RR's Unit Converter is an useful tool for any kind of simple or compound unit conversions, using double precision 64-bit format values and operations, with build in dictionary for over 1000 units. Scientist, engineers, students or anyone involved in scientific, financial, archeological or other activities where unit conversions are required will found this program useful. By using a careful developed algorithm, unit conversion factors could be defined between any two units. This feature allows you to use the most precise known unit conversion factor between two units. Therefor, any unit conversions will be performed with high precision. The compound unit feature gives you more flexibility to perform complex transformation and calculation. You could define your own values for fractions. Input fraction: both values, output fraction: bellow value only( above value is the result). RR's Unit Converter comes with a large database of units and a dictionary with definitions for almost all units in the database is included for your convenience. You may even create categories and add your own units to the database. All those features make RR's Unit Converter a powerful tool for all those involved in activities that require any kind of unit conversion.

MediaSnooper is a personal system for indexing and searching for files in a local network.
Local networks are a great source of various information. And it’s sometimes very difficult to find something important in a large network. MediaSnooper can be very useful in this case.
The search is carried out by an index database, so the time of showing results reduces to fractions of a second. Special features for finding mp3 files are supported. You can specify additional criteria and filters for the search query, and sort search results by different parameters. For example, you can specify in the query that you want to find a list of new mp3 or avi files that appeared in the network within the past week.
A built-in download manager makes the downloading of files and folders you find much easier as it dynamically traces the availability of the remote resource. It supports resuming interrupted downloads and synchronizing finished downloads with remote sources.

Main features:
- indexing the resources of your local network in background mode
- searching by filename, using wildcards
- searching by additional information stored in mp3 files (ID3 tags): artist, track title, album
- many additional search criteria and filters: file size, length of audio record, modification date, date of inclusion into index, bit rate, etc.
- sorting search results by different parameters
- visual indication of current state of the resource (available\unavailable)
- a built-in navigator that allows viewing indexed resources of the local network in a convenient way
- complete support of Unicode
- a built-in download manager that allows downloading separate files and entire folders, and resumes uncompleted downloads when it has access to the remote resource
- the download manager also allows organizing easy synchronization of local folders with shared folders on other computers

Rapid-Pi is an add-on for Microsoft Word (and other word processors) that will transform the way you enter mathematical formulae, equations and expressions into documents.

Rapid-Pi was designed with a single purpose in mind - to save you time when editing math in documents. Rapid-Pi's text-based input is a simply faster way to input math.

Most equation editing programs require you to click on toolbar buttons or go through menus in order to insert symbols and expressions. This process is inherently slow and painful. Even simple things like fractions take up too much time - you have to click on the fraction button, then click in the numerator, type the numerator, click in the denominator and type the denominator. Consider how much faster and easier it would be if you could simply type "1/4". That's exactly what you can do with Rapid-Pi.

NOTE: Rapid-Pi is an add-on for your existing word processor application (like Microsoft Word), not a stand-alone program. This means that you will continue to use your favorite word processor, inserting Rapid-Pi equations into your document whenever you need to enter math. Inserting a Rapid-Pi equation is easy - just click on the Rapid-Pi button on Microsoft Word's toolbar (toolbar button is currently only provided for Microsoft Word 2000 and later).

Rapid-Pi supports a large number of mathematical symbols and expressions, including all symbols supported by Microsoft Equation Editor.

If you don't know the keyword for a symbol, you just click on the appropriate toolbar button and Rapid-Pi will insert the text for you (for example, ".a" for lower-case alpha, ".int" for integral, etc). Soon, you'll probably find that you don't need to use the toolbar 90% of time. The toolbar will still be available for the occasions when you need to enter a symbol that you've never used before (or if you forget how to enter a rarely-used symbol).

CASC helps calculate recipes for solution preparation regardles of number of compunds used. Built in concentration calculator converts concentrations between percent, molarity, molality and molar fractions, automatically taking density changes into account thanks to built in database of substances. Thanks to the flexible user interface concentration calculator can be also used to find answers to most solution questions you may think off or find in textbooks as it can find any unknown - concentration, amount of solution, amount of substance - if other values are given. There is also solution mixer - which does almost every kind of calculations involving three solutions - two mixed and one obtained. Solution mixer has the same flexibility of use allowing you to find any unknown for any given set of data. Registered version database contains over 300 compounds with density data tables so you can use it instead of a handbook.
