Question: A book full of examples of how NOT to write perl . I couldn't resist the title, so I got this book. Unfortunately, I cannot reccommend it to people who want to learn to write better Perl, execpt as a source of examples of the mistakes you should avoid.    For example, in one of the earliest examples, the authors uses "return undef" in a situation where the return value of the routine is assigned to an array, to indicate the routine didn't find any of whatever it was looking for.

Appleby has a remarkable feel for the politics of the early Republic, and does a brilliant job of recreating for a modern reader exactly what the Federalists and the Democratic-Republicans were fighting over.  She makes a strong case that Jefferson stood for democracy, against elitist opponents who sought to exclude common people from voting.    The core of her argument is that Jeffersonian republicanism is at the heart of our modern conception of democracy, and that both contemporary political parties -- the Democratic and the Republican -- draw equally on his legacy.  An important argument to remember in these partisan times, and it gives us hope that we can overcome our current profound divisions
