<p>This recipe shows how to generate a PDF cheat sheet, that contains a table for conversion of the numbers 0 to 255 (the numbers that can fit in one byte) between binary, octal, decimal and hexadecimal representations. The table has four columns, one for each of those bases, and 256 rows, for the numbers 0 to 255.</p>
<p>TO use the table, you can look for a number, say in decimal, in the Dec(imal) column (or use the search function of your PDF viewer), then when you find it in some row, just look at the other 3 columns in that row, to find the value of that number in binary, octal and hexadecimal. And use the same procedure if starting with a number in any of the other three bases.</p>
data_dump.py, like the Unix od (octal dump) command (Python)

<p>This recipe implements a simple data dump tool, roughly like the od command of Unix, which stands for octal dump (though od can also dump data in hex and other formats). This tool dumps data in character and hex formats, in this version. This is data_dump.py version 1.</p>
A Shell, Binary To Hexadecimal To Decimal Demo... (Bash)

<p>This little DEMO may be common knowledge to the big guns but not to amateurs like myself, so......</p>
<p>This is an Apple Macbbok Shell/Terminal DEMO shell script to show how to:-</p>
<p>1) Create a binary file...
2) Save it to your DEFAULT /directory/drwawer/folder/...
3) Display a hexadecimal dump of said binary file to prove that it is binary...
4) Select a single BYTE of that file and save it as an ASCII text decimal _number_, also to your DEFAULT /directory/drawer/folder/...
5) Read this ASCII text decimal number back in again...
6) Add this string representation to a number...
7) Stop...</p>
<p>It was intended purely for OSX 10.7.5 and above using the default terminal and shell...</p>
<p>It does work on many Linux flavours and shells/terminals also however.</p>
<p>Written so the anyone can understand what is going on.</p>
<p>The two files generated and saved in this DEMO to your DEFAULT /directory/drawer/folder/ are:-</p>
<p>BinaryString.dat
BinaryString.txt</p>
<p>This WILL lead to something very unusual in the not too distant future...</p>
<p>This is Public Domain and you may do with it as you wish...</p>
<p>Enjoy finding simple solutions to often very difficult problems...</p>
