Number sign

Number sign is a name for the symbol #, which is used for a variety of purposes, including (mainly in Canada and the United States) the designation of a number (for example, "#1" stands for "number one"). On many social media platforms, it is used to declare a searchable metadata tag called a hashtag.

The term number sign is most commonly used when the symbol is used before a number. In the United States and Canada, it is sometimes known as the pound sign (particularly in the context of its use on telephone keypads), and has been traditionally used in the food industry as an abbreviation for pounds avoirdupois. Outside of North America the symbol is called hash and the corresponding telephone key is called the "hash key", and the term "pound sign" usually describes the British currency symbol "£". The symbol is defined in Unicode as U+0023 # NUMBER SIGN (HTML # · as in ASCII).

The symbol may be confused with the musical symbol called sharp (♯). In both symbols, there are two pairs of parallel lines. The main difference is that the number sign has two horizontal strokes while the sharp sign has two slanted parallel lines which must rise from left to right, in order to avoid being obscured by the horizontal musical staff lines. Although the signs are strictly speaking different, one of the names for the telephone number sign key in French is dièse (sharp sign), and the name of the programming language C sharp is usually rendered with a hash symbol rather than the technically correct sharp sign.

Spider (portal)

Strathclyde Personal Interactive Development and Educational Resource (SPIDER) is a virtual learning environment used by the University of Strathclyde to provide an online platform for class material, support and more.

History

SPIDER began in 1998 as a web project to convert a single course module into an interactive web environment. Originally in 1998 SPIDER was a "static" website and was coded in HTML. This type of coding became a flaw to development as hand scripting HTML became very time consuming.

Development Timeline

The development of SPIDER is documented from its creation in 1998. The following bullet points give the main development from previous versions.

Spider (DC Comics)

"Alias the Spider" is a comic-book feature from the 1930s and 1940s Golden Age of Comic Books that appeared in Quality Comics' Crack Comics for nearly three years, starting with issue #1 in 1940. He was created by writer-artist Paul Gustavson.

The original, Golden Age version of the character is in public domain, but the rights to all subsequent versions are owned by DC Comics.

Publication history

Only one adventure of the Spider has ever been reprinted by DC Comics, which acquired the Quality Comics stable of characters when that company went out of business in 1956: The story from Crack Comics #25, in Detective Comics #441.

The Spider later made sporadic cameo appearances in All-Star Squadron and The Young All-Stars. As a Quality Comics character, he was one of the heroes who went with Uncle Sam to protect Earth-X during World War II, becoming part of the Freedom Fighters. This was the fulfillment of a storyline that began in Justice League of America #107-108, which introduced most of Quality Comics' characters to the DC Universe. Previously only Plastic Man and Blackhawk had been used.

Spider (pulp fiction)

The Spider is an American pulp-magazine hero of the 1930s and 1940s.

Background

The Spider was created in 1933 by Harry Steeger at Popular Publications as direct competition to Street and Smith Publications' vigilante hero, the Shadow. Though similar, The Spider was millionaire playboy Richard Wentworth, who had served as a Major in World War I, and was living in New York City unaffected by the financial deprivations of the Great Depression. The ninth pulp has him as the last surviving member of a rich family.

Wentworth was easily identified as The Spider by his enemies in a number of earlier novels and was arrested by the police but quickly escaped, adopting a disguise and associated alias Tito Caliepi, donning make-up, a wig of lank hair, a black cape, and slouch hat. Later in the pulp series, vampire-like makeup appeared and then a face mask with grizzled hair; a hunchback was then added to terrorize the criminal underworld with The Spider's brand of violent vigilante justice. (Actor and comedian Harold Lloyd previously had used a similar mask, lank hair wig, and hunchback in the comedy film Dr. Jack (1922)). Caliepi sometimes begged, utilizing Wentworth's talent with a violin.
