Switching to Lektor

Sat, 26 Aug 2023 by Uwe Kamper | Categories: personal-projectweb-development

This website used to be generated by Hyde, a Python-based static site generator. Hyde has since been abandoned (it still works with Python2 only) and anyway there are more advanced static site generators available today. So I decided to redo this website using Lektor.

Make your hackerspace/conference network suck a little less with traffic shaping

Tue, 09 Apr 2013 by Uwe Kamper | Categories: networking

The problem is: Most cheap internet connections have asymmetric upload speeds. For example, one conference I attended had a cable line with 100 Mbit/s downstream bandwidth – but only 5 Mbit/s of upstream. As soon as someone starts using the network to upload data to the outside internet, the whole upstream channel is blocked.
