I can’t support how this platform is turning, we don’t need more safe havens for extremists. You can find me at 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)

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 – at Taghazout, Royaume du Maroc

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? – at Taghazout, Royaume du Maroc

Running some OpenJDK tests on RISC-V and AArch64 on GitHub. Using Qemu until we get proper hardware. Excited! github.com/rivosinc/jdk/acti…
JDK 19 is out! Very excited about the RISC-V port! Now, unto working with OpenJDK vendors to make it easily accessible.

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

As developers, we tend to be excited the most about new language features; and while #Java does deliver there, I think the real game changer are all the runtime improvements currently being worked on: virtual threads, native integration, SIMD support, primitive classes, etc.

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.
