Newsletter October 2018

October 09, 2019

Hello Chicago!

October is here and as usual we’ve been busy at CJUG World Headquarters planning exciting things for the Java community in Chicago. Now that Janine is CJUG is President, this probably a good time to let her know that according to our bylaws, she has to dress up as Duke for the meetup closest to Halloween.

Upcoming Events

Venkat Subramaniam
Thursday, November 1

If you’ve never seen Venkat give a talk, you are in for a treat. We are very fortunate to have one of Java’s most popular and sought after speakers come back to preset to CJUG! Venkat presents on a wide variety of subjects and has offered us a choice. We thought it would be great to have YOU, the community, vote on what you want to see!

When you RSVP, take the survey and pick the topic that appeals to you the most:

  • Benefiting from Java 9 Improvements

  • Type Inference: Friend or Foe?

  • Completable Future: The Promises of Java

  • Design Patterns in the Light of Lambda Expressions

  • Java Functional Programming Idioms *Kotlin for Java Programmers

Even if your topic doesn’t end up being selected, it will still be a great presentation. RSVP before this fills up.

Thursday, October 11 at Noon (Online!)

Join Josh Juneau and Bob Paulin where they will go over the general contribution process that many open source projects have. What is a PR? How does branching work? Interacting with an established project. In addition, Bob will cover the Apache Incubation process, and Josh will cover Apache Krazo (MVC).

Office Hours
Monday, October 22 at IBM @5:30pm

Got a project you need help with? New to Java and want some concepts explained, or help sorting out all of your options? Want to just come hang out and code? Come to CJUG Office Hours.

Our optional topic this month is going to be Design Patterns, led by Nick. He will go over some common patterns you are likely to run into, what problems they are good at solving, and how to implement them in Java.

Note this one is starting a bit earlier than usual at 5:30.

Lightning Talks Are Coming

CJUG will be hosting Lightning Talks again in December, so put your thinking caps on and come up with a topic. You don’t have to have any experience with presenting, or professionally created slides, or even do live coding. Get up in front of our friendly CJUG audience and teach us about something you care about, have worked on, or are curious about. You just have to prepare a 5-10 minute talk on anything relating to Java or the JVM and tell us all about it.

This is a great way to begin advancing your career. The ability to stand up in front of a group and teach makes you more attractive to future employers. It’s also the perfect opportunity to see if you enjoy speaking. Several CJUG members who got their start at Lightning Talks regularly present at conferences all around the country.

We’re a friendly audience. We want you to succeed. You can do this.

Java Off Heap

Several members of the CJUG board have a podcast focused on Java news called Java Off Heap, and you can find it in iTunes or

Episode 37: Extra Extra! If you work in Java you gotta take a break from all other news, and listen to this episode! Java is changing its pricing model, and with that comes a lot of new consequences. You can still get it for free, but you gotta know what you’re getting into (Move to OpenJDK!). In another news, Redis is changing is BSD licensing (while usually free, now comes with a ton a caveats for cloud hosts). Lastly, Linus Torvalds (the only one who’s a bigger curmudgeon than Michael Minella) has decided to apologize to those that had to endure his rants! Our industry is changing, and is moving forward!
