Some recommendations in this one are highly specific (e.g., keeping security clearance as an option) and probably applies to the author's choice of field (something politics in DC) but not (?)most fields. I certainly don't want to work for anyone who requires me to have a security clearance. Everything I've heard about programming in a security clearance environment is a nightmare.

Also, I'm not sure how you get to 30 in software without having a full resume (1-pager, only relevant experience). You don't need 10 10% side projects and you definitely don't need to take unpaid internships.
