Imagine I own farmland worth $10M.

I claim we've had a lean few years, as we had to replace some aged equipment. I'm working all the hours god sends and only making $30,000 a year. There's also, uh, inflation. Market volatility. Climate change. Rising fuel prices. And I'm really worried labour costs are about to rise under this new government.

I also claim we can't sell any of the land without undermining the commercial viability of the farm; and the land would be difficult to sell profitably, because anyone except me and my immediate neighbours would have to travel a long way to farm it. And the remainder of our capital is tied up in crops, which obviously we can't sell until harvest.

On the other hand, it's an almighty coincidence that I needed to replace my tractor, my combine harvester, my skid steer, and my truck all at the same time, just as my kid turned 17. And that I just planted all those apple trees, hops and asparagus that I won't be able to harvest for a few years.

And yet - should MIT be in the business of second-guessing how farmers run their farms? Should my kid be denied a scholarship because some desk jockey in Cambridge thinks he knows the asparagus market better than I do?
you need space to do that, not many cities in Europe have the luxury of being built from scratch and having so much space to dedicate to a single intersection.

Where i live (in Rome) the streets are like this

https://as1.ftcdn.net/v2/jpg/04/93/42/24/1000_F_493422444_Hw...

edit: anyway the simplest solution is to turn every intersection into a roundabout, no traffic lights needed, clear right of way, cars can't go fast and in the end it also makes it easier for pedestrians to cross the street.
Correct. That is enough 95% of the time. (I made that number up, but it's not far from the truth.)
The problem is- that infrastructure is a scam. As in - its easy to build it, as its priced into the creation of a new house / suburbia. But maintenance is a piled up costfactor, not city and citizen has plans for. So everyone is constantly on the run from hoods were the infrastructure is decaying due to maintenance debt returns the road back to rubble.

So what they are doing is not different from previous "VPS" systems, its how they are doing it.

What is a "VPS" At its heart, Visual Positioning Systems are actually pretty simple. You build a 3d point cloud of a place, with each point being a repeatable unique feature that can be extracted from an image (see https://blog.ekbana.com/extracting-invariant-features-from-i...) Basically a "finger print"/landmark of a thing in real life that can be extracted from an image reliably.

To make that work, you need to generate a large map of these points: https://www.researchgate.net/figure/Sparse-point-cloud-Figur... Which basically involves taking lots of pictures with GPS tags on where they are. Google has the advantage of street view, Niantic has it's game. Others had to pay a bunch of people to go round a city with cameras.

Once you build that pointcloud (which isn't actually that easy, you can't do it all at once, and aligning point clouds is hard.) you can then use trigonometry to work out where a picture is. This is called "re-localization" which is a stupid name. The hard part is the data management. There are billions of points in the world, partitioning the database so that you can quickly locate a picture is the hard part.

Hence this approach, which is basically "train a model to do it for us" You still get a "VPS", you still need all that data, but they hope that a model will able to optimize for speed.

is it private?

No, the original system isn't private. If they've done their job properly, then nothing identifiable will be in the "map" as thats extra data you dont need. What they do with the raw photos, and the metadata that they contain is another matter.

I would say that you could generalize this even further outside of education. A few early successes in life can greatly accelerate one's trajectory, while early failures could set one many years back. And this happens independently of whether those events are due to skill or luck.

Amazingly, I believe that today, with the myriad of tools available, anyone can advance in sciences like mathematics at their own pace by combining black-box and white-box approaches. Computers, in this context, could serve as your personal “Batcomputer” [1]. That said, I would always recommend engaging in social sciences with others, not working alone.

Who knows? You might also contribute meaningfully to these fields as you embrace your own unique path.

"Serfdom is very different from slavery."

And Mac is very different from a PC, but they are still personal computers that pack some computing power...

My wider point was about unfree labor in pre-industrial conditions. There were many serf uprisings in Central Europe, which indicates that being a serf was sometimes very hard to bear.

We are so used to free labor nowadays that we can't really imagine a world where the vast majority of the population is physically subjugated to some lords.
In general I try to avoid nationalism - a lot of what one perceives as "my country ABC is the best at XYZ!" is just "I was born in ABC so I am used to XYZ!".

But...for the small niche of cycling infrastructure, the top 10 list is The Netherlands in places 1 to 10, then no country in places 11 to 50, and then Denmark in place 51.

What is important to consider is that cycling infrastructure is all around great in The Netherlands everywhere. Not just in the center of Amsterdam. Industrial estates, villages in the middle of nowhere, roads through forests, popular attractions or theme parks, islands: everything is reachable by bike, usually with bike lanes that are well maintained and physically separated from the main road, and often with bicycles having right of way on roundabouts etc.

The "clearing a path" idea is inane, but we do know how to absorb hypervelocity debris impacts while generating a net negative amount of debris.
At least where I live, such a type of intersection is used when a residential street branches off a large main road. You do not have a high volume of traffic going into this residential street, and "waiting for a crossing cyclist" does only take 1-2 seconds. So a buffer size of 1 is usually enough.

I am exactly in that line of work and that's not my experience. All our written communication is kept basically forever in case of investigation, and yet people don't second guess everything they write.

The only way to lose weight without damaging oneself is to combine more exercise with less eating, which means becoming comfortable being hungry. Yes, it's difficult -- especially after developing bad eating habits over a long time -- but moderation is required in all things. It takes a long time to become overweight, so the ramp down to a leaner existence must necessarily take a significant amount of time, or there's going to be added risk.

Just like in programming, there is no silver bullet; there's only hard work.
That may be, but Firefox certainly doesn't, and it's not that far from Chrome in terms of feature set, particularly in terms of supported web standards, or security. So I don't feel that a smaller Chrome team would be a catastrophe for Chrome.

Build more bike lanes.

To an extent, it's a self-solving problem. If you have great non-car transport options and an increase in traffic makes car driving less appealing, then more people will use those non-car transport options rather than joining the queue.
Yes, there is a significant cost to being built differently regardless of perceived advantages (by one's self or others). For example, as an autistic, I have to cope with finding interaction with non-autistics quite difficult for me, even if detail-oriented thinking can make certain tasks seem easier to me.
A significant number of my "native apps" on mobile are just webview wrappers. Some are really fancy and slick, but still. I think the mobile OS handling web apps in a more integrated way would help here more than making browsers more complex.
If I understand this correctly, it looks like the promise I saw in that 'Record Macro' button in my Excel toolbar in the 1990s might finally be coming to fruition in a wider and more capable sense! A pleasant surprise effect of the new AI situation if true.

I noticed in another comment that you said some steps can be made 'optional' (e.g. clicking through a modal). In my ancient Excel macro adventure, what I learned was that I had to tweak the heck out of the VBA code that Record button generated, which led to me just straight writing VBA for everything and eventually abandoning the Record feature entirely. I had a similar experience later on with AutoHotKey. What are the analogous aspects of Autotab to this? Also, to what extent is hand-manipulating the underlying automation possible and/or necessary to get optimal results?

For PHP 8.3, we upgraded production during the RC phase, but were prepared to revert back to an older one by not relying on the new functionality. Docker makes this easy.

As long as you do not use the new functionality, I'd claim that a new PHP version is no less stable than an older one. And on a contrary you would be missing out on some bugfixes that were deemed too risky to apply to an existing version.

Disclosure: I've got a commit-bit for PHP, so we had in-house expertise to diagnose issues ourselves.
Bikes are small and fast, and only a small fraction of cars will need to turn here as this is a street going in to a neighborhood. The chances of multiple cars wanting to take this turn and there being a long stream of bikes that holds them up is small. So 'never' is not the right word here, but the times this happens is negligible.
The backpressure is a feature and ensures people like me take a bike and train to work instead of driving
It's great that the systems are getting better. Maybe they should infict them on the public when they've reached a level where they're fit for purpose?

I wish urban designers in Poland learned from this. Our bike lanes are terribly designed, cars turn right into them with very poor visibility. The "solution" is that lawmakers introduce additional restrictions for bikers, which are unclear to everyone, so right now nobody really knows if bikes have priority on bike lane crossings or not.
it was the 80s, I used to walk to school at 6, passing through an hospital, in a town, quite a big one, named Rome.

It's just that parents nowadays forgot that kids are functioning humans, can learn stuff and can do stuff on their own.

As someone living in the netherlands, primary use is for decoupling risk. Look at the pedestrian side, they only cross a single lane where they have to look in a single direction. This makes pedestrian behaviour so obvious that its hard to miss someone looking straight at you while you're crossing. Same with car behaviour, no matter where the car is, the nose is pointing straight at you before crossing the conflict zone. The line of communication you have before a potential accident is insanely useful. It does not matter wether a stop sign or right of way was there if you're dead.

The "buffer" reduces decision complexity even more because people treat them like train blocks. The only annoyance I have is when people actually break-and-check at these points even though its better to roll the car slowly trough to save the people right behind from brake checking entire queues.

I saw a lot of this when I went to college for engineering, some professors had this ability (or willingness) to make hard things simple, and others did the opposite, it was the same with the books, I dreaded the "exercise for the reader" shit, I don't think I ever did any of those, so those were all proofs I never got.
My best friend was like that. Couldn't see the practicality until he got bit by a geology and water science bug. He went from calling me to get help figuring out percentages to doing chemistry equations in his head because he "got" the applicability.

My brother's mom tutors math. One of her insights with a former student was that they were in need of forming some number sense. She started by walking them both out to the street: "how many tires are there on this street of parked cars?" The student, already flummoxed, started panic guessing. So she started with counting.

For times tables, have you developed any intuition around it? For me, times tables are rectangles composed of unit squares and that helps with my intuition. Modern Common Core standards in the US focuses a lot on exposing different mental models to students. And after seeing the same 4x6 enough times your brain will automatically associate that with its solution. Instead of calculating, it is memorized.

My brain doesn't require car tires, geology, or other practical needs: it likes puzzles. I struggle with medical stuff and I can feel my brain switching to meh-mode and hardly anything sticks. I don't know how many times I have been told about the different kinds of sugar and how your body uses that energy and I would still have to look it up.
It's 'not progressive', but that might not fly in the US.

- Lots of HTTP tooling built in.
- Fast.

- Great language.
- Great code reuse system: Modules.
- Nice framework: Django.
- Less breaking changes in recent years.
Even better, the gemeente is actively converting streets into fietsstraat. It is amazing and I love it. It makes my commute through the city so much faster and less stressful. When they did the knip experiment on that big through-road near Waterlooplein and there was no car traffic, it was also fantastic. At that time, I was commuting that direction and it was wild how quiet that part of the city became. Cars really are a terrible nuisance and do not belong in the city.

I think it would be actually the other way around - Starlink orbits aee low enough to be self cleaning & Starlink satellites can be (and are) rapidly replenished. So even if something from up above hits anfew, the debris would deorbit soon & new ones could be launched.

With GEO sats, unless you go for direct GEO insertion, it might still have issues reaching the final orbit. And even at GEO, there could be a debris cloud as well causing issues, at least until the sun and moon gravity perturbs it enough.

Let's say she was testing the moderation system on a different topic. For example she'd posted the statement "Jesus was nothing more than a man", which resulted in her post being instantly censored and her profile slapped with a content warning.

Would you still be making the claim that she is "spreading hatred"?

I would still say she was making a factual statement that she was censored for. As we have evidence that this person was a historical figure and not just some figment of fiction. Only those with a particular ideological belief, i.e. most Christians, think there's more to it.

Fortunately that's not what happened, and such ideologues are not in charge of imposing those beliefs on others via Bluesky's moderation system. But it's clear that those who assert that some men are women are imposing their beliefs. Which is exactly what Sall demonstrated.
"As if it's gone"? Is this a joke?
In general, separate bike lines are nothing special in the Netherlands, even in Amsterdam. However, it's an old, compact city with narrow streets, so you're unlikely to see these types of intersections in those streets. Same is true for other old city centers with compact layouts.

You're more likely to see this if you go to places with more space, such as suburbs built in the last century (which basically means going to another town or city that Amsterdam grew into, because in the Netherlands city distribution is also compact). As you can see from the picture this street is in such a neighborhood.

Also, the general concept of having a distance of one car between crossing and bike lane is universal whenever there is space. I can give you a personal anecdote (at the cost of doxxing myself). I grew up in Oldeberkoop, a tiny village with around 1500 people in it that somehow has its own wikipedia page[0].

Just outside of the village is a crossing with an N-road, which is Dutch for "provincial national road but not quite highway". In the early nineties it was still a simple crossing, no separate bike lanes, and I recall traffic accidents happening once or twice every year. For context, nowadays the speed limit on provincial roads is 100 km/h[2], although in the early nineties it was still 80 km/h. That didn't matter though: everyone was speeding as if they were on a highway and going 120 to 140 km/h.

In mid nineties the crossing was changed to a roundabout, solving the speeding problem, and separate bike lanes were added (this also reduced traffic noise a lot). In the early 2000s the roundabout was changed to the safer design described in the article: more space between corner and bike lane, and a bigger island in the middle of the road for pedestrians[3]. I haven't heard of any incidents in the years since.

Recall: this is a village of 1500 people. When the article says:

> I would like to emphasise that this intersection is not special in any way. You can find many similar examples all over the country. That is because the design features stem from the design manuals which are used throughout the country.

... it is not exaggerating. This is the norm with any new intersection that is being built, or any existing one that is due for its two-decade maintenance.
