I mean to write a more comprehensive Bitcoin (a type of cyber currency) post in the future, but in the meanwhile, there's this...
I got my first bitcoin. It was sent to my address "15fszyyM95UANiEeVa4H5L6va7Z7UFZCYP".
I did this by running a "mining" application on my desktop.
This idea of "mining" is one of the philosophically interesting bits. Bitcoin is a currency, with exchange rates (currently $7 per coin). Instead of giving out coins for free, it gives out coins for some meaningless crypto work. Since my hardware is more efficient at crypto than the average person's, I can make a slight (very slight) profit running mining software.
