Piper can be looked at in two ways: as a distributed scripting or programming language, and as a distributed bioinformatics collaboration tool. In the Piper paradigm everything is a node, certain nodes input and output data, every node has an Internet address, and nodes can be linked to define relationships, procedural steps and data flow. A node might represent an online database, for example. Each node has a Graphical User Interface (GUI) defined in XML. The interface has XML descriptions and some widgets. In bioinformatics, for example, a user might have a molecule widget to work with. With the Pied/Piper User Interface (Pied/Piper UI), the user has access to a Peer-To-Peer graphical scripting language (or if low level objects are linked, a graphical programming language). Piper is licensed under the GNU Lesser General Public License (LGPL).

Supreme Court Decides Unanimously Against Grokster
Updating as we go. Supremes have ruled 9-0 in favor of the studios in MGM v Grokster. But does the decision have wider import? Is it a death knell for tech? It's starting to look like the answer is no. (Jun 27, 2005)
