yeah, I find this piece of software very usefull. I call for free my family at home when I am travelling with very good quality of the call. It is fine, just test it.
Well this one beats them all. It is simple (actually plain looking) but incredibly powerful and complete. Lots (and I mean LOTS) of scientific constants from NIST. Complex numbers are even supported for science, and all the functions I need.
An outstanding tool that converts pretty much anything and calculates in the same operation. Its on/off startup mode makes it a true popup calculator: pick a hot key then use the same key to turn AddUp either on or off. It's pretty awesome.
The dllshow is just awesome!!! It works like a charm. I was trying to snoop into some dlls and was able to figure out how to hack into Bank of America.
