My random knot in the Web

  1. Commuting on a zero DSR

    At the end of 2020 I purchased a Zero DSR to use as my main transport for commuting. These are my experiences after approximately the first year.

  2. Decoding temperature data logger files

    At work, we recently bought an EBI 40 TC-01 6-channel temperature logger. It saves data in a file with the ed3 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.

  3. 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.

  4. 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.

  5. Switching to SSH keys for github

    This article covers some aspects of using SSH keys with github that are left out of the original documentation on github.

    It assumes that you’ve been using HTTPS with a password for remote access to github.

  6. Making ringtones with open source tools

    Most smartphones come with a range of ringtones.

    But if you don’t like those, you can make them yourself from music that you are allowed to use.

    All software that is used here is open source. They should work on all recent UNIX-like operating systems. In my case, I installed all of these programs using the FreeBSD ports system.
