Congrats, I had twins about the same time you had rockhardawesome. I'm not going to lie. The first 6 months are going to suck. After that it's all sugarbeans and sodie-pop. Twins are great because other than the poop and food they practically take care of each other. (and they really do make up their own language) My advise for the first 6 months: 1) velcro swaddle blankets. 2) Lots of robo-swings. and most important 3) Keep them on the SAME SCHEDULE. If one easts then they both eat, when one sleeps, they both sleep. It's boot camp. Don't give in or you will never sleep EVER. Have fun

One thing to watch out for is to not stray too far into academic ground. The first comment said "many people don't know how to write simplest programs, such as "how to find the smallest common multiple of two integers"." I have been programming for over 10+ years and I have never needed to find the smallest common multiple of two integers....ever. I have also never needed to read or understand hex, so I would not expect anyone to know or care what comes after F. I'm positive there are a lot of great programmers who may not know these answers off the top of their heads because they are actually rather obscure (unless you were a math major maybe). Still, some things are truly universal the FizzBuzz test is pretty good. Some simple SQL is probably a good test also. I once had a Sr. developer who was just hired turn to me and ask "How do you do a 'outer' join?"
