Colored Rectangles

2016-01-30, post № 102

This program lets you spawn in a rectangle with a randomly assigned color. This rectangle will then slowly move towards the screen’s edge, eventually fading away.

Controls

  • Left click spawns in a new rectangle at current mouse position,
  • ‘Space’ takes a screenshot.

Moving Fonts

Experimenting with Pygame’s font functions, I wanted to list every font Pygame could reach with its built-in font.get_fonts() function. This program does so by letting you spawn in the wonderful sentence ’Hello world.’ and assigns it a font based on the previously mentioned function.

Controls

  • Left click spawns in a new sentence at current mouse position,
  • ‘Space’ saves a screenshot.

The Hundredth Post

2016-01-16, post № 100

The J-Blog has reached its hundredth post, this one. It being the hundredth post, I want to review my previous posts. But rather than going into the context of my previous 𝟫𝟫 posts, I decided to write a program to do this for me.

The program goes through a list fetched from my Table of contents page, looks up the html code, distills the post and counts how many characters of each type there are. [1] It then outputs its results in a nice text-based style (can be seen below).

To further visualize the data, I wrote another program to display it graphically. The results look like this. On the left the characters are sorted alphabetically (ASCII) and on the right they are sorted by occurrence (you may click on the images to view them closely).
