Good IC / Electronic component inventory software?

Smerky writes: As I've been getting more and more into hobby electronics I have been finding it difficult to keep track of all the different ICs and other electronics that I have (resistors, capacitors, etc...). What are slashdoter's recommendation for some inventory software? Certain qualifications that I'd be looking for personally are that it has to run on Linux/OSX well or be web based (To run well on an Apache2 server).
