I start downloading the 8-bit games movie (pretty damn cool) when there were only 3 comments posted. Starts out dloading at 45 K/sec, but steadily drops... and drops...and drops until it's hitting 6 K/sec (3/4 done) as the number of posts reached ~20. It's currently going asymptotic, constantly saying "3 minutes remaining"...
Since there were around 140 different cypher-letters
140 encoding characters? From what I can see of the encrypted message, there are roughly 600 characters in the entire message. Once you get to the point where the number of encoding characters reaches the number of message characters, isn't the entire information content transferred to the encryption key, and you the message itself becomes garbage?
I mean, I can come up with an indecipherable code: replace the first letter with '1', the second letter with '2', etc. etc. Then my encoded message becomes "12345...", and my key says
1=H
2=E
3=L
4=L
5=O ...
Yeah, it's a cipher, but only because I've removed all the information from my message and put it in the key. Isn't actual cryptography the art of retaining information, but making it really hard to read? Frankly, I'm amazed Gil Broza was able to solve something with so little information left!
This particular school (CMU) has seen a marked increase (from 10% to nearly 40%) women in the freshman CS class in the past three years
Yeah, they told me that too when I was there. After four years wandering around Wean, I decided they were lying. It's my experience that the number of women in hard science/engineering is, sadly, staying more or less constant.
even the military isn't stupid enough to build a system that will be around even when there wouldn't be anyone left to use it.
Hardly.
I know folks who worked at Boeing during the cold-war years. The coffemakers on the B-1B bomber (not the flashy stealth one, mind you) were required to be so durable as to continue to function after an impact that would kill every person on board.
Yeah, density increases with decreasing volume, but ONLY IF THE MASS STAYS CONSTANT. I GUARANTEE the guy didn't get the same amount of mass into one millionth of the volume.
Here are another few proportionality relations for you:
Gravitational force increases with mass.
Penetration resistance decreases with area.
Area increases with the 2/3 power of volume.
If he did increase density by 10^6, he wouldn't have been able to do any experiments on his crystals, as his sample would have punched a hole through his desk, the floor, his building's foundation, and would currently be sitting at the center of the earth.

Sheesh.
./ more often. :)

Should'a been reloading

They ARE that stupid.

I imagane that it could be loaded onto something a bit sturdier...
Yeah, but would you want to have a chainsaw-enabled webserver running around? I don't think that's what's meant by having a secure website...

ultrananodiamonds are 1,000 more wear-resistant than silicon, and 1 million times denser than conventional crystals.
A million times denser would give one cubic centimeter of the stuff a mass of several metric tons. What the article actually says is:
1 million crystals in Gruen's diamond film can fit inside the crystal produced by conventional methods
Which means that the crystals are a million times SMALLER, not denser.
