duct tape programming

Everyone thinks it at one point, "It's ugly, but it will work" and the next though is "I'd like to make it better, but I don't have time right now".
Now it has a name: duct tape programming

It's always a trade off, between two extremes:
wasting time on something that already works
vs
writing something that will fall apart with the next modification (or in a different environment)

It's important to be aware of the decision you are making.
