GRASS (the Geographic Resources Analysis Support System) is a software raster- and vector-based GIS (Geographic Information System), image processing system, graphics production system, and spatial modeling system. It contains many modules for raster data manipulation, vector data manipulation, rendering images on the monitor or paper, multispectral image geocoding and processing, point data management and general data management. It also has tools for interfacing with digitizers, scanners, and the PostgreSQL, DBF, and ODBC connected databases. GRASS operates on all common operating systems.
Pogo is probably the simplest and fastest audio player for Linux. Its elementary-inspired design uses the screen-space very efficiently. Pogo is especially well-suited for people who organize their music by albums on the hard drive. The main interface components are a directory tree and a playlist that groups albums in an innovative way.
