The concept of an average can be applied to a stream of data as well as a bounded set, the goal being to find a value that recent data clusters about in some way. The stream may be distributed in time, as in samples taken by some data acquisition system from which we want to remove noise, or in space, as in pixels in an image from which we want to extract some property. An easy-to-understand and widely used application of average to a stream is the simple moving average in which we compute the arithmetic mean of the most recent N data items in the stream. To advance one position in the stream, we add 1/N times the new data item and subtract 1/N times the data item N places back in the stream.

Most nation-states have anthems, defined as ""a song, as of praise, devotion, or patriotism""; most anthems are either marches or hymns in style. A hymn can become a national anthem by a provision in the state's constitution, by a law enacted by its legislature, or simply by tradition. A royal anthem is a patriotic song similar to a national anthem, but it specifically praises or prays for a monarch or royal dynasty. Such anthems are usually performed at public appearances by the monarch or during other events of royal importance. Some states use the royal anthem as the national anthem, such as the anthem of Jordan.

... I do think the Internet’s under much greater attack than it has been in the past. Governments are now afraid of the Internet because of the Middle East stuff, and so they’re a little more willing to listen to what I see as a lot of commercial interests that just want to make money by restricting people’s freedoms. But they’ve also seen a tremendous user reaction, like the backlash against SOPA. I think that governments fight users’ freedoms at their own peril.

Some of the main types of human freedom are: freedom to life, freedom of association, freedom of belief, freedom of speech, freedom to express oneself, freedom of the press, freedom to choose one's state in life. However, the civil constitutions of each country have different definitions of the freedoms allowed to the citizens. It has been argued that any law limits freedom, since it sets limits on what people may do.
