comment Alternative to A4988 stepper motor driver?
@ConnorWolf, quite right! I didn't realize this until (what is now) many years later. I've since 'graduated' to using the Smoothieboard, which uses A4982 stepper drivers that have better thermal qualities along with some thermal vias placed underneath. They explicitly say not to put heat sinks on the top of them for precisely the reason you pointed out.

comment Throwing Balls into Bins, estimate a lowerbound of its probability
@DouglasZare, I've verified your calculations, you're correct. Serves me right for not being more rigorous.

comment Is the EmDrive, or "Relativity Drive" possible?
@rob, Ron Maimon is banned until Aug 24th, so maybe he'll be kind enough to update his response then. Until then, John Baez has a response. Baez's response seems to just reinforce what Maimon wrote above.

comment Shortest distance between two line segments
There is a typo in the initial 'if segments_intersect' condition on line 6. It should be '...x22, y22): return 0' not '...y22, y22); return 0'. Also, be wary of integer math vs. floating point math. Thanks for the code snippet, besides the bugs, worked for me!

comment What does the Star operator mean in Python?
To give some motivation coming from a C background, the * acts in an analogous way as the * operator in C, in that it 'dereferences' the variable. In python context, this means essentially 'removing the outer braces' of arrays or dictionaries.
