Five hundred years ago, Martin Luther nailed a list of grievances to a church door.

I gave a talk to open the 2025 Arrow Summit in Paris, looking back at the history of the Apache Arrow project, some factors that have contributed to its success, and what the past can tell us about how to ensure a bright future.

When my kids were little, we spent lots of time at the playground.

I’m not a morning person, but in the household division of labor, I’m the one responsible for getting the kids up and out to school in the morning.

A rip current is a powerful flow that can drag an unsuspecting swimmer out to sea.

One of the great things about leading a software project is the sense of ownership over what you and your team are creating.

When interviewing developers at Crunch, we sometimes do a live coding exercise using a JavaScript data visualization library.

This week, I wanted to analyze some web traffic patterns back over several years.

At Crunch, we’ve built up our product over the span of six years, and what we’ve built helps a lot of people analyze their data quickly and painlessly.

The 3.2.0 release of httptest is now on CRAN.

In putting up the slides for the talk I gave at last week’s Bay Area R meetup, I figured it would be good to dig up the slides from previous talks and post them here too.

As a product owner and development leader, I often hear that “we have to pay our technical debt” in order to proceed with our product plan.

Recently I analyzed some web traffic for my team at an all-hands meetup.

When you submit a package update to CRAN, they ask you to check some boxes confirming that you’ve done your due diligence on your submission: that it passes its checks.

Publishing a website for your R package is simple with pkgdown.

pkgdown is an incredibly powerful tool for building beautiful websites for R packages.

The 2.3.2 release of httptest has just been published on CRAN.

At Crunch, I occasionally pick up small coding projects to help with project management.

At Crunch, I lead both engineering and product management.

I’m a big advocate of testing and test automation, both on the team I lead and in my own projects.

Over on the Crunch.io dev blog, I wrote about how we used Travis-CI to automate the building of our various static sites.
