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: How to quickly animate sketches and 2D diagrams?
I'm using Mermaid, Excalidraw and PlantUML diagrams to explain and document what I'm working on and they work great and are a lot better than screens of prose, but I've become aware that something is missing: motion.
Animation brings a whole lot more to explanations, making simple explanations of how request coalescing works easy to understand, token simulations [0] through to helping explain concepts like Fresnel lenses [1]. Embedding them into GitHub READMEs, tweets and documentation would be awesome.
I found Excalidraw Claymate [2] but the stop motion approach with no tweening support makes it painful to create animations where circles move from place to place. There's also Manim [3] but I think this is more for maths.
Adobe Flash used to be the go-to; what do you reach for when you want to illustrate a concept with an animated diagram?

Stately Editor Public Beta
Nice work! Anything that helps visualise state I'm happy to see.
Reading the linked article I'm unclear: does Stately generate output that we run with XState? Or is it a SaaS where we design and run the state machine (a bit like Camunda provides for running BPMN diagrams)?
If not already present, a visual runner would be awesome - like https://github.com/bpmn-io/bpmn-js-token-simulation allows, to explore the state.

Text-to-CAD: Risks and Opportunities
https://github.com/gumyr/build123d :
> Build123d is a python-based, parametric, boundary representation (BREP) modeling framework for 2D and 3D CAD. It's built on the Open Cascade geometric kernel and allows for the creation of complex models using a simple and intuitive python syntax. Build123d can be used to create models for 3D printing, CNC machining, laser cutting, and other manufacturing processes. Models can be exported to a wide variety of popular CAD tools such as FreeCAD and SolidWorks.
> Build123d could be considered as an evolution of CadQuery where the somewhat restrictive Fluent API (method chaining) is replaced with stateful context managers* - e.g. with blocks - thus enabling the full python toolbox: for loops, references to objects, object sorting and filtering, etc.*

> This package is inspired by the NURBS-Python package, however uses a NumPy-based backend for better performance.
> Curve, and Surface are non-uniform non-rational B-Spline geometries (NUBS), RationalCurve, and RationalSurface are non-uniform rational B-Spline Geometries (NURBS). They all built upon the class BSpline. Coordinates have to be in 3D space (x, y, z)

Ask HN: What would you show an interviewer if they asked you for code samples?
A template language that I wrote for generating HTML. Meant to be included as a C++ library. https://github.com/Ghoti-io/Tang
Plenty of other C++ code of mine is on Github (such as a bunch of utility stuff, a thread pool, and a HTTP server that I'm writing from scratch), even though I would only call myself an intermediate C++ programmer. I just happen to like the language.
Or, if I had to throw other stuff into the mix, a fairly recent patch to Manim (Python) that got accepted (https://github.com/ManimCommunity/manim/pull/3155).
If I were really pressed, I would dig up a lot of my Drupal (PHP) stuff that I did years ago.
