re: If you could do it again, what would you study in college?

Big no. I sat in 3000 and 4000 level classes at LSU in ISDS in the early 2000s that were completely smoked by Microsoft and Cisco testing and real life. Not one mention of the OSI model. IT college stuff teaches you jack shite. Sitting in a 4000 level ISDS being asked to define the difference between a LAN, a MAN, and a WAN? I could have taught the class that in a day. Are you kidding? Total garbage.

Solve business problems. Don't apply service packs to MS SQL databases during the workday. Don't trust power cable labels that are to actually lead to the server or switch you're trying to unplug.

Please send me $100k for four years worth of bullshite education. Give me another six weeks, I can teach you the rest, if you care. Trash, and it's not just LSU, it's nearly all graduates, from any school. They have NO IDEA WHAT THEY'RE DOING. Particularly about *enabling the business.* I really DGAF if you know Ruby on Rails, C#, etc., but if you're too obtuse (I tried to use a nice word) to notice that there are terabytes of data being sent to eastern european or russian sites every week, and think your priority is some random low level shite (can you install your own printers, can you change your wallpaper, etc.) then you deserve a plant help desk job where you pull on plastic sleeves when you head into the unit in August.

IT in college is worthless. Install ISDN/T1/DSL etc., for six months, troubleshoot basic networks for another six months, learn not how to be an a-hole, and you're golden.
