Hi ronie This is super cool. I would prefer Volcano to Pompeii because lot of people died at pompeii but it the dead in Pharo are the old Morphs this is ok for me :) About the back end, this is really good to have multiple back-ends for Bloc.

Hi Ronie, This is fascinating work! We will definitely look at this to see what it would take to have it as a Bloc backend. And thanks a lot for tackling the SDL2/OSWindow issue. We will test that as well.

[ANN] Pompeii Volcanic Graphics, a mesh based 2D graphics API

by Ronie Salgado

Hello, I am releasing a first version of a new 2D graphics API that I am making for Pharo, using OpenGL. [image: ImÃ¡genes integradas 1] [image: ImÃ¡genes integradas 2] http://smalltalkhub.com/#!/~ronsaldo/PompeiiGraphics https://youtu.be/emE6_1RpAo8 This 2D graphics API is not vectorial based becase it does not use SVG style paths. This API is triangle mesh based, so it is more friendlier with the GPU than Athens or Sparta. With this API I did a basic gui toolkit, with only two widgets: buttons and label. I did this Widget toolkit to not mess with Bloc, and because I need something relatively stable for the Woden 2 level editor. For now, I am leaving this widget toolkit mostly as a demo. Hopefully it is possible to make Bloc backend using this API. During the process of making this API, I had to fix several bugs with OSWindow, and bugs in the interaction between OSWindow and OpenGL. The biggest problem was a race condition between the creation of an OSWindow using SDL2, and the events (such as Expose) that are sent to the just created Window. As for Mac OS X, OSWindow is out of service until a pull request ( https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/138 ) gets integrated into the VM. Best regards, Ronie

Git breaks Monticello's version numbers

by Oleksandr Zaytsev

Hello Two days ago I was trying to send the slice with my fix to PolyMath using Monticello. But the version number got set to 1494471195. Today I realized that all the packages to which I commit are numbered like that. Cyril Ferlicot explained to me that this happens when I mix git and Monticello commits. He suggested that I use a separate image for committing to GitHub, or file out/file in if there is a lot of changes to commit. Can this be considered a bug? Should I report it? I think it would be causing problems for many people. Oleks
