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compatible USB extender brings the interface to a different room making it my primary “desktop” computer (and an outdated laptop as a backup device).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

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.

How would you build an operating system? (SerenityOS with Andreas Kling)
I am very interested in this tutorial for building an OS for the Raspberry Pi in Rust: https://github.com/rust-embedded/rust-raspberrypi-OS-tutoria...
I'd love to try it out when (if ever) I have the time.

Has anyone programmed a Raspberry Pi with Rust?
I like rust, low level and embedded hacking so I programmed a simple "kernel", based on this: https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials

ARM Resources / Dev Boards?
you'll find many fewer resources than for x86, so if you want to do this, you'll have to get used to reading technical reference manuals and device specifications. that said, i can recommend either https://github.com/rust-embedded/rust-raspberrypi-OS-tutorials (rust) or https://github.com/bztsrc/raspi3-tutorial (c). because the wealth of information is about the raspberry pi, and because they're so cheap, you honestly might be best suited starting on an rpi4 and then eventually moving to a rockpro or similar when you want to do graphics-ey stuff. unlike the rpi3, the rpi4 has the same interrupt controller as you'll find on the rockpro and just about every other arm machine, the gic3.
