  1. Do I smell another ridiculous lawsuit? on Hitachi's Water-cooled Laptop · · Score: 2

    So the water won't ruin your electronics, it just runs around the plastic panels and into your lap. Having seen a bit more discussion of that McDonald's scalding-coffee lawsuit today, I'm wondering just how hot the water can get at the CPU? Especially the last little bit after the rest has leaked out? Are we going to have someone suing the manufacturer because they were too dumb to shut the thing off and get it out of their lap when it started leaking, and got hurt by that final blast of steam and hot water?

  2. Re:spring a leak? on Hitachi's Water-cooled Laptop · · Score: 2

    Air conditioners, cars, toilets, any hydraulic systems...they spring leaks all the time.

    It depends on the sort of air conditioner you are talking about. I've never seen a self-contained window unit leak - nor an electric refrigerator or freezer. All the plumbing in these is metal, with welded joints, and the compressor motor is sealed in with the refrigerant, so only two wires come through the case. These just don't leak unless there is major mechanical damage. Automobile A/C, OTOH, leaks all the time because there shaft seals where the compressor is driven by a v-belt and pulley, plus rubber hoses, etc.

    So if the laptop cooling plumbing could be built like a refrigerator, it would be leakproof unless you really smashed up the computer - and then it wouldn't matter. Of course, making a water pump without shaft seals is quite a lot harder than making a leak-proof compressor. You can't have the electromagnets under water, but maybe you could have a combined rotor and impeller sealed into the pipe, with the electromagnets around it.

    Or maybe you should just fill the laptop cooling system with a refrigerant. You might not even have to have a pump in this case - the mechanical power input might be the pressure difference between the hot CPU and the cool heat dissipator. The tricky part is that this would probably have to work "upside down", that is it's likely to get tipped so the cool end is above the hot end...

    I would say "a few", not "many". The vast bulk of their production was smaller boats for blockading Britain.

    This was damned fortunate for the US after Pearl Harbor. All the coastal shipping was completely unprotected, and it took several months before antisub patrols became sufficiently effective - long enough for a sub to cross the Atlantic, use up all its torpedos, go home to get more, and come back. But the Germans didn't have enough subs capable of making the trip, or many "tanker" subs to resupply the little boats, so the number of sinkings was limited. The panic and the disruption caused by keeping ships in port were pretty bad, though.

    OTOH, the strictly temporary spot shortages of petroleum caused by tankers being sunk or kept in port became an excuse for the government to severely ration gasoline. This doesn't seem to have been necessary in the US during most of the war from the viewpoint of total available supplies versus consumption, but it helped get the civilian population into making sacrifices for the war effort, and it conserved a lot of irreplaceable tire rubber.

    And [all US subs] had something the German U-Boats didn't have...showers.

    U.S. subs in the WWII era had to patrol the Pacific - which meant big boats capable of very long cruises, and the crew had to be kept healthy. So they had showers, and air-conditioning for the tropical areas, as good a food service as could be fitted in, and a reasonable amount of room to live in.

    Most U-boats were designed for short cruises out into the North Sea and around the British isles. So they were as small as possible (which helps evade detection, too), and if that meant cramped quarters and no showers, the crew could just bear it for a few weeks. After all, they could have joined the infantry instead and lived in muddy foxholes for _months_ at a time with no chance to clean up.

    Of course, as the war went on and the sub defenses multiplied close in to Britain, and on the approaches to the ports used to replenish the U-boats, the U-boats had to lengthen their cruises, and so things could get pretty uncomfortable. Furthermore, originally the boats would surface every night to run the diesels and recharge the batteries - crewmen could lollygag on deck during this, the hatches could be opened and some of the smell blown out, and if it wasn't too cold they could take seawater baths. But then someone (a Brit, I think?) invented radar small enough to mount in an airplane, the Americans manufactured thousands of large long-range airplanes, and once enough radar equipped bombers were on patrol, surfacing anywhere near the shipping lanes came to carry a high risk of being bombed. So the Germans invented the snorkel; now the U-boats could run the diesels while submerged, with only a periscope and air intake pipe exposed. These were undetectable to radar, but the crews suffered... For safer areas, the Germans also provided radar detectors, so the subs could surface as long as they could dive quickly when the detector pinged. But staying ready for a fast dive = keep most of the crew below...

    if you define it as a self propelled flying contraption I think you've got to go with either Lilienthal (German or French?) or Zeppelin (German). If you define it as a heavier-than-air flying contraption that can come back to ground without being smashed to pieces, it's definitely the Wrights. Lilienthal wrecked several powered airplanes while the Wrights were still flying kites and building wind tunnels. But the Wrights expanded their box kites into an airplane slow, stable, and tough enough that by being very cautious they managed to teach themselves to fly without killing themselves or wrecking it beyond repair. (Their very first flight did end in a tailspin and a crash - but from 8 foot altitude and a quite slow speed, so no one hurt and the plane was repaired in a short time. Their second flight the next day, with a rudder added to prevent tailspins, should be counted as the first successful heavier than air powered flight.)

    Almost every pilot since then has had the advantage of learning from an experienced pilot. But someone had to be first, and it was the Wright's motorized box kite, and their extremely systematic step-by-step approach, that made do-it-yourself pilot training possible.

    This article was about when there is an actual signed contract between the corporation buying the software and the software vendor. Under those circumstances, it _might_ be possible to negotiate away the "We are not responsible for anything but putting the software on the CD" clause. However, in exchange the purchaser probably gives the vendor considerable control over the environment in which the software is run. No one can guarantee that software will run properly without knowing what computers it will run on, how they are configured, and what other software is installed on them.

    But if you really want to get Linux under a commercial-style contract, I'm sure you could find some vendor to sell you support for so many copies installed at such and such a site, on such and such computers, with a list of other programs approved to work with it - and they'll throw in install disks too... Then if they don't get the software working, you might be able to sue for breach of contract, unless the contract forbids this.

    I suspect you'll actually have an a better chance of persuading a small OSS vendor to write a contract that does provide penalties or allow breach-of-contract suits for nonperforming software. The reasons for this are both good and bad:

    1. Suppose it turns out that the only thing that will make all the programs the customer needs run together is a little code change in the operating system? It's hard to imagine MS changing Windows just for one customer, especially after they've already got your money, but people do write patches for Linux just because they want it, whether or not it ever gets into the official source tree. Satisfied customers don't sue.

    2. It's likely that a big, complicated lawsuit against an OSS support vendor cannot pay off, because the whole company isn't worth the legal expenses. You'd wind up owning the vendor, but owing the lawyers a lot more than the vendor is worth. OTOH, MSFT could pay $10 billion cash without blinking. It would take 10 years of legal wrangling before you got any of it, but there are many people who would be willing to gamble, even on a poorly-founded case. So MSFT will probably insist upon contract clauses severely limiting the damages you could ever recover...

    So the "militia" clause expressed a hope (not a law) that the citizenry would arm themselves suitably for military operations, just in case it became necessary to call on them. (And many indian wars, as well as the successful defense of New Orleans against British regulars in the War of 1812, were conducted primarily by men who joined up for just a few months.) The binding main clause says simply that the federal government should not interfere with individuals obtaining and owning "arms".

It came closest in "Miller vs. US", where it decided that there is no right to own a sawed-off shotgun - confusingly, this decision went a ways down the road of misinterpreting the first clause, but then finally decided that the weapon in question was not covered since the military doesn't use shotguns. By the same logic, "Saturday night specials" (the cheapest, lowest quality handguns) wouldn't qualify either, because real military forces prefer weapons that don't blow up in your hand when properly used.
