Electronic Engineering Tool is a Web-based tool that includes an electronic formula calculator and converter functions. It very useful when working with electronics, both for engineers and amateurs. For example, it includes converters for dBm-to-Watt and Fahrenheit-to-Celsius, and it can calculate Ohm's law, filters, thermal resistant C/W, SWR, coil inductance, capacitor capacity, and more.
Software Engineering Environment (SEE) provides an information manufacturing platform for software development. It makes information sharing very convenient by allowing all information to be customized dynamically and letting users modify or add their own information structures at any time. It provides various predefined selections for information attributes that correspond to information manufacturing patterns. Although designed for software development, it could be used for managing any information, including book registries, personnel lists, and financial reports.
Visitors is a very fast Web log analyzer. It can process up to 150,000 lines/second of logs on a modern PC, outputs statistics in plain-text or HTML, and generates a number of Google-specific reports and graphviz graphs of visitors' common paths. It does not require any kind of configuration, nor does it need to be told the exact format of the Web log file to process.
