Welcome to my personal site. My name is Tobias Hofmann, I am an SAP employee and SAP Mentor. I’ll use this space primarily to blog about SAP related topics. This site is served from a Raspberry Pi from my home.

Why this site?

I used to use SAP Community Network as my primary blogging channel. I still publish my blogs there. In fact, most of the content here you find also there, but most probably in a shorter form, as SCN makes it somewhat difficult to post content with a few images in it. And here I have more control over my content.


My primary interest with SAP and my daily work tasks are related to SAP Portal, SAP Mobile Platform, Afaria and Fiori. In a more general aspect, they are Java, HTML5, mobility in general and hybird apps in special. Although I admit to not stop here as I am very much interested in topics around open source, Linux, portals (Liferay), and analytics (Pentaho, ElaticSearch, logstash, BIRT). In early 2000 I used to run my own Grid at home for encoding videos, using X86, SPARC as well as a Laptop as my home cluster. Today this would be called: private cloud.

What to expect

As the underlying hardware is a Raspberry Pi, do not expect a 24/7 uptime or super fast internet speed. I may turn off the Raspberry from time to time on a weekend for some maintenance tasks or be hit by a blackout (hey, its Brazil and Rio de Janeiro == Light after all).
