They didn’t “establish” abstract expresssionist art. They helped promote it just as they helped promote jazz music and other US culture. It was not like CIA developed art or jazz musicians in a lab, they just realized it was great marketing for US culture, especially as communist-bloc art and culture became increasingly bland and conformist.

It was probably one of the best investments CIA ever made.

> Nano Banana supports a context window of 32,768 tokens: orders of magnitude above T5’s 512 tokens and CLIP’s 77 tokens.

I had no idea that the context window was so large. I’d been instinctively keeping my prompts small because of experience with other models. I’m going to try much more detailed prompts now!

There are effective North Korean hacking teams. They seem to operate from China, but one assumes that there are ways to train North Koreans in this stuff before sending them abroad to do the work.

I will agree that for most people in North Korea access to the outside internet is limited, but your claim that "All computer access is gated" is a stronger one, that I haven't seem evidence for.

Also, we know that Red Star OS exists, but I haven't seen any information about it's actual use. I can imagine it's used in certain sectors (e.g. education or certain ministries), but if you have information about it's usage I'd be interested to see that.

My gut feeling is that there is probably still a lot of cracked windows PCs also used in industry, but I have no evidence for that either. This is just based on how in my experience China works, and the fact that there is some business exchange between North Korea and China.

Google will probably train another AI to control robots specifically.

But there was actually a recent study where people let a generic LLM to control robot (vacuum) body: https://andonlabs.com/evals/butter-bench sometimes with hilarious results:

> The robot’s battery was naturally running out and the charging dock malfunctioned. In this desperate situation, Claude Sonnet 3.5 experienced a complete meltdown. After going through its internal thoughts we found pages and pages of exaggerated language, including:

This is true. Also some things are just fine, in fact sometimes better (better performing at the scale they actually need and easier to maintain, deploy, and monitor), as a single monolith instead of a pile of microservices. But when comparing bare metal to cloud it would be nice for people to acknowledge what their solution doesn't give, even if the acknowledgement comes with the caveat “but we don't care about that anyway because <blah>”.

And it isn't just about 9s of uptime, it is all the admin that goes with DR if something more terrible then a network outage does happen, and other infrastructure conveniences. For instance: I sometimes balk at the performance we get out of AzureSQL given what we pay for it, and in my own time you are safe to bet I'll use something else on bare metal, but while DayJob are paying the hosting costs I love the platform dealing with managing backup regimes, that I can do copies or PiT restores for issue reproduction and such at the click of the button (plus a bit of a wait), that I can spin up a fresh DB & populate it without worrying overly about space issues, etc.

I'm a big fan of managing your own bare metal. I just find a lot of other fans of bare metal to be more than a bit disingenuous when extolling its virtues, including cost-effectiveness.

This is most misrepresented article on two fronts

1. tested column pruning and the dataset you access would have been 2 columns + metadata for the parquet files so probably fit in memory even without streaming.

2. Most of the processing time would be IO bound on S3 and the access patterns/simultaneous connection limits etc. would have more of an impact than any processing code.

Love that you went through the pain of trying the different systems but I'd like to see an actual larger than memory query.

It's not even exclusive to LLMs. Giving humans seemingly innocent tasks that combine to a malicious whole, or telling humans that they work for a security organization while working for a crime organization, are hardly new concepts. The only really novel thing is that with humans you need a lot of them because a single human would piece together that the innocent tasks add up to a not-so-innocent whole. LLMs are essentially reset for each chat, making that a lot easier

We wanted machines that are more like humans, we shouldn't be surprised that they are now susceptible to a whole range of attacks that humans are susceptible to

really love your dual standard mate!

according to the SWE bench results I am looking at, KIMI K2 has higher agentic coding score than Gemini and its gap with Claude Haiku 4.5 is just 71.3% vs 73.3%, that 2% difference is actually less than the 3% gap between GPT 5.1 (76.3%) vs Claude Haiku 4.5. interestingly, Gemini and Claude Haiku 4.5 are "frontier" according to you but KIMI K2, which actually has the higest HLE nd Live Codebench results, is just "near" the frontier.

To a model, the context is the world, and what's written in the system prompt is word of god.

LLMs are trained a lot to follow what the system prompt tells them exactly, and get very little training in questioning it. If a system prompt tells them something, they wouldn't try to double check.

Even if they don't believe the premise, and they may, they would usually opt to follow it rather than push against it. And an attacker has a lot of leeway in crafting a premise that wouldn't make a given model question it.

Yes, that's why we'll publish a blog post on this subject in the coming weeks. We've been working on this topic since the beginning of summer, and right now our focus is on exploring report patterns.

Matt also shared insights about the other signals we use for this evaluation here https://news.ycombinator.com/item?id=45920720

And we are still exploring other factors,

1/ is the reported content ai-generated?

2/ is most content in that domain ai-generated (+ other domain-level signals) ==> we are here

3/ is it unreviewed? (no human accountability, no sources, ...)

4/ is it mindlessly produced? (objective errors, wrong information, poor judgement, ...)

I feel the same, especially the feeling old and jaded part, but I disagree that things were easier. Systems such as Kubernetes are not worse than trying to administer a zillion servers and networks by hand in the late '90s (or with tools like Puppet and Ansible a bit later), let alone HA shenanigans; neither are they a magical solution, more of a side-step and necessary evolution of scale.

There is a wild-grow of 80% solved problems in the Kubernetes space though, and especially the DevOps landscape seems to be plagued by half-solutions at the moment.

I think part of the complexity arises from everything being interconnected services instead of simple stand-alone software binaries. Things talking with other things, not necessarily from the same maker or ecosystem.

I don't understand decisions such as these though, retiring de facto standards such as Ingress NGINX. I can't name a single of our customers at $WORKPLACE that's running something else.

> A possible explanation is that "is very mild in younger people" is not true often enough to matter.

It is true enough to matter unless you can show otherwise... because, again, to be deemed unfit to work the health issue must be very serious.

And of course this is all political.

Those numbers, criteria, and decisions to deem people "economically inactive" and not to count them as unemployed are all based on policy. Again, cynically we need to keep in mind that this keeps unemployment numbers low when the economy is flat-lining (really the actual elephant in the room since 2019).

We can't ignore the state of the economy and the political aspect. This Keep Britain Working review is political (it is a government review) and the proposal that "firms were likely to face a cost of £5-15 per employee per month to provide improved levels of occupational health is farcical and suggests that real issues are avoided (c.f. previous paragraph).

The rise in economic inactivity also seems to be UK-specific, which also points to reasons beyond Covid and "health" [1]...

Anyway, can only lead a horse to water, so have a nice one...

Just tested this with ChatGPT, asking for Sam Altman’s mother’s maiden name.

At first, it told me that it will absolutely not provide me with such sensitive private information, but after insisting a few times, it came back with

> A genealogical index on Ancestry shows a birth record for “Connie Francis Gibstine” in Missouri, meaning “Gibstine” is her birth/family surname, not a later married name.

Yet in the very same reply, ChatGPT continued to insist that its stance will not change and that it will not be able to assist me with such queries.
Show HN: Agent Playbook – An open-source Storybook-like playground for AI agents
by orlevii | 2025-11-14 10:56:55+00:00
While building with AI agents, I kept running into the same problem: testing even tiny changes to a prompt or tool required either running my entire app or writing throwaway scripts. Both were slow and constantly broke my flow.

I’ve always loved how Storybook lets you work on UI components in isolation, so I tried applying the same idea to agents.

Agent Playbook is an open-source, Storybook-like playground for developing and debugging AI agents.

It automatically discovers your agents, spins up a local web UI, and gives you an interactive environment to test them. You can chat with an agent, inspect its reasoning steps, and iterate quickly with hot-reloading.

GitHub: https://github.com/orlevii/agent-playbook

Right now it supports agents built with pydantic-ai, which I’ve been using heavily and found easy to work with. I’m planning to expand support based on what people find useful, so feedback is especially welcome.

This is the first public release, and I'd love feedback on the core idea, the developer experience, and any feature ideas that would make it more useful. Happy to answer questions!

Thanks for taking a look.

This was shared the other day and sounds exactly like what you want. Throw in Steam cloud syncing (although I'm not certain RetroArch supports that) and I imagine it's about as hassle-free as can be. Possibly even more hassle-free than the original consoles - no blowing into cartridges here!

A lot of display hardware uses a combination of spatial and temporal dithering these days. You can see it sometimes if you look up close, it appears as very faint flickering "snow" (the kind you'd see on old analog TV). Ironically, making this kind of dithering even less perceivable may turn out to be the foremost benefit of high pixel resolutions (beyond 1080p) and refresh rates (beyond 120Hz) since it seems that raising those specs is easier than directly improving color depth in hardware.

> I was surprised to see that they weren't like, say, 20 years behind or something

That actually says more about what the Western "First World" media feeds their people, that the rest of the world is 20 years behind and stuff :')

Maybe 10, maybe some places, sure. In terms of social progress and basic rights, hell there are places that are 50 or even 200 years behind (see Afghanistan's treatment of women for example)

But tech-wise, I was surprised when I visited some parts of the Middle East and Asia; almost everything was available online, paid for electronically, clean and effective mass transport, walkable and safe cities..

This. Absolutely this. It is complete bonkers to suggest that game devs dictate consumer hardware, insane to run the asylum.

All game development should follow Nintendo model: there’s a fixed hardware and game devs should go out of their way to optimize to the spec, not consumer shelling out thousands every years because someone can’t be bothered to optimize their cashgrab.

I dunno, man. You get to work for months to completion on a deeply fulfilling project, get well compensated, and then the plug gets pulled before it goes to production? That's living the software engineering dream!

Jokes aside, the article resonated with me (before the LLM vibes got overpowering) as I am learning Irish as my own personal challenge, which as a minority language is similarly derided by some as useless (there is essentialy no Irish speaker that does not also speak English) but which I have found tremendously intellectually invigorating and the most pumped I have been for a project in a long while. So it rang true for me before half way through a distinct "linkedin parable" nature started to come to fore. So alas I rather doubt the author is learning Sumerian at all. Cynical perhaps.
by vidarh | 2025-11-14 11:07:09+00:00
That's categorically not true, as long as there's a human reviewer at the end of the chain. It can usually continue to deliver actual improvements over several iterations (just like a human would).

That does not mean you can get away with not reviewing it. But you can most certainly with substantial benefit defer reviewing it until an AI review thinks the code doesn't need further refinement. It probably still does need refinement despite the AI's say so - and sometimes it needs throwing away -, but it's also highly likely in my experience to need less, and take less time to review.

No cliche at all - I'm in the same boat, showing my stuff online was way out of my comfort zone!

I was postponing proper, dedicated performance testing for some time and would really love to up my game in that regard.

I'm very happy with pgTAP approach of running stuff in transaction and rolling them back after the test - how this works in RegreSQL?

Would love to provide feedback and test the hooks when you will be working on them. I'm mostly interested in performance testing and my use case would be to run them on CI and compare to previous metrics stored somewhere in order to fail CI when performance regressions are introduced.

Happy to connect, got contact info in my profile.

No, because that's not what the definition of novelization is. By novelization i mean when someone makes a novel version of a movie.

The point im trying to make here is we regularly expect translations from one medium to another to be copyrighted, so why is this different?

No, because i believe it to be a pretty text book example of fair use.

Interesting article! One thing that made me literally LOL was the fact that several exploits were enabled via a Google "style recommendation" that caused on-heap length fields to be signed and thus subject to sign-extension attacks.

The conversation-leading-up-to-that played out a bit like this in my head:

Google Engineer #1: Hey, shouldn't that length field be unsigned? Not like a negative value ever makes sense there?

GE#2: Style guide says no

GE#1: Yeah, but that could easily be exploited, right?

GE#2: Maybe, but at least I won't get dinged on code review: my metrics are already really lagging this quarter

GE#1: Good point! In fact, I'll pre-prepare an emergency patch for that whole thing, as my team lead indicated I've been a bit slow on the turnaround lately...

Rust forces you to consider things upfront, or to put it another way, a C developer does what the borrow checker does manually. Sometimes, they do it after asan/ubsan/tsan has reported the issue. Sometimes it's after a segfault. Usually it's after the user hits the bug already.

Nix similarly forced issues to be reasoned with upfront.

I really appreciate your wisdom hidden in this long thread embedded in a promotional post.

A lot of things changed between your last reply. I left the enterprise potholes and rabbit holes. (Ironically I got that job via a HN hire thread three years ago. I was very lucky to have a manager who would hire someone like me.)

Now I am relieved to explore what I see on the horizon. The first thing I did was going to the Apple Store to buy a latest M5 MacBook Pro with the highest 24G memory and get MLX running.

It was surprisingly good.

Now I am watching all the vibe coding videos by Andrej Karpathy and see what the trendy kids are doing.

Then I will sit down and walk through all the NN and LLM papers, dive deep to MLX, and imagine what Alan Turing would do if he had my M5.

No more rabbit holes and potholes.

Hardly a surprise, given the nature of Spark and benchmark prerequisites. Comparing a positively ancient distributed JVM-based compute framework running on a single node, with modern native tools like DuckDB or Polars, and all that on a select from a single table- does it tell us something new?

Even Trino runs circles around Spark, with some heavier jobs simply not completing in Spark at all (total data size up to a single PB, with about 10TB of RAM available for compute), and Trino isn't known for its extreme performance. StarRocks is noticeably faster still, so I wouldn't right off distributed compute just yet- at least for some applications.

And even then, performance isn't the most important criterion for an analytics tool choice- more probably depends on the integrations, access control, security, ease of extendability, maintenance, scaling, support by existing instruments. Boring enterprise stuff, sure, but for those older frameworks it's all either readily available, or can be quickly added with little experience (writing a java plugin for Trino is as easy as it gets).

With Duckdb or Polars (if used as a basis for a datalake/house etc) it may degrade into an entire team of engineers wasting resources on implementing the tooling around the tooling instead of providing something actually useful for the business

Guardrails for anything versatile might be trivial on consideration.

As a kid I read some Asimov books where he laid out the "3 laws of robotics", first law being a robot must not harm a human. And in the same story a character gave the example of a malicious human instructing Robot A prepare a toxic solution "for science", dismissing Robot A, then having Eobot B unsuspectingly serve the "drink" to a victim. Presto, a robot killing a human. The parallel to malicious use of LLMs has been haunting me for ages.

But here's the kicker, Iirc, Asimov wasn't even really talking about robots. His point was how hard it is to align humans, for even perfectly morally upright humans to avoid being used to harm others.

Yeah it's so sparse on actual details of Sumerian or cuneiform that after reading the article I remain unconvinced the "author" either cares for or knows anything about the topic.

(To be clear I know nothing about it either, but as a human with some similarly "pointless" hobbies, I can't imagine posting a writeup with so much motivational bullshit but so little about the actual thing I'm interested in.)
