The Scottish Café (Polish: Kawiarnia Szkocka) was a café in Lwów, Poland (now Lviv, Ukraine) where, in the 1930s and 1940s, mathematicians from the Lwów School of Mathematics collaboratively discussed research problems, particularly in functional analysis and topology.

Stanislaw Ulam recounts that the tables of the café had marble tops, so they could write in pencil, directly on the table, during their discussions. To keep the results from being lost, and after becoming annoyed with their writing directly on the table tops, Stefan Banach's wife provided the mathematicians with a large notebook, which was used for writing the problems and answers and eventually became known as the Scottish Book. The book—a collection of solved, unsolved, and even probably unsolvable problems—could be borrowed by any of the guests of the café. Solving any of the problems was rewarded with prizes, with the most difficult and challenging problems having expensive prizes (during the Great Depression and on the eve of World War II), such as a bottle of fine brandy.

For problem 153, which was later recognized as being closely related to Stefan Banach's "basis problem", Stanisław Mazur offered the prize of a live goose. This problem was solved only in 1972 by Per Enflo, who was presented with the live goose in a ceremony that was broadcast throughout Poland.

The café building now houses the Szkocka Restaurant & Bar (named for the original Scottish Café) and the Atlas Deluxe hotel at the street address of 27 Taras Shevchenko Prospekt.

High Efficiency Image File Format (HEIF) is a container format for storing individual digital images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio and video.

HEIF can store images encoded with multiple coding formats, for example both SDR and HDR images. HEVC is an image and video encoding format and the default image codec used with HEIF. HEIF files containing HEVC-encoded images are also known as HEIC files. Such files require less storage space than the equivalent quality JPEG.

HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12).

HEIF was adopted by Apple in 2017 with the introduction of iOS 11.

🔗 Psychology

A cognitive distortion is an exaggerated or irrational thought pattern involved in the onset and perpetuation of psychopathological states, especially those more influenced by psychosocial factors, such as depression and anxiety. Psychiatrist Aaron T. Beck laid the groundwork for the study of these distortions, and his student David D. Burns continued research on the topic. Burns, in The Feeling Good Handbook (1989), described personal and professional anecdotes related to cognitive distortions and their elimination.

Cognitive distortions are thoughts that cause individuals to perceive reality inaccurately. According to the cognitive model of Beck, a negative outlook on reality, sometimes called negative schemas (or schemata), is a factor in symptoms of emotional dysfunction and poorer subjective well-being. Specifically, negative thinking patterns reinforce negative emotions and thoughts. During difficult circumstances, these distorted thoughts can contribute to an overall negative outlook on the world and a depressive or anxious mental state.

Challenging and changing cognitive distortions is a key element of cognitive behavioral therapy (CBT).

Mainline DHT is the name given to the Kademlia-based Distributed Hash Table (DHT) used by BitTorrent clients to find peers via the BitTorrent protocol. The idea of utilizing a DHT for distributed tracking was first implemented in Azureus 2.3.0.0 (now known as Vuze) in May 2005, from which it gained significant popularity. Unrelated but similarly timed BitTorrent, Inc. released their own similar DHT into their client, called Mainline DHT and thus popularized the use of distributed tracking in the BitTorrent Protocol. Measurement shows by 2013 users of Mainline DHT is from 10 million to 25 million, with a daily churn of at least 10 million.

The kóryos (Proto-Indo-European: "army, people under arms" or "detachment, war party") refers to the hypothetical Proto-Indo-European brotherhood of warriors in which unmarried young males served for a number of years before their full integration to the host society, in the context of a rite of passage into manhood.

Subsequent Indo-European traditions and myths feature parallel linkages between property-less adolescent males, perceived as an age-class not yet fully integrated into the community of the married men; their service in a "police-army" sent away for a part of the year in the wild (where they hunted animals and raided foreign communities) and defending the host society during the remaining part of the year; their mystical self-identification with wolves and dogs as symbols of death, promiscuity, lawlessness, and warrior fury; and the idea of a liminality between invulnerability and death on one side, and youth and adulthood on the other side.

The Covox Speech Thing is an external audio device attached to the computer to output digital sound. It was composed of a primitive 8-bit DAC using a resistor ladder and an analogue signal output, and plugged into the printer port of the PC.

The Speech Thing was introduced on December 18, 1987 by Covox, Inc of Eugene, Oregon, for about US$70 (US$79.95 as of 1989), but as its parts were much cheaper than the complete plug, and as its design was fairly simple, people soon started to build their own variants. The plug was used long into the 1990s, as sound cards were still very expensive at that time. The plug was also quite popular in the demoscene.

An inherent problem of the design is that it requires very precise resistors. If normal parts are used, the values get shuffled, especially for quiet sounds, resulting in distortion. Nevertheless, the sound quality of the Covox plug is far superior compared to the PC speaker; even today, a self-built Covox plug is still an inexpensive way to give old computers sound capabilities.

The Bouvier Affair was a number of international lawsuits that started in 2015, and subsequent events. The lawsuits allege that Swiss art shipper and dealer Yves Bouvier defrauded his clients by misrepresenting the original cost of art works and subsequently overcharging them. The affair has played out in courts in Monaco, Switzerland, France, the US, Hong Kong and Singapore.

The alleged victims are "high net worth individuals" in the UK, the US, Asia and Europe, most notably Monaco-based Russian oligarch Dmitry Rybolovlev.

As of February 2018, Bouvier was facing criminal charges in France, Monaco and also in Switzerland after the Geneva Prosecutor opened a new case there.

🔗 Education 🔗 Engineering

Regulation and licensure in engineering is established by various jurisdictions of the world to encourage public welfare, safety, well-being and other interests of the general public and to define the licensure process through which an engineer becomes authorized to practice engineering and/or provide engineering professional services to the public.

As with many other professions, the professional status and the actual practice of professional engineering is legally defined and protected by law in some jurisdictions. Additionally, some jurisdictions permit only licensed engineers (sometimes called registered engineers) to "practice engineering," which requires careful definition in order to resolve potential overlap or ambiguity with respect to certain other professions which may or may not be themselves regulated (e.g. "scientists," or "architects"). Relatedly, jurisdictions that license according to particular engineering discipline need to define those boundaries carefully as well so that practitioners understand what they are permitted to do.

In many cases, only a state or provincial licensed/registered engineer has the authority to take legal responsibility for engineering work or projects (typically via a seal or stamp on the relevant design documentation). Regulations may require that only a licensed or registered engineer can sign, seal or stamp technical documentation such as reports, plans, engineering drawings and calculations for study estimate or valuation or carry out design analysis, repair, servicing, maintenance or supervision of engineering work, process or project. In cases where public safety, property or welfare is concerned, it may be required that an engineer be licensed or registered – though some jurisdictions have an "industrial exemption" that permits engineers to work internally for an organization without licensure so long as they are not making final decisions to release product to the public or offering engineering services directly to the public (e.g. consultant).

Expert witness or opinion in courts or before government committees or commissions can be provided by experts in the respective field, which is sometimes given by a registered or licensed engineer in some jurisdictions.

🔗 History 🔗 Ancient Near East 🔗 Malta 🔗 Phoenicia

The Cippi of Melqart are a pair of Phoenician marble cippi that were unearthed in Malta under undocumented circumstances and dated to the 2nd century BC. These are votive offerings to the god Melqart, and are inscribed in two languages, Ancient Greek and Phoenician, and in the two corresponding scripts, the Greek and the Phoenician alphabet. They were discovered in the late 17th century, and the identification of their inscription in a letter dated 1694 made them the first Phoenician writing to be identified and published in modern times. Because they present essentially the same text (with some minor differences), the cippi provided the key to the modern understanding of the Phoenician language. In 1758, the French scholar Jean-Jacques Barthélémy relied on their inscription, which used 17 of the 22 letters of the Phoenician alphabet, to decipher the unknown language.

The tradition that the cippi were found in Marsaxlokk was only inferred by their dedication to Heracles, whose temple in Malta had long been identified with the remains at Tas-Silġ. The Grand Master of the Order of the Knights Hospitaller, Fra Emmanuel de Rohan-Polduc, presented one of the cippi to the Académie des Inscriptions et Belles-Lettres in 1782. This cippus is currently in the Louvre Museum in Paris, while the other rests in the National Museum of Archaeology in Valletta, Malta. The inscription is known as KAI 47.
