[Pharo-project] Pharo on VIA mini motherboard
by Olivier Auverlot May 23, 2012

May 23, 2012

Hi, it will be cool to have Pharo on this type of ARM motherboard ;-) http://liliputing.com/2012/05/via-apc-a-49-android-computer-with-an-arm11-c… The hardware seems to be close of the Raspberry card but the connectic is more rich. Olivier www.auverlot.fr

[Pharo-project] Fwd: Re: [Sugar-devel] Dr.Geo on XO 1
by Hilaire Fernandes May 23, 2012

May 23, 2012

With Pharo 1.4 (but not with Pharo 1.3) we have a problem leading to the crash of DrGeo (based on Pharo 1.4) on low memory machine. It is clearly a problem related to Pharo 1.4 Any idea why ?

I actually had used "-march=pentiumpro -mtune=geode" as recommended here: http://wiki.laptop.org/go/Geode_LX and even with an additional -O0 it still crashes. > In gdb I see it's segfaulting inside the GC logic.

YES! That reproduces the crash on XO-1.5. Good thinking! :) I could also reproduce it in a virtual Ubuntu 12 with 768 MB RAM (!) but no swap. Top reports: Mem: 766204k total, 601588k used, 164616k free, 45624k buffers Swap: 0k total, 0k used, 0k free, 277024k cached but DrGeo still crashes. OTOH, Etoys runs fine using the same Squeak VM on the same system (and on XO-1). So I wonder what the new DrGeo does differently ... - Bert -

Ok. 20.00 I'll be at the front of the main entrance of Lille Flanders. Stephan

[Pharo-project] Morpheas , bringing Morphic to Opengl (3d GUIs)
by dimitris chloupis May 22, 2012

May 22, 2012

I have started my first project with Pharo (and hopefully Squeak too) called "Ephestos" .Â http://www.squeaksource.com/ephestos.html Ephestos is divided into 3 areas/ elements / concepts : a) Morpheas b) Proteas c) Orpheas Morpheas is an effort to bring Morphic to OpenGL and to implement 3d guis , that can be designed in blender ( probably will implement a addon exporter too from blender to Pharo) and deployed in Pharo , minimising coding and maximising ease of use, since a 3d gui can be fairly complex to program.Â The reason why I am posting here is for your help. I am very new to Pharo and smalltalk and Ephestos is an extremely ambitious project which I hope to be commited for at least the next 5-6 years which I plan to release version 1.Â My first rule is of course , because the project is already very ambitious, "code reuse". I want to be informed what efforts there have been towards that direction .Â Mr Stef published recently a great PDF document Â titled "Pharo's Vision : Goals , Processes and Development effort" in it there is the following quote about Morphic "What have been done so far. Igor Stasenko did the following: â¢ Designed and implemented a new canvas API and all the necessary abstractions to generate adequate code for different backends. â¢ Deep integration to be able to inject frames into existing VMstructure (Igor can you confirmthis?) â¢ Designed and implemented a new textMorph, paragraph and other classes. â¢ Defined a default back-end. â¢ Defined a Cairo back-end. â¢ Defined an openGL back-end (using an OpenGL calling framework).Â " So I guess my question should be directed towards Igor, but maybe someone else also works in this. I am interested in any information about Morphic and OpenGL . I am also interested even on partial support of graphics engine like Irrlicht , Ogre and Open Cobalt. My main focuse is Nativeboost cause it appear to have a new enhance FFI, and of course the possibility of inline Assembly code. Â Has anyone , advice , suggestions , ideas and hopefully some documentation I can use Â ?Â I am already studying both OpenGL and Nativeboost / NBOpenGL .Â

I've checked my train ticket. I'll arrive at train station Lille-Europe at 19.52. I assume it has an info-point or so? Stephan
