Dollar budget at least $500 a year of O'Reilly books. Time budget a couple nights a month at the bookstore looking through O'Reilly style books. Experiencing fantom Blackberry buzz. You could understand the full stack (and often had to), but you also experienced it in reduced, elephant eating chunks. The last time I was managing people it was tricky, how do I fill all the gaps in my peoples knowledge? I went from serial terminals to thicknet XWindows, to hubs, to switches. I went from writing your own OS and writing to floppies in your own format to server farms. For someone today, you can't possible just know all those pieces that I slowly got introduced to.
