Voyager 1 and New Horizons. You are ignoring heat output. Curiosity's reactor produces 2kW of heat and 125W of electricity. The heat is more important - it is what keeps the rover from dying at night. Heat output is really useful for

Declarative programming is a great one, almost a magical experience. "It feels like I am sitting at the controls of a quantum computer. I've got all my qubits (terms) all wired together in some complicated expression and when powe

Counterpoint, object.next() was removed from python3 and replaced with next(object). It both modifies state and returns data. I really prefered next() as a method since it does change the state of a generator.

Grepping the PKGBUILDs on Arch looks quite a bit different Official: 547 out of 5115 use cmake. Unofficial: 5167 out of 47069 use cmake. A lot of these offer plain Makefiles too, but cmake is decently popular and hard to dismiss.

I'm pretty sure any sort of practical space based radiator system would not use circulating coolant but would probably use heat pipes. No moving parts and for large systems you generally use many small pipes in parallel. Combine thes

If you use Emacs, I've heard great things about used xkb to remap spacebar to control, and using xcape to make control generate a space when tapped. It sounds messy but now you'll get emacs thumb instead of emacs pinky.

You are probably still playing the original Humble Bundle (or launch) version. Update that. A while ago they added a frame rate limit and power use is reasonable.

It is a shame really. Declarative programming is so much simpler to think about and extremely powerful. I've been working on trying to make declarative programming more accessible and while I personally have seen 60x improvements in

Okay, that is pretty awesome. Some thoughts... greens are probably optimal for this because they are fast to go from seed to produce. And 100% of the output can be sold, with basically no wastes. Singapore is also optimal for greenhouses
