This is a motivational talk about practicing programming skills as a professional programmer. I gave the talk many times in many conferences and companies.
You can find the video of me giving the talk on this here (in Chinese): http://v.youku.com/v_show/id_XMzI3OTI1MDQw.html
I did the talk in English as well, but there's no video online.
Clipping is a handy way to collect important slides you want to go back to later.
