π Shavian alphabet
The Shavian alphabet (also known as the Shaw alphabet) is an alphabet conceived as a way to provide simple, phonetic orthography for the English language to replace the difficulties of conventional spelling. It was posthumously funded by and named after Irish playwright Bernard Shaw. Shaw set three main criteria for the new alphabet: it should be (1) at least 40 letters; (2) as "phonetic" as possible (that is, letters should have a 1:1 correspondence to phonemes); and (3) distinct from the Latin alphabet to avoid the impression that the new spellings were simply "misspellings".

π The Morris Worm was released 35 years ago today
The Morris worm or Internet worm of November 2, 1988, is one of the oldest computer worms distributed via the Internet, and the first to gain significant mainstream media attention. It resulted in the first felony conviction in the US under the 1986 Computer Fraud and Abuse Act. It was written by a graduate student at Cornell University, Robert Tappan Morris, and launched on 8:30 pm November 2, 1988, from the Massachusetts Institute of Technology network.
Clifford Stoll of Harvard wrote that "Rumors have it that [Morris] worked with a friend or two at Harvard's computing department (Harvard student Paul Graham sent him mail asking for 'Any news on the brilliant project')."

π Truchet Tiles
In information visualization and graphic design, Truchet tiles are square tiles decorated with patterns that are not rotationally symmetric. When placed in a square tiling of the plane, they can form varied patterns, and the orientation of each tile can be used to visualize information associated with the tile's position within the tiling.
Truchet tiles were first described in a 1704 memoir by SΓ©bastien Truchet entitled "MΓ©moire sur les combinaisons", and were popularized in 1987 by Cyril Stanley Smith.

π Presidential Immunity in the United States
Presidential immunity is the concept that sitting presidents of the United States have civil or criminal immunity for their official acts. Neither civil nor criminal immunity is explicitly granted in the Constitution or any federal statute. However, the Supreme Court of the United States ruled in Trump v. United States (2024) that all presidents have absolute criminal immunity for official acts under core constitutional powers, presumptive immunity for other official acts. The court held that there is no immunity for unofficial acts. The court made this decision after former President Trump claimed immunity from prosecution for actions performed within the perimeter of his responsibilities as president.
Previously, the Supreme Court had found in Nixon v. Fitzgerald (1982) that the president has absolute immunity from civil damages actions regarding conduct within the "outer perimeter" of their duties. However, in Clinton v. Jones (1997), the court ruled against temporary immunity for sitting presidents from suits arising from pre-presidency conduct. Some scholars suggested an immunity from arrest and criminal prosecution as well, a view which became the practice of the Department of Justice under a pair of memoranda (1973 and 2000) from the Office of Legal Counsel. Presidents Richard Nixon, Bill Clinton, and Donald Trump were criminally investigated while in office, but none were prosecuted while still in office.

π Kevinism
In German, Kevinismus ("Kevinism") is the negative preconception German people have of Germans with trendy, exotic-sounding first names considered to be an indicator of a low social class.
