Mark over at his blog, made a nice handy Mac widget called Salinity. It is used to calculate approximate salinity based on your hydrometer reading. It takes into account the current water temperature and the hydrometer’s calibration temperature. Pretty nifty eh? For the record I took my mac I bought back to the Apple store, it was fan-less and my legs couldn’t handle it. Until Steve Jobs admits that they need to put a cooling fan in, Apple is off my it list. However Mr. Tang that Mark keeps in his 45 gallon (hurry get your 65 gallon up and running, your 45 is way to small for him!) is on my list and now I am hideously jealous.
