Installing third-party software on distributions
Most of the big Linux distributions do have some method (or multiple methods) for acquiring third-party (sometimes unvetted) software.
Some of these third-party repositories are cross-platform, meaning they run on almost all distributions,
while others are specific to one family of distributions.
Examples of distro-specific, third-party repositories,
the Fedora Project has Copr,
the Ubuntu family has Personal Package Archives (also known as PPAs),
the openSUSE community has a variety of third-party repositories, and
The various BSDs have port collections which are usually semi-open to outside contributors.
Other repositories which are more portable and work across most distributions.
Snap packages.
Almost all desktop distributions can run portable desktop applications in the form of Flatpak bundles and these bundles can usually be found in the Flathub repository.
The Nix package manager can be installed on most Linux distributions and provides access to over 60,000 Nixpkgs.
There are also operating system agnostic port collections such as pkgsrc.

How to Protect Kids’ Ears From Headphone-Related Hearing Loss
Standard earbuds are more concerning because they don’t block out background noise as well as over-the-ear headphones, with their foam ear cups.
Studies have shown that people on average turn up the volume of their earbuds by 13 decibels above the background noise
That’s fine if you’re in a classroom, where the average sound level is 60 decibels, but if you’re on an airplane, where it can be 80 decibels, the music in your earbuds could end up louder than a lawn mower.
Follow the 80/90 rule.
Audiologists say children can listen to their devices at 80% of the maximum volume for 90 minutes a day.
You can eyeball this by looking at the volume slider on your tablet or phone.
If your child is going to listen to a device for longer than 90 minutes a day, experts advise limiting the volume.
You can also choose to receive notifications if the headphone audio level exceeds the WHO’s recommended audio limit over a seven-day period.
