Piyamaradu (also spelled Piyama-Radu, Piyama Radu, Piyamaradus, Piyamaraduš) was a warlike personage whose name figures prominently in the Hittite archives of the middle and late 13th century BC in western Anatolia. His history is of particular interest because it appears to intertwine with that of the Trojan War. Some scholars assume that his name is cognate to that of King Priam of Troy.

Toilet paper when used with a toilet roll holder with a horizontal axle parallel to both the wall and the floor has two possible orientations: the toilet paper may hang over (in front of) or under (behind) the roll.

Some people hold strong opinions on the matter; advice columnist Ann Landers said that the subject was the most responded to (15,000 letters in 1986) and controversial issue in her column's history. Defenders of either position cite advantages ranging from aesthetics, hospitality, and cleanliness to paper conservation, ease of detaching sheets, and compatibility with pets. Some writers have proposed connections to age, sex, or political philosophy, and survey evidence has shown a correlation with socioeconomic status.

Solutions where the views of household members differ include using separate dispensers or separate bathrooms and ignoring the issue. One man advocates a plan under which his country will standardize on a single forced orientation, and at least one inventor hopes to popularize a new kind of toilet roll holder which swivels from one orientation to the other.

🔗 Novels

I, Libertine is a literary hoax novel that began as a practical joke by late-night radio raconteur Jean Shepherd who aimed to lampoon the process of determining best-selling books. After generating substantial attention for a novel that didn't actually exist, Shepherd approved a 1956 edition of the book written mainly by Theodore Sturgeon — which became an actual best-seller, with all profits donated to charity.

The hypothesis of linguistic relativity, part of relativism, also known as the Sapir–Whorf hypothesis , or Whorfianism is a principle claiming that the structure of a language affects its speakers' world view or cognition, and thus people's perceptions are relative to their spoken language.

The principle is often defined in one of two versions: the strong hypothesis, which was held by some of the early linguists before World War II, and the weak hypothesis, mostly held by some of the modern linguists.

• The strong version says that language determines thought and that linguistic categories limit and determine cognitive categories.
• The weak version says that linguistic categories and usage only influence thought and decisions.

The principle had been accepted and then abandoned by linguists during the early 20th century following the changing perceptions of social acceptance for the other especially after World War II. The origin of formulated arguments against the acceptance of linguistic relativity are attributed to Noam Chomsky.

The Hardest Logic Puzzle Ever is a logic puzzle so called by American philosopher and logician George Boolos and published in The Harvard Review of Philosophy in 1996. Boolos' article includes multiple ways of solving the problem. A translation in Italian was published earlier in the newspaper La Repubblica, under the title L'indovinello più difficile del mondo.

It is stated as follows:

Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for yes and no are da and ja, in some order. You do not know which word means which.

Boolos provides the following clarifications: a single god may be asked more than one question, questions are permitted to depend on the answers to earlier questions, and the nature of Random's response should be thought of as depending on the flip of a fair coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely.

Michael J. (Mike) Karels (August 2, 1956 – June 2, 2024) was an American software engineer and one of the key figures in history of BSD UNIX.

In 1993, the USENIX Association gave a Lifetime Achievement Award (Flame) to the Computer Systems Research Group at University of California, Berkeley, honoring 180 individuals, including Karels, who contributed to the CSRG's 4.4BSD-Lite release.

In February 1992 Karels moved to BSDi (Berkeley Software Design) and designed BSD/OS, which, for years, was the only commercially available BSD style Unix on Intel platform. BSDi's software assets were bought by Wind River in April 2001, and Karels joined Wind River as the Principal Technologist for the BSD/OS platform.

Following his time at Wind River, Karels joined Secure Computing Corporation in 2003 as a Sr. Principal Engineer. Secure Computing used BSD/OS as the basis for SecureOS, the operating system of its Sidewinder firewall, later known as McAfee Firewall Enterprise. However, BSD/OS development had ceased, so Karels was involved in transitioning SecureOS to use FreeBSD as its base, and porting its unique features over to the new kernel. Secure Computing and the Sidewinder firewall team went through a series of acquisitions and spinoffs, including McAfee, Intel, and Forcepoint, so while Karels appeared to have several different jobs from that point onward, he had remained in roughly the same role from 2003 until his retirement in 2021.

The Sidewinder product was eventually discontinued, though Karels fed some SecureOS changes back into the main FreeBSD codebase. Karels officially became a FreeBSD committer in 2017. He continued working on FreeBSD in his spare time following retirement.
