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.

Ask HN: Tell us about your project that's not done yet but you want feedback on
I'm working on Knowii [0], an Open Source (AGPL) Knowledge Management platform for communities. In the first version, communities will be able to curate/capture/share collections of useful/interesting resources. A browser extension will make it easy to capture information/links.
Later on, we'll add job boards, ways to share summaries/notes, news, vote, tag, explore through user profiles, etc.

Ask HN: Tell us about your project that's not done yet but you want feedback on
https://github.com/ambrosiogabe/MathAnimation
If you’ve ever tried to make a mathematical animation (think 3Blue1Brown), it’s a real pain. I was using manim for awhile to make animations for my YT channel, but the whole iteration process felt very slow and repetitive. So I thought I would recreate manim over the weekend, except with a GUI and real-time feedback. It’s been a year and a half and I’m hoping this weekend will be done soon so I can move on and start making videos again.
So far, it does a lot, but it still needs a lot of polish and refinement. The readme gives some gifs and a better idea of the feature set right now.

The Worst API Ever Made
Win32 definitely has some stinkers. But, video encoding APIs definitely take the cake for me. I've only tried a couple of FFmpeg's APIs and AV1's API, but my God, these are the worst API's I've ever had to deal with.
Just as an example, all I wanted was an API like this[0] for FFmpeg. In order to implement that API (which in my opinion is reasonable), I had to write this monstrosity[1]. It took me a solid week to find an example of how to do this, then another few days of fiddling until I finally just barely got something working. Then I threw in the towel even though the performance was horrible. I tried again a year later and spent another month wrestling with AV1 :/
The amount of leakage going on in these APIs is absolutely insane. I shouldn't have to know the intimate details of how video encoding works to use your library. If I do, then I may as well write my own encoder at that point.

Show HN: Mafs – React components for interactive math
I just so happen to be working on a real-time Gui first replacement for manim :)
It still has a ways to go, but I was able to create one video with it so far and I'm working on all the pain points I ran into while using it. Feel free to check it out if you're interested!

Ask HN: Who is using C++ as the main language for new project?
I'm using C++ for a minecraft clone that I've been tinkering on for the past year[0]. I also plan on using embedded lua for scripting, and I'm using RML UI for game HUDs, ImGui for development tools, and OpenGL for graphics. I use premake for my build system but plan on switching to CMake.
I'm also using it for an animation tool[1]. I've been using 3Blue1Brown's Manim (written in Python) which is amazing, but it lacks real-time editing and proper 3D blending. It also lacks audio synchronization, 3D texture support, and some more complex features that I'd like to add :)
