Most of the lessons have been moved over to the new site - is there a particular one you are looking for?

if you look at Geometry Spreadsheet of any geo, go to Prim or Detail, both of them have Intrinsics menu
in that menu you can see what intrinsic data you can access
each primitive data may have its own set of intrinsics so you will not always see all, but all that apply to your primitives

most of them are selfexplanatory
use primintrinsic() or detailintrinsic() to get them or setprimintrinsic() to set
not all intrinsics can be set, only the ones with not greyed out values in spreadsheet

Click on the gear in the node and there set the parameter as “Save as Permanent Defaults”.

Moin,

to extend what Arthur already explained:

VOPpoint pcP= v@P;

creates a 3-parted-vector named pcP and assigns to it the current position (“current” meaning that the VEX code most likely is getting iterated over all positions available in the specific geometry context, be it points, vertices or primitives, depending on the node connection it has).

The “@” means that the “P” (the “P” after the “@” stands for “current position”) is a globally accessible variable, in Houdini speak you would pronounce it “attribute position” (@ for attribute, P for position).
The “v” before the “@” is a type-cast, it is to make sure that “pcP” gets a 3-component vector value (in the case of “P” that should be reliably so, but always putting the type before the variable seems to me like a good habit).
