The Kee Bird was a United States Army Air Forces Boeing B-29 Superfortress, serial 45-21768, of the 46th Reconnaissance Squadron, that became marooned after making an emergency landing in northwest Greenland during a secret Cold War spying mission on 21 February 1947. While the entire crew was safely evacuated after spending three days in the isolated Arctic tundra, the aircraft itself was left at the landing site. It lay there undisturbed until 1994, when a privately funded mission was launched to repair and return it. During the attempted recovery, a fire broke out, resulting in the destruction and loss of the airframe on the ground.

In game design, balance is the concept and the practice of tuning a game's rules, usually with the goal of preventing any of its component systems from being ineffective or otherwise undesirable when compared to their peers. An unbalanced system represents wasted development resources at the very least, and at worst can undermine the game's entire ruleset by making important roles or tasks impossible to perform.

🔗 Board and table games

Uckers is a two- or four-player board game traditionally played in the Royal Navy and has spread to many of the other arms of the UK Armed Forces as well as to, mainly Commonwealth Forces. It can now be found also in the Royal Marines, Army Air Corps, Royal Canadian Navy, Royal New Zealand Navy, Royal Australian Navy, Royal Australian Air Force (RAAF), Royal Dutch Navy, and the Royal Air Force (RAF). It is believed to originate in the 18th/19th centuries from the Indian game Pachisi, although the first reference to it in print does not appear until 1946. It is mentioned in a diary by EJF Records (served 1928-1950) in 1937 as Huckers. Uckers is generally played using the rules stated below, but these will vary from one branch of the Royal Navy to another, most famously with the WAFU Rules of the Fleet Air Arm. Where those branches of the RN have worked with the other Armed Forces usually has dictated what rules the new playing Service use; why fellow aviators tend to play under WAFU Rules for example.

It is also played in units of the Army Air Corps (United Kingdom) where it was introduced by aircraft technicians on loan from the Fleet Air Arm in the late 1950s/early 1960s. Uckers boards can now also be found in most RAF Squadron crewroom, where the game has caught on, especially with the Aircraft Technicians. Most RAAF crew rooms feature uckers boards also. In addition to the units services, units mentioned, uckers was also played by units in the Royal Artillery, particularly meteorologists and LifeFlight Toowoomba Rescue Helicopter crews aka Rescue 588. The current and now 7-time world champion is Queenslander Mark Arthur. In the UK the Pusser's Rum World 'Uckers championships have been played for the last 5 years at various ROYAL NAVAL MUSEUMS, the most being notable being 2017 when the final was played on Nelson's Flagship HMS VICTORY and was won by the'timber shifters' Wally Blagden and David Clark both ex RN. The next Pusser's Rum WORLD 'uckers' championships are being played in the Explosion Museum Gosport 26 October 2019. Wally andDavid are also current HMS GANGES Champions won in April 2019 Update Wally Blagden and Dave Clark the 'Timbershifters' have won the 2019 Championships. Knock knock. The chicken

It is similar to the board game Ludo and is based on the same principles; getting four player pieces around the board before the opposition. The whole point of Uckers is to get all player pieces home before the opponent does. However, greater glory is attached to achieving all pieces home without the opponent getting any home at all—this is known as an 8 piecer. The ultimate win is when the player gets all their pieces home and the opponent has all their pieces still in the base—this is called an 8 piece in harbour, or an eight-piece dicking and merits the unfortunate player's name to be recorded on the reverse of the board.

🔗 Biography 🔗 Computing

Francesco Vianello (30 August 1952 – 3 May 2009), better known by his nickname Fravia (sometimes +Fravia or Fravia+), was a software reverse engineer, and hacker, known for his web archive of reverse engineering techniques and papers. He is also known for his work on steganography. He had taught on subjects such as data mining, anonymity, stalking, klebing, advertisement reversing and ad-busting.

Fravia spoke six languages (including Latin) and had a degree in the history of the early Middle Ages. He was an expert in linguistics-related informatics. For five years he made available a large quantity of material related to reverse engineering through his website, which also hosted the advice of reverse engineering experts, known as reversers, who provided tutorials and essays on how to hack software code as well as advice related to the assembly and disassembly of applications, and software protection reversing.

Fravia was a professor at the High Cracking University (+HCU), founded by Old Red Cracker (+ORC), a legendary figure in reverse engineering, to conduct research into Reverse Code Engineering. The addition of the "+" sign in front of the nickname of a reverser signified membership in the +HCU. His website was known as "+Fravia's Pages of Reverse Engineering" and he used it to challenge programmers as well as the wider society to "reverse engineer" the "brainwashing of a corrupt and rampant materialism". In its heyday, his website was receiving millions of visitors per year and its influence was "widespread".

His web presence dates from 1995 when he first got involved in research related to reverse code engineering (RCE). In 2000 he changed his focus and concentrated on advanced internet search methods and the reverse engineering of search engine code.

His websites "www.fravia.com" and "www.searchlores.org" contained a large amount of specialised information related to data mining. His website "www.searchlores.org" has been called a "very useful instrument for searching the web", and his "www.fravia.com" site has been described as "required reading for any spy wanting to go beyond simple Google searches."

🔗 Lists 🔗 History of Science 🔗 Science

Historians and sociologists have remarked the occurrence, in science, of "multiple independent discovery". Robert K. Merton defined such "multiples" as instances in which similar discoveries are made by scientists working independently of each other. "Sometimes," writes Merton, "the discoveries are simultaneous or almost so; sometimes a scientist will make a new discovery which, unknown to him, somebody else has made years before."

Commonly cited examples of multiple independent discovery are the 17th-century independent formulation of calculus by Isaac Newton, Gottfried Wilhelm Leibniz and others, described by A. Rupert Hall; the 18th-century discovery of oxygen by Carl Wilhelm Scheele, Joseph Priestley, Antoine Lavoisier and others; and the theory of the evolution of species, independently advanced in the 19th century by Charles Darwin and Alfred Russel Wallace.

Multiple independent discovery, however, is not limited to such famous historic instances. Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science.

Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together.

A distinction is drawn between a discovery and an invention, as discussed for example by Bolesław Prus. However, discoveries and inventions are inextricably related, in that discoveries lead to inventions, and inventions facilitate discoveries; and since the same phenomenon of multiplicity occurs in relation to both discoveries and inventions, this article lists both multiple discoveries and multiple inventions.

🔗 Numbers

In number theory, a narcissistic number (also known as a pluperfect digital invariant (PPDI), an Armstrong number (after Michael F. Armstrong) or a plus perfect number) in a given number base ${\displaystyle b}$ is a number that is the sum of its own digits each raised to the power of the number of digits.

🔗 Syria

The Hurrian songs are a collection of music inscribed in cuneiform on clay tablets excavated from the ancient Amorite-Canaanite city of Ugarit, a headland in northern Syria, which date to approximately 1400 BCE. One of these tablets, which is nearly complete, contains the Hurrian hymn to Nikkal (also known as the Hurrian cult hymn or A Zaluzi to the Gods, or simply h.6), making it the oldest surviving substantially complete work of notated music in the world. While the composers' names of some of the fragmentary pieces are known, h.6 is an anonymous work.

🔗 Computing 🔗 Computing/Computer hardware

N8VEM was a homebrew computing project. It featured a variety of free and open hardware and software. N8VEM builders made their own homebrew computer systems for themselves and shared their experiences with other homebrew computer hobbyists. N8VEM homebrew computer components are made in the style of vintage computers of the mid to late 1970s and early 1980s using a mix of classic and modern technologies. They are designed with ease of amateur assembly in mind.

In November 2015 the N8VEM project was ended by its creator Andrew Lynch and the community reconvened under the new name of Retrobrew Computers.
