Go has a built-in testing framework provided by the testing package, that makes writing tests easier, but how do we write a more complicated test that requires mocking? In this post, we will learn how to take advantage of structs and interfaces in Go to mock any service or library…

With examples in Go (Golang). — Whether you’re just getting started with programming, or you have years of experience, you’ve likely at some point of the time will do or have done some performance test of your application to measure the Latency (Latency is defined as the time it took one operation to happen). When it…

A simple and brief introduction to CSP, it’s terminology, and it’s similarities to Go. — Communicating Sequential Processes (CSP) for short, is what we hear whenever a Go concurrency is discussed and how it’s an elixir for concurrent programming. When I heard this term for the first time, I started to think that, Is CSP some sort of new technique or an algorithm that makes…

When I first started trying to understand the memory allocator of Go, it was maddening. Everything seemed like a mystical black box. As almost every technical wizardry is hidden beneath abstractions, you need to peel off those layers one by one to understand it. In this blog post, we will…

A detailed look of the Go type system, with examples — Let’s begin by asking a fundamental question. Why we need a type? Before answering that, we need to look at some of the primitive abstracted layers of programming languages that we don’t usually deal with. How close can we get to a machine representation of data?

An “ins and out” of the internal implementation of the Golang channels and its related operations. Concurrency in Golang is much more than just syntax. It a design pattern. A pattern that is a repeatable solution to a commonly occurring problem while working with concurrency, because even Concurrency Needs to…

The title may lead you to think that this post is another ranting post about the downside of a “Single Page Application”. It is more about shedding some light on the performance perspective to keep in mind while designing the SPA. …

The web application uses the browser/server architecture, HTTP as the communication protocol. HTTP is a stateless protocol. Each time the browser requests, the server processes it independently and does not associate with the previous or subsequent request. But it also means that any user can access the server resources through…

I completely agree with the fact that “premature optimization is the root of all evil (or at least most of it) in programming”. …
