Yes, I've learned that Heynote is lacking some documentation. Will improve that. Math.js (https://mathjs.org/) powers the Math blocks, so what's supported by Math.js should be supported by Heynote, with the addition of currency conversions (exchange rates are updated daily). > How to convert between fahrenheit and celsius? This should work:

  10 celsius to fahrenheit

This is awesome! I currently use numpad[0] for this, but would much prefer a local app. I would love to switch but the only thing holding me back is lack of Vim support. Are there any plans to add Vim keymap in the future? 0: https://numpad.io/. - Source: Hacker News / over 1 year ago

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.

They were impressed enough that the hiring process ended up being just a few interviews, I've been there for almost a year now, and it's been pretty good! If there's... - Source: Hacker News / over 1 year ago
