A recap of yesterday’s Berlin Ruby User Group meetup

We like developer meetups. That’s probably the reason why we found ourselves at the Berlin Ruby User Group (short: RUG::B) meetup at the Crealytics office yesterday. Just to recap the three talks and lightning talks real quick:

RabbitMQ to the rescue

First up was ‘Ruby Storm – Distributed work on a self-scaling system using RabbitMQ‘, where Steve Creedon and two of his co-workers at Wimdu walked us through their complicated integration processes of daily (data) feeds from partners for properties, availability and prices. Wimdu currently manages 360 000 properties with information on their availability and price, from 1700 partners. Creedon: “The first feed contained of 670MB XML, 30.000 prop, a steady daily feed for 1 partner. It took 27 for 1 script.” (more…)

We sponsored Kod.io Linz – here’s what happened

Kod.io Linz took place last weekend at the Ars Electronica Center in Linz. Being one of the incredibly proud co-organizers of this developer conference, my recap might come across a little biased, but I tried to keep the amazing‘s to an absolute minimum. We’ve collected all slides and pictures, and can’t wait for Confreaks to publish the talks.

CSS secrets and platform-native app development

The conference day started with 2 keynotes in our separate tracks. In the Seminarraum Lea Verou explained in ‘The Chroma Zone – Engineering Color on the Web’ how color works on the screen. How? Well… White pixels make up of 3 RGB subpixels, which can have a different order and different subpixel intensities for different colors. She elaborated on the workings of RGB, HSL and relative luminance. Hinting what CSS4 will bring us, Lea mentioned the new gray value(xx%) – unsupported now, but can be poly-filled with sass – and new adjustors: tint, shade, blend.

Steve Scott talked about the benefits of platform-native application development and explained why RemObjects have made the choices they have in producing their cross platform native tools. He also took the opportunity to announce the release of RemObjects C# – a brand new tool for native C# development on mobile platforms. (more…)
