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.

The dangers of single line regular expressions
`$` does mean end of input in Java, unless you explicitly ask for multiline mode. In the latter case it means `(?=$|\n)` if also in Unix-lines mode, and the horrible `(?=$|(?I wrote a compiler from Java regex to JavaScript RegExp, in which you'll find that particular compilation scheme [1].

Rust on Espressif chips – 2023 Roadmap
> Scala choices were directly dictated by JVM
Initially, yes. But Scala has evolved beyond the JVM, with Scala.js [1] being rock-solid, and Scala Native [2] under development. Neither are truly hampered by the initial JVM roots of Scala.
> Scala gives you a better horse
Weird analogy ;)

Looking for an alternative to Javascript
Have you had a look at Scala.js yet? Also see "Scala.js for JavaScript developers." and "Tour of Scala."

Contrary to popular belief, Scala is actually a quite small and simple language
What does that have to do with language size? It also compiles to js https://www.scala-js.org/ and native https://scala-native.org/en/stable/

Switch JS job for Scala internship?
Here's a hybrid option: Scala.js. Yes, it is about building web applications but in Scala. You can retain the HTML/CSS/JS knowledge you have but build web applications from a typesafe and powerful language: Scala

Dropping Scala 2.11 support in Scala.js and Scala Native
The compiler crash in question affects another feature that we would like to merge for the benefit of all users, namely https://github.com/scala-js/scala-js/pull/4735. Keeping 2.11 means that testing and shipping that feature is much more difficult, even for 2.12+ users only. It's not just "to fix a compiler crash".

Windows decide whether your computer has limited or full Internet access
TS is more in the "mixed feelings" department, imho.
I would take Scala.js anytime instead. (If I would need to do front-end ever again).

Tmux, NeoVim, etc. to write pure Kotlin code?
You might want to look at Scala, they have proper LSP support with metals which means you can write your code in vscode, neovim, emacs, or even fleet (the new jetbrains text editor).

New plugin to support LSP file operations
Please write in the comments if you know of any language servers I should test it with. Currently I tested only metals and rust-analyzer.
-
Why are all the guides on using LSP functionality full of bloat?
If you are using nvim-lspconfig you can pass the settings as a Lua table to the setup function. For example, here are may metals settings:
- Type-Signature.com

What is the one thing you need everyday to make your job easier?
Bazel support in Metals. I didn't spend all that time figuring out and adjusting Emacs/Spacemacs and making my workflow (almost) mouse-free just to scrap my config and switch to IDEA's rodent infested ways.

Scala 2.13.9 is here
There is one small issue involving code completion returning inappropriate completions in some cases; https://github.com/scalameta/metals/pull/4414 will fix it, once it's included in a release. Perhaps that's the PR you saw?

Scala Isn't Fun Anymore
It is, by quite a bit.
While the "Scala IDE" project is dead for all practical purposes, IntelliJ IDEA's Scala plugin is actually pretty amazing. There's also a VisualStudio plugin that does pretty much the same and is advancing by leaps and bounds. There are also interconnecting projects that provide i.e. language server or build server that are reused by other projects. It's pretty modular. Metals (https://scalameta.org/metals/) is amazing.
In general the language has become a wee bit faster to build, there was good progress with build times during the 2.12/2.13 cycles.
With Scala3 the language got a bit simpler; concepts that were implemented explicitly using (hehe) implicits got their own keywords and a lot of the opinionated boilercode that cause a lot of debates is now generated during complication and hidden. A lot of "standardization" has occurred.

Starting with Scala: editor and version choice?
IntelliJ has its own BSP. The other one is Metals. You can use it with many IDEs (vim, emacs, vscode, atom,...). Use it with emacs if you're comfortable with it.
