For an exceedingly well written intro to crypto I'd recommend The Code Book: The Secret History of Codes and Code-breaking by Simon Singh

When I got around to a final year security comp sci module it turned out that most of the information had been covered in The code book.

• Better Explained for math
• Explained Visually for math/CS
• /r/AskScience
• /r/AskHistorians
• Explain Like I'm Five (only sometimes good)

I always recommend Flatland to anyone interested in visualizing extra dimensions.

And you should also have mentioned Best Textbooks on every Subject.

I tried this earlier, with Great Explanations.

If you are often travelling over bridge by car, having a car-knife could be handy in case you go over. The device generally comes equipped with a seat belt cutter, pressurized hammer, and flashlight.

Some policy issues affected by media in democratic countries: Daniel Komo argues that people hear about trade policy (I imagine this is extensible to other kinds of policy) largely because oppositions have incentive to attack government trade initiatives. But because propagating information is expensive, often opponents will focus attacks on simpler, easier to explain policy decisions, rather then ones that are more complex, since efficient use of space is cheap. He concludes that democratic political competition may lead to what I might call a kind of "reverse" conjunction fallacy: simpler policy decision tend to get more prime-time, coverage, and critism than more complex decisions.

• I would heartily recommend Project Euler for Haskell and to anyone picking up a new language (or programming for the first time).
• For Haskell specific problems, there is 99 Haskell problems.
• For building monad intuition, there's a tutorial with some problems here.
• This is a tutorial where you implement a Scheme in Haskell.
• Programming Praxis has a bunch of practice exercises.
• I haven't tried this project out, but it's supposed to allow you to work on TopCoder problems with Haskell.
• There is a Haskell course with problems being put together here. I'm sure how it works, though, and documentation is sparse.
• There's more advice here.
• If you're looking for Haskell code to read, I would start with this simplified version of the Prelude.

Why are you committed to that book? SICP is well-tested introductory textbook with extensive exercises. Added: I meant to say that it is functional.
