I’m not sure on what nerd-level you put yourself, but I feel sincerely handicapped if I don’t have my computer at my disposal with my code editor and apache service running. It happens quite often that I come up with new ideas for programming or I just have the urge to test something out, and I’m on a computer where it’s not feasible to install all the software and services I need to test these things out. I actually have a couple pages in a notebook (the paper kind) covered with code snippets. I give you the solution.
