Interestingly, the term һexa-decimal (hexadecimal) was introduced by IBM in 1963 and is a combination of the Greek word hexi (six) and the Latin decem (ten).
It would be more correct to use the Latin word sexa (six), but the term "sexadecimal" would be perceived somewhat ambiguously.

--
Интересно, что термин һexa- decimal (шестнадцатеричный) введен научный обиход B корпорацией IBM в 1963 году и является комбинацией греческого слова hexi (шесть) и латинского decem (десять). Правильнее было бы использовать латинское же слово sexa (шесть), но термин sexadecimal воспринимался бы несколько неоднозначно

P.S.: from the book

The term “bug” predates the invention of the computer. Thomas Edison called the “little faults and difficulties” with his
inventions “bugs” in 1878.

The first real computer bug was a moth, which got caught between the relays of the Harvard Mark II electromechanical computer in 1947. It was found by Grace Hopper, who logged the incident, along with the moth itself and the comment “first actual case of bug being found.”

Термин «баг» существовал еще до изобретения компьютера. В 1878 году Томас Эдисон называл багами «огрехи и затруднения» в своих изобретениях.

Первый настоящий компьютерный баг был молью, попавшей между контактами реле электромеханического компьютера Harvard Mark II в 1947 году. Ее нашла Грейс Хоппер, которая зарегистрировала этот случай в рабочем журнале, приклеив моль и про-
комментировав: «впервые обнаружен настоящий баг».

J. Robert Oppenheimer - Speech at the Princeton Theological Seminary (1958)

"As really great discoveries are made in science, they may or they may not affect the way people think about the problems of their own lives about what is in vulgar sense called their 'philosophy'"

Magnets used in quantum computers need ultra-low temperatures to operate. A new discovery could radically change that.

An EEVDF CPU scheduler for Linux

https://lwn.net/Articles/925371/

EEVDF replaced, in v6.6 update, Linux kernel scheduler CFS, which had been since v2.6.23.

AFAIU, it computes the process taken "fair" time by new metric "lag" that's calculated with factors like process priority, "virtual deadline" with process allocated time consideration.

Interesting, how much "old" stuff can be optimized with other algorithms' alternatives?
EEVDF algo was est. in 1995

The kernel's completely fair scheduler
(CFS) has the job of managing the allocation of CPU time for most of
the processes running on most Linux systems. CFS was merged for the 2.6.23
release in 2007 and has, with numerous ongoing tweaks, handled the job…
