Hi Oleg,
Thanks for your interest in GLASS. As Philippe said, GLASS is not quite
ready for general availability. Furthermore, as is typical in these
projects, docs (including tutorials) are likely to be minimal at first.
The people who will likely have the most success at first are those with
some background in GemStone, but we certainly want any Smalltalker to be
able to get up to speed quickly.
There isn't anything special about coming from Squeak, except that it is
easy since GS can load Monticello packages. You don't, however, have to
start in Squeak and use Monticello. In general, a Seaside application
should just be a Seaside application. One of the nice things about
Seaside is that it should not include any client UI code (where
Smalltalk dialects have traditionally been most different). The primary
challenge of coming from VW (or Dolphin!) is that GS does not have a
trivial way to load VW code.
You should not have to do much with collections. GS should implement the
ANSI spec for collections, so if you stay away from dialect-specific
extensions to the base classes you should be fine. As you get further
into scaling you application in GS, you may wish to switch some
collections over to "Reduced Conflict" collections (that better handle
multiple VMs changing a collection). This is a somewhat advanced topic
that Dale will probably cover in his blog
(
http://gemstonesoup.wordpress.com/).
If you want to run GLASS in the VMware appliance, you will need to be on
64-bit hardware that supports virtualization. Otherwise, you will need
to be on 64-bit Linux. Otherwise, keep an eye on
http://seaside.gemstone.com/ for more information.
