I had the distinct privilege of delivering a keynote presentation at cf.Objective() 2017 in Washington, DC. The slides — probably the most important one is the list of resources at the end — are on GitHub. Thanks to all who did me the honor of listening. I am humbled and grateful.
When I started work this morning, I expected a normal manager day: emails, meetings, shepherding some proposed infrastructure changes through our change management process. That was not to be. What followed instead was most of the day on the edge of my limited Linux troubleshooting abilities, trying to diagnose performance degradation on our production Jenkins server. Around 10:30 AM, Andy messaged me: “Anecdotal Jenkins slowness. Something that regularly takes 3 minutes on my machine takes 18 minutes on Jenkins” This is a story about troubleshooting. Prologue: The environment This story’s main characters are RHEL, Jenkins, New Relic, job-dsl-plugin, and the … Continue reading The Curious Case of the Slow Jenkins Job
Credit Full credit for this idea and post goes to my colleague Andy, who presented this approach at a recent lunch-and-learn at work. A few months after his presentation, I decided to try replicating what he did. This blog post represents what I learned from that effort. Thanks Andy! The Goal For the 3 phones in our house, when one is misplaced, press an Amazon IoT button and have it dial the phone. A single click should call one phone number, double click another, and long click the third number. Then, the phone would ring, and I would listen … Continue reading Going Serverless: using Twilio and AWS Lambda to make phone calls with an AWS IoT button
In the previous post in this series, I covered my favorite development-time helper: running job scripts from the command line. In this post, I’ll cover the differences between job-dsl and Pipelines, and how I currently see the two living together in the Jenkins ecosystem. job-dsl refresher If you’re coming into this post directly, without reading the preceding articles in the series, I strongly encourage you to start at the start and then come back. For the rest of you, a quick refresher: job-dsl is a way of creating Jenkins jobs with code instead of the GUI. Here’s a very simple example: View the code … Continue reading Jenkins-as-code: comparing job-dsl and Pipelines
A while back, I was made well aware of my, shall we say, un-presence. I’d be physically present with my family, but distracted the point of absence. Usually, it was due to a device stealing my time from them. The phone in my pocket was becoming a time-and-attention thief. A Facebook message. A Twitter reply. An email. I am still not great at this — my kids would probably say I’m terrible — but I’ve come a long way and thought I’d share some of my tactics for helping reduce social media and email overload. The point of this is to … Continue reading Remaining more present by controlling information overload
