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.

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.

Best IDEs for Octave, Python and R

Best IDEs for Octave, Python and R

Code-wise, I’ve been getting my hands dirty with some digital grease over the past few months, and it’s been fun.
