I'm researching seti for a final year comp sci project, and I've just handed in a draft about how its been secure, but how my distributed foobar will be open, and therfore more secure.
(dunno how to make it secure yet though)
Cheating is a big thing, as you can sell your work units on ebay!
500 units @ 25 euros and http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&it em=2064169353 and http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem& it em=2064990327
Lets assume that in the next 1000 years we havent wiped ourself out.
Let us also assume that the human race will continue to expand.
With a population of 10billion+, we'll need to spread out from earth. Space colonies in orbit, on mars, the moon, and jupiter's moons should all be possible by 2500, no problem. Given my 2 assumptions it's inevitable.
With that size civilisation, it's not a far strech to belive we could build as many orbiting solar satelites that we want. On board each station, convert solar energy into anyimatter. OK, you might get a 0.001% efficency rate, however with a large enough surface area, at a similar height of Mercury's orbit, you would produce 9E21W of energy, wirh 0.001% efficeny we could produce 1kg of antimatter a second. Thats a lot of antimatter.
Of course what would we use antimatter for? Answer: Convert to energy.
All antimatter is, in the long run, is an energy source. If we have a very effiecent battery, which can pack an enourmous punch for its mass, then theres no need for anti matter for general power production. For the times we specifically need antimatter, produce it in situ. Wont be as efficent (solar -> "battery" -> antimatter), however it will be a lot easier then hauling even a minute amount of antimatter arround the solar system.

No, however if you put the set the mirrors up correctly, You'd pump 1MW of laser into the system for 5 seconds (5MJ), then fire it in 1/10th of a second (50MW) - sort of like a capacitor.
Even if the system is only 90% efficent, you get a 45MW pulse for 1/10th second.
having an internet window open just at a random site makes it easy to take short 30 second 'breaks'
Cnn or something, a page updated with a short story every few hours. Whatever you do - DONT have slashdot, or any site where you can start typing (Forums, usenet etc). I am 1 1/2 hours into a coding session so far. I've opened one rxvt and typed "vi Lexer.java" - unimpressive.
Other tips I find help
Dont be hungry. Start getting hungry? Order a pizza (online).
Warmth. I find if I'm at home and dont put a pair of socks on I curl up in my seat, not very efficent
Have everything you need at hand, however keep your work area clear
Set a goal. Decide "OK, I'll work on this module until 3AM". If you have left it that late you'll be daunted at the amount of work you have to do. Quickly sketch a time plan, using no more then 2/3rds of your available time. Dont forget unexpected events (crashes etc).
Give yourself more time for ironing out missing semi-colons etc.
Dont get stressed, but be aware of the time. I did an all nighter in my first year in uni - had xplanet on the screen. The horizon moved over india, then the middle east, then greece. I liked it anyway.
Dont make last minute fixes. You'll break 5 other things.
Incremental backups. maybe a cron job, tar your files at least every hour, preferably every ten minutes.
Keep a paper version log. Write down what you've done so far - with a pen. It will give your hands a change of pace for starts.
Do pullups, go for a run, press ups etc. Every 20 or 30 minutes. Complete break for 5 minutes. Even if its just going to the local 24/7 to get some more caffine.
I use it because 1) I cant phone people in the middle of a workshop at uni 2) Mobile phone calls cost arround a dollar a minute to australia. ICQ costs arround a cent a millenium. Dont use MSN or AIM - I've got a semi-low number on ICQ.
"if you stand naked in your doorway and you hold the door closed with Scotch tape, can you complain about someone opening the door and then everyone seeing your naughties"
if you stand naked in your doorway and you dont shout out to the guy across the street that you are there, you cant complain about him seeing your naughties, just because you didnt tell him it was there.
The URL contains the Domino internal document ID (similar to a GUID) and I still can not understand how Reuters "guessed" that. Sounds to me like this is an internal leak...
the URL is still a URL. When dumb boss 101 uses dumb browser 4.3b, and types in "www.reuters.com" after being on that site, the page may be mentioned in reuters logs.
If their webserver is attached to the internet in any way, then anything it is "serving" is fair game, and should thus be protected appropriately.
While I'd normally agree, if its protected by some kind of protection (htaccess) - even if its really weak, accessing in would be cracking, same as if a door in a house is open, you still cant nick the TV.
Of course in this case google would have spidered the report before long and they cant prosecute an automatic robot can they?

Wow. In 100 years we'll have space stations that big. it's hardly Moon (x00miles+) size is it? Y'know theres a golf ball floating arround the Earth's moon - a moon of a moon?
In the UK, you can get Season 2,3,4,5 and season 1 will be out shortly.
I did have every episode from season 3 onwards on my HDD but as I replaced them with DVD's off they went. I only have a handful of episodes, all from season 6, on there now.
SG1 is one of those series where its worth going a week without food to watch the dvd.

Yup, sadly it doesnt exist any more - it was on the load tester (brak).
But thats nothing compared with the troll-report post

I blame the new server - its all different and backwards on that side of the country. They drive on the wrong side of the road too dont they?
Do I get another 30 mod points?
And how many computers did you say you have? Next time you post that you are going away for the weekend....

No laws been broken here.
Hmm ,set up a network of one way mirrors and lenses, storing the power of a 5 minute laser burst, then release it all at target of choice
now: well, let's click submit and hope people will understand this is not only easy and quick to use but also to acquire and install !
Not any more, now 5 billion slashdotters have hit the site...

Google covers the issue of"secret" web servers

A phone is easilly dropped and therefore no longer a distraction, if theres a problem. A kid isnt.
asshole probably can't even use a computer at all without wanting to shoot or gas it.
But to be fair, we all feel like that on a monday morning
