Protocol Buffers (protobuf) is a language-neutral mechanism for serializing structured data. Used in distributed systems, APIs, and microservice architectures where efficient communication between services is important. Protobuf serializes data into a compact **binary representation**. This makes messages smaller and generally faster to serialize, transmit, and deserialize.

The Power of Ten. Rules for Developing Safety-Critical Code in JavaScript

Posted on: April 26, 2025

To make this clear from the start, this article has my opinion on how to translate to JavaScript The Power of 10: Rules for Developing Safety-Critical Code, which was written with 'C' in mind. In safety-critical software systems, such as medical devices, aviation industry etc, reliability has primacy. Here’s how Gerard J. Holzmann's Power of Ten can be applied to JavaScript.

The Half-Distance Paradox. Simulation in Go

Posted on: March 23, 2025

In this article, we'll explore a fascinating concept often referred to as the "half-distance paradox," using Go. This paradox comes from an idea in mathematics and philosophy, where a person or object is thought to always halve the distance between themselves and their goal, making it appear that they can never actually reach their destination. This program will simulate the concept and give us some insight into the way it behaves in computing.

The minimum subarray problem with JavaScript

Posted on: October 3, 2024

The Minimum Subarray Problem can be compared to real-world scenarios where you want to minimize some negative outcome over a period of time or across sequential steps. Here's how it could relate to several real-life situations...

August 24, 2024 - Cutting corners will bite you back. Or maybe not, but someone will feel the pain

As a programmer, it is very easy to fall into the trap of cutting corners, neglecting the way you are writing code. I've worked in quite a few companies in the last few years and these are the most common corner cuts that I`ve noticed among my colleagues.

April 19, 2024 - What are React Server Components? How it works?

This time around we are not dealing with a new fancy API but rather a new application architecture whict lets you fetch data in asynchronous components that run on the server or even during the build time. Let's have a look at what React team has in the store for the future.

March 19, 2024 - This is how a Javascript engine works

A JavaScript engine is a program that converts code into machine-readable instructions which can be executed by the computer's hardware. Modern JavaScript engines no longer just interpret code, they compile it. V8 is a JavaScript engine developed by Google for Chrome and Chromium web browsers. V8 is written in C++, it is portable and runs on Mac, Windows, Linux and other systems. Because of it's popularity, V8 will be the subject to disect in this article.

December 22, 2023 - Destroy event listeners with AbortController

The other day, I came across an unconventional usage for AbortController API. I was aware that AbortController can be used for better control over web requests, but I never thought to leverage it with event listeners. I assume you know how to use the traditional EventTarget: removeEventListener() method so I will not talk about that, today we are talking about an alternative.

July 27, 2023 - Using asyncio for concurrent http requests with Python (asyncio.ensure_future and asyncio.gather)

Python has a few ways for implementing fetching data using http with various packages. "requests", "asyncio", etc. In this article will make a practical example that demonstrates how to run 100 requests concurrently as asyncio tasks and then how to save the results to a file as json, using asyncio.ensure_future and asyncio.gather. Why would I want to use asyncio.ensure_future and asyncio.gather? Click the article to read more ...

May 7, 2023 - Python vs JavaScript snippets

I've started recently to use Python with Scrapy. Naturally, when I need to do certain things like spreading a list of values or using a try/catch block, my brain attempts initially to write code the way we do it in JavaScript. (I've done mainly JavaScript for the last 7 years or so) Assuming you are new to Python too, these snippets are meant to stimulate our brain's neuroplasticity. Enjoy.

January 22, 2023 - What is a packet?

Any data sent over the Internet is divided into smaller segments called packets. In networking, a packet is a small segment of a larger payload. Data sent over computer networks is divided into packets. These packets are then recombined by the computer or device that receives them.

October 15, 2022 - Functions As Values, JS functions tutorial

Function definition and invocation are syntactic features of JavaScript and of most other programming languages. In JavaScript, however, functions are not only syntax but also values, which means they can be assigned to variables, stored in the properties of objects or the elements of arrays, passed as arguments to functions, and so on.

October 9, 2022 - Another SOLID article, the SOD.

These principles should be taken as a guide, should have a place in your thinking as a suggestion and not as a religious dogma. In this article I am going to discus 3 of the 5 principles, hence the SOD. Why the SOD? Because these are the principles I find most applicable in my day to day tasks.

September 15, 2022 - Implicit and explicit coercion in JavaScript

JavaScript is a weakly-typed language, values can also be converted between different types automatically. This is what we call implicit type coercion. We also have the ability to convert values in a more implicit way using various techniques. This is an article about the implicit and explicit (type casting) type coercion in JavaScript.
