Woody asks: "It's common knowledge that the development environment should be the same as the test environment which should mimic the production environment whenever possible. I'm currently working on a project where we develop on Dell, test on IBM, and the production system is up in the air. For embedded systems the differences can be running on a VM versus running on the actual hardware. What I want to know is what kind of problems have Slashdot readers been faced with because of different environments being used for different phase of their projects, and how have they been overcome?"
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
