This logic breaks apart in high positive externality areas, like public transport (or indeed postal systems).

Public transport brings a lot of value to other businesses and communities it operates in that can't be directly captured in fares. Which means that if a public transport system is profitable and the goal is maximising total economic (and social) value of the area as a whole, the system either under-invests, or is too expensive, or both.

The classic economic solution to this is subsidies: capture some of the generated value in taxes, re-invest back into the transport system. However, this makes the business part of the whole arrangement almost meaningless, because the amount of optimal subsidy can't be objectively determined. It's impossible to distinguish a bad business losing money from inefficiencies from a good business asking for subsidies to optimise its total impact.

There are some peculiar arrangements that some countries and systems were able to create, like direct land value capture through transport companies buying and selling property. But those cases are pretty exceptional and for practical purposes don't scale.

I'm referring to the fundamental idea in AI of knowledge representation. Lisp is ideal for chapters 1 through 4 of AIMA, and TensorFlow has shown that NN can be solved well with a domain specific language which lisp is known to be great for.

In fact, the first edition of AIMA even had a NN and Perceptron implementation in Common Lisp. (https://github.com/aimacode/aima-lisp/blob/master/learning/a...)

It is hard to even disprove that we aren't a Boltzmann brain that hallucinated entire reality. Assuming the simulation is perfect(or at lest consistent) the only way to falsify it is to get some impossible estimates for required CPU/memory/storage. I think the whole "if simulations are possible, multiple ones will be created" falls apart when 1 second of running simulation requires several years of compute.

In the long term, Venezuela has more proven reserves (but much less production capacity). Or nuclear + renewable will overtake fossil fuel. In either scenario, Saudi's share of total global energy production will likely decline by late 21st century.

And in non-oil GDP growth, UAE is currently outpacing Saudi.

As to "everyone there was still as rich as ever due to the oil money", depends on who "everyone" is: 77% of the total workforce in Saudi is migrant workers, many of whom earn < US$5000/yr. They're not citizens.

I learned to program in VAX Pascal, and didn't learn VAX C until later. I always found Pascal more intuitive, especially for string handling than C, and combined with the VAX/VMS System library and Runtime Libraries was able to build quite complex systems in Pascal. I found out later, after I joined DEC, that VAX Pascal was a popular Systems Programming language for a while.

As far as I can tell, enabling the trusted/untrusted security feature breaks a lot of basic features, including clipboards, XRandR, GPU acceleration, XKB keyboard layouts, and whatnot. It's theoretically available but practically useless.

Xnamespaces looks to be more promising, but as far as I can tell that's still a WIP with little documentation, and from the documentation I can find it looks like it still breaks things like clipboard functionality.

That was a TV presentor from a children's programme called Blue Peter.

If you think that looks dicey, search for the video of when another Blue Peter presenter,John Noakes, cleaned Nelsons Column in Trafalgar Square. Note the overhanging wooden ladder and the entire safety equipment was a pair of flared jeans and platform boots!

He also climbed the mast of HMS Ganges which is possibly even more heart stopping.

People are able to be themselves and relax when they feel safe. Safe from judgement, rejection, reprisal, etc. When you're with a group of people you don't know, you don't know how safe they are.

Getting drunk helps people feel uninhibited from all of that. There are a million other ways to feel safer with new people, but drinking happens to be extremely easy and quick.

This list is for little dinner parties held by women.

I could tell a woman write this at 11 "gender balance." No, just no. If you are a man thowring a party the one and only concern you have is throwing every bit of effort at making sure women will show up and not be outnumbered 2:1 or worse by guys. They will all leave and the reputation will forever ruin your chances of having women show up in the future. They talk.

If you are a man throwing a party you have to actively turn away other men. There is no other way. You have to rotate bouncing duty.

It's really not sane to do so, today.

You're literally applying birth sin for it to make sense, because none of the Spanish people alive today had anything to do with it

Even worse, what hnidiots3 was trying to convey: 99% of the population that were alive during the time period you'd have described as "Spaniards" were entirely uninvolved in these actions, and wouldn't have supported them either, likely.

While the Mayan culture was literally doing human sacrifices - the average person living in Spain wasn't inherently evil and wanting to cause suffering to other people. Despite their culture being kinda shit.

They just wanted to live their live, which was mostly being a farmer and working.

It's an open secret that UK universities are propped up by international students paying crazy fees(as much as £35k/year) to come and study here, and most of them are from China. Even when I did my CS Masters degree at a Russel group university I'd say half of the course was international students paying full fees, I was repeatedly told by professors that they are vital to funding of the Computer Science school and university as a whole(which is insane considering how much home students are paying, but I digress).

Anecdotally - some of them(definitely not all, not even a majority) - clearly didn't care about actually learning anything, they just spent the entire day in the lab playing LoL or didn't actually turn up. In a private conversation with our professor he said he's basically not allowed to fail them even if they don't turn anything in, the funding they get is far too important. And they still have to somehow produce an MSc thesis at the end to get their degree, so in the eyes of the university they are still passing correctly to get their degree.

Either way - UK universities are too dependent on that funding to risk angering China which can easily make it a pain to go to UK to study.

"Europe"? I can assure you, the party cultures in Spain, Scandinavia, France and Greece are all pairwise so dramatically different that the U.S. are not the counterpole, but just another flavor in the sea of possibilities. The same applies to different cultures within these countries. Across areas, ages, socioeconomic backgrounds, political leanings, hobby groups.

It's astonishing to me how many comments around here are lumping everything together under specific nationalities.

Could lead to significant efficiency gains for EV's, because 1/4 of the motor weight means better power-to-weight ratio... a lot of things will automatically get better.

YASA was founded in 2009, a spin out from Oxford University following the PhD of founder and still CTO, Dr Tim Woolmer.

"Over the decades that followed both of these technologies were explored. But despite the potential for weight reduction, smaller size, shorter axle length and increased torque, it was the difficulty in manufacturing the axial flux technology that limited its commercial viability, because the motor could not be made by stacking laminations, as with radial machines."

"The breakthrough innovation came by segmenting the axial flux motor in discrete "pole-pieces", so the motor could be manufactured using Soft Magnetic Composite material.

SMC can be pressed at low cost into a wide variety of 3D shapes. This removed the need for the complex laminations, overcoming the major manufacturing challenge of the axial flux machine."

"In 2025, after a £12m investment, YASA opened the UK's first axial-flux super factory, in Oxfordshire.

The opening of this facility boosts YASA’s manufacturing capacity, setting new benchmarks in e-motor technology and quality, and enabling production to scale beyond 25,000 units per year."

This is awesome. Lighter motors also make electric flight more viable

The centuries of ethics discussions have nothing to do with the current institutions that gatekeep science and health with worries and trivia, any more than philosophers of nature are responsible for enviromentalists not letting us build housing. I'm entirely referring to anti-growth bureaucrats. https://slatestarcodex.com/2017/08/31/highlights-from-the-co...

Ethicists seem worse for the world than actually unethical people because they bind the majority of good people from progressing, which is what gets us out ahead of our baser natures.

The one trick pony of LLMs is a nice trick, but the quantity of data centers just does not add up. The costs are excessive, and I just can't see the justification to pay for services for all of this. What ever goes in these centers shrinks due to improvements, and it also depreciates quickly. And, for most of the LLM stuff, there is no error bars, so the results are always suspect.

> Similar to eating a Danish pastry, like the Danish only made one type of pastry...

Amusingly, the danish pastry would be called "wienerbrød" meaning: bread from Vienna. like the Viennese only made one type of pastry...

Luckily, the Viennese don't call it something-from-somewhere, so the chain ends at 3. I wonder if there is a 4-chain of terms anywhere.

This should be upvoted. A lot. The downvotes are ill-informed.

https://www.earthobservatory.nasa.gov/images/77060/mayan-def...

From newish imaging. We can see the impressions of vast jungle swaths cut down and way made for planting food and houses. This looks to have disrupted the water cycle enough to cause cinotes (underground water systems and only source of drinking water) to deplete. We see sacrificial remnants below the modern water line. Their water disappeared and so did their civilization. By the time the Spanish arrived, the local people had no knowledge of how to build nor maintain their now ancient cities, the jungles regrew, water came back, and sacrificial artifacts were covered by replenished water levels.

They are an example of man made effects on local weather leading to the downfall of an advanced civilization.

And how is any of that related to alcohol? My friend can open up to me when we are in a safe environment without the need for first ingesting a drug. It's not the alcohol that causes the safety.

Maybe it's a ritual, that could explain things partially. But maybe a ritual worth abandoning. Just like we did with smoking, and everybody gained (well except the tobacco industry).

I'm sure the boozemakers won't let go without a fight though. But so far they have plenty of help.

Because then I have two seperate boards to power, house and protect. Combining those into one would make for a smaller design footprint, in our case. With this particular product, portability and compactness is ideal, since it is intended to be used on job sites to mark steel banding or tags. Often times, these guys are working out of a very dirty trailer that's already crammed with equipment, so space is at a premium for them. The machine does nothing special, so size tends to be where the competative edge is in that admittedly niche market.

There are not that many agent frameworks around at the moment. If you want to be provider independent you most likely either use pydantic AI or the vercel AI SDK would be my guess. Neither one have built-in solution for durable execution so you end up driving the loop yourself. So it's not that I don't use these SDKs, it's just that I need to drive the loop myself.

I'm guessing that his 1st person description of the human sacrifices carried out by the Mayan and establishing a connection between those and the need to erase the culture that enabled them and that he - wrongly or not, we can't know anymore - saw as enabled by those books had some weight there...

The Spanish crown didn't have in mind to destroy other people books, but then again, they also didn't have in mind that they casually, recurrently and nonchalantly offered human sacrifices to their "gods".

Probably the order of priorities for the Spanish crown was books < human sacrifices.

Strange times, those, eh?

I recall malls in the Gauteng area sometimes having netting or shade cloth over car parking bays. As a way to prevent hail damage to cars that can occur occasionally but unpredictably. Leaving your car out under the sky for hours was a risk.

I wonder how well the solar panels will stand up to hail.

Some parts of the interior of the USA will have very similar hail considerations.

If you remember the last time Trump lost an election there was a violent coup. I do not hold out any hope that there will be an orderly transfer of power.

Also, I wasn't comparing the US to anyone, I don't care what China is doing. I was just listing the direction that the US democracy is heading in under Trump. And that direction is a systemic extension of presidential powers that go largely unchecked. The Wednesday ruling of the Supreme Court will be a watershed moment in this case, if they will not check his overreach on tariffs, I doubt that they will check anything that Trump is doing.

With Three UK I used gathered evidence over the course of 4 months to wiggle myself out of a £46/month 28-month 5G contract (had to pay £200 remaining on my iPhone 16 Pro) when I demonstrated that my phone was basically useless whenever in the postcode are where I live, even if I always had 1 bar 5G signal.

Not even phone calls would go through, let alone calls on Whatsapp et al, or loading websites using something heavier than just text.

Have raised a _formal_ complaint (they must report it to Ofcom), and after that it was just a matter of ensuring I lost enough phone calls to demonstrate how many ended up in my answering machine.

The fact that Wifi calling is also super buggy and almost never work, played also a big role.

My problem is, all other mobile providers in my area are even worse, showing LTE or 4G. So I just need to wait for them to strengthen signal, or move!

I’ve had similar experiences.

In my case it wasn’t like dreaming exactly, more like that in between state where you’re falling into a nap but still awake. Sound was kinda like being underwater, in fact recovering consciousness very much felt like surfacing into reality for lack of a better term.

It was kinda cozy, definitely not an experience to be scared of.

That's probably it. It's a ritual. A costly one though, in terms of money as well as health. Direct cost (liver, brain cells, ...), as well as indirect (accidents, fights, ...).

> That's what I like about them young Gen Z, they drink less alcohol.

I wouldn't celebrate to soon. Every movement eventually spawns a countermovement. Next gen might be the most booze consuming ever.

The more I think about it, the harder it is to recommend anything else for the average Windows gamer/prosumer but first-time Linux user.

- Rolling release, so you don't have to do a major upgrade twice a year - which would otherwise be much more often than Windows.

- Latest kernel and graphics drivers, so it works with newly released hardware with the best performance.

- Steam, NVIDIA drivers, H.264/H.265 codecs, Gamescope, GameMode, MangoHud, etc. all in the default repos - a huge boon for new Linux users compared to having them in an external repo like RPM Fusion or having to install them manually, which can otherwise cause confusing dependency problems over the life of the installation.

- Nothing unusual about it that would be confusing or cause compatibility problems. It's just a normal mutable binary distro with a normal package manager, upstream packages, glibc and systemd.

The biggest issue is the lack of an official graphical installer, but while the install process is intimidating, it's not very difficult for people who are patient, can follow detailed instructions, and have a vague idea of what a partition and a bootloader is.

I wonder if the limitation of the application processor and Linux starting is mostly a default for the standard OS or an actual limitation. Typically with a hybrid SoC like this part of the point is that you can use the micro-controller as the power efficient thing that decides when the bigger application processor should boot or not. I'd be curious to see if that's possible with this one.

Shipping only Debian to start is fine by me. It has to start somewhere. And they seem quite responsive to making it work with other things. James Harton is plugging away at getting it working with Nerves (https://nerves-project.org) and he has it running with Buildroot already. Current repo: https://github.com/jimsynz/buildroot

Most recently they pushed their special sauce for the bootloader and how to produce the relevant mystery binaries. https://forum.arduino.cc/t/buildroot-support-for-uno-q/14108...

I share the sentiment that I don't trust that there won't be issues with Qualcomm over time. That company does have some pretty relevant chips though so I'm hopeful this means that we see them become more accessible on SBCs and embedded boards. I feel like they've been popping up more and more.

If they value this investment in Arduino they should now have a small wing of the company that pushes for things to be more open and even if they only consider that a marketing vector, if things are opened up for that purpose, quite possibly a win. But Arduino might also be absorbed into the amorphous megablob and this is the last we see. I hope not.

I don't think this board is that weird. It is just coming from the Arduino side and moving into Raspberry Pi territory. Personally I want to run Nerves on the application processor and get some practice with Zephyr on the MCU. Seems to already be supported: https://docs.zephyrproject.org/latest/boards/arduino/uno_q/d...

Also why no mention of the LED matrix. This is something RPi devices fail at. Providing som default way of neat output. First time plugging this in it starts doing fun stuff.

Butter emulsifies into a sauce just from the residual heat of the spaghetti (and some mechanical action - stirring, pan flip, etc)

Oil needs a bit more help, otherwise it's just grease on noodles. The starchy water the pasta was cooked in can do most of the heavy lifting there, but the addition of garlic helps too.

The buried lede here is that Qualcomm is selling chips to hobbyists now?

https://www.digikey.com/en/products/detail/qualcomm/QRB-2210...

$20 for something that can compete with a Pi 4 is intriguing, more so if it has a real low-power sleep state like the Pis don't. It's a gnarly chip though: 0.4mm pitch and like two dozen power rails, plus the fanout looks tight even on an eight layer board. I don't see the PMIC they're using anywhere online either... fingers crossed anyway.

> nobody will RSVP because they're all waiting on each other to RSVP

The article discusses this. “Start by inviting your closest friends, get some yesses, then expand from there.”

The trick is that you already discussed the party with a core group. They are basically co-hosting the party with you. You already cleared the idea with them, heck throwing the party might even be their idea. So they won’t be waiting for others to RSVP. And then their yes-es provide the social proof to others that it will be a cool party and they too join saying yes. Thus the party grows like a snowball.

> a dedicated app for inviting people to the party is too much fanfare for my taste

It is not for you. It is for the party organiser so they don’t have to copy paste the same information to everyone (date, location, short description). It also sends reminders to people who want to be reminded.

> A good party fosters serendipity.

Yes. I agree. Serendipity at what happens at the party, who do you meet, what do you folks do or chat about. Not quite sure how a party invite ruins any of that.

In the UK it's fairly common to use the term "Swiss cheese". Most people would know you are talking about Emmental or Gruyere and it would have the bubbles/holes in it.

Although they are not the same cheese, they are quite close in texture and flavour and are fairly interchangeable to the point where I don't think a significant number of people could tell you which was which.

There is also the Swiss Cheese Model which is when several unfortunate events all line up to cause a major incident.

Yeah it's nonsense, because the author has described the standard "read, process, write" flow of computation and decided that if you remove one of these three, then everything is safe.

The correct solution is to have the system prompt be mechanically decoupled from untrustworthy data, the same it was done with CSP (content security policy) against XSS and named parameters for SQL.

There is no disagreement about that. But the simulation hypothesis claims that is is more likely that what we perceive as reality is a simulation, run by someone else, than that we are in "real" world.

I think it is worse hypothesis than even Drake's equation - there, at least we know all factors, we just have no idea what their value is and with sample size of 1, the current uncertainly is like 40+ orders of magnitude. That still brings us closer to "is there inteligent life in universe" answer than we ever got with "is this universe a simulation".
