• Principle of Least Astonishment

  Systems should behave in a way that is least surprising to the user. This idea is the overarching theme of many of my thoughts on product development. It shows up again and again in different places.

• Hotspot performance engineering fails

  Developers often believe that software performance follows a Pareto distribution: 80% of the running time is spent in 20% of the code. Using this model, you can write most of your code without any care for performance and focus on the narrow pieces of code that are performance sensitive. Engineers like Casey Muratori have rightly criticized this model. You can read Muratori excellent piece on his blog.

• Five Common Mistakes To Avoid When Learning Golang

  Golang (or Go) is an open-source programming language that was developed by Google engineers. It was designed to build efficient, reliable, and robust applications, and it is a statically compiled language used for building modern and scalable applications. Go is known for it’s concurrency support, which makes it easy to write programs that can perform multiple tasks simultaneously. It has a garbage-collected runtime and a rich standard library, making it easy to develop applications without relying on external dependencies.

  It has gained popularity among developers over the years for a variety of reasons. One of the main reasons is its simplicity. Go has a clean, easy-to-learn syntax, which makes it easy for new developers to pick up and start using. Additionally, it places a strong emphasis on readability, which makes it easier for teams to collaborate and maintain code. Go is also known for its performance. It is a compiled language, which means that it is compiled into machine code that can be directly executed by the computer’s processor. This makes Go programs fast and efficient, especially when compared to interpreted languages like Python or Ruby. However, when learning Golang, there are common mistakes made by beginners or experienced developers in understanding basic concepts.

  In this article, we will go over these five common mistakes and how to ensure we avoid them.
