A pangram or holoalphabetic sentence is a sentence using every letter of a given alphabet at least once. Pangrams have been used to display typefaces, test equipment, and develop skills in handwriting, calligraphy, and keyboarding.

🔗 Philosophy 🔗 Philosophy/Logic

Trivialism (from Latin trivialis 'found everywhere') is the logical theory that all statements (also known as propositions) are true and that all contradictions of the form "p and not p" (e.g. the ball is red and not red) are true. In accordance with this, a trivialist is a person who believes everything is true.

In classical logic, trivialism is in direct violation of Aristotle's law of noncontradiction. In philosophy, trivialism is considered by some to be the complete opposite of skepticism. Paraconsistent logics may use "the law of non-triviality" to abstain from trivialism in logical practices that involve true contradictions.

Theoretical arguments and anecdotes have been offered for trivialism to contrast it with theories such as modal realism, dialetheism and paraconsistent logics.

🔗 New York City 🔗 Architecture 🔗 Skyscrapers 🔗 Telecommunications

33 Thomas Street (formerly the AT&T Long Lines Building) is a 550-foot-tall (170 m) skyscraper in Civic Center, Lower Manhattan, New York City. It stands on the east side of Church Street, between Thomas Street and Worth Street. The building is an example of the Brutalist architectural style. It is a telephone exchange or wire center building which contained three major 4ESS switches used for interexchange (long distance) telephony, as well as a number of other switches used for competitive local exchange carrier services. However, it is not used for incumbent local exchange carrier services, and is not a central office. The CLLI code for this facility is NYCMNYBW. The building has also been described as the likely location of a National Security Agency (NSA) mass surveillance hub codenamed TITANPOINTE.

Chiastic structure, or chiastic pattern, is a literary technique in narrative motifs and other textual passages. An example of chiastic structure would be two ideas, A and B, together with variants A' and B', being presented as A,B,B',A'. Chiastic structures that involve more components are sometimes called "ring structures", "ring compositions", or, in cases of very ambitious chiasmus, "onion-ring compositions". These may be regarded as chiasmus scaled up from words and clauses to larger segments of text.

These often symmetrical patterns are commonly found in ancient literature such as the epic poetry of the Iliad and the Odyssey. Classicist Bruno Gentili describes this technique as "the cyclical, circular, or 'ring' pattern (ring composition). Here the idea that introduced a compositional section is repeated at its conclusion, so that the whole passage is framed by material of identical content". Meanwhile, in classical prose, scholars often find chiastic narrative techniques in the Histories of Herodotus:

"Herodotus frequently uses ring composition or 'epic regression' as a way of supplying background information for something discussed in the narrative. First an event is mentioned briefly, then its precedents are reviewed in reverse chronological order as far back as necessary; at that point the narrative reverses itself and moves forward in chronological order until the event in the main narrative line is reached again."

Various chiastic structures are also seen in the Hebrew Bible, the New Testament, the Book of Mormon, and the Quran.

🔗 Pharmacology

Human anti-mouse antibody or human anti-murine antibody (HAMA) is an antibody found in humans which reacts to immunoglobins found in mice.

🔗 Books 🔗 Typography

The printer’s key, also known as the number line, is a line of text printed on the copyright page (often the verso of the title page, especially in English-language publishing) of books, used to indicate the print run. Publishers began this convention about the middle of the 20th century.

An example follows:

This is how the printer's key will appear in the first print run of a book. Numbers are removed with subsequent printings, so if "1" is seen then the book is the first printing of that edition. If it is the second printing then the "1" is removed, meaning that the lowest number seen will be "2".

🔗 Cryptography 🔗 Cryptography/Computer science

A physical unclonable function (sometimes also called physically unclonable function, which refers to a weaker security metric), or PUF, is a physical object that for a given input and conditions (challenge), provides a physically-defined "digital fingerprint" output (response) that serves as a unique identifier, most often for a semiconductor device such as a microprocessor. PUFs are most often based on unique physical variations which occur naturally during semiconductor manufacturing. A PUF is a physical entity embodied in a physical structure. Today, PUFs are usually implemented in integrated circuits and are typically used in applications with high security requirements, more specifically cryptography.

🔗 Video games

In video games, grinding is performing repetitive tasks, usually for a gameplay advantage or loot but in some cases for purely aesthetic or cosmetic benefits. Many video games use different tactics to implement, or reduce, the amount of grinding in the gameplay. The general use of grinding is for "experience points", or to improve a character's level. In addition, the behavior is sometimes referred to as pushing the bar (leveling up), farming (acquiring loot repeatedly from one source), or catassing.

🔗 Typography 🔗 Industrial design

The IBM Selectric typewriter was a highly successful line of electric typewriters introduced by IBM on 31 July 1961.

Instead of the "basket" of individual typebars that swung up to strike the ribbon and page in a typical typewriter of the period, the Selectric had an "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and pivoted to the correct position before striking. The element could be easily changed so as to use different fonts in the same document typed on the same typewriter, resurrecting a capability that had been pioneered by typewriters such as the Hammond and Blickensderfer in the late 19th century. The Selectric also replaced the traditional typewriter's horizontally moving carriage with a roller (platen) that turned to advance the paper but did not move horizontally, while the typeball and ribbon mechanism did.

The Selectric mechanism was notable for using internal mechanical binary coding and two mechanical digital-to-analog converters, called whiffletree linkages, to select the character to be typed.

Selectrics and their descendants eventually captured 75 percent of the United States market for electric typewriters used in business. IBM replaced the Selectric line with the IBM Wheelwriter in 1984 and transferred its typewriter business to the newly formed Lexmark in 1991. By its 25th anniversary, in 1986, a total of more than 13 million machines were made and sold.
