Uniform Resource Identifier

In information technology, a Uniform Resource Identifier (URI) is a string of characters used to identify a resource. Such identification enables interaction with representations of the resource over a network, typically the World Wide Web, using specific protocols. Schemes specifying a concrete syntax and associated protocols define each URI. The most common form of URI is the Uniform Resource Locator (URL), frequently referred to informally as a web address. More rarely seen in usage is the Uniform Resource Name (URN), which was designed to complement URLs by providing a mechanism for the identification of resources in particular namespaces.

Relationships among URIs, URLs, and URNs

A Uniform Resource Name (URN) functions like a person's name, while a Uniform Resource Locator (URL) resembles that person's street address. In other words: the URN defines an item's identity, while the URL provides a method for finding it.

URLs

A URL is a URI that, in addition to identifying a web resource, specifies the means of acting upon or obtaining the representation of it, i.e. specifying both its primary access mechanism and network location. For example, the URL http://example.org/wiki/Main_Page refers to a resource identified as /wiki/Main_Page whose representation, in the form of HTML and related code, is obtainable via HyperText Transfer Protocol (http) from a network host whose domain name is example.org.

Channel 4

Channel 4 is a British public-service television broadcaster that began transmission on 2 November 1982. Although largely commercially self-funded, it is ultimately publicly owned; originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by Channel Four Television Corporation, a public body established in 1990, coming into operation in 1993. With the conversion of the Wenvoe transmitter group in Wales to digital on 31 March 2010, Channel 4 became a UK-wide TV channel for the first time.

The channel was established to provide a fourth television service to the United Kingdom in addition to the television licence-funded BBC's two services and the single commercial broadcasting network, ITV.

History

Conception

Before Channel 4 and S4C, Britain had three terrestrial television services: BBC1, BBC2, and ITV. The Broadcasting Act 1980 began the process of adding a fourth, and Channel 4, along with its Welsh counterpart, was formally created by an Act of Parliament in 1982. After some months of test broadcasts, it began scheduled transmissions on 2 November 1982.

List of Invader Zim characters

Invader Zim is an American animated television series created by Jhonen Vasquez and originally aired on Nickelodeon. The recurring cast includes long-term Nickelodeon voice actors Richard Steven Horvitz and Rodger Bumpass, with live-action television actors Kevin McDonald (The Kids in the Hall) and John de Lancie (Star Trek: The Next Generation). Vasquez voices parts in the show. The show was cancelled early in its run and some episodes were unfinished. The show ran for two seasons before its cancellation.

Main characters

Zim

Zim (voiced by Richard Steven Horvitz,Billy West in the pilot and Melissa Fahn as a smeet in "Parent Teacher Night") is an incompetent Irken invader who is foul-tempered, overzealous, impulsive, megalomaniac, and convinced of his own greatness. He dreams of regaining his leaders' trust by taking part in Operation Impending Doom II, so Zim is assigned to Earth, a planet which the Almighty Tallest believe has little to no chance of existing. However, against all odds, Zim makes it to Earth and establishes a base on a fake conquest mission. Because of his very small stature, Zim disguises himself as a human child using a hairpiece to cover his antennae and contact lenses to make his eyes look normal.

Tak (function)

In computer science, the Tak function is a recursive function, named after Ikuo Takeuchi (竹内郁雄). It is defined as follows:

This function is often used as a benchmark for languages with optimization for recursion.

tak() vs. tarai()

The original definition by Takeuchi was as follows:

tarai is short for tarai mawashi, "to pass around" in Japanese.

John McCarthy named this function tak() after Takeuchi.

However, in certain later references, the y somehow got turned into the z. This is a small, but significant difference because the original version benefits significantly by lazy evaluation. Though written in exactly the same manner as others, the Haskell code below runs much faster.

You can easily accelerate this function via memoization yet lazy evaluation still wins.

The best known way to optimize tarai is to use mutually recursive helper function as follows.

Here is an efficient implementation of tarai() in C:

Note the additional check for (x <= y) before z (the third argument) is evaluated, avoiding unnecessary recursive evaluation.

Tak (town)

Tak is a town (thesaban mueang) in north-west Thailand, capital of the Tak Province and the Tak district. As of 2005 the town had a population of 19,900 and an area of 7.27 km². It covers the tambon Rahaeng, Nong Luang, Chiang Ngoen, and Hua Diat. It is on the Ping River, 418 km north-north-west of Bangkok.

Geography

Tak is on the Ping River, which runs from north to south through the town. While the land to the east is fairly flat, the Tenasserim Hills and Dawna Range lie to the west.

Climate

Tak has a tropical savanna climate (Köppen climate classification Aw). Winters are dry and very warm. Temperatures rise until April, which is very hot with the average daily maximum at 38.5 °C (101.3 °F). The monsoon season runs from May through October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm.

Transportation

Route 105, through Mae Sot, forms one of two major transnational roads through the Tenasserim Hills to Burma. Route 1, also known as the Phahonyothin Road, passes through Tak. On the north side it leads to Lampang, Chiang Rai, and the border with Burma at Mae Sai. On the south side it leads to Kamphaeng Phet, Nakhon Sawan, and Bangkok. Route 12 leads east to Sukhothai, Phitsanulok, Chum Phae, Khon Kaen, Kalasin, and the border with Laos at Mukdahan.

List of starships in Stargate

This is a list of fictional starships in the Stargate universe depicted through a series of television shows and three feature-length movies.

Ancient starships

The Ancients are one of the most technologically advanced races in Stargate, and this is reflected in their starships. Duplicates of these ships are utilized by their nanite creations, the Asurans, as they also possess knowledge of Ancient technology.

Puddle Jumper

The Puddle Jumper or Jumper is a small spacecraft used extensively in the Stargate Atlantis series. Puddle Jumpers were created by the Ancients and most exist within the city built by the Ancients known as Atlantis. The Jumpers are used by the humans from Earth that traveled to Atlantis so that they can travel to other planets as well as navigate the planets once they arrive—both in the air and underwater. Jumpers are cylinder-shaped with two retractable engines (see picture at right), one on either side, so that they can fit through the Stargate device. The interior of the Jumper is divided in two parts: cockpit and aft; the bulkhead door between the two sections is airtight and can hold even against the pressure of deep ocean. Access to the Jumper is provided by a rear ramp-hatch. Puddle Jumpers are armed with drone weapons capable of destroying larger ships. Jumpers are also equipped with a cloaking device to evade enemies which renders the ship effectively invisible to both the eye and most sensors.
