Alfie John

Alfie John’s site is a personal homepage and blog rather than a product or service. The landing page collects a handful of essays and links, each with a short teaser, alongside simple contact options for email and Signal. There is no signup, dashboard, or paywall; the content is simply published to be read.

The writing leans toward systems programming and infrastructure. Posts cover running Bitcoin Core from source on Debian, building within disposable deterministic virtual machines, and designing a cryptocurrency exchange without a trusted third party. A recurring thread is skepticism toward weak security arguments, as in the piece on encryption backdoors.

There is also a reflective side: one entry traces how small childhood experiences accumulated into a career as a programmer, and another announces a first post on the Rust Jobs blog with plans to discuss open-source code, tooling, and Lean Startup process.

Readers who benefit most are developers, Bitcoin and Rust enthusiasts, and anyone interested in reproducible builds or privacy-respecting systems. Because posts are occasional and organized as a flat list, the practical approach is to skim the teasers and open only what matches your interests, then check back rarely rather than expecting a steady feed.

Overall it reads like a working notebook from an experienced engineer: opinionated, technical, and unpolished in a way that suits the material.
