Hi, I'm currently working on a chapter about Sockets for the Pharo by example book. I'm half way, though there is more material than what is on the pharo collabor-active book. It's a pitty, that pharo by example and the collaborative book aren't linked.
Any way, I'll be happy ot send what I have written to anyone who request it. Noury On 29 août 2010, at 23:05, Sean P.
