Nothing new. Classic joke goes like

$100/hr standard rate

$150/hr if you watch

$175/hr if you help

$250/hr if you tell me how to do my job

You can prompt an LLM to generate tests from the spec and I'd bet it would easily get most of the way there, especially if you give it a reference implementation to test against. I did just that, though on a small scale - just for feature tests. The last few percent would be the real challenge, you probably don't want it to just imitate another implementation's bugs.

Reference implementation that someone else — a human, wrote? Hm… so one way or another, some humans’ labour is laundered…

Don't we all stand on the shoulders of giants?

I have never attempted to take credit for someone's work, nor ever put serious effort into hiding someone's contribution. LLMs are purpose-designed for that.

More like 8th. These pass nearly all Temporal tests as well: v8, spidermonkey, libjs, boa, escargot, kiesel, jint. Almost there: graaljs, yavashark.

They really did manage to benchmaxx test262 and beat everyone at it. In my testing (all engines with experimental flags in same conditions on full test262):

  99.5 jsse
  99.1 v8
  99.0 spidermonkey
  98.1 libjs
  97.4 escargot
  97.3 jint
  96.4 boa
  95.0 graaljs
  93.2 kiesel
  92.1 jsc
  82.8 quickjs
  82.5 quickjs-ng
  82.1 xs
  80.1 brimstone
  77.7 nova
  74.6 jerryscript
  66.5 sobek
  65.5 goja

It ain't fast (~10x slower than boa), but very compliant.

You can run just run whole Windows with IE6 in the browser these days thanks to WebAssembly: https://oldweb.today/?browser=ie6. It even works on my phone.

That’s actually pretty interesting

I’m not very optimistic given how tightly this thing is coupled to Windows and ActiveX, but I might still give it a try just out of curiosity.

If you can make it run in a standard qemu/libvirt VM, you likely should be able to ship that VM in the browser as the site I linked demonstrates.

Only problem I see is, does it need custom hardware/drivers? If yes and you can make hardware passthrough work with qemu, perhaps you could host a VM instance on a server and ship some web UI or RDP client for users to connect to it.

Eh, marketing fluff. This is more like it: https://oldweb.today/ - browse old web (from archive.org) with old browsers (in Wasm)

A better way to celebrate 30 years of their browser would be to just open source it. Code's been leaked and irrelevant today anyway but still.

Eh, it's been cheaper and better for a long time to just demolish and rebuild rather than deal with neverending issues at major fixer uppers. Robots probably would be able to do uncomplicated cookie-cutter builds in a decade or two, there's just too much money in the construction sector that AI companies looking for the next big thing to disrupt can't ignore.

Found this gem today: https://github.com/pmatos/jsse/ - "An agent-coded JS engine in Rust. I didn't touch a single line of code here... didn't even create this repo by hand -- my agent did that."

Passes 99.96% of test262 - that's more than V8 & co!

nice one lol

Security / Finance. People aren't going to trust slop to make critical decisions for a long time.

Any niche areas - once you venture outside of topics/tasks well represented on the Internet and GitHub, even frontier LLMs still quickly take a nosedive.
