11069JUnitConv - Units of Measure Converterhttp://junitconv.tecnick.com/JUnitConv is a free Open Source universal Units of Measure Converter, it converts numbers from one unit of measure to another.
Built as a Java Applet, JUnitConv is platform-independent and highly-configurable, it supports an unlimited number of Units Categories, Units of Measure and Multiplier Prefixes that could be customized using external text files. You could setup your own data files using your preferred spoken language, units categories, units definitions and multiplier prefixes. The default configuration data files contains 580 basic units of measure definitions divided in 31 categories and 27 multiplier prefixes for a total of 15660 composed unitsJava > Applets > MiscellaneousOct 11, 2006Nicola Asuni - Tecnick.com S.r.l.
ColorPicker provides an intuitive graphical interface to display the hexadecimal code of the color selected by the user. The RGB value is passed to a JavaScript variable which could then be used to modify your web page dynamically or as form inputs. You could also change the color using JavaScript as shown in the example.
ColorPicker is available in 2 versions: the Freeware Edition and Professional Edition. The Freeware Edition is free for non-commercial use. It contains copyright messages on the applet and the status bar. These messages are absent in the Professional Edition. In addition, the Professional Edition gives you the right to use it on an unlimited number of web sites and integrate with your software or web products for distribution. Full details can be found at the online order page.
This type of interface provides a huge usability improvement over the alternatives. In fact, when you call 411, the operators use exactly this type of interface to quickly lookup a phone number based on the name of the entity you specify. The alternatives are dropdown boxes, which require painful scrolling, and multi-page narrowing of categories, which requires reading many options and multiple page requests. Imagine how long a directory assistance call would take if the 411 operators used those! Some example of where to use this type of interface would for eBay's category selection, or Yahoo Auto's automobile make and model selection. Alas, they do not use this technique yet.
The various parameters of the applet also allow you to specify a lower and upper bound for the colour values (so that they will always remain within a certain range) and to specify a seed for the random number generator. By giving the same seed (and start colour) to two or more bars, you can ensure that they remain synchronized. The two lower bars on this page are synchronized.
This java applet solves linear equations of two unknown variables. You have to take care of two points, while using this applet. First, you should only enter numbers only as coefficients. You can not use fractions or other expressions as coefficients. If your equations have fractions as coefficients, reduce them to decimal equivalents before entering them in the text boxes. For example, if your equation is like this:
