The male Chinese speakers had THICK American accents. Nothing really wrong with the language, but think the stereotype German speaking English. That was kind of strange to me.
In 2003 I installed a scale in our dorm toilet. When you sat down you push a button and when done you push it again. If you were in the top five you could enter your (three letter max) name using a two button system. Top five were displayed using a super low resolution screen similar to a pinball high score screen.
The three books I recommend are these: {0,1,2}. The first two are best read together and maybe sprinkle in a bit of [2]. If you are on Linux or Mac then the last one obviously has to be substituted for something else.
