I hate getting distracted. But with the increasing addictiveness of the web it’s becoming harder to prevent myself from reflexively checking sites like Facebook and Hacker News. That’s why I was excited to see a nice Python script called focus.py that acts as a DNS and schedules firewalls to prevent users from wasting time. I can block entire domains and specify timeframes during which they are allowed.
I wrote “Stay focused” on my local homepage. Annoying Facebook share and like buttons have also delightfully disappeared from my world.
My only complaint about focus.py is that I need to run it everytime the computer reboots. Another
method, if I don’t trust my self-control, is to modify
/etc/hosts. But unlike Linux, OS X Lion
doesn’t support wildcards that would block entire domains like *.facebook.com. I’d have to add a
new line for each distinct subdomain.
Follow Homebrew’s post-installation instructions and check dnsmasq is running with
ps aux | grep
dnsmasq. Now, we need to configure OS X to add 127.0.0.1 to our DNS Servers. Go to System
Preferences > Network > (Select Connection, i.e. Wi-Fi) > Advanced > DNS. Add, in order,
127.0.0.1, 126.96.36.199, and 188.8.131.52. The last two are Google Public DNS servers. I have to list other
real name servers in addition to localhost, but these change based on what network I’m on. So it’s
unreliable to list local name servers such as routers.

There’s no way to schedule a break for myself, but I think I’ll live.
