Ah thats great news Esteban, 70% to 9% is more than enough for my needs. I can wait a year, no problemo. This is all optimised inside VM ? Or you plan to bring those optimizations also inside the image ? SDL2 is a very powerful lib and a very wise move to move to it. Not just for 2d graphics, but also 3d, events and so much more.

Super! Can't wait to have SDL drawn thingies :-) I have it loaded on a 3.0 on Windows 8.1 and some examples give me the red crossed square.

Fwd: Re: Example implementation of associations with Slots in Pharo 4.0

by stepharo

The problem is that a relation may be one to one, one to many, many to one or many to many. In each name, the first word refers to upper source multiplicity and the last word to the upper target multiplicity. So according to me RelatedToOne has not the same meaning than OneRelatedTo or ToMany. I am not sure that you want to describe the source multiplicity, so ToOne and ToMany seem more adapted. In Java persistance is specified with the @OneToOne, @OneToMany, @ManyToOne and @ManyToMany annotations.

by kilon alios

very good example and very informative thank you. Sadly it also shows that even with Athens Pharo is incredible slow. Simple animation spiking a single 3.2 Ghz core to 50% does not look very promising for heavy big size graphic based animations. Which is not a surprise since this was also evident the first time I tried the VGTiger demo.
