This year will be EPIC for JAVA

So we started the year rolling with Big names (Jeff Genender and Matt Konda), and is JUST GONNA GET BETTER, I can’t tell you how excited we are at the CJUG to bring you great presentations, great events, and great networking overall. We have grown so much in the past year, and we are still expecting grow.


By the numbers (We are 735 CJUGers, let’s break the thousands barrier)

We set a goal of getting 810 members by the end of 2013. AND WE GOT PRETTY CLOSE. We are now a vibrant community of 700+ People, and boy, it just makes me feel proud. We are becoming the larger more active Java User Group in the United States, and we are not going to rest until we are the LARGEST U.S. Community :) . So by the end of the year, let’s make CJUG have more than 3,000 members. I know we are all there. Get EVERYONE you know to join in and participate. Tell them about our group, tell them how cool it was last year, and tell them that 2014 is going to be even larger, better, and with the release of Java 8, it’s going to be EPIC.

Speaking of EPIC

Java 8 is around the corner, and we are gearing tons of presentations on what it brings. It is the release we all have been salivating about (lambdas, lambdas, lambdas). We will get all kinds of talks, including JavaFX, JavaEE, and everything Java 8 touches. So stay tuned to our new events.

You gotta come and join us this Feb 6 (Gradle and 3-tier pattern) (­…­/)

Ok, so we have not one, but TWO Chicagoland Celebrities coming out this Thursday. Bob Paulin (yeah, the Bob Paulin that helps get things organized, and have that awesome presentation on getting the right technology ‘mix’) is gonna talk about Gradle and Continuous delivery. Not just that, following up after him we have Brett Lindsey talking about developing interfaces for 3-tier architectures. Brett, who, in another life was like a computer science professor and have the ability to explain, entertain and engage on his presentations (He presented on Spring Planting). It’s such a DOUBLE FEATURE, that you should NOT miss. People will pay real hard-earned cash to hear what they want to say, but, they are selfless and want YOU to have all the knowledge, so come-on, show up at Loyola’s and let the knowledge transfer begin!


Ah, new year, new officers, same old dedication to the Organization

So we had officer nominations in the past week, and just for everyone to know, the CJUG have officially appointed:

Bob Paulin as Community Leader ( 

Yay! He will make sure the community becomes just ‘AWESOMER’, and is in charge of making sure we are the Biggest, Baddest, Awesomest Java User Group out there.


Michael Minella as Meeting Director (

And event Director, would there be a Conference in the future? mayyyybe.. And you can bet Michael will make sure it’s epic, from our regular meetings to the big events. He already promised to have a even bigger and better meeting roster than last year

Monica Gee as our CFO (

Ah, money matters, and there is nothing more certain than Death and Taxes. She is helping us getting all our finances organized. We are growing, and we want to plan bigger things, so we need someone who knows Money :)

Cedric Hurst as our Sponsorship Director (

Cedric is helping sure that “Free” for CJUG members stays Free by going out and finding places, spots, dropped pennies, he is making sure that we always have a viable group. Hey! Do you have a space for us to host an event? Would you like to treat us beer and pizza? Are you interested in an bronze,silver, gold level sponsorship? Cedric is your Sponsorship Ninja-Rockstar-Guru (just try to picture that, it’s almost impossible)!

So, drop them a line and say “Hi” and Congrats. Give them a couple of words of encouragement. They are really selfless and are just doing it because we love the language, we love the community, and more specially we really believe Chicago is the best place to be a Developer (specially in Spring, I have to say that these Polar Vortexes were kinda tough :) ). But a last, programming is not for the weak of heart

Happenings for November 4th, 2013

Oh we are going full EE THIS THURSDAY!

We have two great 30 min sessions for Thursday. The first one is famous author,  Josh Juneau (I actually worked with him co-writing the Java 7 Recipes book, and he is phenomenal. He knows his stuff and is always curious about what’s new and upcoming. He elbows with the likes of Arun Gupta and Peter Pilgrim which are big pillars in the Java EE Community!

And for those of us who remember the old movie theaters, this is a DOUBLE FEATURE, on which John Freeman will be talking about WebSockets. The official JavaEE “Hammer” for the many problem nails! He’ll cover what are WebSockets, best practices and integration with Spring 4. Even if you knew about WebSockets, this presentation still worth coming for! Sign-up now!


Tut-tut we are at 600 and is November :P (800!)

Keep spreading the word and getting people to sign-up! We have our stretch goals, and we want to get to 800 by the end of the year. We can still do it! Let everyone you know sign-up and tell them we are here to help.

SOOO, you couldn’t go to JavaOne? Don’t despair, the Sessions are now ONLINE

Go and click on the link, and get bombarded by so much awesomeness you will go blind! (Previous sentence must be read on Jeff Black’s Kung Fu Panda voice, go ahead, try again J).  But seriously, the first batch of content is coming out, and you will have the opportunity to listen to all the world-class sessions from the comfort of your home (or work).

Have a question? Send an e-mail to

We are letting our mentors be online. Got a question that you want help on? Can’t find your answer in the internet? Never despair, just send an e-mail to and we will make sure one of our cool and hip mentors reply and let you keep developing!

Sshhhh, we are planning an event for this December (it’s a secret!)

We are thinking of having a get-together and plain just talk fun for December, details are going to come soon! Usually December is hard to get speakers scheduled for both tracks, so we might just have one speaker event in December, and then a plain-old, let’s get together and be merry! Have any ideas? Drop me a line


Hey Awesome CJUG Dude/Dudette, wanna give us a hand?

Looking for volunteers to help us organize regular events, networking evens, hack-a-thons, job fairs, and lastly a conference. Wanna participate? Have any time for us? Wanna help make Chicago the BEST place for being a Java developer? Send me an e-mail and let’s talk!

Happenings for Oct 15, 2013

Uncompressing from J1

Oh dear, JavaOne was bigger and greater than ever. There were tons to learn, tons to talk, and your JUG represented Chicago with the other user group Leaders. We are excited of the things that other JUGs are doing (including newsletters and tips for getting more presenters), and they were “impressed” by the awesome community we have here in Chi-town. From the Americas we are growing as one of the larger JUGs (with 567 members, we are definitively “not Small”).

BUT!. (there is always a but)

We are not the Largest User group yet. London Boast 3500 members and SouJava (Brazil), more than 5k (some say is on the 10k). So let’s not get lazy and keep driving our membership! Thanks to our previous growth we have been able to secure great speakers (including Venkat , Reza, Uncle Bob). AND we have already secured Arun Gupta (coming in 2014), and more to talk about Java EE. (See minute 8:50, here WE CAN DO THIS


Wanna keep seeing high-caliber speakers. It’s easy! Just keep telling your peers (and nag them) to become part of our user group. We are always free, we usually have pizza, and we always have a good time with friends, and familiar faces :D .


WE ARE FAMOUS! (JavaOne Interview)

We got featured in the JavaOne Magazine (, page 10, and look at you! at the time of the interview we were a measly 360 members. Ah, but we won’t stop until we are the largest U.S. (and then the World! muahahahah <- Insert Dr. Evil laugh ) User group :)


So Tuesday is huuuuuge!

We have two events going on that day. At CME around lunchtime we have Jack Shirazi. He elbows with the big names in Java performance, and he wrote a classic on Java Performance Tuning! so get a brown bag lunch, and go see him!

AND then we have Uncle Bob coming to talk about Clojure! We are full for this event, so I do have a favor to ask. If you think you cannot come, let someone have a chance. We are doing this in coordination with the ACM and Loyola, and is great collaborating with them. As we keep doing these events we will start bringing new collaboration opportunities for all of our groups together, to be even bigger, and better.


Ada Lovelace Day (Tuesday Oct 15th).

This day of celebration is about sharing stories of women — engineers, scientists, technologists or mathematicians — who have inspired you to become who you are today. The aim is to create new role models for girls and women by raising the profile of other women in STEM.  If you would like to celebrate the achievements of women in science, technology, engineering and math, consider writing a blog or tweeting about a woman in STEM who inspires you, and include #ALD13. (Thanks Tori Wieldt for letting us know!)


Btw, let’s make the future Java 

This is the opening for the JavaOne Keynote (

And the most inspiring part of the Community Keynote at 19:40…

If you want to help organize Devoxx for Kids here in Chicago, or thinking of doing outreach programs contact me, and we’ll make it happen


Sofware Craftmanship Conference (November 8-9)

There is the Sofware Craftmanship conference coming soon (November 8-9, 2013). And it’s so close (AON center), over two days (Fri-sat),at @ $440. still waay cheaper than J1.AND, if you register, there is a question about “if someone recommended this event to you?”. Say yes, and put down CJUG ;) .

From their FAQ: “SCNA welcomes any current or aspiring software developers, entrepreneurs, small business owners, development managers, and technology professionals interested in improving their craft, their community, and themselves. We’d love to have you, no matter how broad your interests and experiences.”


Chicago Startup Weekend Mobile (October 18th – 20th), @ 30% off

Our evil brothers at the .net user group (kidding, Andy is pretty cool actually, and he’s been helping with this conference) let us know of this conference happening THIS WEEK. Don’t waste time! Get registered!

From their site “Startup Weekend returns to Chicago October 18-20th with its first mobile themed event!  We’ll be hosting 100 of Chicago’s best and brightest mobile entrepreneurs, along with coaches and sponsors to help turn their ideas into validated products over the course of 54-hours!

Frontend “vs” Backend – Getting the Right Mix

Thank you Chicago Java Community for a great turnout. I hope you enjoyed the presentation. Here is the code:

And for those who missed it. Here is the recording:

Modern website architectures are typically composed of 2 parts: frontend and backend. Building out frontend and backend components requires diverse skill sets and often have competing interests when it comes to developer productivity and site performance. This talk will discuss some ways Java frameworks deal with these issues as well as benefits and tradeoffs. The talk will include combine demos with cutting edge frontend frameworks (Handlebarsjs, CoffeeScript, Less) and popular Java backends (Spring, Apache CXF).

Bob Paulin is an independent consultant that has been developing on Java for the past 10 years. Bob is focuses on Business Enablement and Web Centric Applications. He’s presented in the past at CJUG on Apache Sling and is currently helping his clients perform modular development/design, automation for continuous delivery, and build forward leaning web applications. When not coding, Bob enjoys coaching football and spending time with his with his wife and 3 kids.

Happenings for May 10, 2013

I’ve got the Power! (The Power of Gradle, that is)

Join us on Tuesday, May 21st to hear what Gradle is all about, with real world examples! Tim O’Brien of Gradleware fame will be there (and he might even have a prize or two!). Also we will be donning a new location, 300 West Adams, just in front of the Willis (it’s so hard, it will always be Sears) Tower. Check the map and details in our Meetup page, and attend

We got 210 CJUG members in Meetup, (the .NET user group has 330).

Come on, I know there are much more Java developers, CJUG Needs you! Spread the word, forward this email to your developer’s distribution list. Shout “CJUG is Awesome” from the top of your cubicle (or office), mention it casually at cocktail parties (“hey, I’m member of the Chicago Java Users Group, they are a fancy bunch”), add it to your email signature (“CJUG Member”), share with students, professors, your local barista. Let everyone know (and sign) to our Meetup group at

Come and let’s do some Spring Planting this June 6th

Our trusted Brett Lindsley will take us through the process of creating a web application from the ground-up. Even if you have done a web app before you might’ve not seen all the interactions that happen when building one. Join us on June 6th! (Venue tbd)

Red Hat Developer Exchange, JBoss User Developer Conference (JUDCon) and CamelOne at Boston (June 9th ~ 11th)

If you are around Boston on June 9th to the 11th you can attend these conferences at a 99$ discounted rate (Just for being a fancy CJUG member), just use PRECONJUG registration code and voila!




The Cravin’ Maven video is online

If you couldn’t make it to our Cravin’ Maven presentation (an Intro to Maven) by Brett Lindsley, you can find the video (and all the others) at

What’s the Chicago Java Users Group up to?

A little update for you on what are we doing. We have organized our finances and have put in place a solid sponsorship program (Thanks Scott and Michelle!), we are furiously upping the number of presentations per-month and finding new locales to present (thanks Brett!), have created a mentorship program which is awesome and btw, you should really use them (Thanks Mike and Bob!), and are actively trying to reach out and help the actual Chicago Community through initiatives like Random Hacks of Kindness (, thanks Rishu!). We have even reached across the aisle to the .Net User group  (and Scala, and JBoss, and Web Development) to organize co-sponsored events.


In all we’ve been busy. There is no monetary compensation for anyone working at the CJUG, so if you happen to see any of them, give them a big hug (or a slap on their back), and tell them “Thank you!”


But with everything else, we need you. Yes, you. I want to drive our membership up, discover all Java developers in the Chicago Area, and create a strong, solid and vibrant community of Java developers that can learn, grow and make a difference.  To accomplish these goals I need every Java professional and Student to know, sign-up and participate in our group. Are you a recruiter? Well, tell your candidates about the organization. It’s like sending them to a free conference to learn new stuff and they will only get better. Are you a student? Tell your classmates, participate, create and volunteer (this will help you even on your resume). Are you a teacher? Contact me and we can do projects for your student body on which we teach them what is required from the corporate world in terms of projects. Are you a developer? By all means, share and join us. You are the soul and the reason volunteers flip over backwards to get things moving and created. Help me out by getting more people signed-up and participating in our JUG.

Peace out! (wasn’t that out of fashion after the 90s ?)
