Focus

I have a question: what percent of the time is needed to be online or even just on a computer for doing all the pieces of a web software startup? I'd go with 20%, maybe less. And it would probably work better that way without a browser just a click away, ready to steal countless hours that would make the difference between making progress on a project and learning about HN members' workspaces.
(I have a theory that HN is really a devious ploy by pg to divert the attention of wannabe web entrepreneurs from getting stuff done so that his YCers don't have competition.)
related question - are there mac utilities that can do this during configurable hours of the day?
My guess is that you could couple that with AppleScript and an iCal alarm to start Concentrate every morning.
You don't set hours of the day, but you specify how long you want to "Get Focused". And you can't close the utility via the GUI to keep you honest; it takes a manual SIGTERM to close while in Focus mode.
I've found it very useful, though unfortunately browser support can be flaky. It seems like every major browser release breaks the website tracking and blocking functionality and it takes a few weeks to a few months for the RescueTime utility to catch up. If you don't like using uncommon OS/browser configurations, you'll probably have better luck, though.
I felt guilty writing a script to stop from procrastinating, but it has actually helped tremendously.
