A while back, this implementation of a cross-platform sleep for GitHub Actions Runners caught my eye, and I wanted to see what it would take to re-implement sleep from the ground up, while trying to be as cross-platform as possible.

Since I was small, I’d lived my life through screens, one way or another. For the last quarter-century or so, I had been piloting the machine of flesh and sinew to keep my mind going, rarely engaging with the machine itself. This was a mistake.

A common pattern I’ve seen over the years have been folks in engineering leadership positions that are not super comfortable with extracting and interpreting data from stores, be it databases, CSV files in an object store, or even just a spreadsheet. We’re going to cover SQL & DuckDB, then some useful statistical tools: summary stats, distributions, confidence intervals and Bayesian reasoning.

I’ve been managing a fully remote, fully distributed team, covering timezones from UTC-8 through UTC+10, for the last couple of years. Through that time, I’ve learned a lot on organising work, interpersonal relationships, and ultimately how to overcome a lack of promximity to my reports.
