This page provides instructions for running AI models powered by Hailo NPUs on Raspberry Pi 5. The Hailo NPU is an AI accelerator chip designed to run neural networks; instead of Raspberry Pi’s CPU doing the AI work, the NPU handles it more efficiently.

Using **fbi** to show a custom splash screen during boot. Take a look at the comments for further configuration to tune it up more.

Suppose you are running a Python systemd service that opens some file descriptors (these can be regular files, named pipes, sockets, and so on). When the service is stopped, it needs to finish cleanly by closing and/or removing the associated resources. This post presents two manners in which the service may be stopped gracefully.

One of our customers designing an embedded Linux system with specific audio needs had a use case where they had a sound card with more than one audio channel, and they needed to separate individual channels so that they can be used by different applications. This is a fairly common use case, we would like to share in this blog post how we achieved this, for both input and output audio channels.

More into the side of how to ensure that the Raspberry Pi 5 behaves correctly having an Ollama service running. Memory, CPU, Temperature... very interesting to have control over the hardware behaviour, to peek on what's important to control.

how to use inotifywait to monitor a directory tree for changes. For instance, we’ll see how we can detect when a new file is created.

Answer in a Raspberry Pi thread regarding rsync running as a daemon in the remote machine

The NSLU2 is a small and silent, ARM CPU powered network storage server that does not have disk storage built in - you need to attach one or two external USB hard drives to it's USB connectors on the back. It is one of the many relatively cheap solutions for out-of-the-box network storage demands. It has a spartan administrative user interface, and is not customizable. However, it's firmware is built on Linux so the source code modifications have been made available to the public. Initially, there was only the “unslung” firmware alternative which enables you to add additional software to the device

A collection of concise write-ups on small things I learn day to day across a variety of languages and technologies. These are things that don't really warrant a full blog post. These are things I've picked up by Learning In Public™ and pairing with smart people at Hashrocket.

It's an interactive Unix filter for command-line that can be used with any list; files, command history, processes, hostnames, bookmarks, git commits, etc.
