For working with a generic laptop that has entirely too much glare: If you can, sit in complete shade. Against the wall of a building with the sun on the other side of it for instance. Bright surroundings is almost as bad as being directly in the sun, it's still going to make the laptop screen seem to dim. Early morning/evening works best. If you can't get complete shade, wear black, sit at a 90 degree angle to the sun. Your goal is to minimize both light reflecting off of you onto the screen, and to minimize light hitting the screen/laptop.
