  1. Re:SIGSEGV on New (More) Annoying Microsoft Worm Hits Net · · Score: 2
    The problem is apparent on Apache's below 1.3.12 and they appear to segfault when they obtain any query string containing a %2f.

    Check out:

    http://bugs.apache.org/index.cgi/full/543.

    One of the requests made by the worm is:

    "GET /scripts/..%c0%2f../winnt/system32/cmd.exe?/c+dir HTTP/1.0" 404 309 "-" "-"

    You will probably find that this is not in your logs and that a segfault appears in it's place.

    We failed to find any workaround but the server load is so low that we dont deem it worth the hassle of upgrading to a newer apache.

  2. Re:I wouldn't go with integrated systemboards on Motherboards With More Slots Sought · · Score: 2

    I dont really see what the problem with integrated sound is. Comparatively few people ever actually record things using their soundcard and anyone that gives a damn about quality will surely be using a digital interconnect between their soundcard and amplifier.

    I've heard a cheap ($15) soundcard connected to a dts speaker system and as you would expect - it sounds fantastic.

    Obviously if you insist on analogue then it's a bind but moving the DAC outside of the computer case is the only way to get half decent quality.

  4. Only 30m long! on Superconducting Power Cables in Denmark · · Score: 4

    For you americans thats a little over 110ft. I could be misunderstanding this (and i certainly dont speak danish) but I thought the largest gain would be through using this is long distance transmission lines.

    As i recall the loss in a cable is P=(v^2)/R so the lower the resistance the lower the loss in the line. As the resistance of a wire is proportional to it's length P=(v^2)/(al) so the greatest losses are on long lines.

    None the less this is still a fantastic acheivement and will hopefully pave the way to more widespread use.

  5. Seems like a stupid idea on "For Use on Free Operating Systems, Only!" · · Score: 3

    Apache is a nice example here. It runs fine on Windows and I suspect quite a few NT admins have chosen to run apache over IIS for price/performance issues.

    Hopefully these sys admins will see that open source can provide a very high quality solution and perhaps their next server will be Linux.

    As open source projects get more mature I really think that more work should be put into porting them to windows and macos. Having a user using OpenOffice instead of M$Office is excellent and puts them one step closer to adopting a free OS.

  6. Try doing a little research on Reporting Functionality for Web Applications? · · Score: 2

    There are lots of perfectly good windows reporting tools and if you dont want to have to do any work yourself - GO BUY ONE!

    I'm as much in favour of linux (and uk spelling) as the next guy but to be fair windows has better tools for this sort of thing.

    If you want to go down the linux root then I suggest using perl or php to create a pdf file which the client could then print. It'll require a fair chunk of effort on ur part but the final solution will be infinitely more controllable than it would be on a drag and drop windows system.

  7. Since when was TV a basic human need on A Different Kind Of Digital Divide · · Score: 4

    Perhaps I misread the UN Declaration of Human rights, but the last I heard tv was a luxury.

    There has been a lot of likening of PBS to BBC. I live in the UK and I pay £104 ($160) a year for the luxury of BBC1 and BBC2. That is more than I spend on my whole (albiet limited) cable TV package in a year. It's also more per channel than any of the movie channels I have on digital satelite.

    For those of you in the USA, we actually have to pay for a tv license here (or they give u big fines apparently). And for that we get just TWO television channels (completely commercial free i might add) that manage to have more quality programming than the 300 or so i have on satelite.

    You cant really have things both ways. Personally I prefer the way of having everyone pay a blanket fee to produce quality programs, but in the US you chose (surprise surprise) the more commercial route.

    Why not custom design decent games designed for the intricacies of these interfaces.

    Somehow I though atari games were meant for big screens and normal keyboards... not what i want to see on my nokia.

    Why not redesign them, do it efficiently and add multiplayer capabilities that would make it a lot more fun.

  13. Seems a bit flawed to me on Professor Describes Unbreakable Cryptosystem? · · Score: 1

    First of all if I happen to know that communication was taking place at a certain time then I can quite feasibly capture a few minutes of the one-time-pad and this dramatically narrows the search field.

    Secondly there is the obvious problem of generating a random and infinite one time pad, which is one hell of a problem.

    Thirdly this assumes that you have tightly sychnorized communication - it's not a lot of use for emailing my encrypted 'thoughts' to my girlfriend.

    Fourthly there's nothing new about one time pads - they have been in common use for the last 40 years and I dont really see how this method evades the problem of key distribution (except for the fact that it's transformed into "key sychronisation").

    Fifthly if two pairs of parties start communicating at the same instant - wont they be using the same keys.

    Sixthly he bases his hypothesis that computers have a limited amount of storage and power. Firstly consider 10 million bytes a second - i could quite happily store an hours worth of keys on my computer. As for computing power, we are reassured that quantum computing will be just around the corner and where will this fit in if computers can run an infinite number of simultaneous calculations...? It'll be dead just like rsa will be

  14. ALPINE as a DDOS amplifier network on New Peer-to-Peer Designs · · Score: 2

    From what I can tell, if i root a few boxes on nice fast t3 lines then i can send out a query to all hosts on the alpine network searching for all songs with a "3" in the filename. That should return every mp3 on the planet :)

    Now since the query is udp based I can spoof the return address to www.ebay.com. Ooops :) For every tiny search packet I send out, hundreds of results get fired at ebay from a whole pile of hosts that would normally use their site for legitimate reasons.

    Also you cant throttle your bandwidht on alpine. Certainly you can send out less searches but if you have 100,000 users online then there will be about 5000 searches a minute, and every 33.6 user will have to download all thoses queries.

    Mathematically it doens't work out quite as badly as gnutella, but it still sucks :)

  15. Paying for downloads is one thing.. but from where on Napster Introduces Subscription Charge · · Score: 2

    Right now it's clear that the bulk of big faster napster servers are run by Students. If my university weren't so tight fisted then i'd run one (but the 28.8 connection with per minute charges that they give me free doesn't quite hack it).

    However I wouldn't run a server so that some corporation can get rich out of it.

    Why should users pay napster and the record company so they can download a song from me!?

    I wouldn't share on napster if it made napster inc rich.

    Napster will soon find that for their business model to succeed they'll have to pay the servers - sadly that's unethical :)

  16. Re:A Couple things about the standard on French Hackers Break SDMI · · Score: 2

    I cant see any reason why having a key longer than the message would hinder cracking the encryption.

    Quite simply you have to brute-force and try all possible keys (admittedly if u dont know the length of the key then it's trickier)

    Quantum Cryptography does seem to be the solution but it's not exactly in a real usable form just now.

  20. Re:Is any encryption safe? on Money For Nothin' From The SDMI Hacking Contest · · Score: 1

    Any high school student who's done a basic course in number theory can break RSA. The simplicity is part of the beauty of it.

    RSA and SDMI are not comparable though.

    SDMI is not an encryption scheme in the normal sense since every user with an sdmi enabled winamp can decrypt it. It is however a watermarking scheme - something which is immensly difficult to acheive.

    What SDMI is trying to achieve is roughly equivilent to trying to hide the message "BILL SUCKS DICKS" inside this posting - but so no-one could see or remove it - complex stuff.

    Ultimately Intel obviously dont want Windoze ported to anything else since that's a threat to their dominance.

    And Microsoft probably dont want to develop windows concurrently on 10 different architectures (think of the cost!) and so it suits them fine to stick with x86.

    AMD however have shaken things up a little since their sledgehammer will keep MS on the x86 platform and leave intel somewhere else...

  24. Re:Who cares? on Pentium 4 Delayed · · Score: 3

    Traditionally AMD's market has been the entry level pc one, and they've never had such things to worry about.

    Right now thier main worry is keeping production up to speed to keep intel out of the top slot.

    However most current users of SMP are high end server manufacturers, and most enterprises prefer to use the tried and tested intel xeons in their systems.

    It would have been foolish of amd to focus their efforts on smp when their chip didn't have the respect it does now.

    The good thing is that the EV6 Bus lends itself a lot better to multiprocessoring than intel's architecture. We may yet see a 32 cpu AMD system.... sweet :)

    Intel on the other hand just cant do that until they get their itanium chips rolled out (late 98 I seem to recall :). But AMD on the other hand have the sledgehammer ready to strike back at the itanium.

    The future looks bright for amd so long as they escape any major cockups.

  25. Re:Who cares? on Pentium 4 Delayed · · Score: 4

    Well this isn't really true.

    True most people will only have one active window at a time... you cant have any more on windows. But look at the amount of crap running in the background. My flatmates twin celeron feels VERY responsive because even when one app is hogging a cpu it's got one free to service all the routine crap.

    Word itself has been threaded for donkeys years, and any multithreaded app should automatically become an SMP version when there is more than one cpu. Also given the state of windows programming i'm starting to find the strong benifits in multithreading shit just from a coding point of view.... debugging is a whole other matter though.

    Additionally as SMP becomes more accepted we will soon see more and more supporting it, since most software developers out there have some deep resentment cauasing them to want to strike down intel and micro$oft.

    The other point is that word itself SHOULD NOT be able to occupy a whole p3 700 cpu for any length of time anyway... it's just an abuse of resources and we all know that microsoft wouldn't stand for it.

    Bear in mind that AMD hope to have dual cpu duron and athalon mobos out in the next 4 months, and have 4 and 8 way ath boards out by the end of next year.

    That should shake things up a bit, particualrly if you could run 8 $100 duron 1.5ghz (sounds about right for the end of next year) for little more than intels latest and greatest 2.6ghz p4.
