	RenameWand  License: Freeware
	Ever wished there was an easy way to rename files or directories quickly without having to struggle with clunky graphical interfaces? RenameWand can help you with that! RenameWand is a simple command-line utility for renaming files or directories using an intuitive but powerful syntax (like regex, only much easier). Perform string operations (e.g. case conversions, rearrangements of substrings), arithmetic operations (e.g. on the numbers in the filename), enumerate files (e.g. by name, size, time, or other attributes), insert time stamps, and many more file and system attributes with ease! RenameWand supports pattern matching using glob patterns and wildcards *, ?, [ ], and { }, as well as a special register capture group construct. Runs on any OS with the Java Runtime Environment (JRE 6+). RenameWand is free and open source software written in Java and released under the GNU GPL license (version 3). MAIN FEATURES:  * Supports the common glob patterns and wildcards *, ?, [ ], and { } for matching filenames.  * Use a special register capture group construct to capture strings of characters in the filename.  * Macros are defined for a variety of file and system attributes, such as file name (FN.*), file size (FS.*), file last-modified time (FT.*), current time (CT.*), system environment variables (ENV.*), and system properties (SYS.*).  * A wide range of operations can be applied to registers and macros: case conversions (e.g. *.upper, *.lower, *.title), substring operations (e.g. myreg[1:3]), arithmetic operations (e.g. a/(b-c)^d), enumeration operations (e.g. #FT, #(myreg1+myreg2)), and more.  * File rename operations are sequenced so that they are conflict-free, and temporary filenames are automatically used when necessary.

	Memorize digits 01  License: Freeware
	Memorize the nombers. You can do it! We live in a see of numbers: social security numbers, dates, license plate numbers, prices, zip codes, etc. Yet without a special technique, numbers are very difficult to memorize because they are so hard to associate. Our brains think with pictures, not with numbers. It's easier for us to visualize an elephant eating a ham sandwich than to picture the string of numbers 32334698. But what if we could mentally convert a number into a word, a word that represents a mental picture? It turns out that we can. Author: Mind concentration games| Date: 01-01-2006 | Size: 10 KB

Before and after the training course each participant has been tested with using of Zener cards. It is interesting, that this experiment supposes visual telepathic communication, while Learn Telepathy is based on the lexical one. However, those who have succeeded in the Learn Telepathy testing have had excellent results in the experiment with using of Zener cards. 60% of them have guessed 10 cards and more out of 30 trials with 5 cards, while average probability of this fact is between 1% and 5%.
