Using websockets to easily build GUIs for Python programs

I recently built a small agent-based model using Python and wanted to visualize the model in action. But as much as Python is an ideal tool for scientific computation (numpy, scipy, matplotlib), it's not as good for dynamic visualization (pygame?).

You know what's a very mature and flexible tool for drawing graphics? The DOM! For simple graphics you can use HTML and CSS; for more complicated stuff you can use Canvas, SVG, or WebGL. There are countless frameworks, libraries, and tutorials to help you draw exactly what you need. In my case, this was the animation I wanted:

(Each row represents a "worker" in my model, and each rectangle represents a "task.")

How to use Tim Pope’s Pathogen

I’ll assume you are on Linux or Mac OSX. For Windows, replace ~/.vim/ with $HOME\vimfiles\ and forward slashes with backward slashes.

The idea

Vim plugins can be single scripts or collections of specialized scripts that you are supposed to put in “standard” locations under your ~/.vim/ directory. Syntax scripts go into ~/.vim/syntax/, plugin scripts go into ~/.vim/plugin, documentation goes into ~/.vim/doc/ and so on. That design can lead to a messy config where it quickly becomes hard to manage your plugins.

This is not the place to explain the technicalities behind Pathogen but the basic concept is quite straightforward: each plugin lives in its own directory under ~/.vim/bundle/, where each directory simulates the standard structure of your ~/.vim/ directory.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
