The iron from meteorites has a very different chemical composition compared to iron extracted from terrestrial minerals. More specifically, the iron meteorites are made of an alloy composed of iron, nickel (5.7% on average), cobalt (0.28% o

I stopped using swap almost a quarter of century ago, and since then I have not seen a PC with Linux freezing because of full RAM. Before the recent increase in RAM prices, it was not difficult to have a generous amount of RAM in a PC, that

One could design a mirror life form that uses mirrored amino-acids to build its proteins and also mirrored carbohydrates as building components, but which would nonetheless also have enzymes for the hydrolysis of normal proteins and carbohy

Eating enough protein is also important, especially for older people, to prevent the loss of muscular mass, but that does not change the fact that the food must also include enough "fiber". The US had for a long time a much too lo

Their is no doubt that for millions of years the humans have eaten much less fiber than their ape ancestors. You just have to look to the belly of a healthy, non-obese human and compare it with the bellies of the apes. The bellies of the ap

"Fiber" is a vague term that is used for the carbohydrates that cannot be digested by humans, so they reach the large intestine, where they are fermented by bacteria. This includes a part of the "resistant starch", which

You cannot compare it in general, but in a particular case you can very well compute it so you can determine whether you have spent well your energy, or you have wasted it because using it otherwise would have produced more hydrogen. Even i

LLMs were not available in 2021, but "Google translate" is much older. Such translations were not unusual. Around 2017 to 2019 I used a lot "Google translate", because it saved time despite its flaws, but there never was

USA exports a lot of oil, but that cannot be used by the US oil refineries, which need to import oil, or take it from reserves. Therefore USA is not oil independent, despite being a net exporter.

It is not so simple. Tai Chi, like many other exercises that have been derived from former martial arts, is a complete exercise, for all muscles and articulations, especially when one of the older long forms is practiced, not one of the mod

I agree.

The fact that a martial art technique is a guess invented right now to explain the origin of some Tai Chi movement does not mean that it is a bad technique. If the one who made the guess is competent, it may be an excellent technique. Howev

More accurately, it was a martial art in the 19th century, when it was practiced by professional bodyguards, but that did not resemble much what is today called Tai Chi. What is practiced today is a health-preserving exercise derived from t

That is false. All the claims of the RISC-V fans that I have seen in the past compared the compressed variant of RISC-V with the uncompressed variants of the other ISAs. Most other ISAs, like ARM, POWER and MIPS, also have compressed varian

The combined comparison-branch instructions of RISC-V are its only good feature in terms of instruction encoding design. This allows a significant code size reduction in comparison with ARM Aarch64, but unfortunately for RISC-V this advanta

For those less familiar with x86, the example instruction encodings that are interpreted differently on Intel and AMD are not base encodings, but instruction encodings modified with prefixes. The x86 ISA includes a great number of bytes tha

Designing a good 64-bit ISA, much better than RISC-V, is easy. There are thousands of people who could design such an ISA in a couple of weeks, without any AI assistance. The hard part, which has always been the moat of RISC-V, is writing a

You are right that they had pneumatic bones and air sacs and they were not as heavy as mammals with the same volume would have been. Nonetheless, the biggest dinosaurs were several times heavier than the heaviest terrestrial mammals that ha

The problem is that USA does not have any more rights than Iran to declare a blockade. If this will continue for too long, other countries may decide that they want to pass through the strait no matter what USA says. Then what will USA do,

The vision system has evolved to consider as white the average color of the environment. In terrestrial environments, the average color is typically not much different from the true color of the Sun. The white light of the Sun is split by t

The direct light from the Sun is yellowish, because the blue light of the sky is subtracted from it. If the sky is covered with clouds, then the light is white, because the blue sky light is mixed again with the direct Sun light. If the sky

The traditional solution for the problem of the repetitive data included in logs is that every time when a log file grows over a certain size (or periodically in time), a new log file is created and the old file is compressed with some stan
