What we want is well designed and powerful libraries that enabled people. For the JVM question: it is a question of resources + the fact that jvm do not really support well some key smalltalk operations. Now I do not understand why people develop their own vm instead of joining forces. Doing in the long term something and finishing a task are the most difficult things.

Re: [Pharo-users] have a question for morphic Designer in pharo.

Don’t worry our korean is near to zero ;) > i want using "Morphic Designer" in pharo. > because pharo is smart smalltalk environment, and morphic designer is > useful(maybe only loook movie file) Yes it is nice. Now you should pay attention because once we looked at the events and it used a different event mechanism that used thisContext (too costly to be used for every morph events). Now I would be really interested to know if you succeed to make it work even partly. > but use not easy! because squeak and pharo is not same. > ok i can try. > > i make a this guide. > Morphic Designer in Pharo2-writeen korean. > http://workspace.onionmixer.net/mediawiki/index.php?title=Morphic_Designer_in_Pharo2 this is REALLY impressive! > now i can run in pharo. but encounterd error in playtime. > > look this section please. > http://workspace.onionmixer.net/mediawiki/index.php?title=Morphic_Designer_in_Pharo2#Step_06_::_.ED.94.84.EB.A1.9C.EA.B7.B8.EB.9E.A8_.EA.B5.AC.EB.8F.99.EC.84.B1.EA.B3.B5.21_.EA.B7.B8.EB.9F.AC.EB.82.98_.EC.95.84.EC.A7.81_.EB.81.9D.EB.82.98.EC.A7.80_.EC.95.8A.EC.95.98.EB.8B.A4._positionInWorld_.EB.A9.94.EC.84.9C.EB.93.9C > > > start drag item but rise debug error. > debugger display "positionInWord" is nil. > > > i misssion way for solution. > where look then can find way to answer? try to see in squeak how positionInWorld was implemented and see how to migrate it to Pharo. I do not know if the implementors of Morphic Designer is still maintaining it. May be he can help or else I suggest that you fork and publish your work. May be we were too aggressive about some methods that we removed. If you get some methods that you need for your project, let us know because we could add them into pharo or you can package them as extension of your project. let us know if you make progress. what could be good is if you put an image somewhere so that we can have a look.

Re: [Pharo-users] Stupid ideas when I'm bored:
this is brutally fun. :D and this got great success during the sprint last week. This is good to see that closing the window still works :) I was wondering why we get really big pixels at the beginning.

[Pharo-users] Geo coordinates operations
Has anybody implemented basic methods/classes to calculate distance between two points (lat, long) and similar operations? Regards, Esteban A. Maringolo
