The recently released Mint 16, nicknamed Petra, might be the perfect Linux desktop for newcomers. At its core is Ubuntu 13.10, but on top of this are desktops Mate and Cinnamon, the latter being the Mint project's homegrown user interface. Ubuntu gives a stable foundations on which to build, allowing the project to focus more on its desktops and less on the underpinnings. The result is a pair of desktops both worthy of consideration but with Cinnamon far more interesting as its hits version 2.0

In the era of "big data", large text files (GB or more) could be commonly encountered around us. A typical text editor may not be designed to deal with such large text files efficiently, and may simply get choked while attempting to open a big file, due to insufficient memory. If you are a savvy system admin, you can probably open or touch an arbitrary text file with a combination of cat, tail, grep, sed, awk, etc. In this tutorial, I will discuss more user-friendly ways to open (and possibly edit) a large text file on Linux.

The battle between the good guys and bad guys is a never-ending one. And as they say in the industry, if you have something that somebody wants to gain access to badly enough, they will keep taking shots at it until they succeed.

Last year, a third of honeybee colonies in the United States quite literally vanished. Commercial honey operations, previously abuzz with many thousands of bees, fell suddenly silent, leaving scientists and beekeepers alike scratching their heads. The reasons remain mostly a mystery for what is called Colony Collapse Disorder—a disturbing development of the drying up of beehives throughout the industrialised world. Unfortunately, there's a lot more to the problem than simply running out of honey. Bees are one of the most abundant pollinators in the natural world. They are the unsung, unpaid facilitators of human agricultural practices and have been for as long as we have sewn seeds. Their disappearance would spell disaster for our food supply, with some estimating our species lasting only four years on this planet without them. So, what can be done?

It kept nagging at me. Why was the "hot corner" in Debian's version of GNOME 3 so "sensitive," compared to the GNOME 3 desktop's hot corner in Fedora 19? I did a bit of searching and found out that "hot corner" sensitivity was something that the user can set, not in stock GNOME 3 but with the Activities Configurator extension.
