Last weekend, I attended FrOSCon 14 in St. Augustin, Germany. I gave a presentation about “Managing and Monitoring Ceph with the Ceph Dashboard”, where I gave an overview and update about our work on the Ceph Dashboard, including a live demo.
Sadly, my poor little laptop ran out of resources near the end of the demo, so I could not fully conclude my presentation. But I hope the session was still worthwhile!
If you haven’t been able to attend it, I just uploaded the slides and the video recording is also available already. I’d like to say a very big “Thank You” to the video crew that performs the video recordings and post-processing, I was very impressed by how quickly they published them! Enjoy!
Last weekend, I traveled to the beautiful city of Brno in the Czech Republic, to attend at speak at the DevConf.CZ open source conference. I had submitted a talk about our ongoing work on the Ceph Manager Dashboard and was very happy that it got accepted, as I haven’t been to a DevConf before.
The conference took place in the lecture halls of the Faculty of Information Technology at Brno University of Technology, which provided a very nice venue with lots of rooms and infrastructure (the WiFi was a tad bit slow, but usable). Still, some talks were so popular that the rooms were full and the session chairs had to block others from entering (something that other conferences like FOSDEM also suffer from). Fortunately, many of the sessions were recorded, so there is an opportunity to watch them later.
The overall organization of the conference was excellent, the organizers had really thought of everything and it was a pleasure to attend this event from a speaker/participant point of view. There was a cloak room, badges that clearly indicated your preference of being photographed or your preferred level of engagement in conversations with other attendees. Food was also available in good variety (both free and several paid-for additional options provided by food trucks). The organizers had also set up a group chat on Telegram, which was used to spread information to all participants quickly.
The session schedule was packed and I had a tough time to choose which ones to attend. I ended up with attending the following sessions:
Growing Your Career: From Tactical to Strategic — The topic sounded interesting, but I only attended this panel discussion for about 20 minutes, as it was too painful for me to watch how a single lapel microphone was frequently handed over from one panelist to another one so they could be heard. Even a handheld mike would have been an improvement…
A Greybeard’s Worst Nightmare — in this session, Daniel Riek summarized the pains of packaging modern applications, the proliferation of custom solutions for distributing software and libraries and how they could be addressed in the modern world of container technologies. Good food for thought, it certainly resonated well with some experiences we have been going through in the openATTIC and Ceph Manager Dashboard project.
Open leadership: An invitation to all — this presentation resonated very well with me and I was able to capture a number of good ideas on how to improve my own skills. I liked the style of this session, which was more an open conversation than a head-on presentation. To my knowledge it wasn’t recorded, but the slides are worthwhile checking out.
Ceph data services in a hybrid cloud world — Sage Weil, founder and lead developer of the Ceph project talked about the challenges of syncing and moving data across multiple clouds and explained some of the existing and future solutions that Ceph brings to the table to resolve these. I found this session very insightful and it was interesting to learn more about the project’s future plans in this area. I guess our work on the Ceph Manager Dashboard isn’t finished any time soon!
Active/Active NFS Serving over CephFS — Jeff Layton gave a very detailed into his work on making it possible to set up NFS services based on NFS Ganesha with CephFS on the backend in a scalable way, this was very insightful (see his blog post for an example on how to set this up). Unfortunately his live demo failed during the presentation with processes getting stuck, but I actually saw the demo before his session and it certainly impressed me!
Unfortunately I could only attend the conference on Saturday, as I was traveling to and back from the event by train on Friday and Sunday. I wished I could have stayed for more! I will definitely plan to go back there some time.
I took a few pictures during the event, which can be found on Flickr :
A while ago, I concluded my first year in the openATTIC-Team at it-novum. We’ve gone through a lot of changes and I am quite proud of what we’ve achieved so far. In many ways, we’re starting this project and product from scratch, and I’m excited to be able to contribute to this effort with my experience from past jobs, and to help shaping the future direction. I feel grateful for having a very enthusiastic and supportive team. It’s also quite satisfying to observe how the seeds that we planted slowly come to fruition, as the project begins to gain traction with a growing user base and developer community.
Last week, I attended the 13. Kieler Open Source und Linux Tage (KieLux) in Kiel, Germany, to give a presentation (in German) about “Flexibles Storage Management unter Linux mit OpenATTIC” . I had an audience of ~25-30 people, a video recording of the session (in 4K!) will be published shortly. I had a great time at KieLux and learned a lot in the other sessions I attended. It was also nice meeting new people and touching base with long-time acquaintances again. Thanks to the KieLux organizers for arranging this event and for inviting me!
My slide deck is now available from SlideShare. Enjoy!
Today, I’ve started a new chapter in my career: I’ve left TeamDrive Systems after 1.5 years and joined it-novum in Fulda, where I will be responsible for their open source storage solution openATTIC as a Senior Product Manager in their infrastructure group.
