Don’t fall for the golden hammer: avoid git empty commits, especially for kicking off parts of your CI/CD

Posted by jpluimers on 2022/08/16

A while back Kristian Köhntopp (isotopp) wrote a blog post after quite a Twitter argument where he poses against using git empty commits. I’m with Kris: don’t use them for anything, especially not for kicking off your CI/CD.

Basically his blog post is all about avoiding to think you have a golden hammer, and avoid falling for the Law of the instrument – Wikipedia.

Originally, Abraham Maslow said in 1966:

“I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.”

For me this has all to do with preventing technical debt: find the right tool to kick your CI/CD pipeline after part of that chain somehow malfunctioned is way better than polluting the commit history with empty commits.

His blog post: [Wayback/] Empty commits and other wrong tools for the job | Die wunderbare Welt von Isotopp

The most important bit in it:

And since we are talking about CI/CD pipelines: Don’t YAML them. Don’t JSON them. Don’t XML them.

Programming in any of these three is wrong use of tooling, and you should not do it.

  • YAML, JSON and XML are for declarative things.
  • Python, Go and Rust are for procedural things.
  • Bash is for interactive use only.

Use the proper tooling for the job. Be an engineer.

This very much reminds me of an Entwickler Konferenz keynote a long time ago, where Neal Ford made the point that most software engineers act very much unlike what is expected from traditional engineering way of operating where the engineer is both responsible and liable for his actions.

The start of the Twitter thread: [] Kristian Köhntopp on Twitter: “A lot of people right now that git is an API and triggering CI/CD pipelines with empty commits replaces the equivalent of a Kubernetes controller for their fragile pile of bash in git triggers. This is broken and begets more brokenness. Evidence:… “

The tweet that started the subtweet: [] Florian Haas on Twitter: “(For anyone wondering, what’s nice about this one is it works in any CI. So you don’t have to remember how to manually kick off a GitLab CI pipeline or GitHub Action or Zuul job, you just push an empty commit and off you go.)”

Other relevant tweets:

Yes, you want to avoid shell too (anything like for instance sh, ash, dash, bash or zsh), but you have to know it (and understand why to avoid it) as often it is the only interactive way to access systems from the console.

And of course Kris also wrote a big document on that too, which is available as full PDF (Wayback), full HTML (Wayback) and chaptered HTML Die UNIX Shell /bin/sh.

But more importantly, Kris wrote [Wayback/] Using Python to bash | Die wunderbare Welt von Isotopp which is about using Python to do things you might be tempted to do in the shell. It quotes

Shell is a thing you want to understand and then not use, because you learned to understand it.

which is from the German post in thread [Wayback/] Bashprogrammierung, wo gehts am besten los which quotes Kris’ 1998 message:

Verwende Perl. Shell will man koennen, dann aber nicht verwenden.

Powershell code formatting and coding style and style guides: some links and elaboration

Posted by jpluimers on 2022/07/05

I started doing occasional PowerShell “work” long before Visual Studio Code came along with its [Wayback] PowerShell Extension.

Back then, my tool of choice was PowerGUI: Settling on PowerGUI for PowerShell development. Before that it was PowerShell ISE.

Since then, I fiddled around a bit with Visual Studio Code, but not much. Then I got treated for rectum cancer, and when writing this, I’m back to Visual Studio code with the PowerShell Extension and already figured out a lot has improved.

One of the things is code formatting. Back some 7 years ago, this was all not set in stone. Now it is, so it is important to adhere to.

I already posted Code Layout and Formatting: Indentation · PowerShell Practice and Style last year, so now it is good repeat the link in it and add some more.

For my link archive:

Attacking Technical Debt – ardalis

Posted by jpluimers on 2021/08/12

Interesting approach in [WayBack] Attacking Technical Debt – ardalis.

The tech stuff is C# and .NET based, but the general approach can be applied in a universal way.

via: [WayBack] Jim Holmes on Twitter “Great post by @ardalis on attacking Technical Debt. … You should also read my series on creating a Technical Debt Payment Plan, starting here: …”

So also read

Technical debt: “taking shortcuts leads to long-term bleeding…”

Posted by jpluimers on 2019/07/19

From a while ago:

Just tried to explain technical debt: “taking shortcuts leads to long-term bleeding.”
