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.

Eliezer Yudkowsky has great news: "Parents conceiving today may have a fair chance of their kids living to see kindergarten."
As a developer of a proof assistant (Kind) I'm highly interested in this line of work. Can you point me to some of these papers? And perhaps people involved in this line of work?

How to handle list / contiguous array definition and implementation in a type system?
I have seen in languages like KindLang the definition of Array be like a Binary tree, but there is some magic there in the definition of the Array type that I don't understand yet. Also, I don't want to define the contiguous array further., it should be a literal contiguous array. The Kind "Word" type definition (arbitrary number of bytes) is closer to my contiguous array, but it has a similarly complex definition which like I said I don't understand.

Type Checking as Calculation
Totally agree about the Blub Paradox, but there's definitely value in Self Types. See, for example, [Kind](https://github.com/Kindelia/Kind), which is able to type recursive data types by using Self Types.

Please, keep in mind there is ZERO FUNDING for my projects.
For these who don't know, I'm the author of Kind and HVM. I've recently seen a criticism from an influent person in the community, who I often took as an inspiration, that made me really sad. "the guy behind this has built some impressive-sounding stuff before... it looks like his projects tend to just... go nowhere and he just abandons them and does something else?"
-
Is it possible to make join work for arbitrary depths?
This is very easy with dependent types! For example, in Kind:
- A massively parallel, optimal functional runtime in Rust
- Eu acabei de lançar um dos "compiladores" mais rápidos do mundo. Apoiem o trabalho brasileiro!

Why do lifetimes need to be leaky?
Correctness prover which uses lifetimes (Polonius).

Databases are the endgame for data-oriented design
And, well, polonius (Rust borrow checker magic) I believe is built on datalog-ish concepts: https://github.com/rust-lang/polonius

Why doesn't rust-analyzer reuse infrastructures of rustc?
There is also polonius (https://github.com/rust-lang/polonius) which should replace the borrow checker but does not receive a lot of development resources.

Rust front-end merged in GCC trunk
This is eventually going to be a feature-complete compiler, targeting a specific rustc version. I believe the plan is to use polonius [1], presumably as an "optional" feature so they can build a stage 1 without it, use that to build polonius, then build the final compiler with it included.

E.g. there you may just stop using current borrow-checker and switch to Polonius.

What are Rust’s biggest weaknesses?
The borrow checker is too dumb (https://github.com/rust-lang/polonius) fixes a lot of this.

Datafrog: A lightweight Datalog engine in Rust
It looks like an official borrow checker implementation called Polonius uses it as a dependency, so it makes sense: https://github.com/rust-lang/polonius/blob/981785c101b68ff54...

Differential Datalog: a programming language for incremental computation
If you click around a little, you end up on a blog post with this tidbit:
> This project got put together rather suddenly, in response to some work the Rust folks are doing[1] on their new and improved borrow checker.
I don't think I could tell you more than "Frank wrote it to help rust folks who were previously doing work with differential-dataflow directly."

Generic associated types to be stable in Rust 1.65
Good news is that there's also works going on to relax the restrictions, like polonius. But it seems that it still have a long way to go before it can land in stable Rust...

Rust for Linux officially merged
GCC-rs isn't intended for bootstrapping, it is intended to be an actual fully featured Rust compiler in the future, mrustc is a Rust compiler intended for bootstrapping though. GCC-rs is still very early targeting an older version of the reference compiler without things like a borrow checker, but that's not going to be the case forever. The GCC-rs folks have expressed interest in re-using the borrow checker library used by the reference compiler called polonius enabling them to relatively easily add borrow checking.
