FOSDEM 2021 and Java DevRoom
by Mario Torre 30 Oct '20

30 Oct '20

Hi all, I hope this email finds you well. As you probably know, the next edition of FOSDEM will be a fully online conference and the CFP is now open for the DevRoom to register and will close in just a couple of days. I've been thinking a lot about this, and I don't think the format suits us well. One of the most important aspects of the Java DevRoom is the face to face meetings and discussions that happen in the corridors and during the dinner, the content has a rather fair share of significance (otherwise we wouldn't do it!) of course, but the human contact the value of our DevRoom in particular (in a context as fantastic as FOSDEM) is what has made Java progress over the years, tied relationships and created new sources of discussion. There's of course also the aspect of helping the conference deliver great content, after all we have been part of FOSDEM for years, it wasn't just a place where to go for our own stuff detached from the rest, and for that I am grateful to the organisers. For this reason, rather than unilaterally decide about this and in the spirit of Open Source I would like some comments. For full transparency, I do think we should pass this round.

Accepted speakers!
by Mario Torre 19 Dec '19

19 Dec '19

Hi all, First of all, this has been the most difficult selection ever in the history of our devroom. There's just so much space and we could easily fill 3 days with great quality content. Unfortunately this means an higher than average ratio of talks that had to be rejected but this has nothing to do with the quality of the presentations or the speakers, in the end we tried to do a balancing based on the historical focus of the Java DevRoom, and I think we managed this. Without further ado, here is the selection for this year, with the tentative schedule: 10:30 - 11:15 State of OpenJDK 11:20 - 11:45 Project Loom: Advanced concurrency for fun and profit 11:50 - 12:15 TornadoVM: A Virtual Machine for Exploiting High-Performance Heterogeneous Execution of Java Programs 12:20 - 13:00 ByteBuffers are dead, long live ByteBuffers! 13:05 - 13:30 Free at Last! The Tale of Jakarta EE 13:35 - 14:00 Shenandoah 2.0 14:05 - 14:45 JMC & JFR - 2020 Vision 14:50 - 15:15 Hacking on GraalVM: A (very) Rough Guide 15:20 - 15:45 Reducing OpenJDK Java Garbage Collection times with stack allocation 15:50 - 16:15 G1: To infinity and beyond 16:20 - 16:45 Just-in-time compiling Java in 2020 16:50 - 17:15 Helpful NullPointerExceptions - The little thing that became a JEP 17:20 - 17:45 Taming Metaspace: a look at the machinery, and a proposal for a better one 17:50 - 18:15 The OpenJDK JVM : Securing a moving target or What could possibly go wrong? 18:20 - 19:00 JRuby Startup and AOT I want to thank each of you personally for sending such an impressive quality of proposal.

Talk proposal: ByteBuffers are dead, long live ByteBuffers!
by Maurizio Cimadamore 13 Dec '19

13 Dec '19

Title: ByteBuffers are dead, long live ByteBuffers! Abstract: Direct buffers are, to date, the only way to access foreign, off-heap memory. Despite their success, direct buffers suffer from some limitations --- stateful-ness, lack of addressing space, non-deterministic deallocation to name a few --- which makes them a less-than-ideal choice under certain workloads. In this talk we paint the path to the future: a safe, supported and efficient foreign memory access API for Java. By providing a more targeted solution to the problem of accessing foreign memory, not only developers will be freed by the above limitations - but they will also enjoy improved performances, as the new API is designed from the ground-up with JIT optimizations in mind - and all without sacrificing memory access safety.
