Tales from the Sysadmin: Dumped into the Grub Command Line

Today I have a tale of mystery, of horror, and of hope. The allure of a newer kernel and packages was too much to resist, so I found myself upgrading to Fedora 30. All the packages had downloaded, all that was left was to let DNF reboot the machine and …read more

Worn Out eMMC Chips are Crippling Older Teslas

It should probably go without saying that the main reason most people buy an electric vehicle (EV) is because they want to reduce or eliminate their usage of gasoline. Even if you aren’t terribly concerned about your ecological footprint, the fact of the matter is that electricity prices are so …read more

Linux Fu: Python GUIs for Command Line Programs (Almost) Instantly

Not every programmer likes creating GUI code. Most hacker types don’t mind a command line interface, but very few ordinary users appreciate them. However, if you write command line programs in Python, Gooey can help. By leveraging some Python features and a common Python idiom, you can convert a command …read more

Linux Fu: Shell Scripts in C, C++, and Others

At first glance, it might not seem to make sense to write shell scripts in C/C++. After all, the whole point to a shell script is to knock out something quick and dirty. However, there are cases where you might want to write a quick C program to do something …read more

Linux Fu: Interactive SSH Applications

[Drew DeVault] recently wrote up some interesting instructions on how to package up interactive text-based Linux commands for users to access via ssh. At first, this seems simple, but there are quite a few nuances to it and [Drew] does a good job of covering them.

One easy way — …read more

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

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

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
