Gauss Jordan Elimination Calcula.zip by Chuck Mire (Rate this file/View comments) 
Gauss Jordan Elimination Calculator  Convert an augmented square matrix into Reduced Row Echelon Form. Solve systems of simultaneous linear equations input in augmented matrix format. Full accuracy is assured by only calculating with the fractional mode solution, because imprecision can take place in floating point mode. If the data was in an exact floating point format, then convert the data to a fraction (proper or improper) and enter the data that way. However, after the calculation is complete in the fractional mode, you can view the floating point solution if you desire. The attached zip file contains the Windows executable, the source code, and a full explanation in a text file.

Gauss Jordan Elimination Calculator.pdf by Chuck Mire (Rate this file/View comments) 
I am amazed how often I can arrive at a solution by just punching in numbers as they come to mind. I even wrote a quick pseudorandom number generator where I can control the lower value, the upper value, and the amount of pseudorandom numbers to generate. I have been using a lower value of "0", an upper value of "25" and generating 42 numbers (the maximum input for a 6 X 7 augmented matrix). The attached PDF shows screen shots of one such run of the Calculator using the numbers that are generated. I find it amazing just how many times a solution is forthcoming with this pseudorandom input approach.

GroupIt.zip by Chuck Mire (Rate this file/View comments) 
GroupIt.exe is a Windows executable which will format a continuous string of characters that are all greater than CHR$(32) into groups from 1 to 79 characters with a space between each group. Furthermore, each line will break into a new line when the total length of a line is less than or equal to 79 characters. I specifically use this program to format the output of two of my other programs: Base256 File To Base10 File.exe and File Reader to DNA EncryptedSequence Writer.exe GroupIt.exe will also reverse the process and UnGroup its output back to the original string of characters. I use the formatted output to generate two other pastimes that I enjoy: Creating and sending Morse Code files and creating and sending QR Codes. The zip file contains the Windows executable, the source code, and a PDF with examples, QR Codes and a screenshot.

Keyboard & Player Piano.zip by Chuck Mire (Rate this file/View comments) 
Keyboard & Player Piano is a Windows executable that is designed to compose a song using the computer keyboard (Keyboard Mode) in order for the user to create and save a text file so that the program can playback the music composition (Player Piano Mode). It allows any user who can hum a tune to create music  even if the user cannot read a note of music (like me). The syntax used in the text file music composition is unique to this program and is explained in the included PDF file. The attached zip file contains the source code, the windows executable, the PDF explanatory file with screenshots, and a few music composition text files. One advantage of my keyboard is that it uses the same keys as a Virtual Midi Piano Keyboard which is available as freeware here: http://vmpk.sourceforge.net/ As you probably know, MIDI has many more capabilities that than what the PLAY command has to offer  including changing instruments. So once you have pecked out a song using my program, you can write down the keyboard keys and then use the same keys to play the composition using the Virtual Midi Piano Keyboard.

Logarithmic Encryption.zip by Chuck Mire (Rate this file/View comments) 
Logarithmic Encryption is a Windows executable program that uses logarithms to encrypt/decrypt files. To see how this program works, first run Logarithmic Encryption Simulation.exe which will ONLY SIMULATE, as a standalone program, the SAME algorithm that the REAL encryption program uses. SYMBOLS USED: LOG = Logarithm (Base 10); Ln = Natural Logarithm (Base e); ! = Single Precision FloatingPoint Number Variable (7digits precision); $ = String Variable (can be created with any ASCII characters); ASC = (Reserved Word) Computes the ASCII Value of a Byte Character String (0 to 255); CHR$ = (Reserved Word) 1Byte Character String; MKS$ = (Reserved Word) Single Precision FloatingPoint Number made into a 4Byte String (4Bytes); CVS = (Reserved Word) 4Byte String converted back into a Single Precision FloatingPoint Number. First, the Sender Zips the DEcrypted file to preserve the file name and extension. This also compresses the file before encryption. Next, the Sender uses Logarithmic Encryption.exe to GET each byte of the DEcrypted Zip file which then computes a "Spread Spectrum" of PseudoRandom NumberBases in order to calculate the Logarithms of each Byte, which is PUT into an ENcrypted file and then sent to the Receiver. The Receiver uses Logarithmic Encryption.exe to GET the Logarithms in the ENcrypted file which then computes the same "Spread Spectrum" PseudoRandom NumberBases to calculate each original Byte, which is PUT into a DEcrypted Zip file. Then the Receiver UnZips the DEcrypted Zip file, which contains the original DEcrypted file. The Logarithms by themselves do not furnish the necessary information to compute the original bytes of the DEcrypted file because there are three variables: (1) The Byte ASCII value (incremented by 2)  only the range from 2 to 257 is known, so it could be ANY of these values. (The simulation program explains why the ASCII Value is incremented by + 2) (2) The PseudoRandom NumberBases (unknown  except to the Sender and Receiver using the SAME Parameters). (3) The LOG(Byte ASCII Values + 2) in the PseudoRandom NumberBases. The only EXACT variable known is the last one, (3): The LOG(Byte ASCII values + 2) in the UNKNOWN PseudoRandom NumberBases. Here is the formula that illustrates why the NumberBase remains unknown: NumberBase = (ANY ASCII + 2 value) ^ (1 / NumberBaseLOG) The NumberBase changes with different ASCII + 2 values. One needs to know two EXACT variables to Decrypt the file.

Logic Game Solver.zip by Chuck Mire (Rate this file/View comments) 
Logic Game Solver is an aid to solving logic game problems by creating a "spreadsheet type" grid that can be filled with a true or false mark besides any and all of the variables. There can be anywhere from 3 to 15 Variable TYPES and up to (30 \ TYPES) INDIVIDUALS per TYPE. In addition, the program has an "Auto Fill" option that can be used selectively or continuously to fill in portions of the grid that can be logically filled. If their is a logical error, the logical engine will inform you, but you will have to scan the grid to see where you went wrong. The attached PDF explains the program in detail, and includes screenshots. Please read! Here is a source for many logic game problems on the web: http://www.puzzles.com/Projects/AllLogicProblems.html I recommend that you just think your way slowly through logic programs, one step at a time. You will find that you can only partially complete a line when going through the logic statements the first time. But as the grid is filled out you will see that when you go through the problem again, more conclusions are obtained. Also, regarding the "Auto Fill", I highly recommend that when using it, you answer the next prompt "Auto Fill from now on (Yes or No) with NO. If you have made a logic error, it is much easier to correct that way. If you have saved a file that you have set to always "Auto Fill" and you wish to remove the "Auto Fill" always, just open the file in a text editor such as Notepad, and change the 3rd number down the column from a 1 to 0, and then save it. Problem solved. When I first set up a logic problem, I save the initial file as Setup.dat. Then I load Setup.dat back in and start solving the problem. At this point, I save the file as Solution.dat. That way, if I make a gross error, I can just use the Setup.dat file and start all over again instead of having to reenter the data from scratch. Also, you can leave the problem where you are at and come back to it at a later time to work on it again.The attached zip file contains the source code, the Windows executable, the PDF, a famous Einstein puzzle to solve with its setup file already created, Einstein.dat. Try out the logic puzzles on the web at the url I have given above because many of them are quite easy to solve. Once you get the hang of it, then try the more difficult Einstein puzzle that is attached in the zip file. Have fun!

Magic Square Generator.zip by Chuck Mire (Rate this file/View comments) 
Magic Square Generator.exe is a Windows executable that will generate OddOrder Magic Squares from Order 3 through Order 63. The numbering starts at the number one and increments by one through the square of the Order with no number duplication. For instance, for an order 63, the numbering goes from 1 through 63 squared (3969). The sum of any row or column or diagonal will add up to the Magic Sum which is computed by the following formula: Magic Sum = Order * (Order ^ 2 + 1) / 2. For example, the Magic Sum for the OddOrder 63 Magic Square = 63 * (63 * 63 + 1) / 2 = 125, 055. Two different magic squares can be generated for each order by using the Staircase or Pyramid method. Either one will generate the same Magic Sum for that order. The results can either be shown on screen only or saved to a formatted text file: Magic.txt (This file is saved in the same location as the program and is overwritten for each run of the program). The zip file contains the source code, the Windows executable, a PDF with screenshots, and four (4) example PDF files.

Morse Code Trainer.zip by Chuck Mire (Rate this file/View comments) 
Morse Code Trainer.exe is a Windows executable that allows you to learn and practice Morse Code with choices of 7 octaves, 7 pitches, and a range of tempos from 96 to 255. This method treats Morse Code as an oral language made up of letters, then words, and finally sentences of increasing speed and complexity. The range of Words Per Minute are from 12 WPM to almost 31 WPM. The Formula is: Tempo = 8 * WPM or WPM = Tempo / 8. For example, 15 WPM = 8 * 15 = Tempo 120. 30 WPM = 8 * 30 = Tempo 240. The zip file contains the source code, the Windows executable, and a PDF with multiple screen shots.
