Alternating currentAlternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight.
Free Speech FlagThe Free Speech Flag is a symbol of personal liberty used to promote freedom of speech. Designed by artist John Marcotte, the flag and its colors correspond to a cryptographic key which enabled users to copy HD DVDs and Blu-ray Discs. It was created on May 1, 2007, during the AACS encryption key controversy. Marcotte was motivated to create the flag after the Motion Picture Association of America (MPAA) and the Advanced Access Content System Licensing Administrator (AACS LA) began issuing cease and desist letters to websites publishing the key 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 (commonly referred to as 09-F9).
