I don't know how the OpenGL bindings to Go look exactly, but I can tell you at least this much:

The last parameter to glVertexAttribPointer should be the byte offset from the start of the buffer object, so (in your case) 0.

Note: The C type of that parameter generally should be int, as it's a byte offset. Instead, it's void* for legacy reasons - it used to have a different meaning before VBOs.

Instead of &f try passing either a literal 0 or, if this doesn't work, a pointer with value equal to 0. How to do that in Go? This is for you to figure out, since I don't grok Go. I told you what OpenGL expects and I hope this much helps.

Also: For debugging, please check glGetError() often.
