JavaOne 2013: My Presentations

I flew into San Francisco this past Monday to speak at JavaOne 2013, and to meet with my new client. I made sure to wear a Broncos shirt since I was riding the train through Oakland and had some co-workers that were Raiders fans. My trip started off nicely as the Broncos dismantled the Raiders on Monday Night Football. My new team and I watched it during a team dinner at Havana in Walnut Creek. Historically, the Broncos and Raiders have had a heated rivalry historically, so the win was the perfect start to the week.

On Tuesday, I worked from my hotel in the morning, then met James Ward to do some last minute prep for our smackdown. The prior week, we both upgraded our respective apps to use the latest versions of Grails and Play Framework. I ran into a few issues when upgrading, while Play required some API changes.

We both added Memcachier to our apps (to share caching between dynos) and ran some Apache Bench tests. The results showed quite a bit of slowdown compared to last time, which we attributed to caching needing to make network hops. Other than that, we both had to make changes to our framework's buildpacks to get the latest versions running on Heroku, and when we headed for our talk, my instance of Grails wasn't running (60 second boot timeout on startup). The good news is it somehow solved its issues during our talk and was up and running when I checked it after, as it is now. Below is an embedded version of the presentation we delivered.

On Wednesday morning, I tried to attend Venkat's Programming with Lambda Expressions in Java, but quickly discovered it was sold out. My talk on The Modern Java Web Developer started shortly after and I had a fantastic time talking to a packed room and preaching the virtues of learning and staying up-to-date with web technologies. I made sure to include a slide on Avatar, an Oracle-sponsored JavaScript-based framework that requires "very minor JavaScript knowledge". You can view my presentation below or on SlideShare.

According to @JavaOneConf, all JavaOne 2013 presentations will be published on Parleys.com.

After completing my talks, I journeyed to my client and practiced what I preached, successfully finishing a spike that reduced page load time from 8 seconds to 2 seconds. That evening, I attended the Oracle Appreciation Event at Treasure Island, had some cold beer and listened to some loud music.

I had a great time speaking at JavaOne this year, and look forward to my next speaking engagement. In November, I'll be traveling to Devoxx where I'll be giving a 3-hour University session on The Modern Java Web Developer. Hope to see you there!
