A large piece of compressed ice, or a glacier, would appear blue as large quantities of water appear blue. The latter is because the water molecule absorbs other colors more efficiently than blue. The other reason for the blue color of glaciers is the lack of air bubbles.ong, sinuous glacial deposits are called eskers. Eskers are composed of sand and gravel that was deposited by meltwater streams that flowed through ice tunnels within or beneath a glacier. They remain after the ice melts, with heights exceeding 100 meters and lengths of as long as 100 km.
Open-source license. An open-source license is a type of license for computer software and other products that allows the source code, blueprint or design to be used, modified and/or shared under defined terms and conditions.
Open Source means that the code and software are free to the public. Many Linux flavored OS's used to be this way - and they still are . . . to a point. What they are doing now is selling the current version and when that version becomes outdated by later releases they put that version into the 'open source' bit bucket for anyone to grab.
