I am aggregating here some more or less interesting stuff of various IT related materials which I came across this month. Some of them are strictly related to the things I did or am currently doing.
Some thoughts
git rebase --interactive and fixups
I have seen how different people use Git, and each person has their own way of using it.
However, I did not see many people using git rebase interactive and fixups.
For a long time, I have been thinking about presenting how I use git rebase, git rebase interactive, and my beloved fixups.
A long time ago, I wrote a short blog post about it (Changing history in Git), but I felt it was not enough.
I wanted to show it in action and explain why I do it.
Because of that, I decided to prepare a presentation about it.
I presented it during one of the internal meetings at work, and I think it went well.
I am planning to present it during one of the meetups in the future.
I was a little bit frustrated with Google Slides and how it handles code snippets. I decided to keep the text of the presentation in the repository, so it is easier to track changes, publish and share it. Inspired by Raymond Hettinger I decided to use the documentation generator MkDocs and Material for MkDocs. The presentation is available as a website under my domain: tobked.dev/git_rebase_interactive. Its source is on my Github: github.com/TobKed/git_rebase_interactive.
Google Cloud Developer Day Warsaw 2023
I attended Google Cloud Developer Day Warsaw 2023 on April 27th, 2023. It was a free event organized by Google Cloud at their Warsaw Campus. I wrote more about it in a separate blog post: Google Cloud Developer Day Warsaw 2023.

Saving Energy: Home Server That Automatically Suspends to RAM and Wakes Up Again which is used for Plex media streaming and Time Machine backups.
It does not sound like much, but running a 24/7 home server that draws 43 watts in idle is quiet expensive, considering the latest electricity prices of about 49 euro cent/kWh here in Germany (as of October, 2022). A simple solution to this problem is a script that automatically suspends the server, when it is not used, and another script to wake the server up again, in case there is work to do. To my surprise I could not find any out-of-the-box solution, so I thought, it is a worthwhile effort to write about it.

The age of Agile must end
30 years ago the technology industry attempted to import Lean practices — it failed. Instead of “continuous improvement,” progress halted. Agile is incompatible with UX research, design, and scalable development. It always will be. It’s time to create a new operational standard.

syntactic sugar blog posts by Tall, Snarky Canadian (Brett Cannon)
"In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer." -- https://en.wikipedia.org/wiki/Syntactic_sugar
The different uses of Python type hints
There isn’t really a point of this post other than to say “be aware of these different use cases”. This awareness can be very important when you are in any discussion about the usefulness or necessity of type hints — which scenarios are you thinking about?
A Gentle Introduction to the Python Match Statement
When new features are added to Python, sometimes it can take a while to learn about and start using the feature. For me, the Python match statement (a.k.a. structural pattern matching) is a good example. Some features are very easy to grasp and use (for example, f-strings), but structural pattern matching is a bit more complex.
