This post illustrates a interesting point about the language: Functions must take at least one argument In the data-driven world, namely MATH, there is no notion of a definition defining anything other than a translation of something into something else. Interesting.
Studying anything takes both discipline and perseverance. There is just no avoiding it. These are also the same skills you need to practice when you do those things. Work hard!
When you work on your exercises, you can leverage DrScheme to make it easier to find particular functions or bits of homework by using the definitions dropdown. I posted on it here: Here is how I implement exercises. I say implement, because I am concerned here with a coding detail, *not* design recipes. DrScheme has [...]

Overall it has been a pleasant experience working with Google Groups. Rather than set up a server, install the wiki, file share, and listserve myself, and host it on the Internet; I can set up a group there instead. It is pretty convenient. Additionally, their interface is pleasant and search works pretty well (no surprises [...]
Per Matthias, the best place to start HTDP is by quickly going through the prolog to the 2nd edition and then diving into the book. I posted on this here.
Q. Are we doing this to learn Scheme? A. No. As a result of working through the book, we will learn Scheme, but the goal is to learn how write programs, not learn Scheme the programming language. For that you should read http://www.scheme.com/tspl3/.
HTDP is FREE. Basically the only thing you need to take advantage of it is a computer, interest, and discipline. That is awesome!
While studying HTDP, there are a few opportunities that occur during the process: Practice Blogging: I am assuming two things: 1. We are all going to learn things. 2. It is going to be fun. That alone is worth blogging about. If you haven’t got a blog, this is an excuse to start one. The [...]
