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.

D Programming Language
D has a language server (LSP) you can use any IDE/editor that supports it
- Sublime Text
- vscode
- vim/nvim
- emacs
etc..

A beginner's guide to constant-time cryptography (2017)
Percival cache attacks on Hyperthreading.
I go over some examples here: https://github.com/mratsim/constantine/issues/358#issuecomme...

D Programming Language
`when myCondition():` instead of `if myCondition:` is done at compile-time.
Alternatively you can use a `static:` code block to force compile time evaluation. Or tag a function {.compileTime.} or tag function inputs with `static` modifier.
It is possible to create a compiler or an assembler running fully in Nim macros as well:
- https://github.com/mratsim/constantine/blob/master/constanti... (all that file runs at compile-time)
You can also implement Continuation-Passing-Style transformation at compile-time:
- Fast constant-time pairing or elliptic curve based cryptography (Nim/C)

Matrix Multiplication Using Only Addition
At a glance this sounds like a re-discovery of addition chains and using them to construct Pippenger algorithm. But applied to matrices instead of group elements.
See: https://github.com/mratsim/constantine/issues/37

Elliptic Curve Cryptography Explained
I usually explain extension fields as similar to complex numbers with regards to reals.
I've collected a lot of extension fields references while working on my own implementation: https://github.com/mratsim/constantine/tree/master/constanti...
The best likely being
- Arithmetic of Finite Fields
- Constant-Time Big Numbers: An Introduction
-
just a question that has been lingering on my mind
Regarding your first question, you don't need to attack the hard-drive, for non constant-time crypto you can read power consumption or electromagnetic traces when the secret key is used to reconstruct it: - https://github.com/mratsim/constantine/wiki/Constant-time-arithmetics

DSL for Zero Knowledge Proofs
KZG for sure yes, I actually already started implementing them: https://github.com/mratsim/constantine/tree/c2d716b/research/kzg_poly_commit
