This is a repost of a note I originally published on my Facebook account on August 12th, 2016, in German language. Vielen Dank, dass du meinen Artikel geöffnet hast. Es würde mir viel bedeuten, wenn du ihn zu Ende lesen würdest und mir Rückmeldung gibst. Es geht um Chatbots, Conversational Commerce, die Facebook Messenger Platform und ein Produkt, das ich entwickelt habe.
When I heard about Flappy Bird for the first time, the hype was already in its final phase: developer Dong Nguyen had decided to pull the app from the stores in “22 hours from now“. Apart from overreacting users and an allegedly daily advertising revenue of up to 50,000 US$, the simple game mechanics were something that caught my attention. The concept of clicking/tapping to keep the player on track wasn’t really an innovation in itself, but given the hype it caused, it was certainly worth a closer look. As a Sunday evening challenge, I tried to reproduce the game mechanics and ended up with less than 200 lines of code. Update Feb. 20th: I added the score counting part and included suggestions by readers Sascha and Nico. Updated code is pushed to GitHub. Update Feb. 27th: Fixed a small glitch in the tutorial that DylanYasen pointed out, thanks! (No code change.) Update Apr. 9th: Sorry, I currently don’t have time to update the tutorial. In the meantime, take a look what reader Daniel Bocksteger …
Around the same time in 2011, I wrote a posting about the LeWeb 2010 finalists and startup success in general. I placed a reminder into my calendar to revisit the list in 2012 and went to check whether the companies were still alive and well. Unfortunately, I never released the post. Now, another year later, I saw the unreleased draft and decided to update it once again.

Earlier last week, I installed Nginx with a Tomcat on my Ubuntu VPS. I decided to give the “APR based Apache Tomcat Native library” a try. Here’s what I did.
Mind your brackets when defining GORM parameters.
At dozens of different sources it says that you need to put grails.tomcat.nio=true into your Config.groovy file – apparently that’s not true, at least it wasn’t working for me.
I got this exception while working with MongoDB and the MongoDB Java driver I got this exception, caused by a simple type mismatch.
This posting describes the steps necessary to change your Grails project if you’re using Grails for frontend only, without direct database access.
I was interested in whether there’s any truth in this startup-scene meme, so I took some time to walk through 13 startups who presented 30 second pitches at Web 2.0 summit 2010, a little more than one year ago.
While porting my Grails applications to 2.0 RC1, I recognized that ConfigurationHolder is now deprecated. The new way to access the configuration is through dependency injection of the grailsApplication bean. Before 2.0: With 2.0:
