Open-Source Bioinformatics Programs?

An anonymous reader asks: "This summer I have the opportunity to work in a bio research lab creating a web site for data about proteins. Part of my job is to do bioinformatic analysis of the proteins to determine what types of support their are for the preliminary gene predictions. I have been using DNA Stryder (a Mac program) for sequence alignments plus translations from DNA sequences to protein sequences, and I was wondering if any of the Slashdot crowd knew of similar programs for Linux? I have looked into Bioperl , Biopython, EMBOSS, and BioConductor, but they seem to be more oriented towards servers and less towards stand-alone applications. What programs would you suggest, especially those that might be geared more towards biologists rather than computer scientists?"
