There really should be an official JVM Appreciation Day, where we give our JVMs some tea and a massage.
The Virtual @OpenJDK Serviceability Meetup 2025 will be the 17th of December: mail.openjdk.org/pipermail/serv…
WOW 🤩 The OpenJDK Vector API improvements to the JRuby JSON lib now improve encoding perf by better than 2X on real-world benchmarks, all without writing a line of assembly code! The potential of JRuby to accelerate Ruby apps grows with every JVM release. buff.ly/yKE2nfq
JavaOne 2025 was such a hit that we just have to run it back. 😎 Save the date for our next #JavaOne event, coming to you March 17-19, 2026! social.ora.cl/6011fdkbH
Oooh! @OpenJDK @javamissionctrl won the tools category! x.com/java/status/19… JMC 10 will have a lot of exciting features - including support for the new (proper) CPU profiler in openjdk.org/jeps/509. On behalf of the project - thanks for all the votes! :)
We’re ready to kick off the quarter-finals of the Best of Java Feature Face-Off! The matchups are getting intense as we inch closer to the finals. Place your votes now to see which features advance to the semi-finals! #30YearsOfJava
Curious about open source? Join us in Switzerland on the 22nd of November for Hack-Commit-Push - a full day of hands-on OSS fun, no prior experience needed! Great chance to contribute, learn & connect. switzerland2025.hack-commit-pu.sh @Hackergarten @OpenJDK @javamissionctrl
Hej @kstefanj! Regarding what we talked about at @JavaOne, this might help: github.com/openjdk/jmc/pu…
The @OpenJDK @javamissionctrl 9.1.0 source release is now available: github.com/openjdk/jmc/re… Here is what's new: hirt.se/blog/?p=1561
Congrats to Hendrik Schick on his first @OpenJDK @javamissionctrl contribution: github.com/openjdk/jmc/pu… Also thanks to the excellent @hackcommitpush initiative that enabled it: switzerland2024.hack-commit-pu.sh
Would you like to contribute to an open source project, but don't know how to get started? Or would you just like to join in on a fun day of coding? On Saturday I'll be at Hack-Commit-Push Switzerland: lnkd.in/dEdxnnkp Hope to see you there!
Datadog is indeed fantastic! Prometheus and grafana are fine, but compared to datadog it feels like banging rocks together 😄
Datadog has a reputation to provide the best, but not the cheapest products. However, one aspect that is easy to forgot is that good observability empowers engineers to significantly optimize cloud cost. Learn how dogfooding our own products is saving us huge amounts of money.
Over a two-month period, our engineers recorded 15 performance optimizations that saved us $17.5 million in annual cloud spend. Learn how we dogfood different products and build our FinOps culture at Datadog: dtdg.co/cost-savings
What's new in JDK Mission Control 9? Take a look at some of the key changes with @BillyKorando. social.ora.cl/6010jUvBE
The new timeline view in Datadog Continuous Profiler gives you a detailed chronological visualization of multithreaded activity, helping you pinpoint causal factors behind non-parallelization and other runtime performance issues more easily. Read more: dtdg.co/timeline-view

Diagnose runtime and code inefficiencies in production by using Continuous Profiler's timeline view...
Learn how you can use Continuous Profiler’s new timeline view to investigate the causes behind application performance issues.
The @datadoghq Continuous Profiler always improves datadoghq.com/blog/source-co… docs.datadoghq.com/profiler/conne… Note there’s also a plugin for @IntelliJIDEA & other JetBrains IDEs with a simpler integration, plugins.jetbrains.com/plugin/19495-d…. If you are using Continuous Profiler, send feedback (TY).
Go の Continuous Profiler、Datadog をよく聞きますね。 というか Datadog しか聞かない。 GoCon2024 でも Kanmu の方が話していて、それもprofile data を Datadog から取得してた。 これだ → gocon.jp/2024/sessions/… #layerxgo
Datadog Continuous Profiler is just amazing 👌🚀 If you are using DDOG, but not profiling, just go enable it, now!
One of my favorite features of the Continuous Profiler we're building at @datadoghq is Custom Context. It allows you to break down your resource consumption, like CPU usage, by any dimension. You can add anything you want: Customer ID, Rule ID, Country, etc ...
