The EURion constellation is a pattern of symbols found on a number of banknote designs worldwide since about 1996. It is added to help software detect the presence of a banknote in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using color photocopiers. The system is employed on Euros, U.S., dollars, Japanese Yen, and British pounds sterling.
The name ‘EURion constellation’ was coined by German computer scientist, Markus Kuhn, who uncovered the pattern in early 2002 while experimenting with a Xerox photocopier that refused to reproduce banknotes. Technical details regarding the EURion constellation are kept secret by its inventors and users. A patent application suggests that the pattern and detection algorithm were designed at OMRON Corporation, a Japanese electronics company.

A narco submarine (also called a Bigfoot submarine) is a type of custom-made ocean-going self-propelled semi-submersible (SPSS) vessel built by drug traffickers to smuggle drugs. They are especially known to be used by Colombian drug cartel members to export cocaine from Colombia to Mexico, which is often then transported overland to the United States. First detected in 1993, they are popularly called submarines, though typically they are semi-submersibles since they cannot dive; most of the craft is submerged with little more than the cockpit and the exhaust gas pipes above the water.
However, in 2010 Ecuadorian authorities seized a fully functional, completely submersible submarine in the jungles bordering Ecuador and Colombia. This diesel electric submarine had a cylindrical fiberglass hull of 31 meters (102 ft) long, a 3 meter conning tower with periscope, and air conditioning. The vessel had the capacity for about 10 metric tons of cargo, a crew of five or six people, the ability to fully submerge down to 65 feet (20 m), and capable of long-range underwater operation.

Watson, named after IBM’s founder, Thomas J. Watson, is an artificial intelligence program developed to answer questions posed in natural language. Watson competed on the TV game show ‘Jeopardy!’ in 2011, defeating past champions Ken Jennings and Brad Rutter. During the game, Watson had access to 200 million pages of content, including the full text of Wikipedia. Watson consistently outperformed its human opponents on the game’s signaling device, but had trouble responding to a few categories, notably those having short clues containing only a few words.
The original Watson was made up of a cluster of 2880 POWER7 processor cores and 16 Terabytes of RAM. IBM’s master inventor and senior consultant Tony Pearson estimated Watson’s hardware cost about $3 million and with 80 TeraFLOPs would be placed 94th on the Top 500 Supercomputers list in 2011. In 2013, IBM announced that Watson software system’s first commercial application would be for utilization management decisions in lung cancer treatment at Sloan–Kettering in conjunction with health insurance company WellPoint. Watson’s business chief Manoj Saxena says that 90% of nurses in the field who use Watson now follow its guidance.

The Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit corporation headquartered in California that was incorporated in 1998 to oversee a number of Internet-related tasks previously performed directly on behalf of the U.S. Department of Defense, which created the Internet. ICANN manages the assignment of domain names and IP addresses. To date, much of its work is about making new generic top-level domains (e.g. .edu, .com, .gov, etc.).

Network neutrality is a principle that restricts Internet Service Providers (ISP) and governments from giving some internet traffic (email, web, peer-to-peer, BitTorrent, etc.) priority over others. On a completely neutral network, all traffic is treated equally. On non-neutral network, ISPs could charge for access to types of traffic, instead of for access to the internet in general. Some degree of traffic management is necessary on any network, but where to draw the line is at issue presently. Many believe net neutrality to be primarily important as a preservation of current freedoms.
Vinton Cerf, considered a ‘father of the Internet’ and co-inventor of the Internet Protocol, Tim Berners-Lee, creator of the Web, and many others have spoken out in favor of network neutrality. Opponents of net neutrality contend that broadband service providers have no plans to block content or degrade network performance. In spite of this claim, some Internet service providers have intentionally slowed peer-to-peer communications. Still other companies have acted in contrast to these assertions of hands-off behavior and have begun to discriminate against P2P, FTP and online games, instituting a cell-phone style billing system of overages, free-to-telecom ‘value added’ services,’ and bundling.

A black light is a lamp that emits electromagnetic radiation almost exclusively in the soft near ultraviolet range that is only partially visible. It is mainly seen by humans using the low-light receptors in the eye, which are sensitive to near ultraviolet. The low-light receptors however also have the distinctive feature that they are more accurate in the peripheral vision, this means black light will always look out of focus when looked at directly. In medicine, forensics, and some other scientific fields, such a light source is referred to as a Wood’s lamp (named for American physicist, Robert Williams Wood).
Black light sources have many uses. They may be employed for decorative and artistic lighting effects, for diagnostic and therapeutic uses in medicine, for the eradication of microorganisms, for the observation or detection of substances tagged with other substances that exhibit a fluorescent effect, for the curing of plastic resins and for attracting insects. Strong sources of long-wave ultraviolet light are used in tanning beds. Black light lamps are used for the detection of counterfeit money.

Wunderwaffe (‘wonder weapon’) and was a term assigned during World War II by the German propaganda ministry to a few revolutionary ‘superweapons.’ Most of these weapons however remained more or less feasible prototypes, or reached the combat theatre too late, and in too insignificant numbers (if at all) to have a military effect. A derisive abbreviation of the term emerged: Wuwa, pronounced ‘voo-vah.’
The ‘V’-weapons (including the V-2 rocket), which were developed earlier, and saw considerable deployment especially against Great Britain, trace back to the same pool of highly inventive armament concepts. Although the Wunderwaffen failed to meet their strategic objective of turning the tides of World War II in Nazi Germany’s favor at a time when the war was already strategically lost, they represented designs and prototypes that were extremely advanced for their time including some of the the earliest work on rockets, jets, night vision, orbital weapons, and ballistic missile submarines.

The Pale Blue Dot is a photograph of planet Earth taken in 1990 by Voyager 1 from a record distance, showing it against the vastness of space. By request of Carl Sagan, NASA commanded the Voyager 1 spacecraft, having completed its primary mission and now leaving the Solar System, to turn its camera around and to take a photograph of Earth across a great expanse of space. Subsequently, the title of the photograph was used by Sagan as the primary title of his 1994 book, ‘Pale Blue Dot: A Vision of the Human Future in Space.’

Tux is a penguin character and the official mascot of the Linux operating system originally created as an entry to a Linux logo competition. The concept of the Linux mascot being a penguin came from Linus Torvalds, the creator of Linux. Tux was created by Larry Ewing in 1996 after an initial suggestion made by Alan Cox and further refined by Linus Torvalds on the Linux kernel mailing list.
