Reading Bill Coughran

Bill was once leading Google's Engineering team and he has many interesting perspective in his sequoia profile linked above.

For example, (you do not need a lot of engineers) the best team is 2 to 8 people in the same room, and a team with good people can steer themselves.

Bill stayed in Bell labs for 20 years, and he thought he should left sooner. Change every few years is healthy.

After a long break, I find it compelling to start writing again, and not limit myself to programming competition or interview problems.
