πŸ”— Kindertransport

πŸ”— Germany πŸ”— Jewish history πŸ”— Adoption, fostering, orphan care and displacement

The Kindertransport (German for "children's transport") was an organised rescue effort of children from Nazi-controlled territory that took place in 1938–1939 during the nine months prior to the outbreak of the Second World War. The United Kingdom took in nearly 10,000 children, most of them Jewish, from Germany, Austria, Czechoslovakia, Poland, and the Free City of Danzig. The children were placed in British foster homes, hostels, schools, and farms. Often they were the only members of their families who survived the Holocaust that was to come. The programme was supported, publicised, and encouraged by the British government, which waived the visa immigration requirements that were not within the ability of the British Jewish community to fulfil. The British government placed no numerical limit on the programme; it was the start of the Second World War that brought it to an end, by which time about 10,000 kindertransport children had been brought to the country.

Smaller numbers of children were taken in via the programme by the Netherlands, Belgium, France, Sweden, and Switzerland. The term "kindertransport" may also be applied to the rescue of mainly Jewish children from Nazi German territory to the Netherlands, Belgium, and France. An example is the 1,000 Chateau de La Hille children who went to Belgium. However, most often the term is restricted to the organised programme of the United Kingdom.

The Central British Fund for German Jewry (now World Jewish Relief) was established in 1933 to support in whatever way possible the needs of Jews in Germany and Austria.

In the United States, the Wagner–Rogers Bill was introduced in Congress, which would have increased the quota of immigrants by bringing to the U.S. a total of 20,000 refugee children, but it did not pass.

πŸ”— Expert System

πŸ”— Computer science πŸ”— Systems πŸ”— Human–Computer Interaction

In artificial intelligence, an expert system is a computer system emulating the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code. The first expert systems were created in the 1970s and then proliferated in the 1980s. Expert systems were among the first truly successful forms of artificial intelligence (AI) software. An expert system is divided into two subsystems: the inference engine and the knowledge base. The knowledge base represents facts and rules. The inference engine applies the rules to the known facts to deduce new facts. Inference engines can also include explanation and debugging abilities.

πŸ”— Star Trek: Phase II

πŸ”— Television πŸ”— Star Trek

Star Trek: Phase II was the initial working title for what officially became titled Star Trek II, an unproduced American science fiction television series created by Gene Roddenberry as a sequel to (and continuation of) the original Star Trek, which had run from 1966 to 1969. The plans for the series were first developed after several failed attempts to create a feature film based on the property, coupled with plans for a Paramount Television Service (PTS) as a fourth broadcast television network in the United States.

Both PTS and the Star Trek revival were announced in early June 1977, with PTS to debut as one evening of programming each Saturday night and to gradually expand to other nights; a strategy successfully employed by the Fox Broadcasting Company a decade later. Star Trek: Phase II was to be the flagship show, and be broadcast at 8pm EST, followed by a movie of the week starting at 9pm. The initial order was for a two-hour pilot, followed by 13 hour-long episodes.

With the exception of Leonard Nimoy as Mr. Spock, who had ongoing disputes with Roddenberry and Paramount, the entire regular and recurring cast of The Original Series were contracted to return, notably William Shatner as Captain Kirk. Three new and younger regular characters were created, science officer Lt. Xon, navigator Lt. Ilia, and ship's executive officer Willard Decker. Xon, Decker and Ilia were later influential in the development of characters on Star Trek: The Next Generation, and two of the scripts written for Phase II would be re-developed for use in that series.

Behind the cameras, Roddenberry recruited Trek-novices Harold Livingston and Robert Goodwin as producers. Veterans of The Original Series were few, and included costume designer William Ware Theiss and illustrator Mike Minor. Art director Matt Jefferies was otherwise employed and brought in as a "technical advisor" and to update the design of the starship USS Enterprise. Special effects (on set) were to be by Jim Rugg. Science fiction novelist Alan Dean Foster received the assignment to write the story outline for the two-hour pilot, but, with a looming production deadline and unable to find a suitable writer to develop this story into a teleplay, Harold Livingston took on the writing job himself. Of the remaining 12 script assignments handed out, about half were to veterans of The Original Series.

Pre-production began in earnest, with the emphasis on what would be the standing sets of the Enterprise, which differed radically in layout, design and detailing from those for The Original Series. Many costumes and props, too, were designed. Ultimately, Paramount's plans for its network and Star Trek's TV return faltered, as the low anticipated advertising revenues for the Paramount Television Service indicated that it was not viable, and the Paramount Pictures parent company Gulf and Western's chairman, Charles Bluhdorn, refused to back the plan, resulting in the eventual exit of Paramount chief executive officer Barry Diller. In August 1977 Paramount president Michael Eisner announcedβ€”internallyβ€”that the two-hour pilot script was to be the long sought-after feature film story. However, In order to prevent negative publicity, the "cancellation" of the series and network was not immediately disclosed and development of the series and its scripts continued for a further five months, during which time tests were filmed on the incomplete Enterprise sets in widescreen format - a clear indication that whatever Star Trek would be, it would not be a TV movie.

On March 28, 1978, any illusions that Star Trek would be returning to television were ended when Paramount announced that instead of a series it would be producing what became the big budget film titled Star Trek: The Motion Picture (1979), which was itself a massive reworking of the "In Thy Image" two-hour pilot script.

Preproduction work on the series did not entirely go to waste. The standing Enterprise sets would be extensively reworked for the film (and its eventual sequels), and an unfinished admiral's office set's walls became part of the Enterprise cargo deck. However, the visual effects people hired for the feature film decided that the miniatures under construction were not up to the standards of a post-Star Wars feature, and all were scrapped. Director Robert Collins, who had been hired to direct the pilot, and promised he was to direct the feature, was replaced by Robert Wise.

The concept of a "Paramount Network" led by a flagship Star Trek series finally came to fruition in January 1995 when Paramount launched the United Paramount Network (UPN) and the Star Trek: Voyager series.

Folding@home (FAH or F@h) is a distributed computing project aimed to help scientists develop new therapeutics for a variety of diseases by the means of simulating protein dynamics. This includes the process of protein folding and the movements of proteins, and is reliant on simulations run on volunteers' personal computers. Folding@home is currently based at the University of Pennsylvania and led by Greg Bowman, a former student of Vijay Pande.

The project utilizes graphics processing units (GPUs), central processing units (CPUs), and ARM processors like those on the Raspberry Pi for distributed computing and scientific research. The project uses statistical simulation methodology that is a paradigm shift from traditional computing methods. As part of the client–server model network architecture, the volunteered machines each receive pieces of a simulation (work units), complete them, and return them to the project's database servers, where the units are compiled into an overall simulation. Volunteers can track their contributions on the Folding@home website, which makes volunteers' participation competitive and encourages long-term involvement.

Folding@home is one of the world's fastest computing systems. With heightened interest in the project as a result of the COVID-19 pandemic, the system achieved a speed of approximately 1.22 exaflops by late March 2020 and reached 2.43 exaflops by April 12, 2020, making it the world's first exaflop computing system. This level of performance from its large-scale computing network has allowed researchers to run computationally costly atomic-level simulations of protein folding thousands of times longer than formerly achieved. Since its launch on OctoberΒ 1, 2000, Folding@home was involved in the production of 226 scientific research papers. Results from the project's simulations agree well with experiments.

πŸ”— Misirlou

πŸ”— Greece πŸ”— Songs

"Misirlou" (Greek: ΞœΞΉΟƒΞΉΟΞ»ΞΏΟ < Turkish: MΔ±sΔ±rlΔ± 'Egyptian' < Arabic: Ω…Ψ΅Ψ± MiαΉ£r 'Egypt') is a folk song from the Eastern Mediterranean region. The original author of the song is not known, but Arabic, Greek, and Jewish musicians were playing it by the 1920s. The earliest known recording of the song is a 1927 Greek rebetiko/tsifteteli composition. There are also Arabic belly dancing, Albanian, Armenian, Serbian, Persian, Indian and Turkish versions of the song. This song was popular from the 1920s onwards in the Arab American, Armenian American and Greek American communities who settled in the United States.

The song was a hit in 1946 for Jan August, an American pianist and xylophonist nicknamed "the one-man piano duet". It gained worldwide popularity through Dick Dale's 1962 American surf rock version, originally titled "Miserlou", which popularized the song in Western popular culture; Dale's version was influenced by an earlier Arabic folk version played with an oud. Various versions have since been recorded, mostly based on Dale's version, including other surf and rock versions by bands such as the Beach Boys, the Ventures, and the Trashmen, as well as international orchestral easy listening (exotica) versions by musicians such as Martin Denny and Arthur Lyman. Dale's surf rock version was heard in the 1994 film Pulp Fiction.

πŸ”— Internet πŸ”— Computing πŸ”— Blogging πŸ”— Podcasting

RSS (RDF Site Summary or Really Simple Syndication) is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format. Subscribing to RSS feeds can allow a user to keep track of many different websites in a single news aggregator, which constantly monitor sites for new content, removing the need for the user to manually check them. News aggregators (or "RSS readers") can be built into a browser, installed on a desktop computer, or installed on a mobile device.

Websites usually use RSS feeds to publish frequently updated information, such as blog entries, news headlines, episodes of audio and video series, or for distributing podcasts. An RSS document (called "feed", "web feed", or "channel") includes full or summarized text, and metadata, like publishing date and author's name. RSS formats are specified using a generic XML file.

Although RSS formats have evolved from as early as March 1999, it was between 2005 and 2006 when RSS gained widespread use, and the ("") icon was decided upon by several major web browsers. RSS feed data is presented to users using software called a news aggregator and the passing of content is called web syndication. Users subscribe to feeds either by entering a feed's URI into the reader or by clicking on the browser's feed icon. The RSS reader checks the user's feeds regularly for new information and can automatically download it, if that function is enabled.

Edward Arnold Chapman (16 November 1914 – 11 December 1997) was an English criminal and wartime spy. During the Second World War he offered his services to Nazi Germany as a spy and subsequently became a British double agent. His British Secret Service handlers codenamed him Agent Zigzag in acknowledgement of his erratic personal history.

He had a number of criminal aliases known by the British police, amongst them Edward Edwards, Arnold Thompson and Edward Simpson. His German codename was Fritz or, later, after endearing himself to his German contacts, its diminutive form of Fritzchen.

πŸ”— DBOS

DBOS is a Database-Oriented Operating System designed to simplify and improve the scalability, security and resilience of large-scale distributed applications. It started in 2020 as a joint open source project with MIT, Stanford and Carnegie Mellon University, after a brainstorm between Michael Stonebraker and Matei Zaharia on how to scale and improve scheduling and performance of millions of Apache Spark tasks.

The basic idea is to run a multi-node multi-core, transactional, highly-available distributed database, such as VoltDB, as the only application for a microkernel, and then to implement scheduling, messaging, file systems and other operating system services on top of the database.

The architectural philosophy is described by this quote from the abstract of their initial preprint:

All operating system state should be represented uniformly as database tables, and operations on this state should be made via queries from otherwise stateless tasks. This design makes it easy to scale and evolve the OS without whole-system refactoring, inspect and debug system state, upgrade components without downtime, manage decisions using machine learning, and implement sophisticated security features.

Stonebraker claims a variety of security benefits, from a "smaller, less porous attack surface", to the ability to log and analyze how the system state changes in real-time due to the transactional nature of the OS. Recovery from a severe bug or an attack can be as simple as rolling back the database to a previous state. And since the database is already distributed, the complexity of orchestration systems like Kubernetes can be avoided.

A prototype was built with competitive performance to existing systems.
