• WASI 0.2.0 and Why It Matters
  8 projects | news.ycombinator.com | 26 Jan 2024

  WASI Co-chair here. Nothing in WASI is "somehow blocked by Google", or indeed blocked by anyone at all. Graphics support in WASI hasn't been developed simply because nobody has put energy into developing graphics support in WASI.

  At the end of 2023 we counted around 40 contributors who have been working on WASI specifications and implementations: https://github.com/WebAssembly/meetings/blob/main/wasi/2023/... . That is a great growth for our project from a few years ago when that issue was filed, but as you can see from what people are working on, its all much more foundational pieces than a graphics interface. Also, if you look at who is employing those contributors, its largely vendors who are interested in WASI in the context of serverless. That doesn't mean WASI is limited to only serverless, but that has been the focus from contributors so far.

  By rolling out WASI on top of the WASM Component Model we have built a sound foundation for creating WASI proposals that support more problem domains, such as embedded systems (@mc_woods and his colleagues are helping with this), or graphics if someone is interested in putting in the work. Our guide to how to create proposals is found here: https://github.com/WebAssembly/WASI/blob/main/Contributing.m... .

• WASM: Big Deal or Little Deal?
  5 projects | news.ycombinator.com | 5 Sep 2023

  For me, the huge missing link (that is fortunately being worked on!) is being able to (in a performant way) have a good answer for "host code wants to do some blocking operation, WASM should suspend during the operation".

  This _should_ be gotten thanks to work on stack switching in WASM. As of the most recent working group meeting on this [0], it seems like V8 has made a good amount of progress on this. They published a thing back in January[1] on this, and hopefully if things go well and this is available across WASM engines then there will be one less "JS-ism" (everything async) that causes issues for transpilation.

• Goodbye to the C++ Implementation of Zig

  Mozilla created a precursor technology, but I thought Wasm was developed via the W3C standards process from the start. From the notes of the first meeting, you can see attendees from Adobe, Apple, ARM, Autodesk, Google, Intel, Mozilla, Stanford, and more.

  Additionally, Wasm has been a W3C standard since 2019.

• Wasm difficulties in Rust, Haskell, and Go
  9 projects | dev.to | 30 Nov 2022

  A bunch of packages like tokio don't work because they transitively depend on net, and WASI doesn't have networking yet (networking is in phase 1 of 5), and it doesn't seem possible to turn off the net feature of transitive dependencies

  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.

  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.

• WebAssembly 2.0 Working Draft
  21 projects | news.ycombinator.com | 19 Apr 2022

  The simplest way to get involved is to start attending the biweekly standardization meetings. The agendas are organized here: https://github.com/WebAssembly/meetings

  To attend the meetings, first join the W3C WebAssembly Community Group here: https://www.w3.org/groups/cg/webassembly, then email the CG chairs at [email protected] to ask for an invite.

  From there you'll get a sense of who folks are so you can pair names with faces when contributing to the various proposal discussions on the many proposal repos listed here: https://github.com/webassembly/proposals.

  To get a sense of how things are run and decided, read the process documents here: https://github.com/WebAssembly/meetings/tree/main/process. The TL;DR is that the community group and its subgroups decide everything by consensus via votes during the meetings.
