You might like to check out my Labradoc site which is designed to make it easier to create project/dev logs: http://labradoc.com/

Here's an example of a project log for a current project I'm working on: http://www.labradoc.com/i/follower/p/notes-qualcomm-apq8060-...

My style is more verbose than Carmack's but Labradoc can be used with either approach.
