Ages ago I wrote a tiny portscanner in bash2 shell script, taking advantage of an odd feature in bash2 that allows one to write network code with filesystem operations. For those with a high pain threshold, this feature can be used to write two-way TCP client code for DailyWTF-style solutions.
An adserver ignores its provided parameters. And a programmer, somewhere, pulls air through his teeth making a loud “hisssshhh” sound.
TimeGuard is a small command-line utility (written in PHP) that quickly turns off and on access to certain websites. There are desktop applications that do this already, but TimeGuard is free and easier to use for people that already have terminal windows open. Typical usage:
$ sudo timeguard on
And all of the sites configured disappear.
$ sudo timeguard addsite slickdeals.net
And poof! slickdeals.net is no longer available.
Prior to writing and using this, I figured it would not make much of a difference. I noticed though that the effort required to disable TimeGuard was just enough added resistance to get me back on track, typically. More tricks to tame the amygdala.
