Happening already. My new claude max account got instabanned after just a few messages asking it to debug some stuff for me, that they felt like a TOS violation. Nothing remotely controversial. The main model didn't even complain, some dumber background censorship model flagged it.

Lucky you. My new claude max account simply got instabanned. All I asked it was to build node and V8 "to investigate some node crashes" (the part I think it overindexed on) and look into a few diffs. And bam, "An internal investigation of suspicious signals associated with your account indicates a violation of our Usage Policy. As a result, we have revoked your access to Claude"

They are even worse than Google, which at least doesn't ban your whole account if you search the wrong thing.

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.

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.

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.

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.

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!

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.

VPNs are widespread in Russia, so they probably misattribute a good chunk of the traffic.

"By 2025, about 41% of Russian internet users were relying on VPNs — one of the highest adoption rates in the world." [1]

But memory bandwidth (bottleneck for LLM inference) is only marginally improved, 614 GB/s vs 546 GB/s for M4/M5 Max - where is this 4x improvement coming from?

I think I'll pass on upgrading.
