Really great to see plans for adding better integrated support for running @graalvm.org language implementations for JavaScript, Python, and WebAssembly in your Spring applications! github.com/spring-proje...

Oh, the outfit for my „AI-related“ Swiss Dev Confederation keynote about @graalvm.org and @quarkus.io just dropped...

For my keynote with @sannegrinovero.bsky.social from at www.redhat.com/en/events/de..., I am experimenting with @graalvm.org native image, @kotlinlang.org, and @quarkus.io and it works great! Instant startup, low memory footprint, and high throughput. Check it out here: github.com/thomaswue/na...

Difficult to top the last one, but definitely looking forward for another @graalvm.org session together with @starbuxman.joshlong.com! See you at @devoxx.com Belgium in November!

Really great to see that @apache.org Kafka is releasing also a @graalvm.org native image compiled version of their docker images. The native docker image "apache/kafka-native:4.0.0" is not only 3 times smaller, the startup is also around 5 times faster! 🚀🏆 kafka.apache.org/downloads

Super excited to be this year for the first time at Spring I/O in Barcelona talking about @graalvm.org 🏆 and Spring with @starbuxman.joshlong.com! Expect a session with some energy that demonstrates why native image is awesome for your Spring applications 😉.

Looking at the @graalvm.org build report of a native image "helloworld" that includes all locales shows an artistic picture with thousands of classes named CurrencyNames_* or TimeZoneNames_* or LoacleNames_*. For AOT compilation having this static data represented as code is not great.

The DeepSeek-R1 LLM model really nails the differences between JIT and AOT compilation. The comparison table is concise and accurate and shows the primary advantages of AOT compilation of Java programs via @graalvm.org native image.

Concluding 2024 with moving all Twitter data to my own web server and cleaning up the account. The archive with top tweets from 2014 to 2024 is a fun walk down memory lane with highlights of the evolution of the @graalvm.org project. Happy New Year everybody! thomaswue.dev/twitter/arch...

Sorting out old books, I stumbled over this gem. Got „The Algorithm Design Manual“ from Steven S. Skiena as a present in 2002 and it was highly useful for developing algorithmic skills. Would highly recommend the new edition from 2021 to anyone who wants to advance in this area (also for experts)!

Hate to post about politics (and promise to do it only on very rare occasions), but I think it is important to know that this person is trying to influence and interfere with German elections next. Presumably he wants to own that government too.

On X there are 3 tiers where people can pay for a "small", "larger", or "largest" reply boost. This turns replies into ads that are ordered by how much one is willing to pay. I hope that @bsky.app introduces a subscription to keep the platform ad free, but does not prioritize content based on that.

This statement from the paper is of course wrong on many levels. Truffle runs on any JVM and also standalone in a native library via @graalvm.org native image without even a Java runtime present.

And while the quickly hacked up monolith is still standing, the carefully modularized sculpture has already issues with dependencies 😉
