I’ve worked pretty much exclusively with open source software since about the time I graduated from college in 2003. I worked at a small outfit out of Vienna called ADS-System, which was then acquired by Kapsch BusinessCom. I then went to work for LINBIT for about 4½ years, and co-founded hastexo with my partners Martin Loschwitz and Andreas Kurz in 2011. We parted ways 3 years in, and 3 years after that I sold hastexo to City Network Hosting AB.
At City Network I currently serve as VP Education, and I am also the
MD of City Network Education Services, the legal entity formerly known
as hastexo (the hastexo brand is defunct). Some of the content on this
site was originally hosted on
hastexo.com, was not carried over onto
the City Cloud web site, and I’ve resurrected it here based on popular
demand and for reference purposes. Such content is clearly spelled out
as such at the bottom of the respective pages. Regardless, you should
not mistake anything on this site as official pronouncements of my
employer. For those, please head over to
citycloud.com, where I also contribute to
the City Cloud blog.
Most of the articles on this site cover technical issues, largely around OpenStack, Open edX, and Ceph — but there’s also a sprinkling of Python content and other topics. Some articles are not technical at all, I’ve labeled those Philosophy, though Ramblings might be a more appropriate tag.
