Complex Unique Constraints with PostgreSQL Triggers in Ecto
I recently needed to enforce a database constraint similar in spirit to a unique index, however the criteria for what should be considered “unique” was more complex than what a simple unique index in PostgreSQL would be able to deal with. Knowing that Ecto works by intercepting an error raised by the database, I set out to see if I could implement the complex unique constraint logic in the database and still be able to use the

Rodeo Labs Traildonkey 3.0 - Initial Impressions

The Traildonkey 3.0 from Rodeo Labs is a very capable adventure bike that seems to be begging you to take it outside of its comfort zone. It may not be great at everything, but it is willing to try just about anything once. -
Using the 27" LG UltraFine 5k Display with Linux
I’m happy to report that we did get the monitor working great with Linux after a lot of trial and error (see below for the details about configuring Linux to work with this setup) and all of the other hardware worked well out of the box.

Sky Departure will be Good for Pro Cycling
Whether they find new sponsorship at the end of 2019 or dissolve completely, I think we’ll find that the era of Sky-dominance has drawn to a close.

Race Report: BCCC 2018 Day 1
I’m back for my second year in a row, racing as number 420 in the Baker City Cycling Classic. After dropping out of the race on the last stage in 2017, because I got dropped early on and then ran out of water between feed-1 and feed-2, I’ve spent the last year training like mad, so that I could come back and actually make it to the top of that last climb on that last day.

34 Weeks to BCCC
My goal between now and the end of the year is to maintain a moderate amount of fitness and to get my weight and body-fat percentage within a range that I think will set me up well to hit my ultimate racing-weight goal. Cyclocross is helping to maintain the fitness, but I’m struggling (as usual) with the diet.

MTB Ride from Reehers Camp
Dublin and I went for a mountain-bike ride on the Triple C and Gales Creek trails out of Reehers Camp this weekend, and encountered the most interesting thing I’ve ever seen on a bike ride.

Ride Fuel
Shameless sponsor plug:
One of the benefits of riding/racing with Team Oregon is having access to some pretty sweet deals from our awesome sponsors to help fuel those winter/spring base miles.

Living Intentionally
“Intentional living is the art of making our own choices before others’ choices make us.” ― Richie Norton
I’ve recently been given an opportunity to take some time and think about the next steps in my career and life, which has lead to some deeper thinking about my purpose and how I want to focus the (roughly) second half of my time on this planet.

Saffron and Bourbon Chicken Soup
This relatively easy to make chicken soup with a delightfully complex flavor will probably become my go-to comfort food for treating winter colds. Serve it with homemade, buttermilk biscuits, of course.

Best Chili Recipe Ever
I’ve had a few requests to share this chili recipe from time to time; most likely because everyone who has ever had it subsequently decides it is the best chili they have ever had. Giving credit where it’s due, this is based on Alton Brown’s chili recipe from his book, I’m Just Here for the Food, but modified to my own tastes. The sauce is rich and spicy, although it’s a nice, even keel that doesn’t get hotter and hotter with each bite.

Kookaburra 0.24.0 Released - Exorcised ActiveSupport
I just released version 0.24.0 of Kookaburra to Rubygems.org. While there were no changes to Kookaburra’s API with this release, it is a minor release rather than a patch release, because I removed ActiveSupport from Kookaburra’s dependencies. Previously, Kookaburra depended on ActiveSupport >= 3.0, and this prevented it from working smoothly with Rails 2.x applications (at least in the same Bundler bundle.) Since Kookaburra only used a small fraction of ActiveSupport, it seemed easiest just to break the dependency, so that your application can use whatever version of ActiveSupport it needs.

tmux and the OSX Clipboard
I started using tmux recently after a) I was informed that GNU screen is basically an outdated POS, and b) an excellent book on the subject was published. I’m glad to have made the switch, as tmux is a wonderful improvement over screen. However, on OSX, I found that the

Kookaburra Rewrite for 0.15.1
After getting some good feedback on Kookaburra since the original release announcement as well as using it in a few more projects, Sam and I decided to treat all of the versions prior to 0.15.0 as a spike and rewrite the framework from the ground up. Although we certainly learned a lot about the approach with the pre-0.15 versions, the problems with continuing to grow Kookaburra from that seed became apparent as we tried to use it in more applications.
