Pumping gasses involves friction between the gas and the walls of the pipe, which means you have to put more pumping stations in, which means using up power to pump around. Friction will always use up more energy than transmission losses over anything other than the most trivial distance.
The problem is that reusuable spacecraft has proven to be a mistake. It costs more to develop something which can be used multiple times, and then it costs more to individually produce components, then it costs more to do the recovery & restoration. When you have a production line, like the pre-shuttle rockets, and like ESA has, then you can concentrate on producing reliable & cheap components. It worked for Henry Ford, and it works for spacecraft.
You can put H2 in a pipeline and ship it far further than is practical for electricity.
We can ship electricity all the way from Quebec to California if we want. The only reason we don't is that there isn't any need to ship power that far, when there are places with excess power inbetween. However if it proved neccessary, it would happen, and with less losses than pumping gases around.
They don't even have to do that. As long as there is opposition to the DoJ plan, then the judge can't accept it as a mediated settlement between the parties. As is pointed out several times in 12 Angry men, they could have declared as a hung jury, but they continued until all 11 were convinced.
Actually, there aren't any more cameras in Britain than there are in the US. The only real difference is that in the US there are a lot more malls, while in Britain most shopping happens on streets.
I'd have to agree with this. There are two major problems, the first being that the users don't really know what they want and the second being that almost always, the problems being solved are new problems, and therefore it's difficult to know what solution will best solve the problem.
OTOH, control input is far less clear-cut. For example, moving files around directories will almost always be much faster using a GUI than a keyboard. Initial context setup takes some overhead (bringing up the source and destination folders), but after that, dragging files around with the mouse will beat the fastest touch typist every time, especially for longer file names.
Ignoring the biggest & hardest part doesn't exactly give a fair comparision. Using a modern shell with filename completion eliminates the 'longest filenames' worry, so basically you're comparing typing speed with the ability to select files from a GUI window, and IMO, generally typists will be able to select faster than GUI users, because they only need to type, while the GUI user has to read the filenames too. If you're going to select by criteria other than the filename, eg last modified time, then the command line user is ALWAYS going to win, because find . -mtime +1 -print is much easier to type than the GUI equivilants.
Yeah, that's why I said consider using the DS1990A. It's not suitable if there is any possibility of someone being able to tap into the bus. The SHA-1 button (DS1963S) is very closely related to the DS1963L, they're both designed for monetary applications, and therefore both secure.
Of course if you need more than 4 gb of Ram you also need programs that can handle that, and I know of no such thing.
Not neccessarily. There is going to be more than one process in existance, each of which needs memory. If you have say 8 Gb of physical ram, you could have 2 programs, each one of which access 4 Gb.
I remember using a system which didn't do SMP, each processor had it's own private memory. Basically once a process was created it either ran on that processor forever, or it would be swapped to a new processor. In this case obviously no single program could be allocated all the physical memory, but it was still useful.
Have you seen/head the Three Dead Trolls in a Baggie sketch "Behind the Scenes @ Microsoft". Flash version here, or mp3 version here. Very highly rated, as is all of the Dead Troll material, Wes obviously has a highly tuned sense of humor about technology.
Also these are all hardware devices, which have a finite cost to copy. If you have to pay $20 for the hardware components, then adding on $2 for the licensing isn't a big deal. If you are intending to distribute the software free, then $2 is a big deal.
If all you want is local authentication, then you can consider using a simple serial number button like DS1990A, which costs about $2. If you want remote authentication, I'd probably consider a DS1963L, which is about $10, but supports better remote authentication.
A company will suddenly discover they can't legally run Office 97 and they need more licenses - MS won't be selling Office 97 or 2000 licenses then, so the company HAS to upgrade to Office XP, with the fancy anti-copying features.
And at this point companies will start wondering if they should upgrade to Office XP or investigate an alternative. There is a huge difference between buying 100 new licenses and buying 40,000 new licenses when you're happy with the earlier product.
You can't really compare the people who knew about computers in 1976 and the people who do in 2001. Someone who knew about computers in 1976 was almost certainly technically skilled and could provide an informed opinion. In 2001 the majority are point and drool who think that AOL is the internet and that Gates invented the technology they use.
There isn't really any mathematical difference between the master key and a session key encrypted with that master key, as one can be transformed to the other. That's why, after the session key is know for a disk, it's possible to establish what the other master keys are.
I've said this before, and Americans don't tend to belive me, but in practical terms, America is arguably the least free of any western nation. If you don't belive me, try and buy a Cuban cigar, join the political party of your choice, or drive down certain highways with dark skin and a large amount of cash.
However there is a big question about what 'pr0n' is. Europe has a much less fetish about simple nudity, and therefore images of nakedness are not hard to come by. Would a picture of a woman's breasts be 'pr0n'? Many of the British tabloids have a daily picture of a topless woman.
Except that all cell phones have variable output. If the signal is too strong, then they'll simply broadcast with lower power, giving exactly the same amount of radiated power as would have with the original antena.

Actually mainframes went away from water cooling, starting with Amdahl in 1979. Nowadays even IBM's highend mainframes are air cooled.

If you stuff it into a metal cylinder then you're going to have a much lower density than either the liquid or the solid.
If you've got solar energy, you're better putting it into batteries rather than the losses involved in hydrogen.
Actually C.W. McCall was first, 1980 was when "Good Ol' Boys" hit the charts, while "Convoy" was 1975.

They may well be reasoned findings, but your website isn't going to win any converts. It makes you look like Robert McElwaine.

Except he didn't know the difference between hyrdocarbons and carbohyrdates, and thought that the comets would have made good food.
Velikovsky was an ignorant nut, and the very few things he got right were co-incidences.

I think it depends on the individual. Some prefer software, some hardware. Either can be exciting to someone who is interested in it.
However there is a big question about what 'pr0n' is. Europe has a much less fetish about simple nudity, and therefore images of nakedness are not hard to come by. Would a picture of a woman's breasts be 'pr0n'? Many of the British tabloids have a daily picture of a topless woman.
