A torrent tracker is a piece of software which tracks Torrents. It will record the number of leechers, number of seeders, how large the torrent is, what files are contained in the torrent, and how many times the torrent has been downloaded. You can think of it like a statistics tracker for torrents.
The unit of the Maya writing system is the glyphic cartouche, which is equivalent to the words and sentences of a modern language. Maya cartouches included at least three or four glyphs and as many as fifty. Each cartouche contained various glyphs, as well as prefixes and suffixes. There is no Maya alphabet.
The Maya used embroidery to add even more color to their clothing. The poor did not have much time to spend on personal grooming, so they took good care of their clothes. On festival days, they wore their finery. But when they got home, they put their good clothes carefully away. Clothes had to last.
