Knowledge 1: The Rachel Maddow Show
The Rachel Maddow Show (also abbreviated TRMS) is a daily news and opinion television program that airs on MSNBC, running in the 9:00 pm ET timeslot Monday through Friday. It is hosted by Rachel Maddow, who gained a public profile via her frequent appearances as a progressive pundit on programs aired by MSNBC. It is based on her former radio show of the same name.

MSNBC is an American news cable and satellite television network that provides news coverage and political commentary from NBC News on current events. MSNBC is owned by the NBCUniversal News Group, a unit of the NBCUniversal Television Group division of NBCUniversal (all of which are ultimately owned by Comcast). MSNBC and its website were founded in 1996 under a partnership between Microsoft and General Electric's NBC unit, hence the network's naming. Although they had the same name, msnbc.com and MSNBC maintained separate corporate structures and news operations. msnbc.com was headquartered on the Microsoft campus in Redmond, Washington while MSNBC operated out of NBC's headquarters in New York City. Microsoft divested its stakes in the MSNBC channel in 2005 and in msnbc.com in July 2012. The general news site was rebranded as NBCNews.com, and a new msnbc.com was created as the online home of the cable channel. [SEP] Knowledge 3: Hyper-V

Starting with Windows 8, Hyper - V superseded Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper - V can be configured to expose individual virtual machines to one or more networks.

Drift: The Unmooring of American Military Power is a 2012 book by Rachel Maddow. Her first book, "Drift" explores the premise that the manner in which the United States goes to war has gradually become more secretive and less democratic. In "Drift", Maddow examines how American declarations of war have incrementally shifted from being congressionally approved to being centralized in the hands of the American president. The book's scope spans from the Vietnam War to the wars in Iraq and Afghanistan.
