And that's why I rent servers from digital ocean or linode. However, nobody has yet written http://selfcontrolapp.com/ for OS X but they have written xmonad (the thing that was keeping me on desktop Linux) for OSX.
And no, I can't write self-control on Linux for myself, because then circumventing it to read the news wouldn't require more patient thought than whatever I'm trying to focus on. Please don't discuss how it works in replying to my comment. I want not to know.
