Re: [Pharo-dev] Thanks to all of you who asked

I was pleasantly surprised that you had not loads of casualties with such a big earthquake. And I was also wondering how many people are from Chile in this mailing list. As a Greek I have plenty of experience with quakes though none as big as that one. Should have been quite a shaking. I guess even earth has the need to dance from time to time :D On Thu, Apr 3, 2014 at 11:44 AM, phil(a)highoctane.be <phil(a)highoctane.be>wrote: > Crossed my mind: create some visualizations using Roassal about the > quake(s) in Chile and advertise your local biz presence. #datajournalism, > This can turn big. > Le 3 avr. 2014 10:22, "Sean P.

strange creation time

by Tudor Girba

Hi, I just stumbled across a strange piece of code, and I am wondering about the reasons behind it: FileSystemStore>>creationTime: aPath self nodeAt: aPath ifPresent: [ :entry | ^ self basicCreationTime: entry ] ifAbsent: [ ^ false ]. In what case does returning "false" make sense? Doru -- www.tudorgirba.com "Every thing has its own flow"

Crossed my mind: create some visualizations using Roassal about the quake(s) in Chile and advertise your local biz presence. #datajournalism, This can turn big. Le 3 avr. 2014 10:22, "Sean P.

Re: [Pharo-dev] [Moose-dev] Re: Re: Re: Fwd: Font problem is still there

by J.F. Rick

Cool. I just loaded the latest NB and Athens (as Igor sent around) but my image is not fully up to date. I'll try downloading a new one and reloading my work from packages. I just wanted to make sure that this was worth the effort. If that doesn't work, then I'll send Igor my image.
