there are more demos which are an even larger deal btw #vagueposting

testing http stuff after fixing closure bugs, it crashed so I thought I had a regression but just forgot I changed my hello world to this yesterday

half my remaining regressions are actually tests which were false positive due to now fixed bugs 😳

fixing regression hell from a ~5k diff 🥴

real world load testing! with 3K req/s (2.5M requests total), I peaked at: ~22% usage of 1 core, ~2.6MB memory usage, 9ms p99 response time. went better than expected 🥳

today in unnecessary infrastructure: made my own status page from scratch with automated incidents, paging. it's also hosted independently so in critical incidents it would remain up status.porch.porffor.dev

grafana posting will continue until morale improves

I got hooked on self-hosting so I made my own entire framework and deployment stack running on my own hardware. porffor.dev and goose.icu have been running on it for a few days. no I wouldn't recommend doing this sort of thing for serious use (and no I won't release it) but it is very fun!

porffor.dev is now served by a Porffor-compiled TS native binary!

I will (suddenly) be at fosdem if you want to meet up!

My ahead-of-time JS engine Porffor eliminates JS cold starts on AWS Lambda. 12x faster and 2x cheaper than managed Node. Still very early but these results should speak for themselves :) goose.icu/lambda/

If you have AWS Lambdas with a small amount of (Node)JS please DM me :)

Porffor now passes over 60% of Test262, thanks to a new custom regex engine!

Porffor now has its own fuzzer which abuses the compiler with randomly generated JS code in an attempt to find bugs which would otherwise not be found to help stability!

ECMAScript excitement 😉 Congrats to @goose.icu on advancing the Math.clamp proposal to Stage 2 at TC39 today 🎉 Math.clamp(number, min, max) constrains the number to be between the stated range 👍 github.com/tc39/proposa...

Porffor now passes over 59% of Test262!

Porffor's Wasm is now faster than *native* Node JITless at richards.js, an old V8 benchmark! new improvement is thanks to a new compiler feature and a minor object rewrite I'll post about this weekend. I still have ideas which can make this hopefully almost 2x faster this month!

introducing porffor profile, an easy to use but detailed profiler, with shareable links!

just had a great catch up with @goose.icu on porffor progress. keep an eye on this project 👀 there's so many perf gains to be had from it once it is stable

Porffor now supports BigInt typed arrays: just this (plus some related changes) boosts Test262 passing by over 0.7%!

Porffor now passes over 57% of Test262! This latest bump was thanks to a refactor makes functions and methods distinct to be more conformant for this, construction, etc

new js engine (quickjs fork) just dropped: github.com/lynx-family/...

american tv makes me laugh every time

I love @goose.icu's Porffor Test262 compatibility plot, I'd love to make one for @convex.dev's JS Runtime (so for runtime features, not languages features)

travel friends I got SSSSd for the first time (hello Seattle)

Porffor US tour 🌎 - Seattle Feb 17-23 (TC39 plenary) - SF Feb 24-Mar 12 - Richmond (VA) Mar 13-16 (@rvajavascript.bsky.social)

this gave me an idea... decorating typescript functions to just in time compile and execute them in web assembly with Porffor. it works!!

any recommendations for places to long-stay (~2 weeks) in SF?

I'll be here and in Seattle that week for TC39! :)

Porffor compiling to Wasm is now faster than QuickJS interpreting natively for an older V8 benchmark!

RVA JS Conf confirmed speakers & presentations. Super excited to announce that Oliver Medhurst is coming across the pond from the UK for this talk - Compiling JavaScript ahead-of-time with Porffor from @goose.icu , Founder at Porffor.

I rewrote Porffor's object implementation completely; it is now much faster and makes Wasm binaries 2-5x smaller than before when using objects! Porffor's current worst benchmark gets 30% faster with >4x smaller Wasm; almost on par with QuickJS with only ~1 month of work! goose.icu/porffor-obje...

I’ve been helping (alongside others) to Champion Temporal for around 6 years now, it’s great to see it approaching the finish line. The responses have been positive. Great work @joshcena.com and @meyerweb.com on the MDN documentation, momentous effort. Also props to the main man @ptomato.name

optimization made conformance go up a bunch while making slightly smaller+faster Wasm 🚀📈

📅 Save the dates! The Web Engines Hackfest 2025 will take place June 2-4 in A Coruña, Galicia (Spain). Check more details at: webengineshackfest.org

Porffor's goals for January: A more compliant and stable compiler, while starting foundations for large long-term optimizations. goose.icu/porffor-goal...

Playing with an Arduino with my kiddo, and I'm having to brush off my limited decades-old C knowledge 😬 I wish @goose.icu 's Porffor was ready and somehow usable for it!

is saying "semver is not good for everything" a hot take?

Ecma just approved the 1st edition of the new "Source map format" standard, ECMA-426! 🎉 tc39.es/ecma426/2024/

Now 56%!

Porffor now passes over 55% of Test262, jumping by over 4% thanks to fixing a bug which broke class expressions 😅

if someone does `runtime example.com/foo.js%60 should it ask the user before downloading/running/using it (via stdin)?

down to 25 malformed Wasm Test262 errors from 146 a week ago, stability++ 🤠

spent all day doing an internal rewrite mostly for maintability/DX and compile time, but this also halved malformed Wasm output errors for Test262 (145 -> 67) gaining a free almost 0.1%! github.com/CanadaHonk/p...

Porffor compiler line count over time; the distinction between languages is very useful as JS = compiler, TS = built-ins

Informally beginning a bug bounty program for Porffor: offering $100 to anyone who can *run arbitrary code/commands via Porffor only compiling* (`porf wasm foo.js foo.wasm`). 90% sure this is impossible so putting own money on the line ;) (if people are interested in why I think so I can say more)

Checking if a value is "fully" truthy (like !!foo) is now ~2x as fast as before in Porffor

close to making my own Wasm REPL/playground I can just give instructions to and get an output, because this doesn't exist yet? (or at least a fully supported/compliant version)

what is the most awkward/hard to answer tech-field question people ask you?

wanting to do an office hours type of livestream but ideally it would be me and someone else yapping not just me lol
