Signing a PDF with a smart card

Writing about technical topics is fun because it's a job that allows you to try out a variety of things before you actually start writing about it. This morning, the first 30 pages of my white paper about digital signatures were sent to all the subscribers of our news letter. I'm very curious about the feedback I'll get.

Early Access Preview: Digital Signatures in PDF

After writing my second book in 2010, I thought it would take me another 3 years before my taste for writing would return, but no: I'm very eager to write new material, and I'm grumpy if other work gets in the way.

Google Analytics — May 2012

Times flies. I've hardly had any time to blog last month. I'm even late with my monthly analytics report:

The heartbeat of iText in May shows some arrhythmia caused by public holidays in different countries: the first of May in Europe, the Ascension and Pentecost in the Christian countries, Memorial day in the US,... It's amazing that these dates can be visualized in the analytics reports of the site of a technical product.

How I started using Pinterest because I loved it...

... and why I continue loving Pinterest because I use it.

When I first heard about Pinterest, I thought: What is this about? Let's request an invite.

I thought it was something in-between FlickR and Facebook. I didn't see any use for it, but I loved the interface and its simplicity, so... why not give it a try?

Google Analytics — April 2012

As predicted, the statistics for April aren't as good as usual because of the Spring break and the Easter holidays:

These vacation periods may not be visible in the heartbeat of the 'visits', you can clearly see it in the graph of the Alexa ranking:

Book sales update

We found a huge pile of mail after returning home, and now I'm going through all the letters, invoices and other mail we received in the last few weeks. One of the letters I received contained the book sales for 11Q4. For some reason, people are still buying the first edition. In the world of IT books, you have a bestseller as soon as you can sell 5,000 copies. And yes: the second book is now at 5,394 copies. That makes it official: I've written a second bestseller!

Google Analytics — March 2012

We had a successful summit a week ago, I taught an iText course in Paris this week, and now I'm preparing for a business trip to the US next week. This means I have plenty of work, and very little time to blog. I didn't even have time to look at the Google Analytics results for March until today:

Did we break any records?

iText 5.2.1 — XML Worker 1.1.3

I'm preparing to teach an iText class in Paris, and to give some demo's in Oakland. I'm currently making a new set of examples for some new chapters I'm going to write (maybe a third book, not a revision of the second edition, but a book with some advanced topics). Whilst making examples to explain the different options available in XML Worker, I found some bugs and I also thought about some functionality that was missing.
