Hello again! I want to start doing “Status update” style articles and more writing in general so I thought I’d announce on here the main project I’ve been working on recently amongst all my other open source work. Magnolia is a new UI toolkit written entirely from scratch in Zig for Linux desktops. It has a focus on ease-of-use, performance, and supporting older devices. The only runtime system dependencies are X11 and OpenGL....

The original creation date on this article is 17 Jan 2022 and I’ve been running NixOS 21.05 since then. Previously I’d been running a mix of Debian and Ubuntu and I don’t think I’ll be switching back anytime soon. Granted, I have not officially performed an update in that time, though I do not suspect it going badly in the ways that other distributions have bricked my Linux installs in the past....

This post assumes you’ve already read Generating a PGP key. I’ll be using my key for these examples but you’ll want to replace 95535225B55B5A9F39E29F5EDAB85EABB6014D3F with your own in the commands. For adding it to github run the following and copy the whole output. gpg --armor --export 95535225B55B5A9F39E29F5EDAB85EABB6014D3F That will generate a very long wall of text encapsulated by -----BEGIN PGP PUBLIC KEY BLOCK----- -----END PGP PUBLIC KEY BLOCK----- Then navigate to https://github....

For this we’ll be using GnuPG, aka GPG, which is a common implementation of the PGP spec. $ gpg --full-generate-key As this will be your master key, make sure to pick RSA and RSA, 4096 bits, and does not expire for the generation options. Once it is complete, it will print the details of it. Here’s what I got as an example. pub rsa4096 2021-03-21 [SC] 95535225B55B5A9F39E29F5EDAB85EABB6014D3F uid Meghan Denny <hello@nektro....

Vagrant is an application to enable you to programmatically control VM’s Hashicorp calls Vagrant Boxes. It’s hayday was before the rise of Docker and Kubernetes but still has great use cases. For instance, Docker Images have to be based on the Linux Kernel. So since Vagrant Boxes are full VM’s, they can contain a wider selection of operating systems for you to choose from. # install vagrant itself, it will use the libvirt provider by default $ sudo apt install vagrant # install the libvirt daemon and enable it sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system virtinst bridge-utils sudo systemctl enable libvirtd sudo systemctl start libvirtd # add yourself to the libvirt group sudo usermod -aG libvirt $USER # and you're all set!...

Run $ sudo dmesg | grep 'firmware load for' | grep 'failed with error' $ sudo dmesg | grep 'firmware: failed to load' This will search your diagnostic kernel logs for failed firmware loads and will produce lines that look similar to the following [ 53.168802] bluetooth hci0: Direct firmware load for qca/rampatch_usb_00000200.bin failed with error -2 Take that file name and pass it to $ sudo apt-file search qca/rampatch_usb_00000200.bin Which in this case will yield...
