What do you do during compiling? (for professionals)

[Sentinel]

A question for professional developers.
What do you do during compiling?

A lot of time is spend during the compilation of code.
Do you just wait and look around? Do you scribble
notes on a paper? Do you type in a different window?
Do you surf in the net?

Thanks for sharing information.

I try to work in tiny test modules until the very end to avoid long compile times. When faced with a long compile time (more than 5 min) I work on something else. < 5 min I mostly goof off, like coming here … :P

My current job has me programming in Scala and C++. So, during compiling, I am programming in C++.

*for those who don't know, Scala's compilation times make C++ look blazing fast

Luckily the compile time for the main project I work on only takes around a minute (The "fundamental" parts of the product are already built, which are only rarely changed.)

Usually I just cross my fingers while VS builds each project in the solution. Or pull my hair out when it fails. But the whole process of building + exporting data can take a decent amount of time (over a GB of info is zipped and copied, and then installed on another computer); I'll usually write notes down concerning what I'm changing or testing to help keep track of what I have to do.
