Historically, the Python syntax hasn’t had a switch-case statement. In 2006 Guido van Rossum, the original author of Python, proposed different alternatives for the switch-case syntax in PEP 3103 but they all seemed to have some problems and the idea didn’t gain enough popular support. The proposal was therefore rejected. Python version 3.10 changes this.

In the Flow
Janne Kemppainen |
I’ve been investigating different methods of personal note management, and I’ve come to the conclusion that I want to keep my notes as plaintext Markdown files for the best future compatibility. One of the tools that I’ve been trying out is Obsidian. At some point I will probably write a comparison of the different software I’ve been trying out, but this post is actually about getting into the flow state of writing.
Manage GCP Resources with GitHub Actions

You can manage Google Cloud resources pretty easily with the gcloud command-line tool, but automating that stuff can be even more fun! In this post we’ll see how to use GitHub Actions to perform actions on GCP.
Move a Git Tag

Normally when you create a Git tag you should just let it be and not alter the history after the fact. But if you really need to move a tag forward how can it be done?
Create Self-destructing VM Instances on Google Cloud
Janne Kemppainen |
When you run temporary workloads you may not want to leave old machine instances lingering behind. Preemptible VM instances let you run at a significantly discounted price but they are shut down automatically after 24 hours, or earlier if Google needs those resources. The instances will still remain there in shut down state and they can still be turned back on later. What if you wanted to delete the machines automatically when you’re done with them?
Do More with Workflow Commands for GitHub Actions
Janne Kemppainen |
If you’ve read my Gentle Introduction to GitHub Actions you should already have a good understanding of the GitHub Actions basics. Creating a workflow is usually quite simple as long as you can find suitable action implementations for your steps. In some cases you may need to write your own actions, but you can actually get quite far with workflow commands.
Return Many Values as Attributes in Python
Janne Kemppainen |
When you need to return complex data from a function you typically think of two options:
- put the values in a dictionary
- create a new object/class
The first option is simple to implement but you need to access the individual values by their keys. The second option allows you to access data via attributes and do custom calculations behind the scenes, but then you need to implement yet another class.
Is there something in Python that could give us easy attribute access without having to bother with custom classes?
Import ES6 Modules in Node.js

With the ECMAScript modules definition we can use the import and export keywords to load and publish library code. However, if you try to use them in your Node.js project you might encounter the following error:
GitHub Actions Repository Dispatch
Janne Kemppainen |
There are lots and lots of events that can be used to trigger GitHub Actions. But if you want to control your actions programmatically from the outside you will need to use repository dispatch. In this post I will go through the essential things you need to know to trigger actions programmatically.
Schedule Netlify Builds with GitHub Actions
Janne Kemppainen |
Would you like to be able to schedule the blog posts for your static site into the future but don’t want to use up all of your free Netlify build quota? In this post we’ll create a GitHub Actions workflow that triggers a site rebuild when a post has been scheduled to be published.
Define a Python Script Inside a GH Actions Workflow File
Janne Kemppainen |
GitHub Actions gives you lots of freedom to define custom workflows by combining different actions and running command line programs. Sometimes you might want to run small snippets of code, and that is already possible by running scripts from the command line with the run keyword. What if you could write your Python script inside the workflow YAML file instead?
Dynamic Attributes in Python
Janne Kemppainen |
When you define an object in Python you usually give it some attributes that hold the necessary pieces of information in a place that makes sense. However, Python does not limit the use of attributes to the set that were described at object creation time.
