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.")

netstat (ss)

Displays contents of /proc/net files. It works with the Linux Network Subsystem, it will tell you what the status of ports are ie. open, closed, waiting, masquerade connections. It will also display various other things. It has many different options. Netstat (Network Statistic) command display connection info, routing table information etc. To displays routing table information use option as -r.

Sample output:

Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)    
tcp4 0 0 127.0.0.1.62132 127.0.0.1.http ESTABLISHED

USB Device ID 1f3a:1000 Allwinner F1E200 electronic postcard

I received a promotional folder that plays a video with sound when opening the folder. This contains a rechargeable LiPo battery, a TFT display, a speaker, a power switch, a push button, 256 MB flash memory, RAM, and a CPU.

All of this for watching one 1-minute video.

What a waste! Certainly not environmentally friedndly. Until repurposed creatively!

On the back it says that the product can be sent back to the manufacturer for free recycling. Still I was wondering if I could do more with it.
