    DevBcn Report, Part 2 – Spanish Knowledge Sharing (#77)
    Jul 26 2025

    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!
