What Do We Owe Our Teams?
Many of my discussions with product leaders (CPOs, VPs and others who manage teams of product folks) are about the substance of product management: portfolios, competing stakeholders, pricing & packaging, tarot cards as a revenue forecasting model.

My Meeting with David Bohm
June 29, 2023. Some scientists seek to clarify reality, others to mystify it. Physicist David Bohm seemed driven by both impulses. He is renowned for promoting a sensible (according to experts like Einstein, John Bell and philosopher Tim Maudlin) interpretation of quantum mechanics. But Bohm also a

Parsing time stamps faster with SIMD instructions
In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string.

Flattening ASTs and other compiler data structures
This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.

Tree-Structured Concurrency
For a while now I've been trying to find a good way to explain what structured concurrency is, and how it applies to Rust. I've come up with zingers such as: "Structured concurrency is structured programming as applied to concurrent control-flow primitives" . But that requires me to start explaining what structured…
