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 AB.
At City Network I currently serve as Head of 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,
I work on this site in my spare time (which is also why articles
tend to appear here on weekends) and you should not mistake
anything on this site as official pronouncements of my employer. For
those, please head over to citycloud.com.
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 are write-ups of conference talks. Some articles are about how people work. Some are labeled Philosophy, though Ramblings might be a more appropriate tag.
Hey, can I ask you a favor? If you quote me by full name, I’d really appreciate if you got my name right. My surname is Haas, not “Hass”, and it does irk me a little bit when someone misspells my name to the thing that in my language refers to the worst and most useless emotion of all. Thank you!
