Generate a PDF cheat sheet for converting 0 to 255 between bin / oct / dec / hex (Python)

2016-10-10T20:40:48-07:00

Python recipe 580706 by Vasudev Ram (binary, conversion, decimal, hexadecimal, octal, pdfwriter, pdf_generation, python, utility, xtopdf).

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.

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.

A binary file split utility in Python (Python)

2016-04-07T18:19:35-07:00

Python recipe 580637 by Vasudev Ram (binary, commandline, linux, python, unix, utility, windows).

This recipe shows how to create a simple binary file split utility in Python.

It takes two command line arguments: 1) the name of the input file to split , 2) the number of bytes per file into which to split the input.

Catalog multiple drives (Python)

2016-03-11T03:39:32-08:00

Python recipe 580619 by Jack Trainor (drives, files, utility).

As one accumulates multiple drives, hard and flash, containing, thousands even millions of files, it becomes useful to have a text file containing an alphabetized catalog list of all files and their locations by drive and directory.

The list can be searched by eye or by an editor to locate particular files.

The list can also be loaded into a script to be filtered programmatically as desired.

data_dump.py, like the Unix od (octal dump) command (Python)

2015-11-01T12:43:38-08:00

Python recipe 579120 by Vasudev Ram (data, dump, hexadecimal, linux, octal, od, representation, unix, utility, windows).

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.

CSV to Flat File Converter (Python)

2015-08-02T17:31:59-07:00

Python recipe 579091 by FB36 (csv, files, utility).

'Which' for Windows (Python)

2013-08-16T09:14:07-07:00

Python recipe 578642 by Robert Pyron (commandline, python, utility, which, windows). Revision 2.

WHICH.PY scans through all directories specified in the system %PATH% environment variable, looking for the specified COMMAND(s). It tries to follow the sometimes bizarre rules for Windows command lookup.

Countdown Timer (Python)

2012-12-06T03:24:35-08:00

Python recipe 578363 by Stephen Chappell (demonstration, sound, timer, utility).

Ever wanted to set a timer that went off after a specified number of hours / minutes / seconds? This Windows recipe runs on the command line and does that with the arguments it accepts. Simple but effective, the program works well for remembering food in the oven among other things.

Directory Pruner 4 (Python)

2012-06-06T22:00:00-07:00

Python recipe 578154 by Stephen Chappell (delete, directory, file, gui, utility). Revision 2.

Module providing GUI capability to prune any directory.

The code presented in this module is for the purposes of: (1) ascertaining the space taken up by a directory, its files, its sub-directories, and its sub-files; (2) allowing for the removal of the sub-files, sub-directories, files, and directory found in the first purpose; (3) giving the user a GUI to accomplish said purposes in a convenient way that is easily accessible.

Custom Windows Alarm Clock (Python)

2012-07-10T17:27:48-07:00

Python recipe 578204 by Stephen Chappell (alarm, archive, clock, old, utility).

After writing a few alarms using winsound.Beep, desire to expand into other sound possibilities led to the writing of this program using winsound.PlaySound. The sounds are stored in a custom format (some experimentation in archiving files). This is committed for archival to be run under Python 2.5 or later versions.

Zero (Batch) Programs (Python)

2012-07-10T12:37:37-07:00

Python recipe 578205 by Stephen Chappell (archive, batch, old, processing, utility). Revision 2.

Having written many programs that work with groups of files, the zero programs were written based on a simple batch engine in the zero utility. All of the other programs import the first program to take advantage of its batch processor while supplementing there own functionality in place of zeroing out file data. This is committed for archival to be run under Python 2.5 or later versions.

Setting Namespaces (Python)

2012-07-05T02:39:42-07:00

Python recipe 578195 by Stephen Chappell (helpers, library, options, utility). Revision 2.

Provides a simple way to deal with program variable versioning.

This module defines two classes to store application settings so that multiple file versions can coexist with each other. Loading and saving is designed to preserve all data among the different versions. Errors are generated to protect the data when type or value violations occur.

Linux to Windows (Python)

2012-07-04T01:18:50-07:00

Python recipe 578192 by Stephen Chappell (archive, commandline, old, utility).

When trying to work with Linux archive downloaded onto Windows, sometimes it is helpful to untar all found archives, give extension-less files the "txt" extension, and convert text files to Windows line endings (\r\n), and that is just what this program is designed to accomplish. This is committed for archival to be run under Python 2.5 or later versions.

Settings Organizer (Python)

2012-07-04T22:16:36-07:00

Python recipe 578173 by Stephen Chappell (helpers, library, options, utility). Revision 3.

Provide an easy method to manage program options among multiple versions.

This module contains two classes used to store application settings in such a way that multiple file versions can possibly coexist with each other. Loading and saving settings is designed to preserve as much data between versions. An error is generated on loading if saving would lead to any data being lost.

Directory & File Counter (Python)

2012-07-07T22:07:51-07:00

Python recipe 578197 by Stephen Chappell (archive, old, utility).

This recipe manually counts the number of sub-directories and files can be found in a directory. It was an experimental program from long ago used to learn more about Python. This is committed for archival to be run under Python 2.5 or later versions.

Rookie's Backup Program (Python)

2012-07-08T00:52:05-07:00

Python recipe 578199 by Stephen Chappell (archive, copy, old, utility).

A while back when still fairly new to Python, this simple program was developed to back directories of information. In reality, it is just a simple (and poorly written) file copier that could be greatly improved. This is committed for archival to be run under Python 2.5 or later versions.

Just Another Password Generator (Python)

2012-06-21T15:41:10-07:00

Python recipe 578171 by Stephen Chappell (password, passwords, password_generator, utility).

The following two programs are simple examples of how one might go about creating a password generator. The first one was created several years ago and was designed to return passwords where similarly classed characters would not appear beside each other. It works but gets unbearably slow when passwords exceed about forty characters. The second program was designed with similar requirements runs considerably better. Eight-character passwords appear to have the same randomness to their construction, and this program is considerably faster than the first. Hopefully, these program design differences will be helpful to others trying to write their own password generator.

Markov Encryption Module (for Python 2.5) (Python)

2012-07-25T22:33:03-07:00

Python recipe 578135 by Stephen Chappell (encryption, library, module, utility). Revision 4.

This module provides classes that are useful for executing Markov encryption and decryption on data. ME was inspired by a combination of Markov chains with the puzzles of Sudoku. This implementation is a rewrite from the Python 3.x version and includes various changes and optimizations to work with Python 2.5 and related versions. All documentation has been left in recipe 578075 and should be referred to there.
