A nano like text editor built with pure C
Most of that is probably attributable to being based on Kilo: https://github.com/antirez/kilo (kinda strange they didn't link directly in their readme) - a tiny text editor written by antirez who notably also created Redis. Antirez has a bunch of really interesting side projects if you dig into their github repo.

Micro – A Modern Alternative to Nano
Yeah, "micro" for an editor would be 11 kilo bytes. I bet it's possible to do a half-decent editor in C in 11KB. Antirez's "kilo" (~1000 lines of C) is 36KB when compiled with standard gcc (https://github.com/antirez/kilo).
That said, for many server-type use cases these days, 11MB isn't a huge deal. Still, I wonder if micro could be compiled on / ported to TinyGo and end up a few hundred KB? It looks like TinyGo can produce some pretty small binaries: https://tinygo.org/docs/guides/optimizing-binaries/

What happens when you press a key in your terminal?
Anyone interested in the machinations of all of this terminal stuff should look at antirez’ kilo, a terminal text editor in under 1000 lines of code: https://github.com/antirez/kilo
There is a nice tutorial that walks through how one might write it from scratch: https://viewsourcecode.org/snaptoken/kilo/

A simple terminal game
I always wondered how people get stuff animated on the terminal but I never had the time to look into it up until a few years ago when someone on the internet released an awesome guide on how to create a text editor in less than 1000 lines of C. What caught my attention about this was that it was based on Antirez' kilo - which is a terminal based editor.

Ask HN: How to learn about text editor architectures and implementations?
You could start by looking at something super simple like Kilo:
https://github.com/antirez/kilo
Even I could understand this one pretty well and that's no small matter.

Ginkgo: A WIP small text editor built entirely in Rust with cursor control and select Vim features
I just started learning Rust 2 weeks ago, and I wanted to apply my learning towards a project.Ginkgo is a small text editor built entirely in Rust. It takes inspiration from the famous tiny C-based text editor, Kilo. It also includes many Vim inspired keybindings and features such as normal/insert modes. For convenience, it also has added mouse cursor support!
- What would one need to know in order to develop an in-shell VIM like code editor?

Any interesting project ideas in c language
Write your own editor. As an example: kilo

Wasm3 entering a minimal maintenance phase
This means that newly created wasm blobs will stop being able to run in wasm3.
On a side note, I can't help feeling sorry for the people that advocate for C over C++ when I see commits like https://github.com/wasm3/wasm3/commit/121575febe8aa1b544fbcb...

Towards a modern Web stack (by Ian Hickson, author of the HTML5 spec and current Flutter tech lead)
On other benchmarks I'm seeing numbers closer to 20% slower, e.g. https://github.com/wasm3/wasm3/blob/main/docs/Performance.md and https://github.com/second-state/wasm32-wasi-benchmark. It's numerical code, which is the best case scenario for a native binary. It's much closer on an average web app or server workload, e.g. https://krausest.github.io/js-framework-benchmark/current.html - you can find WASM frameworks that beat most JS frameworks on there, but that is not as impressive considering the state of the JS ecosystem. Overall, it's already under 50%, and there is still plenty of room for improvement.

Show HN: I wrote a WebAssembly Interpreter and Toolkit in C
Can miniwasm share memory with the host? wasm3 doesn't allow this[1] and requires you to allocate VM memory and pass it to the host, but that has several downsides (some buffers come from external sources so this requires a memcpy; the VM memory location isn't stable so you can't store a pointer to it on the host; etc.).
I'm really interested in a fast interpreter-only Wasm VM that can allow the host to share some of its memory with the VM.

The Pine Formula
> This product family will never run Linux, as developers will need to develop a new firmware from scratch. This is obviously not a problem for the earbuds, but a big limitation for the player
Perhaps not Linux, but I suspect there would be a place here for a Unix-like platform that feels familiar. If for example we could get wide-adoption of something like the JVM or wasm3 [0] on these platforms, code could become quite portable, despite wildly different architectures.
For example, Apache's NuttX [1] (that I first learned from Lupyuen, a guy making great progress working with Pine64 products).
> Processing wise, this chip is well sufficient for TWS headphones, but very inadequate for an audio player. It will not drive a good screen, it nor run high-resolution flacs or (probably?) support a high-quality, high-bandwidth codec. In fact, a first generation iPod Nano (retailing for $149 in 2006) had 16MB RAM, so over 16 times what the PinePod would offer. In fact, even the features of any custom firmware are limited from so little memory
I wouldn't call it time just yet. Displays can be interacted with intelligently (to reduce pixel bandwidth) and ultra high quality audio codecs offer diminishing returns, especially when you don't have a DAC or headphones to make the most of them.
My advice to Pine64 would be this:
1. Consolidate your product lines. The Pinebook is just a slower Pinebook Pro, just go with the Pinebook Pro. The PineTab is just a Pinebook without the keyboard, again I would consolidate this with the Pinebook Pro and just make the keyboard detachable.
2. The SBCs should just go straight into the device, thus creating a clear upgrade path for future products. If you want a PineBook Pro running Quartz, just swap the boards (of course with daughter boards for USB expansion, display driver, power, etc).
3. Don't be afraid to kill off products. The Pinebook and PineTab have never seen a new release. The PinePhone appears to be taking a back seat to the PinePhone Pro. The PineCube is basically DoA due to the processing power struggling to process the camera image.
More generally, try to do fewer things, but do them well.

Take More Screenshots
I think SIMD was a distraction to our conversation, most code doesn't use it and in the future the length agnostic, flexible vectors; https://github.com/WebAssembly/flexible-vectors/blob/master/... are a better solution. They are a lot like RVV; https://github.com/riscv/riscv-v-spec, research around vector processing is why RISC-V exists in the first place!
I was trying to find the smallest Rust Wasm interpreters I could find, I should have read the source first, I only really use wasmtime, but this one looks very interesting, zero deps, zero unsafe.

I get what you are saying as to be so small that there isn't a place of bugs to hide.
> “There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult.” CAR Hoare
Even a 100 line program can't be guaranteed to be free of bugs. These programs need embedded tests to ensure that the layer below them is functioning as intended. They cannot and should not run open loop. Speaking of 300+ reimplementations, I am sure that RISC-V has already exceeded that. The smallest readable implementation is like 200 lines of code; https://github.com/BrunoLevy/learn-fpga/blob/master/FemtoRV/...
I don't think Wasm suffers from the base extension issue you bring up. It will get larger, but 1.0 has the right algebraic properties to be useful forever. Wasm does require an environment, for archival purposes that environment should be written in Wasm, with api for instantiating more envs passed into the first env. There are two solutions to the Wasm generating and calling Wasm problem. First would be a trampoline, where one returns Wasm from the first Wasm program which is then re-instantiated by the outer env. The other would be to pass in the api to create new Wasm envs over existing memory buffers.
See, https://copy.sh/v86/
MS-DOS, NES or C64 are useful for archival purposes because they are dead, frozen in time along with a large corpus of software. But there is a ton of complexity in implementing those systems with enough fidelity to run software.
Lua, Typed Assembly; https://en.wikipedia.org/wiki/Typed_assembly_language and Sector Lisp; https://github.com/jart/sectorlisp seem to have the right minimalism and compactness for archival purposes. Maybe it is sectorlisp+rv32+wasm.
If there are directions you would like Wasm to go, I really recommend attending the Wasm CG meetings.
https://github.com/WebAssembly/meetings
When it comes to an archival system, I'd like it to be able to run anything from an era, not just specially crafted binaries. I think Wasm meets that goal.
