Operationalizing Macaroons (fly.io)
We’re Fly.io, a security bearer token company with a public cloud problem. You can read more about what our platform does (Docker container goes in, virtual machine in Singapore comes out), but this is just an engineering deep-dive into how we make our security tokens work. It’s a tokens nerd post.

Honda's F1 engine technologies that enable >50% thermal efficiency (global.honda)
Rather than being unrestricted, the development of power units for Formula 1 racing is governed by regulations. In 2014, the F1 adopted regulations that restricted fuel flow to a maximum of 100 kg/h to reflect the global spread of increasing environmental awareness. This meant that development had to focus on how to generate the most energy from a limited supply of fuel. In other words, it created an even greater need to pursue combustion efficiency.
