TinyGo VS biscuit

Reading through the documentation, you will understand why this plugin is called "tiny," i.e., the SDK uses the TinyGo compiler instead of the official Go compiler. You can read more about why this is the case on the SDK\'s overview page, but the TLDR version is that the Go compiler can only produce Wasm binaries that run in the browser.

Not only you can fit Go into a kernel, there is at least two products that do so.

TamaGo, used to write the firmware used in USB armory.

TinyGo, which even has official Arduino and ARM support, and is sponsored by Google

Ah but that isn't proper Go! Well neither is the C code that is allowed to be used in typical kernel code, almost nothing from ISO C standard library is available, and usually plenty of compiler specific language extensions are used instead.

Reminds me of https://tinygo.org/ - a project that brings Golang to embedded devices, browser (wasm) contexts. Do you converge or diverge from that project?

You should also consider TinyGo. It can compile Go for the Pico, and is starting to get good device support.

Thankfully some folks completly ignored whatever the rest of the world thinks system programming is all about and created:

- TinyGo (https://tinygo.org/), which is acknowledged by people in the industry[0][1]

- TamaGo unikernel on USB Armory secure key (https://www.withsecure.com/de/solutions/innovative-security-...)

And then there is the question if writing compilers, assemblers, linkers is systems programming or not.

Have you seen TinyGo? In the case of embedded system I would probably still chose C over Rust if the system didn't support dynamic memory allocation, and most embedded systems do not.

>I really hate how for microcontrollers the only two choices are either C++ or Micropython

There's TinyGo as well. https://tinygo.org/

Gist link fixed, thanks. Compared to TinyGo, Go with GOOS=wasip1 will probably generate larger artifacts (at least, for now). This is because it bundles the entire Go runtime. The benefit is that it fully supports goroutine scheduling and non-blocking I/O. TinyGo (I believe) still uses a custom asyncify pass and does not support non-blocking I/O nor basic WASI networking (e.g. https://github.com/tinygo-org/tinygo/pull/2748 never landed, but GOOS=wasip1 supports it).

No, it isn't the third release of a POSIX like OS research written in Go,

But there are other brave people exists like biscuit or gopher-os who can do it :)))

That's something I found in doing a bit of a dive on why ripgrep is so fast at doing a very specific kind of string search workload (Gallant / burntsushi / author of ripgrep is an actual wizard and contributes to Rust's regex engines, for reference). I wrote tiny proof of concepts in a variety of languages, all in my same style -- and sometimes my Go variants were as fast as the equivalent Rust/C (even in release / -O3/2 (every once in a blue moon, O3 makes no diff or is a slight regression in some exec paths)). I eventually found something about benchmarks in a related area, leading to this: https://benhoyt.com/writings/count-words/#performance-results-and-learnings. Somebody on the Go sub even linked me to the Biscuit OS: https://pdos.csail.mit.edu/papers/biscuit.pdf, which, tidbit, has Jon Gjengset (Crust of Rust legend) in the contribs list (https://github.com/mit-pdos/biscuit).

https://github.com/mit-pdos/biscuit maybe this

Go has been used to implement OS kernel code, e.g. in the Biscuit OS from MIT: https://github.com/mit-pdos/biscuit

Of course, the garbage collector did not exactly make it easier - but it's an interesting piece of software.

https://github.com/mit-pdos/biscuit says 5% slowdown over C. Garbage collection is going to require some more RAM, generally <=2x though.
