  1. Public webcams on Google Exposes Web Surveillance Cams · · Score: 1

    I'm surprised that it's gotten this far without somebody mentioning science fiction.

    H. Beam Piper's stories included a standard trope, in which there were many publicly available cameras in various places. "Telescreen" users used their output instead of wallpaper images, and Pappy Jack used surveillance images of a forest fire to scare Little Fuzzy.

    Hey, slashdotters! Who wants to step up and provide that service?

  2. Chopping DC on Build A Nixie Tube Clock · · Score: 1

    This is a bit of technojargon. As far as I know, it originated with op-amp developers. Alsee has it right, but perhaps you'd like a little more development of the idea.

    "Chopping" refers to turning the DC on and off so as to generate an alternating current that can be used in transformers. Modern power supplies do it the way described because higher frequencies allow smaller and lighter transformers for the same power level. Older-style, mains-frequency transformers are big and heavy, and aren't efficient -- largely because the low frequency means they need iron, and the iron has hysteresis and other losses.

    Really small, cheap, low-power power supplies don't even use transformers any more. They use capacitors and diodes in voltage-doubler circuits.

  3. Re:It's a Ballard fuel cell on Fuel-Cell Backup Power Under Your Desk · · Score: 1

    The problem Ballard (and almost everyone else) is having is the catalyst.

    Fuel cells require platinum as a catalyst to keep the reaction temperature down to where the materials can survive. I've been following the tech desultorily for quite a while; several people have tried palladium or rhenium, with generally bad results, and anyway rhenium is harder to get than platinum, and all the palladium is going into catalytic reactors for cars.

    The problem is that platinum is hard to work with; a very high melting point, low vapor pressure, and not very "sticky". So all the wonderful vacuum-deposition tricks that are useful with aluminum and other metals fall down.

    Which leaves foil and pressure, which is what they mostly use. The trouble with that is that it uses a _lot_ of platinum -- the foil has to be thick enough to handle, which is way overkill for the amount needed for the fuel cell. The number I heard was that a 1000KW fuel cell -- about right for a high-powered car, or a medium-small truck -- would need $30,000 worth of platinum. Ouch.

    So put your thinking caps on. If you can work out a reliable, relatively cheap way to do vacuum deposition of platinum that can be process controlled to give an even coat at the one-molecule-thick level, load the gear on your truck and take it to Vancouver. The folks at Ballard will be glad to see you.

  5. Due Diligence on Negligence and Open Source · · Score: 2

    Mr. Perens has (as usual) an apt comment. Disclaimers:
    1) IANAL
    2) I am not directly associated with Open Source Software.

    The concept of due diligence is hyper important. In fact, a finding of negligence is essentially a finding that due diligence was not performed.

    What I have seen of Open Source indicates that the people who work on it are extremely "diligent" where bugs of all kinds, not just security bugs, are concerned. When one is reported, generally someone gets after it right away, to (1) confirm it's there (2) figure out what a fix should be and (3) fix it. This is an historical pattern, I believe, and could be substantiated by lots of testimony.

    Note that the Law doesn't require that the bugs actually be fixed, or that the fix be better than the bug was. Due diligence simply means that all reasonable methods were used to conclude what the problem was and how it might be fixed, and to fix it if it seemed warranted.

    Note that in the Pinto and GM Truck cases mentioned above, due diligence broke down -- the companies involved concluded that the problem existed, but that it wasn't economically justifiable to fix it, that is, the necessary fix would cost so much that it wasn't worth it. The Court, in general, is hostile to this view, to say the least.

    There's also the matter of 'deep pockets' and political correctness. Even with all the malicious hacker stories in the press, you still wouldn't get very many lawyers willing to sue some 26-year-old nerd for negligence in fixing a software bug; defense lawyer starts telling sob stories, and it's likely to turn the whole thing around -- plus, how much are you likely to get? An Open Source programmer isn't likely to have much. Companies like Red Hat theoretically have money, although most of it's virtual, Stock Market valuations that probably couldn't be realized. With BMW payments to make, how many will chance it? Microsoft on the other hand is known to have a pile of real cash, easily converted to your Actual Folding -- just what a plaintiff's lawyer likes to see.

    So no, I can't see open source being in much danger from negligence suits for software bugs. It isn't an attractive target for such suits, and a fairly strong defense is on hand. Bill & Steve might should sweat it.

  6. Keep in mind the audience on The BSDs in the WSJ: "Help Build the Web" · · Score: 1

    WSJ isn't aimed at geeks -- although I think they'd be surprised how many pay attention, especially after the RedHat IPO!

    For the audience this is aimed at, it's a nice short 'executive summary.' Leaves out a lot of things some of us consider important, but that's the nature of the beast.

    Don't expect a mass newspaper aimed at financial types, managers, etc. to cover (or be interested in) all the fiddlin' details. Instead, rejoice that they're paying any attention at all -- and be joyful and thankful that the errors are of omission. What's there is right, which is better than 90% of today's journalists can say.

  9. So start a body shop! on NYT on High Tech Unions · · Score: 1

    Look, several folks have commented on working for a "temp agency" that takes most of what the corp pays for their services, leaving them with 30-35% (about typical.)
    Even the worst-case union dues are a teeny fraction of what a body shop skims off. So, start your own body shop.

    Being a temp is a good position -- and the ideal would fit precisely with the Management Theory of the Week, which is "outsource it all." Fine. Go to company xx and say, "Hey. Give us the job descriptions, fire HR, and sign the contract. We'll screen the people and see the job gets done." They'll love you for it!

  10. R&D Money on Caldera Evidence Might be Thrown Out in MS Trial? · · Score: 1

    Lots of us are unhappy that Microsoft did what they did--but that isn't the point.

    There may be some Microsoft-haters (many!) who just get off on insults, but you aren't getting the point, or you don't know what you're talking about.

    Caldera (and DR before them) didn't want Microsoft to spend R&D money accommodating Windows to DR Dos. It was never requested. If it had been, Microsoft would have been fully justified in sending them a copy of the cartoon. You know it: three little guys ROFL, and the caption is, "You wanted WHAT?"

    What DR wanted, what they should have had, was the same deal every other software writer got: a copy of the Beta, so DR could spend the R&D money making it compatible.

  11. Copper PCB antennas on Fractal Antennas more efficient? · · Score: 1

    NASA does a lot of this. It's a little more complex than just printing it, though, and I haven't seen any fractals (my subscription to NASA Tech Briefs lapsed.)

    You have to have more than one layer, and it works best with slot antennas. A slot antenna is one of the solutions to Maxwell's equations that can be done; the length of the slot is the width of the wire, and vice versa. They use the technique to make antennas that are flat, for e.g. sticking on the skin of an airplane or spacecraft.

    Actually, it sounds like an ideal use for the fractals, and if the picture is an indication, that's pretty much what they're doing.

  14. Diplomacy Of Violence on Fighting the Techno-War · · Score: 1

    Bullshit.

    Sorry, Panzer, I understand from the above that you're a Serb and therefore emotionally involved. But don't listen too hard to that kind of stuff. The United States simply doesn't have that kind of forward-looking planning--we can't put it together, because we're always running in circles about something else.

    When we start seeing pictures of Milosovic, or Saddam Hussein, killing people because they don't believe the same, or because they're in the way, it makes our blood boil. And yes, some of us are aware that Kosovo is vitally important to the Serb mythos of existence. Don't overrate that understanding. This is a country where evangelistics can preach hellfire and damnation from the pulpit for nonbelievers, but if the mosque across the street catches fire, the preacher and congregation will both be helping folks out of the building--and are pretty likely to offer the use of the building for services until the Moslems can rebuild.

    The real root of this--besides what Jon has aptly pointed out, the attractions of Techno-War--go back to the fact that institutionally, the US feels guilty about not doing enough for the Jews during WWII, which in turn goes back to the multiethnic ideals of the US. True, we don't live up to those ideals, but at least the intellectual part of the US feels guilty about it and tries to do something, witness Civil Rights, et cetera.

    And there's plenty to feel guilty about. Pol Pot, the various idiots in South and Central America, Idi Amin, and on and on. Offer Americans the chance to blow the crap out of one of those jackasses and watch the volunteers pour in.

    The common name Warthog was not assigned out of affection, although the ones who use it now use it that way, a lot like most of us see geek and nerd.

    A lot of that goes back to what Katz is talking about. Curtis LeMay, arguing for establishment of the Air Farce as a separate service, promised Congress and the United States that air war could win in clean, painless ways--and we're now seeing (again) that that just ain't so.

    What the Air Farce wants is

    Here we go, into the wild blue yonder
    Rising high, into the sun
    Contrails white, rising to meet our thunder...


    That is, white scarf and shiny metal, clean sparks in a cerulean heaven.

    The A10 is absolutely the antithesis of this. It's ugly, it's slow, it doesn't fly very high, and it's meant to get down into the mud and support the troops. Asking an Air Farce troop to get mud on his boots is like asking one of Jane Austen's heroes to go into 'trade.' So they've tried to kill it any number of times.

We seem to have lost the abilities to damn with faint praise, and call people dirty names without actually saying anything overtly nasty, that were pretty well taken for granted not long ago. Part of that's because so many of us are young, and haven't learned to let things go right past us if badly aimed.
