Hello! I'm copying Lars and Eliot, who worked on this project during the summer, so maybe they can update everyone on the state of the project. Cheers, Carla.

Re: [Pharo-project] Pharo 2.0 on Raspberry Pi ?

by Sven Van Caekenberghe

I am making progress. It seems 1.4 does run out of the box, at least headless: pi@raspberrypi ~/Pharo-1.4 $ cat test.st FileStream stdout nextPutAll: 'Hello World, 42 factorial = '; print: 42 factorial; crlf; flush. Smalltalk quitPrimitive. pi@raspberrypi ~/Pharo-1.4 $ /usr/lib/squeak/4.4.7-2357/squeakvm -vm-display-null -vm-sound-null /home/pi/Pharo-1.4/Pharo-1.4.image /home/pi/Pharo-1.4/test.st Hello World, 42 factorial = 1405006117752879898543142606244511569936384000000000 No HTTP server like apache is installed by default, lucky Zn comes with Pharo then ;-) pi@raspberrypi ~/Pharo-1.4 $ cat zn.st ZnServer startDefaultOn: 1701. pi@raspberrypi ~/Pharo-1.4 $ /usr/lib/squeak/4.4.7-2357/squeakvm -vm-display-null -vm-sound-null /home/pi/Pharo-1.4/Pharo-1.4.image /home/pi/Pharo-1.4/zn.st And now visit http://localhost:1701 or (with avahi-daemon installed) http://raspberrypi.local:1701 from another machine, at first sight everything seems to work as expected. Things are a bit slow with the slower ARM CPU and a Stack VM, but that is normal. As for 2.0, there seems to be some startup problem: THERE_BE_DRAGONS_HERE ==== Startup Error: FileDoesNotExist: file:///usr/lib/squeak/4.4.7-2357 23 November 2012 5:33:13.051 pm VM: unix - armv7l - linux - THERE_BE_DRAGONS_HERE MessageNotUnderstood: receiver of "do:" is nil 23 November 2012 5:33:13.068 pm VM: unix - armv7l - linux - THERE_BE_DRAGONS_HERE MessageNotUnderstood: receiver of "do:" is nil 23 November 2012 5:33:13.089 pm VM: unix - armv7l - linux - THERE_BE_DRAGONS_HERE MessageNotUnderstood: receiver of "do:" is nil 23 November 2012 5:33:13.106 pm VM: unix - armv7l - linux - THERE_BE_DRAGONS_HERE MessageNotUnderstood: receiver of "do:" is nil 23 November 2012 5:33:13.123 pm Some code is referring to the VM directory and that seems to fail. Funny there is no better/usable stacktrace. I wonder whether FileSystem is completely supported on older VMs ?

Re: [Pharo-project] Athens Documentation (was: Helping with Athens development)

by StÃ©phane Ducasse

I think that having a proftef ilke approach is the way to go + class comments So creating a library of example like in mondrian or roassal is the best way to give a chance to people to learn. stef

Re: [Pharo-project] smalltalkhub and project ownership

by StÃ©phane Ducasse

Norbert I can tell you that I was exactly concerned about the same point and that we are talking about it since a couple of months. Nicolas implemented projects and privacy to support people wanted to do private business (yes we want to support it). Now he got stuck because of a problem in smalltalkhub and more important a bug in the cog vm. I do not know what is the status of this one. The idea is that soon (probably next week) a new version of smalltalkhub will get out.
