About

This is the personal blog of Jonas Juselius. I started programming at the age of 8 on my mothers Olivetti PC, and received my Ph.D. in quantum chemistry in 2004. For the past 10 years I have been working in High-Performance Computing and software development. In 2012 I discovered functional programming and Haskell. Since 2015 I have been leading the development group at Serit Tromsø AS, working full time with functional programming mostly in F#. I also hold a position at UiT The Arctic University of Norway, where I teach functional programming at the Department of Informatics.

For a long time I used to have a nagging feeling that there was something fundamentally wrong with programming. Programming was reminiscent of mathematics, but without the kind of rigor one would expect. All rules could be bent and broken at will. When I discovered functional programming back in 2012, it had a profound effect on me. All the pieces fell into place, and suddenly large parts of programming got reconciled with mathematics. This has an immense effect on code quality, complexity and number of bugs. Functional programming has long since come of age, and is not an academic exercise.
