Week 1

  • TODO
    • Create an account on this wiki for yourself (note: requires manual creation)
    • Add your info to the Fall 2014 Open Source Students page.
    • Create a blog (wordpress or blogspot or whatever) and create a feed category or tag called "open source"
    • Read the Blog Guidelines for instructions on how to use your blog in the course
    • Add your blog feed and info to the Open Source@Seneca Planet List so that it appears in the OpenSource@Seneca Planet
    • Pick one Closed and one Open license/EULA, and read them from start to finish. Pick 3 things that struck you, blog about it and your reactions to the readings this week.
    • Begin learning how to use IRC for communication. We'll cover this in detail next week, but it's better to get started early.

Week 2

  • Release 0.1
    • Option 1 (for those new to open source):
      • Implement du in Filer
      • You will learn git, github, JavaScript, node.js, npm, Filer, code review
      • You must fix the bug yourself and have it reviewed by another student *and* review another student's implementation (i.e., do a pull request against another student's fork, and vice versa)
    • Option 2 (for those with more experience):
      • Find and fix a bug in one of the projects listed above which is of an equal size to Option 1
      • Releases 0.2, 0.3, and 0.4 will be like Option 2 for everyone
  • TODO
    • Sign-up for a case study and begin researching and immersing yourself - 2014 Open Source Project Case Study
    • Reading for Wednesday's class: The Cathedral and the Bazaar. Please be prepared to discuss next class.
    • Figure out which option you will do for Release 0.1 and begin working on it.
    • Sign-up for an Open Source Case Study
    • Write an introductory blog post about the case study project you chose, and the project that you will be researching.

Week 3

  • Discussion of The Cathedral and the Bazaar
    • "The Linux community seems to resemble a great babbling bazaar"
    • "Linus Torvald's style of development - Release early. Release often. And listen to your customers."
    • "Every good work of software starts by scratching a developer's personal itch."
    • "Good programmers know what to write. Great ones know what to rewrite (and reuse)."
    • "Plan to throw one away; you will, anyhow (Fred Brooks)"
    • "You often don't really understand the problem until after the first time you implement a solution."
    • "When you lose interest in a program, your last duty is to hand it off to a competent successor."
    • "Treating your users as co-developers is your least-hassle route to rapid code improvement and effective debugging."
    • Linus' Law: "Given enough eyeballs, all bugs are shallow." or "Debugging is parallelizable" and "More users find more bugs...because adding more users adds more different ways of stressing the program."
    • "Somebody finds the problem...and somebody else understands it. And I'll go on record as saying that finding it is the bigger challenge."
      • In the cathedral-view bugs are "tricky, insidious, deep phenomena. It takes months of scrutiny by a dedicated few to develop confidence that you've winkled them all out. Thus the long release intervals."
      • "In the bazaar view, on the other hand, you assume that bugs are generally shallow phenomena - or, at least, that they turn shallow pretty quick when exposed to a thousand eager co-developers pounding on every single new release."
    • "If you treat your beta-testers as if they're your most valuable resource, they will respond by becoming your most valuable resource."
  • TODO
    • Install git http://git-scm.com/
    • Create a Github account if you haven't already
    • Fork and clone Filer and start on Release 0.1 if you haven't already (due in 2 weeks). Blog about your progress, what you learned, what you still need to learn
    • Read chapters 1 & 2 of Pro Git, be ready to discuss next week.
