I have meanwhile Pharo 1.4 (squeak, etoys, scratch) and NBCog on my PC and an image which runs with squeak from http://www.preeminent.org/squeak/tut2007/html/ NBCog show too the Pharo-tower, question is it really Pharo? As a friend says NBCog is several times 'faster' then ..., reason for trying NBCog (too). Question, in NBCog, importing the Laser-Game code I get messages like Deprecated: Form subclass: #FormStub instanceVariableNames: 'locator' classVariableNames: '' poolDictionaries: '' category: 'Graphics-Display Objects''Deprecated14'
The 'fast' bit has nothing to do with NBCog but everything to do with Cog itself, yes this is confusing. The NB part is really advanved stuff currently under development.
Just download the One-Click for Pharo 1.4 and you'll get the fast Cog (i.e. JIT) VM for free.
Now, and this can be very confusing for beginners, Pharo Smalltalk is not the same thing as Squeak, it is evolving much faster, possibly at the cost of backward compatibility. Running older code on top of Pharo will not always work and possibly raise Deprecation warnings. In particular, etoys or scratch won't just work, even just discussing everything involved is above beginner level.
That being said, hundreds of externals packages do just work.
What is it that want to do ?
