Just a general logo design idea I had, but I really do love the tech scene in the San Francisco Bay Area. I’m not sure if this design is original.

Axelrod’s “The Evolution of Cooperation” delivers ideas that are at the same time obvious but surprisingly insightful to human nature. It is a small and readable book which every chapter left me thinking, “Of course, why didn’t I think of it like that?”

If you don’t know Lua, the popular programming language often used as a embedded scripting language, but you do know how to program, here’s a cheat sheet that covers the basics of the language’s syntax.
The cheat sheet itself is an executable program. You can download the file here: lua_cheat_sheet.lua
For quick viewing, here it is on […]

I got tired of not having a good cross-platform module for accessing the clipboard in Python, so I put this together. It is a module that loads a copy() and paste() function depending on what your operating system (or window manager) is.
