Agile: In A Flash is a great source of software engineering tips regardless if you’re planning to go agile or not.
Out of the many flash cards in that site, I find the two cards above to be the most important to a novice software developer. It should make them feel less surprised when Brook’s Law or Hofstadter’s Law hits them from out of nowhere.
Sadly those cards didn’t make it into the deck (reason: not strictly agile) but the deck was released on Jan 20, 2011. They are available from the publisher (http://pragprog.com/news/agile-in-a-flash-cards) or any of the usual outlets (Amazon, O’Reilly, Borders, B&N, etc).
Hopefully you’ll find the deck useful even without the “great laws.”
