An Open Door to Open Source: Relive our OSS Conference

At the end of last year, to celebrate our continued sponsorship of the Open Source community, we hosted a small conference with special guests at our Düsseldorf campus. We initially hoped to welcome Tobias Koppers and Sean Larkin from Webpack, plus some internal speakers. What we didn't expect was the huge amount of fantastic speakers who wanted to present their projects to the community. In the end, Sean unfortunately couldn't make it but we did have a chance to welcome Marvin Hagemeister, Juan Picado, Norbert de Langen and Pia Mancini as speakers, plus our own amazing talents.

Better URL Search with Elasticsearch

At trivago, we generate a huge amount of logs and we have our own custom setup for shipping logs using mostly Protocol Buffers. Eventually we end up with some fields in Elasticsearch (ES) that contain partial (or full) URLs.

At trivago we live diversity. We have 55 localised platforms and internally you can find talents from around 90 different nationalities all working towards providing a better experience to our customers. We are constantly evolving as we face organisational, societal and industrial challenges.

We strongly believe in sharing knowledge not only internally, but also with the tech community around the world.

Getting Ready For The Big Data Apocalypse

trivago Intelligence was born in 2013 with two main objectives: First, to provide bidding capability to the advertisers, who are listed on trivago, and second, to provide them with metrics related to their own hotels; like clicks, revenue, and bookings (typical BI data). This project faced a wave of inevitable data growth which lead to a refactoring process which produced a lot of learnings for the team.

How to Analyze SurveyMonkey Data in Python

As a user researcher, it is important to know more about our users and their preferences concerning our product. One way to do that is by conducting surveys.

In order to gather user feedback from our global markets, we need to conduct a survey with a slightly different set of questions/translations for different countries, and then analyze the results and compare if there is any difference across countries concerning user needs.

Circuit Breaker with AWS Step Functions

At trivago, we have several workflows which interact with external services. The health and availability of external services can have an impact on keeping our workflows alive and responsive. Think of an API call made to an external service which is down. Our workflows have to be prepared to expect these errors and adapt to it.
