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: Do you use an optimization solver? Which one? Why? Do you like it?
I use Minizinc in a personal toy project (https://gitlab.com/dustin-space/meal-scheduler), and GECODE or Google's ortools solver at the backend. It's used for meal planning. Unfortunately it's way way slower than I'd hope. I suspect I just have the domain not modeled efficiently. Maybe if I had a few days to put into it, and learn how to properly debug the CSP solver step by step, it might help...

What is your “I don't care if this succeeds” project?
That sounds like a fun application, both the usage and the implementation.
I wonder if you have any interesting example data-files that could be used with the model, preferable both something small and something larger? Would be fun to test the model locally to see how it behaves.
Notes: I'm assuming here that https://gitlab.com/dustin-space/meal-scheduler/-/blob/master... is the model used.

Anything you wish there was an open source solution for?
Try looking for something built around Optaplanner - basically taking the end game of rostering and working backwards.

Seeking Advice and Collaboration for an Open-Source Worker Cooperative Platform Project
OptaPlanner takes some of the items tracked in tool like Odoo and creates plans based on them. I.E. how do you manage shifts while juggling multiple constraints (Jerry can only work weekends, Jeff can only work afternoons, Jim can work weekends but only on double time, etc.)

[Combinatorial Optimization] What is a good algorithm, or genre of algorithms that I should read up on for an optimization problem with a set of sets, where at least one element of each set is required?
There is a library out there called Optaplanner that is designed for optimization of NP complete problems. It is hard to tell if that is exactly what this is, but I think you should be able to use this regardless.

Searching for something to schedule IT helpdesk shifts
Just stumbled upon https://www.optaplanner.org. Looks very interesting but also really overkill.

Self-hosted schedulers?
I've never used it but it sounds like OptaPlanner may be a scheduler in the same vein?
