As a professional programmer, I naturally have a keen affinity for various computer models including those that we put in our pockets.
However as a father of two, I firmly believe that computerised or televised entertainment is harmful to childrens development, and must be restricted as much as possible during formative years.
Its much too easy leave it to barney the baby-sitter to entertain the children.
I have seen how children get mesmerised my the screens and stop interacting with the rest of their under-developed senses.
So for now let him copy your behavior with preferably a wooden non-toxic imitation.
Let him develop the skills and senses that you can now take for granted.
At 18 months he's barely mastered the tactile sense, and should be experimenting with surfaces of different textures, especially with his mouth.
In years to come when the basic skills and senses are developed, he can start attaining specialised computer skills if so desired.
Baby-hacker might be a cute idea, but seeing as so many adult hackers have imbalanced development, typically below average in either social or physical development, try to lead the kid towards a balanced development.

@jellomizer, As a good developer, the braces in your sig should be correctly balanced DoItFaster(DoWhatIWant() ... DoItFaster(DoWhatIWant()) Could that be indicative of why developers shouldn't have production access?

I think its a variation of asshat.

I would say that the future popularity of the JVM is pretty secure with groovy, jruby, scala and the myriad of other languages that are now available on the JVM, see wikipedia List_of_JVM_languages.

There is a huge advantage to java programmers by staying within the familiar JVM world when changing a language rather than jumping to a completely new and foreign environment - familiar stacktraces, reusable libraries etc.

The "primary" language on the JVM - java will inevitably evolve slower (JCP = design by committee) and will therefore struggle to remain at the cutting edge.

So Mrs. Frog did the earth move for you ....

Have a look at the tests on BlackBeltFactory http://www.blackbeltfactory.com/Home.wwa These tests cover some of the most commonly used frameworks and tools within the wider java environment. Also learning design patterns is going to be indispensable and SQL is a must.
