> The fact that almost no one on this [thread] knows these

Its not that they aren't known, but rather we just came off a long trend of thin-clients and cloud storage. Some companies merely stay in that ethereal space, while others had concerns about their data. Criticizing people for doing what experts were pushing for the past 20 years doesn't need to devolve into calling their expertise into question.

The downvotes are for that, not because "you're wrong".

NVMe hungers, keeping it fed is hard work. Doing some serial read, decompress, checksum, write loop will leave if starved (QD<1) whenever you're doing anything but the last step. Disk IO isn't async unless you use io_uring (well ok, writeback caches can be). So threads are almost a must to keep NVMe busy. Conversely, waiting for blocking IO (e.g. directory enumeration) will keep your CPU starved. Here too the answer is more threads.

You don't have any recourse, at least not under American law. This a textbook third-party doctrine case: American law and precedent is unambiguous that once you voluntarily give your data to a third party-- e.g. when you sent it to OpenAI-- it's not yours anymore and you have no reasonable expectation of privacy about it. Probably people are going to respond to this with a bunch of exceptions, but those exceptions all have to be enumerated and granted specifically with new laws; they don't exist by default, and don't exist for OpenAI.

Like it or not, the judge's ruling sits comfortably within the framework of US law as it exists at present: since there's no reasonable expectation of privacy for chat logs sent to OpenAI, there's nothing to weigh against the competing interest of the active NYT case.

That's exactly the point of remote syncing: whatever changes to code you make locally are nearly instantly available on a remote machine, so you can compile and run your software on a production-like machine. By "supports all tools" I mean that you can run whatever you like on your source code locally, whether it runs through emacs or not, and the result is available remotely. And with bidirectional syncing the reverse is true too.

This sounds suspiciously like that idea that Alexa would make sense because people would order shit from Amazon through voice based assistant.

I seriously doubt the vast majority of people would trust actual purchases to LLM agents that have the inherent feature of being possibly very inaccurate. If I have to review my orders, I would rather do those actions myself than having the extra step of having agents do it on my behalf.

> Why did it take an insane person

I think the mark of political insanity is labeling someone "insane" simply because you apparently partially disagree with them.

> but I give him no credit

So you're not interested in solving the actual problem in favor of ensuring your preconceived ideas are never changed?

> instead I blame previous administrations

Yea I can't imagine the type of person they would have been pandering to. :|

I think Lex is prepping his interviews very well. He will ask questions that address the areas in which the interviewee is an expert in. However, you begin to realize that he often struggles to ask follow-up questions that are relevant to what the interviewee has shared on various topics.

This differs in other podcasts. For example, Sean Carroll, a theoretical physicist, conducts interviews with colleagues, who are also theoretical physicists. This enables him to engage in a meaningful conversation with the person being interviewed. When both parties strive to use language that a wider audience can understand, it truly becomes enjoyable.

Question you and do research on you on the open web as well as on whatever other data they can access / request. You can get selected for some form of in-depth questioning and research on you at a border for many reasons. At that point, it's certainly still possible that they miss some information about you but in times of big data collection by governments, "better" systems to make sense of the data and permissive legislation, it becomes less likely. Especially if you did not prepare in advance (for example: most people who post some hateful or threatful shit probably do not take the greatest care possible to make themselves as untraceable as possible).

I once got detained for about four hours or so at my destination airport. There were multiple rounds of questioning by persons who seemed rather intelligent and based on what they asked, they did some research about me in the meantime (or wanted to achieve that effect - no idea what tactics those people use). There could have been a few reasons why I was questioned in-depth - maybe it was because of a random spot check, maybe because they considered some stuff in my luggage unusual, maybe because I had work affiliations with people who are routinely questioned when entering some countries due to their work. Who knows.

This was many years ago, so I assume they had to do a lot of their research by hand and there would have been limited other data sources available. I imagine this is rather different today.

You are right. Its not the job of the committee to support anything. They just have to vote on proposals.

Imagine Linux devs would start worrying about what "C standard" wants xD.

In my industry (gamedev), folks never needed to worry about how non-standard our code is either. As long as it ships on relevant half-dozen platforms and gets job done, its fine. One does not get a Boy scout badge for being standard compliant.
Show HN: OVR, a framework for streaming HTML with AsyncGenerator JSX
by robinoross | 2025-06-23 19:07:44+00:00
If you are looking for a nice way to stream HTML with JSX, ovr v4 has just been released.

ovr optimizes Time-To-First-Byte by evaluating components in parallel and streaming HTML as it becomes available. It sends partial content immediately rather than waiting for all async components to resolve, enabling browsers to start parsing and loading assets sooner.

This architecture provides true streaming server-side rendering with progressive HTML delivery - no hydration bundles, no buffering, just HTML sent in order as ready.

New in version 4: ovr now includes helpers to simplify route management. You can define Get and Post routes in separate modules with built-in Anchor, Button, and Form components that automatically keep your links and forms synchronized with route patterns.

There is no thermal mass. It's almost pure vacuum but the handful of particles that are out there are whizzing around at high energies that make them very hot.

Interesting to think that while it's not a concern to Voyager at its pokey 17km/second, a true interstellar ship traveling at some respectable fraction of C would compress the diffuse interstellar gasses enough to make them a potential hazard. You frequently see people saying stuff like "if we could accelerate to a high fraction of C you could get anywhere in the galaxy in a single lifetime", but it may not be so simple.

I'm especially annoyed at the electrical equipment category. 20 years ago it would be hard to find even a power strip or AC adapter for sale in America that wasn't UL listed. Even dollar store merchandise usually had the label.

Today, you can only buy two kinds of such products: The (I assume Alibaba-sourced) Amazon Marketplace, fulfilled by Amazon items which are never UL listed, and brand-name items from a brick and mortar store, which cost 8x the price of the equivalent 'Amazon special.'

I know "UL" is just a label and that not having it doesn't necessarily prove anything, but absent any form of certification, an device on Amazon Marketplace may come from a vendor that has literally never even submitted a sample for quality testing to anyone. BigClive on YouTube has shown some shocking (literally) teardowns.

I've heard that insurance companies will deny a claim if your house burns down due to a non-UL-listed device causing a fire. Terrifying.

I found out recently that Samsung Galaxy devices (in this case A24 with One UI 7 + Android 15) were installing apps silently from Galaxy Store — without user consent.

This wasn’t from Play Store or APKs. The apps showed up post-update even with all permissions disabled. I investigated and traced it to a specific hidden toggle inside Galaxy Store settings. Video includes proof + how to disable it step-by-step. Curious if anyone else has seen this behavior, and whether it happens on other One UI devices

Using your system instructions for uv for every LLM now since first seeing your post last year, thanks! It's insanely helpful just asking e.g. Claude to give me a python script for XYZ and just using "uv run". I also added:

If you need to run these scripts, use "uv run script-name.py". It will automatically install the dependencies. Stdlibs don't need to be specified in the dependencies array.

since e.g. Cursor often gets confued because the dependencies are not installed and it doesn't know how to start the script. The last sentence is for when LLMs get confused and want to add "json" for example to the dependency array.

Lumping all artificial dyes together is a sign the regulations RFK Jr. is proposing or implementing are unscientific. These are different chemicals, and actual scientific or medical arguments would treat them as such.

There's plenty of good discussion possible about which additives in food should be regulated more. But making this kind of unscientific push is harmful in the end.

I disagree on two counts:

- having Colin stop by your thread is strictly an opportunity for useful information to flow from a singular source to many people

- you would hear that aloud 100 times a day in any office where serious work was being done by professionals on a deadline and think nothing of it, bet your ass places in the world where serious hackers rise only on merit and have the best gear embargoed are saying stuff like that all the time. this nepotism capture bubble is an outlier in the history of serious engineering.

Defining the rudeness threshold down to the point where cperciva clears it is one part comedy and two parts tragedy with the words Hacker News in bold at the top of the page.

I think this is just half true.

When dealing with purely high-level code (including C without inline assembly), the compiler doesn't need a discrete assembler. This much is true, and most modern compilers will not spit out assembly unless requested.

However, there's usually still a stage of the compilation process where an assembly-like internal representation is used. Once the compiler has chosen which registers to use and where, and which instructions to use and in what order, etc., it's close to machine code but not fully there yet. At this point, jump targets will still be labels without concrete addresses, instructions will be still be referenced by mnemonic, etc.

Serializing this internal representation as assembly will generally produce more readable code than disassembling the final binary. So it's not assembly exactly, but it's pretty close.

I do have a compliance need, similar to this office i imagine.

Teams is more secure in my opinion.

I as an admin can control who you can/can't talk to, what you can share with them, when you can share it. Correctly configured MS Teams is a pretty secure setup.

On the flipside im not sure i can make someone else's Whatsapp not auto download anything sent to it.... The two apps aren't really comparable unless I've missed an entire 'Whatapps for government/enterprise' business arm.

Nuclear power is very feasible in space. Perhaps you're overlooking that radiated power scales with the quartic of absolute temperature (T⁴); it's not difficult at all to radiate heat from a hot object, as it is for a room-temperature one.

(How hot? I won't quote a number, but space nuclear reactors are generally engineered around molten metals).

Such papers aren't worth much. For example, that meta-review claims masks work. Some other scientists did a different meta-review (the A122 Cochrane Review) that concluded the opposite (strictly speaking, that there was no useful evidence masks worked). If you dig into the details of why they disagree, you'll find none of the studies claiming this stuff works are scientifically valid whilst the Cochrane meta-review is very careful. Real-world reliable evidence > models.

So what happened: activists went directly to the head of Cochrane and demanded the review be disowned, which it was, despite it having been signed off on by the org previously and there being no scientific problems identified with the study. That's how they manufacture consensus in the healthcare system: top down orders from corrupt leaders who suppress beliefs and evidence that makes them look bad. They do this because it works. After all, look at this thread. People say, look at all the evidence! Look at the consensus! They can't all be wrong!

Yet a system that concludes both yes and no simultaneously isn't worth anything. The institutions of science failed during COVID, and frankly are failing most of the time hence the replication crisis. It's not specific to masks or social distancing. We can play that game for any claim you want to make about COVID, or many other topics. Science is broken.

> explain ... evidence that standing close to someone is equal risk to standing further away from them?

There are two components to this:

1. There's a threshold value beyond which a non-immune person becomes infected and that viral load in the exposure over that doesn't matter much. Given that viruses replicate that's not surprising.

2. That a sick person can emit infectious aerosols that can hang around in the air for long periods and travel long distances e.g. via air ducts.

The intuition you're working from is that SARS-CoV-2 viruses are created in the body, that they travel only in large droplets that fall to the ground quickly due to gravity, and that risk of infection is linear in dose. Thus, being far away from an infected person should reduce the risk linearly. That's the idea the "professionals" used to justify their policies, but it's based on a model that's too far from reality to be useful. It might work for a hypothetical spherical-cow type person standing on a perfectly empty and flat 2D plane, with no air movements. It doesn't work for real world scenarios with complex layouts and complex movements of people, which is why when you look at the behavior of the virus in real settings like the Diamond Princess or jet liners the results are completely different to what the model would predict.

The "judge" here is actually a magistrate whose term expires in less than a year.[1]

Last time I saw such weak decision-making from a magistrate I was pleased to see they were not renewed, and I hope the same for this individual.

Yes, actual progress in meaningful operating system changes in terms of how one might write a program, or access fundamentals like identity, have really stagnated in terms of making their way down to end users.

We have high-concept things like Urbit that wanted to remake identity and secure communication that are utterly inaccessible to most savvy folks, never mind average end users. And in the meantime we're shipping entire Unix environments around inside OCI images to make up for the lack of consistency and portability on the backend.

Regular users are left with a tragedy of the commons as paid/saas programs support integrations with other specific paid products instead of with general open standards that could foster more diversity and interoperability. Everything is tacked on at the application layer - imagine going back to the folks who designed Kerberos decades ago and telling them that bouncing the browser back and forth between websites is what we settled on!

I like the new transparent theme, but yeah, it's just a GUI theme. Bring me back a consistent GUI where I can get themes from a modding community that apply to every app on the system and give me control over my look and feel! Instead, we get Wayland and a loss of 90% of the classic Linux desktop software. Bring me an OS that I can seamlessly deploy in a near-stateless/immutable fashion everywhere without falling into the trap of Nix! Instead, we get yet another rewrite of the fuckin' Ubuntu installer that still doesn't make the resulting system any more appealing for someone who would administer a corporate fleet of Linux workstations.

There are a lot of flaws but here's the most glaring: They looked at three genes to determine whether DHEA-S affects longevity in men. But the problem is that the genes they tracked as markers for DHEA-S are also involved in lots of other stuff!

rs45446698 (CYP3A7) is also associated with testosterone, height, BMI, bone density, C‑reactive protein, estrogen, and urate. It's also heavily involved in the metabolism of drugs and exogenous chemicals in infants and neonates; it's not as widely expressed in adults: https://en.wikipedia.org/wiki/CYP3A7

rs615567 (FGF9) is associated with bone development, vision traits, blood pressure, and cardiovascular disease. Also lots of other stuff: https://en.wikipedia.org/wiki/FGF9

rs36155566 (MCM9) is a member of the mini-chromosome maintenance (MCM) protein family, and it's involved in various processes related to cell division. Reviewed here: https://www.sciencedirect.com/science/article/pii/S258900422...

These are ultra-pleiotropic genes. They do a lot. You'd be hard-pressed to pick worse genes as yardsticks. (Maybe CYP3A4, lol.)

So you simply can't look at those three -- which together explain just ~1% of DHEA-S variance -- and pin anything on DHEA-S! They didn't even attempt to measure DHEA-S in their larger cohort to bolster their findings. It's really shoddy.

The rules for what locations/checks can be reached in what situations and with what items are painstakingly encoded in a machine readable format: https://github.com/OoTRandomizer/OoT-Randomizer/tree/Dev/dat...

I don't know the specifics of the OoTR algorithm but in general they work by considering a set of items which are currently "available", and then progressively picking a random item to place only in locations which are reachable with that current set of available items (which is expanded with each placement).

It's great that we're still getting data from these two probes 50 years later but it absolutely sucks that these are the only 2 probes we have out there. How long can they keep running, another 5 or 10 years max? It's already considered an engineering miracle that they are still going.

What of people growing up 10, 20, 30 years from now? They'll be taught in school about stuff from Voyager and then told 'and that was what we learned in the golden age of space exploration, which ended long before you were born because we couldn't be bothered to keep at it.' Having grown up in the 70s, I feel somewhat betrayed that we just just gave up on doing moon stuff, rendering a whole generation's aspirations on space exploration into a lie. The claims that 'there is nothing more to discover up/out there' is nonsense, much like the claims that 'chips can't be made any smaller' that I would hear back in the 32nm period.

The lack of long-term commitment to exploratory space is a terrible waste. To be sure we have been doing some stuff in system, but if he had kept putting out deep space probes every few years with more advanced instruments we would have learned a lot of other things by now, and we would have a long-term stream of new data coming in for the future. Now arguments for launching more deep space probes are dismissed with 'it'll take decades before we get anything useful back.' Yeah, because we stopped iterating! Meantime allowing that sort of exploration to become anachronistic is one reason we are overrun with flat-earthers and other science woo even at the highest levels of government.

I think the big value add of Mojo is that you are no longer writing GPU code that only runs on one particular GPU architecture.

In the same way that LLVM allows CPU code to target more than one CPU architecture, MLIR/Mojo allows GPU code to target multiple vendor's GPUs.

There is some effort required to write the backend for a new GPU architecture, and Lattner has discussed it taking about two months for them to bring up H100 support.

I mean thinking about students as actors of pure bad faith, a student could easily copy and paste any instructions given to them into a LLM and bypass any required training data. Even if an AI company respects the license and the source does not end up in the training set, model knowledge tends to be generalizable to a given area. The only way I could see making a language that is intentionally obtuse to write in (brainfuck or really any other esolang seems to work), but that fails at being a good introductory programming language.

As I said, I’m pretty sure that number is wrong by a little. And does 76 mean January or December? That’s a long time for small children. This thread is about people announcing things and then taking a while to do them. But we were in a town hit particularly hard by a recession. I have no doubt they were turning inventory closer to the Best By date than yours was. I bet all those sales I remembered seeing (3 for a dollar!) were overstock.

it is not strange that these systems don’t do incremental compiles? Things are literally paged.. Why does newer systems such as typst do full compiles when a single page is edited? I know that all subsequent pages might be affected, but surely, one could workaround this by allowing sloppy but fast compile options for subsequent pages, that sacrifices correct layout for something decent?

That's a complete, total waste of studio monitors. Monitors are for nearfield positioned listening. Sound great when you are in the (small) sweet spot, but generic and flat off axis, which you will be most of the time in a workspace like a kitchen. And a kitchen is a terrible place to seriously listen to music, with all of the hard tile surfaces and tinny sheet metal appliances reverberating. You may care very much about sound, but you don't know very much about sound. If you did, and you wanted good sound while working in the kitchen, you'd be wearing some nice open back headphones, not some fairly cheap, very small monitors.
