ka·ṭa·pa·yā·di (Devanagari: कटपयादि) system (also known as Paralppēru, Malayalam: പരല്‍പ്പേര്) of numerical notation is an ancient Indian alphasyllabic numeral system to depict letters to numerals for easy remembrance of numbers as words or verses. Assigning more than one letter to one numeral and nullifying certain other letters as valueless, this system provides the flexibility in forming meaningful words out of numbers which can be easily remembered.

Refal ("[of] Recursive functions' algorithmic language") "is functional programming language oriented toward symbolic computations", including "string processing, language translation, [and] artificial intelligence". It is one of the oldest members of this family, first conceived of in 1966 as a theoretical tool, with the first implementation appearing in 1968. Refal was intended to combine mathematical simplicity with practicality for writing large and sophisticated programs.

One of the first functional programming languages to do so, and unlike Lisp of its time, Refal is based on pattern matching. Its pattern matching works in conjunction with term rewriting.

The basic data structure of Lisp and Prolog is a linear list built by cons operation in a sequential manner, thus with O(n) access to list's nth element. Refal's lists are built and scanned from both ends, with pattern matching working for nested lists as well as the top-level one. In effect, the basic data structure of Refal is a tree rather than a list. This gives freedom and convenience in creating data structures while using only mathematically simple control mechanisms of pattern matching and substitution.

Refal also includes a feature called the freezer to support efficient partial evaluation.

Refal can be applied to the processing and transformation of tree structures, similarly to XSLT.

🔗 Soviet Union

Homo Sovieticus (Dog Latin for "Soviet Man") is a pejorative for an average conformist person in the Soviet Union and other countries of the Eastern Bloc. The term was popularized by Soviet writer and sociologist Aleksandr Zinovyev, who wrote the book titled Homo Sovieticus.

Michel Heller asserted that the term was coined in the introduction of a 1974 monograph "Sovetskye lyudi" ("Soviet People") to describe the next level of evolution of humanity thanks to the success of Marxist social experiment.

In a book published in 1981, but available in samizdat in the 1970s, Zinovyev also coined an abbreviation homosos (гомосос, literally a homosucker).

The National Raisin Reserve was a raisin reserve of the United States. It was created after World War II by the government in order to control raisin prices. The reserve was run by the Raisin Administrative Committee. It was enforced by means of a "marketing order". In 2015, the United States Supreme Court ruled the reserve unconstitutional and ended it.

🔗 Internet culture 🔗 Cats

Longcat (2002 – 20 September 2020) was a Japanese domestic cat that became the subject of an Internet meme due to her length. Longcat, whose real name was "Shiroi", was born in 2002. An image depicting her being held with "outstretched paws" became popular on Japanese imageboard Futaba Channel, where it was nicknamed "Nobiko" ("Stretch" in Japanese) some time around 2005 or 2006. She was reportedly 65 centimetres (26 in) "from head to toe".

Subsequently, the meme spread to English-language websites, primarily 4chan's /b/, where it was edited into various images, and even had a song written about it. A backstory was invented for the cat, involving a world-ending battle called "Catnarok" with a nemesis named "Tacgnol" (resembling Longcat with the colors inverted).

The virtual community and message board Subeta, which made available a number of pixel art virtual accessories for user avatars, briefly introduced a "Longcat scarf" in 2007; this prompted "a legion of internet users to attack Subeta", primarily in the form of a DDoS campaign involving "all of the chans", until the Longcat item was removed later in the month. A Pokémon design released in 2019, the "Gigantamax Meowth", was compared by some commentators to Longcat.

In a 2019 interview, Longcat's owner said that the cat was "originally rescued after being discovered on the street in 2002", and at the time was thin with gray hair; as she grew older, she became white and fluffy. The cat was deaf. In 2019, Longcat's owner said that, at the age of 17, the cat no longer "climbed to high places" but was "relaxing and living her life".

In September 2020, after a period of ill health, Longcat was taken to the hospital, and died at the age of 18.

SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family of standards, released by NIST on August 5, 2015. Although part of the same series of standards, SHA-3 is internally different from the MD5-like structure of SHA-1 and SHA-2.

SHA-3 is a subset of the broader cryptographic primitive family Keccak (), designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. Keccak's authors have proposed additional uses for the function, not (yet) standardized by NIST, including a stream cipher, an authenticated encryption system, a "tree" hashing scheme for faster hashing on certain architectures, and AEAD ciphers Keyak and Ketje.

Keccak is based on a novel approach called sponge construction. Sponge construction is based on a wide random function or random permutation, and allows inputting ("absorbing" in sponge terminology) any amount of data, and outputting ("squeezing") any amount of data, while acting as a pseudorandom function with regard to all previous inputs. This leads to great flexibility.

NIST does not currently plan to withdraw SHA-2 or remove it from the revised Secure Hash Standard. The purpose of SHA-3 is that it can be directly substituted for SHA-2 in current applications if necessary, and to significantly improve the robustness of NIST's overall hash algorithm toolkit.

The creators of the Keccak algorithms and the SHA-3 functions suggest using the faster function KangarooTwelve with adjusted parameters and a new tree hashing mode without extra overhead for small message sizes.

Project Babylon was a space gun project commissioned by then Iraqi president Saddam Hussein. It involved building a series of "superguns". The design was based on research from the 1960s Project HARP led by the Canadian artillery expert Gerald Bull. There were most likely four different devices in the program.

The project began in 1988; it was halted in 1990 after Bull was assassinated, and parts of the superguns were seized in transit around Europe. The components that remained in Iraq were destroyed by the United Nations after the 1991 Persian Gulf War.

Audie Leon Murphy (20 June 1925 – 28 May 1971) was an American soldier, actor, and songwriter. He was widely celebrated as the most decorated American combat soldier of World War II, and has been described as the most highly decorated soldier in U.S. history. He received every military combat award for valor available from the United States Army, as well as French and Belgian awards for heroism. Murphy received the Medal of Honor for valor that he demonstrated at the age of 19 for single-handedly holding off a company of German soldiers for an hour at the Colmar Pocket in France in January 1945, before leading a successful counterattack while wounded and out of ammunition.

Murphy was born into a large family of sharecroppers in Hunt County, Texas. After his father abandoned them, his mother died when he was a teenager. Murphy left school in fifth grade to pick cotton and find other work to help support his family; his skill with a hunting rifle helped feed his family.

After the attack on Pearl Harbor in 1941, Murphy's older sister helped him to falsify documentation about his birthdate in order to meet the minimum age requirement for enlisting in the military. Turned down initially for being underweight by the Army, Navy, and the Marine Corps, he eventually was able to enlist in the Army. He first saw action in the 1943 Allied invasion of Sicily; then in 1944 he participated in the Battle of Anzio, the liberation of Rome, and the invasion of southern France. Murphy fought at Montélimar and led his men on a successful assault at L'Omet quarry near Cleurie in northeastern France in October. Despite suffering from multiple illnesses and wounds throughout his service, Murphy became one of the most praised and decorated soldiers of World War II. He is credited with killing 241 enemy soldiers.

After the war, Murphy embarked on a 21-year acting career. He played himself in the 1955 autobiographical film To Hell and Back, based on his 1949 memoirs of the same name, but most of his roles were in Westerns. He made guest appearances on celebrity television shows and starred in the series Whispering Smith. Murphy was a fairly accomplished songwriter. He bred quarter horses in California and Arizona, and became a regular participant in horse racing.

Because Murphy had what would today be described as post-traumatic stress disorder (PTSD), then known as "battle fatigue", he slept with a loaded handgun under his pillow. He looked for solace in addictive sleeping pills. In his last few years, he was plagued by money problems but refused offers to appear in alcohol and cigarette commercials because he did not want to set a bad example. Murphy died in a plane crash in Virginia in 1971, shortly before his 46th birthday. He was interred with military honors at Arlington National Cemetery, where his grave is one of the most visited.
