Why does this spill over? Unlike CPU which is multiplexed by the kernel's scheduler (so infinite loops can't lock out other programs), is the GPU not multiplexed in the same fashion?

>For all trains to be self-driving

Given that we have self-driving cars, isn't this easier if someone really wanted? I guess compared to cars the marginal savings is not worth it though.

krackers··on Finder is so frustrating and has been since day one
I've never quite understood the hate either. But the way I see it is that it's not fundamentally inferior to explorer, but rather just has annoyances and warts that Apple has bizarrely not fixed for decades which makes tedious to use for anything other than casual browsing.

You can still navigate by path via cmd+shift+g (this works in the file picker too), but I feel like the popup animation used to be a lot quicker on older versions. You can customize views, but to get them to actually stick you have to use an arcane incantation (delete all existing ds_store, then go to view options menu and hit "make default").

You can cut-paste but you have to use cmd+c and cmd+option+v instead of cmd+x. There is an option to merge, it only appears under conditions: only when copy/pasting and only when "alt" is held in the dialog I think.

It also is really bad at browsing networked volumes, partly due to poor defaults as it tries to litter ds_store and generate thumbnails.

Opening a new tab always takes you back to the root directory instead of cloning your existing view. All of it is stuff that could be added in a simple point update rather than a ground-up rewrite.

krackers··on Actively exploited sandbox RCE in all Chromium versions
It mentions a type confusion in V8. Is it possible to trigger that without JS enabled?

The "all chromium versions" part of the title is also misleading, most browser CVEs do not distinguish between "untested lower bound" vs "affects all" (even though it seems like it'd be trivial to bisect).

Or equivalently could have gone down as a "deepseek" moment in TTS if the model was open-sourced (I don't think even a paper was published). It's a bit strange, he never made any profit but also never ended up publishing anything even after it was shut down.

Another benefit of open models is that you can mask out out words from logits directly when sampling. I wonder if anyone has put together a "desloppifier" for e.g. DeepSeek

krackers··on Anthropic's ‘watermark’ text adulteration in Claude is a perversion of writing
>fails to understand the gumbel softmax technique

I think in this case it doesn't help that there are multiple watermarking schemes, and the easiest for people to understand is the red/green scheme by Kirchenbauer et al. (https://arxiv.org/pdf/2301.10226), which does technically distort the logits (but I'd argue only in cases where you wouldn't notice it anyway).

I wasn't aware of this gumbel softmax scheme, it seems you're referring to https://simons.berkeley.edu/talks/scott-aaronson-ut-austin-o... ? That's really clever as it doesn't even distort the logits, basically cryptographically indistinguishable from a "real" random sample unless you have the key.

The actual scheme Claude uses seems to be neither of those two though, they say it is SynthId-text which seems to be tournament sampling based.

krackers··on Anthropic's ‘watermark’ text adulteration in Claude is a perversion of writing
I don't understand Gruber's points either, I wonder if there is some fundamental technical misunderstanding. Does he think that the logits should be sampled from in a "pure" manner without introducing any other bias? Does he know that there's already a sampling temperature, and that most providers have probably moved on to sampling strategies other than top-k? Does he know that the word choices have already been altered irreversibly during RLHF which is how you get the obvious Claudism like "load bearing" and "seams"?

Perhaps it would be useful to publish examples of samples with/without watermark. I'd suspect that the variability from simply sampling repeated times would dwarf any semantic differences you'd detect with the watermark.

krackers··on Claude Fable 5 Having Fun
>maybe some other biological organisms can experience

I don't think this even matters much in terms of moral patienthood. Many people might agree that cows can "feel pleasure" or "have fun", but yet they are slaughtered nonetheless. Dogs are only offered this not necessarily on account of their intelligence or the strength of their qualia but more because they're cute.

krackers··on Compression is prediction
I think it's limited to using base models (non post-trained), because the post-training would skew the logit distribution. There are ways to "coax" post-trained models back into behaving "like" a base model, I wonder if the benchmark could be unofficially updated with those somehow.
krackers··on What sort of maths are LLMs good at?
I think ARC-AGI-3 specifically forbids harnesses. This means that you're basically limited by the context window, so it's no wonder that LLMs can't do that well. Unofficial versions that use a harness seem to be doing fine on it.
