Why / What is this?

This is because I needed an easy to access place to document solutions and store snippets/hacks for myself and people around me. Before, I mostly used gists1, other pastebins, and a bunch of repositories2 but it was a pain to search for stuff and provide documentation.

Nevertheless, this is still a very chaotic place where I dump arbitrary content I find useful. Some might also be useful to you; most won’t.

However, if you find serious flaws or have some valuable input for me, please feel free to contact me.

Who am I?

I am a cs researcher and software engineer, currently working at EclipseSource since 2022.

Previously, I worked (full-time) at

  • WU Vienna (Institute of Information Systems & New Media) from 2019 - 2022
  • University of Passau (Chair of Software Engineering) from 2012 - 2018

Please see my GitHub profile for a more complete overview of my publicly available work.

If you’re interested in contacting me about work projects or academic/research related topics, please use this work e-mail address that is consistent across employers: olaf.lessenich.work@gmail.com.

As my professional workflow is entirely based on open-source software, I also enjoy contributing bugfixes or features to projects I use or follow.
See also software I use.

In my free time I enjoy exploring my current city (now: Vienna) and its surrounding nature, books, chess (on a very sad amateur level), and most recently photography (also on a very amateur level).
