Implementing a Tor relay from scratch in golang (2015)
Update from the author, over a decade later: Go has improved and so have my own skills.

You Compiled This, Driver – Trust Me
I was incredibly inspired by Tomasz Stachowiak’s hack of GCN . It made me wish I owned a GCN machine of my own to start trying insane things with. On the other hand, I dooo own an Intel Haswell GPU , and they dooo publish some really dense documentation that’s allegedly enough to write a complete driver with.
