Dervish

A dervish or darvesh (from Persian: درویش‎‎, Darvīsh via Turkish,Somali: Daraawiish, Arabic: درويش‎, Darwīš) is someone treading a Sufi Muslim ascetic path or "Tariqah", known for their extreme poverty and austerity. His focus is on the universal values of love and service, deserting the illusions of ego to reach God. In most Sufi orders, a dervish is known to practice dhikr through physical exertions or religious practices to attain the ecstatic trance to reach Allah. Their most common practice is Sema which is associated with Rumi.

Dervish are an Irish traditional music group from County Sligo, Ireland who have been described by BBC Radio 3 as "an icon of Irish music". They were formed in 1989 by Liam Kelly, Shane Mitchell, Martin McGinley, Brian McDonagh, and Michael Holmes and have been fronted by singer Cathy Jordan since 1991. They represented Ireland in the final of the Eurovision Song Contest 2007, singing a song written by John Waters and Tommy Moran, finishing in last place.

History

The band was originally called The Boys of Sligo; an album under this title, with Martin McGinley on fiddle but no vocals, was released by Sound records (SUNCD 1).

In 1991 the band were joined by Roscommon-born singer Cathy Jordan and fiddle player Shane McAleer. Dervish’s first album, "Harmony Hill", was released in 1993. In 1994 their second album, "Playing with Fire", was released. In 1996 Dervish released "At the End of the Day".

Their fourth album, "Live in Palma", was recorded in front of a live audience in 1997. In 1998 McAleer left the band and was replaced by Sligo musician Séamus O'Dowd and fiddle player Tom Morrow. Dervish's fifth album, "Midsummer's Night", was released in 1999. In 2001 Dervish released "Decade", a compilation of tracks from their first five albums. In 2003 they released "Spirit", followed by "A Healing Heart" in 2006.

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.
