Issue #147 / Feb 2013

As these pages go to print, I notice that we have reached issue 147. The number 147 might not seem particularly noteworthy to the rest of the world, but I noticed it. You see, the first issue with my picture on page 3 was issue 48, and if you count by ones from the beginning of the issue 48 cycle to the end of the issue 147 cycle, you get to 100 issues. This number 100 is always good for a milestone moment in our base 10 universe. Celebrating a numeral is not so important on its own, but having these reasons to look back can provide some context for looking ahead into the future – or looking around at the present.

Linux Mint 14 “Nadia”

Linux Mint is a wildly popular Ubuntu-based desktop Linux with an emphasis on simplicity. Along with a strong assortment of open source applications and utilities, Mint takes pains to provide proprietary drivers and other helper tools for seamless-as-possible operations. The Mint 14 release features a new Windows Quick-list app for managing windows across multiple workspaces, as well as Alt+Tab window-switcher virtualization and a handy notification tool. Also debuting with this release is the new Nemo file browser, a fork of Gnome’s Nautilus file manager based on the Nautilus 3.4 codebase.
