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.

Serverless Horrors
Reading the GitHub issue about this is somewhat entertaining: https://github.com/docker/for-linux/issues/690
People are getting hacked a lot because of this, and docker doesn't seem to care all that much.

What could go wrong with docker containers?
Sure - I work in an environment where I have to be on the VPN to access Snowflake. I also have to use Windows. The easiest dev environment for that is to install WSL2 and do the development in Ubuntu therein. However, the way that WSL2 manages Ubuntu is through some Windows host processes instead of the daemons that typically are used when you run Ubuntu. You can search around and find various reports about this - it manifests as "Cannot connect to the docker daemon." Here is one example from a quick search. On Windows, the way that you can easily get around that, if your org supports it, is to run Docker Desktop for Windows, which then manages that daemon process. That's all fine and good, but WSL has issues with routing traffic through VPNs for some reason. Again, here is a quick example of the type of things you'll find when you Google about this problem.

Network Adapter Restriction, Possible?
For a more universal configuration, setting the ip option in Docker's daemon.json file should tell Docker to only bind to that IP address. It does sound like there may be some bugs with this setting though, so your mileage may vary.

MEM USAGE 0 - using sudo docker stats
Thank you. Your link is probably solution, it looks similar to the post I found before on github (and I was afraid to use it).

Making Code Faster
> The other two languages I’ve used mostly in recent decades are Java and Ruby and the profiler situation is for both those languages is kind of shitty. I had to pay real money to get the Java profiler I used at AWS and while it worked, it was klunky, not fun to use.
These days, async profiler (https://github.com/jvm-profiling-tools/async-profiler) is much better than the Go tooling for performance. It is a joy to use and features a top-like view for the hottest methods. It works for locks, allocations and CPU time. It also integrates with JMH.

Why would a Java prime sieve run at only half its speed _some_ of the times?
Also, running it under a profiler (I recommend async-profiler[1]) should give you a good idea of where the slowdown occurs which might help you pin it down further.

Profile it. async-profiler is really great. Alternatively you can check out VisualVM/JProfiler/YourKit
