A few weeks ago, I had the chance to be at Devoxx Belgium once again, to meet developers and learn about new things from awesome speakers. Google Cloud Platform had its own booth on the exhibition floor, and the team was running codelabs: 10 laptops were at the disposal of attendees to go through various hands-on tutorials on several GCP products. I took a chance at crafting my own codelab: deploying a Micronaut application, containerized with Jib, to Google Kubernetes Engine.

Just before heading to Google Cloud Next, I was notified I was listed 4th in JAX London’s Top 20 Java influencers of 2018 on social media! It’s an honor to be listed among famous figures like Josh Bloch, Brian Goetze, Martin Thompson, Arun Gupta, Jessica Kerr, Mario Fusco, Josh Long, Venkat Subramanian, Charles Nutter and many others. You can see the full list of the top influencers here.

I’ll definitely continue to advocate for Java (and Apache Groovy) developers around the world, and share whatever I learn along the way through articles or conference talks. I’m looking forward to meeting you, my fellow Java/Groovy developer friends, at an event near you.

The Java Champions recently nominated me to become a Java Champion!

There’s also a post on the Java Champions’ blog, and InfoQ also echoed the new nominees recently.

I’m super happy and proud of this nomination, and I’m looking forward to continuing being involved in the Java ecosystem, present at Java-friendly conferences, contribute to Open Source projects using Java and Apache Groovy, and write articles here and there using my favorite languages.

In my timeline, I saw a tweet from Joe Walnes about the built-in HTTP server available in the JDK since Java 6. It’s super convenient, starts super fast, easy to use, but I often forget about it. I’d probably not use it for serving planet-wide load, but it’s very useful when you need to create a quick service, a little mock for testing some web or micro-service.

Here’s a little hello world for the fun.

Last week, I was in San Francisco for my tenth JavaOne! I had two sessions: one on the past / present / future of Java Platform-as-a-Service offerings, and one on programming language influences, and particularly how was Apache Groovy influenced, and how it also inspired other languages.

Here’s the abstract:

Languages have been influencing one another since the dawn of computer programming. There are families of languages: from Algol descendants with begin/end code blocks to those with curly braces such as C. Languages are not invented in a vacuum but are inspired by their predecessors. This session’s speaker, who has been working on Apache Groovy for the past 14 years, reflects on the influences that have driven the design of programming languages. In particular, Groovy’s base syntax was directly derived from Java’s but quickly developed its own flavor, adding closures, type inference, and operators from Ruby. Groovy also inspired other languages: C#, Swift, and JavaScript adopted Groovy’s null-safe navigation operator and the famous Elvis operator.

I’ll be back at JavaOne in San Francisco in October to speak about Apache Groovy and Google App Engine.

Apache Groovy

I’ve been involved with the Apache Groovy project for 14 years now, it’s a long time, and it’s interesting to see how the language has evolved over time, how it was influenced by other languages, but also how it influenced those other languages itself! Let’s see which operators or syntax constructs evolved and moved from one to the other.

Apache Groovy is coming up with a new parser, that supports the Java 8 syntax elements, as well as some new notation and operators of its own (like !in, !instanceof or ?[] for safe navigation with collections, or with ?= for Elvis assignment). I blogged recently about the fact that you can try this new flavor online on this forked Groovy Web Console version, without the need of installing everything. But today I’ll tell you how to build it for yourself in order to run it on your machine.

In two weeks, I’ll be flying east, much further east than I’ve ever been! I’ll visit Singapore! And I’ll have a pretty busy week with several events: conference, meetup, user groups, brown bag lunch… and I’ll talk about Groovy, Machine Learning, and chatbots!

First of all, on Wednesday 31st, I’ll participate to the Singapore Java User Group, where I’ll give an update on Apache Groovy (the latest improvements, new features, the roadmap).

A new Java 8 runtime for Google App Engine standard is coming soon, and is currently in alpha testing. You can request to join the alpha program, if you want to try it out for yourself. But I wanted to let anyone play with it, easily, to see how well the Java 8 APIs work, but also to try some Java 8 syntax too. So here’s a web console where you can do just that!

After some trouble getting to San Francisco because of strikes, transportation issues, burnt control tower, and more… I managed to land to JavaOne! I missed my own first talk and I was glad and grateful that Cédric could present it for me.

At JavaOne, the Groovy project received the award from ZeroTurnaround / RebelLabs, for the “Best Tech - Geek Choice Award” :

Youpi mon projet a reçu un prix de l’innovation ! Très fier de ce que mon équipe a accompli !
