To keep track of various lists, such as books read, I use the CSV Touch iPhone app.

To publish the Calc documents on my website, I created this simple macro that shows a dialogue for userid and password before saving the spreadsheet as CSV file via FTP.

QCad 3.1 on Intel Mac OS X


Still using QCad to view and edit Autocad DXF files. Finally upgraded from the Qt3 version, QCad 2, to the 2012 QCad 3.1 beta which makes use of Qt4.

For an overview of all new features, see the QCad blog. New functionality I am happy with, though I do miss the old plain icons, in order of importance:

  • SVG export and import;
  • reverse line direction;
  • isometric projection.


Building QCad from the Github source is straightforward:

Calibre splash screen

As more and more e-books become available, it is time to set up an ebook library. The first open source alternative found, Calibre, turns out to be very useful and also does it connect to my (Kobo Glo) e-reader.

Urdu flashcards


Flashcards for the Urdu-Nasta’līq script, made from the Wikipedia alphabet chart. As common Urdu is quite the same as Hindi, it is a small step to learn to read it as well.

Best cut and paste the glyphs on strong (300+ gsm) paper cards yourself, no fancy digital stuff, so you can take your time, as needed for learning anyway.

A year after my introduction into music with the descant recorder, I now mastered the treble recorder well enough to play the accompaniment part of Henry Purcell’s Short Duets. The booklet contains brilliant pieces for the late beginner flute player.

Here is the electronic version (PDF 600KB) I created with Lilypond.

Der Mann ohne Eigenschaften

Der Mann ohne Eigenschaften

Eenvoudigweg omdat ie op mijn lijstje van te lezen boeken stond en nog onwetend van een onvoltooid werk begon ik aan Der Mann ohne Eigenschaften. Inmiddels gestopt bij de kleine lettertjes, de Studienblätter und Notizen, omdat dat in plaats van leesplezier teveel op een literaire studie ging lijken. Iets om later nog eens op te pakken.

Dit is mijn Schwere Wörter (PDF 88 KB) lijstje, voor wie het gebruiken wil.

Ziggo facturen download script

Ziggo factuur

Vooralsnog biedt Ziggo geen batchfunctie om al je facturen in één keer op te halen. Omdat ik die dingen zo ongeveer eens per halfjaar ophaal, hiervoor een web-scrape script gemaakt.
De Ziggo site, gebouwd met Backbase, leunt zwaar op JavaScript gegenereerde zaken. Daarom met gebruik van QtWebKit, PyQt4 en de Python webscraping library een scriptje gemaakt waarmee de gerenderde pagina’s ge’scraped’ kunnen worden.

De PDF facturen worden bewaard in dezelfde folder als het script.

Python script (en de webscraping library van 4 januari 2013) (700KB).
