@cl4es @kartik_1712 Good thing is you can follow and talk with your whoever regardless of the servers they are on.

@cliff_click And we’re actively hiring for Java on RISC-V (remote and in-office, PT to CST time zones). DM if you liked the discussion and are interested. jobs.lever.co/rivosinc/a1104…

I can’t support how this platform is turning, we don’t need more safe havens for extremists. You can find me at @ludovic_dev" target="_blank" rel="nofollow noopener">mastodon.social/@ludovic_dev

Happy to see the vectorization of string and arrays hashCode picked up by @cl4es. An up to 6 times speed improvement in some hashCode heavy workloads (building indexes out of HashMap for example) github.com/openjdk/jdk/pu…

Welcome @alexsnaps to speak at #Jfokus 2023! Happy to have you back in Stockholm! Alex will speak about Rust, check it out jfokus.se/talks/1104 #conferenceseason

Project Panama has been developed for years and not GA yet. How about a library for fast native calls with no JNI overhead built in two nights? :) It works with existing JDK 11+ and can replace deprecated Critical Natives. github.com/apangin/nalim

Great to be back at conferences after such a long time, thanks @DevoxxMA! It was good to see friends and get to meet new ones.

Oh yeah, my kind of talk...with assembly dumps! #devoxxma @ludovic_dev

Last talk of the conference for me, I'll learn about the JDK 16 vector API thanks to @ludovic_dev at #DevoxxMA. JRuby will leap to JDK 17 at some point...I think Rubyists can benefit from vectorized operation, no?

Interesting live coding #java #vector api #hardwareacceleration @DevoxxMA

Running some OpenJDK tests on RISC-V and AArch64 on GitHub. Using Qemu until we get proper hardware. Excited! github.com/rivosinc/jdk/a…

Can't wait to get my hands on some RISC-V boards to get some CI for the OpenJDK up and running!

JDK 19 is out! Very excited about the RISC-V port! Now, unto working with OpenJDK vendors to make it easily accessible. jdk.java.net/19/release-not…

SIMD? There’s a Java API for that… if you’re attending @DevoxxMA I’d recommend adding this session by @ludovic_dev to your schedule devoxx.ma/speaker-detail…

Because we own the whole stack down to machine code, it's been a lot of effort to get @TruffleRuby onto M1. Almost there though! Builds on work by RedHat, Microsoft, Oracle, especially @lewurm. I'm just trying to merge it all together.
