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: Have you created programs for only your personal use?
In this way I estimate I create about 32 new programs a day for only my own personal use. But in many cases I only use each one once. ^R makes it easy to use them again a few times, but in other cases I save them into a shell script to make them easier to distribute to other machines, parameterize, and maintain. The one I most often use is probably a user interface for YouTube via youtube-dl or yt-dlp that consists of a few such shell scripts.
My main editor is Emacs. If I want to do the same thing repeatedly (e.g., delete a line containing the string .LVL) I create a keyboard macro with F3 and F4 (or C-x ( and C-x )) when I do it once, then run it repeatedly with C-x e. I probably write about 4 programs a day in this way.
Emacs has a M-: command to evaluate Lisp expressions, which are programs. Recent programs I have written in this way include (/ 43.2 1.7), (* 9.3 1.2), and (+ 8 3 2.50 3.50 3 7 3.50 3 1.50 4.50 6 5.50 6.50 6 3 2.50 2.50). Probably I write about 1 program a day in this way but I only use each one once. Longer Lisp programs like this can be written in scratch and executed with C-j or in .emacs (or .emacs.d/init.el) and executed with C-x C-e. For example, (global-set-key [f5] 'recompile). I use my .emacs file constantly every day but probably only add something to it about once a month. An outdated version is at https://github.com/kragen/kragen-.emacs.d/blob/master/init.e....
Sometimes I write bigger programs for my own personal use too.
A few years ago I wrote https://github.com/kragen/pytebeat for a livecoding performance of bytebeat in a bar. I finished writing it in the train on the way to the bar.
In https://github.com/kragen/laserboot I wrote a simple parametric 2-D CAD system for laser cutters in PostScript.
For Dercuano http://canonical.org/~kragen/dercuano I wrote a kind of shitty HTML rendering engine that generates a PDF file, as well as a simple CMS for generating a tree of HTML files from a directory of Markdown.
The other night I wrote a bytecode interpreter with a graphical display in C as a sort of mockup for the operating system of a small computer I recently got the parts for; it's in http://canonical.org/~kragen/sw/erika.git.
I've also written compilers, interpreters, ray tracers, database engines, parser generators, graphics libraries, logic circuit optimizers, 2-D game engines, etc., for my own use. Some of the recent ones are in http://canonical.org/~kragen/sw/dev3.

Ask HN: Have you created programs for only your personal use?
Plenty.
Of the ones I use every day:
* Parallel downloader (https://github.com/ThomasHabets/rslurp)

Ask HN: What are some tools / libraries you built yourself?
Also became a fun learning experience about terminals.
https://github.com/ThomasHabets/cmdg
I wanted to use GMail from a fast cli that used the native gmail API.
https://github.com/ThomasHabets/rslurp
I wanted to download concurrently and according to patterns. Ok, so honestly this one probably exists somewhere in a form that I would like, but I couldn't find it.
https://github.com/ThomasHabets/sim
I wanted multi-party authorization for sudo, and couldn't find one.
https://github.com/ThomasHabets/monotonic_clock
People kept using gettimeofday, so this is part of my compaign against it. (see https://blog.habets.se/2010/09/gettimeofday-should-never-be-...)
https://github.com/ThomasHabets/gtping
I worked in mobile core networks, and wanted a "ping" that used the GTP protocol since that won't be firewalled.
https://github.com/ThomasHabets/ind
I wanted my bash scripts to have automatic indentation, while not sacrificing buffering latency and such.
https://github.com/ThomasHabets/tlscheck
I wanted a simple tool to audit my TLS certificates for expiry.
https://github.com/google/huproxy
I was travelling to China on vacation and wanted a VPN out that would be unlikely to be blocked by the great firewall. Ok, so there are many VPN-like tools for getting through the GFW. Maybe it was just an excuse for me to write it. Honestly ssh -D would have likely worked just fine. It's being used by the keymaster project now though, so maybe it did something right: https://github.com/Cloud-Foundations/keymaster/blob/master/d...
https://github.com/google/tcpauth
I wanted to lock down SSH to anyone who doesn't have a secret key (and portknocking is usually ridiculous). Why not use TCP MD5 for it? https://github.com/google/tcpauth
