Clone a working Pi SD card to an image file with dd (or Raspberry Pi Imager's custom-image option) and restore it safely onto a new card.
Moving an existing Django project's full toolchain to uv: lockfile, Python pinning, editable installs, and the Docker build-cache wins that came with it.
A concrete comparison of htmx partial updates versus a full Angular SPA for a CRUD-heavy internal tool, and where each one actually wins.
What actually breaks when you turn on CPython 3.14's free-threaded build, and a CI script to catch libraries that silently re-enable the GIL.
A button that reads fine on the breadboard starts firing phantom presses once it's wired into an enclosure. A real debugging session: floating inputs, pull resistors, grounding, and the hardware + software debounce that actually fixes it.
RPi.GPIO sees less maintenance now and breaks outright on the Pi 5 without a shim. A practical porting guide to gpiozero and libgpiod v2, with API differences and a worked before/after of a real LED + button script.
Benchmarks and RAM/thermal limits from running quantized 0.5B-2.7B LLMs on a Raspberry Pi 5 with llama.cpp -- realistic tokens/sec, and when it's genuinely not worth it versus a cloud API.
A concrete migration story: splitting a Django-API + Next.js two-pipeline setup back into one htmx-powered Django app, and the deploy pain, state-sync bugs and duplicated validation that drove it.
Headless Raspberry Pi setup in 2026: Imager's advanced-options panel vs hand-written boot partition files, what custom.toml replaced, and when to pick Ubuntu Server over Raspberry Pi OS Lite.
In this tutorial we'll see how to change the color of an RGB LED using a button with our Raspberry PI GPIO and Python
