November 13, 2024July 31, 2023 Trisha Gee

I’m about to jet off on my sunny* summer holidays, so it’s a good time to leave you with my recommended reading and learning. Are they all my books and content? Yes. But I do have discounts and deals for them, so that’s something, right? Working With Code in IntelliJ IDEA (Online course) I’ve just … Read more

Front cover for the book "97 Things Every Java Programmer Should Know"

Preface to 97 Things Every Java Programmer Should Know The mind is not a vessel that needs filling, but wood that needs igniting. Plutarch What should every Java programmer know? It depends.

August 12, 2021 Trisha Gee

I've just seen JEP 416: Reimplement Core Reflection with Method Handles has been promoted to Candidate status ("Candidate: Accepted for inclusion in the OpenJDK roadmap"), and thought I'd find out a bit more about it.

Java 8 MOOC – Session 3 Summary

November 30, 2020August 4, 2015 Trisha Gee

Last night was the final get-together to discuss the Java 8 MOOC. Any event hosted in August in a city that is regularly over 40°C is going to face challenges, so it was great that we had attendees from earlier sessions plus new people too.

Java 8 MOOC – Session 2 Summary

November 30, 2020July 31, 2015 Trisha Gee

As I mentioned last week, the Sevilla Java User Group is working towards completing the Java 8 MOOC on lambdas and streams. We're running three sessions to share knowledge between people who are doing the course.

Java 8 MOOC – Session 1 Summary

September 20, 2020July 21, 2015 Trisha Gee

The Sevilla Java User Group is working together towards completing the Java 8 MOOC on lambdas and streams. As part of this, we're running three sessions during the course so we can, as a group, ask questions about the lectures, get help with the homework, and (if we're feeling very smart!) help people who may be struggling (or might not have watched the videos).

November 30, 2020July 18, 2015 Trisha Gee

While I was at QCon New York (probably my business conference this year!) I was interviewed by Ralph Winzinger for InfoQ. It felt like a short interview at the time, but we covered a lot of ground – Java 8, Java vs other JVM languages, the effectiveness of the JCP, and the future of Java. … Read more

Java at 20

September 19, 2020May 22, 2015 Trisha Gee

I was asked three simple questions about my thoughts on Java turning 20, and ended up writing a guest post for Voxxed. No wonder I can’t seem to find the time to write these days.

SVQ JUG: The State of Java

September 20, 2020January 29, 2015 Trisha Gee

I think living in a beautiful city in a fantastic climate has its advantages. Not just the obvious ones, but we find people unusually keen to come and visit us on the pretence of presenting at the Sevilla Java User Group (and please, DO come and present at our JUG, we love visitors).

This week we were really lucky, we had Georges Saab and Aurelio Garcia-Ribeyro giving us an update on where Java is now and where it looks like it's going in the future.

Getting Started with MongoDB and Java

November 24, 2020August 14, 2014 Trisha Gee

We've been missing an introduction to using MongoDB from Java for a little while now - there's plenty of information in the documentation, but we were lacking a step-by-step guide to getting started as a Java developer.

I sought to rectify this with a couple of blog posts for the MongoDB official blog: the first, an introduction to using MongoDB from Java, including a non-comprehensive list of some of the libraries you can use; the second, an introductory guide to simple CRUD operations using the Java driver:
