The EURion constellation (also known as Omron rings or doughnuts) is a pattern of symbols incorporated into a number of banknote designs worldwide since about 1996. It is added to help imaging 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 colour photocopiers. According to research from 2004, the EURion constellation is used for colour photocopiers but probably not used in computer software. It has been reported that Adobe Photoshop will not allow editing of an image of a banknote, but in some versions this is believed to be due to a different, unknown digital watermark rather than the EURion constellation.

The Casio F-91W is a digital watch manufactured by Japanese electronics company Casio. Introduced in 1989, it is popular for its low price and long battery life. Annual production is 3 million units per year.

Potoooooooo or variations of Pot-8-Os (1773 – November 1800) was an 18th-century thoroughbred racehorse who won over 30 races and defeated some of the greatest racehorses of the time. He went on to be a sire. He is now best known for the unusual spelling of his name, pronounced 'Potatoes'.

Sousveillance ( soo-VAY-lənss) is the recording of an activity by a participant in the activity, typically by way of small wearable or portable personal technologies. The term "sousveillance", coined by Steve Mann, stems from the contrasting French words sur, meaning "above", and sous, meaning "below", i.e. "surveillance" denotes the "eye-in-the-sky" watching from above, whereas "sousveillance" denotes bringing the camera or other means of observation down to human level, either physically (mounting cameras on people rather than on buildings), or hierarchically (ordinary people doing the watching, rather than higher authorities or architectures doing the watching).

While surveillance and sousveillance both generally refer to visual monitoring, the terms also denote other forms of monitoring such as audio surveillance or sousveillance. In the audio sense (e.g. recording of phone conversations), sousveillance is referred to as "one party consent".

Undersight (inverse oversight) is sousveillance at high-level, e.g. "citizen undersight" being reciprocal to a congressional oversight committee or the like.

Inverse surveillance is a subset of sousveillance with a particular emphasis on the "watchful vigilance from underneath" and a form of surveillance inquiry or legal protection involving the recording, monitoring, study, or analysis of surveillance systems, proponents of surveillance, and possibly also recordings of authority figures and their actions. Inverse surveillance is typically an activity undertaken by those who are generally the subject of surveillance, and may thus be thought of as a form of an ethnography or ethnomethodology study (i.e. an analysis of the surveilled from the perspective of a participant in a society under surveillance).

Sousveillance typically involves community-based recording from first person perspectives, without necessarily involving any specific political agenda, whereas inverse-surveillance is a form of sousveillance that is typically directed at, or used to collect data to analyze or study, surveillance or its proponents (e.g., the actions of police or protestors at a protest rally).

Sousveillance is not necessarily countersurveillance; i.e. sousveillance can be used to "counter" the forces of surveillance, or it can also be used together with surveillance to create a more complete "veillance" ("Surveillance is a half-truth without sousveillance"). The question of "Who watches the watchers" is dealt with more properly under the topic of metaveillance (the veillance of veillance) than sousveillance.

Daniel "Dan" William Dobberpuhl (March 25, 1945 – October 26, 2019) was an electrical engineer in the United States who led several teams of microprocessor designers.

HAKMEM, alternatively known as AI Memo 239, is a February 1972 "memo" (technical report) of the MIT AI Lab containing a wide variety of hacks, including useful and clever algorithms for mathematical computation, some number theory and schematic diagrams for hardware — in Guy L. Steele's words, "a bizarre and eclectic potpourri of technical trivia". Contributors included about two dozen members and associates of the AI Lab. The title of the report is short for "hacks memo", abbreviated to six upper case characters that would fit in a single PDP-10 machine word (using a six-bit character set).

The CueCat, styled :CueCat with a leading colon, is a cat-shaped handheld barcode reader that was given away free to Internet users starting in 2000 by the now-defunct Digital Convergence Corporation. The CueCat was named CUE for the unique bar code which the device scanned and CAT as a play on "Keystroke Automation Technology" and it enabled a user to open a link to an Internet URL by scanning a barcode — called a "cue" by Digital Convergence — appearing in an article or catalog or on some other printed matter. In this way, a user could be directed to a web page containing related information without having to enter a URL. The company asserted that the ability of the device to direct users to a specific URL, rather than a domain name, was valuable. In addition, television broadcasters could use an audio tone in programs or commercials that, if a TV was connected to a computer via an audio cable, acted as a web address shortcut.

The CueCat connected to computers using the PS/2 keyboard port and USB, and communicated to desktop "CRQ" software running on Windows 32-bit and Mac OS 9 operating systems. Users of this software were required to register with their ZIP code, gender, and email address. This registration process enabled the device to deliver relevant content to a single or multiple users in a household.

By year-end 2001, Codes could no longer be generated for the device or scanned with the device. However, third-party software can decode the lightweight encryption in the device.

An article about or described by any of the following can be safely assumed to fit into the set of unnecessary articles:

1. You, your family, or the organization you work for.
2. Your band, which has only sold 47 copies of its one album. Even if you think it will sell 48. Or maybe 49! Or, if you get really lucky, you can pay off the record store owner so that he may buy one and your sales will have gone up to fifty!!! Keep dreamin', brotha.
3. Your imaginary friend or your imaginary friends that don't even exist.
4. The religion, language or even country that you made up with your friends in school one day.
5. The street you live on, unless it is on a Monopoly board. But since it is highly unlikely that you live on a Monopoly game board, we suggest that you not even try.
6. Any one of the 16 distinct regions in the Pokémon video game series or lieking mudkipz, or hering dat someon lieks mudkipz. Remember, not everyone is a Pokémon fanatic.
7. A stunt or trick only you have ever attempted, probably unsuccessfully.
8. Any movie you made yourself which has never been seen by more people at one time than can fit in your basement. Even if you have a really big basement.
9. Individual songs that have never been released as a single nor seen radio play, unless they're twenty minutes long or have led to a phone number becoming unusable or even have questioned the essence of music itself.
10. "(Anything) in popular culture." Anything at all.
11. Likewise "Hysterical Realism in the Works of (insert neither hysterical nor realistic author here)".
12. Your dormitory, university residence, or any suite therein.
13. Stuff nobody but that guy who changes his Spock ears more often than his underpants cares about, or the equivalent thereto. For example, a song about a custom map of a video game, unless you are famous and the song managed to release as a single.
14. Anything about which you cannot be buggered to write one complete sent
15. Subjects that cannot be studied, or the knowledge of which amounts only to the fact that it pertains to another topic. A favourite line from a movie or catchy lyric, a potent phrase used in argument, juicy facts of interest to fans, a punch-line or zinger; these are all very interesting, but usually all that can be informatively written about topic "X" is: "X is a _______ found in _______."
16. Just about everything listed on Wikipedia:Millionth topic pool.
17. For that matter, Wikipedia:Millionth topic pool.
18. Anything about your cat or dog and how cute it is (or your hamster, degu, or chinchilla).
19. Exploding Whales, or indeed Exploding Wales, or even Exploding Wales. Or blowing up any other animals, for example, exploding mice, or even exploding Velociraptor, for that matter. Most things that implode are pretty much off the list too, with a few exceptions.

21. An article about another article, written after the use of aforementioned substances.
22. A fork of an existing article for the sole purpose of adding some humor.
23. The weather in London. Not even a redirect. (Wowee).
24. Your guild in World of Warcraft or similar time wasters. Just because you have no life a personally fascinating hobby doesn't mean you get to tell the world about it. And don't write about this guy in your guild who wiped your raid, either.
25. Something you just saw on YouTube and, possibly, laughed at.
26. Something you just put on YouTube.
27. An article that haz badly grammar and/or speelling. Including, bad punctuation!!

32. Anything about your cat named Bubba or your dog named Max. No one cares. Trust us.
33. Your nomination for the Noble (or even Nobel) Peace Prize.
34. Anything about how you were abducted by aliens.

36. An article on the person that knocked on your door while you was writing the article about your dream last night, causing you to forget about the dream (but I’ll be honest, I feel for you).

The iAPX 432 (Intel Advanced Performance Architecture) is a discontinued computer architecture introduced in 1981. It was Intel's first 32-bit processor design. The main processor of the architecture, the general data processor, is implemented as a set of two separate integrated circuits, due to technical limitations at the time. Although some early 8086, 80186 and 80286-based systems and manuals also used the iAPX prefix for marketing reasons, the iAPX 432 and the 8086 processor lines are completely separate designs with completely different instruction sets.

The project started in 1975 as the 8800 (after the 8008 and the 8080) and was intended to be Intel's major design for the 1980s. Unlike the 8086, which was designed the following year as a successor to the 8080, the iAPX 432 was a radical departure from Intel's previous designs meant for a different market niche, and completely unrelated to the 8080 or x86 product lines.

The iAPX 432 project is considered a commercial failure for Intel, and was discontinued in 1986.

The Smart File System (SFS) is a journaling filesystem used on Amiga computers and AmigaOS-derived operating systems (though some support also exists for IBM PC compatibles). It is designed for performance, scalability and integrity, offering improvements over standard Amiga filesystems as well as some special or unique features.
