New meeting time for openSUSE zsystems
by Sarah Julia Kriesch 16 Oct '22

16 Oct '22

Hello together, then the next meeting will be the following Tuesday and we will keep the time at 18:00. I have expected some international New Joiners and I wanted to be friendly with the time. But it seems, that we are only German ones now. Best regards, Sarah ---------------------------------------------------------------------------------------------------------------------------------------------------------- Hello together, Sorry, that I had to cancel the last meeting because of so many IBM related conferences. I can say, that we have some interested new people for our team (from Open Source Day until the Academic Mainframe Consortium with the Mainframe Summercamp). In parallel, I have received a meeting at the university for Wednesday in the evening and it seems, that we have got new countries in our team. I want to suggest to switch from Wednesday to Tuesday. Then I need your feedback, which time zone you have got, that we can find a matching time for all of us. Thank you! Best regards, Sarah P.S. I want to suggest also, that we repeat our training sessions for knowledge sharing again.

knowlegde session cancelled today
by Sarah Julia Kriesch 21 Sep '22

21 Sep '22

Hello together, I have to cancel our knowledge sharing session today because some of us are at the Open Mainframe Summit today. In parallel, I want to announce that we had some success at the Open Source Day this year again. Asha from Sri Lanka wants to join our team. That is the reason, that we have to find a new time for our meeting. We are a distributed team in USA and Germany until now. I need the time zones of our SUSE people joining our meetings from time to time for finding a new matching time for all of us. Thank you! Best regards, Sarah

Semeru Runtimes are available for Java 8, 11, 17, 18 (for Open Edition) and for Java 11 and 17 (Certified Edition). Eclipse Temurin is a raw build of OpenJDK but not as well optimized for the s390x platform, particularly in the areas of startup performance and memory consumption. While available and certified by Eclipse, it is not the preferred option. > > Christian >
