The Elements of Computing Systems: Building a Modern Computer from First Principles

I really enjoyed "Land of Lisp".

I don't code in Lisp for work, nor do I prefer it as a language, but it has some really deep ideas that are useful regardless of what you build and what tools you use.

Found Kernighan and Plauger's Elements of Programming Style useful - interesting to see how many of their comments on Fortran and PL/I code still remain very valid problems.

Their further book Software Tools in Pascal I found inspiring (along with SICP) as they show how you can build very powerful and useful tools from small modules slotted together - SICP showed me this in the extreme with chapter 2 ending with an implementation of a full numeric tower

I would bet on "structure and interpretation of computer programs".

Oh and "The Art of Computer Programming" series by Donald Knuth
