  17. Re:ProfBooty, humanities vs. academics on Grade Inflation in Higher Education · · Score: 1

  18. Re:interesting on Grade Inflation in Higher Education · · Score: 1

    Classes where a teacher hands out a set of problems and then tests on those problems are taught poorly. What good am I as a person or to society if I'm a vegetable who doesn't know the difference between Protagoras and Pythagoras because it wasn't on an exam review-sheet?

    Those teachers are creating their own Hell. I hope they're happy in it.

  19. Re:Guns on An Unbiased Analysis of Gun Crime vs. Gun Control? · · Score: 1

    No, it's not momentum/impulse. It's not energy. It's not velocity or anything else mentioned. It's the pressure exerted by the bullet that causes it to tear skin and muscle and fracture bone. If you actually quit drooling on your keyboards posting nonsense to slashdot while you recompile your kernel and download new sawfish themes, you might have the time to compute the energy and impulse of a bullet. They aren't very large. Velocity alone presents no significant danger. Gamma rays and other forms of radiation travelling at enormous speeds hit you all the time. The impulse isn't what does it: a shooter has to deal with more momentum than anything the bullet hits. The bullet bleeds off velocity (hence, momentum) during flight. What matters is the effect of that momentum/energy on such a small area of the target.

  20. Re:Center for Disease Control on An Unbiased Analysis of Gun Crime vs. Gun Control? · · Score: 1

    I apologize for the ad-hominem, but you are an idiot.

    The difference is that the 17yo gang-banger presents a threat, and the owner is legally justified in shooting him. The 10yo would not be legally justified in shooting his sister. Those "children killed by guns" statistics are used by the anti-gun crowd to show how dangerous guns are to innocent victims. The 17yo is not an "innocent victim."

  21. dry ice on Fun with Fog Generators · · Score: 5, Informative

    The problem with dry ice is that it's dangerous (CO2 asphyxiation) in closed areas, and outdoors nothing will work terribly well.

  22. Re:You missed: on California Bans Mobile Phone Spam · · Score: 1

    No, that's not covered. States don't have some magical jurisdiction over events just because they involve someone who has a residence in the State. Only sovereigns (like the U.S.) have jurisdiction over citizens when they're outside the country.

  23. who cares? on AMD Opteron to support Palladium · · Score: 1

    GCC is open source, and even if someone convinced developers to add palladium code generation to it, someone else would come up with a patch to remove it.

    Very sad. He did leave plenty of work for us to remember him by, though.
