"What are you working on this week?" is a weekly thread since forever where people often talk about computing anyways.
I don't see why moderating posts should be fair. Better to remove a few good stories by accident than to leave up trash. You'll never have enough time to read all good ones anyways. They're very careful with banning though.
In Haskell types are used a lot as documentation and to make static guarantees about the program logic, not just runtime safety. If you're only worrying about illegal operations you practically don't need signatures.
In Darker than Black there are Contractors. They have a "contract" which means they can cast one particular spell, after which they have to complete their "contract payment" before they can cast again. That's often a simple but annoying task like smoking a cigarette or writing a poem. The spell and payment are different for each one. Nobody got to choose.
This is already possible, but it never was a problem. The GPU is just a slave to the CPU.
The biggest problem I could see would be when your computer becomes part of a botnet. Your computer could be used for brute fore encryption cracking. Again, this was also possible with just CUDA or OpenCL.
