Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

NoteCalc 0.4.0
To the OP, congratulations for stopping procrastination. :-) I like the idea of your project,I'm often in need of a little tool to help quickly calculate some finance related data. In this case, I often launch a LibreOffice sheet but it is rather heavy for what I need. I'll give your tool a try.
If you are looking for having notecalc3 running locally, the github[0] repository has all the installation instructions (not found in the documentation)

Show HN: Heynote – A Dedicated Scratchpad for Developers
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. Has a Github and claims to be MIT-licensed but I don't see how you could build a working application with what's in the repo.
* https://calca.io Windows- and Mac-only, proprietary, not expensive, nice docs.
* https://notepadcalculator.com Web-based, not open source, hosted but uses local storage. You can optionally create an account to sign in and have your notes saved in plaintext on his server.
* https://github.com/bbodi/notecalc3 Web-based, open source, self-hostable. But it seems to save your document in the URL string itself, which means the URL gets updated with almost every keystroke. Worth it for quick calculations and very small notes, I guess.
* https://numpad.io Web-based, hosted, not open source. Also stores entire doc in URL, but doesn't update the URL bar the whole time you're typing.
* https://numbr.dev/ Web-based, hosted. Has a Github but is not open source and the repo does not have all the bits needed to self-host it. Stores entire doc in URL.
* https://github.com/metakirby5/codi.vim Vim/NeoVim plugin that is less like a "smart notepad" and more like Jupyter but with results printed on the right side of the screen instead of in a cell below. Supports lots of programming languages.

QwikTape: Do calculations, annotate like you would on a paper
I made a list of calculators like this which were shared here on HN over time https://gist.github.com/SMUsamaShah/6546011091d53380354484a3...
From these https://bbodi.github.io/notecalc3/ and https://notepadcalculator.com/ are the most programmer friendly (supporting <<, ^, binary, hex etc)

Some Things I Realized about AI While Contemplating Slide Rule Prices on eBay
Another paradigm are Notebooks. Jupyter style are pretty popular these days, something like Wolfram Alpha's step-by-step mode or this project recently noted on HN https://bbodi.github.io/notecalc3/ are all good examples. Plenty of people use spreadsheets to explicitly chain operations.
A specific operation is much less important than the context, dimensional analysis, getting order-of-magnitude or precision correct. Performing operations narrowly is probably operating on the wrong level.

Show HN: I made a web-based notepad with a built in unit calculator
Very cool!
This reminds me of the open source NoteCalc: https://bbodi.github.io/notecalc3/
It was discussed on HN, you might look there for inspiration: https://news.ycombinator.com/item?id=25495393

Show HN: NoteCalc
I answered here: https://github.com/bbodi/notecalc3/issues/6#issuecomment-749...
In a previous versions, only the changed areas were re-rendered, but the code was much more complex and error-prone, and it did not bring any performance improvement, so now I just rerender everything, still excellent performance but much simpler code.

Notepad Calculator
It's because it's not supported out of the box by the mathjs library I'm using: https://mathjs.org/
I agree that this would be nice.

Show HN: I made a web-based notepad with a built in unit calculator
Ha, yes, I was being nosy. It was quite easy to spot as it's the only XHR/Fetch request.
I was intrigued what you had used to build it, and if you had built your own solver (which you have), and what editor you used (Code Mirror) so went looking at the code. Interesting to see you left the source maps for production, made it easy for my sleuthing...
I experimented with a similar idea last year, but used ProseMirror/TipTap as the editor to enable rich text editing, and the MathJS (https://mathjs.org) solver. I also combined it with PouchDB and Yjs for offline editing and syncing between devices. Never finished it though, you have kept your nice and simple!
