Everyone goes free! Major operating systems vendors are releasing
their systems for free. Free does of course mean different things
here. When BeOS says free (www.be.com/products/freebeos) then that means free of charge. For the Realtime Operating System QNX free is more than free of charge. Their OS is now
open source (www.qnx.com/news/pr/apr24_00-openpl.html). At Sun Microsystems it was since
some time already possible to get a copy free of charge (solaris 7 for free)
they will continue that and make also the source code for solaris 8
available (see www.sun.com/developers/tools/solaris). Apple seems also to have plans
to open "a very small" part of its code (see e.g
Darwin Open Source SDK).
Is this a new way of "selling" software? .... or is it
just a fashion? Are these firms really hoping to improve their code
by making it available to the public or is it a means to get new customers?
In any case this new "free" is certainly a
result of the growing importance of Linux.
