Leveling Up With Gary Bernhardt's Destroyallsoftware Series

July 31, 2023


I believe that continuous learning and practice are key to staying ahead in the ever-evolving world of software development. Recently, I stumbled upon an exceptional resource that has been highly recommended by many experienced programmers – Gary Bernhardt’s “destroyallsoftware” series. In this blog, I will share my experience diving into this series and how it has helped me strengthen my coding fundamentals. To illustrate my journey, I will focus on a specific project I worked on from the “from-scratch” repository and discuss the valuable insights gained from this process.

Gary Bernhardt and His destroyallsoftware Series:

Gary Bernhardt is a renowned programmer and educator who has gained a strong following for his in-depth and well-crafted educational content. The “destroyallsoftware” series is one of his most notable contributions to the programming community. The series covers a wide range of topics, including software design, testing, debugging, and performance optimization. Gary’s teaching style is engaging and enlightening, making complex concepts accessible to learners at various skill levels.

Investing in My Learning Journey:

Recognizing the significance of strengthening my coding basics, I decided to dedicate some focused time to learning from the “destroyallsoftware” series. My plan was simple: pick one of Gary’s videos and follow along, actively coding alongside him. To track my progress and share my work with others, I created a repository on GitHub: https://github.com/vinitkumar/from-scratch.

The “from-scratch” repository houses various projects, each designed to teach the fundamentals of a specific programming concept. For this blog, I chose the “malloc-from-scratch” project (https://github.com/vinitkumar/from-scratch/tree/main/malloc-from-scratch). This project aims to implement a basic memory allocation mechanism from scratch, an essential skill for any programmer.

My Weekly Learning Routine:

I decided to challenge myself and set a goal of completing one project from the “from-scratch” repository every week. This schedule allowed me to delve deeply into each topic while maintaining a sustainable learning pace. I believed that the combination of guided learning from Gary’s videos and hands-on coding practice would be the most effective way to solidify my understanding of core concepts.

The malloc-from-scratch Project:

With excitement and determination, I began working on the “malloc-from-scratch” project. The task involved implementing a simplified version of the malloc function, which dynamically allocates memory during program execution. Though it seemed daunting at first, Gary’s video provided a clear and concise breakdown of the process, making it less intimidating.

I followed along with Gary, typing out the code as he explained each step. While coding, I encountered some challenges, but I found that these obstacles were valuable learning opportunities. They forced me to think critically, debug, and understand the underlying mechanisms better. Additionally, the satisfaction of seeing my code work correctly was immensely rewarding.

Key Insights and Takeaways:

As I progressed through the project, I gained several essential insights and takeaways:

  1. Understanding Memory Allocation: Implementing malloc from scratch deepened my understanding of memory allocation and management. I learned about the heap, memory fragmentation, and the importance of pointer arithmetic.

  2. Debugging Skills: During the coding process, I faced bugs and logical errors. Debugging these issues sharpened my troubleshooting abilities and taught me to use tools like GDB effectively.

  3. Software Design Principles: Gary’s approach to software design emphasized simplicity, readability, and modularity. These principles have influenced the way I approach coding, leading to more maintainable and scalable code.

  4. Appreciation for Standard Libraries: Creating a memory allocator from scratch made me appreciate the robustness and complexity of standard libraries. It also helped me comprehend the necessity of these foundational components in any programming language.

  5. Confidence in Coding: Tackling challenging projects alongside an experienced instructor gave me confidence in my coding skills. I realized that with determination and the right resources, I could tackle complex problems.

Keeping the Momentum Going:

Having completed the “malloc-from-scratch” project, I am motivated to continue my weekly learning routine. The experience of learning from Gary Bernhardt’s “destroyallsoftware” series has been transformative for my programming journey. Each week, I look forward to selecting a new project and delving into exciting and diverse programming concepts.


Gary Bernhardt’s “destroyallsoftware” series has proven to be an invaluable resource for my coding education. The combination of guided learning through videos and hands-on coding practice has helped me strengthen my foundational knowledge and hone my programming skills.

I would highly recommend Gary’s series to anyone looking to level up their coding skills, whether you are a beginner seeking a solid foundation or an experienced developer striving for continuous improvement. Investing time in learning from Gary Bernhardt is a worthwhile endeavor that will undoubtedly pay dividends in your programming journey. I am excited to continue my weekly learning routine and explore more of the “destroyallsoftware” series, as I strive to become a better programmer each day.
