Music21 is a set of tools for helping scholars and other active listeners answer questions about music quickly and simply. If you’ve ever asked yourself a question like, “I wonder how often Bach does that” or “I wish I knew which band was the first to use these chords in this order,” or “I’ll bet we’d know more about Renaissance counterpoint (or Indian ragas or post-tonal pitch structures or the form of minuets) if I could write a program to automatically write more of them,” then music21 can help you with your work.

The CLEVER search engine incorporates several algorithms that make use of the Web's hyperlink structure for discovering high-quality information. It can be exceedingly difficult to locate resources on the World Wide Web that are both high-quality and relevant to a user's informational needs. Traditional automated search methods for locating information on the Web are easily overwhelmed by low-quality and unrelated content. Second generation search engines have to have effective methods for focusing on the most authoritative documents. The rich structure implicit in hyperlinks among Web documents offers a simple, and effective, means to deal with many of these problems. Additional Information: Publications:

JayWalker is an open-source build and deployment analysis tool which interrogates a Java application's compiled artifacts and generates static and interactive graphical reports from it. In turn, a software professional can interpret and use these reports to improve software quality and to understand the current state of the software application in question.
Although there are quite a few dependency analysis tools on the market, JayWalker is different because:
* It walks the class files rather than the source files
* It can interrogate nested archives (i.e. a JAR within a WAR within an EAR file)
* It can detect a variety of conflicts that can be identified at build and deployment time in an effort to minimize runtime dependency errors.
* It can be incorporated into a continuous integration solution so conflicts can be identified as they are introduced into source code control rather than addressing errors at runtime.
* It can be run standalone via the commandline on a system which just has a JRE installed
* Other dependency tools are package or class specific. JayWalker has support for archives, packages, and classes.
* Report attributes can be toggled on or off
* Walking across classlist elements can be done in several different ways:
o Deep (default) - recursively follow all paths
o Shallow - recursively follow paths up to and including a boundary element
o System - recursively follow paths up to a boundary element which is not part of the deployment, but is provided by a server or environment.
Opticks is an expandable remote sensing and imagery analysis software platform that is free and open source. If you've used other commercial tools like: ERDAS IMAGINE, RemoteView, ENVI, or SOCET GXP, then you need to give Opticks a try. Unlike other competing tools, you can add capability to Opticks by creating an extension. Opticks provides the most advanced extension capability of any other remote sensing tool on the market.
