Flatpak: pre-assembled furniture applications for Linux

February 23rd, 2018 by

Flatpack is furniture you build yourself. Flatpak is preassembled applications for Linux. This is apparently not at all confusing. (image thanks to https://www.flickr.com/photos/51pct/)

Flatpak provides Linux desktop applications in a secure sandbox which can be installed and run independently of the underlying Linux distribution. Application developers can produce one Flatpak and select the versions of libraries that their application is built, tested and run with so it’s easy for users on any Linux OS to get whatever was intended by the application developer.

Flathub is a distribution service to make sure that Flatpaks are available for popular Linux desktop applications, and at its heart is a private cloud running BuiltBot which builds popular Linux and free/open source desktop apps in Flatpak format. This lives in Mythic Beasts’ Cambridge data centre.

At Mythic Beasts we like this idea so much we offered them lots of free bandwidth (100TB) to help get them started. We’ve now upgraded this with a pair of virtual machines in our core Docklands sites to provide redundancy and more grunt for traffic serving.

Some of their users noticed and were appreciative immediately:
