I finally got around to write down my impressions and notes from the OpenStack Summit 2015 in Tokyo, Japan. You can find my conference report on the openATTIC blog. Enjoy!
In case you were wondering why there were so few posts on this blog in the past weeks: since we’ve set up a dedicated blog for openATTIC, a lot of my recent blogging activity has taken place there. You can find all my posts using the Posts by Lenz Grimmer view.
Back in September, I attended the Kieler Linux Tage, to talk (in German) about how to manage storage on Linux using openATTIC.
The presentation was recorded and the final result (in 4K) can now be viewed on YouTube. I hope you enjoy it!
Last week, 13. Kieler Open Source und Linux Tage (KieLux) in Kiel, Germany, to give a presentation (in German) about “. 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!
Last weekend, I gave a presentation titled “The Evolution of Storage on Linux” at this year’s FrOSCon 10 conference (Happy Anniversary!). In case you have missed it, you can find the slides and video recording below. Thanks to the FrOSCon team for having me, it’s always a pleasure to be there!
Unfortunately I had some technical issues in the beginning and was somewhat too ambitious with regards to the topics I wanted to cover, so I ran out of time. There is simply too much cool stuff happening in the storage space – but I hope that the audience still enjoyed it!

Back in the MySQL days, there was a need to have a contributor agreement that made it clear under which terms code contributions to the MySQL code base could be accepted. This was a requirement due to the dual-licensing model of MySQL, under which the software was available both under the GPL and a proprietary license.
This agreement was further refined when MySQL was acquired by Sun Microsystems in 2008, which resulted in the “Sun Contributor Agreement” (SCA), which was used for all Open Source projects that were sponsored/governed by Sun Microsystems (e.g. OpenOffice.org, Java, etc.).
The text of the agreement itself was licensed under a creative commons license (Creative Commons Attribution-Share Alike 3.0 Unported), and it was later used as the basis for contributor agreements of several other Open Source Projects, e.g. MariaDB or OwnCloud (even though both fail to give proper attribution to the original). In fact, the agreement still exists as the Oracle Contributor Agreement today, after Sun Microsystems was acquired by Oracle in 2010. If you would like to submit a patch to MySQL, you first need to get your name on the OCA Signatories List.
While doing some research on creating such a contributor agreement for openATTIC, I was pointed to this very useful resource: http://contributoragreements.org/
“Contributor agreements are agreements between an open source or open content project and contributors to the project that set out what the project can do with the respective contribution: code, translation, documentation, artwork, etc. The purpose of such agreements is to make the terms under which contributions are made explicit and thereby protect the project, the users of the project’s code or content, and often the contributors themselves. Contributor agreements provide confidence that the guardian of a project’s output has the necessary rights over all contributions to allow for distribution of the product under either any license or any license that is compliant with specific principles.”
The nice part about this web site: it provides a guided Contributor License Agreement Chooser that allows you to compile a custom agreement based on the requirements (e.g. Copyright assignment, Patent clauses) that you define, similar to the Creative Commons License Chooser, where you can select the terms and conditions of your license to be guided to the appropriate choice.
So in case your project needs a contributor agreement, please don’t re-invent the wheel and consider making use of this site instead! There are way too many custom agreements floating around already…
My new employer performed a short interview with me about myself, my role in the openATTIC team and my thoughts on Open Source. Hope you enjoy it!

Moving on
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.
I wanted to share a few queries I created for Atlassian JIRA, that help me to keep track of my activities (e.g. for a weekly report, or to keep track of issues I submitted to other developers) – maybe they are useful for you, too:
- “My issues reported last week”:
reporter = currentUser() AND createdDate >= startOfWeek(-1w) AND createdDate < startOfWeek() ORDER BY created DESC - “My issues resolved last week”:
assignee = currentUser() AND Status = Resolved AND updatedDate >= startOfWeek(-1w) - “Open issues reported by me”:
reporter = currentUser() AND assignee != currentUser() AND resolution = Unresolved ORDER BY createdDate DESC
