Developer tip No. 3: Not six months, not 10 years

Don't switch jobs every six months. Seriously, the end of 100 percent developer employment will come again. When that time arrives, nothing will haunt you more than job-hopping. On the other hand, don't stay at the same place doing the same thing for 10 years. You'll become insulated and institutionalized. To stay valuable, you have to be familiar with more than how to code IBM's stack while at IBM in the IBM way. I haven't hired anyone who was at IBM or a similar organization for more than a year or two. They usually impress me in the interview but fail the programming test.
