Why I prefer IntelliJ IDEA over Eclipse

Over the last couple months, I've received a few emails asking why I prefer IntelliJ IDEA over Eclipse. They usually go something like this:

I keep seeing you recommending IntelliJ. I keep trying it intermittently with using Eclipse, but I feel like I'm missing something obvious that makes so many people think it's better. Granted having the usual plugins incorporated is nice, but other things like the build process and debugger sometimes seems a step back from Eclipse. Could you please blog a '10 reasons why I love IntelliJ' or point me to something that would clue me in?

I grew to love IntelliJ for a few reasons. It all started in 2006 when I decided to migrate AppFuse from Ant to Maven. Before that, I was a huge Eclipse fan (2002 - 2006). Before Eclipse, I used HomeSite, an HTML Editor to write all my Java code (1999-2002). Eclipse was the first IDE that didn't hog all my system's memory and was pleasant to work with.

The reason I started using IntelliJ in 2006 was because of it's multi-module Maven support. Eclipse's Maven support was terrible, and m2e hasn't gotten a whole lot better in recent years AFAIK.

Back then, I used to think everything should be built and run from the command line. A couple years later, I realized it was better to run tests and debug from an IDE. Now I'm more concerned with the ability to run tests and debug in an IDE than I am from the build system.

In 2009, I started doing a lot more front-end work: writing HTML, CSS and JavaScript. I also started digging into alternate languages for these: Jade, GWT, CoffeeScript, LESS, SASS - even Scala. I found IntelliJ's support, and plugins, to be outstanding for these languages and really enjoyed how it would tell me I had invalid JavaScript, HTML and CSS.

My original passion in software was HTML and JavaScript and I found that hasn't changed in the last 15 years. AFAIK, Eclipse still has terrible web tools support; it excels at Java (and possibly C++ support). Even today, I write most of my HTML code 9 (for InfoQ and this blog) in IntelliJ.

In reality, it probably doesn't matter which IDE you use, as long as you're productive with it. Once you learn one IDE well, the way others do things will likely seem backwards. I'm so familiar with debugging in IntelliJ, that when I tried to use Eclipse's debugger a few weeks ago, it seemed backwards to me. ;)

In a nutshell: the technologies I've worked with have been better embraced by IntelliJ. Has this happened to you? Have certain technologies caused you to use one IDE over another?

How do you stay current with emerging technologies?

I recently received an email from a former co-worker. She was curious to know what I read/do to know what it is "trending" in the software world. I think this is good knowledge to share, and I'm also interested in what others do to keep up. Here's my response to her:

My technique for staying up-to-date is mostly reading, and attending some user group meetings. For reading, I read news.ycombinator.com, as well as infoq.com - who I now write for. DZone.com (esp. Javalobby and its HTML5 Zone) is also pretty good, as is arstechnica.com. I don't read nearly as much as I used to when I was subscribed to all of their RSS feeds and read them religiously.

Nowadays, most of my information comes from Twitter. I follow people that are involved in technologies I'm interested in. I try to keep the number of people I follow to 50 as I don't want to spend too much time reading tweets.

For meetups, most are on meetup.com these days. I'd find a couple that have technologies you're interested in (e.g. a local HTML5 meetup or Java user group) and join the group. You'll get email notifications when they have meetings.

Other than that, sometimes I do "conference driven learning". I'll pick a few technologies I'm interested in learning, submit a talk to a conference or user group, then be forced to learn and present on them when it gets accepted. It can be stressful, but it works and usually results in a good presentation because I can share the experience of learning.

One interesting thing I've realized about Twitter is I can make technologies seem "hot" based on the people I follow. If I'm following a bunch of AngularJS folks, my feed is filled with Angular-related tweets and it seems like the hottest technology ever. If I tweak who I follow to have a bunch of Groovy enthusiasts, or Scala folks, the same thing happens.

Of course, the best way to learn new technologies is to use them in your daily job. I strive to do this with my clients, but it doesn't always work out. I've found that working on open source projects and speaking at conferences can help you learn if you're in a stagnant environment. Then again, if you're not happy at work, quit.

What do you do to stay on top of emerging trends in technology?

First Devoxx4Kids in Denver a Wild Success!

The first Devoxx4Kids Denver was a wild success! This last Saturday, 20 enthusiastic Minecraft hackers gathered at Thrive in Cherry Creek to learn from one of the best. With masterful skill, Scott Davis, founder of ThirstyHead.com, taught everyone how to get a development environment setup, run a local Minecraft server and install plugins into it. You can see the materials we used for this class on Scott's site, at Introduction to Server-side Minecraft Programming.

McGinity Photo was kind enough to snap a bunch of pictures, which you can find on Flickr. A sampling is below:

Devoxx4Kids - Denver Chapter Begins!

Devoxx4Kids I'm happy to announce the first meeting of the Denver Chapter of Devoxx4Kids is now open for registration. It's a two hour class titled Introduction to Server-Side Minecraft Programming and will be taught by Denver's own Scott Davis. The class will be held on May 3rd, from 10am - 12pm at Thrive's Cherry Creek location, where we can comfortably fit 20 students. Cost is $10, but you'll get that back in the form of a t-shirt. Age requirement is 9-18 and kids should have basic computer skills (copy/paste, opening applications, etc.). Minecraft experience will certainly help too.

I'd like to thank Daniel De Luca for his initial assistance with getting Devoxx4Kids setup in Denver and Arun Gupta for starting Devoxx4Kids USA. Arun has been a great help in getting things going and answering my questions over the last few months. Of course, none of it would be happening without Scott Davis or Thrive. If you join us on May 3rd, you'll see that Scott is an awesome teacher and Thrive has some incredible facilities.

My initial goal with Devoxx4Kids in Denver is to host a class or two this year. If there's enough demand, we can expand. For now, we're starting small and seeing where it takes us. If you're interested in teaching a future class, please let me know. We'd love to teach the kids a number of skills, from Scratch to NAO Humanoid Robot programming to building things with Arduino and Raspberry Pi.

Documenting your Spring API with Swagger

Over the last several months, I've been developing a REST API using Spring Boot. My client hired an outside company to develop a native iOS app, and my development team was responsible for developing its API. Our main task involved integrating with Epic, a popular software system used in Health care. We also developed a Crowd-backed authentication system, based loosely on Philip Sorst's Angular REST Security.

To document our API, we used Spring MVC integration for Swagger (a.k.a. swagger-springmvc). I briefly looked into swagger4spring-web, but gave up quickly when it didn't recognize Spring's @RestController. We started with swagger-springmvc 0.6.5 and found it fairly easy to integrate. Unfortunately, it didn't allow us to annotate our model objects and tell clients which fields were required. We were quite pleased when a new version (0.8.2) was released that supports Swagger 1.3 and its @ApiModelProperty.

What is Swagger?
The goal of Swagger is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.

To demonstrate how Swagger works, I integrated it into Josh Long's x-auth-security project. If you have a Boot-powered project, you should be able to use the same steps.

Comparing JVM Web Frameworks at vJUG

A couple months ago, I was invited to speak at Virtual JUG - an online-only Java User Group organized by the ZeroTurnaround folks. They chose my Comparing JVM Web Frameworks presentation and we agreed I'd speak yesterday morning. They used a combination of Google Hangouts, live streaming on YouTube and IRC to facilitate the meeting. It all went pretty smoothly and produced a comfortable speaking environment. To practice for vJUG, I delivered the same talk on Tuesday night at the Denver Open Source Users Group.

The last time I delivered this talk was at Devoxx France in March 2013. I didn't change any of the format this time, keeping with referencing the Paradox of Choice and encouraging people to define constraints to help them make their decision. I did add a few new slides regarding RebelLabs' Curious Coder’s Java Web Frameworks Comparison: Spring MVC, Grails, Vaadin, GWT, Wicket, Play, Struts and JSF and The 2014 Decision Maker’s Guide to Java Web Frameworks.

I also updated all the pretty graphs (which may or may not have any significance) with the latest stats from Dice.com, LinkedIn, StackOverflow and respective mailing lists. Significant changes I found compared to one year ago:

JavaOne 2013: Videos of Presentations on Parleys

Duke Rocking Out This year marked my first time speaking at JavaOne. It seems to have gone well, especially since audience feedback resulted in a JavaOne Rock Star Award. I'm very humbled to be listed with some really great speakers. Congratulations to all the other Rock Stars - as well as everyone that had the courage to submit and present a talk this year!

For the top sessions at JavaOne 2013, Oracle worked with Parleys to capture the audio and synch it with the presentations. They published them in a JavaOne 2013 Channel and my presentations were included. Without further ado, here they are for your viewing pleasure.



If you happen to watch these and have any feedback, please leave a comment or send a tweet to @mraible.

A Webapp Makeover with Spring 4 and Spring Boot

A typical Maven and Spring web application has a fair amount of XML and verbosity to it. Add in Jersey and Spring Security and you can have hundreds of lines of XML before you even start to write your Java code. As part of a recent project, I was tasked with upgrading a webapp like this to use Spring 4 and Spring Boot. I also figured I'd try to minimize the XML.

This is my story on how I upgraded to Spring 4, Jersey 2, Java 8 and Spring Boot 0.5.0 M6.

When I started, the app was using Spring 3.2.5, Spring Security 3.1.4 and Jersey 1.18. The pom.xml had four Jersey dependencies, three Spring dependencies and three Spring Security dependencies, along with a number of exclusions for "jersey-spring".

Upgrading to Spring 4
Upgrading to Spring 4 was easy, I changed the version property to 4.0.0.RC2 and added the new Spring bill of materials to my pom.xml. I also add the Spring milestone repo since Spring 4 won't be released to Maven central until tomorrow.

Devoxx 2013 + a Nordic Countries Speaking Tour

Trish at Pelgrom Two weeks ago, Trish and I boarded a flight for one of our favorite conferences: Devoxx. After a brief layover in Frankfurt, we arrived in Amsterdam and took a train to Antwerp. Within hours, we'd settled into our hotel near the center of Antwerp and strolled over to the dungeonous, yet cozy, Pelgrom restaurant. We were hoping for a delicious dinner, but found much more. We ran into James Ward, Dick Wall and a number of other enthusiastic speakers from the conference. Since I had to speak the next day, we didn't stay long, but we did share a number of laughs with some great people.

Tuesday (November 12), was a University Day at Devoxx, and I had my talk that afternoon. I spent a couple hours finishing up my talk that morning, then grabbed a taxi to head to the conference. I was honored with the opportunity to speak in Room 8, which is a huge theater that holds several hundred people.

Devoxx: A Speaker's Perspective The Modern JVM Web Developer AngularJS Deep Dive

I presented a lengthened version of The Modern Java Web Developer presentation I did early this year (at Denver's JUG and JavaOne). Based on your feedback, I chose to do deep dives on AngularJS, Bootstrap and Page Speed. I've always enjoyed speaking at Devoxx because attendees are so enthusiastic and passionate about the conference. I received an immense amount of feedback, both in praises and criticisms. The critics indicated there were too many buzzwords and not enough substance. Others complained that the AngularJS Lipsync that I did was too deep.

I made sure to review and process everyone's comments, and then used them to improve the presentation throughout the following week. I learned to elaborate on the fact that many of the technologies were important to know about, but not important to know through-and-through. I made sure to mention that the use of CoffeeScript and LESS is often limited (or embraced) by team members and their willingness to try new things. If you're not writing thousands of lines of JavaScript or CSS, it probably doesn't make sense to use these languages. Furthermore, if your team members are struggling to write JavaScript or CSS, introducing a new language is probably not the best thing. I also reminded people to be skeptical of new technology, but also to be open-minded and give everything a chance. The 10-minute, download-and-try test, is a great way to do that.

You can find my presentation below, download it from my presentations page, or view it on SlideShare.

Within this presentation, there are links to each of the deep dives. The last two are screencasts that I added audio to a few days ago.
