comment OpenGL & GLSL 3.3 on an HD Graphics 4000 under Ubuntu 12.04
This doesn't seem to work quite yet in 14.04 (it is June now). glxinfo reports the same string for core profile but then: OpenGL version string: 3.0 Mesa 10.7.0-devel (git-f97166e 2015-06-01 trusty-oibaf-ppa) OpenGL shading language version string 1.30 And when I create a context with glut requesting version 3.3 I still get a version 3.0 context.

comment Random points inside a Polygon
@gabriel_littman. I believe you are correct. In the graphic for the equation there is a missing R(pi), which is present in the text... i.e. rotation by 180 degrees. I think that rotation matrix is [-1, 0; 0, -1] which is to say that we take the negative of its operand.
