Since I am a employee of trivago I have the privileges of working at our Mallorca office. We own a house on the island as big as a mansion. I am sharing this house at the moment with 6 colleagues. There is room for 12 persons. Here are some pics:



The house is beautiful, the island is beautiful, the people are beautiful but in the end I am here to work.

For a campaign in March 2015 trivago bought some banner space at The campaign will only be live for one day and here is the flash banner that will be shown.

I have created the banner in Flash CS6 with as3.

It is not one banner but there are actually two banners

1. format 180×850, max. size 40 kb
2. format 321×250, max. size 50 kb

There are 46 links inside the two banners.

We expect that on the day that we start the campaign. There will be around 8 million visitors on

While setting up the test server at trivago, my new playground ;). I found out that there was a bug inside the HTML5 moon dealform creatives. The dates inside those creatives are updating, depending of the current date of the user. While debugging I also took a closer look into bootstrap here is the result. I have to investigate this it seems legit for the job.

I was checking my twitter when grapefrukt tweeted that he is doing live game development. I really enjoy watching him coding/designing and chatting about what he is doing. Here is the twitch page : I am not sure if he is live now ;)

The tools he is using are : Haxe, as a code editor he is using flashdevelop and I see him using Adobe illustrator. I think these twitch live webcam/ coding streams are very inspiring and entertaining.
