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.

Should I abandon using haskell for my compiler?
Comparing the haskell and cpp implementations of the LLVM tutorial lead me to believe it might be faster to learn haskell and implement the compiler in haskell than to implement it in cpp.

What would be your programming language of choice to implement a JIT compiler ?
I think for writing compilers Haskell deserves to make the list. It is really excellent at creating DSLs. https://www.stephendiehl.com/llvm/

Proposal to Merge Pyston with Cpython
I'm no expert, but you might be interested in: https://llvm.org/docs/tutorial/
There's also a Haskell version if you'd prefer: https://www.stephendiehl.com/llvm/
Idk how to do this in python as I'm not really good with it, but in C, to make your compiler a JIT, you would `mmap` a region as writeable, write the machine code to it that you already know how to generate, `mprotect` it as PROT_EXEC instead of PROC_WRITE, cast the pointer to the region to a function pointer, and then call it. These functions may be available in the python sys package but I don't really know.
I've implemented a "JIT" that takes machine code as hex and does this. Warning: it's complete garbage with no error checking but is a good proof of concept. https://gist.github.com/martinjacobd/3ee56f3c7b7ce621034ec3e...

Implementing a LLVM Micro C compiler in Haskell
This is amazing. I tried following Stephen Diehl's JIT compiler in LLVM tutorial[0] a few years ago but it was already outdated (the llvm-hs library changed quite a bit), and subsequent web searches didn't turn up much.
For those interested in tutorials like this, I'd also recommend a very literate Haskell compiler for the PCF language to C[1], which is essentially lambda calculus with some primitives.

Need some help with monad transformers
I'm currently working with llvm-hs-pure and am struggling to properly emit code for a module. I basically followed https://www.stephendiehl.com/llvm/#chapter-3-code-generation and have types like:

Can you make your own JavaScript by implementing ECMAScript standard?
You also wouldn't really be creating your own new programing language. You would be creating something that can run JavaScript by following JavaScript standards and syntax. You might be able to add some non-standard features of your own on top of those standards, or include your own standard library of helpers or utilities, but you can't completely make a new or alternative language and then load it in the browser (or at least not by reimplementing ECMAScript standards... you actually can make your own language that runs within any Javascript enviroment, if you provide an interpreter or compiler that transforms it into valid JS. Some people have done something like this, eg Elm: https://elm-lang.org/).

What is the best way to present the user the results of Haskell computations?
You should at least have a look at https://elm-lang.org/ it is a pure functional language like Haskell (although with fewer fancy syntax/type classes) but it has some lovely libraries for visualisation and even with plain elm (+ elm-ui) doing string transformations can be easily done.

Building React Components Using Unions in TypeScript
I get it. However, the whole point of using Unions to narrow your types, ensure only a set of possible scenarios can occur, and only access data of a particular union when it’s safe to do so. That’s some of what pattern matching can provide, and 100% of what using switch statements in TypeScript with their Discriminated Unions can provide. Yes, it’s not 100% exhaustive, but TypeScript is not soundly typed, and even Elm which is still has the same issue TypeScript does: You’re running in JavaScript where anything is possible. So it’s good enough to build with and much better than what you had.

How to render a basic calendar UI in Elm
The beauty of a language like Elm (and other lambda-calculus / functional programming inspired languages) is that there's very little transformation involved in going from an idea to code. And that seems to have a big impact on getting things done.

Is it possible to write games like Pac-Man in a functional language?
I think the most fun and approachable way for beginners to build games with functional programming is with Elm [1].
See a few (small, demo) games built by the community in [2] .
Notice Elm has abandoned the FRP approach in favor of Model-View-Update [3].
