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.

Be careful when switching MySQL to UTF-8

Earlier this week, I noticed a couple strange issues on this blog and sent an email to the roller-user mailing list. I figured both issues were caused by my upgrade to Roller 5. Basically, my tag cloud wasn't working and I noticed a bunch of blog entries that had truncated data. I'd provide links to the truncated posts, but I believe I've fixed them, so links would be useless. This post is to make others aware of something I wasn't: be careful when switching MySQL to UTF-8.

The first issue, 404s from my tag cloud links, was something my theme was missing. It seems the tagIndex action is new in Roller 5 and required for tag clouds to work. To fix this issue, I had to add the following XML to my theme's theme.xml file.

<template action="tagsIndex">
    <description>Tag index page</description>

Since I wanted to replicate Roller 4's behavior, pointing the contentsFile to Weblog.vm worked just fine. The nice thing is I can always change it to another page and customize it to show more information about the selected tag.

The 2nd issue, data truncation, was a bit trickier. I thought it might've been something Roller did when upgrading my database from Roller 4 to 5. I didn't suspect upgrading from MySQL 3 to 5 would cause it. From my previous upgrade post:

At this point, I figured my database might be slightly hosed, but since it was simply creating tables, I was probably OK. I restarted Tomcat and left the old version in place while I waited for a MySQL 5 database instance from my hosting provider, KGB Internet. Once I got the new instance, I imported my backed-up database, ran the upgrade script and everything worked just peachy.

Keith at KGB looked into my issue and thought the problem was the charset. My old MySQL 3.x database used latin1 while my MySQL 5.x database uses UTF-8. The symptom looked familiar:

Be careful when switching to UTF-8. Once you have converted your data, any program/webapp that uses the database will have to check that the data they are sending to the database is valid UTF-8. If it isn't then MySQL will silently truncate the data after the invalid part, which can cause all sorts of problems.

Luckily, I had a backup of my pre-upgrade database and was able to convert and recover everything successfully with a little iconv, perl and numerous mysqldump and mysql import commands. Of course, it's possible there's still some jacked entries and comments. If you noticed any truncation, please let me know and I'll get them fixed.

Farewell to the 2010-2011 Ski Season

I'd call the 2010-2011 the best ski season ever, but it's really just the best ski season so far. In 2008, I wrote about a great 21-day season. This time last year, I wrote about an amazing 25-day season. This year, I took it up a notch and aimed for 30 days. I'm proud to say I accomplished my goal and had an awesome time doing it. I skied with more people I'd never skied with before (largely in part to my cool co-workers from Overstock) and shared many days with the lovely Trish McGinity.

The season started with a trip to Copper, shortly after Abbie's 8th Birthday. I remember that day clearly as the kids were a bit rusty and had a heckuva time on their first run. Sobbing, whining and fear surrounded them the entire time. After the first run, I had some hot chocolate with them, calmed them down and then proceeded to the bunny slope for some turns. The lift was broken when we got there so we had to hike for a few runs. Amazingly, Abbie said it was the most fun she'd ever had skiing, which surprised me after her meltdown on the first run.

It's fun to compare that day to the last day I took them this season. We did the same run (a blue at Copper) and both kids were doing parallel turns and having a blast. Actually, Jack was the only one doing parallel turns, Abbie was flying down the mountain, not turning at all. She was going so fast her legs looked like rubber bands, weaving and bobbing over the bumps in the snow. I'm awful proud of my little skiers.

As for me, I happened to land a new gig in Utah, home of the greatest snow on Earth. My interview with was two days, with the 2nd day on the slopes at Snowbird. It was easily the best interview I've ever had.

That week, I returned to Denver for 3 days of skiing Breckenridge and A-Basin for Trish's Birthday Weekend. After returning from Christmas in Florida, I got a couple days in at Mary Jane and then accomplished 10 days before 2011 while skiing in sub-zero temperatures at Steamboat for New Years.

The next 4 months of skiing were fantastic with many firsts. I experienced Alta, Crested Butte and thigh-deep powder for the first time.

We finished up the season with a hut trip after TSSJS in Vegas, a weekend with the kids at Copper (as mentioned above) and Spring Splash at Winter Park.

For next year, I think I'll keep my goal at 30 days. If everything works out as planned, we'll have a place in the mountains this fall and it'll be a bit easier to hit the slopes without sitting in traffic. For now, I'm pumped about the beginning of mountain bike season. I took Trish and I's Gary Fisher Hi-Fi Plus's to the shop for tune-ups yesterday and we have a trip planned to Moab for Memorial Day. It's gonna be a great summer. :)

Two Opening Days with a Stopover in Kraków

Opening Day is a special event in Denver. The night before, it feels like the whole city is alive in anticipation of the big event. On Opening Day, it's typically a gorgeous spring day and serves as a great kickoff to baseball season. This year, we decided to take things up a notch and hit two opening days instead of one. The dates just happened to line up so we could go to the Rockies Home Opener on April 1st, fly to Kraków for the 33rd Degree Conference and make it back to Boston for the Red Sox Home Opener. Since Trish's brother lives near Boston, and I have good friends there, it sounded like the perfect vacation. To make a crazy vacation schedule even crazier, Trish and I moved in together the day before it all started. With moving and trying to finish my basement sauna before we left, we've definitely had a hectic few weeks.

Nightmare with water? Yeah, Trish'll do that to ya! Sarah and Joe Rockies Opener! Cargo!

After attending the Rockies Home Opener and having a great time with friends, we got to bed early and woke up on Saturday for our flight to Kraków. It was a 2 o'clock flight, so we got lots of sleep and then proceeded to thoroughly enjoy our flight when we upgraded to Business Class from Chicago to Munich. Business Class is the way to travel internationally. We arrived just after noon on Sunday and spent the afternoon exploring Kraków's Old Town and trying to stay awake. The weather was beautiful and it seemed like it might've been the warmest day of the year.

On Monday, we spent more time in the center of Kraków, wandering through the Main Market Square, Wawel Castle and the very cool Dragon's Den. We had lunch outside, again enjoying the great weather and some local beers. We were surprised to find that kamikaze shots are served in groups of four, rather than just one like it's done in the US. That evening, we enjoyed an excellent Italian dinner at Aqua e Wino.

On Tuesday, we headed to Aushwitz. This was a very sobering experience, but I'm glad we did it. It made me wonder if this type of thing could happen again, only to realize that it has. That evening, we sipped on martinis at the Metropolitan.

On Wednesday, I delivered my talk on Comparing JVM Web Frameworks. You can download the PDF or view the presentation on Slideshare if you're interested. The conference itself had a spectacular schedule and speaker lineup, so I was a little disappointed I didn't attend any sessions. We did make it to the ZeroTurnaround Party that night and had a lot of fun talking to Grzegorz, Martijn and Anton.

We woke up Thursday and headed to the airport for our flight back to the US. We landed in Boston at 6:30 pm and headed to my friend Chris's house in Concord. You might remember Chris from my first game at Fenway Park. Friday, we joined other friends, hopped on the train and headed to Yawkey Way for a beer before the game. Our seats were in the bleachers, but we had a fantastic time watching the Red Sox win their first game of the year.

Fenway Paak! Morse and Kidder Happy Siblings Erika and Julie Red Sox Win!

We went to another game on Saturday with Trish's brother and a friend of his. We then proceeded to spend a relaxing Lazy Sunday with his family before flying back Monday morning.

Thanks to all our friends who participated in the opening day festivities as well as to Grzegorz Duda for inviting me to speak at 33rd Degree. We had a blast!

AppFuse 2.1 Released!

The AppFuse Team is pleased to announce the release of AppFuse 2.1. This release includes upgrades to all dependencies to bring them up-to-date with their latest releases. Most notable are JPA 2, JSF 2, Tapestry 5 and Spring 3. In addition, we've migrated from XFire to CXF and enabled REST for web services. There's even a new appfuse-ws archetype that leverages Enunciate to generate web service endpoints, documentation and downloadable clients. This release fixes many issues with archetypes, improving startup time and allowing jetty:run to be used for quick turnaround while developing. For more details on specific changes see the release notes.

What is AppFuse?
AppFuse is an open source project and application that uses open source frameworks to help you develop Web applications with Java quickly and efficiently. It was originally developed to eliminate the ramp-up time when building new web applications. At its core, AppFuse is a project skeleton, similar to the one that's created by your IDE when you click through a wizard to create a new web project. If you use JRebel with IntelliJ, you can achieve zero-turnaround in your project and develop features without restarting the server.

Release Details
Archetypes now include all the source for the web modules so using jetty:run and your IDE will work much smoother now. The backend is still embedded in JARs, enabling you to choose with persistence framework (Hibernate, iBATIS or JPA) you'd like to use. If you want to modify the source for that, add the core classes to your project or run "appfuse:full-source".

AppFuse comes in a number of different flavors. It offers "light", "basic" and "modular" and archetypes. Light archetypes use an embedded H2 database and contain a simple CRUD example. Light archetypes allow code generation and full-source features, but do not currently support Stripes or Wicket. Basic archetypes have web services using CXF, authentication from Spring Security and features including signup, login, file upload and CSS theming. Modular archetypes are similar to basic archetypes, except they have multiple modules which allows you to separate your services from your web project.

AppFuse provides archetypes for JSF, Spring MVC, Struts 2 and Tapestry 5. The light archetypes are available for these frameworks, as well as for Spring MVC + FreeMarker, Stripes and Wicket. You can see demos of these archetypes at

For information on creating a new project, please see the QuickStart Guide.

If you have questions about AppFuse, please read the FAQ or join the user mailing list. If you find any issues, please report them on the mailing list or create an issue in JIRA.

Thanks to everyone for their help contributing patches, writing documentation and participating on the mailing lists.

We greatly appreciate the help from our sponsors, particularly Atlassian, Contegix and JetBrains. Atlassian and Contegix are especially awesome: Atlassian has donated licenses to all its products and Contegix has donated an entire server to the AppFuse project.
