My name is Toke Høiland-Jørgensen. I’m a Linux kernel developer at Red Hat, where I work on the upstream kernel networking stack with a focus on XDP. I completed my PhD in November 2018 at Karlstad University in Sweden.
I have been involved in the bufferbloat project for several years, and apart from my kernel work, I am also the author of the Flent performance measurement tool and the sqm-scripts QoS configuration tool for OpenWrt. I also occasionally write other code, most of which I collect on Github.
When I’m not sitting in front of a computer, I like reading books, playing music (I’m a fairly mediocre drummer), and going rock climbing. And lots of other stuff that is too unspecific or boring to mention here.
Reverse chronological order. Sadly didn’t do this from the beginning, so am in the process of reconstructing the list after the fact. For now, it goes back to December 2017.
