There are more ways to find them. Look up Z score. TL; DR New detectors can discriminate water from explosives. Old ones couldn’t. None of them are doing IR spectroscopy.
I, like most people I know, buy Android devices around the 300 euro limit, use them until they break for whatever reason, which is measured in years.
The only apps that get installed nowadays are the ones that must be for a specific service, or gaming.
Many people even turn updates off due to the way companies get creative changing the application on every update.
In the old days before the iOS/Android duopoly there were no updates at all, and the few times they happened to be supported, it required the developer SDK to update the firmware.
Outside communities like HN, regular people hardly care about updates.
They still need to land on consumer PC shops for regular users to take notice, until the trend of online only, and zero OEM support, rather reverse engineering even when there are systems out there like Dell XPS, Windows and macOS will keep being what most regular users buy.
Either that or a mix of tablets with detachable keyboards or Chromebooks, none of them GNU/Linux powered.

If you take age out of the equation, is there supposed to be something wrong with preferring to hire people who are willing to work longer for less pay over people who aren't willing to work as long who want more pay?

To be honest I didn't find the historical parallels as convincing in this article. I'm glad the author did recognize that we are in uncharted waters, but I think another potential reason to believe that our current fascist government is a little bit more restrained than earlier ones is due to the same forces that allowed it to rise in the first place - that is, social media and instantly viral videos.
What has happened since the Alex Pretti shooting was simply impossible in previous fascist governments. The administration can tell all the lies they want about it, but most of us have eyeballs, and we can see the multiple videos with frame-by-frame analysis. In the past, government propaganda would have been more effective in cases like this - it would have been a case of "who do you believe, team A or team B?" I don't have to believe either team, I just have to believe my own eyes.
I see the low-code tools still all over the place, now they also do agentic AI.
I read the whole thing and you are smoking crack. They are calling for the overthrow of the Islamic regime and (explicitly) for the death of the supreme leader. As far as their theoretical argument goes, it's that the masses in IRan are ready to have a revolution but that they lack the organizational skills and roadmaps that communists beleieve themselves to have. They also argue that external support of a revolution is strategically bad because the incumbent regime will use it to portray the Iranian students/working class as tools of foriegn powers.
> You're orders of magnitude more likely to die in a road accident, but people don't fear that. They fear terrorist attacks far more.
This can be traced to people in a car believe they can control whether they have an accident or not (and largely can). In an airplane, however, you have no control whatsoever.
Maybe they think it'll work better since it penetrates deeper than vaseline.
Historically, oppression was attention-limited. The spies and goons couldn't monitor everybody. Now, they can.

The fact that Greeks and Romans had weightlifting and boxing gyms for their athletes in no way makes it a "bit of a myth" that people used to get strong naturally by doing physical labor. For example, average grip strength of people under age 30 in the US has declined markedly just since 1985.

The reason there is no unringing this bell is not just that we have a capricious, vainglorious president, it's that all of checks and balances that are supposed to restrain the executive have proven worthless so far. Republicans in Congress have completely declared their impotence, having fully relinquished their duties that the Constitution specifically delegates to the legislative branch, like tariff power, war powers, etc.

Amazing and possibly related:
I'm incredibly confused. The HN title is totally different from the article title, the article doesn't even contain the word "autosave" anywhere.
Autosave is usually associated with something like Microsoft Word.
As far as I can tell, this is about a JavaScript library for restoring HTML form values if something goes wrong. OK, sure that's a form of autosave.
But then the HN title is "autosave is not recovery" which... huh? Isn't the article saying it is for recovery?
Also, the article is a bunch of confusing philosophizing and doesn't really explain anything at all. The linked GitHub repo at the end is infinitely more informative:
Lubricant analysis is a commonly available service. It's normally done on lubricating oil for large engines (heavy trucks, locomotives, ships) as a diagnostic tool. The usual tests are mostly to see what properties of the oil or engine are degrading. Full analysis of new oil to validate that it conforms to specification is available.[1]
Hydrocarbons are rather well studied.
I think "theft recovery" is probably meant.

You're not even telling a coherent story at this point. The "cold winter theory" isn't merely that the populations are different (though: again: when you look at the molecular evidence and the way genes propagate, it's nowhere nearly as clear as you'd think), it's that the cold winter populations are smarter. But you have to literally ignore most of human history to reach that conclusion. Somehow, in this view of the world, evolution only kicked in a couple hundred years ago. Seems unlikely!
And MS is on the verge of adopting the penguin completely. They are currently still in the "extend" stage.

The “Iranians that you work with” in the west are highly self-selecting. They’re like Cubans in Florida or Vietnamese—people who fled in the aftermath of the revolution and are extremely antagonistic towards the regime. My family left Bangladesh the year after the dictator made Islam the official religion. My dad is apoplectic about the Islamist parties being unbanned recently after the government was overthrown. By contrast many of my extended family, who came much later for economic reasons, are happy about that. The people who disliked the Islamization of the country and had the financial means to do so left while the people who were fine with it stayed.
My daughter’s hair stylist is Iranian (she was an accountant in old country). When Jimmy Carter’s wife died, she said “I’m happy she’s dead.” I’ve never seen anyone else say a negative thing about the Carters personally. Even die hard Republicans who think he was a weak President don’t hate him as a person. But this is not an uncommon sentiment among the Iranian diaspora.

I've never succeeded on getting a refund with Google. There were a few apps that tricked me into buying a subscription (namely Musescore and Yazio), I immediately asked Google for a refund because I didn't actually get what I thought I was getting, and they denied me both times.
Now I just don't buy anything on the Play store that I can't afford to just be outright scammed on.
Not quite the original, but this has the links to the papers as well as commentary on why it's important:
Real life ain't abstract math. You have MSDS 'mulmen mentioned, but I also can't imagine any factory being able to just mix shipments of ingredients "A", "B", "C", etc. without the actual content being documented on purchase orders, OSHA reviews, etc. You may want to operate in secret, but at the very least, the taxman really wants to know if you aren't skimping on your dues, so there should be plenty of relevant documents in circulation.
Of course they do: Youtube makes Google more money. Video is a crap medium for most of the results to my queries and yet it is usually by far the biggest chunk of the results. Then you get the (very often comically wrong) AI results and then finally some web page links. The really odd thing is that Google has a 'video' search facility, if I want a video as the result I would use that instead or I would use the 'video' keyword.
The invention of the "airplane" is just a simplified term for "controlled and sustained powered flight".
Which the Wrights did with both controlled and powered in the 1903 Flyer.
(The Wrights invented the first 3-axis control system, and designed & built the first aviation engine capable of sustained flight.)
While the Wrights were first, by several years, its invention was inevitable.

Here's the one-minute version from the FAA.[1]
Runway overrun areas marked with diagonal stripes have an Engineered Materials Arresting System. There are several different materials used. One is pumice embedded in styrofoam, with a thin concrete layer on top. Large aircraft weigh enough to break through, and the pumice is crushed to powder, absorbing energy. This yields a surprisingly short stopping distance. The aircraft landing gear will be damaged, but the rest of the aircraft is usually intact. The overrun material comes in prebuilt blocks, and after an overrun, only the ones damaged need to be replaced.
It gets a lot of use. The FAA has logged 25 overruns stopped by EMAS, out of 161 runway ends so equipped. That's surprisingly high.
It's a simple, clever system.
It did compile - the coding agents were compiling it constantly.
It didn't have correctly configured GitHub Actions so the CI build was broken.
It‘s not a priority for Microsoft, it‘s intrusive and above all it‘s shit.
When I worked at Boeing, I talked about autoland systems with my lead engineer. He said the autoland was too perfect, as the airplanes would touch down at the same place every time.
This caused that place in the runway to suffer severe fatigue damage.
Right, so that was exactly what I was thinking when I wrote that. All three of Flash, PDF, and the browser DOM are expansive, ambitious metaformats, containers for every piece of technology that has ever had a bug.
Your take on why Flash didn't survive is more cynical than mine. I genuinely think Apple threw up their hands at the prospect of attempting to solve a security problem on the same scale as the browser itself (something it took them a long time to get a handle on --- along with everyone else --- even after they put the kibosh on Flash).
They should be! I think this is going to be a pretty transformational couple years for IT. To be honest, I've spent a bunch of my career being kind of skeptical about IT (software developer chauvinism), and I think the rug is getting pulled out from under that mentality.
When you start of with 'a stupid question' and people then give you lots of reasonable answers and you persist with more such questions at some point you cause me to doubt if you were really asking your first question in good faith.
You should go build that site! It's exactly what HN isn't.
The easy fix is to let go of the unsiloed concept and to add a couple (<10) main subjects and an 'all' page. That way whoever wants to can discuss what they want and flags can go back to their original meaning.

On the one hand, it's fascinating to know just how much of what shapes our lives was already there a hundred years ago in some form.
On the other hand, it's just as fascinating to realize that all that, and ~everything that shapes modern life, did not exist until ~200 years ago. Not just appliances, but medicines and medicine, plastics and greases and other products of petrochemical industry and everything built on top of it, paints and cleaners and materials and so on...
I see the basic problem as "plastic monomers cost about 50 cents a pound." Exxon-Mobil is happy for chemical recycling systems to break plastics down to "a mix of chemicals you might find in the BTX section of a chemical factory" because those all cost about... 50 cents a pound and are interchangable from that point of view.
Landfilling costs maybe 2 cents a pound, any kind of recycling scheme chemical or mechanical has a hard time beating that.
That said there is some market for mechanical recycling. I've got some nice garmets made from recycled PET bottles, I think the feel of the polyester is better than average. That's no "circular economy" however. In New York you can find PET bottles for Pepsi and Coke company beverages but I know some people who are afraid these will shed more microplastics than virgin bottles.
That must be some extension you have installed. I don't see it.

This is interesting. John Logie Baird did in fact demonstrate something that looked like TV, but the technology was a dead end.

Not everyone is optimizing for total comp. Some are optimizing for better lives. It's not a wild concept considering how many people get pulled into startups, 90% of which fail, under the guide of "mission" and lower market comp.

Certainly, there is a minority of folks making wild comp at FAANG, but that is a privileged minority of total tech and IT workers.

The Great Lakes have a management principle that is basically "You can use the water of the Great Lakes by permission as long as the water remains in the watershed." And permission is not automatic either.
The reason for that to a large degree is that the Great Lakes area looked over at the Southwest, which wasn't even as bad at the time as it is now, did some math, and worked out that if the Great Lakes tried to supply the Southwest that it would cause noticeable dropping of the water level. I'm sure it would be even more dropping now.
The problem is, the Great Lakes aren't just some big lakes with juicy fresh water that can be spent as desired. They are also international shipping lanes. They make it so that de facto Detroit, Chicago, and a whole bunch of other cities and places are ocean ports. Ocean ports are very, very valuable. There are also numerous other port facilities all along the great lakes, often relatively in the middle of nowhere but doing something economically significant. This is maintained by very, very large and continual dredging operations to keep these lanes open. Dropping the water levels would destroy these ports and make the dredging operations go from expensive to impossible.
So, getting large quantities of water out of the Great Lakes to go somewhere isn't just a matter of "the people who control it don't want to do that", which is still true, and a big obstacle on its own. The Southwest when asking for that water is also asking multiple major international ports to just stop being major international ports. That's not going to happen.
The point is you can't say "an expert finds x useful in their field y" and expect it to always mean "any random idiot will find x useful in field y".
That's true of exercise in general. It's bullshit make-work we do to stay fit, because we've decoupled individual survival from hard physical labor, so it doesn't happen "by itself" anymore. A blessing and a curse.
I remember reading about a metal shop class, where the instructor started out by giving each student a block of metal, and a file. The student had to file an end wrench out of the block. Upon successful completion, then the student would move on to learning about the machine tools.
The idea was to develop a feel for cutting metal, and to better understand what the machine tools were doing.

Apple AirTag is one of those interesting products that you don’t think you need until you use it. An Apple thing that just works as advertised and is cheap enough that you can keep picking them up at Airports, without the guilty feeling that usually comes with buying high-priced Apple products, such as the Polishing Cloth. And when you order it online, the nice engravings are fun for my daughters. They like it when it is pinged, finding their toys and bags, and it is worth the price tag.
I had to put in a few of my daughter’s pencil pouches and some toys; they are cheaper than the AirTags and, financially, make no sense to lose an AirTag that costs more than the items being tracked. But hey, daughter is happy, and that covers up for the cost.

"why go to the shed"
A good question but there's a good answer: Debugged and tested code.
And by that, I mean the FULL spectrum of debugging and testing. Not just unit tests, not even just integration tests, but, is there a user that found this useful? At all? How many users? How many use cases? How hard has it been subjected to the blows of the real world?
As AI makes some of the other issues less important, the ones that remain become more important. It is completely impossible to ask an LLM to produce a code base that has been used by millions of people for five years. Such things will still have value.
The idea that the near-future is an AI powered wonderland of everyone getting custom bespoke code that does exactly what they want and everything is peachy is overlooking this problem. Even a (weakly) superhuman AI can't necessarily anticipate what the real world may do to a code base. Even if I can get an AI to make a bespoke photo editor, someone else's AI photo editor that has seen millions of person-years of usage is going to have advantages over my custom one that was just born.
Of course not all code is like this. There is a lot of low-consequence, one-off code, with all the properties we're familiar with on that front, like, there are no security issues because only I will run this, bugs are of no consequence because it's only ever going to be run across this exact data set that never exposes them (e.g., the vast, vast array of bash scripts that will technically do something wrong with spaces in filenames but ran just fine because there weren't any). LLMs are great for that and unquestionably will get better.
However there will still be great value in software that has been tested from top to bottom, for suitability, for solving the problem, not just raw basic unit tests but for surviving contact with the real world for millions/billions/trillions of hours. In fact the value of this may even go up in a world suddenly oversupplied with the little stuff. You can get a custom hammer but you can't get a custom hammer that has been tested in the fire of extensive real-world use, by definition.

Afaiu protocol buffers are very popular for over the wire communication and in that use case cap'n proto does not win you much @ performance (?).
And if you don't go over the wire the performance difference might not matter for many use cases (e.g there is plenty of json sent around as well) and when it does matter: cap'n proto or something custom w/ desired performance characteristics other than protocol buffers is chosen but here cap'n proto covers a slim middleground (?).
+ usual adoption dynamics: protocol buffers have more mindshare and if another solution is not clearly way better for the use case: switching/trialing is not happening as much. (?)
> Could America engineer an aquaduct from the great lakes to california?
Why would the midwestern states consent to that? The southwest is structurally unsustainable. If we can’t develop sufficient renewable energy to power desalination, we’ll probably have to abandon much of California.
My prediction is that if we ever have another civil war, it will be states going to war over access to water.
Little by little, eventually it won't be different from many other regimes.
I like how it (afaiu) leaves my codex config alone (meaning when I start codex the usual way I have the usual settings but when I launch it via ollama I get the model from ollama).
That said: many open weight models, while quite capable are not a great 1:1 fit for each agent harness and it's not easy to figure out if it is an issue with the model, model size, quantization, inference parameters or something else or a combination.
So for me it is a bit frustrating to pinpoint if a 'bad' experience is just 1 simple change away from a great experience.
For ollama specifically: make sure in settings you have set the context window size to something around 64k or 128k.
The default is 4k which is not enough for agent workflows. I have set it to 256k initially but that then was too much apparently (maybe i need more RAM).
Also it is possible that you have to restart ollama once you have changed the context window size or once you have downloaded the model (?).
Also check if the model you want to use is a good fit for your RAM, if in doubt pick a smaller model first.

generative ai increases ambition, lowers barriers
more open source, better open source
perhaps also more forking (not only absolute but also relative)

I'm fairly optimistic that generative ai is good for open source and the commons
what I'm also seeing is open source projects that had not so great ergonomics or user interfaces in general are now getting better thanks to generative ai
this might be the most directly noticeable change for users of niche open source
Since Android has 70% of the world market share, and there are countries where iOS is hardly a presence other than the country's elite population, those are quite a few customers they will be missing on.
