Posted on 2013-03-18 by

The Mate desktop really lives up to its promise of a “traditional desktop”, compatible in look and feel with Gnome 2.X versions. After running it for a few hours now, I’m sold. I never really liked Unity very much, so … Continue reading →

As part of the ‘utility’ library in one of the projects we are using at work, I wrote two small wrappers around strtol() and strtoul(). These two functions support a much more useful error reporting mechanism than the plain atoi() … Continue reading →
