How to quarantine and reverse suspicious firmware updates on smart locks using only a spare rpi and free tools

I once had a smart lock begin acting strangely after an "automatic" firmware update: intermittent reboots, slower response, and a few unrelated access logs that didn't make sense. I didn't panic — I grabbed a spare Raspberry Pi, isolated the device, and treated the update as potential malware. Over a long evening of testing and reversing, I developed a repeatable workflow that lets you quarantine suspicious firmware updates from a smart lock and reverse-engineer them using only a spare RPi...

Understanding model distillation: make your LLM run fast on a laptop without cloud costs

I remember the first time I tried to run a modern language model on my laptop: it was slow, memory-starved, and I spent more time swapping RAM than actually getting useful responses. Since then I’ve tested pruning, quantization, on-device runtimes and — most importantly — model distillation. Distillation is the technique that finally let me run capable models locally without paying cloud fees or sacrificing privacy. In this piece I’ll...

Hands-on test: which USB-C hubs actually preserve Thunderbolt performance?

I’ve been pairing laptops, docks and external displays for years, and one recurring frustration is the gap between what manufacturers advertise and the real-world bandwidth you actually get from a USB-C hub when you need full Thunderbolt performance. I set out to test a selection of popular USB-C hubs and docks to answer a simple question: which ones truly preserve Thunderbolt bandwidth for external SSDs, 4K/5K displays and high-speed...
