Talk proposal: Ecosystem Stewarship, Revisited
by Dalibor Topic 11 Dec '19

11 Dec '19

Title: Ecosystem Stewarship, Revisited Abstract: Keeping Java a favorite choice for millions of developers doesn’t happen by accident; careful stewardship is needed to keep up with rising challenges and developer expectations. But good stewardship doesn’t only mean having a compelling technical roadmap — it also means keeping the community and ecosystem vibrant. Not all of it is obvious and not all rumors are true, so this talk is going to shine a light onto what the Java team at Oracle has done for us, lately, in OpenJDK and beyond, with curious charts and cute comics. * Recording me on audio and/or video acceptable under a CC-BY-2.0 license * Brief Bio Dalibor Topic lives in Hamburg, Germany, and works as Consulting Product Manager for Oracle. He joined the OpenJDK project in order to help make it a successful open source project, and stayed for anchoring Java in Linux distributions, and as an all around Java F/OSS community guy. He joined the Java strategy team at Oracle to help provide community feedback into the long-term strategy planning. * Twitter: @robilad cheers, dalibor topic -- <http://www.oracle.com> Dalibor Topic | Consulting Product Manager Phone: +494089091214 <tel:+494089091214> | Mobile: +491737185961 <tel:+491737185961> | Video: dalibor.topic(a)oracle.com <sip:dalibor.topic@oracle.com> Oracle Global Services Germany GmbH Hauptverwaltung: Riesstr. 25, D-80992 München Registergericht: Amtsgericht München, HRB 246209 Geschäftsführer: Ralf Herrmann <http://www.oracle.com/commitment> Oracle is committed to developing practices and products that help protect the environment

* Title: How to become an OpenJDK contributor * Abstract: Any and every developer can engage in the OpenJDK project and be part of improving the Java experience. There are many ways to contribute to OpenJDK. One of the more obvious ones is probably to participate in the design and development of language and runtime features. This talk will guide you on the road to become an active contributor to OpenJDK. We will go through all the steps from idea to contribution and look at how to actually contribute in practice. We will have a brief look at the structure behind the OpenJDK project and how to utilize the tools that are provided to aid the work. * Recording me on audio and/or video acceptable under a CC-BY-2.0 license * Brief Bio Jesper is a developer in the Java Platform Group at Oracle. With a 17 year history in the JVM and garbage collection his focus today is in areas such as JDK wide process management, JVM security, JDK integrations, early access promotion, and overall JDK stability. Jesper has authored large parts of the HotSpot engineering pages on the OpenJDK wiki. Best regards, /Jesper

Free Java DevRoom Talk Proposal: JMC & JFR - 2020 Vision
by Jie Kang 10 Dec '19

10 Dec '19

Hi, Title: JMC & JFR - 2020 Vision Abstract: JDK Flight Recorder provides production time profiling and diagnostics via a compact events-based infrastructure inside the Hotspot JVM itself. JDK Mission Control is a stand-alone application that provides real-time monitoring information for Hotspot JVMs, as well as tools to read, automatically analyze and visualize flight recording data produced by JDK Flight Recorder. When this talk is presented, JMC 7.1.0 has (hopefully) been out for a little while. This presentation talks about what is new and the roadmap for the upcoming JMC 8. We will also discuss recent changes in the project, such as the move to Skara. Towards the end we will demo how JDK Flight Recorder and JMC core libraries can be used to diagnose applications deployed in container orchestration platforms. Recording: Okay Presenters: Jie Kang (Red Hat) Speaker Bio: Jie Kang is a Senior Software Engineer in Red Hat’s Java team, mostly working on JMC and JFR related technologies. This includes cloud-related tooling, packaging for RHEL and Fedora and backports of JFR patches to 11 and below. Regards, Jie Kang

Proposal: JRuby Startup and AOT
by Charles Oliver Nutter 05 Dec '19

05 Dec '19

Title: JRuby Startup and AOT Abstract: Rubyists work from a command line, which makes JRuby startup time a critical concern. Traditionally, the JVM has not been optimized for startup, but that's changing. This talk will explore all available options for making a heavy runtime like JRuby start up quickly, from using class data caching services like Hotspot's CDS and OpenJ9's Quickstart to ahead-of-time compilation of JRuby using GraalVM's Native Image. We'll compare approaches and trade-offs. Notes: We will only be exploring and discussing the open-source parts of GraalVM (and any other tools we include). This talk will be presented by Charles Oliver Nutter and Thomas Enebo - Charlie

Free Java Advanced Imaging
by Jody Garnett 02 Dec '19

02 Dec '19

I just noticed this dev room when following up on the geospatial dev room extended deadline. This group would be AMAZING to share some exciting work I have been doing on my own time (after failing to attract funding for years...) So yeah, because this is a perfect fit for this group, and because I really want to see this rescue effort succeed please consider the following talk for any waitlist. -- Jody Garnett *Title:* ImageN and the quest to free Java Advanced Imaging *Abstract: * The Java Advanced Imaging is a powerful Java image processing engine powering a wide range of applications including the mapping applications (GeoServer, GeoTools, GeoNetwork) I work with day to day. This talk explores: - Core capabilities that make JAI attractive - Success of JAI architecture for geospatial work - Working with the Eclipse Foundation and Oracle to “Free” the JAI project - The Eclipse ImageN library One of the reasons our community has been so addicted to this library is its power. It explored concepts like parallel processing, and distributed parallel processing in 1999, well ahead of the curve. It is an excellent example of engineering and software design. Tragically there has been one problem with this ... the JAI library is not open source! The library originated at Sun Microsystem as a core component of the Java Runtime Environment, but was not included as part of OpenJDK collaboration. We will cover the search for an open source alternative, and the exciting progress made thus far. Come see how this foundational library is being propelled into an open source future by our community. I really hope to attract passionate Java developers who understand the importance of making this neglected part of the JRE free for our developer community. *Recording me on audio and/or video* CC-BY-2.0 license is fine (Prefer CC BY ATTRIBUTION if available). *Brief Bio: *Open source geospatial contributor with Open Source Geospatial Foundation and Eclipse Foundation LocationTech working group. Projects include GeoTools, GeoServer, JTS Topology Suite, ImageN and uDig. *Microblog URL: *http://twitter.com/jodygarnett *Blog URL: *https://www.how2map.com
