The Buteyko method or Buteyko breathing technique is a practice used to help regulate breathing, primarily as a treatment for asthma and other respiratory conditions.

Buteyko asserts that numerous medical conditions, including asthma, are caused or exacerbated by chronically increased respiratory rate or hyperventilation. The method aims to correct hyperventilation and encourage shallower, slower breathing. Treatments include a series of reduced-breathing exercises that focus on nasal-breathing, breath-holding and relaxation.

Advocates of the Buteyko method claim that it can alleviate symptoms and reliance on medication for patients with asthma, chronic obstructive pulmonary disease (COPD), and chronic hyperventilation. The medical community questions these claims, given limited and inadequate evidence supporting the theory and efficacy of the method.

In February 2024, a malicious backdoor was introduced to the Linux build of the xz utility within the liblzma library in versions 5.6.0 and 5.6.1 by an account using the name "Jia Tan". The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution through OpenSSH (a suite of secure networking utilities) on the affected Linux system. The issue has been given the Common Vulnerabilities and Exposures number CVE-2024-3094 and has been assigned a CVSS score of 10.0, the highest possible score.

While xz is commonly present in most Linux distributions, at the time of discovery the backdoored version had not yet been widely deployed to production systems, but was present in development versions of major distributions. The backdoor was discovered by the software developer Andres Freund, who announced his findings on 29 March 2024.

Freedom fries was a politically motivated renaming of french fries in the United States. The term was coined in February 2003 in a North Carolina restaurant, and was widely publicized a month later when the then Republican Chairman of the Committee on House Administration, Bob Ney, renamed the menu item in three Congressional cafeterias. The political renaming occurred in context of France's opposition to the proposed invasion of Iraq. Although some restaurants around the nation adopted the renaming, the term became unpopular, in part due to decreasing popularity of the Iraq War. After Ney's resignation as Chairman in 2006, the change of name in Congressional cafeterias was reverted.

🔗 Poetry

The Star Gauge (Chinese: 璇璣圖; pinyin: Xuánjī Tú), or translated as "the armillary sphere chart", is the posthumous title given to a 4th-century Classical Chinese poem written by the Former Qin poet Su Hui for her husband during the Sixteen Kingdoms period. It consists of a 29 by 29 grid of characters, forming a reversible poem that can be read in different ways to form roughly 3,000 smaller rhyming poems. The outer border forms a single circular poem, thought to be both the first and the longest of its kind.

Accumulation by dispossession is a concept presented by the Marxist geographer David Harvey. It defines neoliberal capitalist policies that result in a centralization of wealth and power in the hands of a few by dispossessing the public and private entities of their wealth or land. Such policies are visible in many western nations from the 1970s and to the present day. Harvey argues these policies are guided mainly by four practices: privatization, financialization, management and manipulation of crises, and state redistributions.

🔗 Economics

In economics, the Baumol effect, also known as Baumol's cost disease, is the rise of wages in jobs that have experienced little or no increase in labor productivity, in response to rising salaries in other jobs that have experienced higher productivity growth. The phenomenon was described by William J. Baumol and William G. Bowen in the 1960s and is an example of cross elasticity of demand.

The rise of wages in jobs without productivity gains derives from the requirement to compete for workers with jobs that have experienced productivity gains and so can naturally pay higher salaries, just as classical economics predicts. For instance, if the retail sector pays its managers low wages, they may decide to quit and get jobs in the automobile sector, where wages are higher because of higher labor productivity. Thus, retail managers' salaries increase not due to labor productivity increases in the retail sector, but due to productivity and corresponding wage increases in other industries.

Mark V. Shaney is a synthetic Usenet user whose postings in the net.singles newsgroups were generated by Markov chain techniques, based on text from other postings. The username is a play on the words "Markov chain". Many readers were fooled into thinking that the quirky, sometimes uncannily topical posts were written by a real person.

The system was designed by Rob Pike with coding by Bruce Ellis. Don P. Mitchell wrote the Markov chain code, initially demonstrating it to Pike and Ellis using the Tao Te Ching as a basis. They chose to apply it to the net.singles netnews group.

In the 2010s, personal data belonging to millions of Facebook users was collected by British consulting firm Cambridge Analytica for political advertising without informed consent.

The data was collected through an app called "This Is Your Digital Life", developed by data scientist Aleksandr Kogan and his company Global Science Research in 2013. The app consisted of a series of questions to build psychological profiles on users, and collected the personal data of the users' Facebook friends via Facebook's Open Graph platform. The app harvested the data of up to 87 million Facebook profiles. Cambridge Analytica used the data to analytically assist the 2016 presidential campaigns of Ted Cruz and Donald Trump. Cambridge Analytica was also widely accused of interfering with the Brexit referendum, although the official investigation recognised that the company was not involved "beyond some initial enquiries" and that "no significant breaches" took place.

In interviews with The Guardian and The New York Times, information about the data misuse was disclosed in March 2018 by Christopher Wylie, a former Cambridge Analytica employee. In response, Facebook apologized for their role in the data harvesting and their CEO Mark Zuckerberg testified in April 2018 in front of Congress. In July 2019, it was announced that Facebook was to be fined $5 billion by the Federal Trade Commission due to its privacy violations. In October 2019, Facebook agreed to pay a £500,000 fine to the UK Information Commissioner's Office for exposing the data of its users to a "serious risk of harm". In May 2018, Cambridge Analytica filed for Chapter 7 bankruptcy.

Other advertising agencies have been implementing various forms of psychological targeting for years and Facebook had patented a similar technology in 2012. Nevertheless, Cambridge Analytica's methods and their high-profile clients—including the Trump presidential campaign and the UK's Leave.EU campaign—brought the problems of psychological targeting that scholars have been warning against to public awareness. The scandal sparked an increased public interest in privacy and social media's influence on politics. The online movement #DeleteFacebook trended on Twitter.

🔗 Palaeontology

The cat gap is a period in the fossil record of approximately 25 to 18.5 million years ago in which there are few fossils of cats or cat-like species found in North America. The cause of the "cat gap" is disputed, but may have been caused by changes in the climate (global cooling), changes in the habitat and environmental ecosystem, the increasingly hypercarnivorous trend of the cats (especially the nimravids), volcanic activity, evolutionary changes in dental morphology of the Canidae species present in North America, or a periodicity of extinctions called van der Hammen cycles.
