Location: Leipzig, Germany

The theme: SAPUI5 / UI Development Toolkit for HTML5

Some local history: (source Wikipedia)

Leipzig is the largest city in the federal state of Saxony, Germany. With a population of 570,087 inhabitants, it is Germany's tenth most populous city.

Leipzig is located about 160 kilometers southwest of Berlin.

Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and Via Imperii, two important Medieval trade routes. Leipzig was once one of the major European centers of learning and culture in fields such as music and publishing.

Since the reunification of Germany, Leipzig has undergone significant change with the restoration of some historical buildings, the demolition of others, and the development of a modern transport infrastructure.

Leipzig today is an economic center and the most livable city in Germany, according to some marketing research institution.

And with Christmas approaching, this is how it looks like this days.

Our host: Arvato Systems

Arvato is a subsidiary of Bertelsmann. With approximately 70,000 employees across 40 countries, its services include customer support, the development and execution of customer loyalty programs, financial transaction processing and logistics.

Arvato also offers logistical services, such as consulting, procurement/purchasing, order management, production, repair services and warehousing.

The history of arvato began over 175 years ago, when Carl Bertelsmann opened a lithographic printing shop in the East Westphalian town of Gütersloh. This was the first step in the development of a corporate division that today accounts for more Bertelsmann employees than any other.

The business began by printing and shipping books and other printed materials for Bertelsmann’s publishing companies, then expanded to provide services for external customers. This marked the birth of arvato, which subsequently grew larger, became involved in new industries, developed innovative products and expanded into other countries and continents − until it became what it is today.

Our host daniel.lippmann5 is from the Arvato Systems Perdata.


The audience:

Most participants where from Arvato IT with only few external people. The level of expertise varied from complete beginners to really experienced developers (and really above my level I have to admit :-)).
I have several really interesting and challenging question like:
- "I'm using SAPUI 1.26 but my customer wants to use the latest icons from 1.40. How do I do that?" and here was an answer:

- "how do I make sure my control library is not loaded everytime I open my control?" which I had a hard time finding an answer. It seems that the Comopnent-preload.js might help:

Performance Improvement with Component-preload.js

The goals:

During the CodeJam, we provided access to useful online information, exercises and tutorials but also guidelines regarding the set of tools to use with the SAP HANA Cloud Platform and SAPUI5 and to build an application.

One key aspect of the session was not only to provide the audience with tips and tricks regarding the technology and the tools but also around common errors and ways to debug problems.

The networking:

As stated before, a CodeJam is not successful unless the attendees manage to code and deploy an app and also share their knowledge and experiences around SAP and other technologies.
