π 20 years ago Far Cry was released
Far Cry is a 2004 first-person shooter game developed by Crytek and published by Ubisoft. It is the first installment in the Far Cry franchise. Set on a mysterious tropical archipelago, the game follows Jack Carver, a former American special operations forces operative, as he searches for journalist Valerie Constantine, who accompanied him to the islands but went missing after their boat was destroyed by mercenaries. As Jack explores the islands, he begins to discover the horrific genetic experiments being conducted on the local wildlife and must confront the mad scientist behind them.
The game was the first to use Crytek's CryEngine, and was designed as an open-ended first-person shooter, though it lacks most of the freedom its successors would offer to the player. While players can freely explore the game's world like in later Far Cry titles, they are most often discouraged from doing so due to the linear structure of missions and the lack of side content. Despite this, the gameplay formula established in Far Cryβplacing the player in a foreign environment occupied by enemy forces where they must use various weapons and tools, as well as their surroundings to overcome any threatβwould prove essential in defining the series' identity going forward.
Far Cry was released for Microsoft Windows in March 2004 to generally positive reviews, being praised for its visuals, gameplay mechanics, and the level of freedom given to players. The game was also a commercial success, selling over 730,000 units within four months of release and over 2.5 million units in its lifetime. The success of Far Cry led to a series of standalone sequels developed by Ubisoft, starting with Far Cry 2 in 2008. A remake of the game with a different storyline and new mechanics, Far Cry Instincts, was released for the Xbox in 2005, and for the Xbox 360 in 2006 as part of the Far Cry Instincts: Predator compilation. A loose film adaptation was released in 2008. The original version of Far Cry, updated with HD graphics, was re-released under the title Far Cry Classic for the PlayStation 3 and Xbox 360 in 2014.

π 1999 Loomis Truck Robbery
The 1999 Loomis truck robbery was a robbery of a Loomis, Fargo & Co. semi-trailer truck on March 24, 1999, as it transported money from Sacramento, California to San Francisco. At some point during the transit, one or more robbers boarded the truck, cut a hole in the roof, removed approximately 2.3 million dollars, and exited the truck with the money, completely evading detection by the truck's driver and guards. The robbery was not discovered until after the truck arrived at its destination. No suspects were ever identified by authorities and the robbery is now a cold case. Even the exact tools and methods used by robber or robbers were never conclusively determined.

π Beer distribution game
The beer distribution game (also known as the beer game) is a type of gamification that is used to experience typical coordination problems of a supply chain process. It reflects a role-play simulation where several participants play with each other. The game represents a supply chain with a non-coordinated process where problems arise due to lack of information sharing. This game outlines the importance of information sharing, supply chain management and collaboration throughout a supply chain process. Due to lack of information, suppliers, manufacturers, sales people and customers often have an incomplete understanding of what the real demand of an order is. The most interesting part of the game is that each group has no control over another part of the supply chain. Therefore, each group has only significant control over their own part of the supply chain. Each group can highly influence the entire supply chain by ordering too much or too little which can lead to a bullwhip effect. Therefore, the order taking of a group also highly depends on decisions of the other groups.

π Hashlife
Hashlife is a memoized algorithm for computing the long-term fate of a given starting configuration in Conway's Game of Life and related cellular automata, much more quickly than would be possible using alternative algorithms that simulate each time step of each cell of the automaton. The algorithm was first described by Bill Gosper in the early 1980s while he was engaged in research at the Xerox Palo Alto Research Center. Hashlife was originally implemented on Symbolics Lisp machines with the aid of the Flavors extension.

π Hoxne Hoard
The Hoxne Hoard ( HOK-sΙn) is the largest hoard of late Roman silver and gold discovered in Britain, and the largest collection of gold and silver coins of the fourth and fifth centuries found anywhere within the former Roman Empire. It was found by Eric Lawes, a metal detectorist in the village of Hoxne in Suffolk, England in 1992. The hoard consists of 14,865 Roman gold, silver, and bronze coins and approximately 200 items of silver tableware and gold jewellery. The objects are now in the British Museum in London, where the most important pieces and a selection of the rest are on permanent display. In 1993, the Treasure Valuation Committee valued the hoard at Β£1.75 million (about Β£3.79Β million in 2021).
The hoard was buried in an oak box or small chest filled with items in precious metal, sorted mostly by type, with some in smaller wooden boxes and others in bags or wrapped in fabric. Remnants of the chest and fittings, such as hinges and locks, were recovered in the excavation. The coins of the hoard date it after AD 407, which coincides with the end of Britain as a Roman province. The owners and reasons for burial of the hoard are unknown, but it was carefully packed and the contents appear consistent with what a single very wealthy family might have owned. It is likely that the hoard represents only a part of the wealth of its owner, given the lack of large silver serving vessels and of some of the most common types of jewellery.
The Hoxne Hoard contains several rare and important objects, such as a gold body-chain and silver-gilt pepper-pots (piperatoria), including the Empress pepper pot. The hoard is also of particular archaeological significance because it was excavated by professional archaeologists with the items largely undisturbed and intact. The find helped to improve the relationship between metal detectorists and archaeologists, and influenced a change in English law regarding finds of treasure.

π 2007 Boston Mooninite Panic
On the morning of January 31, 2007, the Boston Police Department and the Boston Fire Department mistakenly identified battery-powered LED placards depicting the Mooninites, characters from the Adult Swim animated television series Aqua Teen Hunger Force, as improvised explosive devices (IEDs), leading to a massive panic. Placed throughout Boston, Massachusetts, and the surrounding cities of Cambridge and Somerville by Peter "Zebbler" Berdovsky and Sean Stevens, these devices were part of a nationwide guerrilla marketing advertising campaign for Aqua Teen Hunger Force Colon Movie Film for Theaters.
The massive panic led to controversy and criticism from U.S. media sources, including The Boston Globe, Los Angeles Times, Fox News, The San Francisco Chronicle, The New York Times, CNN, and The Boston Herald. Some ridiculed the city's response to the devicesβincluding the arrests of the two men hired to place the placards around the areaβas disproportionate and indicative of a generation gap between city officials and the younger residents of Boston, at whom the ads were targeted. Several sources noted that the hundreds of officers in the Boston police department or city emergency planning office on scene were unable to identify the figure depicted for several hours until a young staffer at Mayor Thomas Menino's office saw the media coverage and recognized the figures.
After the devices were removed, the Boston Police Department stated in its defense that the ad devices shared some similarities with improvised explosive devices, with them also discovering an identifiable power source, a circuit board with exposed wiring, and electrical tape. Investigators were not mollified by the discovery that the devices were not explosive in nature, stating they still intended to determine "if this event was a hoax or something else entirely". Although city prosecutors eventually concluded there was no ill intent involved in the placing of the ads, the city continues to refer to the event as a "bomb hoax" (implying intent) rather than a "bomb scare".
Reflecting years later, various academics and media sources have characterized the phenomenon as a form of social panic. Gregory Bergman wrote in his 2008 book BizzWords that the devices were basically a self-made form of the children's toy Lite-Brite. Bruce Schneier wrote in his 2009 book Schneier on Security that Boston officials were "ridiculed" for their overreaction to the incident. In his 2009 book Secret Agents, historian and communication professor Jeremy Packer discussed a cultural phenomenon called the "panic discourse" and described the incident as a "spectacular instance of this panic". In a 2012 article, The Boston Phoenix called the incident the "Great Mooninite Panic of 2007". A 2013 publication by WGBH wrote that the majority of Boston youth thought that the arrests of two men who placed devices were not justified.

π Falkirk Wheel
The Falkirk Wheel is a rotating boat lift in central Scotland, connecting the Forth and Clyde Canal with the Union Canal. The lift is named after Falkirk, the town in which it is located. It reconnects the two canals for the first time since the 1930s. It opened in 2002 as part of the Millennium Link project.
The plan to regenerate central Scotland's canals and reconnect Glasgow with Edinburgh was led by British Waterways with support and funding from seven local authorities, the Scottish Enterprise Network, the European Regional Development Fund, and the Millennium Commission. Planners decided early on to create a dramatic 21st-century landmark structure to reconnect the canals, instead of simply recreating the historic lock flight.
The wheel raises boats by 24 metres (79Β ft), but the Union Canal is still 11 metres (36Β ft) higher than the aqueduct which meets the wheel. Boats must also pass through a pair of locks between the top of the wheel and the Union Canal. The Falkirk Wheel is the only rotating boat lift of its kind in the world, and one of two working boat lifts in the United Kingdom, the other being the Anderton Boat Lift.

π Sexy Son Hypothesis
The sexy son hypothesis in evolutionary biology and sexual selection, proposed by Patrick J. Weatherhead and Raleigh J. Robertson of Queen's University in Kingston, Ontario in 1979, states that a female's ideal mate choice among potential mates is one whose genes will produce males with the best chance of reproductive success. This implies that other benefits the father can offer the mother or offspring are less relevant than they may appear, including his capacity as a parental caregiver, territory and any nuptial gifts. Fisher's principle means that the sex ratio (except in certain eusocial insects) is always near 1:1 between males and females, yet what matters most are her "sexy sons'" future breeding successes, more likely if they have a promiscuous father, in creating large numbers of offspring carrying copies of her genes. This sexual selection hypothesis has been researched in species such as the European pied flycatcher.
