🔗 Apple Inc. 🔗 Software 🔗 Software/Computing

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.

The Padmanabhaswamy temple treasure is a collection of valuable objects including gold thrones, crowns, coins, statues and ornaments, diamonds and other precious stones. It was discovered in some of the subterranean vaults of the Padmanabhaswamy Temple in Thiruvananthapuram, in the Indian state of Kerala, when five of its six (or possibly eight) vaults were opened on 27 June 2011. The vaults were opened on the orders of the Supreme Court of India, which was hearing a private petition seeking transparency in the running of the temple. The discovery of the treasure attracted widespread national and international media attention as it is considered to be the largest collection of items of gold and precious stones in the recorded history of the world. On the possibility of future appropriation of the wealth, for the need of a new management and proper inventorisation of the articles in the vaults, a public interest petition was registered with Supreme court of India. In 2020, the royal family won the rights to manage the temple, as well all its financial aspects. The Supreme Court of India overruled the Kerala High Court's legal jurisprudence based on regional facts and recognition of the nullified princely agreement based on "Ruler of Travancore."

CleanFlicks was a company founded in Utah in 2000 that rented and sold commercially-released DVDs and VHS tapes from which they had edited content which the company considered inappropriate for children or that viewers might otherwise find offensive. CleanFlicks removed sexual content, profanity, some references to deity, and some violence from movies, either by muting audio or clipping entire portions of the track.

A group of major film productions studios sued CleanFlicks in 2002, arguing that their service constituted copyright infringement. A 2006 court ruling closed the company. On March 13, 2007, CleanFlicks reopened its website with "Movies You Can Trust." While legally enjoined from offering edited movies, an email sent by the company on that date indicated that they had reviewed "tens of thousands" of movies and compiled over 1000 that meet their "family-friendly criteria" for sale and rent. In January 2013, the CleanFlicks.com website was no longer online.

Patentleft (also patent left, copyleft-style patent license or open patent) is the practice of licensing patents (especially biological patents) for royalty-free use, on the condition that adopters license related improvements they develop under the same terms. Copyleft-style licensors seek "continuous growth of a universally accessible technology commons" from which they, and others, will benefit.

Patentleft is analogous to copyleft, a license which allows distribution of a copyrighted work and derived works, but only under the same or equivalent terms.

🔗 Novels 🔗 Children's literature 🔗 Novels/Short story

Winnie-the-Pooh (1926) is the first volume of stories about Winnie-the-Pooh, written by A. A. Milne and illustrated by E. H. Shepard. The book focuses on the adventures of a teddy bear called Winnie-the-Pooh and his friends Piglet, a small toy pig; Eeyore, a toy donkey; Owl, a live owl; and Rabbit, a live rabbit. The characters of Kanga, a toy kangaroo, and her son Roo are introduced later in the book, in the chapter entitled "In Which Kanga and Baby Roo Come to the Forest and Piglet has a Bath". The bouncy toy-tiger character of Tigger is not introduced until the sequel, The House at Pooh Corner.

In 2003, Winnie the Pooh was listed at number 7 on the BBC's survey The Big Read.

🔗 Engineering 🔗 Chicago

During the 1850s and 1860s, engineers carried out a piecemeal raising of the level of central Chicago. Streets, sidewalks, and buildings were physically raised on jackscrews. The work was funded by private property owners and public funds.

An incendiary balloon (or balloon bomb) is a balloon inflated with a lighter than air gas such as hot air, hydrogen, or helium, that has a bomb, incendiary device, or Molotov cocktail attached. The balloon is carried by the prevailing winds to the target area, where it falls or releases its payload.

🔗 Computing

In computer science, a Judy array is a data structure implementing a type of associative array with high performance and low memory usage. Unlike most other key-value stores, Judy arrays use no hashing, leverage compression on their keys (which may be integers or strings), and can efficiently represent sparse data, that is, they may have large ranges of unassigned indices without greatly increasing memory usage or processing time. They are designed to remain efficient even on structures with sizes in the peta-element range, with performance scaling on the order of O(log n). Roughly speaking, Judy arrays are highly optimized 256-ary radix trees.

Judy trees are usually faster than AVL trees, B-trees, hash tables and skip lists because they are highly optimized to maximize usage of the CPU cache. In addition, they require no tree balancing and no hashing algorithm is used.

The Judy array was invented by Douglas Baskins and named after his sister.

Casu martzu (Sardinian pronunciation: [ˈkazu ˈmaɾtsu]; literally 'rotten/putrid cheese'), sometimes spelled casu marzu, and also called casu modde, casu cundídu and casu fràzigu in Sardinian language, is a traditional Sardinian sheep milk cheese that contains live insect larvae (maggots). A variation of the cheese, casgiu merzu, is also produced in some Southern Corsican villages like Sartene.

Derived from pecorino, casu martzu goes beyond typical fermentation to a stage of decomposition, brought about by the digestive action of the larvae of the cheese fly of the Piophilidae family. These larvae are deliberately introduced to the cheese, promoting an advanced level of fermentation and breaking down of the cheese's fats. The texture of the cheese becomes very soft, with some liquid (called làgrima, Sardinian for "teardrop") seeping out. The larvae themselves appear as translucent white worms, roughly 8 mm (0.3 in) long.

🔗 Medicine 🔗 COVID-19 🔗 Medicine/Pulmonology 🔗 Medicine/Cardiology

Extracorporeal membrane oxygenation (ECMO), also known as extracorporeal life support (ECLS), is an extracorporeal technique of providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of gas exchange or perfusion to sustain life. The technology for ECMO is largely derived from cardiopulmonary bypass, which provides shorter-term support with arrested native circulation. The device used is a membrane oxygenator, also known as an artificial lung.

ECMO works by temporarily drawing blood from the body to allow artificial oxygenation of the red blood cells and removal of carbon dioxide. Generally, it is used either post-cardiopulmonary bypass or in late-stage treatment of a person with profound heart and/or lung failure, although it is now seeing use as a treatment for cardiac arrest in certain centers, allowing treatment of the underlying cause of arrest while circulation and oxygenation are supported. ECMO is also used to support patients with the acute viral pneumonia associated with COVID-19 in cases where artificial ventilation alone is not sufficient to sustain blood oxygenation levels.
