Quadra

Quadra may refer to:

Macintosh Quadra 650

The Macintosh Quadra 650 and the Macintosh Centris 650 are two closely related personal computers that are a part of Apple Computer's Quadra and Centris series of Macintosh computers, respectively. When the Centris 650 was introduced in February 1993 alongside the smaller Centris 610, it was intended as the start of the new midrange Centris line of computers, a niche formerly occupied by the Quadra 700 which was discontinued. However, that proved confusing, and the Centris 650 was renamed to Quadra 650 in October 1993, with the CPU upgraded from a 25 MHz to 33 MHz. The Quadra 650 was discontinued without a direct replacement in September 1994, although the Power Macintosh 7100, introduced a few months earlier, which used the same case as the 650 (originally used on the Macintosh IIvx), had a similar target audience.

There are two versions of the Centris 650: One with 4 MB of RAM soldered to the logic board and an FPU-less Motorola 68LC040 CPU, and one with 8 MB of logic board RAM, a full Motorola 68040, and added an onboard AAUI port for Ethernet. The higher-end model also came with 1MB VRAM installed, enabling 16-bit color at 640x480 resolution. The availability of 16-bit color was significant, as it was the standard bit depth of Apple's then-new QuickTime video standard. The Quadra 650 is also available in the 4 MB and 8 MB onboard RAM variations, but always has the 68040 and AAUI.

Vocal (Pet Shop Boys song)

"Vocal" is the second single from the Pet Shop Boys album Electric, released on 3 June 2013.

Background

"Vocal" was written during the writing process for the 2012 album Elysium, and was one of the earliest tracks written for the album. The track, however, wasn't included on the record as it didn't fit the rest of the "somber" and "reflective" material. It was instead recorded for Electric and was released as the album's second single.

Music video

The music video was directed by Joost Vandebrug. It is a tribute to rave culture and electronic music. It consists of a compilation of various amateur videos recorded circa the Summer of Rave in 1989.

Live performances

It is performed as the final encore on the Electric Tour.

Release formats

The single has been released in both digital and physical formats, with the latter containing the original album version along with 8 original remixes.

Charts

Because the song is over six minutes long and the single edit was never made available for purchase, it was ineligible to chart on most singles charts around the world, and only a few charts have ever included it, despite the single selling well.

KMXV

KMXV ("Mix 93.3") is a Top 40 (CHR) station based in Kansas City, Missouri, United States. The Steel City Media outlet operates at 93.3 MHz with an ERP of 100 kW. Its current slogan is "Kansas City's #1 Hit Music Station". It is also one of two Top 40's competing in the Kansas City Metropolitan Area, the other being KCHZ. The station's studios are located at Westport Center in Midtown Kansas City, and the transmitter site is in the city's East Side.

The station was sold off by CBS Radio to Wilks Broadcasting in November 2006 as part of a nationwide reduction of radio stations by CBS. On June 12, 2014, Wilks announced that it is selling its Kansas City cluster (of which KMXV is part of) to Pittsburgh-based Steel City Media. The sale was approved on September 26, 2014, and was consummated on September 30.

History

The station began in 1958 as KCMK-FM (Kansas City, Missouri/Kansas), a classical station, but had several format changes (primarily country) over the next sixteen years. County DJ Jack Wesley "Cactus Jack" Call was at the station (from KCKN) for one week when he was killed on January 25, 1963 in a car crash. Singer Patsy Cline sang at a benefit for him at Memorial Hall (Kansas City, Kansas) on March 3, 1963. She was unable to leave Kansas City the next day because the airport was fogged in and was killed in a plane crash on March 5, 1963 en route from Fairfax Airport to Nashville.

MIX

MIX is a hypothetical computer used in Donald Knuth's monograph, The Art of Computer Programming (TAOCP). MIX's model number is 1009, which was derived by combining the model numbers and names of several contemporaneous, commercial machines deemed significant by the author. ("MIX" also represents the value 1009 in Roman numerals.)

The 1960s-era MIX has since been superseded by a new (also hypothetical) computer architecture, MMIX, to be incorporated in forthcoming editions of TAOCP. Software implementations for both the MIX and MMIX architectures have been developed by Knuth and made freely available (named "MIXware" and "MMIXware", respectively).

Several derivatives of Knuth's MIX/MMIX emulators also exist. GNU MDK is one such software package; it is free and runs on a wide variety of platforms.

Their purpose for education is quite similar to John L. Hennessy's and David A. Patterson's DLX architecture, from Computer Organization and Design - The Hardware Software Interface.

Architecture

MIX (Email)

MIX is a high-performance, indexed, on-disk email storage system that is designed for use with the IMAP protocol. MIX was designed by Mark Crispin, the author of the IMAP protocol. Server support for it has been included in releases of UW IMAP since 2006, Panda IMAP, and Messaging Architects Netmail. MIX is also supported directly by the Alpine e-mail client.

Design

MIX mailboxes are directories containing several types of files, including a metadata file, an index file, a dynamic status data file, a threading/sorting cache file, and a collection of files containing message content. MIX mailboxes can also contain subordinate mailboxes, which are implemented as sub directories within the MIX directory.

The MIX format was designed with an emphasis on very high scalability, reliability, and performance, while efficiently supporting modern features of the IMAP protocol. MIX has been used successfully with mailboxes of 750,000 messages.

The base level MIX format has four files: a metadata file, an index file, a status file, and some set of message data files. The metadata file contains base-level data applicable to the entire mailbox; i.e., the UID validity, last assigned UID, and list of keywords. The index file contains pointers to each unexpunged message in the message data files, along with flags, size, and IMAP internaldate data. The status file contains per-message flags and keywords.

Future Crew

Future Crew was a Finnish demogroup who created PC demos and software, active mostly between 1987 and 1994.

History

The group was founded in 1986 by PSI (Sami Tammilehto) and JPM (Jussi Markula) as a Commodore 64 group, before moving to the PC demoscene in 1988; other members included, over time, Trug, Wildfire, Pixel, ICE, GORE, Abyss, Purple Motion, and Skaven, as well as several others not listed here.

Noteworthy demos by Future Crew include Unreal (released at Assembly 1992), Panic (released at The Party 1992) and Second Reality (released at Assembly 1993). Second Reality may be considered one of the most influential PC demos ever made. Future Crew was also responsible for the popular MOD editor Scream Tracker, which was fashioned after the Amiga Soundtracker, as well as the Advanced DigiPlayer sound editor and later became itself inspiration for other trackers like the Impulse Tracker.

Future Crew was co-organizer of the first Assembly demo party in 1992, and continued organizing the annual party until 1995, when the organization set up the Finnish company ASSEMBLY Organizing in order to "provide a solid financial basis for the events and a reliable partner for our sponsors". Long time Future Crew member Abyss is one of the party's main organizers.
