I would like to take it a step further and ask a question that has been bothering me a while. On my time in the academy I studied the following two books (regarding C):

[1] Advanced Programming in the UNIX Environment https://www.amazon.com/Advanced-Programming-UNIX-Environment...

[2] C Programming Language https://www.amazon.com/Programming-Language-2nd-Brian-Kernig...

In combination with other classes (and books) on networking, operation systems, data structures we covered a big variance of use cases with C. My question is: How do I take this to the next level? For example I feel I never missed a concept from those classes but when I see C code posted on a thread here it's probably something completely unreadable and complex. Can anyone provide resources to advance a little? What should I study if my goal is to make good and useful modern C software?

I feel like my typing is a bit abstract but I will be happy to clarify.

PS Yes, I've heard of C++ and Rust ;P

neat. Great way to explore the systems.

For me out of university, it was a co-workers books (some of which I ended up buying) that help me understand the role of UNIX better (I used the alpha machines at university, but was thrown into HPUX/Solaris at work..)

I think this was one: https://www.amazon.com/Advanced-Programming-UNIX-Environment...

Of course a little out of date now, but a lot of the general concepts are the same.

Unix Power Tools helped me a lot as well. https://www.oreilly.com/library/view/unix-power-tools/059600...

How did others learn this stuff?

Unix System Programming. A course largely based around https://www.amazon.com/Advanced-Programming-UNIX-Environment...

An interesting side-effect of this course - I got _really_ good at using a console/command prompt and handling text with vim and pipes and filters and other text manipulation. I think this has helped me me productive at my jobs way more than I thought it would :)

I used the first edition, but I think all you need is this:

https://www.amazon.com/Advanced-Programming-UNIX-Environment...

If you want to become a professional and not just a dabbler I would recommend reading some of the following books I have in my bookshelf:

[0] RHCSA & RHCE Training and Exam Preparation Guide by Asghar Ghori. This book will help insure you know your stuff as your system engineer/administrator wise.

[1] A Practical Guide to Linux Commands, Editor and Shell Programming Third Edition. This book will cover the majority of what you would need and want to know when connecting to a remote linux system over ssh.

If you want to get under the hood and become an expert, the following books should help get you started:

[2] Advanced Programming in the UNIX Environment

[3] The Linux Programming Interface: A Linux and UNIX System Programming Handbook

[4] Linux Kernel Development 3rd Edition

To get a nice general overview and get up and going quickly:

[5] How Linux works: What every superuser should know

[6] The Linux Command Line

[7] Python Crash Course

[8] Automate the boring stuff with Python. This is a great book to help you think about how to automate most of the repetitive things you will end up doing on a regular basis.

Its a bit tricky I think.

> A secure coding standard form CERT should focus entirely on describing conventions and program properties that do not already follow from the standard as a matter of correctness.

from CERT 1.7 "The wiki also contains two platform-specific annexes at the time of this writing; one annex for POSIX and one for Windows. These annexes have been omitted from this standard because they are not part of the core standard."

So while the CERT does use some examples from system interfaces its not a standard for programming the system interfaces for POSIX or Windows. It looks like there trying to limit the standard to ISO C. The examples you gave fall into the system interface category. POSIX is huge and the same for Windows, much bigger then ISO C.

I think in order to explain conventions for a system interface you really need a longer form publication like a book. So you can take 50 pages to describe an interface and how to use it and show examples etc.

The best way that I have found to figure this stuff out is the standard way. You get a copy of all the relevant standards as a foundation, ISO, POSIX, Window and stuff like CERT. Then you you get some of the system programming books (listed below). Then you find get some good reference code that show best practice. usually code from the operating system or utilities. Lastly read all the compiler docs and tool docs to set up the best code analysis framework you can.

These are a few system programming books that I use.

(best intro book) GNU/Linux Application Programming https://www.amazon.com/GNU-Linux-Application-Programming/dp/...

UNIX Systems Programming https://www.amazon.com/UNIX-Systems-Programming-Communicatio...

Advanced Programming in the UNIX Environment https://www.amazon.com/Advanced-Programming-UNIX-Environment...

Windows System Programming https://www.amazon.com/Programming-Paperback-Addison-Wesley-...

The Linux Programming Interface http://www.man7.org/tlpi/

edit: I'm not sure your skill level, you may have seen all of those but I posted them regardless. There is a lot of security and convention in those books.

Two alternative, and better, choices, if you're willing to spend a few dollars (and hopefully expense it to your manager):

The Linux Programming Interface: http://www.amazon.com/Linux-Programming-Interface-System-Han...

Advanced Programming in the UNIX Environment: http://www.amazon.com/Advanced-Programming-UNIX-Environment-...

A not-too-distant third choice, Linux System Programming: http://www.amazon.com/Linux-System-Programming-Talking-Direc...

As someone who is moving into more of a devops role from a pure development role. Here is my learning list so far.

1. The TCP/IP Guide: A Comprehensive, Illustrated Internet Protocols Reference. http://www.amazon.com/The-TCP-Guide-Comprehensive-Illustrate...

2. Advanced Programming in the UNIX Environment http://www.amazon.com/Programming-Environment-Addison-Wesley...

3. A systems programming language- I choose golang.

4. GDB/makefiles

5. SSH, The Secure Shell: The Definitive Guide: The Definitive Guide http://www.amazon.com/SSH-Secure-Shell-Definitive-Guide-eboo...

Here are few examples of great 1000+ pages books with lots of code. Though reading them is much more effort than reading a self-help book: http://www.amazon.com/Programming-Environment-Addison-Wesley... http://www.amazon.com/TCP-IP-Illustrated-Implementation-Vol/... http://www.amazon.com/Physically-Based-Rendering-Second-Edit...

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/Programming-Addison-Wesley-Professiona...

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.
