Rails Decorators using the Draper gem


You might have experienced this yourself: Over time, Rails models are getting fatter and fatter and the complexity of helper classes increases.

The 1st Babbel Hackday


Friday, April 4th, we held the first Babbel Hackday. Starting at 10 a.m, more than 40 developers, designers, analysts and product managers gathered at Co-Up at the backyard of the Adalbertstraße in Berlin-Kreuzberg for a full day of hacking madness.

The complete staff of Babbel’s Product and Engineering departments and the BI team took part in the event. At Babbel Product, Engineering, and BI work closely together on various apps for web and mobile platforms. While our main goal for the Hackday was to bring people together through temporary teams for light-hearted, hackday-only projects, we also intended to provide some space for any ideas lying dormant in the existing teams. We also just wanted to have a fun day, and we were anticipating some great results.

Developing the Babbel Android App


Babbel’s mobile apps continue to be a huge success. After we shipped our new iOS7 apps, it was time to give the Babbel Android App a treat and turn it into a full-feature app. Babbel is striving to provide the same user experience across all devices. No user should ever be hindered in her/his learning activities by having to adapt to different user experiences on Android, iOS or the web.
