I gave three LJC lightning talks in May 2020
In the spring of 2020, the London Java Community (LJC) started hosting online lightning talks every other Friday. I was honored to give three lightning talks there in May 2020:
- The first talk was “Eclipse OpenJ9: Memory Diet for Your JVM Applications”. Eclipse OpenJ9 is an alternate JVM. It uses less memory, especially in containers. It therefore lowers the cost of running your Java applications.
- The second talk was “Google Jib: Smaller & Faster Docker Images for Java Applications”. Google Jib creates layered Docker images for Java applications. With these images, you usually push 90%+ less data to your Docker repository. So Jib saves a ton of time & network bandwidth!
- The third talk was “Better Spring Boot Projects Faster With JHipster”. JHipster is a Java application generator and generates full Spring Boot monolith or microservice applications. So JHipster saves you time when you learn and when you manage your project and your code.
Java Tech Popularity Index Q4/2023:
