Pearson Clean Code: A Handbook of Agile Software Craftsmanship

Excelente libro

Every so often, a book comes along that codifies best practice in a way that manages to illuminate the path from where things are right now, to a better place that we'd rather be -- things like Fowler et al. Refactoring: Improving the Design of Existing Code (Object Technology Series) or the Gang of Four Design patterns : elements of reusable object-oriented software . This is one of those books. And if much of the material is the sort that seems obvious in hindsight -- well, that is the mark of a well written book, to make the concepts that clear. Taking a series of real world examples -- open source projects with significant user bases, including FitNesse and JUnit -- a series of worked examples take us from good, or at least adequate, code, to a form which is better factored, and easier to read, with the steps along the way clearly marked. Yes, even some of Kent Beck's code is put under the microscope, and carefully polished that extra stage or two more. The reader is cautioned that, without working long hours to follow these examples, this will be just another of those feel-good books. I don't quite agree -- spending just a little time to follow the transformations, and then reflecting on one's own outpourings should be enough to make this a feel-bad book. All the sins from obscurely named variables to sprawling functions that gaily mix abstraction levels, we've all done them (especially programming in FORTRAN on minicomputers with slow stacks and a rule of thumb that 1 call ~ 40 loc in terms of performance). The maxim to take from the book is based on Baden-Powell's "Try and leave this world a little better than you found it", and owes to the same school of thought as "whenever you are in the garden, pull at least one weed". The meat of the book is in distinguishing what are the weeds from the intended crop. So read it, understand the examples, and then refer to it often -- like the other titles mentioned, it is a reference work, and should join them as among the most thumbed on your bookshelf.

Está centrado en el lenguaje Java, pero puede ser útil con otros lenguajes de programación porque se explica bastante bien. El libro pasa por casi todos los aspectos que se puede encontrar durante la codificación de un programa. Indica las situaciones en las que nos encontramos a menudo, y cómo resolverlas teniendo en mente que lo que quedará de nuestro trabajo es el código. Y siempre se vuelve al código, ya sea un mismo u otra persona. La idea principal es que éste debe ser claro, limpio y lo más descriptivo posible, lo que pasa por evitar vicios y soluciones sofisticadas. Vale la pena sin duda, y sirve para darse cuenta que todo lo que nos pasa por la cabeza cuando se codifica, nos pasa a todos, darnos cuenta de ello y decidir lo qué queremos hacer. Si ya tienes unas pautas de estilo bien marcadas, quizás no sea tan provechoso como para un principiante.

This is a great book. I have found the concepts informative and helpful. I'm glad I decided to get it. As an aid, I listened to the audio book version while I followed along reading it. This made taking notes a dream. I am now on my way to leveling up my programming skills.
