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.

3 one-person million dollar online businesses
Sidekiq https://sidekiq.org/: This one started as an open source project, once it got enough traction, the developer made a premium version of it, and makes money by selling licenses to businesses.

Choose Postgres Queue Technology
Sidekiq will drop in-progress jobs when a worker crashes. Sidekiq Pro can recover those jobs but with a large delay. Sidekiq is excellent overall but it’s not suitable for processing critical jobs with a low latency guarantee.

We built the fastest CI in the world. It failed
> I'm not sure feature withholding has traditionally worked out well in the developer space.
I think it's worked out well for Sidekiq (https://sidekiq.org). I really like their model of layering valuable features between the OSS / Pro / Enterprise licenses.

Exploring concurrent rate limiters, mutexes, semaphores
I was studying Sidekiq's page on rate limiters. The first type of rate limiting mentioned is the concurrent limiter: only n tasks are allowed to run at any point in time. Note that this is independent of time units (e.g. per second), or how long they take to run. The only limitation is the number of concurrent tasks/requests.

Sidekiq and managing resumable jobs?
Uses Sidekiq's "fake" testing mode which will allow you to run the jobs explicitly

Organize Business Logic in Your Ruby on Rails Application
The code above isn't idempotent. If you run it twice, it will create two copies, which is probably not what you intended. Why is this important? Because most backend job processors like Sidekiq don't make any guarantees that your jobs will run exactly once.
There are several workarounds for this, like the magnificent Acidic Job gem or Sidekiq Pro/Enterprise features around enhanced reliability and unique jobs. Still, if they occur, bugs related to missing jobs and/or job idempotency are hard to track down and even harder to fix.

Where can I learn to deliver a proper solution?
I forgot to mention that reading code is also a good way to learn how to write code, it's like inspiration. Check repos of some gems you like. For example sidekiq https://github.com/sidekiq/sidekiq/tree/main/lib/sidekiq Or minitest https://github.com/minitest/minitest/tree/master/lib/minitest
