I was configuring an openbsd box, unpacking ports and sources. I cd/usr and tar xzvf ports.tar.gz. I now had/usr/ports and all was well.
Then I tar xzvf src.tar.gz, but it didn't create a neat/usr/src dir. Instead it proceeded to extract directly to/usr. I quickly noticed and interrupted it. Ah well. I scroll up to find what it extracted before I stopped it, and rm -rf CVS Makefile bin
Of course, bin was/usr/bin as well:P
Fairly trivial to fix, but with ssh/scp/netcat/everything gone it was quite an annoyance.
My preference is C, binary file formats, networking protocols, crafting elegant solutions for multiplexing IO.
Be careful. Binary file formats are great for performance and compactness, but for extensions and conversions, a company can suffer greatly.
Reserving 16 bits for some serialnumber might seem sufficient for the estimated five year life span, but then after 20 years of business you run out. Maybe you could convert the file into some other format? Oh wait, what does that fourth bit field that byte your C code calls 'CXXT7' signify again?
Do you think ahead? Do you include ways of extension later? Do you document your formats so well that any idiot who has no experience with the system can write a clone of it? Even the little hacks that you include later? Do you make sure each company gets an updated, hard copy of this documentation, and explain to them that they should keep it archived so they can show it to a new generation of programmers long after you've retired?
Terminal emulators for interfacing ancient systems isn't really rare as I'm sure you've encountered. I blame you if we in the future run Bochs with Windows with KidSockWare2k-clients.
{unless Disney added enough of their own new material to constitute a new work; unlikely, though}
You mean like...animation?
I don't see what you're complaining about. Disney didn't copyright Carlo Collodi's Pinocchio, they copyrighted Disney's Pinocchio. You can copyright ajs318's pinocchio, as long as you rip off Carlo rather than Disney. If a court decides otherwise, it's not a public domain issue anymore, it's corruption.
Why do all these comments get modded up? Would you mod up someone who said "I don't want RAID support in Linux, I just want an OS that lets me read my mail"?
"I don't want an arpanet with scifi mailing lists, I just want to exchange military information!" "I don't want a computer that plays pong and does spreadsheats, I just want to crack german codes!" "I don't want to melt rocks and make tools, I just want a nice heavy one to throw at my enemies!"
Googling a bit gives us the statistics of West Virginia Coal association (around 164 million tons in 2003), and trace info on west virginian trace amounts of uranium in coal (1.59ppm mean value). This might be a small fraction, but it's probably accurate.
So we have 1.59 mol uranium per million mol coal. I'll also assume that a ton is a metric ton and that coal exists entirely of carbon.
164M tons at 12.0107 g/mol gives us 13654491411824 mol. At 1.59ppm, we have 21710641 mol of uranium. At 238.0289 g/mol, we get 5167132640g = 5167133kg = 5167 tons.
Looks about right. Now let's do a rougher world estimates. This site says coal accounts for 93 Quadrillion BTUs. The number of BTUs per ton of coal varies, but according to Wikipedia's Coal entry, it's around 20M BTU/ton, so 4650M tons of coal. We'll still assume 1.59ppm U. Doing the same as above gives us 146515653621g=146515 ton. Since we used estimates and estimates of estimates, we'll just say "over 100,000 tons".
The usage of uranium? 42,500 tonnes. I suppose that's different fron tons, but screw that, I'm tired.
So yes, if my calculations hold, it's true. There is a lot more uranium in the coal than what we mine.
Like you say, the simplest games aren't instantly easy. Text-only RPGs are certainly no exception. They require knowledge of data structures and grammar parsing, or you'll end up with a bigass tree of if statements, and thus probably a rather stateless environment.
Who says you have to worry about eye candy in graphical games? I'd start off with a bouncing ball and then make Pong out of it.
Are you saying whitespace and linebreaks should be part of the language? Should you be unable to indent with four spaces instead of a tab? Should you be unable to wrap a long line into two? Should "c = a+b" be illegal, and "c=a+b" accepted?
There's silver in some kinds of cake decoration too (additive E174). Of course, the amounts are a lot smaller, but I wouldn't let the kids suck on the shiny things unless their hero is Freakazoid.
You're underestimating 3rd world countries. When National Geographic shows people living in trees or mud huds, it's because they document tribal people, not because it's representative of the population. 3rd world countries have buildings, cities and electricity like other places, only perhaps a bit less of them.
For a linux based wristwatch it doesn't matter if it's 24h or 24h39m. The battery won't last long enough for it to matter. But then, I suppose they could run an ntp daemon on it;)
You gobbled up 25% of the network storage space, for crying out loud! The next time you find yourself on 5mb hard limit quotas with zealous program blocks, port 80 run through a transparent whitelist proxy and all others dropped, thank yourself and your kind for making it necessary!
They shouldn't have to ask you to not perform denial of service attacks on their servers. If I was your teacher, I'd write you up even if I could delete it.
Completely bogus interpretation. What if the wlan card requires drivers that are not in the kernel (like mine)? What if it there are drivers for FreeBSD that could be ported? What if the specs are open so you're free to make your own driver? What if you can run VMWare with windows drivers? At what point does it work or not work? What if everything works flawlessly except tv-out which is black/white? Does it work then?

Yes, BitTorrent is probably used for a hundred times more legitimate traffic. 0.1% as opposed to 0.001%.
But seriously... I can't remember when I last downloaded a distro on cds. Will we see netinstalls using bittorrent soon?

I hope you mean third world from the sun, otherwise I think you've missed the main target group for western movies.

Where's your geekness? A wml cgi script on apache that calls wget to place your order; whip up your cell phone and wap yourself a coke.
I could have said the same thing about ADSL in the 1970-ies.

Don't let the truth get in the way of a good story :)
The deepest people have drilled is 15km. If that's 35%, the world is indeed getting smaller.
No, I can't see the point either.

If not, you can easily do ascii art with it.

You're going about it all wrong: just speed it up to 6 hours and listen to it while you sleep the day before the test.
