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.

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">
    <name>TagsIndex</name>
    <description>Tag index page</description>
        <link></link>
    <navbar>false</navbar>
    <hidden>true</hidden>
    <templateLanguage>velocity</templateLanguage>
    <contentType>text/html</contentType>
    <contentsFile>Weblog.vm</contentsFile>
</template>

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 Overstock.com 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. :)
