510 pages, published in 2004. The book is quite old for a tech-book but it has aged exceptionally well. It only shows age in a few unimportant areas in my opinion.
The concepts presented in the book have revolutionized me as a developer! Read it multiple times and with great attention to internalize all the knowledge it contains, it will be worth it. To really understand the concepts and integrate them you should also build a project as you read the book where you implement the examples.
I cannot recommend this book enough! Below is my notes from reading the book, it is partly a summary of each chapter and partly my own thoughts about the content.

This book is a must read for any serious software developer. It gives a high-level overview of software development that is missing from other more code-oriented books. The primary focus is on Object-Oriented Programming and how we build systems that are maintainable, flexible, extendable and correct. But the approach is high-level so not many code examples.
At 321 pages and 34 chapters, it is not the most extensive book, and it is an easy read because so much of the advice makes perfect sense. But it still has so much depth that I think it can be read multiple times to get all the nuggets of wisdom.
A different view on the book is from Blaine Osepchuk. The only criticism I have of the book is that some of the chapters feel more like intros and does not cover the theme adequately.
I have collected my notes from the book here for all to benefit. But the notes do not give the book the needed credit so please take the time to read it.

Your deployment environment is a tool that should be sharpened to allow maximum productivity. I have seen many developers where their deployment environment is less than optimal, hurting their productivity.
Ranging from, developing directly on production sites. To develop on a shared server. And finally using a local development environment, which I think is the most optimal way to do it.
Developing directly on production is “fast”, but remember the quote
Slow and steady wins the race
If you develop directly in production, the business will be all over you when you break things, and you will break things! So take the time to get a setup that allows you to go fast in the future.
A local development environment has many advantages and with Docker, it is easy to set up. I will show how I handle the setup for my development. Including tip for how you can take advantage of a local development environment.

When you have worked in a specific area for a long time, many of the tasks begin to be repetitive. One way to keep sharp is to engage the brain with programming puzzles. A site that contains many puzzles is hackerrank.com. The name is a bit over the top for my taste, but they keep an extensive list of many different programming challenges.
Each challenge is solved in the programming language you choose. It makes a great way to both keep the skills up to date and practice using programming languages that you do not use that often. Especially the challenges that are rated medium and up are good for keeping your skills sharp.
I have tried to tackle one of the most difficult challenges; spy game revisited if you keep on reading there will be spoilers so if you want to solve the problem your self, please stop reading. I will implement the solution using C# .NET. You can find the code here.
