13 The queens program solves the n-queens problem (where, in this program,
14 N is between 5 and 10 queens) using a straightforward backtracking
15 algorithm. The problem is: how may one place N queens on an NxN chess‐
16 board such that no queen can attack a sister?

45 It's not unknown for this and other OpenGL hacks to fail under hardware
46 accelaration (UtahGLX) and take the X server with them. Texture images
47 must be 16x16 or 32x32 or 64x64 etc.
