== Week 3 ==
 
* Discussion of [http://www.firstmonday.org/ojs/index.php/fm/article/view/578/499 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."
 
* Release 0.1 - Getting Started
** Case Study: implementing [http://pubs.opengroup.org/onlinepubs/7908799/xcu/wc.html wc]

**** Look around the code you're writing
**** Look for similar patterns in other files
**** Use <code>git blame</code> and Github Search, find and read commits that added similar code
**** Copy/Paste/Modify
