How to Mutate a Float (Python)

2012-05-14T16:49:13-07:00

Python recipe 578132 by Stephen Chappell (ctypes, experiment, float, structure).

This is just an experiment to test my mental understanding of Python. It should not be used in any code as is violates the design principle that floats are to be immutable. The code also abuses ctypes and an understanding of how floats are currently arranged in memory. set_float is not guaranteed to work properly on any system, and may fail to work in the future if the data's arrangement changes.

processing (Python)

2012-01-09T02:23:35-08:00

Python recipe 578004 by Stephen Chappell (experiment, framework, gui).

This module was inspired by http://processing.org/ . The code is meant to mimic an extremely small subset of this high-performance library. After seeing how easy it was to accomplish certain task in the Java framework, a desire was created to have a simple starting point to create little graphical experiments that would be easy to program without haveing to know a lot of details regarding setup, timing, et cetera. This is the result of that desire.

Morse Code (Python)

2012-01-12T23:45:12-08:00

Python recipe 578012 by Stephen Chappell (demo, demonstration, example, experiment, morse, morse_code, program, sound). Revision 3.

After seeing another recipe recently that helps people with Morse Code, I was inspired to clean up the following code just a bit to make it worthy for the rest of the world. After being executed, it waits for lines of text to be entered, compiles each one in turn into timing codes, and plays them back with a simple execution

Rudimentary Database Engine (Python)

2013-09-02T01:51:53-07:00

Python recipe 577825 by Stephen Chappell (database, engine, example, experiment). Revision 2.

This module was written for self-academic purposes in an attempt to understand databases better. Just as in college where students are required to reinvent "wheels" like linked lists, trees, binary searches, et cetera, developing this program helped me understand some of the things that goes on behind the scenes in a database while also helping to learn what the desired output of each operation should be. The code in this module provides support for running a simple database engine that runs completely in memory and allows usage of various concepts available in a structured query language to get and set data that may be saved to file.

Bitmap Maker (Python)

2011-04-21T13:08:46-07:00

Python recipe 577674 by Stephen Chappell (experiment, generator, images, proof_of_concept, test).

A friend and I were discussing the possibility of creating every possible image that is 800x600x24 (800 pixels wide by 600 pixels tall and using 24-bit color). This recipe is a proof-of-concept program showing what is possible with just a 2x2 image using 15 different colors (yielding a total of 50,625 images when run). In terms of the original thought experiment, a total of 16777216 ** 480000 images should be possible given the 800x600x24 specifications (or 1 << 11520000 in binary). In base 10 that is 10 ** 3467865.55 and shows that there are an enormous number of possible states that a 800x600 canvas can take.

Color Study 1 (Python)

2011-04-05T23:35:32-07:00

Python recipe 577636 by Stephen Chappell (color, example, experiment, gui, sandbox).

The following program was written to understand how two different color systems related to each other, RGB and HSV. The recipe could be better written and extended further to support other color systems in addition to the two it already uses, but it is a simple example of how one might go about to understand what others speak of when talking about color. The GUI is simple to use and responsive, and the code is a good demonstration of what may need to be written to produce a demonstration such as this one.

If you have suggestions or would like to vote this recipe down, please provide an explanation of the problem along with a solution that you would propose and implement to improve upon what is presented.
