Just finished reading this gem from start to end. It is over 20 years old and it is crazy how it is still up to date and applicable. Great work.

I agree great book. Read it a long time ago.

@mclovinit there are some good open source Smalltalk implementations out there. Check out http://squeak.org and http://pharo.org if interested.

Any other recommend books or reads in this topic?

Agreed, still valid and worth reading!

@luife16 I would definitely recommend Clean Code by Robert C. Martin aka "uncle Bob"

@mokveldr I actually have that book. Just haven't gotten around reading it, school keeping me busy.

@luife16 I read it just after I followed a college course on design patterns. Those were a few months where so many pieces of the puzzle fell into the right place. Now reading The Clean Coder. And next up is the Pragmatic Programmer

Have my copy from '95 and still relevant.
