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,

  • 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.
