2022 September Meeting - We're Back!

September 13, 2022 - 11:30am

After a too-long absence, the Oklahoma City Java Users Group is making a comeback! It’s going to take us a bit to get completely back up to speed, but we’re going to get started then tighten things up as go. That means, for least this month, we’ll be meeting in a conference room at Starspace (as opposed to the event space used to), at least for now, and no food, so you’ll need to bring your own. We’re working on fixing those logistics, but, as I noted, we̵... Read More

[Re-]Kick-off Meeting

Good afternoon, Oklahoma City. It’s been a while since the OKC JUG has met, and we’re trying to fix that. The details are still being working out, but that’s where you come in. As has been the case throughout the history of the JUG, your opinion is desired, and we have an opportunity for you to share it. We, the Steering Committee, will be meeting Wednesday, August 3 at 11:30 at McAlister’s Deli on NW Expressway. We’re going to work through topics like when to... Read More

Stay tuned...

It’s been a while since you’re heard from us, and for that we’re sorry. There have been a number of circumstances, not the least of which being COVID, that has knocked us off our game. We are currently working diligently to restart the JUG and, hopefully, return to being a fun and helpful part of your work day. :) Read More

2019 April Meeting

April 09, 2019 - 11:30am

The phrase Denotational Semantics is an academic term for mapping programs to mathematical objects as a way to define their meanings. This phrase is not well-known in industry but we use it here to make it clear that this presentation is a shamelss rip off of a talk by Erik Meijer of a similar title. Erik Meijer, the founder of Applied Duality, is often cited as the inventor of 'reactive', a group of frameworks which have shown up in almost every programming language. The universal applicabi...

2019 March Meeting

March 12, 2019 - 11:30am

As microservices have exploded on to the scene, so have microservice frameworks. In the JVM world, we have a myriad of options. In an already crowded space, though, a new framework has appeared that is extremely promising. Micronaut is a polyglot microservice framework from the inventors of the Grails framework, supporting Java, Kotlin, and Groovy out of the box. Micronaut ships with support for a wide number of capabilities, including dependency injection, aspect oriented programming, objec... Read More

2019 February Meeting

February 12, 2019 - 11:30am

Every developer creating real-world applications will have to eventually troubleshoot code performance issues - sometimes even in Production systems. In this session we will show a couple of essential tools that every Java developer should know about and can use to gather detail performance metrics (CPU, Memory, Threads, Hot Methods, etc.). With the help of these tools you can get to the bottom of tough issues such as bottlenecks caused by locking and memory leaks. We will specifically cover... Read More

2019 January Meeting

January 08, 2019 - 11:30am

In this session we will showcase the main features of Project Lombok (https://projectlombok.org) and demonstrate how you can make your Java code cleaner, more readable, and way less verbose. With the information shared in this talk you should be able to start using Lombok right away in your Java projects - even legacy projects. Speaker Bio Bryce Easly is a Senior Full Stack Developer who loves technology and has been developing web applications for almost a decade. He’s built compl... Read More

2018 December Meeting

December 11, 2018 - 11:30am

We will start by introducing the concept of reactive programming and how it can benefit, simplify, and streamline software development and deployment. Then we will dig into the Reactor implementation of this idea, and finally we will run some code to show reactive at work. Speaker Bio Andres Barbaro is Vice President of Software Development at Power Costs, Inc. (PCI); Responsible for managing the software development and engineering practice across the entire organization and product port... Read More

2018 September Meeting

September 11, 2018 - 11:30am

At the end of this month, Oracle is scheduled to release Java 11. In this session, we’ll see what’s new in the latest revision of the world’s most popular programming language. We’ll start with a rundown of features, including those added in Java 10 to get us to date, and end with examples of Java 11’s additions. IMPORTANT NOTE: Due to a scheduling conflict at StarSpace46, we will be meeting this month at Clevyr. Many thanks to Aaron Krauss for the hospitality! ... Read More
