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.

Is Something Bugging You?
Along similar lines, Mario Carneiro wrote a formalisation of a subset of x86 in MetaMath Zero (https://github.com/digama0/mm0/blob/master/examples/x86.mm0) with the ultimate goal of proving that the MetaMath Zero verifier itself is sound. https://arxiv.org/pdf/1910.10703.pdf
(And of course Permutation City is a fiction book all about emulating computers with sound properties!)

Is it possible to make concrete progress on the alignment problem using an abstract theory of formal control of computer systems? Any help or advice would be really appreciated.
For the first part I have no idea but for the second part I feel like one workable approach is formal control of computer systems. For instance we have a lot of formal mathematical systems (metamath, lean, coq, isabelle etc) and there are attempts to model computer architectures in these systems (there's a cambridge group working on a formalised version of the ARM architecture, and I know Mario Carneiro is working on MM0 which I think has formalised x86) which is all cool.

Category theory is a universal modeling language
Perhaps look into Metamath Zero / mm0 which.. well I'll just quote from the project [1]:
> Metamath Zero is a language for writing specifications and proofs. Its emphasis is on balancing simplicity of verification and human readability of the specification. That is, it should be easy to see what exactly is the meaning of a proven theorem, but at the same time the language is as pared down as possible to minimize the number of complications in potential verifiers.
> The goal of this project is to build a formally verified (in MM0) verifier for MM0, down to the hardware, to build a strong trust base on which to build verifiers.

The State of State Machines
IMO an interesting project in this space is: mm0 / MetaMath Zero - Closing the loop in proof verification down to verifying the machine code of the verifier. Goes from first-order logic to peano arithmetic to a model of x86 to a model of the verifier written in x86. Interestingly, it demonstrates that verification of a compact proof can be performed in linear time (!) if the proof is structured correctly. -- https://github.com/digama0/mm0
The fact that proof checking can take linear time (though not proof-finding), and the fact that it incorporates so many 'layers' has emboldened my opinion that such a thing as I described above is possible and has a enormous potential.

Ask HN: What are some unpopular technologies you wish people knew more about?
(1) Zulip Chat - https://zulip.com/ - seems to be reasonably popular, but more people should know about it
I’ve been using it for over 5 years now [1], and it’s as good as ever. It’s way faster than any other chat app I’ve used. It has a good UI and conversation model. It has a simple and functional API that lets me curl threads and write blog posts based on them.
(only problem is that I Ctrl-+ in my browser to make the font bigger – I think it’s too dense for most people)
(2) re2c regex to state machine compiler - https://re2c.org
A gem from the 90’s, which people have done a great job maintaining and improving (getting Go and Rust target support in the last few years). I started using it in 2016, and used for a new program a few months ago. I came to the conclusion that it should have been built into C, because C has shitty string processing – and Ken Thompson both invented C AND brought regular languages to computing !!
In comparison, treesitter lexers are very low level, fiddly, and error prone. I recently saw dozens of ad hoc fixes to the tree-sitter-bash lexer, which is unsurprising if you look at the structure of the code (manually crawling through backslashes and braces in C).
https://github.com/tree-sitter/tree-sitter-bash/blob/master/...
These fixes are definitely appreciated, but I think it indicates a problem with the model itself.

Debate Land Beta 0.2 is out!
A few more truly in the vibe of open source projects not advertising their hosting providers: https://plane.so/ , https://element.io/ , https://www.loomio.com/ , https://zulip.com/ , and it keeps going... Very few open source projects, in the FOSS sense, are advertising their hosting provider.

All Your Licensing Are Belong to Us^W You
I was so excited to see this happen!
I'm not a customer of yours, but your blog posts inspired me a lot. Your journey through quitting caffeine is a great and heartening read.
I've got two things to say;
1) Will you consider source-availabling the web portal (app.keygen.sh) too? Some enterprises could use it for easy management/support for custoner's licenses. Although now that I think about it, it could also discourage custom, more suitable implementations for each use-case... I'm torn on this one. I would like to see it available on GitHub too just out of curiosity too. It's very beautiful.
2) For a team + customers' chat, I cannot recommend Zulip enough. It's a joy to use and has the most innovative chat system I've ever seen. https://zulip.com
I hope your business keeps prospering!
