I would like to know your opinions how much time is needed to study so that your knowledge would be up to date and you would not get fired of job? :) I am talking about reading books, blogs, watching screencasts.
It is imposible to learn everything, so the goal cannot be measured by I learn this this and this, and then I can rest, becasue there are tons of those "this this and this".
The time is very limited, as there are lots of other fun activities after work time, those would easily fullfil my freetime, there is rarely a day in my life that I would not have something to do. Hobbies, girls. Later maybe will be family. Plus I like to sleep at least 8 hours per day.
My dream job would be such that during job I would learn all new stuff I need, but I feel that I got most of my knowledge while I was unemployed and during employment time I learn not much comparing to what I learned by being unemployed. I heard there are people who don't study at home, and they learn everfything during work. Also I even know one company where people have time for other things during workday (some play games - I think would definitely use this time for studying).
So I need to figure out what is the minumum required time on average lets say per week. Of course not only time is important, but what exatcly you learn in that time if you can learn quickly then its fine, go to bar and dring beer, if not, sit at home and study :) but its dificullt to measure by amount of imformation, so time would be at least for orientation.
