Don’t use “kill -9”

In the past, any time I wanted to stop an errant process on unix, I just used “kill -9”. By default. Without thinking about it much.

Then a colleague commented to me that you should never use kill -9. It terminates the process with no chance to shutdown in an orderly manner, and so can leave things in a bad state, such as corrupting files. “But what else am I supposed to do!?” I naively asked.

There are of course many other options for the kill command (see links below), but here are some alternatives you can try, in the order you may want to try them.

Continuous integration / Continuous Delivery / Continuous Deployment

The terms Continuous Integration, Continuous Delivery and Continuous Deployment can still confuse. Even Jez Humble, author of the book Continuous Delivery commented that there is “confusion around the terms continuous delivery versus continuous deployment and my own thinking and definitions have changed”.(1)

What Is Agile?

Agile software development is an approach to developing and delivering working software into production in incremental, iterative work cadences, known as sprints.

Being ‘agile’ is more of a philosophy than a set of rules. It is a mindset to continually improve; to embrace new ideas and implement the best ones, testing in the wild all the while to find what really works. Collaboration, feedback and iteration are key.

In this post, I will briefly touch on the Agile Manifesto where it all started, before looking at some basic concepts (feedback) and alternatives (waterfall), before the main bulk of the article, which is the flavors of Agile, including XP, Kanban and, primarily, Scrum.
