I’m an author (well, an engineer who writes about what I do). And when I’m writing I need privacy, peace and quiet – so I can focus. I recently realized that I write the best on airplanes where there’s no wireless, no Internet and no calls. I can just put on my headphones and sit with man pages and virtual machines and crank away. Now there’s an app that can help me to mirror that experience. Self Control allows me to block access to mail and the web, almost mirroring (minus the phone and baby and other distractions) that which I have on an airplane. So why not just unplug…
