Do you have an idle cluster? Can you spare a couple core-years?

Help me bruteforce some test vectors for RSA key generation edge cases!

Here are the instructions, it's just a matter of running a single self-contained cross-compilable Go binary that will report the results autonomously.

ダイソーのエアポンプを早速分解。
ICのマーキングがないけれどパターンから推測するにU1がコントローラー、U2がHブリッジとするとR4, R5のところに位相をずらしたパルスいれてあげれば任意の周波数・デューティで駆動できるんじゃないかな。
