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.

Muboard: Keyboard Driven Mathematics Chalkboard with LaTeX and Markdown Support
Thanks! I am aware of LyX and I did try it earlier but I did not quite like its ergonomics. I guess I prefer non-WYSIWYG tools more than the WYSIWYG ones. Another thing I wanted from my tool is that after a book club meeting is over, I should be able to share the same board in a distributable format (a simple HTML that self-renders it as Muboard), so that the participants can later refer to the same snippets that we went through during the meeting.
I have explained some of the reasons behind writing this tool here: https://github.com/susam/muboard#why (see section "Why?").
Here are a few examples of what the distributable board files look like: https://antmeet.github.io/boards/ .

Show HN: Poulette – A Color Palette GUI
Really cool!
So it looks like you're combining Delauny triangulation for the points with linear interpolation along the created triangles using Barycentric coordinates? Did I get that right? Pretty elegant solution (not to mention all the other little details that went into designing the interface).
It still looks a bit strange along the edges sometimes, and glancing at the source code it seems like you're mixing in linear RGB[0] so it's not that. I guess that just means that I'm looking at a saddle point in the color space?
(this made me wonder how smoothing functions would work for triangle meshes (that aren't secretly quads split into two triangles), and a quick search suggests that could be quite a deep rabbit hole to fall into)
