This is a very good book. I still have my copy. Stanford used it for intro CS theory classes. It's great that it's available for free now.

Realistically, this represents all the CS theoretical knowledge required for 99% practicing developers. At Acunote we occasionally need remedial training materials for new hires, say on complexity theory, and a chapter from this book will work great.

Good to know. I was just about to ask if it was any good.

Thanks.

For those who don't know, Aho and Ullman wrote the "dragon book", a classic text on compilers.

Aho is also the "a" in awk.

brilliant, didn't know that! (and I do know who w and k are in awk fame!)

Makes me want an iPad to read it on.

I'm still absolutely blown away by the fact that the iPad doesn't have a reader which allows you to annotate books as you read them!

Thank you for posting this.

section 8.7 deals with relational algebra. this is a really nice mathematical underpinning to SQL.

It would be great to have it as a single pdf (or better yet, epub).

Anyone got the right tools to make it so quickly?
