I haven't spent a ton of time in New York, don't know how bad things get. So grain of salt here. But I really dislike enclosing spaces. So much modern policy is about adding constraints, safety safety safety, and it all feels bad to me.

As a bicyclist, I liked sharing the street more than I like being in a narrow dedicated bike lane, because the street was open & I could see clearly & now I'm between parked cars (with some pedestrians loading/unloading) and a sidewalk with pedestrians who sometimes go onto the path. Intersections are much harder to feel safe on, because now there are separate flows of traffic that re-encounter each other & have to figure stuff out. I just feel trapped and corralled. I loved being out and about.

We're talking about adding huge fences to some of our bridges for suicide prevention. Beautiful spaces with gorgeous overlook. I feel a profound sense of loss that again we are corraling ourselves in, tightening one of the few open spaces around us.

It's a bit daunting to me reimagining the subway, imagining it being a much more closed in confined system. The subway is such an interesting mix of busy platform and space, a juxtaposition, and it feels like we'd be losing that. We'd be losing openness and space. Losing sign of the trains themselves again doesn't seem like it matters deeply, is crucial, but it still makes me profoundly sad to imagine. More like an elevator than a train, solely an interior space, man elevating beyond the built environment into an abstracter form of infrastructure they cannot even see.

I recognize good motives for all these things, recognize the cause. But I don't feel like there's recognition back, I don't feel like anyone else is out there advocating for open, for space. Civilization accrues, taking bits and pieces of the public space with it as the stuff builds up and the space gets retooled; that seems to be the direction of things. I feel so alone in caring for & loving openness, want so badly to see some weight given against walling ourselves in. Downvoted already, yeah thanks.
very cool. Are there libraries like these that do whole characters with bodies?
Would love to play with those!
This sounds like some drug hysteria, IMO. Until I see some independent lab results showing human bone is it I remain doubtful.

According to the AFP Fact Check Department, it's probably not true. I would say it's probably a blend of what they can get their hands on & mix up a batch of various synthetic chemicals.

I don't know if this is still the case, but in the 90s, on the street "wet" marijuana, which was marijuana laced with PCP, was rumored to contain formaldehyde/embalming fluid as kind of a hype/sales tactic. I'd suspect that's the case here as well.

No but Google (for example) recommends fine-tuning based on at least 500 examples of question response pairs. DPO as far as I know requires a good and bad example. It's not a technique based on just saying "ai response is bad".
This is complete insanity that vertical task bar is still not implemented, pretty much what OS has to do - manage memory, manage processes/threads, manage windows to enable smooth UX with multiple programs. It more and more fails on the last one. Seems the policies have changed to drop support for everything that is used for example less than 1% of users, (just neglecting 10 million users, costing likely billions $ time and sweat for those users, nbd). Even if it would cost MS like tow part time developers time/money.

It is such a neccessary multitasking functionality on work environments that I'm quite lost when Win 10 support ends and the alternative taskbar tools do not work reliably then. Small hope that Windows 12 or whatever comes next would be the better one.
I didn't try to "moralize out of this", apart from the condemnation of many types of personal liability people will find themselves on the receiving end of based on simply owning real estate? That could certainly stand to be reformed, but the criticism is aimed at the prevailing laws rather than the insurance companies for working with them.

Personally my gripe is that I wish insurance companies would update what are seemingly quite obtuse pricing models, rather than pushing customers into invasive surveillance tech. For example I'd appreciate if it were possible to raise my deductibles by an order of magnitude and see a meaningful drop in premiums. But instead it seems like the only coverage knob that has an effect is the max coverage limit (which when you think about it, actually shouldn't even be a thing. the whole point of insurance is to cover the long tail risk). My gripe is a little more pronounced for auto, where I quoted out dropping the miles driven on one vehicle to nearly zero and it reduced premium by a mere 10%.

Re minor claims, maybe I'm underestimating how much future premiums went up after those somewhat frivolous homeowners claims I mentioned, and they effectively just ended up forming loans rather than affecting the overall expected value of losses.

Anecdotally, anyone who rides will you tell you this. It doesn’t matter how high your high viz vest is, or how loudly you rev your bike, someone will blindly cut you off and not realise you’re there until it’s way too late.

I’m glad to see the data to back that up. Maybe now my fellow riders can agree that their motorbikes are a bit too damn loud, and tone it down.

Big kudos for building things from scratch. Even though it's not directly applicable in most jobs, the knowledge you have from understanding the entire "stack" helps a lot when using tools and frameworks, because you understand their value and cost.
> If at some point we see a need to create more incentives for people to reproduce, that sounds fime to me

Population is declining in about half of the world countries, see that table: https://en.wikipedia.org/wiki/List_of_countries_by_total_fer... Among them are very developed and rich countries: South Korea, Japan, Germany, Norway, Switzerland, Australia.

In most of these countries, governments realized long ago that rapid population decline is bad for the economy. In some of them like Japan, governments started implementing various incentives decades ago. As you see from the numbers in that table, these incentives didn’t work.

To me this seems punk and glitch, but not brutalist.

Arguably HN is already pretty brutalist. As a second exemplar, I consider https://brutaldon.org pretty brutalist.

It seems plausible that you can't be brutalist and be inaccessible without javascript enabled.

It seems plausible that themes are the antithesis of brutalism. The point is to show the underlying structure. Not to add pretend structure.
There is a hidden speedup in Japanese in that words are kept short by reusing them for many meanings: it has an astonishing number of homonyms. The words are distinguished in spellings (like different combinations of kanji and kana) but to a much lesser extent in spoken language (all you have is pitch accent; but there are many homonyms that are the same down to pitch accent).

Japanese printed dictionaries are ordered by the kana expansion of a word, so you can see the homonyms together.

Pretty much on every page of a Japanese dictionary, you can spot some runs of homonyms or near homonyms.

Sometimes it's like clusters of 9 words or even more (Of course, not equally frequent: say only maybe two, of those will be in frequent usage.)

Also, informal Japanese will be even faster, by dropping various repeated formalities that add syllables in every sentence.

On the HDMI-to-USB front, beware of dongles that oversell themselves.

A blue USB connector just means a blue USB connector, it doesn't necessarily mean it's USB 3.0 (they might use weasel words like "USB 3.0 compatible").

Most have an integrated scaler, e.g. will accept 4K input even if they only capture at 1080p - the listing will likely emphasize the former rather than the later.

The MS2109 chip will do 1080p at 30fps, over USB 2.0 (mjpeg).

The MS2130 chip will do 4K at 30fps (mjpeg), or 1080p at 60fps (yuv), over USB 3.0.

Tell: Thunderbird just made me lose a contract
So I have been a long time fan of Thunderbird mail client.

But today, I just realized a sad event that made me lose an email that was buried in a thread.

I had an email thread started a week ago. I sent, they replied, then I replied back.

They were supposed to reply within a day or two. I didn't get any, or Thunderbird made me believe so.

I was waiting and waiting even checking in the junk.

Nothing new, nothing unread, the thread is still all read.

Eventually, I learned that they have been replying and Thunderbird has been burying it under the thread. No way to find out.

Looked up in the bugzilla, and it is a known issue.

So if any of you use this client I suggest you to check deep within threads. Don't expect to see it at the top of the thread, or for the thread activated to be unread like Gmail and others, even outlook.

End of rant.
thank you and ok, I see you argument. I am astonished that such poor countries are counted as developed. I am asking myself how bad are non developed countries.
You may have better luck if you specify what low budget means to you. The latest iPhone Pro is better than some of the entry level cameras, especially if you weren't planning to splurge for a nice prime lens.

I think the cheapest you should go is the Sony EV-10 plus Sigma 16mm 1.4 lens. If those are more than you want to spend, stick with your phone camera because you won't see enough improvement to make it worthwhile.

In either case, watch some YouTube videos about podcast lighting because that will matter more than your camera.

Insurance has always been a negative-EV trade for the average person

Negative EV in terms of dollars, but not necessarily utility. For most people, a 1% chance of losing their $500k home is worse than paying a $5100 premium.

Think about what exactly? Nobody's gonna afford to spend money to buy perpetual licenses for a games that will be on shelves only a few years. What exactly do you expect they do better?

Nobody's breaking existing copies.
If motorcycles require loud pipes to be safe, they should probably be banned altogether - but I don't really think it is necessary to have loud pipes.
> LA should be the perfect city for mass transit, heck it was in the 1920s and 30s

In 1920, the population of LA was less than 600,000 (https://www.laalmanac.com/population/po02.php), and the built up area was a lot smaller (https://lamag.com/lahistory/citydig-this-1929-map-tracks-l-a...)

I guess its population density also was quite a bit higher, making it harder to serve the population well with public transport using vehicles that can transport many people at a time.

> Show me on the map where we would put the lines without displacing thousands of people

Having said that, mass transit includes buses. There are zillions of roads in LA. On the main roads dedicate one lane in each direction to buses or, better, light rail.

Main problem will be how people would get to stations. You could change one lane on minor roads to a bidirectional bike lane, but such bike lanes would not only be unattractive to ride on, but also dangerous because they’d frequently cross huge roads. So, I don’t think that would solve this problem well enough.
Excited to try this out later. Starred. Thank you!

Ask HN: SQLite in Production?
I am using it for a small app, and the latency is so low that it feels like the app is like 10x faster than if it was running Postgresql. Now of course scaling will not be the same, but still.

Are any of using SQLite in production and if so what have your experience been with it? Hit any limits?

Yes, so the insurance company should underwrite your roof for a fixed cost (adjusted for inflation) on your home. After 20 years of paying into that pool they shouldn't be able to just drop you now that your roof is old and pocket all the money and walk away and leave you with a roof that needs replacement.

What I'd expect is that you pay into the pool and then after 20 years you've more than paid for the new roof and so you get a new roof.

It should be slightly stochastic financing of your new roof and since a roof has a finite lifetime there should be a new roof at the end of it. It shouldn't be "hey, looks like your roof is about to have issues now, and we only insure new roofs, thanks for the profits, byeeeeee...."
That’s only true if Aurora is the most valuable thing that developer could be working on.
Some Sony cameras support acting as webcams natively over USB now too, so you can skip the HDMI step. Not sure about which specific models though
Bullshit. Liability and regulation can absolutely help with ensuring better practices. The fact that the SEC now requires disclosure of active breaches has forced companies overnight to begin taking cybersecurity seriously, and there are plenty of other liability related changes happening as we speak.
I don't think it has anything to do with your eyes being open/closed, or even to do with your eyes at all, unless it's describing something different to what I assume. It's about mental images and visualization, not your field of vision itself.
This would have been witty IMO: "the paper will be out in O(negative_peer_reviews)"

> (an) author here: paper will likely be coming out in O(month)

Ug. I'm adding "O(month)" to my list of bootless metaphors.

Why? (1) Because in Big-O notation, O(month) would equal O(day), which is not the intended meaning in the comment above; (2) It is non-sensical; one would never say e.g. "the run-time of an algorithm is O(seconds)" -- we write some kind of input inside the parens, not the output

Anyhow, we already have the words roughly and about; e.g. "about a month".

Feel free to call me pedantic, but words matter.

> they should be self-consistent with no surprises

And LLMs are exactly what is needed - they know the consistent and no-surprise answer to anything. The UI will adapt to serve your needs, that's how it can help you. The web we see today is full of dark UI patterns and junk content. A generative UI could filter, rank and present the pile of garbage in a clean form.

Social networks and big website operators control what we see, in what order we see it, and how it is presented. All of them carry vectors of attack. They abuse the public. For example FB was always changing where it put various user settings, and resetting them from time to time.

An AI agent that creates a generative UI can guard your preferences. I see these gen-UI agents as running locally in privacy. They interface with the web to interact and gather information, and distill it into bespoke UIs. They overrule all the power games publishers played with users and try to prevent users inadvertently leaking private information, an AI firewall, especially needed now that the web will be filled with synthetic text and other AI agents. Few people will still look at the raw web, we will wear a protective mask of gen-UI.
This is not about improving your experience. This is about getting end users to behave a certain way. If you have a gambling or trading app, you could automatically adjust the UI based on your end users psychological/behavioral profile, gradually over time, to put the more profitable/higher risk option in more prominent/more likely to be used positions. Or maybe your user clicks "block access" by muscle memory and your AI based predictor finds out that if they replace the block button with the allow button users now click allow way more. Big success. I can't wait to see how much more value we can extract from people by controlling their behavior through UIs.

Worked with a PhD student who had an algorithm to tell airline pilots exactly when to turn their engines on. Probably saves more pollution than I or my descendants will generate in all of our lives so I feel I’m comfortably in the black there.
IANAL, but in the US, it depends on whether could have reasonably expected that their stuff was hidden. If your roof is sloped so that a person on the street could get the same information by walking around the block, then aerial surveillance is just a faster way to get that public observation.

In contrast, if you set up a high fence around your pool in order to sunbathe naked, aerial photography would probably be an invasion of your privacy? If your roof was designed in a similar way, one might be able to argue it was wrong for the company to observe aspects of it without permission. (Although they might have gotten permission via the insurance contract...)

I think this legal standard becomes tricky (or at least ought to receive more scrutiny) when we start talking about pervasiveness and permanence. Just because I know that an arbitrary person might take a picture of me in public doesn't mean I expect every single thing I do outside to be recorded forever by a technological invisible stalker hovering over my shoulder at every outdoor moment.

I did a quick comparison on MNIST with a small ConvNet, comparing this AdamWSCheduleFree optimizer against a few other optimizers (RAdam, NAdam, AdamW, SGD, Adam, Adafactor, SophiaG). The validation accuracy seems to be okay and the train loss decreases remarkably quickly.

Validation accuracy: https://i.imgur.com/8ZtX7Rd.png

Train loss: https://i.imgur.com/o5XdQ29.png

Code: https://bpa.st/NVJQ (currently only runs on my computer, but not enough time to clean it up)

Note that this is just a toy benchmark with very little hyperparameter tuning. You could probably get similar results with most optimizers and an appropriate schedule. Nevertheless, I appreciate every hyperparameter that I do not have to set manually.

In summary, this seems to be a promising optimizer. I'll add it to my list of optimizers to try for new deep learning projects.
What would it even mean to accept an arbitrary message? All you can do in that case is record and/or forward because the contents are unknown.
Lots of reasons I suppose. Outside script-kiddying with mergekit it takes some serious knowledge to properly train anything, and expensive amounts of compute to actually do it or even run it in the end. It's not the most accesible thing.

For classical methods once you got the algorithm nailed, it will work 100% of the time. For probabilistic methods, you do get better results most of the time but they can also screw up randomly for no reason so their deployability in production is hell on wheels. It's infuriating at times.

Still can't argue against it being very fascinating.

Yes. Similar to being a young person trying to establish a credit history, if there is little to no info to go on companies will tend to assume the worst about your riskiness and charge accordingly.
That's a really interesting mix of wild claims and plain wrong statements.
It's also gotten very poor at exact text matches. I often make a bet to myself before searching for certain things as to whether or not Google will show something irrelevant. Most recently I was searching for a specific memory address error crashing ASIO. I was using the exact text from the error popup, and Google was giving me results for... Skyrim Script Extender refusing to start. The only shared text was "Page fault" between the two. I've also noticed this when looking for specific part numbers where instead it will give me magazines by matching the ISSN. Forcing quotes is a dice roll, as sometimes that will just return zero results, or Google will do the exact opposite and broaden the search terms.
