An antimacassar is a small cloth placed over the backs or arms of chairs, or the head or cushions of a sofa, to prevent soiling of the permanent fabric underneath. The name also refers to the cloth flap 'collar' on a sailor's shirt or top, used to keep macassar oil off the uniform.

Macassar oil was an unguent for the hair commonly used by men in the early 19th century, and reputed to have been manufactured from ingredients purchased in the port of Makassar in the Dutch East Indies. The poet Byron called it "thine incomparable oil, Macassar". The fashion for oiled hair became so widespread in the Victorian and the Edwardian period that housewives began to cover the arms and backs of their chairs with washable cloths to prevent the fabric coverings from being soiled. Around 1850, these started to be known as antimacassars. They were also installed in theatres, from 1865.

They came to have elaborate patterns, often in matching sets for the various items of parlour furniture; they were either made at home using a variety of techniques such as crochet or tatting, or purchased. The original antimacassars were usually made of stiff white crochet-work, but in the third quarter of the 19th century they became simpler and softer, usually fabric embroidered with a simple pattern in wool or silk.

By the beginning of the 20th century, antimacassars had become so associated in people's minds with the Victorian period that the word briefly became a figurative term for it. For example, antimacassars are suggestive of old-fashioned, Victorian-era women in Rebecca West's novel The Return of the Soldier.

Antimacassars are also used on the seat headrests of commercial passenger transport vehicles, such as trains, buses and, especially, aircraft, to prevent the transmission of hair dressings and conditions between passengers, simplify maintenance, and extend the life of fabrics.

The dangerous bend or caution symbol ☡ (U+2621 ☡ CAUTION SIGN) was created by the Nicolas Bourbaki group of mathematicians and appears in the margins of mathematics books written by the group. It resembles a road sign that indicates a "dangerous bend" in the road ahead, and is used to mark passages tricky on a first reading or with an especially difficult argument.

Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi network. Inspired by hobo symbols, the warchalking marks were conceived by a group of friends in June 2002 and publicised by Matt Jones who designed the set of icons and produced a downloadable document containing them. Within days of Jones publishing a blog entry about warchalking, articles appeared in dozens of publications and stories appeared on several major television news programs around the world.

The word is formed by analogy to wardriving, the practice of driving around an area in a car to detect open Wi-Fi nodes. That term in turn is based on wardialing, the practice of dialing many phone numbers hoping to find a modem.

Having found a Wi-Fi node, the warchalker draws a special symbol on a nearby object, such as a wall, the pavement, or a lamp post. Those offering Wi-Fi service might also draw such a symbol to advertise the availability of their Wi-Fi location, whether commercial or personal.

🔗 Novels

Lanark, subtitled A Life in Four Books, is the first novel of Scottish writer Alasdair Gray. Written over a period of almost thirty years, it combines realist and dystopian surrealist depictions of his home city of Glasgow.

Its publication in 1981 prompted Anthony Burgess to call Gray "the best Scottish novelist since Walter Scott". Lanark won the inaugural Saltire Society Book of the Year award in 1982, and was also named Scottish Arts Council Book of the Year. The book, still his best known, has since become a cult classic. In 2008, The Guardian heralded Lanark as "one of the landmarks of 20th-century fiction."

A/UX is a Unix-based operating system from Apple Computer for Macintosh computers, integrated with System 7's graphical interface and application compatibility. It is Apple's first official Unix-based operating system, launched in 1988 and discontinued in 1995 with version 3.1.1. A/UX requires select 68k-based Macintosh models with an FPU and a paged memory management unit (PMMU), including the Macintosh II, SE/30, Quadra, and Centris series.

Described by InfoWorld as "an open systems solution with the Macintosh at its heart", A/UX is based on UNIX System V Release 2.2, with features from System V Releases 3 and 4 and BSD versions 4.2 and 4.3. It is POSIX- and System V Interface Definition (SVID)-compliant and includes TCP/IP networking since version 2. Having a Unix-compatible, POSIX-compliant operating system enabled Apple to bid for large contracts to supply computers to U.S. federal government institutes.

🔗 Japan

In Japanese culture, a hatsuyume (Japanese: 初夢) is the first dream one has in the new year. Traditionally, the contents of such a dream would foretell the luck of the dreamer in the ensuing year. In Japan, the night of December 31 was often passed without sleeping, so the hatsuyume is often experienced during the night of January 1; the day after the night of the "first dream" is also known as the hatsuyume. This day is January 2 in the Gregorian calendar, but was different in the traditional Japanese calendar.

It is considered to be particularly good luck to dream of Mount Fuji, a hawk, and an eggplant. This belief has been in place since the early Edo period but there are various theories regarding the origins as to why this particular combination was considered to be auspicious. One theory suggests that this combination is lucky because Mount Fuji is Japan's highest mountain, the hawk is a clever and strong bird, and the word for eggplant (茄子, nasu or nasubi) suggests achieving something great (成す nasu). Another theory suggests that this combination arose because Mount Fuji, falconry, and early eggplants were favorites of the shōgun Tokugawa Ieyasu.

Although this superstition is well known in Japan, often memorized in the form ichi-Fuji, ni-taka, san-nasubi (一富士、二鷹、三茄子; 1. Fuji, 2. Hawk, 3. Eggplant), the continuation of the list is not as well known. The continuation is yon-sen, go-tabako, roku-zatō (四扇、五煙草、六座頭; 4. Fan, 5. Tobacco, 6. Blind acupressurer). The origins of this trio are less well known, and it is unclear whether they were added after the original three or whether the list of six originated at the same time.

Operation Freakout, also known as Operation PC Freakout, was a Church of Scientology covert plan intended to have the U.S. author and journalist Paulette Cooper imprisoned or committed to a psychiatric hospital. The plan, undertaken in 1976 following years of church-initiated lawsuits and covert harassment, was meant to eliminate the perceived threat that Cooper posed to the church and obtain revenge for her publication in 1971 of a highly critical book, The Scandal of Scientology. The Federal Bureau of Investigation discovered documentary evidence of the plot and the preceding campaign of harassment during an investigation into the Church of Scientology in 1977, eventually leading to the church compensating Cooper in an out-of-court settlement.

Clanging (or clang associations) is a symptom of mental disorders, primarily found in patients with schizophrenia and bipolar disorder. This symptom is also referred to as association chaining, and sometimes, glossomania.

Steuber defines it as "repeating chains of words that are associated semantically or phonetically with no relevant context". This may include compulsive rhyming or alliteration without apparent logical connection between words.

Clanging refers specifically to behavior that is situationally inappropriate. While a poet rhyming is not evidence of mental illness, disorganized speech that impedes the patient's ability to communicate is a disorder in itself, often seen in schizophrenia.
