Running Linux On A Thermostat

When your thermostat comes with Linux running on it, that’s not a hack. When it doesn’t, and you get Linux on there yourself, it most definitely is. This is exactly what [cz7asm] has done. In a recent video, he shows the Honeywell thermostat booting Linux and running a wide range …read more

Turn Your Car Into A Simulator

Video games, while entertaining to be sure, are a great way to experience things that could not easily be recreated in real life. Shooting aliens on a giant ring in space is an obvious example, but there are some more realistic examples that video games make much more accessible, such …read more

Raspberry Pi Streams Music Using Only the Default Linux Tools

Getting a  home music streaming system off the ground is typically a straightforward task. Using Apple devices with Airplay makes this task trivial, but if you’re a computing purist like [Connor] who runs a Linux machine and wants to keep it light on extra packages, the task gets complicated quickly. …read more

Automated Tuning Of Linux Audio

Audio systems in Linux are terrible. You’ve never known true pain until you’ve tried to set up a recording or broadcasting workstation running Linux. I did, twenty years ago, and nothing has changed since. This wasn’t really a problem when Linux was either used in server spaces or some nerd’s …read more

Bye Bye vi: GNU/Linux Distros Drop Support

If you grew up with Unix systems like we did, you’ll be sorry to hear the news: vi, the noble text editor that has served us so well these 40 years, is going away — from many GNU/Linux systems, anyway. As of this writing, GNU/Linux Mint, Debian, Ubuntu, and OpenSUSE …read more

Reverse Engineering A Modern IP Camera

Security cameras used to be analog devices feeding back into a room full of tiny screens and commercial grade VCRs. As technology moved forward, IP cameras began to proliferate. Early models simply presented a video stream and configuration page to the local network. Modern models aimed at the home market …read more

Octavo Systems Shows Off With Deadbug Linux Computer

Once upon a time, small Linux-capable single board computers were novelties, but not anymore. Today we have a wide selection of them, many built around modules we could buy for our own projects. Some of the chipset suppliers behind these boards compete on cost, others find a niche to differentiate …read more

New Part Day: The STM32 That Runs Linux

There are a lot of ARM microcontrollers out there, and the parts from ST are featured prominently is the high-power builds we’re seeing. The STM32F4 and ~F7 are powerhouses with great support, and the STM32F0 and the other younger children of the family make for very good, low-power microcontrollers. Now, …read more

Command Line Utilities… in the Cloud?

Although many people think of Linux-based operating systems as graphical, really that GUI is just another application running over the bare operating system. Power users, remote administrators, and people running underpowered computers like a Raspberry Pi have a tendency to do more with command line tools. [Igor] did a FOSDEM19 presentation you can see below about how he’s providing web-like services to the command line using web servers and curl as a client.

This is subtly different from just accessing an ordinary web server via curl. The output is meant for display in the terminal. Of course, you could also …read more

Linux Fu: Easier File Watching

In an earlier installment of Linux Fu, I mentioned how you can use inotifywait to efficiently watch for file system changes. The comments had a lot of alternative ways to do the same job, which is great. But there was one very easy-to-use tool that didn’t show up, so I wanted to talk about it. That tool is entr. It isn’t as versatile, but it is easy to use and covers a lot of common use cases where you want some action to occur when a file changes.

The program is dead simple. It reads a list of file …read more
