How’s my snap faring on different distributions?

Ubuntu Article

The life of an application can roughly be divided into two: everything that happens before it goes live – building, packaging, publication – and then, everything that happens after that milestone. Traditionally, on Linux, developers didn’t always have an easy way of deriving useful numbers on how their software was doing across the distro ...

Hey snap, where’s my data?

Desktop Article

Snaps are self-contained applications, isolated from the underlying operating systems by several layers of confinement.

Should you ever reinstall your Linux box? If so, how?

Broadly speaking, the Linux community can be divided into two camps – those who upgrade their operating systems in-vivo, whenever there is an option to do so in their distro of choice, and those who install from scratch.
