This is really a timeless piece of very valuable information to any programmer.
Still, there is something i would like to add, from my personal experience:
Item 9., “Don’t be the coder in the corner” - while i think this is true, to an extent, it shouldn’t give people shame if they sometimes perform better when coding alone. Don’t put yourself in a position of unease for extended periods, just because you understand some 10 commandments of egoless programming that way. This should not be always, but in some task or project, i need to take my time to come up with a good solution, and while any solution should always be presented (and defended if necessary, and adapted from external input if necessary), sometimes it can be better to take your time with it, because of the other egos that might influence a solution to the worse, when doing so prematurely.
When you are an experienced programmer, you are your own worst critic, so make use of your strengths, know your strengths and don’t let people tell you otherwise. Let the results speak for themselves.
It always depends on the environment, but it should be your call to choose the right approach. You are the expert.
