Deadlines and Agility

I was recently asked to engage in a debate over whether or not there are deadlines in agile. There were a few folks involved in the debate and the predominant perspective seemed to be that true agile efforts have no external deadlines - all deadlines are self-imposed by the team in the form of an iteration commitment or a scope negotiation with the Product Owner.

This is bunk.

Comments rarely improve code

Comments rarely improve code

The debate over comments in code is ongoing. At least once per year for the last 30 years, I’ve been involved in a discussion on the subject - often accidentally and reluctantly. To be honest, my perspective has changed over time. I used to comment every method, I used to comment any line of code that was “weird”, and I used to comment any blocks of code that were too complicated. Today, I rarely comment, if ever. Over time, I’ve come to realize that most comments are unnecessary.
