The way developers somehow think DevOps is (or should be) an abbreviation of "Developers doing/replacing Operations" is terrifying to me.I'm also in the same boat as the author, in that I recommend and target Debian Stable + Backports (and some vendor/community repos when required).
However hard you work on documentation, it won't work for your software - unless you do it the right way.
I'm going to preach the wonders of Python dataclasses, but for reasons of interested to those who have already gone down the delightful rabbit-hole of typed Python. So let me start with a quick plug for mypy if you haven't heard about it.

A good explanation of the three level of "stopping" a service in systemd, with a focus on masking.
«For a long time I’ve wanted an ssh-agent setup that would ask me before every use, so I could slightly more comfortably forward authentication over SSH without worrying that my session might get hijacked somewhere at the remote end (I often find myself wanting to pull authenticated git repos on remote hosts). I’m at DebConf this week, which is an ideal time to dig further into these things, so I did so today. As is often the case it turns out this is already possible, if you know how.»

Jacob Kaplan-Moss is known for his work on Django but, as he would describe in his keynote, many think he had more to do with its creation than he actually did. While his talk ranged quite a bit, the theme covered something that software development organizations—and open source projects—may be grappling with: a myth about developer performance and how it impacts the industry. It was a thought-provoking talk that was frequently punctuated by applause; these are the kinds of issues that the Python community tries to confront head on, so the talk was aimed well.

«Why are there so many more undocumented systems than documented ones out there, and how can we cause more well-documented systems to exist? The answer isn’t “people are lazy”, and the solution is simple – though not easy.»

«Developers can get better at their craft by learning from the great writers who mastered theirs. Writing software isn’t the same as writing a novel, but there are parallels. Besides, advice from writers is better because writers have been struggling with their craft for many centuries, not just a few decades. It’s better-written as well. This talk shares great writers’ best advice for coders: Stephen King on refactoring, Anne Rice on development hardware, Hemingway on modelling with personas, and Neil Gaiman on everything.»
