The author aims to leverage Go's concurrency and parallelism for projects requiring significant number crunching but seeks even greater performance through SIMD (Single Instruction Multiple Data) capabilities at the hardware level. While many programming languages support SIMD through compiler optimizations or libraries, the author notes that Go's compiler does not utilize SIMD and could not find a suitable general-purpose SIMD package. Thus, they decided to create their own package that provides a thin abstraction layer for arithmetic and bitwise SIMD operations. During their research, they

The article discusses the Rack protocol, which defines how Rack servers, applications, and middleware interact. It clarifies that while the rack gem provides helpful development tools, using it is not mandatory for creating Rack components; as long as they comply with the Rack protocol, they are considered Rack servers, applications, or middleware. The article focuses on understanding these components through practical examples, including building a dummy Rack server. A Rack server's main role is to act as an HTTP server, handling requests and responses,

Ruby is recognized for its flexibility and metaprogramming features, particularly the `instance_exec` method. This method allows developers to execute a block of code in the context of an object's instance, which is especially useful in Ruby on Rails applications. By utilizing `instance_exec`, developers can access instance variables and methods that would normally be inaccessible outside the class. The method belongs to the Object class, so it is available to all Ruby objects. It accepts a block and optional arguments, enabling dynamic code execution
