After read this post, I chose try do this too. But have some rules to be followed.
• I must write code every day. I can write docs, or blog posts, or other things but it must be in addition to the code that I write.
• It must be useful code. No tweaking indentation, no code re-formatting, and if at all possible no refactoring. (All these things are permitted, but not as the exclusive work of the day.)
• All code must be written before midnight.
• The code must be Open Source and up on Github.
And you will try too?
