I think it depends on the specific traffic expectations, a roundabout interrupts the traffic flow of everything that feeds into it... the double diamond can prioritize a more uneven flow in one direction (so might be better in cases where lots of people travel in one direction, like rush hour)

Might also be worth mentioning that Americans seem to be really bad at using roundabouts because they're not common in much of the country.
Yes, it turns out that it is rare for mass-produced mechanical devices like record players to spin at exactly the rate they are supposed to (eg 33.3 or 45). Or they can drift put of calibration over time. Often they will be a few % off or worse for really cheap players. Usually there is a way to adjust calibration by turning a small screw someplace on the machine.
> I don't know anyone that has an empty room in their house, or one that no-one enters for weeks at a time, etc.

I don't have any statistics to hand but, based on experience, there are a lot of houses in the UK like this. Particularly among middle class couples in their 60s, whose children have left home. In fact, my parents have two spare bedrooms that are only used a handful of times each year.
Actually, chatgpt says that for 1mm resolution you need 9 decimal places anyway :-) Note a rtk gnss can resolve your location to 1cm. I don't know how much jitter there is in the USB buffering, but for this purpose, lets assume 0. Then if I want to do experiments with short distance localization then it would be good to be one decimal less than what I want to use in practice, so there is the 1 mm. So I could format this to a max of 9 decimal places. I see the above is still a little more. Something for the next time I make a push. Thanks for your concern :-)

When a prediction has a probability attached to it, it should be possible to check the math. In some sense it isn’t really a prediction about the future, so much as a statement about current information (which is not complete).

Or, possibly, they are using “90% confidence” colloquially as “pretty sure.” If so, that should probably be made more clear. He’s using the fact that the researchers agree as an argument from authority, which is doubly wrong if the apparent authorities here were just giving their hunches.

I disagree. I've seen poling and heard numerous stories of citizens of sanctuary cites that were not border cites and have a very negligible issue with illegal migration suddenly having to deal with it first that shows that trucking migrants has moved the needle.

> Since it is not, downsizing your home in retirement to release space for bigger family will be more efficient than building everyone a house with a spare bedroom.

This is true. The problem tends to be that people become settled in an area, and would prefer to downsize there so they don't need to uproot themselves. This is often very difficult, as there may not be availability in that area for a suitable smaller property.
DJ turn tables have a pitch fader and lights for calibration: https://www.youtube.com/watch?v=KbdK94vl_Bs.
For context, that's a very specific kind of roundabout that you find near the junction of a motorway (the M1) with a primary road (the A630). The roundabout is situated on the A-road and accessed from the motorway by a slip road. That way, motorway users who don't care about the junction can just keep cruising forwards and drive over the top of the roundabout. Nevertheless, drivers can approach from any direction and exit in any direction (including back the way they came). It doesn't look like this is the case in OP's article; I'm not sure how someone approaching from the left can continue in the same direction and drive off to the right.

Roundabouts generally look more like this in the UK (without any overpassing roads): https://www.google.com/maps/place/Howarth+Ln,+Rotherham/@53....
Even a cheaper record player will often have some kind of adjustment on the motor itself. There is sometimes a small screw on the motor that can do some fine adjustments of the speed.

Belts age. Friction within the motor and the table's bearing will change over time. It is not necessarily a frequent thing that needs to be done, but usually the speed will change slightly over the life of the table.
That's clever. They had just better be 100% on top of maintenance. I can see that interaction at crossover being non-fun with say faded markings.

$6B seems like not enough ? Google, meta have spent far more, and have less to show for it than openai (which has also spent more).
The irony being that (from a UK perspective at least), in the absence of immigration, childcare and senior care would be even less affordable than they are.

Somebody has to do this work: it's essential, as well as hard, unglamorous and badly paid, and societies must take their pick from:

- Family members, almost always women, who have to give up paid work.

- Paid labour from less educated parts of their existing/indigenous population.

- Migrant labour, whether temporary or permanent.

The great mistake of Brexit is that the UK has now replaced temporary migrant labour (Poles and so on, who'd mostly come here in their early/mid 20s, stay for ten/fifteen years and then go home to raise families and be closer to their elders) with permanent migrants from much poorer countries who won't want to go back if they can at all avoid it.

Show HN: Your Next Store – E-Commerce with Stripe as the back end
Michał and I are building Your Next Store, a modern Next.js boilerplate for creating online stores directly on top of Stripe.

While working on several e-commerce projects, particularly building storefronts for enterprises, we realized that many small to medium-sized stores could benefit from a simpler, more efficient setup. Stripe provides most of the tools needed for e-commerce, but we noticed a gap in how these tools could be easily integrated into a modern, high-performance storefront. That's why we built this boilerplate.

Your Next Store allows you to create an online store with Stripe as the backend, eliminating the need for an additional database. Products are stored in Stripe, and all operations are managed directly through Stripe, significantly simplifying the backend. This setup is ideal for small, maybe even medium-sized stores looking for an easy-to-maintain solution with fewer moving parts.

- Direct Integration with Stripe: Stripe as your backend, eliminating the need for a database or CMS and reducing complexity.
- Next.js Performance: Next.js as the framework offers great defaults for both productivity and performance. It's also more flexible and easier to customize compared to something like Liquid :)
- Simplified Maintenance: Fewer moving parts make it easier to set up and maintain compared to more rigid solutions like Shopify.

The project is on GitHub, and we decided to sell access to the codebase to support ongoing development and respond to feature requests.

They don't explain how they fix even one of the problems they mention at the top. Maybe I'm missing something here but this is just pure marketing bleh.
"authorization" and "authentication" are poor stupid choice of words.

They are long, not easy to pronounce, sound too similar, have the first 4 and last 5 characters the same, they mean wildly different things and yet get interchangeably used as "authn".

If i give you keys to a room with the number 101 on it, is that authentication or authorization, or none ?

If a gatekeeper says "sorry, invalid auth", what the f does that even mean?

An expired token, is that authentication failure or authorization error?

What about fake token ? A token with valid signature but wrong audience ?

Its such a fu*ing mess.
It’s not so ridiculous once you learn that most of the earths crust gets recycled within 500 million years, and more than half gets recycled within a mere 100 million years.

That’s why we don’t find fossils everywhere. And if humanity goes extinct today, it would be fairly tricky to find evidence of us in a billion years.

It’s of course a non falsifiable hypothesis, so there’s not much we can do. But plenty of people believe in another non falsifiable hypothesis——invisible man in the sky.

> These non-human corporate entities don't have a real incentive to leave the houses empty.

They may have such an incentive. In an idealized market where everyone has perfect information, they wouldn't, but we don't live in such a market. In practice, it may be more profitable to leave a house empty to drive up rent on your other properties, and to save the maintenance costs that tenants would bring, especially if you can indirectly coordinate with other large property owners: https://www.propublica.org/article/yieldstar-rent-increase-r...
What are these mental gymnastics, and why are you bothering with them?

If you're being sarcastic, it's not coming through over the internet. It sounds like either a variant of "might makes right", or irrelevant linguistic pedantry.
The study you linked to doesn't find heredity to be the driver of decline of IQ (which they pointedly reminded is not a measure of intelligence):

Regardless, we believe education, test-taking, and media exposure emerge as potential moderators for explaining the observed gains in three-dimensional rotation scores and declines or stagnation in matrix reasoning, letter and number series, verbal reasoning, and composite ability scores.
So you have multiple speed settings (33.3RPM, 45RPM etc.), but most if not all players also have a little adjustment knob to tweak those settings more precisely.

Good players will have it on the front, and will have a strobe to help you adjust that (the little dots you see on the outside of the platter on fancy players). However, cheaper players may not have an easy way to adjust, and some (like mine) hide the knob under so it's a pain to adjust.

Cheaper players are more likely to come misconfigured from the factory. I asked a lot of friends (who are amateurs, not audiophiles) to test this app out and every single one had a turntable that required adjustment. Mine's running at 34.6 RPM which is just 3% off, but when listening to my favorite albums I can definitely tell that it's too fast and too high pitched.

The speed will also sometimes drift slowly over time, which is why it took me a while to notice my table was off.

If you have a turntable, you can try listening to the same song from a record and from a digital release, and see if you can hear a difference. If you do, I know just the app for you!
How hard would it be to just build a pedestrian tunnel underneath it and avoid the problem altogether?
Housing is such a unique thing that I think it should be treated differently when we talk in terms of 'capitalism', 'public services', etc. Everyone needs a house. Nobody can use more than one house simultaneously. Houses are incredibly expensive, but most of that cost is purely market-driven. Housing is, essentially, a zero-sum game.
I tried it out and the instructions have tips on what record to pick, they say to pick a well known version of a song (like not a live version etc), and preferably song with a beat, but it says it doesn’t use any 3rd party APIs or libraries, only Apple APIs. So my guess at to what it’s doing is using a ShazamKit recognition behind the scenes and looking at the frequencySkew value of the matched result. It also gives you one answer after listening, instead of a continuous gauge, which seems to corroborate song recognition. It probably won’t work with an obscure record that is not Shazamable. And so I don’t think it can measure wow & flutter as a result.

Still pretty cool for those that need to calibrate a turntable, or verify 33 vs 45 PRM for a record.
Yes. This has already been demonstrated by "Teaching Arithmetic to Small Transformers" https://arxiv.org/abs/2307.03381 , I'm not sure what OP adds except demonstrating that you can do that via the embedding itself rather than the tokenization.

> We first demonstrate that conventional training data is not the most effective for arithmetic learning, and simple formatting changes can significantly improve accuracy. This leads to sharp phase transitions as a function of training data scale, which, in some cases, can be explained through connections to low-rank matrix completion. Building on prior work, we then train on chain-of-thought style data that includes intermediate step results. Even in the complete absence of pretraining, this approach significantly and simultaneously improves accuracy, sample complexity, and convergence speed. We also study the interplay between arithmetic and text data during training and examine the effects of few-shot prompting, pretraining, and model scale. Additionally, we discuss length generalization challenges.
Is this really an appropriate use of arxiv? I thought it was for physics preprints. This might be a neat work, but it appears to be a 143 page blog post in a PDF (unless I missed the references section?)

They simply don't think studying or learning is cool and are more interested in gossip.

1873 - caused by land speculation, driven by railroad companies and their investors

1929 - caused by a stock market bubble

2008 - caused by widespread mortgage fraud and speculation on the housing market

Thanks for sharing this. I do a lot of work in this area and I had not come across PASETO before. It is an exciting project.

The nonce is especially nice because it makes the token high entropy enough that if only the signature leaks an attacker can't brute force the full token. This isn't always true in OIDC JWTs.
I think you are mixing layers of abstraction. To make a crude but I think not unhelpful analogy: 'Understanding' is a natural language concept that is our way to describe whats happening in our heads, and like most other such concepts is resistant to any clear definition and will exhibit sorites type paradoxes when one is attempted. It belongs to the presentation layer of the stack. While the process of curve fitting, however it is implemented, with whatever NN structure (like transformers) or maybe something else entirely belongs to the physical layer of the stack -- akin to frequency modulation.

While I am unsure whether LLMs are really understanding, whatever that means, I think it is not difficult to believe that any form of understanding we implement will involve 'curve fitting' as a central part.
Again not really. If the pub/sub broker is persistent, you don't have to persist the revocation list on edge nodes.

> Housing is an inelastic good - particularly for demographics who have limited access to transportation and therefore need to live very close to where the jobs are. The price increases until it consumes all the money available to pay for it.

Housing is not rising in price because it is an inelastic good. Housing is rising in price because the growth in the supply of housing is less than the growth in the demand for housing.

Indeed, the very fact that housing has inelastic demand means that it is particularly susceptible to price reductions when supply is higher than demand.
