I mainly post on the [PyPy blog](https://pypy.org/blog), but there are sometimes things I write that don't really fit there. In 2018 and 2020 I wrote [two](/sinus-fischer/) [essays](/city-abstracts/) about (computational) art which lived on glitch.com. Now that that is going to shut down, I decided to migrate and backdate them here, together with some shorter backdated draft posts that never really made it anywhere (or only to social media).
