This is the first Foojay podcast in Spanish. It's also the shortest one and the final of season 4 ;-) Jonathan Vila "highjacked" the microphone from Geertjan Wielenga (See episode 76, https://foojay.io/today/foojay-podcast-76-devbcn-report-part-1-learn-from-the-community/) during the DevBcn conference in Barcelona and interviewed a few of the participants for this first Spanish-only edition of the podcast.

Stay tuned and subscribe to the podcast in your favorite app or on YouTube. We're taking a short break and will be back in September with the launch of Java 25!

53:43 Conclusion

We are celebrating Java's 30th anniversary this May!

This is a very special anniversary episode of the Foojay Podcast! As we approach May 23rd, marking exactly 30 years since Java's first beta release in 1995, we're honored to present our first-ever single-guest format. But we have a very special guest for you: James Gosling, the creator of Java!

Join us for this exclusive conversation as we explore Java's beginnings, its revolutionary impact on the programming world, its continuous evolution over three decades, and James's insights on where the language is heading. From that groundbreaking beta release over "Write Once, Run Anywhere" to powering billions of devices worldwide, this is the story of Java, told by the man who started it all, the father of Java.

On April 25, 2020, Geertjan Wielenga published the first Foojay post. Yes, we are celebrating 5 years since the Friends Of OpenJDK website launch! Today, more than 1,600 posts are on the site, written by over 250 authors. And there is much more to discover within the Foojay world...

In this podcast, we look at how Foojay started with founder Geertjan Wielenga. We'll also hear from Gerrit Grunwald about how Foojay's Disco API has become part of your daily work without you realizing it. We also have several of our regular authors and podcast guests who share how Foojay has influenced them (and vice versa).

Thank you all for being part of the Foojay community, whether as a listener of this podcast, a visitor to the website, a user of the Disco API, or through any other touchpoint!

On April 3rd, the first VoxxedDays event in Amsterdam took place. VoxxedDays are tech events organized by local community groups, with support from the Devoxx team. Geertjan Wielenga brought along a camera and microphone and spoke with many of the attendees.

This is the first Foojay podcast ever to feature more than 20 guests! Geertjan asked the same two questions to many of conference visitors: “Tell us who you are and what excites you about the technology landscape?” and “What are two tips or insights you’d like to share?”

As you might expect, there's a lot of talk about AI and machine learning, but you’ll also hear about new Java features, profiling, open source, security, code reviews, and much more!

We serve you a podcast about the new Java version every six months.

Our regular guest, Simon Ritter, Deputy CTO of Azul, is known on social media as "speakjava." He is part of the OpenJDK vulnerability group, JCP executive committee, and expert group for the Java SE specification request so that he can share a lot of inside information with us.

In this episode, we are joined by Hanno Embregts, a Java Developer by day and musician by night. He publishes a post on Foojay with all the details of every new Java release and prepared a long description of all the new features included in Java 24.  

Let's see what this new release brings us...
