Rule of Composition: Design programs to be connected to other programs. Another good lesson that the author provides is – reuse code. Their “Don't Repeat Yourself” rule is: every piece of knowledge must have a single, unambiguous, authoritative representation within a system.In this book we prefer, following a suggestion by Brian Kernighan, to call this the Single Point Of Truth or SPOT rule. Rule of Simplicity Developers should design for simplicity by looking for ways to break up program systems into small, straightforward cooperating pieces. This rule aims to discourage developers’ affection for writing “intricate and beautiful complexities” that are in reality bug prone programs. Do not reinvent code that has been developed a long time ago. 0-1. You may ask yourself: “How can I write complex and simple programs?” It all depends on the situation and Raymond provides you with some intuitive guidelines. Transparency is important.

Part six, the “code-saving rule” I continue the series of articles devoted to some simple rules for developing under Unix “according to Eric Raymond ”, which, in my deepest conviction, can be extended to any other operating system. Communication between modules, well known words like IPC, pipes, redirections, sockets, shared memory, streams, RPC and threads are the basic idea behind the chapter entitled “Multiprogramming” which can also be called multiprocessing, just don’t confuse this term with the term used for the hardware implementation of two or more CPUs. As we move on you learn about protocols, text formats and other formats found in operating systems. Rule of Robustness Developers should design robust programs by designing for transparency and discoverability, because code that is easy to understand is easier to stress test for unexpected conditions that may not be foreseeable in complex programs.

The Art of UNIX Programming poses the belief that understanding the unwritten UNIX engineering tradition and mastering its design patterns will help programmers of all stripes to become better programmers. Simply because programming is complex enough and if your code is dirty, in a few weeks time you may not know what you were thinking when writing the code. Score: 5. Rule of Least Surprise Developers should design programs that build on top of the potential users’ expected knowledge; for example, ‘+’ should always mean addition in a calculator program. I’m sure this chapter will help you decide on what language to use for a specific job. Art of UNIX Programming, The - Kindle edition by Raymond, Eric S..

Raymond discusses the philosophy of Unix, what it got right, and what it got wrong. Rule of Parsimony Developers should avoid writing big programs. This rule aims to prevent overinvestment of development time in failed or suboptimal approaches caused by the owners of the program’s reluctance to throw away visibly large pieces of work. 2. Here you find descriptions on traditional utilities and formats, as well as recommendations for writing good documentation. The book begins with some basic facts about UNIX. It’s a valuable asset if you are knowledgeable about hardware implementations and knowing the operational cost of the code you write. Raymond illustrates some common but important things about these operating systems and then he examines them. Full Abbreviated Hidden /Sea.
