An overview of parallel programming (Go edition)

In practice, the software we write runs on several processors. Unfortunately, much of what we take for granted on a single processor becomes false when there are more than one processor. For example, if two processors modify the same piece of memory, what…

Arch Linux: Recent news updates
Cleaning up old repositories

Around two years ago, we've merged the [community] repository into [extra] as part of the git migration. In order to not break user setups, we kept these repositories around in an unused and empty state. We're going to clean up these old repositories on 2025-03-01.

On systems where /etc/pacman.conf still references the old [community] repository, pacman -Sy will return an error on trying to sync repository metadata.

The following deprecated repositories will be removed: [community], [community-testing], [testing], [testing-debug], [staging], [staging-debug].

Please make sure to remove all use of the aforementioned repositories from your /etc/pacman.conf (for which a .pacnew was shipped with pacman>=6.0.2-7)!
