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.

GNU/Hurd strikes back: How to use the legendary OS in a (somewhat) practical way
Even in the noncommercial world, Hurd's gone precisely nowhere. RedoxOS is a toy and had a GUI within a year or so. Brutal got in within two. SerenityOS not only built a GUI but the beginnings of the first greenfield web browser to gain any semblance of modern standards support in the past several decades. Honestly, what's Hurd doing wrong to flounder so hard?

Rust is ugly, doesnāt even let you write simple data structures, unsafe rust is not even defined, makes the simplest things so hard to write and did I mention itās ugly?
Ah yes, std, that famous crate that is unusable for systems programming. God forbid anyone do any "systems" programming that uses std.

The wild world of non-C operating systems
Looks like C++ to me!
And my point is that when you mention OS-es like Mezzano (3k stars on Github, a dozen contributors [1]) and Redox (13k stars, 80 contributors [2]), but don't mention Serenity (18k stars, over 100 contributors [3] (Github limits this view to the top 100)) it seems funny.

How far are we from writing Redox on Redox?
Side note, blog posts may have been quiet but there's still been some commit activity here and there.

Porting QEMU to RedoxOS
>I wish opportunities had been around when I was learning to program.
And yet now, we have plenty of projects and nobody contributing.
https://github.com/redox-os/redox/graphs/contributors
This graph doesn't look so healthy. Projects with one major contributor tend to die the moment that contributor loses interest.
Which leads me to wonder, if rust is so popular, and this is one of the most relevant rust projects in the wild, why is this essentially a single contributor repo? Linus didn't write Linux by himself. Redox is never going to happen with a single developer.
Doesn't anyone want a memory safe OS and micro kernel? What does this say about the demand for memory safe systems languages?

Pop!_OS uses a lot of Rust
I think the guy behind RedoxOS works for them.

Java 23: The New Features Are Officially Announced
Contrary to what vocal Kotlin advocates might believe, Kotlin only matters on Android, and that is thanks to Google pushing it no matter what.
https://spectrum.ieee.org/the-top-programming-languages-2023
https://snyk.io/reports/jvm-ecosystem-report-2021/
And even so, they had to conceed Android and Kotlin on their own, without the Java ecosystem aren't really much useful, thus ART is now updatable via Play Store, and currently supports OpenJDK 17 LTS on Android 12 and later devices.
As for your question regarding numbers, mostly Java 74.6%, C++ 13.7%, on the OpenJDK, other JVM implementations differ, e.g. GraalVM is mostly Java 91.8%, C 3.6%.

Apple releases Pkl ā onfiguration as code language
Pkl was built using the GraalVM Truffle framework. So it supports runtime compilation using Futurama Projections. We have been working with Apple on this for a while, and I am quite happy that we can finally read the sources!

Live Objects All the Way Down: Removing the Barriers Between Apps and VMs
That's pretty interesting. It's not as aggressive as Bee sounds, but the Espresso JVM is somewhat similar in concept. It's a full blown JVM written in Java with all the mod cons, which can either be compiled ahead of time down to memory-efficient native code giving something similar to a JVM written in C++, or run itself as a Java application on top of another JVM. In the latter mode it obviously doesn't achieve top-tier performance, but the advantage is you can easily hack on it using all the regular Java tools, including hotswapping using the debugger.
When run like this, the bytecode interpreter, runtime system and JIT compiler are all regular Java that can be debugged, edited, explored in the IDE, recompiled quickly and so on. Only the GC is provided by the host system. If you compile it to native code, the GC is also written in Java (with some special conventions to allow for convenient direct memory access).
What's most interesting is that Espresso isn't a direct translation of what a classical C++ VM would look like. It's built on the Truffle framework, so the code is extremely high level compared to traditional VM code. Details like how exactly transitions between the interpreter/compiled code happen, how you communicate pointer maps to the GC and so on are all abstracted away. You don't even have to invoke the JIT compiler manually, that's done for you too. The only code Espresso really needs is that which defines the semantics of the Java bytecode language and associated tools like the JDWP debugger protocol.
https://github.com/oracle/graal/tree/master/espresso
This design makes it easy to experiment with new VM features that would be too difficult or expensive to implement otherwise. For example it implements full hotswap capability that lets you arbitrarily redefine code and data on the fly. Espresso can also fully self-host recursively without limit, meaning you can achieve something like what's described in the paper by running Espresso on top of Espresso.

Quarkus 3.4 - Container-first Java Stack: Install with OpenJDK 21 and Create REST API
Quarkus is one of Java frameworks for microservices development and cloud-native deployment. It is developed as container-first stack and working with GraalVM and HotSpot virtual machines (VM).

Level-up your Java Debugging Skills with on-demand Debugging
Apologies, I didn't mean to imply DCEVM went poof, just that I was sad it didn't make it into OpenJDK so one need not do JDK silliness between the production one and the "debugging one" since my experience is that's an absolutely stellar way to produce Heisenbugs
And I'll be straight: Graal scares me 'cause Oracle but I just checked and it looks to the casual observer that it's straight-up GPLv2 now so maybe my fears need revisiting: https://github.com/oracle/graal/blob/vm-23.1.0/LICENSE
