I'm getting older too and the last thing I need is more blurriness.

i get enough natural, organic blurriness from my presbyopia after 40

Trees are great but Las Vegas is in a desert. It would better to also build for shade, like old hilltop towns in Italy or Spain, or various urban designs in the Middle East.

None of this would have happened without the support of Silicon Valley billionaires.


Milwaukee started its shade program in the 1980s.


Looking at the graphs it appears that two people had big improvements and the others not very much.


Going to bed a lot earlier. Some people just can’t sleep past a certain time no matter what.


Practice will clearly improve your performance on puzzle questions like these. Is that really testing intelligence, or just interest and motivation for solving puzzles?


It's also testing for social class, educational quality, and attention span. While mostly validating existing hierarchies. And giving loads of people a reason to feel good about themselves.

Really, what's not to like about IQ tests?


Don't forget the very real and horrifying links with eugenics and the use of IQ testing to justify sterilisation and worse! It's the gift that keeps on giving.


Not just that. Some IQ test puzzles that were difficult to understand when I encountered them "in the wild" went from bizarre to somewhere between trivial to doable when I read an explanation online of what they were even asking. My measured IQ would have taken quite a jump on just that one bit of information, were I taking those tests.

Without sarcasm or rancor, you can profitably debate whether or not that means that those questions were just too hard and I really was indicating that I wasn't smart enough for them. I get that, and my point isn't about my intelligence or if it is measured properly; whatever it is, it is, and you are welcome to conclude that I'm just a dufus, especially if you get them without that hint. My point is more that if the tests are supposed to be good measures of whatever intelligence is, it is rather debatable whether they should have that characteristic.

I do know I have never liked the "find the next number" tests; even before I learned about polynomial interpolation in school my protest has always been that any series of any numbers can be a pattern; there are an infinite number of patterns, and even constraining them down to the "human interesting" patterns isn't enough to nail down the patterns the IQ test writer is actually using. As a passing part of this post [1] I show a number of patterns in the OEIS that start with 1, 2, 4, 8, 16 and do not proceed to 32, each of which does not proceed to 32 with a different number, and I just stopped looking after I had enough for a blog post and already was filtering the results to "things you might actually recognize", and I probably could have kept going for a while. (Yes, I'm aware that a normal IQ test won't be looking for "divisors of 496" at the beginning parts... but towards the end of a high-IQ test...?) Just realizing that they tend to confine themselves to varying levels of Newton's calculus [2] is enough to unstick me, and, again, bump my score just because I know something rather than because of "intelligence".

(This also implies that the SAT proxy measure, even though it is not a direct IQ measurement, is likely to be more satisfactory, in the cases where the test takers have the relevant mathematical knowledge in advance. The SAT did not involve any problems that I had not encountered before, and to the extent that I passed and failed the various questions it can not be said it was due to lack of knowledge of what the questions even properly were on my part.)

Yeah, these are awesome. It’s SUVs that are ugly.


…and dangerous!


I used pinboard for years until I started saving web pages as PDFs in my Dropbox folder. I got the idea from pinboard’s own archive feature.


People used it to organize an attempted coup against a democratically elected government and twitter is not cooperating with the investigation.


Someone from Brazil said they have no rule of law right now, they have a dictatorship. So Musk would be complying with a despot, not the law enforced by Brazilian representatives.


It was a protest. There was no coup attempt. A coup attempt would be the military launching the operation to seize power and failing. An actual coup would be the military trying it and succeeding.

They didn't try to seize power for themselves. They wanted the military to seize power so it could rule them instead of the elected president. There's a difference. They thought the military would be better rulers. That's just their political position.

There's simply no way you can convincingly claim that a bunch of people, many of them elderly, equipped with bibles and brazilian flags, tried to seize power in the brazilian capital. This country is pathetic but it can't possibly be so weak that it could suffer a coup by people like that.


I don't see how that argument would leave coffee shops and other gathering places able to stay open during elections.


Coup not election and if they don't cooperate with an investigation of an attempt to subvert the election with violence, they might not.


Coup without firearms. How does that work? Are the people supposed to shout their lungs out until the government decides to step down cooperatively?


Bloodless coups are a thing.


I’m reading some more and the election interference happened under Jack Dorsey‘s Twitter not Elon Musk’s X. The Twitter employees involved were fired in the purge after Musk bought and assumed control of the website.


I’m pretty sure that’s the CIA’s job. Isn’t it because Brazil doesn’t have free speech so they have absurd “hate speech” laws similar to the ones that are backfiring in Scotland right now?
