Every tutorial has the same weak spot: the code sample. A static block shows what the code looks like. It cannot show what the code does. The reader has to copy it, open an editor, paste it, and run it — and every step in that chain is a step where a...

Tailscale SSH is a popular feature in homelab setups because it lets you ditch traditional SSH key management entirely and lean on your Tailnet's identity model instead. That makes the recent security investigation and remediation update worth paying...

I start in an empty folder with a fresh Claude Code and teach it to make images, voices and music, and to edit them with FFmpeg. At the end it makes a 101-second narrated space story. Every prompt I used is here, ready to copy. The way of the Jedi ...

Most people who search for a "Twitter scraper" don't need the whole firehose. They have a list of tweet URLs a launch, a campaign, posts from a few creators and want to know how many likes and replies each one has, and how that changes over a week. T...

I've been learning Python by building a video clipping CLI application, and along the way I've ended up learning a lot more than I expected. Some of it was straightforward. Some of it made me stop and think, especially when I first started writing t...

I've been learning just recently. I came across it while setting up a Python project and looking for a simple way to collect all the commands I use during development. This started with something I got used to in Elixir. One of the things I really...

"How do I scrape TikTok?" usually means one of three things: follower counts for a list of creators, the latest videos from an account with their views and likes, or tracking how those numbers change over time. This guide builds that in plain Python,...

What Is a WAF and How Does It Work? A Plain-English Guide If you run a website, you've probably been told to "put a WAF in front of it." Here's what that actually means — no jargon. What "WAF" stands for A Web Application Firewall protects your a...

RS232 and RS485 both turn up on the same vehicle-terminal spec sheet, and integrators routinely wire the wrong one. The choice is not about speed or age. It comes down to two questions: how many devices are on the line, and how far does the cable run...

Watch a matatu conductor work for one trip and you will see a programmer at full speed. He counts heads. He knows the fare. He takes a KSh 500 note from someone who owes KSh 70 and hands back the exact change without a pause. He also decides, by feel...

> Is your agent worth evaluating? If so, how much should you invest—and how do you ensure the evaluation actually serves the business? 1. Is Your Agent's Work Worth Evaluating Yet? Many teams miss this fundamental question: does your agent actually...

"They used it once and refused to touch it again." When that feedback landed two weeks in, I could barely believe it. An agent validated against a benchmark built on real-world data had still failed to solve the foundation’s workflow problem. Only ...

If you've written JavaScript for a while, you've probably fought with Date at some point. It's one of the oldest parts of the language, barely changed since 1995, and honestly, it shows. Let's look at why it causes so much pain and how the new Tempor...

Reading about a SQL injection isn't the same as triggering one yourself and watching the database dump on screen. That's why I built my own home lab, and why I wrote this guide to help you build yours. A cybersecurity home lab is a small, self-conta...
