Hello, world ! Welcome to the weblog of Kristof Willen. This is the place where I publish some weird and interesting links I encountered during my dwellings in cyberspace. Apart from that, you can find some useful/useless information about myself.

After reading a post about making your own Albert Heyn bonus cards, I search a bit around, and quickly discovered barcode (duh), a Unix command line program, which makes barcodes of an excellent quality (in PostScript).
Most barcodes on items here in Europe, are in EAN-13 code, which you find explained here. The first 2 or 3 characters are used for country codes. For example, Belgian manufactured goods are labelled with a barcode beginning with 54.
