Mutha's Day Out

Mutha's Day Out is an alternative metal band formed in November 1991 from the town of Batesville, Arkansas. The band consisted of: Mikal Moore (vocals), Brice Stephens (vocals), Chuck Schaaf (guitar), Jeff Morgan (bass), and Rodney Moffitt (drums). They released one album, My Soul is Wet, in 1993 for Chrysalis Records before breaking up.

In early 2012, it was announced on Mikal's Facebook account that a reunion is in the works. However, there have been no further updates since February 2012.

Biography

Early days (1991-1992)

Mikal Moore (born Mikal Morehead) and Randy Cross conceived Mutha's Day Out through influence of the Beastie Boys, with three vocalists (Mikal, Brice Stephens, and Randy). The name was thought up by Brice and came from a daycare center in Batesville that kids could go to for pre-school in Methodist churches. Jeff Morgan had just been kicked out of a band he and Chuck Schaaf were in when Mikal asked him to be in a band that would sound like "Faith No More, Beastie Boys, and Ozzy Osbourne." The band was rounded out by Rodney Moffitt, who played drums, and Lance Branstetter, who played guitar, with Chuck serving as his guitar tech. When the band first came together, Lance was 21 years old, Mikal was 20 years old, Brice was 18 years old, Chuck was 17 years old, Rodney was 17 years old, and Jeff was 15 years old.

List of HTTP status codes

The following is a list of Hypertext Transfer Protocol (HTTP) response status codes. This includes codes from IETF internet standards as well as other IETF RFCs, other specifications and some additional commonly used codes. The first digit of the status code specifies one of five classes of response; the bare minimum for an HTTP client is that it recognises these five classes. The phrases used are the standard examples, but any human-readable alternative can be provided. Unless otherwise stated, the status code is part of the HTTP/1.1 standard (RFC 7231).

The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes.

Microsoft IIS sometimes uses additional decimal sub-codes to provide more specific information, but these are not listed here.

1xx Informational

Request received, continuing process.

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions.

Slug (railroad)

A railroad slug is an accessory to a diesel-electric locomotive. It has trucks with traction motors but, unlike a B unit, is unable to move about under its own power, as it does not contain a prime mover to produce electricity, nor is there a cab for an operator. Instead, it is connected to a locomotive, called the mother, which provides the needed electrical power to operate the traction motors, and the motor controls.

Basic principles

A slug is used to increase adhesive weight, allowing full power to be applied at a lower speed, thus allowing a higher maximum tractive effort. They are often used in low-speed operations such as switching operations in yards. At low speeds, a diesel-electric locomotive prime mover is capable of producing more electricity than its traction motors can use effectively. Extra power would simply cause the wheels to slip and possibly overheat the traction motors. A slug increases the number of traction motors available to the locomotive, increasing both the pulling and braking power. In addition the load on each traction motor is reduced, which helps prevent overheating from excess current. Slugs typically carry ballast to increase their weight and improve traction. Large blocks of concrete are frequently used for this purpose, substituting for the weight of the now-absent prime mover.

Slug (band)

Slug was a noise rock group that formed in Los Angeles in 1988 by DJs from Loyola Marymount University campus radio station KXLU. Originally formed as an experimental noise collage trio utilizing metal percussion, feedback and primitive sound loops created via gouged children's and sound effect records, they subsequently added traditional instrumentation (2 basses, 2 guitars, drums, vocals) to the mix.

Slug self-released their first single on their own label Magnatone Recordings. After the release of their first album Swingers, guitarist Rich Alvarez left to pursue his own band Jackknife, and was replaced by Collin Rae, formerly of 4AD artist Ultra Vivid Scene.

Before the recording of their third album The 3 Man Themes, bassist Michael B.© left to be replaced by David Scott Stone.

Slug disbanded in 1996. Stone would go on to work with The Melvins, LCD Soundsystem and other groups. Bassist Damian Romero continued his side noise/ambient project under the name Speculum Fight. Guitarist Todd Williams relocated to New York City to work as a film editor. Drummer Tomás Palermo moved to the San Francisco Bay area as a freelance writer on reggae for URB magazine and other publications. Guitarist Collin Rae moved to the Bay Area as well, performing in other groups as well as continuing his work as a professional photographer.

Semantic URL

Semantic URLs, also sometimes referred to as clean URLs, RESTful URLs, user-friendly URLs, or search engine-friendly URLs, are Uniform Resource Locators (URLs) intended to improve the usability and accessibility of a website or web service by being immediately and intuitively meaningful to non-expert users. Such URL schemes tend to reflect the conceptual structure of a collection of information and decouple the user interface from a server's internal representation of information. Other reasons for using clean URLs include search engine optimization (SEO), conforming to the representational state transfer (REST) style of software architecture, and ensuring that individual web resources remain consistently at the same URL. This makes the World Wide Web a more stable and useful system, and allows more durable and reliable bookmarking of web resources.

Semantic URLs also do not contain implementation details of the underlying web application. This carries the benefit of reducing the difficulty of changing the implementation of the resource at a later date. For example, many non-semantic URLs include the filename of a server-side script, such as example.php, example.asp or cgi-bin. If the underlying implementation of a resource is changed, such URLs would need to change along with it. Likewise, when URLs are non-semantic, if the site database is moved or restructured it has the potential to cause broken links, both internally and from external sites, the latter of which can lead to removal from search engine listings. The use of semantic URLs presents a consistent location for resources to user-agents regardless of internal structure. A further potential benefit to the use of semantic URLs is that the concealment of internal server or application information can improve the security of a system.
