  3. Tricks & tips • Debugging hint #1: • “Stop thinking and look.” -- D. J. Agans • Huge amount of time taken up in debugging • Often, much/most of debugging time spent working on the wrong thing • Key to working on the right thing: actually look at what’s going wrong • Most basic way to do that: print statements • Painful, slow, basically sucks • Much better: find, learn, and use a good debugger

  4. Group design exercise • Design and give pseudocode for the web crawl traversal algorithm • Don’t worry about network I/O or HTML parsing • Focus on: • Hitting every reachable page once • Not hitting any page more than once • Efficiency: small overhead per page • Can assume methods • WebPage retrievePage(String) • String[] getAllURLsInPage(WebPage) • (Or your favorite others)
