And what about Seaside for example? Few years back, we used to have a Seaside + GlorpDBX + SqueakDBX example that we used for the university thesis. However, I guess it is quite outdated and note sure if it works. But maybe we should do that. I think it is a good idea. In addition, we can use the same example for the PBE chapter. Finally, I remember an ESUG project which idea was a open source application based in pharo, seaside, glorp, etc, to use as an example/learning. I don't remember the name right now....but it would be awesome if that app could be changed to use GlorpDBX + SqueakDBX instead :) thanks mariano > ----- Original Message ----- > *From:* Mariano Martinez Peck <marianopeck(a)gmail.com> > *To:* GermÃ¡n Arduino <garduino(a)gmail.com> > *Cc:* ESUG Mailing list <esug-list(a)lists.esug.org> ; A friendly place > where any question about pharo is welcome<pharo-users(a)lists.gforge.inria.fr>; Pharo > Development <pharo-project(a)lists.gforge.inria.fr> ; The general-purpose > Squeak developers list <squeak-dev(a)lists.squeakfoundation.org> > *Sent:* Friday, March 04, 2011 7:53 AM > *Subject:* Re: [Esug-list] [squeak-dev] [ANN] ESUG supports once > againSqueakDBX > > > > On Fri, Mar 4, 2011 at 11:50 AM, GermÃ¡n Arduino <garduino(a)gmail.com>wrote: > >> Certainly all the Smalltalk community should thank ESUG by the >> continous support to lot of initiatives. >> >> > And to ESUG sponsors :) > and ESUG conference attendees...and...and..lots of people :) > > >> Thanks ESUG. >> >> >> 2011/3/4 Mariano Martinez Peck <marianopeck(a)gmail.com>: >> > We are really happy to announce that ESUG will sponsor us once again >> through >> > the ESUG Summer Talk project.

Stephen Elop (of Nokia) allegedly wrote "In 2008, Appleâs market share in the $300+ price range was 25 percent; by 2010 it escalated to 61 percent. They are enjoying a tremendous growth trajectory with a 78 percent earnings growth year over year in Q4 2010." That means there can be large numbers of Android devices on the market, but at a very low price. That's killing the producers, instead of making them rich. Or to explain it differently: Apple's problem is getting enough devices out the door. Not the price. If they want more market share, they can simply introduce lower-priced models, unlike the Android producers. As long as the Android market is so shattered and so incapable of producing compelling alternatives, they wait. Do you know "Inside the Tornado" by Geoffrey A. Moore (you might know him from "Crossing the Chasm"). My version has a quote by the founder and CEO, NeXT Computer on the title page. Stephan

Hi, GÃ¶ran Krampe wrote: ...or we need to get Squeak running inside/on-top-of Dalvik somehow. Weird ideas: - PotatoSqueak is a port of the Squeak VM to java. Run that on Dalvik and hey... - PySqueak using Pypy could probably generate a fast Squeak VM running in java bytecode which possibly also could be run on Dalvik. ------------------------------------------------------------------------------------------------------------------------- Well the original discussion on the Squeak ML declined into the OLPC issues (back to Intel that is ;) Let's continue here. Thanks for the hints, I looked into these projects, but: Potato Squeak (JSqueak) doesn't seem alive. I tried to run it on my PC with some recent Java (don't remember which version, same as I use to compile Android stuff). Very slow, crashed all the time. Plus image version is 2.x ... PySqueak seems like the repo is gone. Also, it's old too. Anyway, wrt translation of Squeak/Pharo VM to Java. How much labor would it take to change VMMaker so it generates Java code instead of C? Given some similarity between the two languages syntax? I need to move on with the native port because my endpoint is in a concrete application rather than the port itself. But would anyone be interested in adjusting VMMaker? Thanks. -- Dimitry Golubovsky Anywhere on the Web
