  • My 30-Year Quitting Addiction
    There is a free and open source app called SelfControl for macOS. It allows one to block access to any site one adds to the list in the app for the amount of time the user chooses. Attempt to use multiple browsers, restarting one's machine, deleting the app, etc. won't get around the block either. It's been super helpful for me, so I thought I'd just throw it out there. https://selfcontrolapp.com. - Source: Hacker News / over 2 years ago
