Interesting to note that I would start with just tossing one ball from hand to hand - as soon as you can do that consistently, try two (as in left, right, catch, catch, right left, catch catch, etc). again do that until they look the same in both directions and the heights stay the same and you don't drop them. Then go for all 3, usually starting is the hardest part, and you'll try it a few times before you get the first throw decent.
Sometimes you have to have people stand right in front of a wall to teach them not to throw forward...
I taught myself while home sick from school - took about a week. This was pre internet and I had no references at all other than 3 balls.
He then proceeded to explain that if we chose a) the test would be only require knowledge we had learned in class, b) the test would cover material that would not be answerable from the book or c) where he would choose open NP-hard questions and see how well we did reasoning through possible solutions.
Not surprisingly we chose option a)
The thing that will really piss me off is if I get to 80 or so, then they figure out the anti-aging tech, but I'm too old to use it. I want either to benefit from it or for it to still be "in the distant future" when/if I get old and die.
Running a real mail server for a real company without a correct functioning PTR record would be something that should get you fired.
The reasoning is simple, anyone running a real mail server will easily be able to set it up, if you don't have the PTR it likely means you are a spammer or you are running a server at home. Not that there's anything wrong with running your own SMTP server, but that's basically how botnets send spam...so there's a heavy correlation to that and spam.
- 1) Fire people until everyone is working 40ish hours/week (and are unhappy)
- 2) Keep coming up with more work to do until they are all working 40ish hours/week
- 3) do nothing, keep raking in whatever money you are and have everyone else be happy with the work load.
3 seems the smart choice to me.
If you don't know anything about networking it might be a bit daunting, but probably still within the realm of possibility given it's all gui based and the docs are detailed.
