Pulling random data from /dev/random
Posted by Si in Programming on February 17, 2010
This is a shell script that will pull 5 random characters from /dev/random and print them out to standard output. It was created as the input component for a random password generator that I am currently writing.
Note on using /dev/random: as usual, using this source for entropy will give you pure randomness, though due to the nature of the random source (see Wikipedia entry on /dev/random) the script may sometimes lock up and fail to generate a complete output, as it has run out of randomness. If you are intending to use this alot, then it is advised to use /dev/urandom that doesn’t block, although that comes at the cost of a small bit of entropy.

Is that Tiberium in this product?
I came across this originally walking around Town, and thought “WTF is that Tiberium!?” and thought that maybe people here would be interested to see what looks like Tiberium in the real world. If you don’t know what Tiberium is, then I’m guessing you haven’t played any of the main Command & Conquer games.
Is this Tiberium at the bottom of the image?
Note: Sorry to the people at Sure, I don’t mean to pull your products apart
Edit: Here’s a link about Tiberium on Wikipedia for those who don’t know. http://en.wikipedia.org/wiki/Tiberium
