Just a quick note to mention that Find It! Keep It! is not compatible with Safari 4.0. When you install Safari 4.0, it updates WebKit in a manner that breaks Find It! Keep It!. I will fix this but given my current workload, it may take me a few months.
Mac Tech just published my article on call stack logging which lets you see which function calls led to my NSLog replacement being invoked. The nice thing is that it works for C, C++ and Objective-C unlike most of the solutions you see elsewhere. The source code should show up on their ftp site some time soon. With few developer magazines surviving (Dr Dobbs webified, BYTE gone), I’m glad Mac developers still have a print magazine to read.
