Business models: Bookboon and iText

A while ago, I read an announcement about BookBoon. It was about quality ebooks on a plethora of different subjects, and as it's our mission to enable a paperless world, pushing the limits of digital document interactivity, I visited the site and I discovered that Bookboon allows you to download quality content in the form of PDF documents.

Moreover these books were offered for free and it's totally legal to download them. How is that possible? How do these guys make money? What is their business model? Is there a business model? Of course, there is! But first let's take a look at the site:

We're already looking forward to some more articles!


A very long time, I made a Facebook page for iText, but as I wasn't a Facebook user myself, I neglected that page. Recently, I updated my own account:

A Google+ API written in Java

Michael, one of our iText developers, is currently working on a project that involves interfacing with different social media services to create PDFs using data (posts, photos, movies,...) aggregated from different online sources (your Twitter account, your Flickr account, your Youtube channel,...). Often there are APIs available, although the documentation isn't always as good as it should be. Sometimes there's an API that doesn't work as expected. For instance: the API for Google+.

Praktijkboek Informaticarecht

This blogpost is in Dutch because it's about a book written in Dutch.

Vorige week ontving ik het 'Het Praktijkboek Informaticarecht: Recht rendeert voor uw onderneming' van Ywein Van den Brande (Crealaw):

Ik was eigenlijk van plan wat programmeerwerk te doen dit weekend, maar ik dacht gisterennamiddag: laat ik toch maar eens het eerste hoofdstuk beginnen. En raar maar waar: ik heb de 198 pagina's in één ruk uitgelezen.

Silicon Valley January 9 - 20

Many of you have been following the photo blogs about our visit to Silicon Valley. Today, I found out that my smartphone has registered different locations on Google Latitude. It's a pity the time registrations reflect the Belgian timezone instead of the local time in California, but still: you get a good idea of the miles we've travelled.
The first day (in local time partly Sunday, partly Monday), we didn't travel much:

The second, third, fourth, and fifth day, we went to the Plug & Play Tech Center on a daily basis.

Coming up next: introduciong iText on Heroku!
