OSPlatform currentVersion

by Norbert Hartl

Does anyone know when the output for OSPlatform currentVersion changed? In Pharo 4 I get '1095' and in pharo6 I get '10.12.5'. The determination if it is a OSX system or older is done by currentVersion asNumber >= 1000 which changes behaviour because the currentVersion string has been changed. Is the output the one supposed to be? Norbert

Re: [Pharo-dev] Simply Happy

by Dimitris Chloupis

Pharo is finally in a mature state. I would not recommend Pharo few years back because of severe lack of documentation and libraries and several other issues.I would definetly recommend it now to people who want to try something fresh and well designed. Documentation is in much better state, new libraries pop up like mushroom old ones have matured to very stable , reliable and flexible. I dont have hopes that Pharo will be in the top 10 of popular languages but entering the top 100 is definetly not far away if we are not already there. 99.9% of programming languages never ever come close to that. On the other hand I dont want Pharo to become too popular because popularity comes usually with the price of huge compromises. So we are definetly close to what I call "the sweet spot". Glad to be part of the family, keep the great work going and well done :) On Thu, Jul 6, 2017 at 12:22 PM Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > +42 > > > On 6 Jul 2017, at 10:58, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > > > +100 > > > > Doru > > > > > >> On Jul 6, 2017, at 10:57 AM, Stephane Ducasse <stepharo.self(a)gmail.com> > wrote: > >> > >> Hi pharoing people > >> > >> Just a little word to tell you that I'm super happy about the future of > Pharo. > >> The consortium is growing and will probably be able to pay esteban and > clement. > >> The roadmap for Pharo 70 is really exciting. > >> The bootstrap, git and the new project in the pipe will boost us. > >> So I wanted to thanks you all for all this super great energy. > >> > >> We (you and us) are building a super cool future. > >> > >> Stef > >> > > > > -- > > www.tudorgirba.com > > www.feenk.com > > > > "Every successful trip needs a suitable vehicle." > > > > > > > > > > > > > > >

Yeah, it is truly great! I think we've crossed a border. In the past a lot of our legacy was compensating the awesomeness. In the meantime I have the feeling that the awesomeness sticks out much more clear. Thank you all for making this community!

Simply Happy

by Stephane Ducasse

Hi pharoing people Just a little word to tell you that I'm super happy about the future of Pharo. The consortium is growing and will probably be able to pay esteban and clement. The roadmap for Pharo 70 is really exciting. The bootstrap, git and the new project in the pipe will boost us. So I wanted to thanks you all for all this super great energy. We (you and us) are building a super cool future. Stef
