d’Schwiiz inerem Schiffli: Pfäffikersee

So it hasn’t been all work: the weather (though it’s tragic today) has cooperated with my calendar on occasion, and I’ve had a few chances to throw the boat on the water. So this begins what I home will become an occasional series on paddling around Switzerland with a sea kayak.

The weekend before last, I decided to try out the Pfäffikersee (“Lake Pfäffikon”, though the lake isn’t really big enough to warrant a translation). At 2500m x 1200m, it’s possible to do a full roundtrip around the lake in about an hour without pushing too hard.

A quick introduction to IPFIX

I recently gave a full-day course on flow measurement at the University of Zürich’s IfI summer school. The course itself was more or less a stack of my current research interests stapled together; one product was a nice summary version of a tutorial on the IPFIX protocol (on which I’ve worked on and off for the past nine years), together with an iPython notebook on the subject.

Slides are here, and the notebook is here. The live version is available from GitHub in the britram/ipfix_tutorial repository.

And as a bonus on the subject, here’s a video of me giving an interview about all this last year in Berlin on way too little sleep.

Well, it’s official. I’ll be joining the Internet Architecture Board for a two-year term starting at IETF 89 in March. Among other things, the IAB provides architectural oversight of IETF protocols, which are surprisingly coherent given the nearly perfectly bottom-up nature of the process that produces them. I look forward to the challenge in meta-cat-herding.
