As a side note: > I did all my calculations for this project using Calca (which is great although buggy, laggy and unmaintained. I might switch to Soulver) and I’ll be including all calculations as snippets from my calculation notebook. I've always wanted an {open source, stable, unit-aware} version of something like this which could be run locally or in the browser (with persistence on a server). I have yet to find one. This would be a massive help to anyone who does systems design.
