Andrés Taylor has written an insightful list of the "Top ten things ten years of professional software development has taught me" but don't be fooled this is a very good list with relevant items for anyone working in IT and not just developers.
I particularly like the fact that Andrés has recognized the importance of communication even for developers.
About Dave Mellors
I work for Red Gate Software in Cambridge, UK as part of the technical services team. This is my personal blog and so carries my own personal views which could vary from the views and opinions of my employer.
I am passionate about IT and would like to change the way that people think about the IT industry and the people that work in it. Particularly those who work in the support teams.
