Do you like surprises?
Tony Robbins asked his audience in a TED talk if they like surprises. He received a resounding "YEAH", but he continued with the comment: "BULL****, people like only the surprises they expect". Let me tell you about two developer's surprises from yesterday (I guess, I didn't like those much):
Oracle Surprise: I use tnsnames.ora to connect to Oracle and tnsping.exe tells me to what service I am currently connected to. It turned out that this is not always reliable if you have multiple tnsnames.ora. So, I have been working for quite a long time on a database that was not the one I expected. More info on the topic here and here.
The developer's job is not short of surprises, so better approach them with eagerness or join a club like this one.
