Not impressed with the LLM hype or whatever latest crypto token you're hockin'

It largely works and it's a massive business success.

You can make anything work when you have enough money to buy and radically change the entire runtime you’re relying on.

One must suspect that if they did not have insane amounts of money to burn, they could have tried other approaches to fixing the problems. Maybe engineering, perhaps.

Maybe you think this is a witty comment, but ironically it illustrates exactly the problem with outsourcing your thinking to a machine. All they needed to do was raise the instance limit, which they immediately did when they saw the surge of traffic.

No expensive tokens needed, no agents needed, no outsourcing their work to some calculator. The problem was solved even faster than an LLM would have, and they maintained full control and understanding of their systems while solving the problem. It's almost like human expertise is great.

And you know, the whole "maybe ask AI thing" is exactly what everyone is making fun of. Any engineer worth their salt should be able to look at a system crashing under heavy load and come up with a few proper solutions to the problem that don't involve "ask ChatGPT", but people have completely replaced their thinking with this "I'll just ask the calculator" laziness. It's sad, pathetic to see really.

Regardless of what they were doing before, it seems they are doing the right thing now.

Regardless of the fact that they were stealing and uploading user secrets, they changed their behavior after they got caught, so let’s ignore what they did in the past.

That said, I find it odd that people assume that reading a book is always higher quality than reading the internet etc. - many books are pretty low quality.

I don't think it's really about the quality, I think the difference is that with a book there's no easy next tab to switch to when a sentence or passage gets too long and loses your interest. Even if a book is poorly written, it will still require you to either fully focus for the duration - or put it down. There's no convenient "leave the tab open in the background and switch to something else for 30 seconds" for books like there is with the internet.

You should try getting your news from somewhere other than X and Fox.

You know, I actually suspect musk is much worse that what has been reported, especially given his involvement with Epstein and those other creeps, but I moderated my post to only confirmed and broadly reported facts.

These things are all built on the back of stolen content, and they guy running X is a notoriously corrupt billionaire who recently ran an illegal effort to strip food and medical aid from third world countries which has already resulted in hundreds of thousands of deaths.

I don’t understand why anyone would be surprised that they’re also stealing code from their users. Pay attention to what people like Musk do to those under their power. He will do the same to you in a heartbeat.

any time any agent confidently asserts something then it has to provide associated evidence

And this is enforced by... another LLM? Seems like it would work alright until something is asserted implicitly and not categorized as an assertion.

Oh so you do get it! All these idiots running around acting like a calculator can think. The bus is really going to hurt when they hit 40 and realize they outsourced all their humanity to a machine. Art, writing, even reading - these dorks hand it all over to chatGPT. Then they go online and act like they’re more productive than ever, when all they can produce is a dribbling stream of liquid shit.

The fact that you don't know whether you're talking to an LLM or a human right now is good enough for me.

Uh huh. So you have no evidence, and can't prove shit. That's what I figured.

LLMs are nothing but a shallow mirror of human thought, they don't hold up to any serious examination and the only people who think they do are typically narcissists who can't form deep connections with real people. The superficiality of LLMs is not apparent to these fans, because they have never managed to connect with the depth and inner world of another human.

I don't think people sit around going "Grrrr who can I ban next?". Instead this stuff gets noticed because you see the webserver at 99% CPU utilization for 2 days straight, check the logs, and see you are somehow getting crawled by half the IPs in New York City.

Simulated intelligence is now known, thanks to LLMs, to be indistinguishable from real intelligence.

Oooff, that's quite the claim. Why don't you try to back it up? Cite some research.

Last time I checked it was still very possible to distinguish "reasoning" LLMs from Real People.

I’ve been scraping dating sites and feeding them to ChatGPT, and it’s amazing how few of the profiles still say anything about the person.

Yeah, it's common knowledge now that you can't put many identifying details into a dating profile - there are creeps out there doing things like harvesting them and feeding them into ChatGPT.

It’s just an example of the fact that programming is far more than code. It is also managing dependencies, build systems, making architectural decisions, developer support, etc.

It is very possible to be good at slinging code and bad at everything that is required to support deployed code.

Based on geohotz history, I wouldn’t be surprised if he falls in that bucket - hacking and algorithm skills are great but don’t lend themselves at all to building twitter. That’s why it is foolish to pretend like one guy is great or even good at everything.

Have you just discovered the concept that humans are all humans, and all our achievements are just a mountain of knowledge we stand upon, from first principles?

Humans are human, someone being born in Africa doesn't magically mean that they will never understand technology.

We dug holes and filled them with broken glass and fire to practice. 18 of us died in the process.

Is it providing material aid to terrorists to point out that maybe a hole filled with water would have been a better practice environment?

Threads generally have less memory overhead and context switching between them is theoretically faster, but as I suspect you know it is situational and not as simple as just s/process/thread/g. There are many tradeoffs, including the loss of memory isolation, and since Postgres is a network application which holds a rather important position in most architectures, proper memory isolation is very important.

Switching to threads doesn't guarantee weaker isolation, just like it doesn't guarantee better performance, but those nuances are why "switching to threading yields performance improvements" is over simplified to the point of uselessness. It simply reeks of the same kind of ignorance that used to drive statements like "rust doesn't have vulnerabilities" and "rewrite it in javascript for web scale performance".

Ah yeah, what I figured. You clearly have no idea what you're talking about. Don't get all mad when someone calls you out on it.

By the way, just so you have some concept of what the actual problem is despite your resistance to education:

Simply switching from processes to threads will not yield the claimed performance increases. A 300x improvement on analytic workflows? From a direct transliteration? Your BS alarms should be going off. They should be screaming "5 Alarm Fire".

The only way they got that increase was by breaking the synchronization mechanisms that provide ACID guarantees in Postgres, otherwise a direct rewrite would expect very similar performance.
