RL (complexity)

Randomized Logarithmic-space (RL), sometimes called RLP (Randomized Logarithmic-space Polynomial-time), is the complexity class of computational complexity theory problems solvable in logarithmic space and polynomial time with probabilistic Turing machines with one-sided error. It is named in analogy with RP, which is similar but has no logarithmic space restriction.

The probabilistic Turing machines in the definition of RL never accept incorrectly but are allowed to reject incorrectly less than 1/3 of the time; this is called one-sided error. The constant 1/3 is arbitrary; any x with 0 < x < 1 would suffice. This error can be made 2^−p(x) times smaller for any polynomial p(x) without using more than polynomial time or logarithmic space by running the algorithm repeatedly.

Sometimes the name RL is reserved for the class of problems solvable by logarithmic-space probabilistic machines in unbounded time. However, this class can be shown to be equal to NL using a probabilistic counter, and so is usually referred to as NL instead; this also shows that RL is contained in NL. RL is contained in BPL, which is similar but allows two-sided error (incorrect accepts). RL contains L, the problems solvable by deterministic Turing machines in log space, since its definition is just more general.

Power!

Power! (known as Critical Mass in Europe) is a computer game developed by Simon Francis in 1985 for the Amstrad CPC, Commodore 64 and ZX Spectrum.

Plot

The player operates a rocket-powered hovercraft whose mission is to destroy an enemy transfer beam that is protected not only by long-distance enemy raiders and mines, but also molecular disorientation that sucks the energy from the player's attack craft.

Gameplay

The player may control the hovercraft in either a normal joystick operational mode or with vectored movement. When the player pushes forward on the joystick, the hovercraft accelerates, and when pulling back on the joystick, speed decreases.

Reception

In 1988, Dragon reviewed Power!, and gave the game 4 out of 5 stars.

PoweredUSB

PoweredUSB, also known as Retail USB, USB PlusPower, and USB +Power, is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter. It is mostly used in point-of-sale equipment, such as receipt printers and barcode readers.

History

PoweredUSB, as a proprietary variant of USB, was developed and proposed by IBM, Berg (now FCI), NCR and Microsoft between 1998 and 1999, with the last revision (0.8g) issued in 2004. The specification is not endorsed by the USB Implementers Forum (USB-IF). IBM, who owns patents to PoweredUSB, charges a licensing fee for its use.

PoweredUSB was licensed by Hewlett-Packard, Cyberdata, Fujitsu, Wincor and others.

Implementation

PoweredUSB uses a more complex connector than standard USB, maintaining the standard USB 1.x/2.0 interface for data communications and adding a second connector for power. Physically, it is essentially two connectors stacked such that the bottom connector accepts a standard USB plug and the top connector takes a power plug.

Power (2014 Telugu film)

Power is a 2014 Telugu action comedy film written and directed by K. S. Ravindra and produced by Rockline Venkatesh under the banner Rockline Entertainments, both marking their debut in Telugu cinema. It features Ravi Teja playing a dual role with Hansika Motwani and Regina Cassandra playing the female lead roles. S. Thaman composed the music while Gautham Raju edited the film. Arthur A. Wilson and Jayanan Vincent handled the film's cinematography. The film revolves around two similar looking people, Baldev Sahay - a corrupt ACP in Kolkata and Tirupathi - a person aspiring to become a police officer in Hyderabad. The home minister of Kolkata recruits Tirupathi to play as Baldev to catch a gangster rescued by Baldev. Rest of the story is all about why Baldev became a corrupt cop and how Tirupathi executed the unfinished mission of Baldev.

Production began on 11 December 2013. The film's talkie part was shot in Hyderabad, Bangalore, Kolkata, Chennai and Bangkok while two songs were shot in Bulgaria marking it the first Telugu film to be shot there. Principal photography ended on 14 August 2014. The film released on 12 September 2014 to positive reviews from critics and was a commercial success.

Native (band)

Native is a French R&B band composed of two sisters, Laura Mayne (born 20 January 1968 in Villemomble, Seine-Saint-Denis) and Chris Mayne (born 12 January 1970 in Villemomble). They began their singing career as backup singers with Niagara and Gérald De Palmas. They achieved their first success in 1994 with their single "Si la vie demande ça", a top ten hit in France.

In 1994, they won a Victoires de la musique award for most promising group of the year. They featured on the track, Who The F*** Is This on the album Bubba Sparxxx & The Muddkatz - New South: The Album B4 The Album Mixtape (2003).

After the group split, Laura Mayne released in 2002 her first solo album under the name Native, entitled Laura Mayne-Kerbrat.

In 2003, Chris Mayne formed the band West Isle with Éric Daniel, former member of Sweetness group. They released the album Ailleurs in 2006.

Albums

Native (album)

Native is the third studio album by American pop rock band OneRepublic. It was released on March 22, 2013 in Germany and Ireland, March 25 worldwide except North America, and March 26 in North America. The album was originally planned to be released at the end of 2012 with the lead single being "Feel Again", which was released on August 27, 2012. However, due to the album not being completed at the time, it was pushed back to early 2013. "Feel Again" was later branded as a promotional single, and on January 8, 2013, "If I Lose Myself" was released as the lead single for the album.

The most successful single was the third single "Counting Stars", which peaked at number two on the Billboard Hot 100, becoming their highest-charting hit since "Apologize" also peaked there in 2007. It has also become their biggest hit in the United Kingdom—it topped the charts there for two non-consecutive weeks—and has charted within the top ten in nine countries, including top five placements in Australia, Germany, Ireland and New Zealand. The album's fourth single, "Something I Need", has since been certified 3× Platinum in Australia and Gold in New Zealand, peaking in the top 5 in both countries. Fifth single "Love Runs Out" charted in the top 5 in thirteen countries, including the United Kingdom, whilst the sixth and final single "I Lived" was a minor success.
