I remember The Unix Programming Environment by Kernighan and Pike as an excellent introduction to Unix shells and general Unix programming. IIRC, throughout the chapters, it has you build some kind of interactive command line music organizer, which really demonstrates how much you can get done with a few simple shell scripts.

Here's the slightly modified answer I just posted there (even though it's an old question):

Back when he was still doing podcasts Joel Spolsky answered the similar question, which was partly "Does a good programmer without a CS degree really have a chance to get a job at Fogcreek?[1]" (It's near the end of the page.)

He says that for a good self-taught programmer who began with a high-level language, say PHP or Java, who comes at programming from a practical perspective, there are a few important parts of the CS curriculum the person may have missed out on, and goes on to list some books that would help fill in those gaps.

Off the top of his head he named these books in about this order:

- Structure and Interpretation of Computer Programs[2] (also free online[3])

- C Programming Language[4]

- The Unix Programming Environment[5]

- Introduction to Algorithms[6]

He said that those books covered the aspects of the CS curriculum his company needs in a good programmer, e.g. being able to create algorithms for an uncommon data structure.

Those books all have the added advantage of having exercises, and all being a very pleasant read. SICP is an introduction to many of the big ideas in CS: data structures, streams, recursion, interpretation, compilation, register machines, etc., and their implementation in Scheme (a kind of Lisp). It's a great place to start. The next two focus on implementation details like pointers and memory allocation. They are compact, powerful books. The last, Introduction to Algorithms, seems misleadingly titled, as it is fairly comprehensive and used in both undergraduate and graduate courses. If you work your way through the entire book, chapeau!

It is actively harmful to teach students that software architecture is something that somehow arises from diagrams or that those kinds of silly pictures capture anything important about it. Powerful architectures come out of powerful ideas that in turn come from accumulated hard work of many people in different disciplines. One can learn much more from walking through the actual source code of some classic projects and from trying to understand the ideas that make them tick:

https://github.com/onetrueawk/awk - UNIX philosophy of small tools, DSLs, CS theory: state machines / regular expressions, Thompson algorithm ...

https://github.com/mirrors/emacs - Both a program and a VM for a programming language, hooks, before/after/around advices, modes, asynchronous processing with callbacks, ... Worth to think of challenges of designing interactive programs for extensibility.

https://github.com/rails/rails - Metaprogramming DSLs for creating powerful libraries, again a lesson in hooks (before_save etc.), advices (around_filter etc.), ...

https://github.com/git/git - The distributed paradigm, lots of CS theory again: hashing for ensuring consistency, DAGs everywhere, ... By the way, the sentence "yet the underlying git magic sometimes resulted in frustration with the students" is hilarious in the context of a "software architecture" course.

One of computer algebra systems - the idea of a http://en.wikipedia.org/wiki/Canonical_form

One of computer graphics engines - Linear algebra

...

There are loads of things one can learn from those projects by studying the source in some depth, but I can't think of any valuable things one could learn by just drawing pictures of the modules and connecting them with arrows. There are also several great books that explore real software design issues and not that kind of pretentious BS, they all come from acknowledged all-time master software "architects", yet all of them almost never find diagrams or "viewpoints" useful for saying the things they want to say, and they all walk you through real issues in real programs:

http://www.amazon.com/Paradigms-Artificial-Intelligence-Prog...

http://www.amazon.com/Structure-Interpretation-Computer-Prog...

http://www.amazon.com/Unix-Programming-Environment-Prentice-...

http://www.amazon.com/Programming-Environment-Addison-Wesley...

To me, the kind of approach pictured in the post, seems like copying methods from electrical or civil engineering to appear more "serious", without giving due consideration to whether they really are helpful for anything for real-world software engineering or not. The "software engineering" class which taught those kind of diagram-drawing was about the only university class I did not ever get any use from, in fact I had enough industry experience by the point I took it that it just looked silly.

If you consider C to be language-agnostic, here are some gems. These are personal favorites as much for their excellent writing as for their content.

The Unix Programming Environment was published in 1984. I read it over 20 years later and was astonished at how well it had aged. For a technical book from the 80's, it is amazingly lucid and well-written. It pre-dates modern unix, so things have changed but much that goes unstated in newer books (for brevity) is explicit in UPE. (Plus, the history itself is illuminating.) It gave me a much deeper understanding of how programs actually run over computer hardware. Examples in C are old-school and take a bit of close reading but oh so rewarding. https://www.amazon.com/Unix-Programming-Environment-Prentice...

Mastering Algorithms in C. Another fantastically well-written book that shows (with practical examples) how to implement common algorithms. This is just such a great book! https://www.amazon.com/Mastering-Algorithms-Techniques-Sorti...

Also:

Code (Petzold). This one is truly language-agnostic. Others have mentioned it already. Can't recommend enough if you're iffy on the internals of computers and programming. https://www.amazon.com/Code-Language-Computer-Hardware-Softw...

Write Great Code (Volumes I and II). Randall Hyde's books are fantastic explications of the underlying computer operations. Examples are in assembly or pseudo-code but easy to understand. https://www.amazon.com/Write-Great-Code-Understanding-Machin...
