Eclipse is a kind of universal tool platform - an open extensible IDE for anything and nothing in particular. The real value of Eclipse comes from tool plug-ins that "teach" Eclipse how to work with things - java files, web content, graphics, video, etc. Eclipse allows you to independently develop tools that integrate with other people's tools seamlessly.
CMME (Content Management Made Easy) is a Web content management system that aims to be easy to use, doesn't have many requirements, and is still reasonably flexible. It doesn't need a database, doesn't have extensive administrative needs, and works more or less like a wiki. New pages can be made on the fly, rather than through an administrative page.
The Java Wikipedia API (Bliki engine) is a parser library for converting Wikipedia/Mediawiki syntax to HTML. It supports wiki tags for bold, italic, headers, nowiki, source, table of contents, tables, lists, categories, footnotes (references), images, syntax highlighting of source code fragments, templates, and template parser functions.
Splunk Hogs is a quick Perl script that was written to find what systems are sending too many events to Splunk and using up all the licenses. This is good for several reasons: developers will turn debugging on and use up all the licenses, which will help catch it early; INFO messages get turned on and useless events will be sent, filling up the licenses; issues will be detected that were being ignored by others. The advantage over Splunk's SaveSearch is that it outputs the raw data, so you can import it into Nagios or other tools. It collects raw data from Splunk that consists of the host, Splunk server, and the count of events that took place.
HC-SR04 Ultrasonic Arduino Library is specifically for the HC-SR04 ultrasonic sensor. It features timing, metric conversion, and standard deviation methods, plus a few support methods. It is written in C++ to conserve the namespace. The conversion formula can be easily modified to optimize the accuracy of conversion at different distances for inches and centimeters. Multiple buffers of different lengths can be created for determining standard deviation.
