I'm usually sure I'm not "right" about how to build software. Sometimes I even suspect there is no right answer to a lot of software engineering questions. For example, I always get a funny (unpleasant) feeling in my stomach when I here the phrase "best practices" in the context of software engineering. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
