Cipher

In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, 'cipher' is synonymous with 'code', as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography.

Codes generally substitute different length strings of characters in the output, while ciphers generally substitute the same number of characters as are input. There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that were input.

Codes operated by substituting according to a large codebook which linked a random string of characters or numbers to a word or phrase. For example, "UQJHSE" could be the code for "Proceed to the following coordinates." When using a cipher the original information is known as plaintext, and the encrypted form as ciphertext. The ciphertext message contains all the information of the plaintext message, but is not in a format readable by a human or computer without the proper mechanism to decrypt it.

Cipher (newuniversal)

Cipher (Jennifer Swann) is a fictional character appearing in American comic books published by Marvel Comics. The character appears in the newuniversal imprint of Marvel Comics, and is one of the four initial superhumans created by the White Event in 2006 (the others being Justice, Nightmask, and Star Brand). newuniversal, designated Earth-555 in the Marvel Comics multiverse, is a re-imagining of the New Universe imprint from the late 1980s. The name Cipher actually refers to two things: a powerful extra-dimensional glyph (tattoo) that confers superhuman powers on a sentient being, and the name of the being that wields the glyph. Cipher is a new superhuman created by Warren Ellis and Salvador Larroca who were inspired by the original Spitfire and the nature of the Star Brand itself (as an extra-dimensional tool of near-unlimited power), combined with strong conceptual ties to Iron Man.

Fictional character biography

Project Spitfire

Essentially nothing is known about Dr. Jennifer Swann’s early life, or where she earned her doctorate. Sometime in the late 1990s or early 2000s she was hired by the NSA to work on Project Spitfire, taking her father’s previous position there. Jennifer continues the work her father, Dr. Joseph Swann, began in 1959 on the H.E.X. (Human Enhancement eXperimental) initiative, an armored exoskeleton that is intended to enable its wearer to combat superhumans with a wide variety of weapons. The original suit was created by Anthony Stark in 1959 who became Cipher in the "The Fireworks" event in 1955, and is an alternate version of Tony Stark (Iron Man) from the mainstream Marvel Universe. Prior to the events in newuniversal #1, neither Jennifer nor her father were able to perfect the design, both suffering broken bones during testing.

Regret

Regret is a negative conscious and emotional reaction to personal past acts and behaviors. Regret is often expressed by the term "sorry" whereas "I'm sorry" can express both regret and sympathy. Regret is often a feeling of sadness, shame, embarrassment, depression, annoyance, or guilt, after one acts in a manner and later wishes not to have done so. Regret is distinct from guilt, which is a deeply emotional form of regret — one which may be difficult to comprehend in an objective or conceptual way. In this regard, the concept of regret is subordinate to guilt in terms of its emotional intensity. By comparison, shame typically refers to the social (rather than personal) aspect of guilt or (in minor context) regret as imposed by the society or culture (enforcement of ethics, morality), which has substantial bearing in matters of (personal and social) honor.

It is also distinct from remorse, which is a more direct and emotional form of regret over a past action that is considered by society to be hurtful, shameful, or violent. Unlike regret, it includes a strong element of desire for apology to others rather than an internal reflection on one's actions, and may be expressed (sincerely or not) in order to reduce the punishment one receives.

Regrets (James Brown song)

"Regrets" is a song by Barbara Wyrick. Originally written for Marie Osmond, it was instead recorded by James Brown. Released as a single in 1980, it reached #63 on the R&B chart. It also appeared on the album People. Writing in The Village Voice, Thulani Davis described it as "sentimental, nice enough but not at all compelling."

List of Planetes episodes

This is a list of episodes of the Japanese animated TV series Planetes (プラネテス, Puranetesu, Ancient Greek: πλάνητες "Wanderers") It began airing its 26 episode run on NHK BS-2 on October 4, 2003 and ended on February 23, 2004. Produced and animated by Sunrise, it was directed by Gorō Taniguchi and scripted by Ichirō Ōkouchi (both of whom would later reunite in 2006 to work on the Sunrise original production Code Geass). The anime began development and production before the end of the manga serialization. In the beginning and middle of the series, the writing and production staff only had the first three volumes of the manga as source. In order to fill the entire 26 episode run of the anime, new characters, new settings and new relationships between characters were made in order to increase dramatic tension, reinforce themes introduced in the manga, and introduce new themes that were compatible with the manga. While the manga deals more with existential themes, and humanity's relationship with space, the anime further expands the political elements of the story.
