I agree that the situation in the article is complicated and that these homeless people were not exactly saints.
My point above is that these homeless people living in tents in an empty lot in January are worse off than the homeless people in the article that OP references. Those homeless people live in cars in a protected lot which I think is a big improvement from tent life.
I remember a 3D version of Tetris on an early IBM PC clone. Very early like 8088 or 286 PC. Don't remember the name and it was only wireframe and 1color (amber or greenscreen?) but I was very impressed with it. Seemed ahead of its time.
