Nah. Most agencies have a problem of people realizing that wasting life in buses is not worth it.

Transit can never compete with cars on speed in well-designed cities.
>Still mostly anecdotal

In principle, what sort of hard evidence is gathered that could establish the point?
Note that diesel is taxed nearly 40% higher than gasoline per gallon in the US. And shipping trucks use a lot more gallons of gas (total and per mile).

Should the rate be higher? Perhaps. But it's already a bit slanted towards vehicle weight based on fuel type and consumption.

Electric vehicles, and especially electric shipping trucks, are going to require finding new taxation sources.
> LLMs are, at their core, search tools.

Fundamentally, no they're not. That is why you have cases like the Air Canada chatbot that told a user about a refund opportunity that didn't exist, or the lawyer in Mata v Avianca who cited a case that didn't exist. If you ask an LLM to search for something that doesn't exist, there's a decent chance it will hallucinate something into existence for you.

What LLMs are good at is effectively turning fuzzy search terms into non-fuzzy terms; they're also pretty good at taking some text and recasting into an extremely formulaic paradigm. In other words, turning unstructured text into something structured. The problem they have is that they don't have enough understanding of the world to do something useful that with structured representation that needs to be accurate.
Except with inflation almost everyone applying to a top school has perfect grades. So it’s not a factor.

It's called mineralization, and happens so long as there are dissolved minerals in the water and PH is correct. Lead contamination happened in Flint, MI because additives to control the water PH were neglected to save cost, and slightly acidic water ate away at the mineralization layer in the pipes and began dissolving the lead again.

I completely agree. In graphics programming, I love having it do things that are annoying but easy to verify (like setting up frame buffers in WebGL). I also ask it do more ambitious things like implementing an algorithm in shader code, and it will sometimes give a result that is mostly correct but subtly wrong. I only have been able to catch those subtle errors because I know what to look for.

4-7-8 breathing or similar is a nice option (breath in 4 seconds, hold 7 seconds, out 8 seconds). I find 2 minutes helps you get into it more than 1.

This also gets to my criticism with inflation. The basket-of-goods used to measure inflation can have wildly different outcomes based on what we’re trying to measure. Bread may be 10% more, but health-care might be 500% more but a computer might be 25% cheaper, while being higher quality.

The military measurement Noah is describing here is a different independent variable but just as valid as any other cost variable, putting a nuclear-armed North Korea and Israel in a global stage, likely causing other countries to do the same.

They rapidly expanded the LMIA program which provisions visas for primarily low income work.

Additionally they realllly expanded the international student visa pool, without actually checking who they were granting visas to.

The result was that pretty much non existent colleges were created with the sole goal of allowing people to pay for a backdoor to try and get PR without high level education, skills or even language proficiency.

Lastly there used to be a cap on visas issued based an unemployment rate of 6% they removed that cap so despite unemployment being up to around 10% in major cities they are still granting tons of visas.

So yeah... They really went out of their way to expand the visa program as fast as possible with very little oversight.

Additionally in terms of actual background checks, those seemed to go out the door as Canada in the past few years has given PR to a number of people who are actively wanted terrorists as part os Isis and other terror groups

Time intervals aren't floors or rounds but thresholds.

This is most evident above the level of hours, minutes, or seconds: we speak of a new day beginning (though the time at which this occurs has varied culturally and regionally), or a new year, decade, century, or millennium (with their own threshold arguments courtesy the AWOL Year Nil in the Julian/Gregorian calendrical system).

Birthdates are an interesting example. In Western/European cultures, it's typical to count by full years elapsed, such that an infant within its first 12 months is 0 years old. In Asian cultures, the age is given as "1", which is reflected in an occasionally-used Western notion of "being in my nth year". That is, a 49 year old is in their 50th year.

What a clock (or calendar) indicates generally is what time period you are presently in, that is, the second of a minute, the minute of an hour, the hour of a day, day of a month, etc., etc. And what's relevant from this point of view is that the threshold is what matters.

The other problem touched on in this essay is of estimating time remaining to a future threshold, and here, rounding is indeed useful. If you have a 10am meeting and the time presently reads 9:55 am, you have fewer than five minutes to arrive punctually. But that is planning and not timekeeping issue, strictly.

Congestion pricing should really be referred to as a "lower manhattan driving tax" or similar. It's a misnomer to claim it to be "solving" congestion outside of rush hours like 7-10 and 3-7.
I've thought about the same thing and concluded this basically reduces to "why do economies organize around dense urban cores"? pretty much any business that can afford to will want to rent space in the barycenter of a metro area. that's what manhattan is to the NYC metro.

when the vast majority of daily trips are into and out of that dense core, that defines the most economic routes for building transit. beltways/bypasses exist to relieve the already saturated surface roads of the core. you don't see the same thing with trains because it's not necessary. it sucks for the passenger to transfer between three or four different trains to get from EWR to flatbush, but the rail infrastructure has plenty of capacity to accommodate a few extra pax on that route.

I think it would be a lot nicer to have urban life/transit built around many smaller cores with everyone living much closer to work. but in aggregate, businesses want the largest hiring base, and people want the best jobs they can get in the area.
I find it hard to believe that atmospheric lead levels were higher in the ancient Roman Empire than since the Industrial Revolution. The amount of lead mined and smelted now is vastly more than it was then. Regardless of current safety measures, there were decades with none. And then we had leaded gasoline for a century.

Everything in this article may be accurate, but that likely means we're all far worse off now.

One of my fondest memories is from when I was in university and one Xmas break my stipend was late for a few weeks and I completely ran out of money. All my dorm-mates were away for the break so I had no one to borrow money from. I scrounged around my dorm and found a fistful of loose change — it came to around $2.30 iirc. Bought a bag of rice and frozen peas and managed to last about a week. “Free” takeout soy sauce packets were a big plus. Good times.

The process-centric taxonomy in this paper is one of the most structured frameworks I’ve seen for anomaly detection methods.
It breaks down approaches into distance-based, density-based, and prediction-based categories.
In practice (been doing time series analysis professionally for 8+ years), I’ve found that prediction-based methods (e.g., reconstruction errors in autoencoders) are fantastic for semi-supervised use cases but fall short for streaming data.

> reducing their IQ by 2.5 to 3 points

I seem to recall reading an article that observed that every time we do a study of the effect of lead exposure on IQ, it gets larger.

IQs aren't changing much, but lead exposure is going down, and so we keep imputing the same IQ gaps to ever-smaller quantities of lead.
Why specifically call out fluoride?

I don't live in SF, so could definitely be some local nuances I'm missing. in NYC, there is a pretty clear partisan split on the new congestion tax. the (relatively) red leaning areas are the loudest opponents. I guess having so many high earners already taking public transit might change the discussion.
I haven't read it, but the book History of Toxicology and Environmental Health [0] would say that pipes were not a problem. Preparing food and wine in lead containers could have been a problem, but it wasn't until centuries after the Roman Empire "fell" that doctors even described the symptoms of lead poisoning.

And to throw in another quote from a scholarly source, "Water from the river Anio, which fed two of Rome's principal aqueducts, the Aqua Anio Vetus and Aqua Anio Novus, was particularly hard and conveyed high levels of dissolved calcium carbonate. Indeed, Frontinus complains in his treatise on the aqueducts of Rome, that "the accumulation of deposit, which sometimes hardens into a crust, contracts the channel of the water" (CXXII.1)." [1]

This was the cause of the panic, though. In the 2021/2022 time-frame many businesses that would normally only pay the minimum wage, give irregular hours, and treat people pretty woefully were forced to pay well above minimum wage.

My little son has a buddy who uses AI bots intensively. The friend is actually very smart and capable, but he pays too much attention to the things he likes (programming and games) and ignores all other aspects of basic education. And he slips, mindlessly copying what the bot tells him. If this is a widespread trend, it's obviously very worrying, especially for young students.

On the other hand, we have had many discussions with my son about the role of education, AI and what we need. Thankfully, my son understands that it's the struggle that we go through that helps us to understand and make the knowledge truly our own. Of course, I have to model my use of AI, pointing out its flaws and the dangers of mindlessly using bots.

At the end of the day, it's the internal motivation that drives us. If you're not interested in knowledge and learning, having a genie to cheat is too tempting to resist.

Indeed. Personally, I wish we could have that kind of content, but edited to remove the filler (redundancy, time spent reasoning out a position) while still accurately representing nuanced views and the evidence for them.
Unless your network is poor, I’d imagine (but definitely could be wrong in your case!), the bottleneck is the LLM speed, not the latency to the data center its running in.
I was imagining something a bit more impactful (and easy to find in the data), because as far as that one goes, it's not clear why anyone should know or care.

Maybe high school graduation rate (an inverse proxy to indicate bullying)?
Heh. I think it’s more likely most people saying that don’t really know what it’d entail.

For instance without our current banking and financial system you’d have to pay banks to look after your money, if all they were allowed to do with it was hold on to it. This would have a similar drag on your principal as inflation does on buying power.

It's a bit of a thing with a particular political persuasion in the US right now (RFK Jr has made his anti-fluoride position a big part of his deal for his future role as Secretary of Health and Human Services), and there was a report in the news recently that some see as backing up the claims against fluoride:

https://www.latimes.com/science/story/2025-01-06/what-a-new-...

It's not as conclusive a study as some people might claim, though:

> For starters, 52 of the 74 studies were judged by the report authors to have a “high risk of bias.” That undermines the validity and reliability of their results.

> Another issue is that most of the studies considered fluoride exposures far above the target level for the U.S. ... Only seven of the studies assessed children whose water contained less than 1.5 mg/L of fluoride. When they were considered on their own, there was no relationship between fluoride exposure and IQ.
It's a shame to see they max out at just 32GB, for that price in 2025 you'd be hoping for a lot more, especially with Apple Silicon - while not nearly as fast - being very usable with 128GB+ for LLMs for $6-7k USD (comes with a free laptop too ;))
Lead contamination is still fairly widespread: carrots, sweet potatoes, chocolate, spices. It’s a good idea to get your blood tested and try to find any sources of exposure if your levels are high.
