  1. Travel in New Zealand

    To get from Auckland to Napier I had booked a domestic flight because that should take only one hour instead of eight by bus!

    Do make sure that there is sufficient time between the arrival of your international flight and the boarding of the domestic flight. We ware slated to ...

  2. Travel to New Zealand

    On the 18th of December I left for NZ. Compared to my previous journeys I did not do a stopover but just switched planes. This time in Seoul. This switch took quite some time; the arrival and departure gates were far apart, even taking into account that you had to ...

  3. vid2mkv

    My digital camera can also produce movies, like most camera's these days. It saves them in AVI format, with relatively poor mjpeg compression and uncompressed sound.

    So I wrote this python script to convert these AVI files to Theora / Vorbis streams in a matroška container. It takes the video ...

  4. vid2mp4

    Videos with H.264 video and AAC sound im MP4 containers seem to strike a very good size performance balance. So I modified a copy of vid2mkv to use ffmpeg to create this kind of files instead.

    To speed up the processing of multiple files, this script runs the conversions ...

    This shell-script makes a backup (with the tar program) of the directory from which it is called, with all its contents. It is one of the smallest scripts I've ever written but I've found it really useful to make fast complete backups of e.g. source archives.

    The ...

  7. Switching to the vim editor

    After having been an emacs user for a long time, I was starting to grow disenchanted with it around version 24. My main problem is that it was starting to get really slow. Not just in starting up, but also in daily use, specially it you kept an instance open ...

  8. Chickpea and vegetables stew

    This is a variation on a recipe that I found in a cookbook, because some of the ingredients in that cookbook aren't in season right now.

    The ingredients I used were:

    • one can of chickpeas (400 g)
    • one can of diced tomatoes (400 g)
    • 250 grams of French beans ...
  9. Making my first EPUB

    Now that I got an EPUB reader, I started looking for a way to make EPUB documents.

    In principle, an EPUB file is a zipfile with a certain layout, as can be seen on the wikipedia page linked above.

    The actual contents are just XHTML, while the metadata files are ...
