Sanctions for human rights violations would be justified only if they would be applied equally towards any country where certain human rights violations happen. Unfortunately, USA has never applied any sanctions equally against countries wi

It should be noted that, as seen at your link, at high forward voltages the characteristic curves of a vacuum diode do not look like those of a semiconductor diode, because the current saturates, which does not happen in semiconductor diode

One-index based addressing of items was the norm in most of the mathematics or physics books written before WWII, but even then there were exceptions, e.g. for the components of a quadri-vector or a quadri-tensor, i.e. for spatio-temporal v

I agree that something changed in the past ten years or so, because in the last few years I was surprised to notice on the street that almost everyone wears running shoes (in Europe). I have transitioned myself to wearing only some kind of

I do not know whether this has anything to do with any limitation in the WebP format, because it is more likely that this is some kind of bias in the kind of authors of Web pages who choose the WebP image format, who might also choose more

Already since Intel 8086, x86 has the instruction "INT vector_number", whose purpose is to allow software to invoke directly any of the many kinds of exception handlers or hardware interrupt handlers that are specified by the ISA

8" floppy drives were not compatible mechanically with IBM PC cases, but there were 8" floppy drives with their own enclosures and power supplies, which could be put on a desktop along the PC case. IBM PCs have never supported 8&q

Both Hepburn and the fact that English is deeply embedded in modern Japanese make sense only because USA has won the War (which is a good thing otherwise, but some of its effects on Japanese are less desirable). Besides this historical moti

Japanese could be written with the Latin alphabet very well, if a set of kanji radicals were retained and inserted before a part of the words, to disambiguate their meaning. This is a not a new method of writing, but this is how writing was

Using doubled vowels instead of diacritics is just one more concession to Americans, who are unfamiliar with the use of diacritics and whose software frequently does not work correctly when text contains characters with diacritics. Hepburn

When I was young, in Europe, there was some ointment made of cod liver oil and zinc oxide, which was extremely effective for the quick healing of non-infected wounds or burns. For some reason nowadays, that ointment does not exist any more.

The cost is an extremely nonlinear function of the speed expressed in tokens per second. Throughputs of around 1 token per second can be achieved even for the biggest currently existing open-weights models with a mini-PC with 2 internal M.2

Saying that an application uses io_uring for input/output provides almost zero information. It provides about the same information as saying that an application is run on Linux. io_uring is an alternative method of invocation for a ver

No, though even a hash like xxh3 can be useful when speed is more important than collision resistance. There are many hashes that use more thorough mixing functions than can be achieved with one or a few arithmetic operations (like in unive

There are many kinds of universal hashing, many of which are not based on polynomial evaluation. However, the most common kinds of universal hashing, i.e. those which are used for computing message authentication codes (MAC) in the TLS and

Looking now at that, it does a poor job of making a true refutation. What that article explains, is that the system of credit card fees and rewards that is used in USA is extraordinarily complicated, variable and obfuscated in comparison wi

In modern computers, the throughput of an execution unit is the same for multiplications and additions, but multiplication frequently has a greater latency, by 1 or 2 clock cycles. Many CPUs, like the AMD Zen CPUs, have more execution units

It is applicable, but it is not useful. Universal hashes use the input text as the set of coefficients. This method requires additional preprocessing of the coefficients, before starting to evaluate the polynomial. That preprocessing would

"Synthetic cell factory" seems a hyperbole, because what they make are not living cells, so there is no danger of their proliferation. What they make performs a small part of the functions of a living cell, i.e. they make assembla

This seems to be an acceptable solution. This would not work with HDDs, because the time to seek between 2 partitions of the same device would cause abysmal performance, but on SSDs this should work fine, even if some SSD controllers might

No matter how many external drives you gather, the data coming from them must be squeezed through the peripheral interfaces of the Apple SoC. So your CPU, made by Apple, Intel, AMD etc., has a number of PCIe lanes and a number of USB/T

When you have heterogeneous SSDs, e.g. you mix PCIe 5.0, PCIe 4.0 and Thunderbolt interfaces, you can obtain a greater throughput by managing in software the distribution of data, than by using RAID0. RAID0 works fine only when all the inte

Most desktops and mini-PCs can read simultaneously from only 2 internal M.2 SSDs, 1 of which is PCIe 5.0 and the other is PCIe 4.0. They may have more M.2 sockets but usually except for the first all the others share the same PCIe 4.0 path.

Yes, you are right, once the VRM is erased it is gone for good. Though it is possible to test only a fragment of an object, but I do not know if the instruments that were used were sensitive enough to work with only a very small chip, which
