Carried on arstechnica is an article on BeOS resurrected. As we know from previous discussions, BeOS was an open source Windows replacement. BeOS, as a project, was abandoned in 2001. Here is the link to Haiku: http://arstechnica.com/news.ars/post/20080212-first-look-haiku-poetically-resurrects-beos.html
Haiku currently has about 7 million lines of code written and is written in C++; networking is built into the kernel, rather than deployed in user space. Haiku employs source level FreeBSD network implementation; boots in only a few seconds; and is designed to be a desktop replacement.
What do you think.
