  1. Re:just use the edge of the disk on Wear Leveling, RAID Can Wipe Out SSD Advantage · · Score: 1

    Yes, disks are cheap

    The power to run and cool them, and the space to hold them on your data center floor, are not.

  2. Hosting Matters on Things To Look For In a Web Hosting Company? · · Score: 1

    ...so I use Hosting Matters. Been using them for years, they're cheap, provide MySQL and cpanel access, sftp, and ssh (if you ask). Their rates are reasonable, and -- bonus -- every time I've filed a help ticket, I've gotten a response in hours*, and it's always been knowledgeable.

    *Once it took 12 hours (essentially overnight) and the support rep apologized for taking so long.

  3. Re:1. Upload to Wikileaks with Xerobank 2. Link to on Hosting a Highly Inflammatory Document? · · Score: 4, Informative

    Depending on how important/inflammable this document is, I might look into buying a cheap 20GB laptop hard drive, installing ubuntu, going to a star bucks, doing the above and then "disposing" of the drive and all media so that there are no questions.

    For this to work you would also have to change your wireless interface's Ethernet MAC (hardware) address. By default this is a vendor-specific code that is probably unique enough that it could be used to link you to the upload. This would require that (a) the coffee shop kept some kind of long-term logging on their wireless device, (b) the authorities were able to trace the upload to the coffee shop, and (c) the police had some kind of suspicion of you already. All are improbable, but none are impossible.

    Most wireless cards will let you change the hardware address. I'll leave instructions for how to do that to the enterprising googler.

    The alternative is to use a cheap throwaway laptop with wireless, or a disposable wireless ethernet card.

    (Yes, it's paranoid, but so is the original question.)

  5. Re:3 to 3000 percent? on MS Researchers Call Moving Server Storage To SSDs a Bad Idea · · Score: 2, Informative

    Enterprise tape has a proven 20-year shelf life, no HDD does.

    That may be, but I've lost track of the number of times (as a storage engineer) that I've seen tape backups go bad. Even "enterprise-quality" tapes. I think the claims don't match the reality.

    Hard drives die too, but in the case of drive storage (1) it's a lot easier to verify your backups on a periodic basis, like every month; and (2) you can suffer a failure or two (depending on your RAID setup -- most people wouldn't run anything more than RAID-5 for backups) and react accordingly to preserve the data in full.

    Of course, if you're really serious about your backups, you back up to disk and THEN offload to tapes and keep those offsite.

  6. Re:without any humans ever having been involved on Using Speed Cameras To Send Tickets To Your Enemies · · Score: 5, Informative

    The legislators have thought of that. It's an infraction, rather than a misdemeanor, so it's an administrative fine -- it goes on your driving record, but not your criminal record.

    Because it's a criminal charge, you aren't given the right to face your accuser.

    It's a perversion of justice for the profit of the state, but right now the judges let it pass constitutional muster.

  7. The console will evolve the RTS on New Details On Halo Wars · · Score: 2, Interesting

    Or at least, I hope it will.

    I've been playing RTS's off and on since C&C and Warcraft (the original), and I've always had a love/hate relationship with them. I love the strategy and tactics of the genre, but the whole concept of "micro" and continuously abysmal unit AI just infuriates me.

    For instance, in the dominant RTS paradigm, if I have a group of units standing in a group in my base, I get two choices: leave them in "free acting" mode, where if they're attacked by some plinker my opponent sends, they'll rush headlong into whatever danger lurks outside the base, outside the range of my fortifications; or they can stand there in "hold" mode, and get picked off impassively by ranged enemy units as their mates stand around watching them bleed.

    Why can't I tell them to automatically scatter and get behind fortifications to fight back? Or maybe retreat to draw the enemy into range of my big, immobile guns/cannons/wizards/what have you?

    Since micro is so much harder on a console than a PC, my hope is that console RTS developers will address some of these issues, to reduce the frustration of unit management.

  8. Re:Interesting on Aquaduct Bike Purifies Water As You Pedal · · Score: 3, Informative

    Some of the areas of the world with the worst water quality are very high-humidity, where you may sweat even if you're riding at 20 mph.

    And as far as "not pushing yourself hard enough," in most of the world, a bicycle is primarily transportation, not exercise.

  9. Ignoring the warranty on Microsoft Innovates Tent Data Centers · · Score: 1

    Unconventional data centers that don't provide adequate services will start costing these companies in other ways: canceled warranties. Warranty clauses always require that the company purchasing the equipment ensure an operating area within device specifications for humidity, temperature, shock, power, etc. The vendor can void the warranty if you go outside these bounds.

    Currently this is not much enforced, except in egregious cases. I've even seen a vendor replace servers that fell out of a truck (literally) out of "good will," because it was a rare case. But if a company makes a stated goal of reducing operating costs by passing them onto the vendor via the warranty, expect these clauses to be given far more attention.

    Big companies like Google and Microsoft are cash cows for enterprise vendors, and may be able to get away with it, but small- and mid-sized companies will not find success in these data centers, should they ever become a reality. Remember, an increase in a failure rate from 1% to 2% is doubling the warranty replacement costs!

  10. Just make a different user on Securing Your Notebook Against US Customs · · Score: 1

    On either Windows or Mac OS X, encrypt your home folder (or whatever data you don't want seen). Then make a different user with enough customization to be believable (different background, etc. -- bonus points if it's a badly pixellated picture of your kids or girlfriend or something), and if the customs agent makes you log in, use the decoy user instead. That way your data is never decrypted and you never type a password they could use to access it.

    If you're really worried, make the real user a different name than yours, so you can claim it's the login of somebody else who might plausibly use your computer, and that you don't know the password.

  11. Re:Etymology on 'w00t' Named 2007 Word of the Year · · Score: 1

    I concur with this. I was in #doom in EFnet around 1994 when people started saying "whoomp" all the time because of that song. At the same time, there were references to "r00ting" boxes. "Whoomp" became "woo" became "w00" became "w00t".

    I'm not claiming it happened solely in this channel, but that was definitely when the word was getting off the ground.

    This "We own the other team" nonsense is definitely a backronym. When the word first appeared, you couldn't even play team deathmatch in online games.

  12. Serious authority on Wolfram's 2,3 Turing Machine Not Universal · · Score: 3, Informative

    I don't understand the math behind this argument and counter-argument, but Vaughan Pratt is a CS legend and one of the early cofounders of Sun, to boot. You also might have run across his name in a cite or two in The Art of Computer Programming series by Donald Knuth. And if you don't care who Knuth is, then you probably don't care about this post at all.

    I knew Pratt's daughter in college -- nice woman. Wrote her term papers in LaTeX, on a Linux workstation, in 1996 :P

    Does Sweden have a system that allows the public to look up political contributions? If so, look at who's given money to this prosecutor or the party of those who appointed him. I can predict what you'll find.

    Speakeasy used to be such an ISP. With their recent acquisition by Best Buy, I'd no longer gamble that way. But there are other ISPs who will be just as tolerant.

    You just won't get them for $30/month.

  16. Won't work with BitTorrent on DSL Gateways to Fight Piracy by Marking Video · · Score: 1, Offtopic

    The .torrent file you use to start downloading a BitTorrent file has checksums for all chunks of the file. If a chunk is altered in transit, the BT clients receiving it will detect this and discard it (and intelligent trackers will eventually kick you out of the P2P cloud).

    The only possible application for this is tagging files transferred as unencrypted streams, such as HTTP or FTP.

    Yes, the building itself does curve with the surface. I have been in it, and if you kneel down on one end you can see the earth's curve looking toward the other end (when there isn't something in the aisle on either side of the cyclotrons).

    Liquid gasoline only explodes in Hollywood. You can drop a match into it and the match will go out.

    Gasoline fumes, on the other hand, can definitely explode. While it's a fine distinction, it's an important one.

    In fact, the technological advance which finally permitted combustion engines was figuring out how to vaporize gasoline so that it would burn.

    Please cite a reference, since Google doesn't back you up.
    I'm not sure about the GP's story, but here are two web references:

    National Institute of Health:

    Epidemiological studies attempting to link AD with exposures in drinking water have been inconclusive and contradictory. Thus, the significance of increased aluminum intake with regard to onset of AD has not been determined.

    Alzheimer's Society (UK):

    The overwhelming medical and scientific opinion is that the findings outlined above do not convincingly demonstrate a causal relationship between aluminium and Alzheimer's disease, and that no useful medical or public health recommendations can be made, at least at present.

    It appears the consensus from reputable sites is that we don't know, and there's no consistent correlation that's shown up in studies so far.

  23. Easy solution for Netscape & Mozilla on Dealing with the Unix Copy and Paste Paradigm? · · Score: 1

    If you copy a link (Unix-style, by highlighting) and then paste it into the body of the browser window, (i.e. where the web page is actually displayed) by middle-clicking, Mozilla will actually go to the site as if you'd typed the URL into the location bar. This has worked for as long as I can remember, and I've been using Netscape since 1.1.

    That way you don't have to remember to delete the URL in the location bar before highlighting the URL you want to paste.

    It's actually kind of annoying if you use middle-click to open a link in a new tab, and you miss, AND you happen to have a URL in your copy buffer. But otherwise, very handy.

    Interesting. Those passwords are mostly made up from the home row on a qwerty keyboard. Obviously somebody just banged them in (literally) instead of using any kind of random character generator.

    I wonder if anybody has written a password cracker that focuses on the "asdfghjkl;" row. That's certainly a much, much more limited set of combinations than the full keyboard, especially without capitals!
