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.

Dyalog APL Keyboard Layouts
Should you wish to type them on a normal keyboard:
https://abrudz.github.io/lb/apl has a browser bookmarklet which adds an APL language bar to the top of any web page so you can type in any input box with backtick prefixes.
https://github.com/abrudz/Kbd has a Windows Input Method Editor (IME) that adds system-wide RightAlt+letter combos.

Ask HN: Do I need a special keyboard layout to learn array programming?

APL has the highest percentage of trans programmers for the 2nd year in a row, according to Stack Overflow survey
I use setxkbmap -layout us,apl -variant ,dyalog -option grp:switch on Linux and https://github.com/abrudz/Kbd on Windows.

Ngn/k (free K implementation)
This might have been true a couple of years ago but it is totally untrue now.
I'm not sure why you couldn't use the student version of Dyalog? Sounds like it would have been fine. There are also many more FOSS implementations of array languages now, such as ngn/k and April. https://github.com/phantomics/april
'only available for Linux' - not true https://github.com/abrudz/Kbd/ and others (also different input modes like `w for ⍵)
'no community support' - on the contrary there is a big and helpful APL community https://aplwiki.com/wiki/Chat_rooms_and_forums that is (imo) more useful than stackoverflow
'Dynamic scoping...' - Dyalog's (and other APL's) dfns have lexical scope.
'The language is extremely terse' - is this meant to be a bad thing?
'The code tends to be very hacky' - maybe if you write bad code or try and write C in APL (it won't work)
- Use TAB entry style in Dyalog for Mac?

Learning APL
In general programming I like to use a keyboard layout which allows typing APL glyphs with Right Alt: https://github.com/abrudz/Kbd

Ngn/k (free K implementation)
- No debugging at all. You run the code and pray for the best.
A year after we started my classmate decided to drop the project since he felt he couldn't keep up with the complexity: each line of code was non-trivial and really hard to understand.
Eventually we had to rewrite the whole project because GNUs interpreter didn't support big integers, and trying to circumvent that resulted in very poor performance. The new version was written in Julia (https://github.com/emlautarom1/Julia_Simulator), so we were able to reuse a lot of "array code". The project got cancelled in the middle of the rewrite and we kind of forgot about it.
What are some alternatives?
BQN - An APL-like programming language. Self-hosted!
kona - Open-source implementation of the K programming language
kalamine - Keyboard Layout Maker
PDP_11_Simulator - PDP11 Simulator written in APL

kerf1 - Kerf (Kerf1) is a columnar tick database and time-series language for Linux/OSX/BSD/iOS/Android. It is written in C and natively speaks JSON and SQL. Kerf can be used for trading platforms, feedhandlers, low-latency networking, high-volume analysis of realtime and historical data, logfile processing, and more.
