I am very excited for such a project. I hope you manage to fix the stdout problem on macos.
One thing I would like to see is an expansion of the ability of OSProcess to launch multiple instances of pharo and make them communicate with each other. Thats a way to have pharo running on multiple cores. Maybe establish a framework of communication of images that will be based on the existing design of the fork mechanism in Pharo. Python is doing something similar with multiprocessing module which launches multiple processes of cpython executable and makes them communication with each other through a similar api to its threading module. This way python takes advantage of multiple cores. Python threads like pharo are green threads and pharo like python has a GIL like mechanism. Taking into account that current computers have at least 4 cores, its not a bad idea to speed up pharo like this at least 400% ;) On Sat, Dec 19, 2015 at 3:24 PM Mariano Martinez Peck <marianop...@gmail.com> wrote: > Dear all, > > I am tremendously happy to announce you that Pharo Consortium will sponsor > yet another development effort.
