R User Group: Method Comparison Studies (MCS) by Kevin O’Brien at Hypoport (17.12.2015)

Doors open at 19:00
After short introductions and “Open Mic Session” the main event starts at 19:30.

Kevin O’Brien (University of Limerick, Ireland) talks about Method Comparison Studies with R : A whistlestop tour of methods and techniques for one of the most commonly encountered problems in sciences.

Kevin O’Brien is a teaching fellow and PhD candidate in the University of Limerick, Ireland. His research interests pertain to statistical methods for medical and clinical applications. He is involved in several tech communities, for example as the organizer of the Dublin R Users Group, an R mentor at Coding Grace Female Friendly Workshops and as PyData co-ordinator for Python Ireland. Kevin is going to talk about method comparison studies (MCS) with R.

GOTO Night: Data Modeling for Elasticsearch at Hypoport Oct. 22

Hypoport invites you to an interesting GOTO Night with Florian Hopf on behalf of GOTO Berlin.

The session will start at 7PM on October 22, 2015 at Hypoport headquarter Klosterstr. 71, 10179 Berlin. Please come by and give us a visit. Food and Drinks will complement the session.


One of the factors for the huge success of Elasticsearch is that it is really easy to get started with. Format your data in JSON, push it to Elasticsearch and instantly you have a full blown search server available. But sometimes it is not that easy and you have to tell Elasticsearch how to manage the data.

In this talk we will explore how Elasticsearch stores its data and learn about the basic principles of index based search. We will look at some of the algorithms and data structures that are responsible for making Elasticsearch as blazingly fast as it is and see examples of how we can benefit from them in our projects.


Florian works as a freelance software developer in Karlsruhe and likes to work on search systems built on Lucene, Solr and Elasticsearch. He helps to organize the local Java User Group as well as the Search Meetup in Karlsruhe and he blogs at http://blog.florian-hopf.de.

JavaScript Forensics by Todd Gardner at Hypoport (Sep. 24th !!!)

Todd Gardner of TrackJS will be at Hypoport THIS Thursday Sep. 24th.

Something terrible happened here. Traces of errors litter the floor; memory leaking from cracks in the ceiling. Someone lost their object context in the corner. Everything reeks of jank. In this session, a JavaScript error tracking expert breaks down a series of common and complex crimes against web applications. You’ll leave the session armed with techniques and tools to detect, diagnose, and fix your JavaScript web applications. Bring your bugs and let’s fix up our web.


Get together at 6pm
Talk starts at 6:30pm

Before, meanwhile and after the talk you can grep a drink and some food.

It would be great if you register here.

Kind regards, Leif

“Entscheidungsfindung in der Gruppe” erntet große Resonanz bei der IS24 Pecha Kucha Night

Kennst du das auch? Wenn es darum geht, gute Entscheidungen in der Gruppe zu treffen wird es manchmal ziemlich kompliziert. Während einige Kollegen Feuer und Flamme für den Vorschlag sind, sehen andere schon Risiken oder Verbesserungspotential und schon wird lustig debattiert, anstatt effizient zu entscheiden. Wir haben das in diversen Situationen erlebt. Versteht mich nicht falsch: natürlich sollen alle diese Rückmeldungen aus der Gruppe berücksichtigt werden. Die Frage ist vielmehr, wie wir Gruppenentscheide systematisch verbessern können um gemeinsam effiziente Entscheidungen zu treffen.

Einige spannende Ansätze fanden wir bei der Holokratie, genauer gesagt mit dem darin enthaltenen Itegrative Decision Model (IDM). Wir haben diesen Prozess in verschiedenen Meetings ausprobiert. Das hat bei uns einiges an Erkenntnis gebracht. Zusammenfassend lässt sich feststellen, das wir bei Entscheidungsfindungen nun viel stärker auf Folgendes achten:

  • Sei dir klar darüber, ob es jetzt darum geht eine Idee besprechen bzw. entwickeln oder einen konkreten Vorschlag zu entscheiden.
  • Formuliere deinen Vorschlag schriftlich und lasse ihn während der Entscheidung sichtbar.
  • Unterscheide die Rückmeldungen aus der Gruppe nach Verständnisfragen, Reaktionen oder echten Einwänden.
  • Hinterfrage die Einwände hinsichtlich ihrer Relevanz und frage dich gemeinsam mit dem Einwandgeber, wie diese in den Vorschlag integriert werden können.

Unsere Erfahrungen mit dem IDM haben wir kürzlich im Rahmen der Berlin DoSE bei der Pecha Kucha Night von IS24 vorgestellt. Offenbar ist das Thema nicht nur für uns relevant denn wir haben sehr große Resonanz erfahren und nebenbei mit unserem Vortrag auch den ersten Platz belegt :)

Microgames for Wetware Developers by Julia Dellnitz & Stefan Zörner

Hypoport invites you to an interesting GOTO Night with Julia Dellnitz & Stefan Zörner on behalf of GOTO Berlin.

The session will start at 7PM on July 2, 2015 at our headquarter Klosterstr. 71, 10179 Berlin. Please come by and give them a visit. Food and Drinks will complement the session.

Microgames are small decoupled learning entities about a specific topic such as software architecture. They help teams and companies to get up to speed in a specific field and can easily be integrated in their daily practices. Microgames implement the idea that the wetware of our brain develops best when we are alert, link our learning to our day-to-day work, learn with positive emotions and distribute small learning units over time.

Julia Dellnitz (Learnical) and Stefan Zörner (embarc) will provide a playful and interactive session with findings from neuroscience and practical examples from software architecture.
Join us and be ready to play!


Julia Dellnitz creates playful and interactive learning formats. Her passion is to support experts in developing and implementing innovative (IT-) products and processes. She has managed large change and IT implementation initiatives over the last decade and has worked with over 4.500 people on learning and innovation topics – especially in international contexts.
