.22 TCM
The 22TCM (.22 Tuason Craig Micromagnum) is a proprietary bottle-necked cartridge developed by Fred Craig and Rock Island Armory. Before the cartridge was commercialized, it was called the 22 Micro-Mag. Standard factory loads are 40-grain jacketed soft hollow point. Armscor has announced a new round the 22TCM9R which will be the same case as the 22TCM but have an overall length of the 9×19mm round. The company plans to release this round in summer of 2015 with a Glock 22TCM9R conversion slide to allow the 22TCM to fit in a 9mm length magazine, hence the "9R" designation. The 22TCM9R will in fact still be a 39 grain bullet but will be a fully jacketed hollow point instead.
The 22TCM is based on the 5.56×45mm NATO case, shortened so that the shoulder is at approximately the same length as a .38 Super cartridge. The cartridge is designed to feed from a Para-Ordnance-style double-column .38 Super magazine. Currently only Rock Island Armory catalogs firearms chambered in 22TCM: a 1911 style semi-auto pistol (also available with optional additional 9mm barrel and recoil spring), and a bolt-action rifle (which reportedly can use the same magazines as the pistols); and only Armscor (the parent company of Rock Island Armory) manufactures ammunition.
Turner Classic Movies (UK and Ireland)
Turner Classic Movies (commonly abbreviated as TCM) is a subscription digital television channel featuring classic movies, mostly from the Turner Entertainment and Warner Bros. film libraries, which include many MGM, United Artists, RKO and Warner Bros. titles. This version of the channel is available in the United States, United Kingdom, France (TCM Cinéma), Spain (Canal TCM), Nordic countries, Middle East and Africa with relevant subtitles and localised advertising.
History
It was launched in 1999, when its predecessor, TNT, dropped its film programming to become a general entertainment channel. Its penetration increased when it took over TNT's space on various platforms on 1 July 2000.
Unlike other versions of Turner Classic Movies and the other Turner channels in the UK, Turner Classic Movies UK was for a long time broadcast free-to-air. The channel became encrypted in January 2004 when it joined Sky's subscription packages.
In 2009, Turner Classic Movies received a graphical makeover and a new logo in an attempt to attract a younger audience. With the makeover several new films were added to the channel's catalogue. A high definition version of the channel launched on 4 September 2012, at the same time the standard definition version began broadcasting in 16:9 widescreen, whereas Turner Classic Movies 2 continued to be broadcast in 4:3.
Web search engine
A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.
History
Internet search engines themselves predate the debut of the Web in December 1990. The Whois user search dates back to 1982 and the Knowbot Information Service multi-network user search was first implemented in 1989. The first well documented search engine that searched content files, namely FTP files was Archie, which debuted on 10 September 1990.
Prior to September 1993 the World Wide Web was entirely indexed by hand. There was a list of webservers edited by Tim Berners-Lee and hosted on the CERN webserver. One historical snapshot of the list in 1992 remains, but as more and more web servers went online the central list could no longer keep up. On the NCSA site, new servers were announced under the title "What's New!"
