Usability, user-friendliness and the Linux desktop

A point I’ve been trying to convey about the Linux desktop through my reviews and tutorials is that distribution developers are doing a bad job of giving users all the goodness of what’s available in Linux and GNU software in a manner where the system just works.

Image from SpiderOak.com. In light of ongoing debate about data privacy and security and government surveillance, courtesy of the decision that Edward Snowden made, a significant percentage of users have been flocking to companies that provide some form of security and privacy guarantees.

Microsoft’s Surface RT is an “Unmitigated Disaster.” What’s wrong with that?

Microsoft’s Surface RT is an “Unmitigated Disaster.” What’s wrong with that?

After Microsoft successfully used Restricted Boot to make dual-booting Linux distributions and Windows 8 on newer desktop and notebook computers a painful adventure. And after the company successfully locked out Linux distributions from ARM tablets running Windows RT, any bad news streaming from Steve Ballmer’s office is sweet music to my ears.

Developers: Give us sane and sensible default system and application settings

Developers: Give us sane and sensible default system and application settings

I often wonder why Linux desktops are the way they are. You know, why stuff that’s supposed to work out of the box, don’t and why some of the better features of the desktop environments and applications are buried or not enabled by default.
