OPIG Retreat, 2026: Heatwave Edition

Last week, a sizable fraction of OPIG headed to “The Plough” near Bradford on Avon, Wiltshire, for our OPIG Retreat (a.k.a. “OPIGtreat”). Some of us travelled on Monday by train, encountering a biblical deluge, a darkness resembling a train tunnel but filled with pelting rain and bath-tubs of water washing down the train’s windows — and lightning strikes every 30s while changing in Bath Spa…

The red monster storm with black eye is what greeted us as we were arriving in Bath Spa. (Credit: UK Thunderstorm Updates: “This is what the satellite imagery is currently showing from the storm affecting Somerset/ Wiltshire. Cloud tops on this monster have exceeded 40,000ft….”)

Undeterred, and either shuttled by the fabulous Anita from Bradford on Avon station, or walking on foot, we arrived at our lovely destination and home for the week.

Make your code do more, with less

When you wrangle data for a living, you start to wonder why everything takes so darn long. Through five years of introspection, I have come to conclude that two simple factors limit every computational project. One is, of course, your personal productivity. Your time of focused work, minus distractions (and yes, meetings figure here), times your energy and mental acuity. All those things you have little control over, unfortunately. But the second is the productivity of your code and tools. And this, in principle, is a variable that you have full control over.

Even quick calculations, when applied to tens of millions of sequences, can take quite some time!

This is a post about how to increase your productivity, by helping you navigate all those instances when the progress bar does not seem to go fast enough. I want to discuss actionable tools to make your code run faster, and generate more results, with less effort, in less time. Instructions to tinker less and think more, so you can do the science that you truly want to be doing. And, above all, I want to give out advice that is so counter-intuitive that you should absolutely consider following it.

Feeding a drove of hungry OPIGlets

In preparing for battle I have always found that plans are useless, but planning is indispensable.

Following the previous post about OPIG retreat 2022, and having received numerous requests for recipes, I thought I’d document the process of ensuring that 24 people are kept fed and happy. Recipes at the foot of the post.

Disclaimer – these recipes are entirely my own interpretations, adapted where necessary to suit a range of dietary requirements. They are in no way authentic to any national cuisines and are not intended to be.

Disclaimer II: The Disclaiming – all measurements are approximate. I rarely write down recipes or use precise measurements. Taste as you go, and don’t be afraid to add more salt.
