You can find the pbsf-lib Python module on GitHub; follow the installation instructions in the README.md.

bpost has a postal code validation tool, providing a spreadsheet of postal codes with names of Belgian communes and their deelgemeenten.

Social media platforms provide value to independent creatives by allowing them to fully focus on creating instead of having to figure out how to share their work.

Sequences Linear Order In a sequence, each element directly follows at most one element and precedes at most one other, forming a linear chain.

See 2024; will post "> 1000 kilometres in 2026" next year.

Letterboxd allows users to list up to four favourite films, but there’s no built-in way to find people with similar tastes.

This is an abbreviated transcript of my FARI “Happy Hour” talk titled “Using AI to Detect the Unusual”, held at BeCentral on the 25th of November, 2024.

In this write-up, I go over the step-by-step solution of “Hell’s Hex Station”, a challenge I created for the 2024 edition of Infogroep’s Capture the Flag.

I believe large language models can bring value in use cases where they assist with tasks like summarising, translating, and reformulating text.

I recently wrote an Espanso trigger named :llm(⋯) that pipes the contents of my clipboard to Simon Willison’s llm CLI tool and expands the trigger to llm’s output in a custom Obsidian callout.

In August, after learning about the IndieWeb, I updated my website and turned it into this blog.

During the programming and writing of “Automating Boggle”, I remember being surprised that popular AI models (like GPT-4) — capable of many remarkable tasks — couldn’t do something so “trivial” as reading rotated dice.

I work on my Git repositories from different machines, which separates my contributions over different Git identities.

After years of lurking on Twitter — barely contributing to conversations on the platform, and only using it to read tweets from creators I follow — I am trying out Mastodon for a while.

As I also plan to upload non-technical posts and notes on my website, I added the ability to filter content based on categories.

Thanks to a blog post by Simon Willison, I learned about the open-source Python tooling by Astral.

A couple of days ago, I made a simple addition to my Pomodoro timer.

I started experimenting with the Rust programming language by reading “the book”, trying some basic things and loosely following along with the examples.

When exploring Overture data earlier this month, I stumbled upon “All Streets” by Ben Fry.

As I plan to write about a variety of different topics on this website, I decided to add tags to the properties of all my posts and notes so far: --- title: "Displaying tags in Hugo" date: "2024-08-19" tags: ["hugo"] ⋯ --- Tags were already available in…

Until now, I have been storing different variables as site parameters in my Hugo website’s hugo.toml file.

TETR.IO’s started its new season yesterday.

Today, I participated in my first duathlon — 5 kilometres of running, followed by 32 kilometres of cycling, and finishing with another 5 kilometres of running: Run #1 00:24:54 ⋮ Transition #1 00:01:06 Bike 01:21:49 ⋮ Transition #2 00:01:53 Run #2 00:23:44…

For both training and racing, I use a Stryd pod: a running power meter that allows me to base my running on my power output, instead of looking at my pace or heart rate (which are both influenced by elevation).

I usually use the Pomodoro Technique to schedule my work: intervals of 25 minutes of work, followed by a 5 minute break.

Since 2022, I’ve regularly enjoyed playing a competitive Tetris variant named TETR.IO.

A partially ordered set — or poset — $P = (A, \preceq)$ is a pair consisting of a set $A$ and a partial order $\preceq$ on $A$.

Yesterday, I learned about sparklines — “data-dense graphics with typographic resolution that is shown inline and in-context with relevant text.”

I recently learned about Overture places data through a blog post by Drew Breunig.

Intervals.icu API I sync all my Strava activities to intervals.icu, which calculates my training load, fitness score, and my weekly ramp rate.

I added custom tooltipsJust like this one!

For my work, I picked up the habit of transferring my daily notes and insights from my physical notebooks to an Obsidian vault.

I am using GitHub Actions to automatically create new daily notes on this website.

I switched from Notion to Obsidian.md to keep track of meeting notes, to store highlights from scientific papers (using a Zotero plugin), and to maintain a knowledge base for my PhD research.

Last week, I had a conversation with a good friend in the spirit of the “Cult of Done” (valuing action over perfection, boldly experimenting and learning through doing) and sharing our work.

In this short write-up, we will go over two challenges in the Misc category of Inferno CTF, which was hosted by Dc1ph3R.
