The magic behind snap interfaces

Ubuntu Article

Snaps are confined, self-contained applications, designed with portability and security in mind. By default, strictly confined snaps run in isolation, with minimal access to system resources. For instance, they cannot access home, network, audio, or display. To make their snaps usable, developers and publishers can declare a set of interf ...

Hey snap, where’s my data?

Desktop Article

Snaps are self-contained applications, isolated from the underlying operating systems by several layers of confinement. This mechanism introduces security benefits, but it may also create confusion for people who are less familiar with how snaps work and behave, especially when it comes to filesystem access. Today, we’d like to clarify so ...

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

Desktop Article

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. As it happens, the former group also tends to rarely reinstall their system when problems occur, while ...

What’s in a snap?

Desktop Article

Snaps are several things, all at once. They are confined, standalone Linux applications that bundle all their necessary dependencies, which means they do not need to rely on the underlying system, and can run independently of it. Snaps are also packaged as compressed Squashfs filesystems, using the .snap extension. For most users, they ar ...

I bought a computer game called F-16: Combat Pilot, a flight simulator featuring free-flight, five types of single-player missions, a full campaign mode, serial-port multiplayer, and then some. Gloriously wrapped in four colors and magnetized on two single-density 5.25-inch floppy disks. Total size: 680 KB. Nowadays, it ...

How to keep your Linux disk usage nice and tidy and save space

Desktop Article

Everyone loves a clean, tidy home (hopefully). This also includes your other home – slash home, the Linux home directory. Disk cleanup and management utilities are extremely popular in Windows, but not so much in Linux. This means that users who want to do a bit of housekeeping in their distro may not necessarily have ...

Productivity corner: editors, editors, editors

Text editors are a curious product. On one hand, they are simple, no-nonsense digital pads for taking notes, without any embellishments or visual styling. On the other, they are powerful code and data toolboxes, allowing for a great deal of flexibility and innovation. Indeed, software developers, Web developers and entrepreneuring nerds w ...
