Book party April 29

The "iText in Action" book party was a success. We didn't take much pictures, but it was fun to bring the old and the new colleagues together, and have them meet with some of our business partners. This is a more personal photo:

From left to right: my father, my wife, our two sons, myself, and my mother.

I don't know what we were talking about in the above picture. I think I was making some kind of silly joke (as usual).

Google Analytics — April 2011

Another month, another Google Analytics blogpost. Let's take a look at the Google heartbeat:

Do you notice the difference with the normal heartbeat? Look at the days before and after Eastern. There's a small disturbance there. It's more subtle than during the Christmas holidays, but it's there for sure: people don't visit the iText site when they are on vacation ;-)

Books I've read last month

My last blog post about books dates from March 27. I continued reading The Chronicles of Narnia, but reading the seven books in a row feels like overkill, so I took a break after part 4 and 5 (or part 2 and 3 if you look at the publication order, rather than the logical reading order):

C.S. Lewis, Prince Caspian; 1951, p471-642 (from The Chronicles of Narnia; translated as Prins Caspian)

"iText in Action" excerpt on Javabeat

When my first book was published, I enjoyed searching for "iText in Action" and I blogged about every site where it was mentioned. Now that there's a second edition, I no longer have time to do so.

The iText Office: after week 4

Last week, we had somebody come over for the electricity and for the floor:

This weeks will be a slow week. Normally, they'll continue working on the electricity (new fusebox, network plugs, etc...), but we have to wait 6 weeks for the lighting and we didn't contact somebody to paint the walls yet (they aren't dry enough to start painting anyway). We also didn't decide on the new office furniture yet.

The iText Office: after week 3

Today, the room looks like this:

Next week: electricity (wires, outlets, fusebox,...) and a new floor.

The impact of Twitter, LinkedIn, FB on two blog posts

In my previous post, I showed the graph of the visits to in general. I wrote that you one specific blogpost was responsible for a huge peak on March 31. This inspired me to look at the stats of the two most important pages of March. The first one is the Invoice demo page.

Every month, I post the results of the site on Google Analytics, and I add the results of as an extra. This time, I'll do it the other way around. You'll immediately notice why:

On March 31, the number of hits doubled from about 250 to about 500. Why? Because of a single blog post in Dutch: Ondernemer tegen wil en dank that was plugged on different places.
