Notes from Mark Reinhold's presentation at devoxx

I have always wanted to have generator in Java. After all, Python have this feature, Ruby and C#(*) too. A generator is a way to define an iterator but instead of implementing hasNext()/next(), you just implement a method (here generate) and use the keyword yield (or here a method yield) to send value that will be returned by next().

Sam at CodeOder.com asks a rather interesting question; asking which is much like opening a can of worms.

There are 8 alternative Ruby VM's and 4 of them will hit 1.0 status in the upcoming year. A detailed look at the past year and where the community is heading (hint: it's an exciting time to be a Rubyist).

Countless times I’ve heard the argument that you should use the var keyword with caution, that it decreases readability of your code, or how it can be misused.
