Two of the most important are practical strategies that good programmers use and where to go to find answers to questions that arise while you are programming. Using a couple of brief narrative case studies, we'll look at how programmers find solutions to problems. Appendix A lists some of the best Perl and bioinformatics resources to help you solve your particular problems.
