Diving into the world of Linux naturally led me to discover the vibrant homelab community. What began as casual curiosity soon became a genuine fascination, fuelled by countless YouTube videos showcasing everything from compact, single-board computers to sprawling, business-grade server racks. The creativity and technical depth on display resonated with my own desire to experiment and learn by doing. But as I watched, a set of questions began to form: Did I actually need a homelab? What would I use it for? Did it require a significant investment in hardware? And, crucially, how should I even begin?

When people think of iPhones, they often picture sleek hardware and user-friendly software. Of course, if you’re team Android, that’s perfectly fine—there’s no room for tribalism here. But I digress. Back to the topic at hand: one of iOS’s most underrated features is hiding in plain sight—Apple Shortcuts. This powerful app allows you to automate tasks, saving time and effort on repetitive actions. Yet despite its incredible potential, many iPhone users either tuck it away in a folder or remove it entirely.

It’s only been a few weeks since OpenAI released GPT-4, and I’ve already been putting it to work. As a ChatGPT Plus subscriber, I’ve gained access to this new model, albeit with frustratingly low rate limits that I hope will improve in the coming weeks. Despite that, the excitement I am feeling is real. GPT-4 feels like a gear shift, a real turning point, not just in AI capability, but in how I personally approach learning. I’ve been experimenting with Large Language Models (LLMs) for some time now, mainly to augment my learning around technical subjects. With GPT-4, that approach feels more powerful than ever.

In the fast-paced world of technology, keeping up with new tools, concepts, and workflows can feel overwhelming. That’s why I rely heavily on documentation—it’s not just a task; it’s a mindset. Documentation serves as my second brain, a system I can rely on to store, organise, and retrieve the knowledge I’ve accumulated over time. It helps me stay sharp, grow professionally, and contribute to others’ understanding. Here’s why it’s so important to me and how I approach it.

I’ve been diving deeper into Git recently, using it daily in my current role compared to just every other day in previous positions. While I’ve been comfortable with the core Git commands for a while, my current role has pushed me to explore more advanced Git concepts and techniques. I thought it would be useful to compile this guide as a reference, both for myself and for anyone else looking to sharpen their Git skills.
