[ANN] Pharo VM packaging for Ubuntu

by Damien Cassou

Hi, I'm happy to announce a brand new packaging of the Pharo VM. The packaging works with all officially supported Ubuntu releases, both 32 and 64bits (see this list of Ubuntu support dates: http://en.wikipedia.org/wiki/Ubuntu_%28operating_system%29#Releases) I pushed these new packages to a different PPA so I can test without impacting current users : https://launchpad.net/~pharo/+archive/unstable/+packages If you are using an old version of Ubuntu (e.g., Precise 12.04 or even Lucid 10.04), you should try with this new PPA. Please report problems by email to me directly. An advantage of this new packaging is that it should become much easier to create Ubuntu packages for your own Pharo projects. I will talk about that later as I try these new packaging mechanism on the Launcher, Pillar and Phratch projects. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Re: [Pharo-users] 3D with Pharo and OpenGL ?

by Jean Baptiste Arnaud

there are also my crappy tools that I develop to understand the wavefront format: http://smalltalkhub.com/#!/~jeanbaptistearnaud/ObjModel/source It is able to load .obj file generated from blender and integrate some material. It is really raw but it is with this tool that I import the Xwing model and beginning to debug material. http://jeanbaptiste-arnaud.eu/opengl/ On 22 May 2014, at 18:10, kilon alios <kilon.alios(a)gmail.com> wrote: > you can find plenty of code in Roassal3d that I think uses the NBOpenGL library here > > http://www.smalltalkhub.com/#!/~ronsaldo/roassal3d > > NBOpenGL is basically a wrapper for OpenGL with Nativeboost.

[ESUG 2014] Student Volunteer Program - Cambridge, England 18-22 August

by Damien Cassou

Student Volunteer Program ------------------------------------------------------------------------ If you are a student wanting to attend ESUG at Cambridge this summer, have you considered being a student volunteer? Student volunteers help keep the conference running smoothly; in return, they have free accommodations, while still having time to enjoy the conference.
