Substack writers, you need a website

https://elizabethtai.com/wp-content/uploads/2026/06/pexels-photo-16622632.jpeg?w=1024
Writers should not make Substack their digital home, as it's short-sighted and can derail long-term visibility on the internet. Instead, they should treat their website as the definitive source of truth and use platforms like Substack as distribution pipes.

Teach yourself programming in ten years (1998)

Learning to program requires a long-term commitment of 10 years or 10,000 hours of deliberate practice, not just a few days or hours of book learning. To become a skilled programmer, focus on hands-on experience, working with others, and continually improving your skills over time, rather than relying solely on books or training courses.

Zig's Incremental Compilation Internals

https://mlugg.co.uk/posts/incremental-compilation-internals/dep_graph_0.png
The Zig compiler's incremental compilation feature allows for fast rebuilds by detecting changed code and recompiling only that, patching the resulting bytes into the output binary. The feature involves caching source files' generated ZIR, tracking dependencies between analysis units, and using a linked file abstraction to handle incremental linking.

Lightweight Spring Boot Monitoring Without Prometheus and Grafana

https://pvrlabs.xyz/img/statlite-dashboard.webp
Running one Spring Boot application or a handful of them on a VPS still calls for basic operational visibility. You need to know whether an application is reachable, whether errors are rising, and whether it restarted. You may not need a complete monitoring platform to answer those questions. Spring Boot Actuator already exposes much of that information. StatLite turns it into a focused ...
