TCM may refer to:
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.
The M45 Quadmount (nicknamed the "meat chopper" and "Krautmower" for its high rate of fire) was a weapon mounting consisting of four of the "HB", or "heavy barrel" .50 caliber M2 Browning machine guns (of the M2 Turret Type (TT) variant) mounted in pairs on each side of an open, electrically powered turret. It was developed by the W. L. Maxson Corporation to replace the earlier M33 twin mount (also from Maxson). Although designed as an anti-aircraft weapon, it was also used against ground targets. Introduced in 1943 during World War II, it remained in US service as late as the Vietnam War.
In order to develop a mobile anti-aircraft weapon, several 0.5 inch (12.7 mm) twin machine gun mounts were tested on the chassis of the M2 half-track including Bendix, Martin Aircraft Company, and Maxson. The Maxson M33 turret mount was preferred and - on the larger M3 half-track (T1E2) - was accepted for service in 1942 as the M13 Multiple Gun Motor Carriage. The mount was also used on the similar M5 half track as the M14 Multiple Gun Motor Carriage.
Flashback is the eighth studio album, and a compilation album of outtakes and rare songs released by Joan Jett and the Blackhearts. The album was initially released in late 1993 and was reissued in 1998 with a slightly different track listing. The 1998 version dropped five tracks from the 1993 release: "Summertime Blues", "Louie Louie", "Star Star", "Stand Up for Yourself," and "Call Me Lightning" and replaced them with "Real Wild Child (Wild One)", a live version of " Bad Reputation", and "Right 'Til the End", which was only available on the cassette version of the 1993 release. "Call Me Lightning" and "Summertime Blues" were later added as bonus tracks on reissues of Bad Reputation and "Louie Louie" became a bonus track on the reissue of I Love Rock 'N Roll. "Star Star" was included as an unlisted "surprise" track on the 1983 cassette release of Album, but was later removed after the original cassette was pulled from some stores because of non-labelled "explicit" track lyrics. The song was restored on the CD release.
Trojan BackDoor.Flashback, commonly referred to as the Flashback Trojan, is a Trojan horse affecting personal computer systems running Mac OS X. The first variant of Flashback was discovered by antivirus company Intego in September 2011.
According to the Russian antivirus company Dr. Web, a modified version of the "BackDoor.Flashback.39" variant of the Flashback Trojan has infected over 600,000 Mac computers, forming a botnet that includes 274 bots located in Cupertino, California. The findings were confirmed one day later by another computer security firm, Kaspersky Lab. This variant of the malware was first detected in April 2012 by Finland-based computer security firm F-Secure. Dr. Web estimated that in early April 2012, 56.6% of infected computers were located within the United States, 19.8% in Canada, 12.8% in the United Kingdom and 6.1% in Australia.
The Trojan targets a Java vulnerability on Mac OS X. The system is infected after the user is redirected to a compromised bogus site, where JavaScript code causes an applet containing an exploit to load. An executable file is saved on the local machine, which is used to download and run malicious code from a remote location. The malware also switches between various servers for optimised load balancing. Each bot is given a unique ID that is sent to the control server. The trojan, however, will only infect the user visiting the infected web page, meaning other users on the computer are not infected unless their user accounts have been infected separately.
"Flashback" is the fifth Korean single album released by South Korean girl group, After School. The maxi-single marks the first appearance of fifth generation member, Kaeun. This also marks the first comeback since Kahi's official graduation from the group to pursue a solo career.

A day after Lizzy's teaser photo, Uie's photo was revealed, followed by Nana & Raina, Jungah, Juyeon, and lastly E-Young & Kaeun. Although it was speculated that Nana would become the leader, Pledis announced the empty leader position with the graduation of Kahi will be taken on by Jungah.
