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.

Fly.it Has GPUs Now
As far as I know, Fly uses Firecracker for their VMs. I've been following Firecracker for a while now (even using it in a project), and they don't support GPUs out of the box (and have no plan to support it [1]).
I'm curious to know how Fly figured their own GPU support with Firecracker. In the past they had some very detailed technical posts on how they achieved certain things, so I'm hoping we'll see one on their GPU support in the future!

MotorOS: a Rust-first operating system for x64 VMs
I pass through a GPU and USB hub to a VM running on a machine in the garage. An optical video cable and network compatible USB extender brings the interface to a different room making it my primary “desktop” computer (and an outdated laptop as a backup device). Doesn’t get more silent and cool than this. Another VM on the garage machine gets a bunch of hard drives passed through to it.
That said, hardware passthrough/VFIO is likely out of the current realistic scope for this project. VM boot times can be optimized if you never look for hardware to initialize in the first place. Though they are still likely initializing a network interface of some sort.
“MicroVM” seems to be a term used when as much as possible is stripped from a VM, such as with https://github.com/firecracker-microvm/firecracker

Virtual Machine as a Core Android Primitive
According to their own FAQ it is indeed: https://github.com/firecracker-microvm/firecracker/blob/main...

We Replaced Firecracker with QEMU
Dynamic memory management - Firecracker's RAM footprint starts low, but once a workload inside allocates RAM, Firecracker will never return it to the host system. After running several workloads inside, you end up with an idling VM that consumes 32 GB of RAM on the host, even though it doesn't need any of it.
Firecracker has a balloon device you can inflate (ie: acquire as much memory inside the VM as possible) and then deflate... returning the memory to the host.

Neverflow: Set of C macros that guard against buffer overflows
Very few things in those companies are being written in Rust, and half of those projects chose Rust around ideological reasons rather than technical, with plenty of 'unsafe' thrown in for performance reasons
https://github.com/firecracker-microvm/firecracker/search?q=...
The fact that 'unsafe' even exists in Rust means it's no better than C with some macros.
Don't get me wrong, Rust has it's place, like all the other languages that came about for various reasons, but it's not going to gain wide adoption.
Future of programming consists of 2 languages - something like C that has a small instruction set for adopting to new hardware, and something that is very high level, higher than Python with LLM in the background. Everything in the middle is fodder.

Do you use Rust in your professional career?
https://github.com/firecracker-microvm/firecracker is the one that comes to mind, but most of these are internal.
-
Rust is ugly, doesn’t 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 it’s ugly?
Ah yes, std, that famous crate that is unusable for systems programming. God forbid anyone do any "systems" programming that uses std.

I Don’t wanna use Docker or kubernetes
You can use Firecracker - the micro-virtualization framework and hypervisor written in rust! Never mind the 10x I/O slowdown.

Does anybody have a use-case for Scala WASM compilation target?
With the recent work AWS has done around snapshotting you can launch a VM in less than a second.

Boa JavaScript Engine v0.17 released
For example, we have implemented Hidden Classes (what we call Shapes) and constant folding. We are also looking into NaN boxing, Inline Caching, and a control flow graph construction, to implement optimisations such as dead-code elimination.
Yeah, pretty much. I'm not sure if we're gonna need to implement Static Shapes first but at least we need to make it possible to separate codeblocks from contexts for this to be feasible.

Official /r/rust "Who's Hiring" thread for job-seekers and job-offerers [Rust 1.67]
Hi, I'm looking for full time work and I'm interested in roles related to compilers, developer tools and systems. I'm a college senior(graduating on May, 2023) and have been working as an [IOS Developer](https://www.cyengagement.org/) for the past two years. At University, I took a compilers class where I learnt to use LLVM and MLIR to compile programs to various architectures. In Oct. 2022, I was selected to attend the [Programming Language Implementation Summer School](https://pliss.org/2022/) where I got to learn about compiler implementation and language tools from leading researchers around the world. Recently, I have been contributing to [Boa](https://github.com/boa-dev/boa), an embeddable Javascript engine written in Rust, by fixing issues and implementing features to improve conformance with ECMAScript specification. Aside from working on compilers, I have volunteered at conferences like ICFP'21 and PLDI'22 to familiarize myself with latest research in the field of compilers. You can find more information about me and my work in my [blog](https://veera.app) and Github [profile](https://github.com/veera-sivarajan). Thank you for your time and consideration.

Dune: A new JavaScript and TypeScript runtime built in Rust
I would be curious how much effort it would be to swap boa for V8 to have an all Rust runtime :) If it's not meant to be a production-ready project anyways.

Implementing a safe garbage collector in Rust
Although you probably could use it for something else, Boa[1] is a good demonstration of this (it uses the GC crate, but the same principle probably applies).

A python interpreter written in Rust?
Deno uses the V8 JavaScript engine, which is written in C/C++. There is a Rust JavaScript engine called Boa though.

Boa release v0.14: A JavaScript engine written in Rust
One of the big changes in this release was to port the whole execution of JavaScript to 2 steps, a compiler and a VM. You can find more information about the VM here: https://github.com/boa-dev/boa/blob/main/docs/vm.md

Rust Is the Future of JavaScript Infrastructure
Author here. A few other Rust projects to note that I didn't mention in the original post I've since found:
- Boa (JS engine in Rust) – https://github.com/boa-dev/boa
- RSLint (JS/TS linter in Rust) – https://github.com/rslint/rslint
- Node version manager in Rust – https://github.com/Schniz/fnm
If you know of any other popular ones, let me know. I'm keeping a list :)
