The Streisand effect is a social phenomenon that occurs when an attempt to hide, remove, or censor information has the unintended consequence of further publicizing that information, often via the Internet. It is named after American entertainer Barbra Streisand, whose attempt to suppress photographs of her residence in Malibu, California inadvertently drew further attention to it in 2003.

Attempts to suppress information are often made through cease-and-desist letters, but instead of being suppressed, the information receives extensive publicity, as well as media extensions such as videos and spoof songs, which can be mirrored on the Internet or distributed on file-sharing networks.

The Streisand effect is an example of psychological reactance, wherein once people are aware that some information is being kept from them, they are significantly more motivated to access and spread that information.

Lake Agassiz was a very large glacial lake in central North America. Fed by glacial meltwater at the end of the last glacial period, its area was larger than all of the modern Great Lakes combined though its mean depth was not as great as that of many major lakes today.

First postulated in 1823 by William H. Keating, it was named by Warren Upham in 1879 after Louis Agassiz, when Upham recognized that the lake was formed by glacial action.

ILOVEYOU, sometimes referred to as Love Bug or Love Letter for you, is a computer worm that infected over ten million Windows personal computers on and after 4 May 2000 when it started spreading as an email message with the subject line "ILOVEYOU" and the attachment "LOVE-LETTER-FOR-YOU.txt.vbs". The latter file extension ('vbs', a type of interpreted file) was most often hidden by default on Windows computers of the time (as it is an extension for a file type that is known by Windows), leading unwitting users to think it was a normal text file. Opening the attachment activates the Visual Basic script. The worm inflicts damage on the local machine, overwriting random types of files (including Office files, image files, and audio files; however after overwriting MP3 files the virus hides the file), and sends a copy of itself to all addresses in the Windows Address Book used by Microsoft Outlook. This made it spread much faster than any other previous email worm.

🔗 Biography 🔗 Psychology 🔗 Biography/science and academia

Edwin Ray Guthrie (; January 9, 1886 in Lincoln, Nebraska – April 23, 1959 in Seattle, Washington) was a behavioral psychologist. He first worked as a mathematics teacher, and philosopher, but switched to psychology when he was 33. He spent most of his career at the University of Washington, where he became full professor and then emeritus professor in psychology.

Guthrie is best known for his theory that all learning was based on a stimulus–response association. This was variously described as one trial theory, non-reinforcement, and contiguity learning. The theory was:

"A combination of stimuli which has accompanied a movement will on its recurrence tend to be followed by that movement".

One word that his coworkers and students used to describe Guthrie and his theories was "simple", and perhaps he did prefer to use simple terms to illustrate complex ideas. However, "It is undoubtedly true that many reviews of Guthrie in the literature have mistaken incompleteness for simplicity".

His simple nature carried into his teachings where he took great pride in working with and teaching students.

🔗 Cryptography 🔗 Cryptography/Computer science

In cryptography, the dining cryptographers problem studies how to perform a secure multi-party computation of the boolean-OR function. David Chaum first proposed this problem in the early 1980s and used it as an illustrative example to show that it was possible to send anonymous messages with unconditional sender and recipient untraceability. Anonymous communication networks based on this problem are often referred to as DC-nets (where DC stands for "dining cryptographers").

Despite the word dining, the dining cryptographers problem is unrelated to the dining philosophers problem.

🔗 Biography 🔗 Architecture 🔗 Biography/science and academia 🔗 Urban studies and planning 🔗 University of California

Christopher Wolfgang Alexander (born 4 October 1936 in Vienna, Austria) is a widely influential British-American architect and design theorist, and currently emeritus professor at the University of California, Berkeley. His theories about the nature of human-centered design have affected fields beyond architecture, including urban design, software, sociology and others. Alexander has designed and personally built over 100 buildings, both as an architect and a general contractor.

In software, Alexander is regarded as the father of the pattern language movement. The first wiki—the technology behind Wikipedia—led directly from Alexander's work, according to its creator, Ward Cunningham. Alexander's work has also influenced the development of agile software development.

In architecture, Alexander's work is used by a number of different contemporary architectural communities of practice, including the New Urbanist movement, to help people to reclaim control over their own built environment. However, Alexander is controversial among some mainstream architects and critics, in part because his work is often harshly critical of much of contemporary architectural theory and practice.

Alexander is known for many books on the design and building process, including Notes on the Synthesis of Form, A City is Not a Tree (first published as a paper and re-published in book form in 2015), The Timeless Way of Building, A New Theory of Urban Design, and The Oregon Experiment. More recently he published the four-volume The Nature of Order: An Essay on the Art of Building and the Nature of the Universe, about his newer theories of "morphogenetic" processes, and The Battle for the Life and Beauty of the Earth, about the implementation of his theories in a large building project in Japan. All his works are developed or accumulated from his previous works, so his works should be read as a whole rather than fragmented pieces. His life's work or the best of his works is The Nature of Order on which he spent about 30 years, and the very first version of The Nature of Order was done in 1981, one year before this famous debate with Peter Eisenman in Harvard.

Alexander is perhaps best known for his 1977 book A Pattern Language, a perennial seller some four decades after publication. Reasoning that users are more sensitive to their needs than any architect could be, he produced and validated (in collaboration with his students Sara Ishikawa, Murray Silverstein, Max Jacobson, Ingrid King, and Shlomo Angel) a "pattern language" to empower anyone to design and build at any scale.

Alan L. Hart (born Alberta Lucille Hart, October 4, 1890 – July 1, 1962) was an American physician, radiologist, tuberculosis researcher, writer and novelist. He was in 1917–18 one of the first trans men to undergo hysterectomy in the United States, and lived the rest of his life as a man. He pioneered the use of x-ray photography in tuberculosis detection, and helped implement TB screening programs that saved thousands of lives.

🔗 Psychology

The behavioral immune system is a phrase coined by the psychological scientist Mark Schaller to refer to a suite of psychological mechanisms that allow individual organisms to detect the potential presence of disease-causing parasites in their immediate environment, and to engage in behaviors that prevent contact with those objects and individuals.

These mechanisms include sensory processes through which cues connoting the presence of parasitic infections are perceived (e.g., the smell of a foul odor, the sight of pox or pustules), as well as stimulus–response systems through which these sensory cues trigger a cascade of aversive affective, cognitive, and behavioral reactions (e.g., arousal of disgust, automatic activation of cognitions that connote the threat of disease, behavioral avoidance).

The existence of a behavioral immune system has been documented across many animal species, including humans. It is theorized that the mechanisms that comprise the behavioral immune system evolved as a crude first line of defense against disease-causing pathogens.

The Joy programming language in computer science is a purely functional programming language that was produced by Manfred von Thun of La Trobe University in Melbourne, Australia. Joy is based on composition of functions rather than lambda calculus. It has turned out to have many similarities to Forth, due not to design but to a sort of parallel evolution and convergence. It was also inspired by the function-level programming style of John Backus's FP.

🔗 Computing

The Owner-Free File System (OFF System, or OFF for short) is a peer-to-peer distributed file system in which all shared files are represented by randomized multi-used data blocks. Instead of anonymizing the network, the data blocks are anonymized and therefore, only data garbage is ever exchanged and stored and no forwarding via intermediate nodes is required. OFF claims to have been created with the expressed intention "to cut off some gangrene-infested bits of the copyright industry."
