Good resources for learning how to write shaders, Cg, ShaderLab?

It's already on the list, the 3rd link from the top ;>

Thanks for catching my mistake Robert. . . Long week :)

It's a pity I'm not that good at catching my own mistakes ;>

your first link does not actually go to the $$anonymous$$anual, but to the Reference.
Unless I overlooked something, you don't have the link to the Shader-$$anonymous$$anual
(maybe you could mark your answer as community-wiki?) Greetz, $$anonymous$$y.

is the shader talk from Unite 2008 still relevant with the new Shader Lab and mobile shaders?
