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.

How do you generally go about finding the Jacobian of a complicated observation function for a Kalman filter?
To add to software for #1, look for packages that do forward-mode AD. For Jacobians (many outputs), forward-mode AD is often faster than back-propagation (reverse mode). I use ForwardDiff.jl which usually accepts any function the user might bass in as observation function https://github.com/baggepinnen/LowLevelParticleFilters.jl/blob/master/src/ekf.jl#L45 Here's a nice intro to forward and reverse mode ad https://github.com/MikeInnes/diff-zoo/blob/notebooks/backandforth.ipynb It's the second notebook in a series, might want to read the first as well if you find this topic interesting.

Ask HN: What are some examples of elegant software?
This is an obscure one, but Mike Innes "[automatic] differentiation for hackers" tutorial. It's a code tutorial, not software, if that counts. Both the way it's constructed and the functionality of Julia that gets shown off here.

- Neural networks with automatic differentiation.

Ask HN: Who's an open source maintainer/project that needs sponsorship or help?
Nexus: https://github.com/jfilby/nexus
This is a web framework + ORM for Nim. It's in desperate need of more work to support DBs other than PostgreSQL and make the ORM more flexible. The web side also needs more work.
- Ask HN: Should I learn more languages?
-
Ask HN: Companies of one, what is your tech stack?
I use it mainly for high-performance backend engines. E.g. I'm writing an automated trading system and the trading engine is written in Nim.
I wrote a Nim web framework that has an ORM: https://github.com/jfilby/nexus. However I mainly use the ORM with the back-end engines. You could write a Django-style web app with Nexus + Nimja, but it's difficult to compete with the huge ecosystems of React and Flutter.

Ask HN: What is the job market like, for niche languages (Nim, crystal)?
It's not good for Nim, unfortunately. The language is great, but the community isn't that big.
If you're looking for a web framework with an ORM for Nim, check out Nexus: https://github.com/jfilby/nexus

Building a personal blog using Django
Django is a great MVC framework. It might be overkill for a blog as another poster wrote, but it's still a good way to learn Django.
If you ever want to learn Nim, please consider Nexus (https://github.com/jfilby/nexus) as I'm building it to be something like Django for Nim.

Show HN: Nexus Development Framework
Nexus is a Nim development framework.
https://github.com/jfilby/nexus
The aim to create a web framework similar to Django, with a built-in ORM. The view layer needs work, and is mostly built out of available libraries with Jester for routing and Nimja for templating.

Ask HN: What are some examples of elegant software?
Nim. It's just so quick and easy to write high performance code. That's why I'm writing a web framework for it, soon to be released: https://github.com/jfilby/nexus
