A few days ago my ISP broke the IPv4 connectivity from my router after a power cut. Fortunately IPv6 connectivity still worked fine, but only a small fraction of websites were accessible.

In this post I'll cover how Linux, WireGuard, and Hetzner came to the rescue - keeping the whole internet usable with only an IPv6 connection.

In this post we will use agentic AI (with Cursor and Claude 4 Sonnet) with two MCP servers to complete an old Data Engineering take-home assignment. It's time to put Claude to the test!

The Docker environment and notebook used is available in my dataeng_assessment_mcp repo.

In this post we will create a basic Wifi-controlled car with an ESP32 development board and ESP32-CAM camera module, and all of the code written in Rust.

All of the code for this example is available on Github in my esp32_wifi_tank repo.

In this post we will create a basic ESP32 project using Rust and espup.

We will write a Snake game to run on an ESP32 development board with a connected OLED display and controlled with a joystick.

The code for this example is available on Github in my snake_rust_esp32 repo.

Recently I wrote my first Clippy lint. It was much easier to implement and test than I had expected. In this post I'll review the process of creating or contributing to a Clippy lint, the implementation itself and how this reflects Rust's values of empowerment.

I was recently reading more about the lambda_runtime crate and came across this issue where it is mentioned that the #[lambda] procedural macro can be misleading and cause problems if used naively.

In this post we will implement our own simple custom runtime for AWS Lambda in Rust, and understand the reasons behind this issue.

The code used in this blog post is available on Github in my micro_lambda repository.

Doing projects is often the best way to get more programming experience and learn about new concepts and problem domains. However, a common issue is finding feasible projects of a reasonable scope that can produce something useful in a few weekends.

In this post I will list some classic project ideas for beginner and intermediate programmers (most of which should be achievable in 2-3 weekends), along with many other project ideas I've had but have never had time to implement (and a few which I did).

There are many long lists of project ideas available on Github, like build-your-own-x and 100 Projects of Code but these often lack a real description and justification of the projects. In this article I will go more in-depth with the different project ideas.

Within each section the projects are ordered in ascending difficulty / time investment.

The Rust core team recently released a call for blog posts as part of the 2021 roadmap for Rust. In this post I will detail my own experience with Rust, and areas I'd like to see improved during 2021.

I recently had an ongoing issue with the deleted CacheDelete daemon using huge amounts of CPU time almost constantly. This post covers how I fixed it and a few tips for OS X recovery and performance improvements.

This post covers why I believe local and national governments should adopt and invest in Free and Open Source Software (FOSS).

This has been in the news recently due to the city of Munich renewing it's LiMux Linux distribution thanks to an agreement between the local SDP and Green politicians, and the efforts of the Public Money, Public Code campaign.
