Free rapid prototyping software for windows

"Rapid Evolution" is a free and useful music library tool for DJs, designed to be used while you mix. It helps profile your songs by saving important properties, such as the bpm, key, time signature, styles, comments, etc. You can then instantly see which songs are within bpm range, in key harmonically and in similar styles.
More importantly, it lets you save comments and information about each individual mix you come up with. Use it to enhance your knowledge of your music and remember the important details of what you do. You will quickly take your mixing to new levels! the software includes automatic bpm and key detection, as well as tools to determine this information yourself--a bpm tapper and a midi keyboard. It also lets you share all song and mix information with other DJs automatically through the central mixshare site. Use it and start evolving!

Readymade Website Prototype 1.0 is a tool to design a Web site. Although features are limited, it is a fully functional Web site including a skin file to control the site appearance. The full versions allow dynamic control of the interface structure and site layout through an external settings file.

This software application is a leading open-source data mining solution RapidMiner is the world-wide leading open-source data mining solution due to the combination of its functional range and its leading-edge technologies. Applications of RapidMiner cover a wide range of real-world data mining tasks
Use RapidMiner and explore your data! Simplify the construction of experiments and the evaluation of different approaches. Try to find the best combination of preprocessing and learning steps or let RapidMiner do that automatically for you.
Main features:
- freely available open-source knowledge discovery environment
- 100% pure Java (runs on every major platform and operating system)
- KD processes are modeled as simple operator trees which is both intuitive and powerful
- operator trees or subtrees can be saved as building blocks for later re-use
- internal XML representation ensures standardized interchange format of data mining experiments
- simple scripting language allowing for automatic large-scale experiments
- multi-layered data view concept ensures efficient and transparent data handling
- Flexibility in using RapidMiner:
- graphical user interface (GUI) for interactive prototyping
- command line mode (batch mode) for automated large-scale applications
- Java API (application programming interface) to ease usage of RapidMiner from your own programs
- simple plugin and extension mechanisms, a broad variety of plugins already exists and you can easily add your own
- powerful plotting facility offering a large set of sophisticated high-dimensional visualization techniques for data and models
- more than 400 machine learning, evaluation, in- and output, pre- and post-processing, and visualization operators plus numerous meta optimization schemes
- machine learning library WEKA fully integrated (WEKA web page)
- RapidMiner was successfully applied on a wide range of applications where its rapid prototyping abilities demonstrated their usefulness, including text mining, multimedia mining, feature engineering, data stream mining and tracking drifting concepts, development of ensemble methods, and distributed data mining.

Rapid Backup application was designed to be an efficient, easy-to-use personal file backup tool that will allow you to safeguard your data.
Rapid Backup supports replication of one or more local files and directories to a destination, such as another hard drive, Zip disk, or floppy disk. In the future, it will also support targets like tapes or remote FTP sites.
This version of Rapid Backup is designed to give a preview of its development. Many features havent been completed yet, but enough of the basics are done to make it a useful tool.
Rapid Backup consists of two main components: the service and the user interface. The service is a small program that runs all the time. It handles all management of backups. The user interface runs only while you are configuring the serivce. The user interface can be closed while the service continues running backups, saving memory.
A job is the basic unit that Rapid Backup uses to organize your data. A job includes one or more source files or directories, and the target location. For example, you might have a job with the source directory C:My Documents and the target location D:Backup Data.
