Welcome to the twelfth issue of De Programmatica Ipsum, dedicated to the subject of Being a Senior Developer. In this edition Daniel Steinberg explains how forty years of experience in the field is just the beginning, Graham argues that "agile" methodologies have reached senior status at the age of twenty, and in this issue's subscriber-only article, Adrian talks about not being a senior developer anymore.

About ten years ago there seemed to be a slew of thirty year olds explaining what it was to be old. “Now that I am thirty,” they would say, “I understand …” I am not sure what it was they understood. I had stopped listening and faded off into my own head thinking, “uh oh, what if they find out I am fifty. They will never hire me.”

Agile won. The practices encouraged by Agile transformation coaches the world over are practiced the world over. I do not remember a software team in the last decade who did not gather around for their regular standup meeting. A team who did not drag Jira stories across a board, in standard "as a user" format. Who did not have Jenkins builds kicked off by every commit. Who did not ignore, if not actively block, attempts to explain how their software worked with long sentences and UML diagrams. Or maybe Agile lost.
