Hello coding people. This forum is superb !
But let me adevrtise a quite unknown site about general amiga development:
gurumed.net
With this link, the url ends with ?GMLang=en . it set a cooky that direct you to the english side. The original site is french ( ?GMLang=fr to swap the cooky ) And the translation is going on. It is more about proper C coding on modern amiga and using the system the best possible, in a hardware abstracted manner.
But there is some article about PPC assembler, graphical code and cache tricks that can interest you !
Soon we will search people for an english redaction and make public announcement about 'the english side'. You can even open a new language side and translate articles :-). Fabulous isn't it ?
