Best practices are for idiots. Learn pragmatism instead — Here on Medium, many articles are what I would call success porn. I made 10 million dollars last week and so can you with these 17 simple steps. Sure, bro. I don’t believe you but I’ll click your headline anyway because my monkey-brain is going haywire at the thought of…

Key points from a must-read book for programmers — I recently wrote about “5 Books That Changed the Way I Code.” In the comments, several readers recommended “Clean Code” by Robert C. Martin. As a result, I’ve now read the book and found it worthy of an in-depth review. About the Book “Clean Code” was published in 2008, and over recent years…

Taking a simple client-server interaction and exploring all the ways it could go wrong — In this article, I try to explain how one should reason about integrating software using synchronous remote calls (HTTP, RPC, etc.), …

An illustrated explanation of how idempotent systems allow for much simpler and less wasteful software integrations — Idempotence (or idempotency if you like), is a characteristic of an operation, such as an HTTP endpoint or an RPC call, allowing to execute it multiple times and observe the same result as if the operation was only applied once. In other words, when integrating with another system such as…

Make your web, desktop, CLI, and mobile apps technically good with these tips — Programmers work with various software projects: web apps, desktop software, mobile apps, and CLI tools. These software projects target either general computer users or developers. For example, a movie recommendation web app mainly targets general computer users who want to search for movies. …

We continue a journey through the SOLID principles by presenting the one which has the most significant impact on unit testing in Go — The Dependency InversionPrinciple. — Learning a new programming language is often a straightforward process. I often hear: “The first programming language you learn in a year. The second one in a month. Third one in a week, and then each next one in a day.”. Saying that is an exaggeration, but it is not…

Do you know how to avoid cache stampedes? — Leetcode has always been the holy grail to cracking the coding interview. Many engineers have said that the technical interview pipeline is broken. Three years ago, a technology company would not have told you to solve two Leetcode hard questions in a single setting. A lot of the technology companies…

A Garbage Idea For Brainless Programmers Incapable Of Independent Thought — Single responsibility principle. Single, responsibility, principle. Single. Responsibility. Principle. It should be obvious from that one line why I hate the single responsibility principle so much. But in case it isn’t here’s an entire article just elaborating. It’s The Slogan So recently we’ve seen some pretty questionable slogans. I mean there’s ‘defund the…

Uncle Bob’s SOLID principles are famous in the programming world. Almost every developer at least heard about them. They are considered common knowledge and you are told to follow them but I think these rules should not be followed blindly. I often find myself disagreeing with the “Do not repeat…

Basics of designing a software system with scalable example — So far we have discussed different software architecture topics in more low-level aspects, focusing on designing specific parts of software system separately such as backend, frontend, middleware etc. With this article we take the discussion to one step further and discuss designing a software system end-to-end. In designing whole system…

How to apply the Pareto principle! — It all started in Italy when Vilfredo Pareto observed that approximately 80% of the land in Italy was owned by 20% of the population. He came up with a principle popularly known as the 80–20 principle that states roughly 80% of consequences come from 20% of causes. The majority of…

Most programmers even don't know that they are writing bad code — If you are a programmer, I am sure you use something like Github to store your code. Just look at the old code you wrote a year ago or more. …

And it’s something that you probably do anyway — In my line of work, I read code all day, every day, be it code reviews of new features or making out head or tail of old ones. If you’re like me, you might even be going through code bases over decades old. That’s almost three centuries in the computer…

Unlocking everyone to make the impossible possible — Quotations are drops of thoughts that sometimes reach deep into our souls and give us insights that a hundred books cannot. I looked at various sources and found them, happy to share with everyone. Human “I’m not a great programmer; I’m just a good programmer with great habits.” by Kent Beck. …
