by At: FOSDEM 2019 https://video.fosdem.org/2019/UA2.114/new_interoperability_i18n_and_librelogo_improvements_of_libreoffice.webm 3 lightning talks about news and the most important experiences of the various LibreOffice developments made for migration projects in public administration and education, based on my recent presentations of LiboCon, Tirana, and our newer results. Building a LibreOffice development team: We have found and filed more than three hundred bugs during the biggest LibreOffice migration project of Hungary. Our help desk service couldn't handle these efficiently using half measures...

Imagine if you had Prometheus for log files. We will talk about Tempo, our attempt at creating just that.

The OWASP top 10 most critical web application security risks report published that insufficient logging is one of the top risks security teams face today. In this talk, we will go through issues with incident response teams without centralized logging as well as other reasons to do centralized logging (if you need more!), brief intro about structured data as well as configuration and output examples using NXLog Community Edition. This talk is aimed at administrators...

The Retro-uC was a crowdfunding campaign for an open source silicon project. One of the reasons the campaign did not attract enough people was a lack of enough attractive features. The feature set was kept minimal to allow a first time right chip production. The choice of HDL is important to allow to implement more features with enough productivity and without increasing the risk of having buggy silicon. As will be presented, the venerable VHDL...

Ever tried developing Java applications in containers? Of course not. You're a sensible person. From a small footprint to a super-fast spin-up time, the reality of containers is a far cry from the reality of an OpenJDK binary execution. So how do we bring these two disparate visions closer together? Simple! We jlink the required JDK modules to generate a smaller footprint, then leverage alternate JVMs for performant startup! I promise, the reality is simpler...

Java has evolved significantly in the past 20+ years. Users still want to run highly scalable monolithic applications, but now they also want to run in the cloud with fast startup and small footprint. Checkpointing will solve at least half of that problem. I'll show you how to checkpoint your java application and then restore it on a different machine, or several different machines. An application that might take minutes to warm up, can be...

Wir stellen hier das Graswurzel-Netzwerk "Tutorials in Bibliotheken" vor, welches sich im März 2021 gegründet hat. Ziel unserer Community ist es, in Bibliotheken tätige Menschen zu vernetzen, die Tutorials bereits erstellen bzw. sich für deren Erstellung interessieren. Die Themen umfassen den vollständigen Zyklus von Planung, Erstellung, Verbreitung und Evaluation von Tutorials. Konkret werden z.B. Konzepte, Didaktik, Programme/Plattformen, technisches Zubehör, Veröffentlichung und Verbreitung besprochen. Neben dem Wissenstransfer innerhalb der Community öffnet sich das Netzwerk auch nach...

Der Dokumentarfilm gibt einen Einblick in das Lehrkonzept des Göttinger Physikers Robert Wichard Pohl (1884-1976). Der Schwerpunkt liegt auf der Verwendung von Pohl-Ideen und -Apparaten in der modernen Grundvorlesung zur Experimentalphysik in Göttingen. Es wird die Arbeit der Dozent:innen und Hörsaaltechniker vorgestellt und von Ihnen in Interviews kommentiert. Der Film entstand im Rahmen des Forschungsprojektes "Projektionen. Die Lehrsammlung Robert Wichard Pohl" (2020-2022, finanziert aus dem Förderprogramm PRO*Niedersachsen)
