I've been saying that I want to see more talk about space at Hacker conferences, and Part Time Scientists delivered in full force at Chaos Communication Congress last week.
Then Part Time Scientists software lead We Faler gave a very technical, but terriffic talk on space communication protocols.
Then there was a call to arms by Nick Farr on Building a distributed ground station network.
When you're done with that, spend the following hour with writer Cory Doctorow on the coming war on general computation. It's worth the effort.
