The AlphaSmart was a brand of portable, battery powered, word-processing keyboards manufactured by NEO Direct, Inc. (formerly Renaissance Learning, Inc, formerly AlphaSmart, Inc., formerly Intelligent Peripheral Devices, Inc.). Originally released in 1993, the first AlphaSmart models were intended for writing on-the-go and could be plugged into a computer to transfer saved written text. The units' portability and long battery life made them valuable to journalists, writers, and students. Later models expanded functionality by spell-checking, running applications, and accessing wireless printers.

The last model, Neo 2, was released in 2007, and production was discontinued by the company in late September 2013, although the company still offers support and software to existing users.

The Airbus A300-600ST (Super Transporter), or Beluga, is a version of the standard A300-600 wide-body airliner modified to carry aircraft parts and outsize cargo. It received the official name of Super Transporter early on; however, the name Beluga, a whale it resembles, gained popularity and has since been officially adopted. The Beluga XL, based on the Airbus A330 with similar modifications and dimensions, was developed by Airbus to replace the type in January 2020.

The IBM 7950, also known as Harvest, was a one-of-a-kind adjunct to the Stretch computer which was installed at the United States National Security Agency (NSA). Built by IBM, it was delivered in 1962 and operated until 1976, when it was decommissioned. Harvest was designed to be used for cryptanalysis.

Ruby is an interpreted, high-level, general-purpose programming language which supports multiple programming paradigms. It was designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. It was developed in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan.

Ruby is dynamically typed and uses garbage collection and just-in-time compilation. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. According to the creator, Ruby was influenced by Perl, Smalltalk, Eiffel, Ada, BASIC, Java and Lisp.

🔗 Mathematics

Connes' embedding problem, formulated by Alain Connes in the 1970s, is a major problem in von Neumann algebra theory. During that time, the problem was reformulated in several different areas of mathematics. Dan Voiculescu developing his free entropy theory found that Connes' embedding problem is related to the existence of microstates. Some results of von Neumann algebra theory can be obtained assuming positive solution to the problem. The problem is connected to some basic questions in quantum theory, which led to the realization that it also has important implications in computer science.

The problem admits a number of equivalent formulations. Notably, it is equivalent to the following long standing problems:

• Kirchberg's QWEP conjecture in C*-algebra theory
• Tsirelson's problem in quantum information theory
• The predual of any (separable) von Neumann algebra is finitely representable in the trace class.

In January 2020, Ji, Natarajan, Vidick, Wright, and Yuen announced a result in quantum complexity theory that implies a negative answer to Connes' embedding problem. However, an error was discovered in September 2020 in an earlier result they used; a new proof avoiding the earlier result was published as a preprint in September. A broad outline was published in Communications of the ACM in November 2021, and an article explaining the connection between MIP*=RE and the Connes Embedding Problem appeared in October 2022.

Colorless green ideas sleep furiously is a sentence composed by Noam Chomsky in his 1957 book Syntactic Structures as an example of a sentence that is grammatically correct, but semantically nonsensical. The sentence was originally used in his 1955 thesis The Logical Structure of Linguistic Theory and in his 1956 paper "Three Models for the Description of Language". Although the sentence is grammatically correct, no obvious understandable meaning can be derived from it, and thus it demonstrates the distinction between syntax and semantics. As an example of a category mistake, it was used to show the inadequacy of certain probabilistic models of grammar, and the need for more structured models.

Since 2025, the second Donald Trump administration of the United States has sought to annex Greenland, an autonomous territory of Denmark (itself in the European Union), triggering an ongoing international diplomatic crisis. This escalated in early 2026 after Trump refused to rule out the use of military force to annex Greenland and threatened a 25% import tax on European Union (EU) goods unless Denmark ceded Greenland. Trump's statements sparked a confrontation with Denmark and the EU (supported by several other NATO members), reigniting earlier concerns of a US–EU trade war. On 21 January, Trump reversed his position at the 2026 Davos conference, pledging not to use force or tariffs to annex Greenland.

Trump had unsuccessfully tried to purchase Greenland during his first presidency. After his 2024 re-election, in January 2026, he said "it may be a choice" whether to preserve NATO or seize Greenland and that he "no longer [felt] an obligation to think purely of Peace" after not receiving the Nobel Peace Prize. A report by the Danish Defence Intelligence Service mentioned the United States (US) as a potential threat to national security for the first time in its history, and Danish officials raised concerns about reports that Director of National Intelligence Tulsi Gabbard had assigned agents to spy on Greenland.

The Greenlandic and Danish prime ministers rejected any US takeover, saying they would defend Greenland in the event of an attack. Both NATO and EU members would be obliged to assist Denmark in the event of an attack. Denmark and eight NATO allies deployed forces to defend the territory. In response, Trump threatened a trade war against the EU, leading European politicians to suspend a proposed EU–US trade agreement and consider placing sanctions on the US.

Trump's threats led to large-scale protests in both Greenland and Denmark. A YouGov poll found only 8% of Americans supported an invasion of Greenland, with 73% opposed. Trump's actions faced heavy opposition in Congress from both major parties, with Republican speaker of the House Mike Johnson describing Trump's threats as "completely inappropriate" and a bipartisan congressional delegation traveling to Copenhagen to support Denmark–US relations. The crisis was described as one of the most erratic episodes involving a US president, prompting scrutiny of Trump's age and fitness for office.

On 21 January, Trump reversed course, first ruling out military force and then abandoning tariff threats after talks with NATO secretary-general Mark Rutte reached what Trump called a "framework of a future deal". Greenland and Denmark ruled out any deal altering the sovereignty of Greenland and Denmark, with Trump's comments referring to pre-existing commitments from a 1951 US–Denmark treaty.

Gödel's Loophole is a "inner contradiction" in the Constitution of the United States which Austrian-German-American logician, mathematician, and analytic philosopher Kurt Gödel claimed to have discovered in 1947. The flaw would have allowed the American democracy to be legally turned into a dictatorship. Gödel told his friend Oskar Morgenstern about the existence of the flaw and Morgenstern told Albert Einstein about it at the time, but Morgenstern, in his recollection of the incident in 1971, never mentioned the exact problem as Gödel saw it. This has led to speculation about the precise nature of what has come to be called "Gödel's Loophole". It has been called "one of the great unsolved problems of constitutional law."
