This looks fantastic. I will definitely give it a spin. I've been tracking what I call "computational scratchpad" apps for a while now but haven't found one that fits my environment/workflow yet. Maybe Heynote will. Here are some others that I've looked at: * https://soulver.app Granddad of them all, Mac-only, proprietary, expensive * https://numi.app Mac-only, proprietary, semi-expensive.

The flip side to this is that Julia is a very capable general purpose engineering calculator and simulator. For example, calculating friction in hvac ductwork, voltage drop in long electrical circuits, solar gains for windows or solar panels facing various directions, cost/benefit analyses of thicker or thinner roof insulation and so on... These are all 1 to 10 lines of code so there isn't a big porting cost in... - Source: Hacker News / about 1 year ago

There are a bunch of these shared here over time. https://bbodi.github.io/notecalc3/notecalc https://dedo.io/ https://numbr.dev/ https://github.com/iaredreich/calcutext https://calca.io/. - Source: Hacker News / over 1 year ago

There are several free and paid apps that keep your Mac awake, however. I've used Caffeine on my iMac so I'm unsure if it still works with MacBooks, but I do plan to try. Source: 12 months ago
