Why do cryptocurrencies use hash-based puzzles to demonstrate proof-of-work? Why not some more intrinsically useful problem?

A short and sweet bit of Python code to test whether an arbitrarily large integer is a square, and to find the floor of the square root.

Most numbers that are representable as machine integers are not exactly representable as floating point numbers.

Could the Electron E1's spatial dataflow architecture be the future of ultralow-power computing?

What can you do if you didn't include a check sum in an identifier then decide you want to go back and add one but don't want to break old IDs?

Wallet Import Format (WIF) is Base58 encoded, which removes some easily confused symbols like 0 and O. The best font for distinguishing the rest of the symbols.
