Assuming CRIU can checkpoint and restore Chrome, and especially recent versions of Chrome, just fine, is a little bit of stretch.

z.ai posted an announcement earlier that day (in GMT+8) saying that they will make GLM-5.2 available later today at 5:21pm so it can't be a coincidence.

Good troll.

At this scale thinking tokens don't matter anymore.

In Feb Anthropic called out three Chinese labs for "distillation attacks", but a lab missing in their post actually had most Claude generated tokens among all Chinese labs in their midtrain data :p

Glad to hear that as I have some fun challenge ideas that would be otherwise too tedious to solve.

> work stealing executors have long been known to offer significantly lower latency with more consistent P99 than traditional threads. This has been known since forever - in the early 00s

Well, we know how to make "traditional threads" fast, with lower latency and more consistent P99 since forever^2, in the early 90s. [1]

Sure, we can't convince that Finnish guy this is worthwhile to include in THE kernel, despite similar ideas had been running in Google datacenters for idk how many years, 15 years+? But nothing stops us from doing it in the userspace, just as you said, a work stealing executor. And no, no coloring.

Stack is all you need. Just make your "coroutines" stackful. Done. All those attempts trying to be "zero-cost" and change programming model dramatically to avoid a stack, introduced much more overhead than a stack and a piece of decent context switch code.

> You can tell async is directionally kind of correct in that io_uring is the kernel’s approach

lol, it is very hard to model anything proactor like io_uring with async Rust due to its defects.

Another case: People who want to run workloads that are inherently incompatible with Kubernetes networking model.

For example:

* For some cursed reasons you want to make sure every single one instance of a large batch job see just one NIC in its container and they are all the same IP and you NAT to the outside world. Ingress? What ingress? This is a batch job!

* Like the previous point, except that your "batch job" somehow has multiple containers in one instance now, and they should be able to reach each other by domain.

The problem here is both aimed for Day 0 support, both got embargoed preliminary model weights and arch, and I don't think they have access to the other sides embargoed code.

> I read about 30% and got bored.

I was lucky then :) Somehow I saw this first. And then the "somewhat reliably writing exploits for SpiderMonkey" part, and then the crypto libraries part. Finally I wonder why is there a Linux LPE mini writeup and realized it's the "automatically turn a syzkaller report to a working exploit" part.

Now that I read the first few things (meh bugs in OpenBSD, FFmpeg, FreeBSD etc) they are indeed all pretty boring!

> Mythos Preview identified a memory-corruption vulnerability in a production memory-safe VMM. This vulnerability has not been patched, so we neither name the project nor discuss details of the exploit.

Good morning Sir.

> Has anything changed here? I don't pay much attention but KASLR was considered basically useless for preventing LPE a few years ago.

No. It's still like this. Bonus point that there are always free KASLR leaks (prefetch side-channels).

But then, this thing is just.. I don't have a word for this. Just randomly read paragraphs from the post and it's like, what?

> However, if it can't figure out to render the json to a visual on its own does it really qualify as AGI? I'd still say the benchmark is doing its job here.

Can you render serialized JSON text blob to a visual with your brain only? The model can't do anything better than this - no harness means no tool at all, no way to e.g. implement a visualizer in whatever programming language and run it.

Why don't human testers receive the same JSON text blob and no visualizers? It's like giving human testers a harness (a playable visualizer), but deliberately cripples it for the model.

Mostly high end lithography.

They can copy it. And no, the software moat is not there if someone choose the blatant copy route. They just can't build it in the scale they want yet.

> what if they just use 12nm and create GPUs with much bigger size but comparable performance

Physics do not work this way :/

TBH they really shouldn't have posted such a tweet in the first place, just sit back and watch their license enforced by the Internet.

I had the question "how do you even enforce this weird license term" back then, I guess I know the answer now.

For another example, Singapore, one of the "many Asian countries" you mentioned, list "Chinese New Year" as the official name on government websites. [0] Also note that both California and New York is not located in Asia.

And don't get me started with "Lunar New Year? What Lunar New Year? Islamic Lunar New Year? Jewish Lunar New Year? CHINESE Lunar New Year?".

Sometimes people are too lazy to write their own agent loop and decided to run off-the-shelf coding agent (e.g. Claude Code, or Pi in case of clawdbot) in environment.

looks like AI slop ware :( I hope they didn't actually run it.

This is the only factor. People sometimes perceive Apple's NPU as "fast" and "amazing" which is simply false.

It's just that NVIDIA GPU sucks (relatively) at *single-user* LLM inference and it makes people feel like Apple not so bad.
