The excellent time tracking app OfficeTime is on sale today at MacUpdate Promo. I had actually considered buying it two weeks ago when I needed a time tracking app but went with On The Job instead as it was half of the other tool's price. In typical fashion I've since wished I had OfficeTime due to the increased functionality but am now stuck with On The Job. Doh.
I've just found a cool little Java app (installers available for Windows, OSX) for validating web sites called the Total Validator Tool. And it's free (though not open-source) so it's even better. Another tool to add to the utility belt.
