Hopefully I'll get around to adding Objective-C support to PathScale's compiler some time this year, so we can have a single code path in the source for CPU and GPU versions, which seems more interesting than OpenCL, from a maintenance perspective. > Well, what I would interested in is a CoreImage framework implementation.

Banlu has been working on some of the building blocks for CoreAnimation, specifically on drawing views into textures and compositing them using OpenGL (he's going to work on animation later). CoreAnimation is most shiny when combined with CoreImage, since that lets you do all of the really shiny effects, so I'd love to see a CoreImage implementation. >> Can you suggest any components that I can help work on to better improve my >> Objective-C? > > You can contribute to GNUstep… For example, the new NSURL-related API added > with 10.6 are pretty useful and not available on GNUstep. NSString and > Foundation collection API lack some 10.5 or 10.6 methods too iirc. Yup, I added a few 10.6 methods to NSString, but there are quite a few useful ones. If you're working on Foundation stuff, it's worth looking at the ios docs, not the cocoa ones, since Apple tends to add newer stuff there initially. > Otherwise making progresses on SystemConfig would be nice, take a look here: > http://svn.gna.org/viewcvs/etoile/trunk/Etoile/Frameworks/SystemConfig/ > There is now DBusKit which can be used in SystemConfig to access DBus > interfaces.
