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.

Rust in Automotive
It’s definitely used for “nonsafety” stuff like infotainment. The ATSAMD HAL/PACs are probably the most complete embedded microcontroller family as far as Rust support goes, and that’s a part with heavy intent toward automotive use.

Looking for a highly resource constrained target to run Rust on. Any ideas?
The Rust ATSAMD community has been very helpful getting me going. I've really become fond of RTIC as a way to get a little structure in my programs.
- Code Rust in Aurdino??

Are there any ways to use rust for the Arduino MKR WiFi 1010?
The atsamd-rs rust folks (https://github.com/atsamd-rs/atsamd) have made this way easier! Check out my top level comment!

Hello, Microcontroller! Intro to video codecs and the "hello, world" of microcontrollers implemented in ~100 lines of dependency-free Rust
I'm obviously biased, but as a starting point I would recommend getting an Arduino and following the process in the article. Once you have a blinking LED, try it again using a HAL like atsamd-rs/atsamd. Then try making it more complex: configure the clock and replace the delay implementation with something that takes a proper duration argument, add serial IO via the USB port so you can communicate with your program as it runs, connect some more LEDs or buttons and interact with them, or make some network requests.

Writing embedded firmware using Rust
The embedded-hal project supplies these for a wide variety of controllers, for SAMD specifically, https://github.com/atsamd-rs/atsamd .

Want to Learn Programming and Microcontrollers?
Am admittedly too inexperienced to properly weigh the pros and cons of various platforms, but I find the Rust support for certain embedded platforms to be particularly compelling.
https://github.com/atsamd-rs/atsamd
I have at least managed to get some literal blinkenlights doing what I want on various Adafruit boards with very little effort.
- I’d like to learn rust to make a USB device that enumerates as a mouse to the OS and shakes the pointer every once in a while. I’m a web developer by trade. How realistic is this project?

Framework won't be just a laptop company anymore
> The CPUs in Oxide racks are AMD, so, presumably AMD-based compute rather than ARM.
These don’t run Hubris though; based on the chips directory in the repo [0], they’re targeting a mix of NXP and ST parts, which are Arm, and the user isn’t likely to see them or care what firmware they’re running: they’re really pretty “boring”.

Who killed the network switch? A Hubris Bug Story
I wouldn't put this comment here. It's not just some detail of this function; it's an invariant of the field that all writers have to respect (maybe this is the only one now but still) and all readers can take advantage of. So I'd add it to the `TaskDesc::regions` docstring. [1]

Oxide: The Cloud Computer
With respect to Hubris, the build badge was, in turns out, pointing to a stale workflow. (That is, the build was succeeding, but the build badge was busted.) This comment has been immortalized in the fix.[0]
With respect to Humility, I am going to resist the temptation of pointing out why one of those directories has a different nomenclature with respect to its delimiter -- and just leave it at this: if you really want to find some filthy code in Humility, you can do much, much better than that!

Barracuda Urges Replacing – Not Patching – Its Email Security Gateways
A lot of questions in there! Taking these in order:
1. We aren't making standalone servers: the Oxide compute sled comes in the Oxide rack. So are not (and do not intend to be) a drop in replacement for extant rack mounted servers.
2. We have taken a fundamentally different approach to firmware, with a true root of trust that can attest to the service processor -- which can turn attest to the system software. This prompts a lot of questions (e.g., who attests to the root of trust?), and there is a LOT to say about this; look for us to talk a lot more about this
3. In stark contrast (sadly) to nearly everyone else in the server space, the firmware we are developing is entirely open source. More details on that can be found in Cliff Biffle's 2021 OSFC talk and the Hubris and Humility repos.[0][1][2]
4. Definitely not vaporware! We are in the process of shipping to our first customers; you can follow our progress in our Oxide and Friends podcast.[3]

Spotting and Avoiding Heap Fragmentation in Rust Applications
everywhere, for example in https://github.com/oxidecomputer/hubris/search?q=dyn
Is Box really allocating here? Is the "Rust By Example" text incomplete?
Then I had to stop learning Rust for other reasons, but this doubt really hit me at the time.

What's the coolest thing you've done with Neovim?
I work on an embedded OS in Rust (Hubris) that has a very bespoke build system. As part of the build system, it has to set environmental variables based on (1) the target device and (2) the specific "task"; this is an OS with task-level isolation, so tasks are compiled as individual Rust crates.

TCG TPM2.0 implementations vulnerable to memory corruption
Oxide Computer told some storied about the difficulty of bring up of a new motherboard, and mentioned a lot of gotcha details and hack solutions for managing their AMD chip.
They talked about their bring up sequence, boot chain verification on their motherboard, and designing / creating / verifying their hardware root of trust.
I heard mention of this on a podcast recently, trying to find the reference.
I'm pretty sure it was [S3]

OpenAI Used Kenyan Workers on Less Than $2 per Hour to Make ChatGPT Less Toxic
When we started the company, we knew it would be a three year build -- and indeed, our first product is in the final stages of development (i.e. EMC/safety certification). We have been very transparent about our progress along the way[0][1][2][3][4][5][6][7] -- and our software is essentially all open source, so you can follow along there as well.[8][9][10]
If you are asking "does anyone want a rack-scale computer?" the (short) answer is: yes, they do. The on-prem market has been woefully underserved -- and there are plenty of folks who are sick of Dell/HPE/VMware/Cisco, to say nothing of those who are public cloud borne and wondering if they should perhaps own some of their own compute rather than rent it all.
