I don't think you live anywhere close to the normal world. It's like saying "all my friends have phds". I mean, don't everybody know three languages and basic multivariate calculus?

We know that the quality of the astrocytes matters a lot. It's not just about the quality of the neurons or their number or the way they are connected.

I'm afraid we don't know much more than that yet.

We have created frankenrodents with human astrocytes and they are a lot smarter than their unfranked counterparts. I bet we could learn a lot if we repeated the experiment with astrocytes from humans with different, known IQs.

Front vs back vowels. Not much different from "cinco", "gigolo", or "gelato"/"ragazza".

Longer. Nuclear power tech was pretty good in the 60s (outside of the Soviet Union).

peterfirefly··on GLP-1 may slow biological aging
Not that easy unless you really try: shared IV needles and receptive anal sex without condoms (preferably repeatedly to really prepare the tissue). And you gotta find a willing donor who is not on modern HIV drugs.

peterfirefly··on I love software rendering
Modern "GPUs" have the ability to scan out from multiple buffers at the same time and do rectangular compositing during the scan out -- basically like a few giant sprites. It's got absolutely nothing to do with normal GPU work. Zero.

It lets a few unobstructed windows do animation without having to involve the compositor => lower latency AND lower energy use. They do NOT have to be full screen at all.

Oh, and they can also handle framebuffer formats that aren't RGB. This is very useful for video, as the natural format there is YUV or something similar. The YUV => RGB conversion step becomes unnecessary.

> had essentially their own processors to handle this stuff

Most of the benefit came from the sound card doing DMA from a memory buffer instead of using a high-frequency interrupt to have the CPU give it sound samples one or two bytes at a time (fetched from the very same memory buffer(s)).

More sophisticated cards could also do mixing of several sounds in "hardware" (usually by having their own little CPU do the work) instead of having the main CPU doing the mixing. Some of them could even play the constituent sounds at different speeds (Gravis Ultra Sound and Midi cards but the Midi cards usually had fixed sound samples). This mattered for more sophisticated game audio for a few years until x86 performance improvements made it irrelevant. DMA is still crucial.

which is precisely why they can get away with a library seemingly without having to specify or coordinate anything with the compiler.

peterfirefly··on Xi's 'death watch' will become a global spectacle
She would need the backing of both the European Council and the European Parliament to get a third term. That is extremely unlikely to happen. Moreover, the European Parliament can kick her out at any point if it really wants to.

There are also hard limits on what she can do as president. Brussels doesn't rule over the member states like Beijing rules over the provinces (Chinese + "acquired" ones). Most things need the backing of the Council (= the member states) + the member states can drag things out at home if they want to. The EU doesn't have anything like the US National Guard that can be used in member states to force them to comply (possibly against state laws and state constitutions).

The European Union is the consensus making cooperation machine many European countries have chosen to use and die Uschi is only in charge of one component of that machine.

Doesn't seem very rulery to me.

Harvard lost due to obvious "anti" racist discrimination. It still seems to discriminate against whites and asians and in favour of blacks, but not as heavily as it used to.

Edit: forgot to to write "and asians".

1959 was a long time ago.

Should we (the EU?) have sent weapons to the Venezuelan opposition in 1999? When exactly did Chávez become a dictator? He was clearly not a democrat (coup attempt in 1992) but I think it would have been premature and unlikely to have had good outcomes if we had done it in 1999 or 2000 (he was democratically elected both times). He was obviously a dictator when he died in 2013 but a large part of the Venezuelan population still hadn't cottoned on to it or they thought it was great.

Iran was similar. The crazies were quite popular in 1979.

Punishment is cheap and actually quite likely to work.

No, the money spent per pupil has a tiny effect (at best!) on outcomes.

There are also massive transfers involved (and the US has had them for at least twenty years) so the property taxes (in the US) have little to do with how much money schools have per pupil.

Often enough that high house prices can keep your kids away from most bad kids. I think it's a crude mechanism that still allows too many bad kids in and keeps a lot of good kids out. I don't like it. It's also the best available mechanism in many countries.

> If schools have lower taxes, their ability to attract good educators for children is reduced.

"Good schools" are mostly about avoiding bad kids and bad parents. Expensive homes (without Section 8 or equivalent in the neighbourhood) is a feature, as it keeps most of them away. It's not a good way of doing it -- it excludes lots of perfectly good kids and parents and it is really expensive. It's just the best way available to most people in the West.

No surviving Soviet Union and hence no Mao, no North Korea (and no Korean War), Viet Minh easily squashed, no Vietnam War (the American one -- but the one against the French would happen anyway). Half of Europe would not have been occupied by the Soviet Union.

And the Nazis wouldn't have lasted long, anyway.

peterfirefly··on Reducing undefined behavior in the C language
> in the times of very anemic compilers

These days, it's mostly taken as an invitation by very powerful compilers to sometimes do heroic optimizations (that we like) -- and sometimes screw us over in really obscure ways (which we don't like). We would really like to keep their ability to perform heroic optimizations and that's why there's so much pushback against eliminating undefined behaviour.

Many microcontrollers offer something a bit like that. There's typically a special part of physical memory that can also be addressed as bits using a separate address window.

> "you only taste salt on part X of your tongue"

I've never believe that one. I have sometimes eaten a little bit of salt in the form of grains and it was completely obvious that I could taste the salt all over the top of the tongue.

I cannot for the life of me understand how anybody ever came to believe something like that.

It's not like modern people don't have plentiful access to cheap salt, sugar, citrus/lime juice, etc.

> "glass is liquid"

This one makes a lot more sense but the belief that old glass panes in windows are thicker at the bottom because glass is liquid rather than it being an obvious consequence of the manufacturing method -- blow a glass bubble and cut it up and flatten the pieces -- also seems insane to me. It's on the level of Americans believing rail gauges are derived from the width of Roman carts and refusing to accept that people used (and still use) many different rail gauges.
