Worst working conditions you have written code in?
nl: A hot, noisy hotel room, dial-up internet, 4:00am writing in _VB6_ to connect to some weird COM+ service that used VB calling conventions, then a C++ COM wrapper for that, then a C wrapper to connect to a Java JNI service. At 8:00pm I didn't know VB, either. And it had to work by 9:00am when some system it interfaced to started up. Oh - and I couldn't actually test it against anything but stubs.
