By popular request - here's the script I've been using to plot histograms of the comparative frequency distribution of data using Python.

This script takes a list of any size, where the contents are tuples containing a list of floating-point data, and a name for that data.

For example:

...
# copy or import the plotHistogram script here.

Here's my implementation of a BubbleSort algorithm in Python.
I've also taken the opportunity to update my C and PHP BubbleSort Gist from a few years ago.
This was written using Python 3.8.10.

Here's my implementation of a SelectionSort algorithm in C and Python.
It's fairly verbose and easy to read, but could probably do with a cleanup at some point. The C version was written using GCC 9.3.0, and the Python version was written using Python 3.8.10.

Depth-First Filesystem Traversal in PHP

Whilst working on BlogDraw-Updater earlier this week, I created a nifty little system for filesystem traversal in PHP which I thought I'd share with you all because it might be useful. At the very least, it could save a couple of people some time writing something like this out themselves.

It uses depth-first traversal to locate every file in a filesystem, implemented through a recursive function (traverse). "traverse" takes a filepath (either relative, or absolute) to a directory and locates all files and directories within it. It also locates all files and directories in those directories, and so on until it's mapped out the entire filesystem.

Conventions

I've chosen to demonstrate a couple of unusual conventions here, namely:

#include <stdio.h> /*Standard I/O Library*/
#include <stdlib.h> /*Standard Library - Handles EXIT_SUCCESS*/
#include <stdbool.h> /*Standard Boolean Library*/

int data[] = {21,2,3,4,10,6277,71,948,8,140};

Some Basic JS Accessibility Tools using jQuery

I've had this code lying around for a while now, and I only really use it on one website, because most people that need it have software that can do it for them. I thought other people may find it more useful than I do. So, feel free to use it.

The Code

• accessibility.html, this contains the two buttons I use for increased accessibility. It also calls jQuery's CDN (but you can use locally hosted jQuery if you want), and it calls the accessibility.js script.
• accessibility.js, this contains a jQuery event handler for each button, containing an anonymous function to handle the button's intended operation.
