Linux Kernel 6.12 Released! Mainline PPA However Broken Again

Last updated: November 19, 2024 — Leave a comment

Linux Kernel 6.12 was released! Linus Torvalds announced on Sunday:

“No strange surprises this last week, so we’re sticking to the regular release schedule, and that obviously means that the merge window opens
tomorrow. I already have two dozen+ pull requests in my mailbox, kudos to all the early birds.

But before the merge window opens, please give this a quick test to make sure we didn’t mess anything up. The shortlog below gives you the summary for the last week, and nothing really jumps out at me. A number of last-minute reverts, and some random fairly small fixes fairly spread out in the tree.”

How to Add PATH Variables in Ubuntu 24.04

Last updated: November 4, 2024 — Leave a comment

This tutorial shows how to configure PATH environment variables. Though title said for Ubuntu 24.04, it works in most Linux systems.

PATH specifies the directories in which the executable files of programs are located on the system. Without knowing or typing the full path to the file, just type the app name in the command line, then your system will look into the path directories and run the first that matches.

For example, type firefox in command line will run /usr/bin/firefox to launch Firefox web browser in Ubuntu, Fedora, and other Linux that use the browser as default.
