  1. Re:Ummm... on Pulse Detonation Engines: The Future of Aviation · · Score: 2, Informative
    Octane ratings are a little more complicated than that. Leaving aside the fact that there are two ways to measure octane ratings, the idea is to get as many branched molecules such as iso-octane (2,2,4-trimethylpentane) into the fuel as possible, as these burn more slowly than straight-chain molecules such as heptane (which explodes if you look at it too hard).

    In the UK this is done by catalytic reforming to produce benzene and other ring-shaped molecules. This certainly gets the octane rating up to 95 or 97 ("premium" and "super" unleaded respectively) but, from a health point of view, may actually be more harmful than a bit of lead bromide in the exhaust. The alleged link between lead in exhaust fumes and childhood development was always hard to prove, although lead itself is undeniably toxic in the wrong forms. Benzene is carcinogenic in any quantity. We may have swapped one problem for another.

    As an aside, a friend of mine worked at a factory where they had a lot of bulk benzene available - all the managers were running their cars on a 50/50 mix of benzene and unleaded petrol. Naughty.

  2. Another link here on Los Alamos to Use AMD's Opteron in Linux Clusters · · Score: 1, Insightful

    At The Register. Sad that all this power is being used to simulate nuclear weapons (and presumably speed up GWB's adoption of battlefield mini-nukes), rather than its proper purpose of getting more fps at UT2003.

  3. Foreskins on Cloning Yields Human-Rabbit Hybrid Embryo · · Score: 4, Funny

    RTFA and you'll find the cells used for the DNA were a mix of rabbit skin and human foreskin. Imagine explaining that when your long-eared, buck-toothed teenager asks "Daddy, where do babies come from?"

  4. Is anyone pretending to be Slashdot? on Friendster Fights Fakesters · · Score: 5, Funny

    Geek discussion site seeks similar for karma wh0ring and meaningful flaming. Interests include Linux, not paying for stuff, and sticking one over on The Man. Dislikes include Microsoft, the RIAA and SCO. Please include a recent screenshot in your reply. All respondents must be compatible with Mozilla 1.4.

  5. Re:Already in the water? on Global Warming To Leave North Pole Ice-Free · · Score: 1
    This isn't strictly relevant to the North Pole, where there are no glaciers (because there's no land), but it's a good point for places like Scandinavia.

    The floating ice won't make any difference to sea levels if it melts, because the part above the water is just the extra volume gained by the ice as it freezes.

  6. Oh, come on on EFF Coordinates Fight Against DirecTV · · Score: 0, Interesting
    You play with fire, you get burned. You could argue that it's actually worse than software "piracy" because most of these people COULD afford the subscriptions if they wanted to, and are therefore depriving the producers of income (unlike, maybe, potential users of Photoshop at $600 a pop who could never afford it anyway).

    In this case I can't buy the "substantial non-infringing use" argument, as having dabbled in satellite technology for a while, I know how huge the market is for pirate cards. It was one of the factors in the collapse of ITV Digital in the UK, as half the population of Scotland - where for some reason, this is especially rife - were using bent cards.

    There also used to be a huge trade in D2MAC cards and PC-connected EEPROM programmers so people in the UK could get free Swedish pr0n and Premiership soccer games on Norwegian TV.

  7. Effect on Internet traffic on Win32 Blaster Worm is on the Rise · · Score: 1

    Absolutely zilch so far. I'm sure other major worms have shown up as a big spike. Move away folks, there's nothing to see.

  8. README.SCO on FSF, GCC, and SCO Compiler Support · · Score: -1, Offtopic

    Apparently the .sco file extension is used for CSound musical scores. The inclusion of this file is going to disappoint many users who thought gcc had gone all multimedia ;-)

  9. Isn't it ironic on Cheap Wireless for Accessories · · Score: 2, Funny

    Even a two-dollar protocol like this works at several hundred Kbps, when I have a network of computers at home, with enough MIPS to simulate El Nino, connected to the outside world through a 64k bit of electrical string. When it's dialled up. But that's telcos for you!

  10. Altogether now... on Better Power Supply Roundup · · Score: 3, Insightful
    Who, among home users, just buys the cheapest PSU they can find with enough power? Or is it just me? Some good reasons:
    • On my machine the CPU fan drowns out the noise of any PSU
    • With the way things are going, I'll need to buy a different PSU next time (ATX may die out, or everything will need 450W)
    • You can't see them, so they're not sexy
    • They make no difference to performance
    • Most of them last a reasonable time. I've been running different PCs for an aggregate of 11 years, and I've had one dead PSU in that time, costing 30UKP to swap out.

    You could argue that people running servers should care even less, because they normally have redundant PSUs.

  11. Re:great on Comparison of Bayesian POP3 Spam Filters · · Score: 2, Informative

    Yahoo uses captchas to prevent scripted sign-ups, so if you get anything from a Yahoo mail account, there was once a human (OK, a subhuman) at the other end.

  12. Re:Mozilla - filters on client not server on Comparison of Bayesian POP3 Spam Filters · · Score: 1

    You use the TOP command on a POP3 server to get just the first part of the message. That should be enough for a good Bayesian filter. Fire up Telnet and try talking directly to the server - it's quite enlightening (and essential for when some "friend" sends you a 15MB movie file and you're on dial-up). Some instructions here.

  13. Mozilla - filters on client not server on Comparison of Bayesian POP3 Spam Filters · · Score: 3, Interesting

    Moz's Bayesian filtering works well, but its Achilles heel is that it doesn't work on the POP3 server, so you still have to download everything. As POP3 allows the header and the first part of the message body to be read without downloading it, surely there could be an option - once Moz has been trained and you're fairly sure the false positive rate is negligible - for filters to operate on the server and delete spam from there?

  14. Re:great on Comparison of Bayesian POP3 Spam Filters · · Score: 1, Informative
    Well, I rarely find anything watchable on BBC1 or BBC2 these days (too many soaps, trashy sitcoms and repeats), and the licence fee, while it's cheap compared to Murdoch's Sky subscription, is a tax on watching TV, not an optional payment. Even if you only watch satellite or cable channels you have to pay the BBC.

    You used to get a free satellite viewing card for your licence fee giving access to all the "terrestrial" public channels on satellite, which was great if you had a spare decoder and crappy terrestrial reception like where I live. To save a few quid, the BBC no longer fund these cards and have gone unencrypted, which means I've lost the other terrestrial channels upstairs. Thanks guys.

    Half the time they just run out of the daily bandwidth allocated to them by their ISP, especially if they're on a free web host like Geocities. That's not a technical problem, it's a financial one.

    There were at least three versions of Windows 95, the last (OSR2) of which was very similar to Windows 98. Do we know which version was used, as presumably the later and more functional releases were larger?

  21. w00t - another way to get RSI on New Microsoft Mouse Scrolls Both Ways · · Score: 1

    I do hope they've tested this sufficiently. My right arm was finished with mice 3 years ago, and (after teaching myself to become ambimoustrous like GLS) the left one is now developing twinges.

    I've just rebuilt an old P166 and overclocked it to 200MHz. No fan, but not much heat either, even in the current record temperatures over here in England. It ran a 100% burn-in test for an hour without crashing. It's a big heatsink and I used Arctic Silver II (mixed reviews, but works for me) between the CPU and the sink.

  24. TV talent competitions on The Effect of Pirated CDs · · Score: 1
    They're killing music by destroying any remaining vestiges of creativity. These guys (and girls) are cabaret singers, nothing more, nothing less. The lyrics and music are by someone else (manufactured to fit whatever they think will sell, not from any real emotions) and they just want a pretty face for all the pre-teens to slobber over. Can't sing? Our computer can fix that.

    It almost makes you want to listen to Marilyn Manson. Almost.

  25. Odd quote from website on MPAA Opens Anti-filesharing Website · · Score: 2, Interesting
    Most of the time, the movies available for download on the Internet are obtained when someone sneaks a camcorder into a theatre and illegally records the movie up on the screen. The sound isn't right, the picture isn't in focus, people are walking in front of the camera, and scenes are missing.

    Why would scenes be missing? Does the camcorder guy take a wizz every half hour?
