The objective of this study was to investigate the effect of caffeine ingestion on the brain during sleep. In particular, we compared the effects of caffeine to that of placebo on neural oscillations, brain complexity and measures of critical behavior. Importantly, we set out to characterize these effects across REM and NREM sleep, and across age. In a nutshell, we found that caffeine induces a broad boost in brain complexity and a prominent shift towards criticality. These effects were substant

In 1986, an inventor named David Humble rolled out the first self-checkout machine to a Kroger outside of Atlanta. It was a watershed moment for shop owners at the time, who hoped to "increase store profits" and "alleviate labor shortages" — another way to say "avoid hiring workers above the national minimum wage," which was then $3.35 per hour, and just $7.25 today. Fast forward 39 years, and self-checkout has taken the world by storm. Today, there are over 217,000 self-checkout terminals inst

In this post, I demonstrate the optimal workflow for creating new Debian packages in 2025, preserving the upstream git history. The motivation for this is to lower the barrier for sharing improvements to and from upstream, and to improve software provenance and supply-chain security by making it easy to inspect every change at any level using standard git tooling. Key elements of this workflow include: Using a Git fork/clone of the upstream repository as the starting point for creating Debian
