Svante von Erichsen ( will be presenting:
"How I learned to stop worrying and ignore anomalies"

Anomalies are a way to return errors in your program flow, made
popular by e. g. several Cognitect libraries. We recently published a
toolbox, de.otto/nom ( for ignoring
them on the happy path. In this talk, we'll see what it does and
compare that with some alternatives, such as railway-oriented
programming, exceptions, and Failjure. This might be a missing piece,
a sweet spot, or a crazy idea.

Svante is a software developer at OTTO, a large e-commerce platform
from Hamburg. Originally a chemist, he started learning Common Lisp
around 2008. After starting with professional software development in
2011, he joined a startup using Clojure in 2016, and in 2018 switched
to a team at OTTO also working in Clojure. His non-programming
interests include playing Go, training Karate, and making Music.
