> Around 90% of superstar adults had not been superstars as children, while only 10% of top-level kids had gone on to become exceptional adults (see chart 1). It is not just that exceptional performance in childhood did not predict exceptional performance as an adult. The two were actually negatively correlated, says Dr Güllich.
Even if "only" 10% of elite kids go on to become elite adults, 10% is orders of magnitude larger than the base percentage of adults who are elite athletes, musicians, etc. This doesn't sound "uncorrelated" to me so much as "not as strongly correlated as one might expect."
And describing something that happens 10% of the time as "rare" sounds a bit weird, like referring to left-handedness (also about 1 in 10) as rare.
It's like those articles that say super high IQ people are not always successful.
So I think human brain development is like some kind of optimization algorithm, like simulated annealing or gradient descent. I think this because there is way more complexity in the brain than there is in human DNA, which has pretty low information by comparison. Anyway, child prodigies occur when the algorithm happens to find a good minimum early on.
I don't get it - afaik you can get every single part of a gun except for the lower receiver/pistol frame without any restriction - as those parts are legally defined as the 'gun' - the rest are just replacement parts.
Even for those, you can get 80% finished parts for those - just drill a few holes, and file off some tidbits, and you get an almost factory-spec gun.
I'm no expert on US gun law, but afaik, some states even allow you to make your own guns without registration, as the law defines gun manufacturing as manufacturing with the intent of selling them.
So there's plenty of options, many of them better than making a gun with a printer.
But even all this is typically overkill, I dont think criminals go to these lengths to make their own guns, they just get them from somewhere.
The receiver is like the asset tag on computer servers- it's the one thing that is definitely not replaceable since it has the serial number used for entitlement.

In an industry where everyone sells a completely fungible product such cost savings generally are passed on to consumers. Oil companies can profit in the short term due to fluctuations in the price of oil and things like that, but not from something like lead additives, which everyone had been using for decades.
If the end product ends up marginally cheaper, the company will be able to sell more of it, and this will lead to more profit. And sure, when you ignore the cost of the pollution, this certainly benefits the consumer, by allowing them to afford more energy and energy-based products (i.e., just about everything).
But then we come back to ignoring the cost of the pollution. It certainly gets paid for eventually, but by who? Also, it's cheaper for everyone if the pollution is eliminated to begin with rather than being cleaned up later (which is certainly a more energy intensive endeavor).

We had research to support the EPA phase down of lead.
Also, your assertion that lead “helps fuel companies” is fundamentally mistaken. Gasoline is a mass-produced commodity. Oil companies have single digit profit margins. These companies aren’t making Big Tech profit margins where they can absorb higher costs without passing them along to consumers. Cost savings from things like gasoline additives accrue to consumers at the gas pump.
Lead helped fuel company profits because it was cheaper than the other anti-knock additives, like ethanol.

The shortest double-to-string algorithm is basically Schubfach or, rather, it's variation Tejú Jaguá with digit output from Dragonbox. Schubfach is a beautiful algorithm: I implemented and wrote about it in https://vitaut.net/posts/2025/smallest-dtoa/. However, in terms of performance you can do much better nowadays. For example, https://github.com/vitaut/zmij does 1 instead of 2-3 costly 128x64-bit multiplications in the common case and has much more efficient digit output.
I have been using Walter Bright's libc code from Zortech-C for microcontrollers, where I care about code size more than anything else:
https://github.com/nklabs/libnklabs/blob/main/src/nkprintf_f...https://github.com/nklabs/libnklabs/blob/main/src/nkstrtod.chttps://github.com/nklabs/libnklabs/blob/main/src/nkdectab.c
nkprintf_fp.c+nkdectab.c: 2494 bytes
schubfach.cc: 10K bytes.. the code is small, but there is a giant table of numbers. Also this is just dtoa, not a full printf formatter.
OTOH, the old code is not round-trip accurate.
Russ Cox should make a C version of his code..
This is by far one of the best advertisements for LUKS/VeraCrypt I've ever seen.
Agree, use Linux, use LUKS.
PGP WDE was a preferred corporate solution, but now you have to trust Broadcom.
EDOS was a direct 6800 port of FDOS. FDOS was the first DOS available for microcontrollers, using iCOM's FD360 8-inch floppy drives.
