Asyncio: A library with too many sharp corners
A red garden tulip. Photo by my friend Jamie. One of the headliner features of Python 3.4 (released in 2014) was a new library in the standard library: asyncio, provisionally introduced for feedback as an import of the external tulip library. In Python 3.5 (released in 2015), async and await were added as keywords to […]
Personal aviation is about to get interesting (2023)
Aviation is a poster child for economic stagnation. Yes, airline travel has gotten cheaper and saferāgreat. But every other aspect of aviation has struggled or even regressed. As Iāve noted many times, we had supersonic travel across the Atlantic from 1976 to 2003. Today, not even the worldās richest travelers can fly that fast. Another […]
Getting into Flow State with Agentic Coding
I recently found myself in a deep state of flow while coding ā the kind where time melts away and you gain real clarity about the software youāre building. The difference this time: I was using Claude Code primarily. If my recent posts are any indication, Iāve been experimenting a lot with AI coding ā […]
Torqued Accelerator Using Radiation from the Sun (Tars) for Interstellar Payload
Abstract:The concept of exploring space using solar power is energetically appealing, but interstellar solar sails typically require extremely low areal densities (~0.8 g/m^2). This work explores an alternative approach: storing solar energy as rotational kinetic energy, which is later released to propel a microprobe beyond the solar system. The proposed Torqued Accelerator using Radiation from […]

Resizable Structs in Zig
July 26, 2025 In this post I will make the case for the concept of a āruntime resizable structā in Zig. I will then design an API by exploiting Zigās powerful comptime functionality. If you want to skip straight to the implementation, a minimal proof of concept is available as a package on GitHub. Zig […]
