πŸ”— Exorbitant Privilege

πŸ”— Economics

The term exorbitant privilege (privilège exorbitant in French) refers to the benefits the United States has due to its own currency (the US dollar) being the international reserve currency. For example, the US would not face a balance of payments crisis, because their imports are purchased in their own currency. Exorbitant privilege as a concept cannot refer to currencies that have a regional reserve currency role, only to global reserve currencies.

Academically, the exorbitant privilege literature analyzes two empirical puzzles, the position puzzle and the income puzzle. The position puzzle refers to the difference between the (negative) U.S. net international investment position (NIIP) and the accumulated U.S. current account deficits, the former being much smaller than the latter. The income puzzle is that despite a deeply negative NIIP, the U.S. income balance is positive, i.e. despite having much more liabilities than assets, earned income is higher than interest expenses.

πŸ”— Body Doubling

πŸ”— Disability

Body doubling or parallel working is a strategy used to initiate and complete tasks, such as household chores or writing and other computer tasks. It involves the physical presence, virtual presence through a phone call, videotelephony or social media presence, of someone with whom one shares their goals, which makes it more likely to achieve them. For some people, it works best to both do similar tasks, while for others, just being in the same (virtual) room is enough.

It was partially popularized by those with attention deficit hyperactivity disorder (ADHD) to help manage symptoms. Its usefulness has also been noted by those with autism, but efficacy is not clearly known as long term studies have not been conducted on the topic. In 2023, J. Russel Ramsay, professor of clinical psychiatry at the Perelman School of Medicine and co-director of the ADHD treatment and research program of the University of Pennsylvania, noted that, while extensive research on the strategy's effect on productivity doesn't exist, "the idea of externalizing motivation is a longstanding evidence-based mechanism for managing ADHD."

ADHD body doubling comes into play allowing individuals with ADHD to perform and complete tasks more easily and with less distractions, where otherwise they might struggle more. "ADHD body doubling is a productivity strategy used by individuals with ADHD to finish possibly annoying jobs while having another person beside them."

Body doubling is said to aid individuals with focus and productivity while working. Another person, known as a 'body double' sits alongside the individual with ADHD to help them focus while completing a certain task. The role of this individual is to not partake in the task but, more importantly, serve as a support system and create a welcoming environment that allows the individual to focus by reducing any distractions. The idea of body doubling allows for specific reminders to the individual to stay on task which helps alleviate the symptoms of ADHD.

πŸ”— Argumentation Theory

πŸ”— Law πŸ”— Philosophy πŸ”— Philosophy/Logic πŸ”— Writing

Argumentation theory is the interdisciplinary study of how conclusions can be supported or undermined by premises through logical reasoning. With historical origins in logic, dialectic, and rhetoric, argumentation theory includes the arts and sciences of civil debate, dialogue, conversation, and persuasion. It studies rules of inference, logic, and procedural rules in both artificial and real-world settings.

Argumentation includes various forms of dialogue such as deliberation and negotiation which are concerned with collaborative decision-making procedures. It also encompasses eristic dialogue, the branch of social debate in which victory over an opponent is the primary goal, and didactic dialogue used for teaching. This discipline also studies the means by which people can express and rationally resolve or at least manage their disagreements.

Argumentation is a daily occurrence, such as in public debate, science, and law. For example in law, in courts by the judge, the parties and the prosecutor, in presenting and testing the validity of evidences. Also, argumentation scholars study the post hoc rationalizations by which organizational actors try to justify decisions they have made irrationally.

Argumentation is one of four rhetorical modes (also known as modes of discourse), along with exposition, description, and narration.

πŸ”— The Barnacle Goose Myth

πŸ”— Birds πŸ”— Mythology

The barnacle goose myth is a widely-reported historical misconception about the breeding habits of the barnacle goose (Branta leucopsis) and brant goose (Branta bernicla). One version of the myth is that these geese emerge fully formed from goose barnacles (Cirripedia). Other myths exist about how the barnacle goose supposedly emerges and grows from matter other than bird eggs.

The etymology of the term "barnacle" suggests Latin, Old English, and French roots. There are few references in pre-Christian books and manuscripts – some Roman or Greek. The main vector for the myth into modern times was monastic manuscripts and in particular the bestiary.

The myth owes its long-standing popularity to an early ignorance of the migration patterns of geese. Early medieval discussions of the nature of living organisms were often based on myths or genuine ignorance of what is now known about phenomena such as bird migration. It was not until the late 19th century that bird migration research showed that such geese migrate northwards to nest and breed in Greenland or northern Scandinavia.

πŸ”— Compound File Binary Format

πŸ”— Computing

Compound File Binary Format (CFBF), also called Compound File, Compound Document format, or Composite Document File V2 (CDF), is a compound document file format for storing numerous files and streams within a single file on a disk. CFBF is developed by Microsoft and is an implementation of Microsoft COM Structured Storage. The file format is used for storing storage objects and stream objects in a hierarchical structure within a single file.

Microsoft has opened the format for use by others and it is now used in a variety of programs from Microsoft Word and Microsoft Access to Business Objects. It also forms the basis of the Advanced Authoring Format.

πŸ”— Toroidal Propeller

πŸ”— United States πŸ”— Aviation πŸ”— Aviation/aircraft πŸ”— Aviation/aircraft engine πŸ”— Ships

A toroidal propeller is a type of propeller that is ring-shaped with each blade forming a closed loop. The propellers are significantly quieter at audible frequency ranges, between 20Β Hz and 20Β kHz, while generating comparable thrust to traditional propellers. In practice, toroidal propellers reduce noise pollution in both aviation and maritime transport.

πŸ”— Deniable Encryption

πŸ”— Cryptography πŸ”— Cryptography/Computer science

In cryptography and steganography, plausibly deniable encryption describes encryption techniques where the existence of an encrypted file or message is deniable in the sense that an adversary cannot prove that the plaintext data exists.

The users may convincingly deny that a given piece of data is encrypted, or that they are able to decrypt a given piece of encrypted data, or that some specific encrypted data exists. Such denials may or may not be genuine. For example, it may be impossible to prove that the data is encrypted without the cooperation of the users. If the data is encrypted, the users genuinely may not be able to decrypt it. Deniable encryption serves to undermine an attacker's confidence either that data is encrypted, or that the person in possession of it can decrypt it and provide the associated plaintext.

In their pivotal 1996 paper, Ran Canetti, Cynthia Dwork, Moni Naor, and Rafail Ostrovsky introduced the concept of deniable encryption, a cryptographic breakthrough that ensures privacy even under coercion. This concept allows encrypted communication participants to plausibly deny the true content of their messages. Their work lays the foundational principles of deniable encryption, illustrating its critical role in protecting privacy against forced disclosures. This research has become a cornerstone for future advancements in cryptography, emphasizing the importance of deniable encryption in maintaining communication security. The notion of deniable encryption was used by Julian Assange and Ralf Weinmann in the Rubberhose filesystem.

πŸ”— Hyperion (Tree)

πŸ”— California πŸ”— Plants

Hyperion is a coast redwood (Sequoia sempervirens) in California that is the world's tallest known living tree, measured at 116.07 metres (380.8Β ft) tall in 2019.

Hyperion was discovered on AugustΒ 25, 2006, by naturalists Chris Atkins and Michael Taylor. The tree height of 115.55Β m (379.1Β ft) was verified by Stephen Sillett in 2006 using both a laser range finder and a fiberglass tape to measure the tree from the base to the crown. The tree has grown since then to reach 116.07 metres (380.8Β ft) recorded in 2019. Hyperion was found in a remote area of Redwood National Park, inside of the originally designated park boundaries of 1968. The park also houses the second-, fourth- and fifth-tallest known trees, coast redwoods named Helios, Icarus, and Daedalus, which respectively measured 377, 371 and 363 feet in 2022.

The tree was named after the titan Hyperion from Greek mythology.

Hyperion is estimated to be between 600 and 800 years old and contain 530Β m3 (18,600Β cuΒ ft) of wood.

The exact location of Hyperion is nominally secret but is available via internet search. However, in JulyΒ 2022, the Redwood Park superintendent closed the entire area around the tree, citing "devastation of the habitat surrounding Hyperion" caused by visitors. Its base was trampled by the overuse and as a result ferns no longer grow around the tree. Anyone who gets too close could face up to six months in jail and a $5,000 maximum fine.

πŸ”— Parnassus plays

πŸ”— Theatre πŸ”— Elizabethan theatre

The Parnassus plays are three satiric comedies, or full-length academic dramas, each divided into five acts. They date from between 1598 and 1602. They were performed in London by students for an audience of students as part of the Christmas festivities of St John's College at Cambridge University. It is not known who wrote them.

The titles of the three plays are

  • The Pilgrimage to Parnassus
  • The Return from Parnassus
  • The Return from Parnassus: Or the Scourge of Simony

The second and third plays are sometimes referred to as Part One and Part Two of The Return from Parnassus.

The trilogy raises an Elizabethan question: After college – what comes next? Francis Bacon in his essay "Of Seditions and Troubles" pointed to a 16th-century problem – universities were producing more scholars than there were opportunities for them. The University Wits – Lily, Marlowe, Green, Peele, Nashe and Lodge – were scholars who found employment in theatre, not perhaps their first choice, but there was little else for them. Their great education tended to discourage them from taking up the humble trades of their fathers. The Parnassus plays may not provide a solution, but they at least illustrated the fears of such ambitious young scholastic dreamers.

For the most part, the plays follow the experiences of two students, Philomusus and Studioso. The first play tells the story of two pilgrims on a journey to Parnassus. The plot is an allegory understood to represent the story of two students progressing through the traditional course of education known as the trivium. The accomplishment of their education is represented by Mount Parnassus. The second play drops the allegory and describes the two graduates' unsuccessful attempts to make a living, as does the third play, which is the only one that was contemporaneously published. New in the third play is the serious treatment of issues regarding censorship.

It has been said that this trilogy of plays "in originality and breadth of execution, and in complex relationship to the academic, literary, theatrical and social life of the period, ranks supreme among the extant memorials of the university stage", and that they are "among the most inexplicably neglected key documents of Shakespeare's age".

πŸ”— Asus Eee PC

πŸ”— Computing πŸ”— Linux

The ASUS Eee PC is a netbook computer line from Asus, and a part of the ASUS Eee product family. At the time of its introduction in late 2007, it was noted for its combination of a lightweight, Linux-based operating system, solid-state drive (SSD), and relatively low cost. Newer models added the options of Microsoft Windows operating system and rotating media hard disk drives (HDD), and initially retailed for up to 500 euros.

The first Eee PC was a milestone in the personal computer business, launching the netbook category of small, low-cost laptops in the West (in Japan, subnotebooks had long been a staple in computing). According to Asus, the name Eee derives from "the three Es", an abbreviation of its advertising slogan for the device: "Easy to learn, Easy to work, Easy to play".

In January 2013, ASUS officially ended production of their Eee PC series, citing declining sales due to consumers favoring tablets and Ultrabooks over netbooks. However, they subsequently restarted the line with the release of the EeeBook series in 2015.
