Man, I spend the first 30 min just loading the program into my head. Actual work gets done after that. This ‘code on the subway’ workflow sounds horrible.

See comic

It sounds like a better use of that person’s time might be doing requirements/design work on the subway. Probably less obnoxious to the people around as well.

I used to do Python coding lessons and practice on a 10" ThinkPad tablet on the subway.

It was slow as fuck but so is my brain when trying to learn code :'D
