10+ YEARS


Over 10 years ago, I wrote my first blog post. Since then, I've authored books, had kids, traveled the world, found Trish and blogged about it all.

Farewell to the 2013-2014 Ski Season

We took things up a notch for this year's ski season: we bought a ski bus (a.k.a. The Syncro) and rented our ski shack out for the season. Our goal was to ski all over Colorado since Abbie had free days at every resort. Personally, I racked up 28 days of skiing, Trish had similar numbers and, Abbie and Jack got between 15 and 20.

Let the VW adventures begin! We picked up the ski bus with a road trip from Sun Valley, ID to Denver. We were hoping to ski at Jackson Hole on the way home. The sub-zero temperatures quickly changed our minds and we learned about its sub-par wind resistance driving through Wyoming.

The kids and I started the season with a trip to A-Basin, followed by a day at Keystone. Then Trish and I hit Mary Jane before heading to Montana for Christmas.

Around this same time, Trish sold her Xterra and we became a one-vehicle family. The Syncro had its first (and only!) breakdown on the way to my parent's on Christmas Eve. We raced Santa Claus to The Cabin, packed in a rented sedan with two kids, two dogs and two cats. We realized afterward the car had bald tires and a broken windshield-washing system. Thank goodness the roads were dry.

The Syncro remained in Bozeman for a week while getting repairs done at Straightaway Motors. We enjoyed the beauty of Montana without it, sledding, skiing at Big Mountain and celebrating New Years with good friends in West Glacier. Taking Trish and the kids skiing in Montana was a ski-life highlight for me. As a teenager, I learned how to downhill ski at Big Mountain and it was really cool to show my family its awesomeness.

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:

Spring Break in Florida: Golf, Beaches and Boats!

Florida is a beautiful state, with sandy beaches, excellent fishing, fun people and a great enthusiasm for golf. When I dreamed up Trish, I knew she'd have an awesome family, but I never expected her parents to have a house on a golf course. Trish's grandma, Claire Stanley, is a legend in her own right. I've never met her, but I knew I loved her when Trish's dad first told me about her "layered shots". When I saw Claire's name listed several times on the walls of the The Country Club of Naples, a deep respect came over me. Claire picked out her house on the 17th hole (Trish's favorite number) of the Country Club in 1966, when the establishment was founded. My bus was born in 1966.

Today, Trish's parents have turned it into a golf and relaxation oasis, complete with beautiful orchid gardens, a sweet pool and Japanese decorations from the country where they first met.

As a golf enthusiast, I'm embarrassed that we've only visited her parents in Naples once before. We bought Abbie and Jack golf clubs last year for Jack's birthday, and they both like to play the game. To make up for our lack of visiting family in Florida, we took our kids on a golf vacation for this year's Spring Break.

10 years ago today, I bought a VW Bus

10 years ago today, I bought a 1966 21-Window Volkswagen Bus. Restoring a VW Bus had been a dream of mine since high school, when I attempted to restore a '69 VW Bug. In October 2005, the restoration project began. Since then, it's been through many shops and had quite a few folks work on it. You can read all about it in When is the bus gonna be done?

Since many long-time readers of this blog are familiar with The Bus Project, it seems fitting to give y'all a detailed update on where things sit today.

This site now powered by Java 8, Tomcat 7 and Wufoo Forms

I recently upgraded this site to use the latest version of Apache Roller. It was a minor release (5.0.3), but I figured I'd document the steps in case "early onset" comes soon. First of all, to download raibledesigns.com and get it running locally, I perform the following steps:

  1. Backup everything using ~/bin/backup.sh on raibledesigns.com
  2. scp backup file to local hard drive and expand
  3. Copy ROOT, skins and repository directories to local webapps
  4. Make sure activation, mail, mysql and jta JARs are in $CATALINA_HOME/lib
  5. Copy roller-custom.properties from raibledesigns.com's $CATALINA_HOME/lib
  6. Copy context files from hosted $CATALINA_HOME/conf/Catalina to local directory
  7. Import database and change roller-custom.properties to match local credentials

Next, to upgrade to the latest Roller release, I do the following:

  1. Download latest Roller release and expand
  2. Copy JARs (from WEB-INF/lib) to existing install (to upgrade dependencies)
  3. Delete any lower-versioned JARS from WEB-INF/lib directory
  4. Copy JSPs (from WEB-INF/jsps) to existing install
  5. Run database migration scripts from WEB-INF/classes/dbscripts
  6. Use a diff tool (like SmartSynchronize) to compare new vs. existing
  7. Test and troubleshoot (if there's startup errors)

This process has worked well for the last 10 years, and it's been in my head the whole time. It's bound to escape someday.

Contact Form Enhancements
In addition to upgrading Roller, I also upgraded Tomcat 6 to Tomcat 7.0.52. In doing so, I found Jakarta's Mailer Taglib doesn't work with Tomcat 7. As you can tell from the aforementioned thread, I've known this for several years. That's the only thing that's stopped me from upgrading Tomcat the past couple years.

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.

Developing an iOS Native App with Ionic

In my current project, I've been helping a client develop a native iOS app for their customers. It's written mostly in Objective-C and talks to a REST API. I talked about how we documented our REST API a couple days ago. We developed a prototype for this application back in December, using AngularJS and Bootstrap. Rather than using PhoneGap, we loaded our app in a UIWebView.

It all seemed to work well until we needed to read an activation code with the device's camera. Since we didn't know how to do OCR in JavaScript, we figured a mostly-native app was the way to go. We hired an outside company to do iOS development in January and they've been developing the app since the beginning of February. In the last couple weeks, we encountered some screens that seemed fitting for HTML5, so we turned back to our AngularJS prototype.

The prototype used Bootstrap heavily, but we quickly learned it didn't look like an iOS 7 app, which is what our UX Designer requested. A co-worker pointed out Ionic, developed by Drifty. It's basically Bootstrap for Native, so the apps you develop look and behave like a mobile application.

What is Ionic?
Free and open source, Ionic offers a library of mobile-optimized HTML, CSS and JS components for building highly interactive apps. Built with Sass and optimized for AngularJS.

I started developing with Ionic a few weeks ago. Using its CSS classes and AngularJS directives, I was able to create several new screens in a matter of days. Most of the time, I was learning new things: how to override its back button behavior (to launch back into the native app), how to configure routes with ui-router, and how to make the $ionicLoading service look native. Now that I know a lot of the basics, I feel like I can really crank out some code.

Tip: I learned how subviews work with ui-router thanks to a YouTube video of Tim Kindberg on Angular UI-Router. However, subviews never fully made sense until I saw Jared Bell's diagram.

To demonstrate how easy it is to use Ionic, I whipped up a quick example application. You can get the source on GitHub at https://github.com/mraible/boot-ionic. The app is a refactored version of Josh Long's x-auth-security that uses Ionic instead of raw AngularJS and Bootstrap. To keep things simple, I did not develop the native app that wraps the HTML.

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.

The Art of AngularJS

Last night, I had the pleasure of speaking at Denver's DeRailed about AngularJS. Fernand (the group's leader) asked me to speak in December, just after I'd finished a European speaking tour. The Modern Java Web Developer talk I created for that tour included a 20-minute AngularJS Deep Dive screencast. I figured it wouldn't be much work to augment the screencast and create an hour long talk, so I agreed.

When I started creating the presentation last week, I decided I didn't want to make the audience watch my screencast as part of the presentation. They could easily do that on their own time. So I wrote, from scratch, a brand new presentation on AngularJS. I tried to include all the things about Angular that I thought were important and useful for me in my learning process. The result is a presentation I'm proud of and enjoyed delivering.

You can click through it below, download it from my presentations page, or view it on SlideShare.

You might notice the presentation has a whole lot of code in it. Normally, when I copy/paste code into a presentation, I use IntelliJ IDEA and everything works. This time, there was something amiss between IDEA 13 and Keynote 6. I tried using IDEA's plugins (namely Copy on steroids and Copy as HTML), but none of them worked. IDEA 12 resulted in the same problem. Then I turned to other solutions. I installed highlight and copied code from the command line. This worked, but the fonts and colors weren't to my liking. Finally, I decided to try another editor: Sublime Text with SublimeHighlight. This worked great and I'm very happy with the results.

Most of my presentations end with a Questions/Contact slide. For this one, I added a few more: people to follow on Twitter, resources to learn from and projects with useful code. Below are a handful of links that greatly enhanced my AngularJS knowledge in the last year.

One of the audience members at DeRailed recommended thinkster.io as a good resource too.

Thanks to Fernand for inviting me to speak and causing me to write this presentation. Creating it greatly improved my AngularJS knowledge and I learned about some new tools in the process. If you'd like to tap into my wealth of knowledge, I'm available for a new gig in April. ;)

Heli Skiing in British Columbia with CMH Gothics

I first learned how to downhill ski in Montana while I was in grade school. A couple times a year, the whole school would go on a field trip to Big Mountain (now Whitefish Mountain). I didn't ski a whole lot in high school, nor in college (at the University of Denver). However, several friends went to DU for the skiing. They'd schedule their classes so they had a couple days off per week, and they'd head for the hills. Two friends in particular, Chris and Chris, were some of the best skiers I'd ever seen. They'd fly through the moguls with legs like rubber bands, upper-body barely moving, legs absorbing the world famous bumps at Mary Jane.

I used to talk about Chris and Chris, long after college, as the amazing skiers with the rubber band legs. I didn't start skiing a lot until I worked for a .com in the late 90s. The VP of Development (whom we now call "The Professor") told us that one of the perks was a "9-inch Rule". The rule was that if it snowed 9", you could take the day off and go skiing, as long as you went to the resort that had the fresh powder. It was crazy how few people took advantage of this, but he and I never missed a day that year. That was likely the first year I'd skied more than 10 days in my life, and I'll bet I skied 20 with him.

I continued to ski a fair bit with my practice wife, then took a couple years off when the kids were born. We got them on skis when they were two years old, and they've been skiing ever since. The funny thing is, I never got really good at skiing until I started taking tips from The Professor. The year was 2010, and I got good enough to be able to ski top-to-bottom bump runs without stopping. Skiing had become a passion for me.

When I met Trish a few months later, I asked her if she skied (hoping to God she did). Her response blew my mind.

"No, I tele."

She went on to explain how she'd started with Alpine, moved to snowboarding for six years and was now addicted to free heeling. I just gazed with a dumb stare and my mouth open.

Last year, Chris M. decided it was high time we did a helicopter ski trip.
