One of my mentees worked with Xata in their app using Prisma and it wasn't great. The need for a second db for the 'shadow' db that prisma needs, and they would throw Out of Memory errors frequently without any significant usage.

The app now moved to Prisma's postgres hosting and it works like a charm, only thing that changed is the db.

"A shared cultural experience means there are people in it who don't like it or don't engage with it"

You just disagreed with yourself, the kids on america can relate to kids that live on middle east and asia

if this not shared cultural experience, then idk what else is because original post mention that most people on his hometown aware of song that got played, not every hometown on america have same experience

> I wish they were sold in a store that I could just walk into and try them for a minute.

I've constantly wondered why this doesn't really exist. Not even just with AR or VR but with lots of products. I thought that early on in the transition to more online purchasing that it was well understood that people were still visiting stores so that they can inspect items before purchase. There always seemed to be a weird perverse incentive where for a given store their online prices would be cheaper than those in store. Combined with wider selection of sizes and styles, it felt weird not to buy online, especially if you were not in a major city. Employees would even tell you this! Themselves being unable to just handle the "online" sale for you (baffling...). Malls offered a lot more business value than just facilitating direct purchases. They do a lot to build brands, loyalty, and advertise to customers.

Being a lanky kinda guy I could never find clothes in my sizes in store but it was still quite helpful to see the difference between certain materials and would often lead to buying a more expensive version than another. Without the stores, it just seems to make a market of lemons[0], and I think that's kinda apt given general consumer frustration. You can't rely on reviews and you can't rely on images or even product descriptions...

How the fuck am I supposed to know what I'm buying?

My hypothesis is that some bean counters saw that sales were plummeting in stores and concluded that they should then close them. Having the inability to recognize that the purpose of the store had changed, despite them likely using the stores in the new fashion themselves. Hard to make effective decisions if the only viewpoint you have is that of a spreadsheet...

It’s because you’re looking at it from opposing ends.

From the perspective of the data source, in a streaming context, the size is finite — it’s whatever you’re sending. From the data sink’s perspective, it’s unknown how many records are going to get sent in total.

Vice versa, in a batch context, the data source has no idea how many records will eventually be requested, but the data sink knows exactly the size of the request.

That is, whoever is initiating the job knows what’s up, and whoever is targeted just has to deal with it.

But generally I believe the norm is to discuss from the sink’s perspective, because the main interesting problem is when the sink has to deal with infinity (streaming). When then source deals with infinity (batch), it’s fairly straightforward to manage — refuse requests of too large a size and move on. The data isn’t going anywhere, so the sink can fix itself and re-request. You do that with streaming and data starts getting lost

Agreed! But, again, I ask who is going to work these jobs if Americans have said they don’t want to? The labor market has been propped up by immigrants for the last half decade, and this admin is not friendly to immigrants. There are already not enough Americans who will work the manufacturing jobs that exist today (or the jobs going unfilled are outcompeted by higher wage service work).

Americans are cosplaying, they are not serious in this regard. If they were, they would be filling these jobs they say are so desperately needed, and manufacturers would pay whatever market clearing wage is required to fill said jobs. If they wanted good paying jobs today, they’d unionize. Way easier than waiting for manufacturing to come back (which will take years, if at all) and maybe have a shot at one of the few manufacturing jobs that are created.

China delivers results because they have the will to, Americans just want status and vibes.

(Purpose of the system is what it does, watch what people do not what they say, etc)

With the switch to this paradigm at a certain detention center, the time to get an inmate mail simply addressed to them with an envelope effectively tripled, up from what was already like a week, and if you included any irregular shaped paper or cute stuff it’d get mangled in the process. Ask me how I know.

It’s certainly an exploitative service taking advantage of a captive audience. I do think the substances thing is making many more smaller jails consider it.

Ah yeah there are multiple definitions of 'acceleration' here. Unruh radiation occurs when you're not 'in an inertial reference frame,' loosely meaning that you feel acceleration. So in a rocket in space or (presumably) standing on Earth's surface.

What you say makes intuitive sense, but it was actually the opposite logic that lead Einstein to his general theory of relativity. Here's a slightly dorky but very good Veritasium video that explains this issue and general relativity https://youtu.be/XRr1kaXKBsU?si=1iudoAx5kWgWHHt-

Nobody is making you buy certificates to authenticate to an API. You'd get a certificate file the same way you'd get an API key, from whatever portal you're gaining access from. Nobody is trusting random PKI certificates to access APIs.

You also don't need any special certificates. The authentication certificates you hand out to API clients can be self-signed if that's what you want, but you probably want an internal CA of some kind to hand out/revoke certificates the same way you have some kind of API key storage.

You're right that the browser UI is pretty terrible. Especially on Firefox, I should add, which decides to maintain its own key store. On all other platforms you just open the certificate and hit next a few times and you should be good.

As for picking the identity to use, there are easy ways in the TLS protocol to signal what certificates qualify, and there's no way you're going to have multiple certificates signed by the same Acme Corp Ltd. with private key 0xffaabb... Websites that aren't set up correctly will prompt users for a certificate to use, but that's the other websites' fault, as well as the browser's to be honest.

Client certificates work fine. They work so well, that they've been reinvented and stuffed into JWT, but now in weird JSON. Various Kubernetes overlay systems use auto-provisioned client certificates to ensure confidentiality and authentication between pods (the cloud world calls it mTLS though).

Also a layman. But as long as your temperature is not absolute zero, particles inside you are moving, and if they have mass, they would indeed radiate gravitationally - until they slow down to a stop, that being absolute zero.

My understanding from pop science videos is that they can indeed evaporate, but only through decay mediated by the weak force.

What we need is fewer roads to maintain, but as you say a whole different problem.

It took a while to find numbers, but it seems like ~$80B in total gas taxes in a year is probably close. Meanwhile state and local governments (alone) spend over $200B on road maintenance and construction while the federal government spent about $60B on the interstates.

$80B is a lot, but if gas taxes covered even just car infrastructure it'd be an extra $1 a gallon already. Even without EVs. In case anyone was under the misapprehension that roads are budget neutral. Frustrating (to get more off track) that other transit is expected to somehow be profitable when roads are subsidized so heavily. I wish it wasn't so critical for our supply chain, EV trucks probably works a lot better between a train terminal and final destination than it does hauling across I-40.

> unguided “water-cooler” interaction

This meme needs to stop. Knowledge transfer from experts to novices is way too important to be left to chance. And thanks to pre-pivot StackOverflow we even have considerable data on how much better it can be done, at least for white collar industries. Reducing the effort of experts to give advice, and enlarging the audience benefiting from a singular effort to write it down is orders of magnitude better than chance.

>They are also quite good at translating poorly written and only semi coherent writing, which can be incredibly useful if the person you are communicating with is quite sloppy.

You see this with recent automated translation on YouTube. If the creator of (say) an English-language video doesn't upload subtitles, YouTube automatically creates them based on the audio, but they lack punctuation and have nonsense phrases. The AI-driven translation of those subtitles to other languages cleans up the text along the way, so the end result is that non-English speakers get better subtitles than English speakers.

> Sturgeon's Law applied then as it does now; 90% of everything is crud. Go back 20-30 years, and the shows you remember as great are only a tiny fraction of the total output. Some (like Monty Python or Brass Eye) were extreme outliers.

I want to back up and support this point: just pull up a list of shows on Wikipedia from any TV channel you can remember, ideally one with a long history and just go through the 60s, 70s, 80s, 90s, 00s, 10s etc. You're going to find a lot more cream the further forward you go into the future, and maybe, depending on the channel and your own personal tastes, a drop off in the last 10 to 15 years. Most TV was just bad, but old TV especially. For every "All in the Family" or "Cosby Show" or "The Wire" or "Frasier"; or to make this more British: "Sherlock", "Doctor Who", "Monty Python's Flying Circus", there's just dozens upon dozens of terrible shows. They each had their audiences, the ones that weren't cancelled (and even some of the ones that were), but it's like, nobody remembers the dirt underneath the flower, but they remember the flowers that they liked.

Terra lang is pretty cool but Pallene and Terra are significantly different. Terra is a language built for multi-stage programming - basically like lisp quotes where you're jumping between something like a compile time context and a runtime context. It's embedded in Lua, and uses Lua as the compile-time language IIRC. Pallene is strictly compile-time. It is a Lua-like language with type hints that can compile to Lua or to C code that is optimized for use in Lua's C API. So if you had some Lua module that was frequently calling to C for whatever reason, all those calls come with a performance tax. Pallene aims to lessen that particular penalty. They have a white paper where it compares several algorithms with stock PUC-Rio Lua, LuaJIT and pallene against each other and it's pretty interesting where each tends to shine over the others.

> The issues are actually more pernicious

Some people are just gullible and will always believe what they find to be socially qualified. Some people are just assholes who knowingly harm other people with false information for profit. People who live behind screens find this hard to accept, but people are generally predictable and follow predetermined paths according to their personalities.

In the mean time I will continue forward with common sense and guidance from licensed healthcare providers. I am not responsible for the bad decisions other people choose to inflict upon themselves or their children.

>I wish our copyright laws (I'm in the United States) were more considerate of the needs of computer historians and retrocomputing enthusiasts. 95 years is much too long of a copyright term for software that gets obsolete after 10-20 years.

Reposting my proposals regarding copyright:

Any content, once published/distributed/broadcast in the US, that is not made readily available to the public going forward loses copyright protection. This includes revisions.

* A film, TV show, sound recording, book, or any other copyrighted content must, once made available for public purchase, always remain available. If the only streaming service willing to pay to stream your movie has the smallest market share, too bad; the market has spoken on the value of your content. An ebook can fulfill this purpose for a print book; streaming can fulfill this purpose for a theatrical or physical-media film. But it must be available to maintain copyright.

* Compulsory licensing should apply; if Netflix wants to pay the same amount of money as the above-mentioned small market-share streaming service for the film, Netflix must be allowed to do so. The film's rights owner can demand more, raising the price for all, but if every outlet refuses, the film immediately goes into public domain. This process is reversible, but it would set a ceiling to prevent the owner from setting a ridiculously high price to prevent its availability.

* If a Blu-ray of a film or TV show has excised or modified scenes for whatever reason, and the original isn't also made available (whether on a different "theatrical cut" release, or as a different cut on the same disc), the entire original version immediately goes into public domain.

* If NBC posts Saturday Night Live skits on YouTube that have removed "problematic" scenes[1] without explaining the differences—a diff file, basically—the entire original skit loses copyright protection.

Separate issue, but also very worthwhile:

* Streaming services must make all data regarding their content available in some standardized format. Consumers should be able to use one application to access all content they have access to. The creator of SmartTube (a very nice YouTube-compatible player) should be able to add the appropriate API support to search for and play Netflix/Prime Video/Disney+/Paramount+ content.

The above applies to software, too. Legalize abandonware!

>While I'm on the topic, there used to be a museum in Seattle named The Living Computer Museum where visitors could actually use old computers. I went there in 2019 and had a wonderful time; it's sad that it didn't survive the COVID-19 pandemic.

The museum closed because of COVID-19, but the real reason it did not reopen is because Allen did not create a dedicated endowment, and his sister and only heir was uninterested in maintaining the museum.

I think you are bringing up an interesting discussion of curation vs. word of mouth. Where exactly do you draw the line?

Players counts kept increasing because a people came across the game on social media - upvoted reddit posts, high number of retweets, streamer sponsorships, etc. And a lot of that got rolling only because of initial positive reviews and PR. But isn't upvoting/downvoting something on reddit or other social media a form of curation? Is there even such a thing as pure word of mouth on the internet?

Need to read this asap, but 6.5% is an exceedingly small effect size and not robust given many confounding developmental and technical factors. The typical coefficient of error between volumes of even large brain regions in genetically identical mice is usually well over 5%. And I suspect the transgene was only tested on one genetic background—-usually C57BL/6J.

Will emend this post tomorrow with corrections after reading carefully. I can say with reasonsble assurance that no one has measured and weighed more mouse brains than I have ;-) (except you John Wong)

I wonder if history is going to repeat itself?

In the '70s the US changed emission standards to be quite a bit more strict, as part of the Clean Air Act of 1970. The problem of smog in major cities was getting out of hand.

Also in the '70s there were periods of gas shortages and high prices due to world events that messed up oil markets, such as the Arab Oil Embargo in 1973 and the Iranian Revolution in 1979. This led to demand for more efficient cars.

US automakers were slow to respond. The often just retrofitted existing engines with emission control equipment that significantly lowered performance and reliability.

Japanese automakers, who at that time had only a small share of the US market and were not really taken seriously by most consumers, were also dealing with new strict emission standards in Japan. But they responded by quickly designing new engines designed with low emissions and better mileage. And they exported those cars to the US.

By the time US automakers finally started making new design decent low emission cars with better gas mileage instead of badly retrofitting existing designs those Japanese makers had established with the public a reputation for making reliable, efficient, low emissions, and affordable cars.

Some people said the Japanese cars were only affordable because of cheap labor in Japan. (Japan in the '70s was like China is today when it comes to manufacturing). But then the Japanese car companies started manufacturing many models in the US, showing that affordable, high quality, reliable cars that met emission standards and were efficient could be made with US labor.

I wonder if we are going to see the same thing with EVs?

I've wondered this too. I have a little home server with some self hosted services, and I use a client cert on the reverse proxy to add an extra layer of security before the user can even reach the app. This works fine when accessing things via the browser, but if you want to use something like a mobile app, it almost certainly won't have support for it. It's up to every single app dev to implement support for passing in a client cert on the http requests.

I suppose a VPN is really the better answer here, but that's a pain if I want to give anyone else access and is less granular.

> the exact same place

I'm saying if other countries want to debt-collect in case of a default, there are other levers they can tweak besides just showing up at the US' door and saying 'give us our money back'. There are trade levers like tariffs, bonds, foreign currency reserves, gold reserves, and more. And I daresay in a concerted effort the US wouldn't be able to do much, unless it dares to risk enraging the entire world. In which case it would be able to do less still.

Funnily enough, it has already got halfway there, which was precisely my point. And sufficient damage was done to the markets that it managed to erase 4 years' worth of growth in one week flat, with a rather muted recovery afterwards.

It’s long past the point hybrids were a good solution for the majority of cars. They were a good idea to start phasing in 20 years ago, when the Republicans decided that they were proof you were a tree hugger ivory palace stuck up asshole for even considering them.

So we completely missed the entire thing. They were a never very big part of the market. And now people are saying we should transition to the thing that we should have been transitioning off of.

California didn’t mandate EV only tomorrow. No sane person has mandated EV only in the US that soon.

The chose 10 years from now.

People vastly underestimate how much progress we can make in a relatively short time without massive individual improvements. People always think the future is much further out than it actually is, but when we look back it seems like things happened in a snap. Because we always underestimate ourselves.

Every time infrastructure gets better, it enables more EVs. Every time battery technology gets better, it enables more EVs.

It’s doable. Other countries are showing it can be done. If we get 5 or 7 years from now and find out we need to extend the deadlines some they can do that.

Having the federal government come in and force a state to stick their head back in the sand until the political winds change doesn’t help anyone.

Remember: states rights if we’re out of power, federalism if we’re not.

Take a closer look at a picture of Kruskal coordinates, e.g.: https://upload.wikimedia.org/wikipedia/commons/1/1c/Kruskal_...

Those closer-and-closer line spacings are hiding a mathematical infinity, which isn't physical for finite-lifetime black holes.

Conversely, look at: https://en.wikipedia.org/wiki/Eddington%E2%80%93Finkelstein_...

The ordinary Schwarzschild metric diagram in that article makes it crystal clear that in-falling observers asymptotically approach the horizon, but never cross it.

Read the next section as well, which uses the "Tortoise coordinate"... which again uses the mathematical infinity to allow the horizon to be crossed.

I really don't understand why people keep arguing about this!

If you find yourself writing an infinity symbol, you've failed at physics. Stop, go back, rethink your mathematics.

Hey HN

We loaded a BigQuery dataset of all of Hacker News, every comment, story and user, into camelAI.

You can ask questions like:

• “When does dang tend to comment during the day?”

• “Which domains have gained the most submissions since 2015, year-over-year?”

• “How has average comment length changed each January since 2007?”

• “Top five users who link to arXiv papers the most.”

It's behind a log-in to prevent abuse but free to use for 10 messages. No payment info required. We use OpenAI o3 or Claude sonnet 3.7 for the agent which can be really expensive.

Would love feedback especially around graph/chart quality and o3 vs sonnet.
