Lab Rat Jason writes "During a discussion with my wife last night, I came to the realization that the primary reason I have a Hadoop cluster tucked under my desk at home (I work in an office) is because my drive for learning is too aggressive for my IT department's security policy, as well as their hardware budget. But on closer inspection the issue runs even deeper than that. Time spent working on the somewhat menial tasks of the day job prevent me from spending time learning new tech that could help me do the job better. So I do my learning on my own time. As I thought about it, I don't know a single developer who doesn't have a home setup that allows them to tinker in a more relaxed environment. Or, put another way, my home setup represents the place I wish my company was going. So my question to Slashdot is this: How many of you find yourselves investing personal time to learn things that will directly benefit your employer, and how many of you are able to 'separate church and state?'"
