Hello, World!

This blog now supports AsciiDoc content via the Asciidoctor toolchain. Syntax highlighting is provided by Asciidoctor Chroma, which integrates seamlessly with this setup.

Code Examples

Here’s a Python function demonstrating basic syntax:

def fibonacci(n):
 """Generate Fibonacci sequence up to n terms."""
 a, b = 0, 1
 result = []
 for _ in range(n):
 result.append(a)
 a, b = b, a + b
 return result

print(fibonacci(10))

Advanced Features

AsciiDoc supports various features:

Bold and italic text
Inline code snippets
Tables, admonitions, and more

Least Privilege in GitHub Actions

Fri, 14 Mar 2025 11:00:00 +0000

In GitHub Actions it’s possible to remove all permissions from the token at the workflow level and then assign them on the job level:

name: Release
permissions: {} # No permissions

on: 
 push: 
 branches: 
 - main 
jobs:
 release:
 permissions: 
 contents: write
 packages: write
 id-token: write

Microdata

Sat, 08 Mar 2025 11:00:00 +0000

Microdata enables it to describe Metadata in HTML and give a meaning to the markup. That’s handy for Crawler or other integrations. For instance, can an E-Mail render a “discount” (or something else) in the client.

<div itemscope itemtype="http://schema.org/DiscountOffer">
 <meta itemprop="description" content="20% off" />
</div>

A deep dive into DNS

A deep dive into DNS is not a “tutorial” on DNS but good material on getting to know some interesting details about DNS.

A (Relatively Easy To Understand) Primer on Elliptic Curve Cryptography

Mon, 13 Jan 2025 16:50:13 +0000

A (Relatively Easy To Understand) Primer on Elliptic Curve Cryptography gives a great overview of how elliptic curves and how they are used in cryptography. I will probably never understand the details, but this gives me enough information to build a reasonable mental model

Azure CLI stuck

Mon, 13 Jan 2025 09:05:08 +0000

From time to time, my Azure CLI is stuck in the phase urllib3.connectionpool: Starting new HTTPS connection (1): login.microsoftonline.com:443 traced with the --debugflag. Disabling IPv6 solves the issue.

Supernotes

Sun, 12 Jan 2025 20:34:04 +0000

For several years I’m searching for a nice note-taking solution for my personal use. I feel like my requirements are pretty low with:

Multi-Device sync
Markdown Bailout
Web and Android Support
Good UX, simple to use

Yet, I haven’t found one to this day. Now I’ve found Supernotes and giving it a try. In fact, this part of my blog is now driven by Supernotes Cards. On a daily basis a GitHub Actions workflow is running a script which is fetching all note cards with #random and #blog tags and storing them in the Git repository driving this blog. Let’s see how it evolves over time.

GNOME now has default shortcuts for switching between applications. Therefore, the Toggle in the “Dash to Dock” extension to disable shortcuts does not work. To disable them, use the command:
```
for i in {1..9}; do gsettings set org.gnome.shell.keybindings switch-to-application-$i "[]"; done
```

Project Valhalla seems to be finally tangible to reach. Brian Goetz did a few talks on Devoxx Belgium and the JVM Language Summit. I’m pretty impressed by the little complexity “leaked” to the developer.

Today, by watching this video, I learned about the Polish notation and Reverse Polish notation which are pretty important concepts for the invention of our current computing model using stacks. With the polish notations we can formulate a mathematical/logical expression without the need for parentheses by placing operators in front (or behind) the operands.
Google published a paper about mercurial cores. Basically, as a Hyperscaler they observe their CPUs are miscalculating operations sometimes due to e.g. manufactoring issues. This issue occurs so often (a few cores per thousand machines) and is even increasing by pushing the hardware further to the physical limits, that its not a negligable problem.

One skill, I would really like to develop and improve in is listeing to people. How To Be A Good Listener gives great advice to that.
I’ve built this random page on top of Hugo with Markdown files that contain just lists, a list layout and some CSS. However, I could have also used shortcodes like I do for details. This might be a future improvement. Let’s see first where we’re going.
All continents on earth have female, latin names: Europa, Africa, America, Asia, Australia, Antarctica
The highest inflation ever recorded took place in Hungary in 1945/46 with a maximum monthly rate of 41.9 quadrillion percent. The stability of the Hungarian economy could only be achieved with the introduction of a new currency. Thus, on August 1, 1946, the forint was introduced, which was exchanged at 400 quadrillions (a 4 with 29 zeros; written out 400,000,000,000,000,000,000,000,000,000,000) pengő.

Setup git with multiple authors automatically

Wed, 28 Aug 2024 00:00:00 +0000

I’m pretty sure, I’m not the only one working in multiple git contexts with multiple authors. Maybe you also find yourself in situations where you need to juggle with multiple author configs, including:

Work
Private
Anonymous
and others…

I found myself multiple times already in situations where I’ve created a commit with my author set from work and vice versa. After countless errors, I finally found a way to manage this issue at my scale and I’m pretty happy with the solution.

SSH and GPG Relay inside WSL2 with systemd boot

Sun, 23 Jul 2023 00:00:00 +0000

In this post I will explain how I’m using the Windows OpenSSH and Gpg4Win agents inside WSL2 with systemd. This post is not explained in detail and serves mainly as a reference manual for future setups.

There are also other tools available in the wild, that help with the process, like:

wsl-gpg-systemd

Download npiperelay and wsl-ssh-pageant. Place both in a suitable directory on the windows side. I created C:\tools for that purpose. Configure wsl-ssh-pageant for autostart. I chose a simple shortcut in the startup directory for that. It should be started like this: wsl-ssh-pageant-amd64-gui.exe -force -systray -verbose -wsl C:\tools\wsl-ssh-pageant\wsl-ssh-agent.sock -winssh winssh-pageant

Do You Know the Power Intake of Your Computer?

Thu, 15 Jun 2023 00:00:00 +0000

I’ve measured the power draw of my computer and noticed that it only demands about 35W in idle and about 100W if doing CPU-heavy work

The @Transactional-Kotlin Mismatch

The JEE/Spring @Transactional Annotation in Kotlin behaves unintuitively when exceptions are thrown and does not rollback by default
