Flying on a paraglider lets you go places with some unique perspectives - sometimes not even accessible to airplanes.

After I released the first version of SkySee - see skysee.ch - I quickly received feedback, and also felt myself, the limits of a pure SHV number based tagging.

Context In the past weeks, I’ve built a web application from the ground up, scratching an itch I’ve had for a long time.

How time passes!

In my job at Zurich Instruments, I’m busy most days building software for a quantum control system (QCS).

New article, discussing recent developments and improvements: News in uvco I’ve already presented my “uvco” library in a previous post.

I’ve programmed in C and C++, later in Rust and OCaml, for more than 12 years now.

While working on some programming quiz in OCaml, I needed to use a priority queue (or heap) in order to solve some graph traversal problem.

Updated: May 7, 2024 New article, going in depth on uvco: Design of the uvco async library Since starting my new position at Zurich Instruments I’ve worked a lot with the lovely kj framework, in conjunction with capnproto RPC. kj is an asynchronous network

While working on typst_of_jupyter, I came across a very common problem: efficiently and reliably accessing nested JSON structures.

If you have followed my posts (unlikely, given the visitor counts of my website), you have seen one or two posts about Typst, the new text-based typesetting system.

A few weeks ago I finally started seriously working with OCaml, after having ignored it for a long time.

The “secret” to the most cliché idyllic landscapes is to not look in the alpine regions, but in the foothills preceding them.

Background Over the past years, I’ve repeatedly seen articles claiming a looming shortage of lawyers: Reuters: “Could the legal industry be entering a long-term lawyer labor shortage?”

In my second post on Typst – after the CV template which already ranks me fairly high in the search results for those terms :-) – I want to present a use case of Typst I found while working on my master’s thesis on integrated photonics devices for multipl…

Updated 2023-08-30 If you are interested in typesetting outside the normal options (Word, LibreOffice), and have had a gnawing feeling that LaTeX is, after all, a bit annoying to use (and I say that as a maybe not power user, but having used it for the pa…

I’ve recently had the privilege of meeting several lovely cats who agreed to have their photos taken (at least that’s how I interpreted their behavior).

Disclaimer: I have little knowledge about the details of quantum computing!

Could you imagine an internet with just text?

After noticing that by far most visitors to my website don’t come for my technical/scientific content (sad!)

I walked off the busy Hollywood streets – with the LA pride in full swing – into the Hollywood hills.

Every student in quantitative sciences – I will argue – sooner or later comes across the weighted mean, a tool to incorporate measurements with different uncertainties into a overall measurement of better uncertainty than any single measurement.

Staying in California obviously gives some great opportunities to take amazing photos.

Minor works or interesting tidbits go here.

In the past half year, I’ve implemented various data analytics algorithms for my own understanding.

A very important concept in condensed matter physics (or solid-state physics, specifically) are lattice vibrations and their quantized form, phonons.

updated: 2021-12-27 Towards the end of my Bachelor’s program, I decided to broaden my horizon and expand my options – and subsequently enrolled not only for Master’s studies in Physics, but also in Economics.

I like taking photos of my university campus; so much, in fact, that I’ve created a Flickr group dedicated to it.

I spent this past summer writing my Bachelor of Science thesis at RWTH Aachen’s Nuclear Verification and Disarmament chair (Prof.

This article about why nuclear energy is questionable in this day and age is written in German, as the topic of leaving nuclear energy is actively discussed in these days in Germany.

Unfortunately not always, but sometimes, I have a mind free enough to just go out and take photos.

updated 2021-07-14 “Bayesian Inference” – sounds fancy, eh?

Just recently I bought an Auto Revuenon 55mm (f/1.4) lens off of ebay.

There is this meme floating around (you can google for it, and find many instances), that machine learning is just statistics (and sometimes even just a linear regression).

Geohub on Github A couple months ago I finally realized an idea that I’d had for several years.

One of my favorite kind of scenes is nightly cities.

The RWTH’s general student’s committee (AStA) put out a call for Zoom (video conference) background images, in order to “spice up” the online studies.

Inspired by drudging through optics material for a recent exam, I wanted to get a more intuitive feeling for diffraction phenomena, specifically diffraction of spherical waves through a plane aperture.

As part of a seminar I recently took with Prof.

Aachen is – at least among locals – known for its brilliant sunsets and dramatic weather.

Please contact me and I will gladly send you my CV in either English or German language!
