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.

WASM_of_OCaml
Yes. Darklang was originally in OCaml using js_of_ocaml, and we ported it to F# using Blazor (https://github.com/darklang/dark/tree/main/backend/src/Wasm). It works.
We found that in dotnet 6, the code was much slower, with long startup times and a much bigger download, than in js_of_ocaml. It also had a lot of issues in running in a Webworker, which wasn't the case for js_of_ocaml.
In dotnet 7, the webworker issues are better and AOT is easier, so startup is faster. Download sizes are still bad, and it's still slower than js_of_ocaml.
However, dotnet allows almost any code to run in WASM, which js_of_ocaml had large limitations. This meant a decent chunk of functionality had to be worked around to make separate js vs native targets, which also was a massive pain and took a long time. Dune's virtual targets wasn't ready at the time - I think we were one of the test cases for it.

It's so unfortunate they decided to go with the Clojure/Haskell type syntax, as opposed to something friendlier like Elixir. A lot of people will not even try this language as a result. [Unison]
Why should I use this instead of https://darklang.com/

Cloud, Why So Difficult?
First it was probably Dark. They made a lot of noise some years ago, but then I never heard of them again (looking at their current website, looks like they moved on to AI now, obviously).

New open-source programming language for DevOps engineers by the creator of the CDK
Reminds me of Darklang. Personally, I don't think vendoring cloud services into a language is going to be beneficial. I'm curious how the language deals with vendor updates. Do I have to upgrade the language then? If so, I see a lot conflicts coming from this. Then it comes down to Javascript or HCL, the HCL bit makes me think that the below statement is not as truthy as it is on the surface:

Darklang Release 9
We still don't have all that many users (~100 active), so I'm not sure you'll find an answer here. But we collect that sort of feedback publicly, which might answer your question: https://github.com/darklang/dark/discussions/categories/feed...

Making Something Waspy: A Review Of Wasp
I wish I could remember what took me to YCombinator's website on the 10th of October, 2022. That was when I first heard about Wasp and another language called DarkLang. After I learned about Wasp, I was intrigued and curious to know how it works, which led me to join the discord server the next day.

The Current State of Infrastructure From Code
There are others in this space I did not assess like Encore, Shuttle, Modal, and Dark. These were not assessed for the sake of time. If you're interested in IfC, I encourage you to take a look at these others.

Finally, we have support for negative numbers!
Oh, finally! I was waiting to build my serverless CRUD webapp in Dark (OCaml + JavaScript and Fsharp?) until they had support for returning negative numbers on a GET request!

Linus Torvalds adds arbitrary tabs to kernel code
i want a diff tool that shows me exactly which tokens have changed, and which haven't, regardless of how they are laid out.
These already exist: https://github.com/Wilfred/difftastic
when we get that, then we should get even less merge conflicts.
Counterintuitively, that is not the case. AST-merge is a much, much, much, much, much harder problem than AST-diff.
https://github.com/Wilfred/difftastic?tab=readme-ov-file#can...
The fact that diffs can be used to drive a 3-way merge is in fact an accidental property that arises due to the sheer crudeness of the diff format. As soon as you start using more-sophisticated diff formats, solutions to "the diff problem" no longer lead directly to solutions to "the merge problem".

Difftastic, a structural diff tool that understands syntax
Yes there is an `—-override` option you can use to specify the language in which a file should be parsed.

Prettier $20k Bounty was Claimed
If you're looking for a VS Code extension or a GitHub app, check out https://semanticdiff.com/. I'm a co-founder of this project.
If you prefer a CLI tool, check out https://github.com/Wilfred/difftastic. It supports more languages, but doesn't recognize when code has been replaced by an equivalent version ("invariances"). So it will show some changes (e.g. replacing a character in a string with an escape sequence) even though they are technically equivalent.

Pijul: Version-Control Post-Git • Goto 2023
Shameless plug: I've written difftastic[1], a tool that builds ASTs and then does a structural diff of them. You can use it with git too.
It's an incredibly hard problem though, both from a computational complexity point of view, and trying to build a comprehensible UI once you've done the structural AST diff.

Always leave a trailing comma in Python lists, dicts, tuples
There is a diff tool called difftastic: https://github.com/Wilfred/difftastic
The idea is that it does not show diff based on text change, but on syntastic meaning. For that, it uses tree-sitter.
I think it still shows the trailing comma in the situation as shown in the article, but it's quite different experience than the standard text based diff.
What are some alternatives?
nvim-ts-rainbow - Rainbow parentheses for neovim using tree-sitter. Use https://sr.ht/~p00f/nvim-ts-rainbow instead
delta - A syntax-highlighting pager for git, diff, and grep output
Bracket-Pair-Colorizer-2 - Bracket Colorizer Extension for VSCode
diffsitter - A tree-sitter based AST difftool to get meaningful semantic diffs
unison - A friendly programming language from the future
neogit - An interactive and powerful Git interface for Neovim, inspired by Magit
nanos - A kernel designed to run one and only one application in a virtualized environment
Visual Studio Code - Visual Studio Code
liquibase - Main Liquibase Source
gumtree - An awesome code differencing tool
terraform-cdk - Define infrastructure resources using programming constructs and provision them using HashiCorp Terraform
tree-sitter-cpp - C++ grammar for tree-sitter
