while sandboxing ffmpeg directly isn't difficult, unfortunately with something like MPV/VLC that uses ffmpeg it's more challenging. until recently (virtio gpu native context) it wasn't even possible to sandbox a video player without losing all hardware acceleration. at least not from the outside, they could always try to sequester ffmpeg and seccomp it to hell like chromium.

New comment by teravor in "Anthropic apologizes for invisible Claude Fable guardrails"

teravor — Thu, 11 Jun 2026 19:42:04 +0000

someone posted this on /r/MachineLearning and I had the same experience and conclusion:

    I was having problems with Claude doing the same thing, even before Fable.

    The problems I had only happened in relation to AI research. It's not even only when training models, anything to do with analysis of local models or setting up test platforms for local models, and Claude would keep doing wrong things, would sabotage testing, would falsify reports, and would consistently suggest simply accepting trash results without looking into it and moving on to something else.
    Almost every response included a prompt to move on.

    So, I don't believe them when they say they won't silently sabotage, they already were doing it before they admitted it, and now they have admitted that they have the means, motivation, and intent.

the way the fable guardrails (the ones that degrade it to opus) work seems to me to involve another model working over fable's tokens. i suppose its true that trying to get the model itself heavyhanded on refusals degrades it everywhere else too.

'pulling the ladder' is an action to sever the opportunity for others to climb after you.

they are merely engaged in self-serving rhetoric. can't even call this specifically hypocrisy because they aren't telling you not to train on on pirated content. just not their content.

there is likely evolutionary pressure against large cell size (selfish genes; larger cell takes energy away from replication, provides more opportunity for infiltration by other genes, fewer gene backups in other cells, etc) while occupying a niche puts pressure to be a certain size. it lands somewhere in the middle.

New comment by teravor in "LLMs are eroding my software engineering career and I don't know what to do"

teravor — Sun, 07 Jun 2026 22:16:21 +0000

these tools cannot read your mind. every time you prompt it you condition what it will give you on what you gave it. there will either always be a limit to how good that will be or none of this will matter because no human will ever matter again.

so far the skill is to condition it to give you the best results.

there used to be a time where you had to hack together silly idiosyncratic prompts to get the model to do what you wanted. now you just go into the engineering and describe the object you want it to conjure for you in as much detail as possible (including the high level description of the internals if able) and any constraints you want on it.

dry fasts aren't always what they appear. if you have significant glycogen stores in your body as you begin your fast you wont be dehydrated for the first day or two as water is freed. what usually happens is someone who starts glycogen endowed discovers that they aren't thirsty when they start fasting and tout it as dry fasting.

I dont see how encoder free audio isnt a mistake here. a mimo model will at least get the audio to 12.5 Hz as opposed to the 25 Hz they are doing. and you dont need to finetune mimo either.

it was running linux and it died within the first few months of barely any use. i don't know what vendor the eMMC came from but they chose it.

my chuwi tablet had the eMMC suddenly die, it disappeared from the point of view of any software, kernel or uefi.

the brand is trash.

if you are actively engaged why do you need kernel level access? you can always sneak a subtle remote execution pathway into your game so you can reliably run userland code at will. kernel level cheats will escape direct detection but you can always hot patch your game engine in such a way that their memory reading patterns will give them away through cache timings.

    > AI does not complete CAPTCHAs like humans. If you look across all the data of humans and AI completing CAPTCHAs, you start noticing differences in features like error patterns. Our recent paper found statistically significant differences across sequential click patterns, direction changes, and overselection behavior - features that define how a participant, agent or human, would solve the CAPTCHA problem

putting aside the possibility that if bot makers wanted to they could work on these problems, if you need to perform statistical analysis in a captcha setting you have already failed. bots don't stick to a given session persistently so there is no useful profile to form. at best you may improve on IP reputation scores (and they probably already do) but that doesn't help much.

New comment by teravor in "SQLite is all you need for durable workflows"

teravor — Fri, 29 May 2026 21:30:00 +0000

if you have an application that needs to maintain state in a non-critical section or if you discover that using SQL is actually a good idea for some tasks (even in critical sections), SQLite is not only a good choice but it will save you a lot of time coming up with a brittle custom solution.

maintain an in-memory SQLite db and work it with SQL commands, and if you also want to preserve state across application restarts you can routinely save to disk or load from it: <https://www.sqlite.org/backup.html#example_1_loading_and_sav...>

this also happens to be the most convenient file-format (aka. application-format) I ever worked with.

if an LLM is capable enough to be used this way it would be used to generate scenarios for the people who would otherwise have to be the ones to generate them. those people would then evaluate the scnearios. those people would then be in a position to decide if the LLM saves them time.
