I hope others can suggest a comprehensive but generic enough book, I don't have one.
You might want to take two books: a Unix one and a Windows one. On the Unix one, I can recommend the purple book, on the windows one... well somebody else please step up...;-))
If they get lucky and tag an exec or two before they're killed it might cause the record companies to back down a bit, seeing as siccing the lawyers on a poor student ultimately ended up with a bloodbath.
They won't back down. They'll just blame the whole thing on some first-person shooter and start clamoring for more restrictive laws WRT what software you can run on your computer. You'll then need a license to just buy a computer that *can* run games not specifically made for children (thanks to TCPA)!
BTW, I realize the whole WVMS within a WVMS thread is just ramblings, but my understanding of how VMs function indicates that that would not be possible. IIRC, a 486-class or better host processor is required to host a VM, and it only virtualizes a 386-class processor.
No, that's not true. The reduction to 386-class is only speed-wise. The numeric coprocessor instructions are still there, as are the other 486-class specific ones. How exactly they did it, i don't know, because 386-class and newer processors are not truly VM-capable.
OTOH, a truly VM-capable CPU like a VAX or the various cpus in the IBM 390 series actually *can* run an OS within an emulator within an OS within an emulator within...
Did you READ the word "suid" in that sentence? If I have a user account and can get or copy a suid binary somewhere I can write/copy over it (i.e. my home directory,/tmp...), your box is toast because I can make any program I like run as root...
No, you can't. You can make that executable SUID to *your* UID, but not root unless you are already root, but then where's the point?;-)
A SUID executable on a floppy probably wouldn't work, because if the floppy is user-mountable, all files on it belong to said user, so again suid to *you*. (I admit, I didn't try it with a floppy with an ext2 or minix FS, but AFAIR when the device is user-mountable, "exec,nosuid" is the default...)
I'd guess it's like with ships: You fall in the jurisdiction of the country that aircraft is registered in. Exceptions might be aircraft on the ground, or in national airspace...
Remember: a lot of ships fly flags of countries with very lax saftey laws - the only thing a country can do about one of those is keep it from entering its tree-mile-area (or was it 12-mile!?).
Example at hand: what the EU is doing now is trying to get its members to ban tankers they deem unsafe from their harbors - unfortunately only after one of those sank a couple of hundred miles off the coast of Spain with about 70000 tons of heavy oil aboard. Being banned, those tankers hopefully have no more reason to go near European waters...
I coulden't find an SSH clinet to run of a Revo - though there are several for the Netbook. and anyways SSH over a 2400 connection would take forever for the key excahange, and I'm impatient.
2400 baud is at least 2400 bit/s. Consider you have a very long key, say 2048 bits, on both sides, that's 2 seconds, just for the login. After that, you can have a compressed connection and just do the task. What the hell is the problem there?:-)
If you have a problem with the Revo, get a Palm Pilot, there is a SSH for that (Search for Top Gun SSH). You might have to have a screen session on another machine with a special terminal type for the palm session, but well...;-)
Apparently, the German site heise.de makes a profit, with very little banners and no popups. I wonder how... probably by offering lots of content with minimal bandwidth, while keeping their ad prices up... (sometimes you even see pages without any banners... !)
Go buy yourself a second disc and run a RAID-1 (mirroring) on it. Another way to go would be to make daily backups from the other disc, which is, in case of a failure, probably not 100% current, but if unmounted after the backup would protect even against the infamous "stupid sysadmin errors" of unwantedly rm -rf / 'ing (or similar) of the main drive... (I, myself actually practice the second version...)
That's something that's always bugged me. Why is it that the heads are allowed enough flexibility to touch the heads in the first place? Why not make them rigid enough so they stay in a fixed location relative to the platter regardless of air movement?
The problem here is tolerances. The heads are so close to the disc that they are basically touching it. The air is actually used like a lubricant in some bearing (call it ground effect). Imagine the engine of your car - what would happen if you ran it without oil? A hard drive with rigid enough head mounts to work at some other than the specified speed (or in a vacuum as another poster asked) would be heavy, slow and *VERY* expensive, if it even came near the data densities you find in modern hard drives.

As for the greyhound. The 20,000 pound chutes the army has aren't strong enough for a greyhound. any info on parachut clusters big enough for a greyhound. Also, they need a C5 to drop the bus from. any civilian operators out there?

Won't stick to anything except for itself.
Nope, Sorry. There are at least two types of Panzertape: one that cannot be torn and one that can. The effect that it sticks to nothing but itself is, I suspect, an effect of old age. (I've got multiple rolls, at least one sticks like hell to anything it encounters, the other does as you described..) AFAIK the spec of Panzertape was to stick to anything, including wet and/or slightly oily surfaces.
Actually, that wave travels at the speed of sound in that material. Finding a material with a speed of sound greater than the speed of light is left as an exercise to the reader.
Manufacturers spend millions of pounds developing these cars, but a wanker in an anorak ten years later knows MUCH better how to get the best ride/handling balance out of it, obviously. Do they bollocks.
Nope, now it's you talking crap. It's just a matter of optimization. Car manufacturers optimize their cars for the combination of ride smoothness, handling, fuel consumption, maintenance and a few other parameters they think they can sell best. Car tuners cater to people that want to sacrifice some comfort for better handling, or some handling for better offroad capabilities.
Sure, you can buy cars that do most things well, but be prepared to pay a fortune. For exapmple, look at the Audi Allroad in the Ski-to-the-max version by Willi Bogner. (Yes, you can buy that car!) The car has probably better handling than all american mainstream cars, with the possible exception of the Viper and the Corvette, but even then it gives them a run for the money (>400hp on a 4WD...). It does Offroad fairly well (no match for a real offroader, but when do you need it?). Most american cars might beat it with respect to ride smoothness, but that's a tradeoff for the handling. Fuel consumption, well, I think it's pretty good at that, except compared to much smaller cars. BUT: it costs AFAIK something around 100k Euros...
Now take the contrast: Get a Ford Mustang, tune it. Usually, it will be quicker, but not as smooth as the default. Forget offroad...
Lord Of The Rings is a first hint in that direction, IMHO. They released the DVD an the same day, worldwide. I think they learned it the same way the gaming industry learned that it doesn't pay to release a game in the US and only months later overseas - it just would be copied...
I mean, trading popular bootleg actress AI's could be the next big P2P rage-- who needs an old-fashioned nudie magazine when one can spend a few minutes downloading the actual Nicole Kidman, Gwyneth Paltrow, and Mira Sorvino* on Kazaa and simply order them to engage in a hot lesbian threesome just the way one likes it, on one's own computer?
*-names of current real actresses used for effect, but I really mean popular CGI actresses of the possible future.
* It's going to be Really Cheap Real Soon. Stuff in this category can be prototyped, but expensively, and needs some huge breakthrough in production technology to be economically useful. In this category we have eInk, and polymer photocells.
Well, these polymer photocells appear to be cheap already, but not efficient enough. This time it's the other wa around..:-)
There's another angle on that figure. If you buy an XBox, they might lose $100. But, on the other hand, you inflate their sales figures, so they have more leverage to developers, telling them to drop support to other platforms because they aren't as successful.
Basically, in this way they're literally buying their way into a new market!
The last time I heard about the Simputer I was put off by the license, which treats the specs as if they constituted trade secrets. I
don't know how you can publish specs and still expect trade secret protections.
I guess, that was a year ago. Keeping the specs of your new gadget a trade secret makes at least some sense, because it gives you a head start on anyone who might want to enter the same market.
IMHO, it's exactly the contrary of what Microsoft is doing most of the time: publish insane specs to scare away any would-be competitor, then slip the release date until the specs become viable...
And then there's the fact that 1000 litres of water (or 1 cubic metre) weigh approximately 1000
kilograms (depending on the temperature), so it's also pretty easy to match volumes to weights.
Small wonder, looking at the fact that 1 kilogram was defined as the weight of one litre of water...
