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.

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

How is Elliptic Curve Cryptography Encryption Fast?
I have a small write-up on various details of elliptic curve crypto implementation here: https://github.com/mratsim/constantine/tree/master/constantine/elliptic

My favourite Git commit (2019)
Not completely on topic (if you read TFA) but my favorite Git commit is by compiler badass and HN frequenter, where he checks in an entire C compiler to the D language repo:
https://github.com/dlang/dmd/pull/12507

The C Bounded Model Checker: Criminally Underused
A new generated code alone is 4000 lines long [1]. The actual code added is just 2000 lines, and some are used to pay debts, I mean, to make a proper code generator (which can be alternatively written in a simpler scripting langauge). In any case it is never comparable to the entier C parser proper.

OpenD, a D language fork that is open to your contributions
D is completely opensource already (https://github.com/dlang/dmd). The "open" of OpenD is just ADR saying that OpenD will be more open to new language features than D has historically been.

The OpenD Programming Language (fork of D)
The reference compiler, DMD, is open source: https://github.com/dlang/dmd
But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md
However, by some accounts, it's really hard to get anything through.
Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.
