The way to get this stuff started is to first make sure you can automatically provision whole boxes. There is some work done for this for a gemstone-seaside box: there are chef scripts, mostly by Willem and Norbert https://github.com/noha/virtual-gemstone The place to talk about this is this weekend at FOSDEM. There are devrooms focusing on these issues: Configuration Systems Management (Puppet & Chef), Testing and Automation (the Jenkins guys) Virtualisation on saturday and Cloud on sunday I'm not sure at what market heroku and appfog are aiming. They don't seem to have the right incentives to perform well, as they make more money if you need more instances. Might be perfect for hosting marketing campaigns or so, but definitely not for freemium based business models. DevOps on Hetzner servers might be a lot cheaper. Stephan

It would be a shame to lose the use of a Cog based VM. It is not that we need a 64 bit VM, but the 32 bit VM should be compilable against a 64 bit OS. This is beyond my skills... When I said that Heroku would be doable, I did not say it was the best way to go. All this looks still pretty complicated for people without *nix skills. Maybe it is worth the effort for what you get back, I just don't know. I myself like Amazon AWS a lot, but that is not PaaS, but IaaS with lots of options. Also note that there is no such thing as magic scalability... Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Hi guys I'm really interested in seeing this egg/chicken problem solved by getting something out the ground. for the visibility of Pharo and smalltalk in general. So I would love to see some proposals and some budgets to see how to Pharo association/ESUG/Consortium/other companies could put money on the table to get started.

The account also spammed on several other Smalltalk mailing lists.

look at PPExpressionParser class. it's designed for that and you have a great example in the class comment 2013/1/28 Hilaire Fernandes <hilaire.fernandes(a)gmail.com> > Hello > > I try to extent the example of the arithmetic evaluator[1], I don't > understand the magic underneath nor how you will make it works with > substraction. > > Changing method add to: > > add > ^ prod, ($+ asParser / $- asParser) trim, term > > > to parse mixture addition and substraction is wrong: > > parser parse: '1 - 2 + 6' -> #(1 $- #(2 $+ 6)) > > > The precedence is wrong. > > How will you make it work?
