  1. Re:Saved! on Next Generation Stun Guns? · · Score: 1

    Tasers need darts.

    I doubt your clothing would be conductive enough if the voltages etc are similar to tasers. Of course if the beam is continously pulsed, they could sweep it about to ensure they hit your skin.

    As for the claim that the laser beam won't cause damage to eyes, OK so let's assume it won't, but how about the 28W 50kV that follows the laser beam?

    Or make like a christmas turkey and wear lots of aluminum foil ;). If you're lucky you might even deflect the beam back to them.

    If you're really unlucky you might deflect the beam to the nearest highly charged thundercloud, or an unshielded High Voltage power transmission line...

  3. Re:$2.00 Beam deflection on Next Generation Stun Guns? · · Score: 1

    I wonder if someone would add this to the manual:

    Do NOT ever fire laser skywards especially at thunderclouds... Or fire it at anything that would near perfectly reflect the beams skywards...

    I've mentioned it before, but I'll mention it again coz it's kinda relevant - the 747 plane laser can be quite useful for assassination. Do it right and it'll look like the target was hit by a lightning bolt. With associated thunder clap (superheated air) etc.

  4. Tangling on Baby Steps Toward Quantum Computers · · Score: 1

    What if you consider the entire universe as whole, and that we're all entangled anyway, and "decoherence" is just one sort of entanglement? I mean what really is decoherence and coherence when most stuff was probably tangled from the beginning?

    What if they sent one half of pairs of entangled particles on Ship A at near light speed, leaving the corresponding partners on earth. Then you send another bunch on Ship B, 100 years later to meet up with Ship A as it returns half way and you decohere stuff.

    Would you be able to figure out when the ships meet by trying to get the different ship's earth bound particles to form interference patterns with each other, pair by pair (in agreed order - a.g. A1 with B1 at Time1, A2 with B2 at Time2).

    Hmm, what if part of _you_ were the entangled thing.

    The main thing is how often do you have to do all that?

    How many linux kernel security probs so far this year? Too many.

    With Linux's quality as it is, Windows doesn't really look so bad. So far most of the bugs have been IE related, and given my Win2K config, I'm not vulnerable to most of them (on my PCs, scripts etc can't run in the My Computer zone, scripts can only run in sites listed in a custom zone - unlikely for attackers to add sites to my custom zone).

    FreeBSD 4.9 had two kernel level probs so far this year (shmat vuln and tcp DoS). Too many as well, but still fewer than Linux.

    So far this year, OpenBSD has had a shmat bug too, an IPv6 MTU DoS and a procfs problem. OpenBSD is having some probs with some IPSEC stuff tho the last I checked, but that's not a kernel prob.

  8. Re:RAID 0,1,5 on Chipset Serial ATA RAID Performance Exposed · · Score: 1

    But raid5 is terribly slow when it comes to writing - sometimes slower than a single drive. Bad case scenario = writing lots of small files.

    RAID 10 is unlikely to get slower than a single drive.

    If you're have an external storage array, then sure go striped RAID5 or something, coz the last I checked SAN connections aren't that fast - 1Gbps (125MB/sec) or 2Gbps (250MB/sec). Could easily hit the limits of 1Gbps with RAID10.

  9. Re:Well lets see here on Chipset Serial ATA RAID Performance Exposed · · Score: 1

    Use RAID1 and a nonbraindead RAID controller for read speed- can read from either drive as convenient - you are not forced to fetch data from a particular drive - coz the same data is on both drives.

    I figure he got this wrong:
    Intel ICH5 RAID 0: 55 MBytes/sec
    Intel ICH5 RAID 1: 120 MBytes/sec

    And he meant to say:
    Intel ICH5 RAID 1: 55 MBytes/sec
    Intel ICH5 RAID 0: 120 MBytes/sec

    Otherwise it says other things about the Intel controller.

    I've been looking for RAID1 solutions that are genuinely hardware (e.g. work with *BSD and Linux), and that are able to do read interleaving for sequential reads (and other algos for random and semi-random reads - nearest head etc).

  11. Re:Best Upgrade on Chipset Serial ATA RAID Performance Exposed · · Score: 1

    Yeah, but not many RAID controllers appear to do that (what do you call it? read interleaving?). I suspect the expensive 3ware stuff do, but I believe most of the rest don't.

    If you can show me a list of RAID controllers that do that read interleaving sort of thing, I'd be interested. Coz I know it's technically possible (and shouldn't be that difficult[1]), but somehow it's not common.

    [1] Heck even a naive algorithm like every other read going to the other drive should still be better than single drive. Just a bit of thinking/researching will provide far better algos.

  12. Re:Best Upgrade on Chipset Serial ATA RAID Performance Exposed · · Score: 1

    Funny thing is I see about the same number of complaints about RAID controllers failing as I do about high end SCSI disks failing.

    But maybe the SCSI disks are expected to fail so people don't complain so much.

    Still, I don't see why I should see that many complaints about RAID controllers failing in the first place - they're pretty simple things compared to many other devices. Esp when one of the common reasons to use a RAID controller is for higher availability! Doh.

  14. Re:Why not quad core? on AMD Going Dual-Core In 2005 · · Score: 1

    Coz AMD already spec'ed for dual cores at the start.

    Look at the thermal design stuff where AMD said 80+ Watts for their entire range of chips no matter what the frequency. Some silly people thought it meant the Opterons/Athlon64s ran hot and said dumb things.

    What AMD actually was doing was making sure that as many PC/Server makers as possible would make designs that worked with 80+W chips.

    With current chips dissipating from 30W-55W, "drop in" dual cores are definitely feasible. Make a 2 x 40W dual core chip, and it'll work.

    If AMD's move to the next manufacturing process actually creates cooler chips that'll even be better. In Intel's case the move doesn't seem to have helped - see the Prescott. However it could be that all that heat is because Intel is trying to avoid using some stuff that it doesn't have patents for (e.g. IBM's stuff).

    AMD has a deal with IBM for Opterons. Will be interesting to see how far that goes.

    Hope AMD stays alive - so far they're making things quite interesting and in good ways too. Whereas Intel is doing stuff like Itanium, Prescott and BTX.

  15. Get a driving instructor to do it. on Realistic Driving Simulator Games? · · Score: 2, Insightful

    Over here the typical driving instructor's car has brake pedals on the instructors side, so the instructor can slam on the brakes if the student does something stupid/dangerous. A handbrake just doesn't cut it, if your kid really sucks.

    And if your kid adds some "unusual wear and tear" on the car it isn't to your car.

    That's what my parents did - they sent me for about double the typical hours of instruction - just to gain real road experience - even though my driving instructor was a bit unconventional - for the later part of my driving lessons, much of the time was spent driving my instructor from place to place as he did his errands (buy groceries, send them to his mom, miles away) - even driving in rush hour traffic. It kinda worked out - I passed first try.

    Go look at the plane flying scene - after you learn the basics (and are in less danger of killing yourself or others), it's the hours of flying time that count. Of course you could go for the advanced driving stuff - that's useful too.

    Most people where I am try to go for the minimum number of lessons to save money, but what happens is they can pass the tests, but they can _barely_ drive safely.

    Heck I know a few kids who've crashed their family cars soon after passing their driving tests. And I wouldn't trust their driving. They treat it like it's a _game_.

    So I'm not sure if a "game" would be good.

    After the instructor is done with them, you can teach them how to be safer.

    Try stuff like distracting them whilst they are driving (in safe+controlled conditions)- drop something on the mat, if they should NOT get distracted overly by that. I mean something dropping on the passenger side mat is unlikely to be a bomb or anything dangerous.

    If you're travelling at 100km/h, or 80km/h in heavy traffic, if you spend one or two seconds looking at the floor, it could be your last few seconds of your life as a fully abled individual.

    AFAIK the losing party in the recent Indian election did not question the results.

    AFAIK the results were pretty much accepted by most of the 1 billion people. So India could indeed be considered the world's largest democracy.
