Mr Tides

This sounds like an excellent and well conceived app to tell surfers, fishermen and paddlers the time of the tides and the details of currents all around the world. Linked to a central database, the times are supposed to be highly accurate. The only problem I can foresee with this software is a tsunami. I think Mr Tides would be somewhat out of its depth when the big one hit shorelines.

Sleepless HD

Technically speaking SleeplessHD is an application which recurrently triggers a selected harddisk to keep it spinning and prevents the internal sleep mechanism of some harddisks from taking effect.

Before you glaze over, pay attention to the icon from Braintrigger. Smoking!!!!!

Shrook

Shrook is to RSS readers what Shrek is to ugliness, it rocks. It is a Mac app, but one of its killer features is synchronisation. With a shrook.com account and synchronization, you can log in from any web browser, and all of your channels will be there. It has up-to-date information on what you've read, and when you get back to Shrook itself, it'll know what you looked at when you were away.

We already waste 3 -5 hours a week reading blogs at work. With Shrook, when you get home, you can keep adding feeds so that you can then spend 4 to 6 hours or more reading even more blogs in the workplace. Perhaps this app is not suitable for work!

Freeware is a wonderful thing - in the right hands.
