> Yes, you do need to check if both records are written and then report it back to the client. But that is a non-fsync request and does not tax your system the same as fsync writes.

What mechanism can be used to check that the writes are complete if not fsync (or adjacent fdatasync)? What specific io_uring operation or system call?

I owned a 3310. I remember going into the mountains for a week and didn’t even charge the phone beforehand, because the battery would last anyway. Back then I used to climb, and I remember how it fell out of my pocket from around 30m (100 feet). When I got down, I just picked it up from the ground and put the back panel back on. The phone worked perfectly for at years after that.

Tesla has to create new revenue sources. The Supercharger moat is evaporating. Elon is otherwise pretty successful in torching the brand loyalty. Regardless of one's personal opinion, Tesla owners as a whole are at odds with Elon politically. Tesla owners skewed educated, living in blue states and are environmentally conscious. I think this will go down as one of the biggest self-owns in history.

The only thing preventing Tesla from going bankrupt is trade barriers on Chinese EVs.

Elon has always been a snake oil salesman and I suspect this robotaxi venture will blow up in his face in a way that's potentially fatal for Tesla. All it will take is someone to be killed in or by a robotaxi. That'll bring in the authorities and likely reveal what a shitshow it is behind the scenes.

The USA is not a democracy, it is a constitutional republic. The architects of the system were highly suspicious of Athenian democracy and the tyranny of the majority.

Third parties don't really work in this system. If a third party gains transaction on an issue, one of the two main parties will largely adopt those policies. Otherwise, the 3rd party just splits the vote and the party least like the third party wins.

Everything is always changing too. Both parties have changed quite a lot in even the last 10 years.

Even further back look at an election map of JFK and Nixon in 1960. The states have practically all flipped. California and the west coast voted all Republican. The southern states voted all Democrat.

I wasn't clear by grouping a subjective and a (supposed) objective opinion. I mean:

- I'd give 6/10 to the regular nugget's taste, and 6/10 to the beyond meat (sorry for typo in precedent post).

- BM and regular are both highly processed food. 22 ingredients for the regular (not even counting "spices extracts"): https://www.mcdonalds.com/content/dam/sites/ch/nfl/pdf/2023_...

Agree, the quality part of the book is hard to grasp. I get that some written works are good and some are bad, that it is hard to qualify why yet there is a general consensus around it but I haven't been able to distill any deeper meaning than that.

However, the discussions regarding "gumption" and separating abstractions from reality when needed (i.e. "the carburetor set screw") as well as several other great lessons from the book have really helped me fine-tune my thinking. I think reading this a few times in your 20s is a fantastic time investment.

From the title I was hoping this would be a survey of databases using io_uring, since there've been quips on the internet (here, twitter, etc) that no one uses io_uring in production. In my brief search TigerBeetle (and maybe Turso's Limbo) was the only database in production that I remember doing io_uring (by default). Some other databases had it as an option but didn't seem to default to it.

If anyone else feels like doing this survey and publishing the results I'd love to see it.

I got rejected from the lottery once! It was a while ago, at that time I had about 40% chance to "win" it.

I suppose folks from India and China make up the bulk of the applicants, and a high percentage of the people who end up getting the visas.

My life could have been completely different if I did get an H-1B. Oh for the path not taken.

I hope there is someone who received it in my stead, who now is wonderfully happy and successful in the US.

That's not the right way to look at it.

Just because I went vegan doesn't mean I hate the taste of meat. I love the taste of meat. I sometimes treat myself to products that taste like meat.

There is no "final stage veganism" for me where I hold my fingers together in the "X" shape towards anything that reminds me of animal-based foods. And a lot of people seem to think this caricature is realistic based on the amount of times people think they're trolling me on Twitter by posting an image of a sizzling steak.

A lot of people are really bad at change. See: immigration. Short of giving everyone jazz improv lessons at school, there's nothing to be done.

To be fair, change is not always good. We still haven't fixed fitness/obesity issues caused (partly) by the invention of the car, 150 years later. I think there's a decent chance LLMs will have the same effect on the brain.

This just doesn’t line up with the reality I see. I just went grocery shopping yesterday (at a bog-standard suburban grocer), and the meat section was like 20x bigger than the tofu/alternatives section. Same at Costco - they’ve got like 4-5 tofu/alternative products in total, and multiple aisles full of meat products. (And Costco doesn’t cary things that “nobody is buying”.)

> Major compilers used to not be free. Major IDEs used to not be free.

There were and are a lot of non-free ones, but since the 1990s, GCC and interpreted languages and Linux and Emacs and Eclipse and a bunch of kinda-IDEs were all free, and now VS Code is one of the highest marketshare IDEs, and those are all free. Also, the most used and learned programming language is JS, which doesn't need compilers in the first place.

Lots of change in elevation, with steep hills, stairs etc. For comparison my resting heart rate is ~57 on average, and for more intense workouts I can go up to ~160 for periods of time, so I think my range is healthy. But I can get a lot out of a brisk walk in this terrain ;) I've found it's a lot better for my knees than running or jogging, which I've practically replaced in favor of mountain hiking and said brisk walks, as well as indoor cycling when the weather is bad.

Lovely post @antirez. I like the idea that LLMs should be directly accessing my codebase and there should be no agents in between. Basically no software that filters what the LLM sees.

That said, are there tools that make going through a codebase easier for LLMs? I guess tools like Claude Code simply grep through the codebase and find out what Claude needs. Is that good enough or are there tools which keep a much more thorough view of the codebase?
by antirez | 2025-07-20 15:25:17+00:00
It’s not that bad: K2 and DeepSeek R1 are at the level of frontier models of one year ago (K2 may be even better: I have enough experience only with V3/R1). We will see more coming since LLMs are incredibly costly to train but very simple in their essence (it’s like if their fundamental mechanic is built in the physical nature of the computation itself) so the barrier to entry is large but not insurmountable.

Yeah...look at all the top researchers in AI, and count how many of them came here through H-1B. Gotta be something like 70%-80%.

Nothing against "homegrown" talent, but let's be real - US is getting cream of the crop talent from other countries.

(And that's just AI, not do the same for other fields. Many of these people started as regular engineers and devs., and didn't come to the through the EB-1B/Einstein visa. Just a regular H-1B. And many on student visas.)

There’s something so amusing about the way AIs screw up but still just take full accountability for their actions.

> Cars are becoming prohibitively expensive

This isn’t true. There are dozens of car models near $20k today, and most of the base model inexpensive cars in the US have always cost around today’s $20k-$30k in adjusted dollars. Even the Ford model T: https://www.investopedia.com/financial-edge/0512/how-inflati...

Quality of cars today is unquestionably better, and the number of features and conveniences is unquestionably higher. Cars last longer than they used to, a lot longer on average. There’s ample stats on this.

The average price of cars has gone up slowly relative to inflation because there are now better cars to choose from, and people choose to pay more. But you can’t even buy something as bad as a 1930s or 1950s or 1980s car today, and you can get a much better car now for less money than you could then.

“The fact that they’re hiding data should tell you everything you need to know. If you really want trust, you have to have full transparency.”

Anything Musk says is simply not trustworthy.

Not just my opinion but proven over and over again.

Hiding safety data is just icing on a cake that he has been baking for years. The real problem here is that those who choose to trust him and his companies are putting others at risk.

Those who own/drive a Tesla typically have insurance but what about those who hire robotaxis? Can they be held personally liable when their roboride hurts someone?

> But database engines are absolutely the target of io_uring's feature set and they're expected to be managing this complexity.

io_uring includes an fsync opcode (with range support). When folks talk about fsync generally here, they're not saying the io_uring is unusable, they're saying that they'd expect the fsync to be used whether it's via the io_uring opcode, the system call, or some other mechanism yet to be created.

Has someone computed/estimated what is at cost $$$ value of utilizing these models at full tilt: several messages per minute and at least 500,000 token context windows? What we need is a wikipedia like effort to support something truly open and continually improving in its quality.

Beyond is hard to buy in supermarkets too. Whole Foods doesn't stock it at all and many others never have it in store even if the chain does technically stock it online. I just want it because it's 0 cholesterol and tastes the same as meat to me.

This is probably the cause of their problems. You need to be one of the big food brands to have leverage to get it on shelves in a prominent position and they are small.

Just thinking aloud: I've been in this industry for what will be going on 20 years now (startup/tech/venture funded stuff) - my observation is that things have become incredibly abstract over the past 15 years - people are very abstracted away from what they are really doing...in that, the capital is increasingly abstracted far far away from capital providers, capital allocators are increasingly abstracted away from the outcomes of the capital they allocate, and capital deployers are increasingly abstracted away from society at large. I do occasionally still run into people who I think "this is a fully formed sensible thoughtful responsible human" - but it's incredibly few and far between - I think the reason is primarily how decoupled everything in the system has become from it's upstream and downstream effects. The other consequence of this is that the competitive nature of market dynamics shift, things become hyper competitive because the unknowns become deeper. The inevitable geometry of large, scaled systems.

I'm not even sure that's it's a desire for greater prosperity, honestly. I think it's most about enforcing social hierarchy by race and gender and parentage, though people vary a lot on what they want the hierarchy to be based on. This is a huge change from past visions for America, and will lead to far less prosperity, inevitably. The fight against DEI, policies meant to maximize corporate success by taking the best talent no matter race or gender, is clear indication of that. And there was plenty of indication that companies that used ESG in running their companies overperformed, yet there was a huge revolt against that.

It's more about the density of hipsters than Londoners per se. Lots of Londoners go to Canvey Island for a holiday, but you probably won't get oat milk there, because it's not that kind of Londoner. Bristol and the West Country are crawling with their own local hipsters.

Counterquestions

- What living creature is using wheels to move around?

- What kind of birds come strapped with a jet engine?

Sometimes non-natural solutions are easier and often better than attempt to replicate nature for every cost. Imagine your logic applied on a plane - birds flap their wings, thus this 737 should spread it wings and flap away like a goose. Now take military goose and flap fast enough to get supersonic...

Even if we were not past a hard takeoff point where AIs could decide for themselves what to work on, the things that would be created in all areas would be incredible.

Consider every time you played a game and thought it would be better if it had x,y, or z. Or you wished an application had this one simple nrw feature.

All those things would be possible to make. A lot of people will discover why their idea was a bad idea. Some will discover their idea was great, some will erroneously think their bad idea is great.

We will be inundated with the creation of those good and bad ideas. Some people will have ideas on how to manage that flood of new creations, and create tools to help out, some of those tools will be good and some of them will be bad, there will be a period of churn where finding the good and ignoring the bad is difficult, a badly made curator might make bad ideas linger.

That's just in the domain of games and applications. If AI could manage that level of complexity, you can ask it to develop and test just about any software idea you have.

I barely go a day without thinking of something that I could spend months of development time on.

Some idle thoughts that such a model could develop and test.

Can you make a transformer that instead of linear space V modifiers it instead used geodesics? Is it better? Would it better support scalable V values?

Can you train a model to identify which layer is the likely next layer purely based upon the input given to that layer? If it only occasionally gets it wrong does the model perform better if you give the input to the layer that the predictor thought was the next layer. Can you induce looping/skipping layers this way?

If you train a model with the layers in a round robin ordering on every input, do the layers regress to a mean generic layer form, or do they develop into a general information improver that works purely by the context of the input.

What if you did every layer on a round robin twice, so that every layer was guaranteed to be followed by any of the other layers at least once?

Given you can quadruple the parameters of a model without changing it's behavour using the Wn + Randomn, Wn - Randomn trick, can you distill a model To .25 size then quadruple to make a model to retain the size but takes further learning better, broadening parameter use.

Can any of these ideas be combined with the ones above?

Imagine instead of having these idle ideas, you could direct an AI to implement them and report back to you the results.

Even if 99.99% of the ideas are failures, there could be massive advances from the fraction that remains.

I do have a project that's been running about 25-years. But it's not static - new features are added, bugs are fixed, and it just keeps going. Some of the code and the overall architecture are original but there's plenty of new.

That said though, the vast majority of projects I've been on are probably no longer in existence. This is why I take a more casual approach to most projects - I see it as somewhat temporary and it doesn't make sense to put so much effort into a clean project.

https://usafacts.org/articles/federal-farm-subsidies-what-da...

Subsidies go mostly to corn and soybeans. Think those are multipurpose but corn is used to feed livestock, of course. 10 or 15% may be a lot in a low-margin industry, and I don't know how it's split among crops.

No all subsidies are direct. For example, water costs too little in Arizona so foreign companies grow feed stock there to ship home.

The difference is that it used to be combined with some pretty cool stuff. He was a loudmouth jackass but he was (running companies that were) doing neat things with electric cars and rockets. Now the cars and rockets are stagnant, his newer ventures are jokes, he blew up Twitter, and is making a decent attempt at wrecking the country I call home. The loudmouth jackassery was kind of amusing when there was cool stuff to go along with it. Not so much anymore.

yeah, this weird.

You need to be catastrophically bad to mess something like htmx.

If you are doing things like eCommerce, form heavy, read heavy, websites (the majority) instead of full apps like a paint/game/code editor (that I say should start with htmx and small components with whatever), htmx IS so simple.

What kind of messy backend this projects have that failed it? Because this is the point: htmx is just html with a bit of more interactivity.

To fail with htmx then you MUST has failed to render html well, and if that is the case, with react will be even worst.

An outcome like this suggest that if the project were made in react or similar it will have failed even harder

Terminal with vim in one side, the official web interface of the model in the other side. The pbcopy utility to pass stuff in the clipboard. I believe models should be used in their native interface as when there are other layers sometimes the model served is not exactly the same, other times it misbehaves because of RAG and in general no exact control of the context window.

HTMX uses HTML snippets over the wire to replace HTML elements on the client. It's not supposed to grow to support every use case you can imagine.

If you're calling APIs that you have no control over, you do so on your server.

That's the entire point of HTMX: the minimal necessary addition to browsers/HTML to allow HTML REST APIs to update pages without full page loads.

Those top tier researchers are the kind of people the program is legitimately meant for, but for every one of those there are probably 10 or 100 H-1B contractors being paid below-market wages resulting in underemployment of US citizens, especially early career graduates.

The program is also used to employ people that won’t quit when they are mistreated because their family’s existence in the country depends on continued employment.

Missing from the article — which is funny, considering it's written from the perspective of a university student — is how deliberate Sun’s academic strategy was. In 1998 they launched the "Authorized Academic Java Campus" program, licensing Java tech to universities and setting up official training centers. Even before that, they were offering Java tools free to schools for teaching and research.

Combined with a massive branding push — Sun doubled its ad spend from 1995 to 1997 — Java ended up everywhere in CS education. By the late ’90s, first-year courses using Java weren’t a coincidence; they were the result of a planned, top-down push.

Hate these burgers. As a dairy-loving vegetarian, first the vegans came along and ruined everything by evicting most of the tasty options from restaurants, and then the meat eaters somehow wanted vegan food that tasted of animals and that became the default option on many menus. Vegetarians (who I grant you are difficult to pity as the centrists of the food world) got utterly screwed.

It’s a massive cultural difference. I’ve much preferred the individuals who chose to live in NYC as they seem to be a much more outgoing, social, welcoming, and open type of person. The type of individuals that go to SV and are from these two countries seem the complete opposite.

We’re coming up on 50 years for Space Invaders. We can say that it’s endured because:

- it’s self-contained: it works without dependencies, and with the hardware it was designed for

- there’s an ongoing need: peope want to continue playing Space Invaders

- it’s transposable: the environment it runs in can be recreated through additional layers (emulators here)

- it’s recreatable: the core concepts behind Space Invaders can be reimplemented in the prevailing contexts of the time
