I ponder this kind of things from time to time. This one makes a very enjoyable puzzle because it is extremely simply to move people on a conveyor or a rolling platform but amazingly complicated to get them on and off if you want to run it at any meaninfull speed, absurdly complicated.

My mental gymnastics is mostly trying to mobilize an entire city with the concept. I see some research suggesting there is lots of room between walking and driving distance. Bringing a bicycle also has its down sides.

Because getting on and off is already so difficult one tends not to notice the other problems with the tech. A simple crossroad is already a problem.

Moving fast is no issue for the more athletic passenger without luggage. It is also the most useless device to them. People with mobility issues don't have to get on but they do have to cross the road.

You would want to slow down or stop the surface, put a fence around it, you would want chairs, a roof would be nice, perhaps walls so that you can further control the climate. And then you have a bus, metro or tram. (haha)

One cool variation (not my idea) was to have a moving platform fromwhich to get in and out of a moving train, tram or metro. You could also make vehicles that connect on the sides. Those would have lots of fragile moving parts and potential dangerous situations if they fail. I see a night train misaligned with the station one time with the last door opening above the entrance of a pedestrian tunnel. A drunk guy almost walked out into the 5 meter drop. That seems preferable over falling between two moving trains.

>Does knowing that an organization that's building out a social graph for as much of the developed world as they can has ties to Palantir, which has ties to governments, leave you with a warm fuzzy "I wanna give them my data!" feeling, or something else?

I think he point is that most people won't ever even know that this is happening.

>why would Partiful need to ask you for that information?

well that site had a lot of annoying stuff when entering my name. Probably from my mom. But I'm happy to report that it did not actually have my phone number on record.

But that's not even a dig on my mom's internet habits. She's a government worker so a lot of that is probably public record. They were just able to piece together a lot of my info based on that.

This is my first SaaS project — it automatically scrolls through a given website and narrates what it’s about, then compiles the whole thing into a video.

I built it because I wanted a simple way to show a website instead of just sharing screenshots or static previews.

Under the hood, it captures live page sections while generating a real-time voice-over using AI. The result is a narrated walkthrough of the site — perfect for sharing demos, portfolios, or landing pages.

I’d love to hear what you think — especially around improving narration, pacing, or potential use cases.

My comments (this thread) were in context of 120 years ago when cars were a rich person's toy and most people lived on farms and so didn't have access to the transit that existed. That a store can make it today is different because context is different.

How many of the customers of the Warhammer store walked there from their house? How many came from a different cities because it was the closest store? The store does well because it can draw from a much larger area than a pure walking (or the limited trams of back then)

Similar for guitars - I expect a city of 100k to support 1-2 guitar stores - but I expect the majority of customers are not walking. Maybe they drive, maybe they take transit.

That's not $20 to compete with a Pi 4, that's $20 for the bare chip. You have to buy all the supporting hardware on top of that. Hobbyists want to avoid routing LPDDR like the plague. There's also the inconvenient fact that digikey shows "0 In Stock", so this listing is just that, something you can't get your hands on as a hobbyist.

It’s only like debt for the purposes of government budgeting. For a person, the ‘student loans’ are much more like a graduate tax which is weirdly regressive. The tax is only on monthly earnings above a certain level so lower earners pay a much lower effective rate than the marginal 9% rate. In particular, if you aren’t earning money you don’t pay, when you die your estate doesn’t pay anything, and if you go bankrupt the ‘debt’ is not written off.

£50k is a lot to your sister because of the sorry state of the British jobs market.

>Initially, the database contained only the DNA of sexual offenders. But, over the next five years, it grew to include people convicted — or merely suspected — of a much wider range of crimes, including murder, terrorism, drug trafficking, assault, theft and property damage.

>The process of being removed from the DNA database is so onerous that few pursue it, Mr. Poitevin said. Those who refuse to give a DNA sample face at least a year in prison and a fine of at least 15,000 euros, almost $17,400.

Totally agree. But the docs aren't going to guide their model. Contradiction between the reality of a service, monitoring, and docs don't go to "align with the docs" they go to "align docs to reality"

I don't like this. I too have looked like an attack on their models using things inside the customer-side of google, took special relationships to get over this, an ongoing threat to how we relate to them.

(it's not in GCP btw. different arc of the megaplex)

There's a reason Google has a reputation of "Don't use it for anything that you can't afford to have disappear with no notice or recourse."

You also can't expect it to get any better, both because Alphabet has never shown any interest in improving things and because you and the services you've been using them for aren't the new AI hotness. Even if you're absurdly profitable for them (and you're clearly not) you're not in an area that their internal people are competing to serve.

One thing I've observed in my career is that if you take the extra time / are good enough / have the experience to ship something solid enough that nobody ever thinks about it, you never get nearly as much credit as the folks who quickly ship broken things or the folks that parachute in to fix those things.

I've changed my behavior to reflect the incentives but remain sad about it.

I don't see the weight reduction being very significant.

If we take a Tesla model 3, I believe it weighs 1611kg, and the motor shows up at 80kg if you google it (no idea if this is correct). This YASA motor by comparison weighs 14kg. So, this would drop the vehicle weight by 66kg out of 1611, so that's a 4% saving.

This has always seemed intuitively obvious to me. I use a lot of em dashes... because I read a lot. Including a lot of older, academic, or more formally written books. And the amount used in AI prose has never struck me as odd for the same reason. (Ditto for semi colons).

The truth is ... most people don't read much. So it's not too surprising they think it looks weird if all they read is posts on the internet, where the average writer has never even learned how to make one on the keyboard.

Delve on the other hand, that shit looks weird. That is waaay over-represented.

>it's important to understand that some friends are better one-on-one as opposed to group gatherings

sounds like a great origin story for someone who finds out they aren't invited to any parties and then self-exiles themself from the group. Or society as a whole.

The article says as much:

>when nothing smacking of social selectiveness can be discussed in public, people inevitably begin to organize activities in secret. These conspiracies often lead to more problems down the line, and the end result is as juvenile as anything a seventh-grader ever dreamed of.

I wish people could just be direct and tell Cat Piss Man to take a good shower and clean their literbox more often instead of playing these mindgames. If they don't correct their behavior, then sure. You need to cut them off. But in my experience around neurodivergence, it's much easier to be upfront about these things than avoiding it.

Unstable things tend to wobble around until they find a stable configuration, and then remain there (by definition). This goes for pretty much everything.

Introducing some external perturbation can destabilize the thing until it eventually settles into a new stable configuration. But if you've built up lots of systems around the old stable configuration this kind of sucks.

(Also, stable configurations can be hard to reach, and "eventually" might be a rather long time.)

> Under this new $38 billion agreement, which will have continued growth over the next seven years, OpenAI is accessing AWS compute comprising hundreds of thousands of state-of-the-art NVIDIA GPUs

Does then mean that the Oracle/OpenAI data center they're currently building (was it "Stargate" maybe?) won't be ready for at least 7 years? Or does it make sense for them to have both their own data center + use AWS for hosting?

Godel's proof relies on the self-referential nature of the Godel sentence; without that, his theorem does not apply. Generally you need arithmetic, but also (something equivalently expressive to) universal quantification. Physical theories do not need to include that.

Note Godel's proof is mechanically exactly analogous to Turing's proof of the undecidability of the halting problem, because ultimately it's the same thing (Curry-Howard, Prolog, and all that). So you can bypass arithmetic, but you can't really bypass self-reference; just like programming languages need some looping or recursion (or equivalent expressiveness) to be Turing-complete, mathematical theories need universal quantification to be subject to Godel's Incompleteness Theorem.

Of course, you can have a physical theory that _is_ Turing-complete, say the Newtonian billiard ball model (and, y'know, we can build computers); but that doesn't mean the theory will necessarily tell you, as a static, measureable physical fact, whether a particular physical process (say, an n-body system) will ever halt or loop, or go on forever with ever-increasing complexity; so you could (in principle, in Newtonian mechanics) build some (mechanical!) physical system that simulates the Goldbach conjecture, or looks for solutions to an arbitrary Diophantine equation, but if there are no integer solutions you'll never actually be able to show it; the theory is incomplete in the mathematical sense, but just as complete a description of reality's rules.

> literally has a thick salt crust inside of the holes.

It is hard to take you seriously when you spread misinformation.

The Calcium lactate crystals are technically a salt, but not what we would commonly refer to as salt (sodium chloride).

Yes, your language might transliterate to salt or salt crystals in English but it is misleading to call them salt in English.

To me this is very obvious when you eat the crystals (they don't taste salty, and they have only a very soft crunch).

>> MATE lacking volume and WiFi controls

> One of the good strength of OpenBSD is that the cli utilities are quite nice that I've not installed gui replacements (I'm using cwm). I don't mind doing a few `doas ifconfig` every once in a while.

I also don't mind doing things like this for network, but for volume this is very much an instant always-there requirement. If I need to mute/lower/raise the volumne in a hurry, I don't want to hunt for the application playing the sound, then find the volume slider on it, etc.

This is literally a deal-breaker for desktop/laptop users.

What I'd like to know, if there are any OpenBSD people reading, is how hard is it to contribute a fix or similar to make the desktop environment's volume control work?

I can obviously fix it for myself with some gui script/keyboard shortcut/etc, but I'd rather have anything be in the default installation whenever I refresh the install.

What I can't do is start making supper for my family. I can't play games with my family. I can't practice my drums. I can't make chips on my lathe. There is a very long list of things people want to do in life that cannot be done. If what you happen to want to do at the moment is something you can do on transit good for you - but for many they are doing that as a second best because they can't do whatever it is they want to do.

Time matters in the above. If your trip is 15-20 minutes time to unwind seems to be universal and so almost nobody really has anything they want to do. If you trip if an hour that is cutting into other things in life. (Note that I didn't mention how you take the trip in this part, people who drive fast the same time concerns for longer trips)

I love this one: https://github.com/LearningCircuit/local-deep-research

I tied it together with qwen3 30b thinking. Very easy to get it up and running, but lots of the numbers are shockingly low. You need to boost iterations and context. Especially easy if you already run searxng locally.

I havent finished tuning the actual settings, but for the detailed report it'll take ~20 minutes and so far has given pretty good results. Similar to openai's deep research. Mine often has ~100 sources.

But something I have noticed. It didnt seem to me the model was important. The magic was moreso in the project. Getting deep with higher iterations and more results.

Yeah, but just like all other bolt-on databases, now your vital data/biz logic is disconnected from the hot new VC database of the month's logic and you have to write balls of mud to connect it all. That's a very big tradeoff (logic, operations, etc).

Furthermore, when all the hipster vector database die or go into maintenance mode or get the license rug-pull when the investors come looking for revenue, postgres will still be chugging along and getting better and better.

Anyways, all this vector stuff is going to fade away as context windows get larger (already started over the past 8 months or so).

Much of the low skill labor were things like writing transcripts and turning receipts into plaintext. It was at a point where OCR wasn't reliable. There were a few specialist tasks.

The gig economy was very much a net positive here. Some people used it to quit factory work and make twice the income; some used it as negotiation terms against the more tyrannical factories. Factories were sometimes a closed ecosystem here - factory workers would live in hostels, eat the free factory food or the cheap street food that cropped up near the area. They'd meet and marry other factory workers, have kids, who'd also work there. They were a modern little serfdom. Same goes for plantations.

Things like gig work and mturk were an exit from that. Not always leaving an unhappy or dangerous life, but making their own life.

If it paid badly, just don't work there. These things push wages down for this kind of work, but this work probably shouldn't be done in service economies anyway.

What situation exactly? Tried the demo (https://joelseverin.github.io/linux-wasm/), seems to run fine. There isn't any benchmarking programs/scripts available inside of it, so can't really give out any numbers, but it doesn't seem to work worse than any other "Linux-in-a-browser-tab" I've tried earlier. Using a 5950x with Firefox on Linux 6.17.6-2 FWIW.

We do at Discourse, in thousands of databases, and it's leveraged in most of the billions of page views we serve.

> Pre- vs. Post-Filtering (or: why you need to become a query planner expert)

This was fixed in version 0.8.0 via Iterative Scans (https://github.com/pgvector/pgvector?tab=readme-ov-file#iter...)

If you are running a single service that may be an easier sell, but it's not a silver bullet.

>If you use one of the tools like Claude Code / OpenAI Codes, these could be trained on copyrighted Code.

COULD.

Copyrights arent protecting every individual function. It's identical clones only.

But if you havent literally cloned someone else's work. You have no fear of lawsuit here.

The one thing that could happen isnt AI making the same code. It's patents. Some sort of function of an app is protected by a patent. You as an open source option are likely rolling over and losing.You arent fighting some patent lawsuit and trying to invalidate their patent.

You take down the project and put in your calendar the day you dont infringe. You keep working on the project to make it super awesome. Then the day it comes, you have a big release as patent expiration day and have a huge marketing campaign to wreck them.

Fake documents are a problem for immigration enforcement officials. They are a problem that makes immigration enforcement harder, and requires officials to be more creative. They are not a problem for me, a legitimate US citizen, such that they require my rights or freedom to be curtailed in any way. And let’s be clear: that’s precisely what TFA is talking about: an unreliable, unauthenticated database that officials will believe over my legitimate and truthful statements of citizenship, and over my legitimate and truthful presentation of US citizenship evidence.

As I said in a different comment, we US folks have decided as a society that we don’t want to have mandatory difficult-to-forge national ID. When asked this question democratically, US voters and their representatives have repeatedly* turned down this option and explicitly banned the Federal government from issuing Federal ID cards outside of optional passports for international travel. We made this decision precisely because we distrust the sort of Federal government that would require us to carry that sort of document. There is nothing accidental about this, and you can find explicit statements of this bipartisan consensus all over real Federal legislation; there’s really no possibility that we did this by accident or without due consideration of the tradeoffs.

You’re correct that this lack of standardized documentation makes the immigration enforcer’s job harder, since they can’t just force people to produce proof-of-citizenship on demand and they can’t detain US citizens, and they can’t necessarily trust every paper document they’re given. I’m sympathetic! But that’s the tradeoff we’ve made as a society. The answer is not “throw out the rule book and risk depriving citizens of their rights because our job is hard.” The answer is: respect the rules you were given and due the best job you can without depriving US citizens of their rights.

And PS this situation is hardly unique: we also make ordinary cops’ jobs harder by requiring them to respect suspects’ civil rights and demanding probable cause to make an arrest. It’s tough! The result there is that cops have to work harder and be smarter; they don’t just get to detain anyone they want just because they might vaguely hypothetically be a criminal.

Executable "toy models" are excellent in practice for property based regression tests. The invariant is that for all inputs the behavior of the oracle ("toy model") is the same as the behavior of the system under test. AWS call this approach "lightweight formal methods[1]" and it's a good one. The problem is afaict there's no way to insert a TLA+ oracle into e.g. a rust proptest suite.

You can buy the chip, but I'm not sure what that gets you. The only publicly available documentation seems to be the datasheet, which only covers its physical and electrical specifications. I don't see any register-level documentation or even a BSP available for it. I don't think you'd be able to actually do anything with the chip without entering some sort of contractual relationship with Qualcomm.

All of this person's problems seem to stem from a practice of implementing business style setups at home. The truth is you don't need any containerization/VMs for a home server setup. You don't need all the nines for uptime either, it's perfectly okay to be offline for a week or whatever. It's your stuff! No one else has a say. The idea that everything has to be running on a separate OS from the one you use is a killer.

You don't need to start over in a new OS for this. Just don't cargo cult. Linux can do all this fine natively without containers and without risk in very straightforward ways if you ignore all the "deployal" memes or ideas of fallbacks. Just install nginx from your repos on your desktop, throw in some .html files to a directory and play.

How does this work with other countries not enacting 32-hour workweeks?

This will be a repeat of manufacturing going outside of US due to reduced standards (labor and pollution) and therefore cheaper manufacturing in China. And due to that blue collar work got destroyed in the long term.

Logically, unless there are high trade barriers for software/services/goods from countries that don't have similar standards, long-term, these jobs will just shift there.

I'd personally be more supportive of the 4-day 40-hour work week because I converted to that about six months ago, myself, and I'm not looking back. I find it works very well, for me.

I'd be all about 32-hour work week, but provided either employers were required to pay us all more, or the price of _literally everything_ in the US consumer economy came down. Cutting my paycheck by 25% would be devastating to the arguably modest lifestyle I have built for myself, so I can't see that ever being offset by just being generally happier because I'm not wasting the single life I have making someone else rich.

It was also used in the Koenigsegg Regera, the Ferrari SF90 Stradale and S96GTB, Lamborghini Revuelto hybrid and the Lola-Drayson.[9] The company is investigating the potential for placing motors inside wheels, given that AFM's low mass does not excessively increase a vehicle's unsprung mass.[10] "
