Installing Openstreetmap data on a Garmin zūmo 340LM
This documents how you can install openstreetmap data on the Garmin zūmo 340 LM. This procedure probably also works on other Garmin devices, but I haven’t tested that. The commands listed in this article assumes you’re using a UNIX-like operating system. While most of the actions could be performed on ms-windows, I haven’t run that in decades, so I’m not the person to give advice about that
Commuting on a zero DSR

extension. It comes with a ms-windows program to show the data and export to CSV and ms-excel.However, I want to be able to use the data on my FreeBSD workstation. So I have to figure out the data format of the
ed3
files.Building an epub from a single ReStructuredText file
The sphinx documentation generator is a an excellent tool. It was written to generate documentation for Python, but is used by many other projects as well. Its source format is ReStructuredText.
These webpages are written in ReStructuredText as well, and I also use this format for other bits and pieces. On occasion, I want to convert a single ReStructuredText file to an epub. This article documents how to do that.
Continuum properties of aluminium honeycomb
Honeycomb cores are often used in composite structures as an alternative core material to e.g. polymeric foams or end-grain balsa.
In FEA we want to be able to treat honeycomb as a continuous material instead of having to model individual cells. Otherwise even simple FEA models involving honeycomb would become unmanageably large.
