About (Eng.) | The.Fischerman.CH

This blog is, first and foremost, my personal compendium of noteworthy security incidents from across the internet. I keep a tidy little workflow that lets me post articles I read straight to the blog — which means everything here is hand-picked and ever so slightly curated. The original pieces are always linked at the bottom of each post under “Source →” or “Quelle”. Older tweets should, in theory, still lead to Twitter (assuming Mr Musk hasn’t moved the furniture again).

The article explaining how the AI-generated posts are created “automatically” can be found here → “How Links Became a Machine”.

I am currently working in the product design at a well-known Swiss Security Provider.

(And no, that’s not actually me in the image above — it’s my virtual “Fischerman.ch” persona for this blog. The image was generated with AI.)

You’ll also find a few of my hobbies dotted about the blog: music, tech gadgets, “tech tinkering”, and various IT projects such as the ISMS work, or playing with AI in JavaScript, Perl and other languages. I am most definitely not a developer — I happily let AI lend a hand there.
