Editor's Notes
- #3 Title insignificance – best compliment is great programmer
- #5 Agile is about constant change and such cannot happen without clean code World of constant change – requirements, product, people – clean code makes it easier to adapt
- #6 Interwise – acquired in 2007 Main Interest: Telecommunication applications, now also big data
- #7 Design: templates, patterns, reviews Coding: standards, review, static code analysis Unit testing: methodology, coverage, execution
- #9 Q: how often do you do it? Term first introduced in 1990, by 1992 was used in context of OOC Personally only heard in in the late 2000’s – beforehand - rewrite
- #10 Q: what tools do you use Aiding tools: IntelliJ, Eclipse, Resharper, CodeRush
- #11 Invest when you can – use when you have to Code rots over time Debt has deficit Too much will lead to bankruptcy
- #12 * Expectations vs. Actual
- #13 No valid excuses (what happens when I skip it) Harder to submit to one
- #14 So we’ve got refactoring and Code Review, how do they play with Agile dev? In the short term it takes longer to write clean code (Churchill)
