There are many industrial methods for the production of hydrogen and that used will depend upon local factors such as the quantity required and the raw materials to hand. Two processes in use involve heating coke with steam in the water gas shift reaction or hydrocarbons such as methane with steam.
CH4 + H2O (1100C) -> CO + 3H2
In both these cases, further hydrogen may be made by passing the CO and steam over hot (400C) iron oxide or cobalt oxide.
CO + H2O -> CO2 + H2

I have seen Propriety software that has the CDs sealed, and with a prominent notice on the outside of the CD case reading 'By unsealing this CD case, you accept the EULA listed here (or in the manual)'.
I don't know what the legal situation is, but at least it warns you about the EULA before you install it.

Naive question,
but is there much difference between CodeWeaver's Wine, and Transgaming's WineX?
I take it they both submit code to the main Wine project, but have custom extensions that aren't in Wine. Can I install both, if I want to run both MS-Windows apps, and MS-Windows games?
Have you considered that it is very impolite, when abroad, to start a conversation in English, without trying the local language first? Even ifyou can only manage 'Hello, do you speak English Please?'
If English wasn't my first language, I'd be inclined to ignore someone who started talking to me in English, or even reply 'Sprechen Du Deutsch?'
I'd like to see a law that ensures all spam/unsolicated bulk email has -
A correct from: and replay-to: addresses
Correct relayed-by: headers
A 'X-UCE: Yes''header
If such laws are passed, then filtering (either at sendmail or mailclient level) will get rid of most spam, and it would be easier to complain to the spammer, not that would do much.
I'm not holding my breath for such laws to be passed though....
They could use the Browse-ID string to send back a 404 to non-MS browsers. Anyone brave enought to try this on a MS browser, or change their browser's ID string to check?
However, a reputable ISP would remove any account (homepage/email etc) used for spamming/virus attacks. I haven't checked the site myself (using a Uni's Win2000 box, with MSN messager installed), and don't want to get into trouble for knowingly releasing it on thier machines.
Erm.
I'm work for a computer consultancy, that specialises in embeded systems. Of the projects I have worked on, one used a 505 CPU (basically a 6502 with I2C and a D/A-A/D unit), and another (a credit card reader) used a bank-switched Z80. AFAIK most EFT-POS terminals use Z80/6502s and bankswitching
I get a distenct impression that the hardware guys would prefere to use a $2 CPU rather than a $10, and then fail to recoup the costs as the softies find them a pain to code, leading to longer development time.

I use file foo, if I've don't know what type of file foo is. It uses magic numbers and heuristics to make a 'best guess' at what the type of file it is, on recent linuxes it tends to make a good job of it.

What the previous poster meant was, that
1 molocule Hydrogen (H2) + 2 of Oxygen (O2) gives
2 of water (H2O).
If Slashdot accepted PRE, SUPER, and SUB tags, this would be a lot clearer.
You are right, it takes a lot of energy to make Hydrogen, but according to Web Elements the normal approch to making Hydrogen is stream + ( carbon or methene), electrolsys of sulphuric acid (SO4+ goes through a complex system, and releases Oxygen, but is far more conductive that water) is too expensive, but it might be different if you want an oxygen supply as well.
The reactions above produce carbon dioxide, so unless its aneroibic methene, Hydrogen rockets will still produce excess CO2.
Anyway, for space launchs, the rocket must either be self powered, or doing atleast the escape velocity when it leaves the end of the launch-rails, which, for the Earth, is 11km/sec, well above the speed of sound, so unless you lauch from the top of a mountain, there will be too much atmospheric drag for non-self powered lauches.
To determine the escape velocity use this formulae
sqrt(2 * Gc * M / r) (from Astronomy 120)
Where Gc is 6.6725e-11 kg-1m-1s-4
M is planent's mass 5.9 72e24 kg for Earth
r is distance of launch from planet's centre (6.378e6 m)
Could someone explain why life is impossible on Venus. I know that it is 400C with suphuric acid/carbon dioxide atmosphere, which will stop any life from starting now.
But this would of gradulary developed, Venus started in similar condtion to Earth, therefore any life that managed to get a toe-hold on Venus would have had time to adapt their bio-chemistry in a similar way to those of the Earth's sub-sea vent creatures (~150C, high sulphuric acid concentrations).
I have heard that 'Oxygen destroys naked DNA'. Therefore there can be no DNA-based life on Sol 3, but when we look at Sol 3, we are hard-pushed to find somewhere where there isn't life of some sort.
Thanks,
I think that was the painting I was thinking of. I confused teoma.com by searching for a pre-raphaelite painting of Venus.
BTW, According to Dictionary.com clam-shells have the genus name Venus, or Veneridae.
No,
she was the Venus, Roman goddess of love.
I take it you are refering to this. There a also another painting, with Venus standing in a clam-shell, with a tree to the right, and naked cherbus in the background, but I can't find it.
Its kinda like
Le Printemps (The Return of Spring), 1866, but with more background.
Kyoto is an agreement for all countries to return to 1990 levels of producing CO2. It takes serious investment of money to achive this, so if the US doesn't, but all the other industrialised nations do, then the US has a major trading advantange (unless the WTO sactions tarrifs against the US, which I'd doubt will happen). The US saying they won't ratifiy Kyoto almost caused the Japanese not to, which would have caused all other contries in turn to pull out. Global warming is global problem, all countries need to take action to prevent it.
BTW The USA produces more CO2 per captia that all the other industrilised countries.

Last time I checked the LinuxBIOS page, there was talk of creating a minimal Linux kernel that would do the basic init stuff, and then replace itself with the real kernal on the boot drive.
Is there any reason why they could not modify LILO (or GRUB, etc...) so that it could do the init stuff, and then load Linux/BSD/M$-NT?
If this is totally off-beam, that I should point out that all thought I'm a programmer, I've never studied PC raw hardware, so my knowlage of a PC boot process is basically
Bios inits hardware
Bios loads MBR from first boot harddrive
MBR loads partion boot sector
Boot sector loads IBMBIOS.SYS etc (if your going to DOS), etc..

When ripping, I start CD-Paranoia to rip all tracks into invidiual files, and when it finishes the first track, I start the script above.
I find this handy as CDParaonia runs a about 1x speed, and oggenc about 0.25x. (My machine is getting well past its prime), thus I can rip a few CDs in an evening, and then leave the machine to encode whilst I am at work
I'd suggest writting another script that uses eject -c and cdparanoia to cycle through your CDs

Brazil uses (used?) cars powered by ethanol (natural alcohol). Petrol cars can run on this with out too much modification. The alcohol was produced by fermentation of sugar cane, presumably the low-grade stuff you get after molasses has been extracted. Thus there was little enviromental damange; just the extra land and fertialiser used to grow more sugarcane.
