🔗 Economics 🔗 Robotics 🔗 Game theory

Mechanism design is a field in economics and game theory that takes an objectives-first approach to designing economic mechanisms or incentives, toward desired objectives, in strategic settings, where players act rationally. Because it starts at the end of the game, then goes backwards, it is also called reverse game theory. It has broad applications, from economics and politics (markets, auctions, voting procedures) to networked-systems (internet interdomain routing, sponsored search auctions).

Mechanism design studies solution concepts for a class of private-information games. Leonid Hurwicz explains that 'in a design problem, the goal function is the main "given", while the mechanism is the unknown. Therefore, the design problem is the "inverse" of traditional economic theory, which is typically devoted to the analysis of the performance of a given mechanism.' So, two distinguishing features of these games are:

• that a game "designer" chooses the game structure rather than inheriting one
• that the designer is interested in the game's outcome

The 2007 Nobel Memorial Prize in Economic Sciences was awarded to Leonid Hurwicz, Eric Maskin, and Roger Myerson "for having laid the foundations of mechanism design theory".

This Man, according to a website created in 2008 by Italian marketer Andrea Natella named Ever Dream This Man?, was a person who was claimed to have been repeatedly seen in dreams by the whole world since 2006, but was never found in the real world. Natella created the site in 2008, but it was not until October 2009 that it gained attention from the press and online internet users. This Man's notoriety spawned several internet memes that spoofed flyers of the website, references in films and television shows like The X-Files, and a manga series based on the hoax by Weekly Shonen Magazine.

Bicameralism (the condition of being divided into "two-chambers") is a hypothesis in psychology that argues that the human mind once operated in a state in which cognitive functions were divided between one part of the brain which appears to be "speaking", and a second part which listens and obeys—a bicameral mind. The term was coined by Julian Jaynes, who presented the idea in his 1976 book The Origin of Consciousness in the Breakdown of the Bicameral Mind, wherein he made the case that a bicameral mentality was the normal and ubiquitous state of the human mind as recently as 3,000 years ago, near the end of the Mediterranean bronze age.

🔗 Video games 🔗 Comics 🔗 Comics/Superman

Superman: The New Superman Adventures, commonly referred to as Superman 64, is an action-adventure game developed and published by Titus Interactive for the Nintendo 64 and based on the television series Superman: The Animated Series. Released in North America on May 31, 1999, and in Europe on July 23, 1999, it is the first 3D Superman game.

In the game, Lex Luthor has trapped Jimmy Olsen, Lois Lane, and Professor Hamilton in a virtual reality version of Metropolis that he created with the help of Brainiac, leaving it up to Superman to save them and break apart the virtual world. The game shifts between outdoor levels where the player flies through rings while saving civilians, and indoor levels where the player looks for access cards, activates computers, and fights villains such as Brainiac, Mala, Metallo, Darkseid, and Parasite.

The development of Superman began in 1997 and was largely hampered by constraints between Titus and the game's licensors, Warner Bros. and DC Comics, leaving little room for polishing the gameplay. BlueSky Software attempted to redo the game for the PlayStation, but this version was ultimately canceled, as Titus's license with Warner Bros. had expired by the time it was completed. With three E3 presentations and positive press coverage before its release, Superman 64 was released to strong sales and positive consumer reception; however, critical reviews were extremely negative, claiming it to be one of the worst video games ever made and panning its unresponsive controls, technical flaws, repetitive gameplay, overuse of distance fog, and poor graphics.

The First Council of Nicaea ( ny-SEE-ə; Ancient Greek: Σύνοδος τῆς Νικαίας, romanized: Sýnodos tês Nikaías) was a council of Christian bishops convened in the Bithynian city of Nicaea (now İznik, Turkey) by the Roman Emperor Constantine I. The Council of Nicaea met from May until the end of July 325.

This ecumenical council was the first of many efforts to attain consensus in the church through an assembly representing all Christendom. Hosius of Corduba may have presided over its deliberations. Its main accomplishments were settlement of the Christological issue of the divine nature of God the Son and his relationship to God the Father, the construction of the first part of the Nicene Creed, mandating uniform observance of the date of Easter, and promulgation of early canon law.

🔗 Computing

Amoeba is a distributed operating system developed by Andrew S. Tanenbaum and others at the Vrije Universiteit Amsterdam. The aim of the Amoeba project was to build a timesharing system that makes an entire network of computers appear to the user as a single machine. Development at the Vrije Universiteit was stopped: the source code of the latest version (5.3) was last modified on 30 July 1996.

The Python programming language was originally developed for this platform.

A sex drive-in or sex box is a car garage (or similarly shielded location) that is designed to allow prostitution to take place using cars, and can be found in a few countries in Europe. Generally the facilities are created by local authorities to put some control on where prostitution occurs and to provide increased safety.

On 25 May 2003, a Boeing 727, registered N844AA, was stolen at Quatro de Fevereiro Airport, Luanda, Angola. Its disappearance prompted a worldwide search by the United States' Federal Bureau of Investigation (FBI) and Central Intelligence Agency (CIA). No trace of the aircraft has since been found.

🔗 Health and fitness

Calisthenics (American English) or callisthenics (British English) is a form of exercise consisting of a variety of movements that exercise large muscle groups (gross motor movements), such as running, standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises. They are intended to increase strength, fitness, and flexibility, through movements such as pulling, pushing, bending, jumping, or swinging, using one's body weight for resistance. Calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility, and coordination.

Urban calisthenics is a form of street workout; calisthenics groups perform exercise routines in urban areas. Individuals and groups train to perform advanced calisthenics skills such as muscle-ups, levers, and various freestyle moves such as spins and flips.

Sports teams and military units often perform leader-directed group calisthenics as a form of synchronized physical training (often including a customized "call and response" routine) to increase group cohesion and discipline. Calisthenics is also popular as a component of physical education in primary and secondary schools over much of the globe.

In addition to general fitness, calisthenic exercises are often used as baseline physical evaluations for military organizations around the world. Two examples are the U.S. Army Physical Fitness Test and the U.S.M.C. Physical Fitness Test.
