Re: [Pharo-users] Smalltalkers will, eventually, win. So says this old C++ programmer.

I think he forgets to mention Haskell, which is probably the reason behind the shift of Swift towards optional values (Option type in Scala, Maybe type in Haskell). You can't talk about modern type system without talking about Haskell, Monads and Algebraic Data Types (Maybe is a monad). I don't believe the future is dynamic typing, I believe it is type inference and optional typing. There is no need to be radical about it. One great sadly forgotten example of this is Strongtalk, which was rumored to be the fastest implementation of Smalltalk ever made (I don't know how it compares to the latest Pharo VM, though) and included an optional strong type system (http://www.strongtalk.org/) Strongtalk team was bought by Sun before they could release the language and their advancements in virtual machine development were taken by the Java Virtual Machine. It is one of my dreams to see Strongtalk back into action or maybe a version of Self with optional typing, but I unfortunately lack the required skills and time to do so. 2017-05-09 10:26 GMT-03:00 Ben Coman <btc(a)openinworld.com>: > Fantastic article.

Fantastic article. Very well rounded. I particularly liked "Meanwhile the Smalltalk programmers were scratching their heads wondering what the big deal was. You see, their language was also strongly typed; but their types were undeclared. In Smalltalk types were enforced at runtime." and..."You see, the Smalltalk programmers had solved the missile problem in their own unique way. They invented a discipline.

by ClÃ©ment Bera

Hi, At this address: http://files.pharo.org/vm/pharo/mac/ This VM: Pharo-VM-mac-latest.zip is for pre-Spur and should be compatible with Sierra. I don't know about the stable one as it's from 2014 and Sierra is from 2016 ... The VM suggested by Fabio should work, but I would not use a squeak VM for production with Pharo (some plugins are different / missing and it may be a problem in your use cases).

Hi, I have a demo image coming from a pre-Spur era, and I just realized that I cannot run the old VM on Sierra. Is there a version that I can use for this? Cheers, Doru -- www.tudorgirba.com www.feenk.com "It's not how it is, it is how we see it."
