The Self-Taught Computer Scientist. Cory AlthoffЧитать онлайн книгу.

Introduction

      My journey learning to code started when I graduated from college with a political science degree. After I left school, I struggled to get a job. I didn't have the skills employers were looking for, and I watched as my friends who studied more practical subjects went on to get high-paying jobs. Meanwhile, I was stuck applying for jobs and not getting them, making no money, and feeling like a failure. So, living in Silicon Valley and being surrounded by coders, I decided to try to learn to program. Little did I know that I was about to start the craziest and most fulfilling journey of my life.

      This attempt wasn't my first shot at learning to code: I had tried to learn to program in the past without success. During my freshman year of college, I took a programming class, found it impossible to understand, and quickly dropped it. Unfortunately, most schools teach Java as a first programming language, which is challenging for beginners to understand. Instead of Java, I decided to teach myself Python, one of the easiest languages for beginners to learn. Despite learning an easy-to-understand language, I still almost gave up. I had to piece together information from many different sources, which was frustrating. It also didn't help that I felt like I was on my journey alone. I didn't have a class full of students I could study with and lean on for support.

      I was close to giving up when I started spending more time in online programming communities like Stack Overflow. Joining a community kept me motivated, and I began to gain momentum again. There were many ups and downs, and at times I felt like quitting, but less than a year after I made my fateful decision to learn to program, I was working as a software engineer at eBay. A year earlier, I would have been lucky to get a customer support job. Now, I was getting paid $50 an hour to program for a well-known tech company. I couldn't believe it! The best part wasn't the money, though. Once I became a software engineer, my confidence increased tenfold. After learning to code, I felt like I could accomplish anything.

      After eBay, I started working at a startup in Palo Alto. Eventually, I decided to take some time off work and go on a backpacking trip to Southeast Asia. I was in the backseat of a taxi driving through the narrow streets of Seminyak, Bali, in the rain when I had an idea. Back home, people were always asking me about my experience as a software engineer. Working as a software engineer in Silicon Valley is not unusual, but I was different from many of my peers because I do not have a computer science degree.

      My idea was to write a book called The Self-Taught Programmer: not only about programming but about everything I learned to get hired as a software engineer. In other words, I wanted to help people take the same journey I did. So I set out to create a roadmap for aspiring self-taught programmers. I spent a year writing The Self-Taught Programmer and self-published it. I wasn't sure if anyone would read it, and I thought most likely no one would, but I wanted to share my experience anyway. To my surprise, it sold thousands of copies in the first few months. With those sales came messages from people from around the world who were either self-taught programmers or wanted to become one.

These messages inspired me, so I decided to help solve another problem I faced learning to program: feeling alone on the journey. My solution was to create a Facebook group called Self-Taught Programmers, a place for programmers to support one another. It now has more than 60,000 members and has evolved into a supportive community filled with self-taught programmers helping each other by answering questions, trading knowledge, and sharing success stories. If you want to become part of our community, you can join at https://facebook.com/groups/selftaughtprogrammers. You can also subscribe to my newsletter at theselftaughtprogrammer.io.

      When I used to post things online about working as a software engineer without a computer science degree, I would always get at least a few negative comments that it is impossible to work as a programmer without a degree. Some people would cry, “What do you self-taught programmers think you are doing? You need a degree! No company is going to take you seriously!” These days, the comments are few and far between. When they do come, I point the commenter to the Self-Taught Programmers group. We have self-taught programmers working at companies worldwide in every position, from junior software engineers to principal software engineers.

      Meanwhile, my book continued to sell better than I ever thought possible and is even a popular Udemy course as well. Interacting with so many wonderful people learning to program has been an amazing and humbling experience, and I am excited to continue my journey with this book. This book is my follow-up to my first book, The Self-Taught Programmer, so if you haven't already read it, you should go back and read that first, unless you already understand programming basics. This book assumes you can program in Python, so if you can't, you can either go back and read my first book, take my Udemy course, or learn Python using whatever resource works best for you.

What You Will Learn

      While my first book, The Self-Taught Programmer, introduces programming and the skills you need to learn to program professionally, this book is an introduction
