A Talk Near the Future of Python (a.k.a., Dave live-codes a WebAssembly Interpreter)

I agree with these, but David Beazley breaks most of them and his talks are way better than mine ;) e.g. ▶ this video

There was a youtube video a few years back that showed a guy livecoding...I think an ECMA interpreter, or maybe a WASM interpreter from scratch using some very easy to follow code. I can't remember what it was or the video, but it was gobsmacking. So instead here's another story. I once worked with an old Perl greybeard, he had written some kind of code that could parse an almost impossible large set of string formats that a large collection of automated systems produced except they all had some sort of non-standard/non-guaranteed formatting or semantics. Little bits and pieces (some semi-atomic bits) of them were semi-reliable, but the aggregate strings were just a huge mess, things came in all kinds of orders, had unreliable separators (if any) some things came in backwards, some forwards, and so on. You might imagine them to be things like IP addresses that sometimes had system names attached, sometimes locations, sometimes, no address, sometimes the address was separated by dots or commas, sometimes, pieces of equipment were listed. All legacy of decades of people slowly accruing bits and pieces of the larger system and naming things for local convenience rather for global understanding. As the systems rolled up these strings would sometimes get concatenated in different ways and in different orders. His code looked like total gibberish, a library of a bunch of code that sort of looked like Perl but also sort of looked like a custom rule language, it had something like 12

Any talk by Dylan Beattie[1,2] or David Beasley[3,4]. I think they are quite unique in their presentation, they tell a story. [1] link [2] link [3] link [4] ▶ this video

Sounds like this! Dave Beazley's A Talk Near the Future of Python (a.k.a., Dave live-codes a WebAssembly Interpreter) (2019) ▶ this video

I found this video ▶ this video "A Talk Near the Future of Python (a.k.a., Dave live-codes a WebAssembly Interpreter)" to be a brilliant introduction to WASM as well as writing interpreters in general. I'm a relative novice in the subject and it was pitched right at my level.

You're right about wasm not being too complicated, I've learned this when watching David Beazley coding a WebAssembly interpreter in under an hour. And it doesn't require any knowledge about it beforehand. ▶ this video

Ok, it wasnt technically this year but I have to share this one just incase anyone missed it, because it's quite possible the best conference talk I've ever seen. ▶ this video

I found this [1] quite interesting. It doesn't really answer any of the questions you asked, but I think it gives some interesting insights into WebAssembly, which might make it easier to put other things in context and also give a good low level understanding of it. It's the closing keynote talk at this year's PyCon India. From the description: > In this talk, I live-code a simple stack machine and turn it into an interpreter capable of running WebAssembly. I then use that to play a game written in Rust. ▶ this video

I recommand David Beazley's talk from a recent PyCon India on a similar subject : ▶ this video Mostly live coded, it really is pretty amazing but also quite insightful.
