The only advantage of the hyperbolic logarithm (a.k.a. natural logarithm) is that the multiplicative factor is unity when computing its derivative or primitive. The binary logarithm can be computed faster and more accurately, except for arg

Mechanisms equivalent with the overlapped I/O of Windows NT (1993) already existed 30 years earlier, e.g. in IBM OS/360 and PL/I (1964/1965). The main features that were better in Windows NT than in the UNIX-derived oper

Allready in 1983, 4.2BSD had 3 different attempts at doing multiplexed/asynchronous I/O: Non-blocking I/O: "O_NONBLOCK" with "EWOULDBLOCK" (or "EAGAIN") Signal-driven I/O: "O_ASYNC&quot

Chosen plaintext attacks can work against things like hashing algorithms. But with methods of encryption like AES GCM or any other based on the counter mode, an encrypting oracle does not encrypt the text provided by the adversary. It encry

China has already produced a supercomputer that has beaten all US supercomputers, which was made public a month ago, and now it occupies the first place in Top 500. Not only it has the greatest absolute performance, but it also reaches a mu

The great mistake is that those servers have a management Ethernet interface connected to the Internet. The management Ethernet port of a server, on which it listens for the IPMI protocol, is supposed to be connected only to a dedicated int

They were not hypothesized. The term "Sea People" or "People of the Sea" has been taken from Egyptian documents that described a series of battles for defending Egypt against them. Egypt succeeded to repel them, but othe

Yes, while I agree with most of the criticism about the movie, that sentence has also stricken me as incorrect. It is not known who the "sea people" were, e.g. whether they were invaders coming from far away or they were just some

As someone who has read the Odyssey in original, and who has enjoyed it very much, the useful information that I got from this review is that most of what I considered as the best parts of Odyssey are exactly those which are missing from th

My test ranked first Daniel Mendelsohn and second Emily Wilson. I was aware of Wilson's translation, but not of that of Mendelsohn. This has made me curious to read Mendelsohn's translation, but in general I do not like to read tr

It should be noted that the attack is not only an attack against a weakened AES, but it is also a chosen-plaintext attack. It is standard in cryptography to analyze ciphers under this kind of attack, which is stronger than normal attacks, b

Their production capacity is constrained, but not so constrained as to prevent them to demonstrate a supercomputer faster than any US supercomputer, made with custom CPUs designed and fabricated in China. The limited production capacity mea

Unfortunately "incredibly behind" can be said about most countries of the world, many of which had electronics industries that have been destroyed during the nineties of the last century, but not about China. China is already able

As it is said in TFA, it did not have the structure of a computer, but it was a very complex digital automaton and it contained the typical digital circuits that are used today, like counters and shift registers, which at that time were a n

From your link, the bees are nested within Crabronidae, most of which are predatory wasps, e.g. the beewolves. So there is no doubt that the immediate ancestors of bees were predatory, like also their more distant ancestors that they share

Regarding autocomplete, while I have first used autocomplete only in 1990 (in the text editor BRIEF), autocomplete had already existed in 1972, in the command line interpreter of the operating system TENEX for DEC PDP-10 (i.e. the equivalen

Restricting the word "insects" to hexapods is a modern convention that does not have any basis in etymology. Aristotle used the word "insects" for all terrestrial arthropods and this was followed for millennia until the

The early Hymenoptera were predatory, like wasps still are. Bees, which feed on pollen and nectar from plant flowers, instead of catching other insects, have evolved much later from wasp-like Hymenoptera, after angiosperms were already wide

Professionals have instruments that measure the precise period of the clock ticks that are heard, so the adjustment lever can be set accurately immediately. With a computer (or with a smartphone), one could easily improvise an equivalent in

Indeed, while the SVE support is reasonably widespread because it is included in all the higher-priced Android smartphones launched during the last 4 years and a half, some very cheap smartphones with Cortex-A78, without SVE support, are st

I agree that a language should also provide integers of unlimited size (possibly also non-negative integers of unlimited size) like many LISP variants, Python etc. Integer range types, like in Pascal and Ada, should also be available. Such

I found the support of the idea that for integers the overflows should be handled by "wrapping" as exceedingly dumb. Those where overflow results in wrapping are not integers and any such wrapping is an error that is difficult to

Dip pens do not require more pressure than fountain pens. However, most nibs for dip pens cause more friction on the paper, because they do not have the balls that are typically welded on the ends of the nibs for fountain pens, so writing w

Looking now at the corresponding Wikipedia page, I see that actually there have already been created a few clones, both for Windows and for Linux. I have not used BRIEF for Windows, so I do not know if it was as good as BRIEF for MS-DOS. Un

Out-of-the-box, BRIEF was not especially impressive. Its strength was its embedded scripting language, which may have been inspired by Emacs LISP. With the scripting language, you could change everything, including the behavior of any key p
