HTTP/3 is on the horizon, but many aren't even familiar with HTTP/2 yet. Find out what HTTP/3 means for web development, administration, and the internet.

Micro-frontend architectures decompose a front-end app into individual, semi-independent "microapps" working loosely together. This can help make large projects more manageable, e.g. when transitioning from legacy codebases.

Secure payment processing is a key prerequisite for any eCommerce operation. If it fails, the consequences can be catastrophic for any company, big or small. In this article, Toptal Ruby on Rails Developer Henrique Reinaldo Sarmento outlines how you can create a Ruby on Rails eCommerce app, leveraging PayPal and Stripe for reliable and secure payments.

Unwanted AI bias is already a widespread problem. Machine learning models can replicate or exacerbate existing biases, often in ways that are not detected until release. So what can be done about it?

Functional Programming is a paradigm of building computer programs using expressions and functions without mutating state and data. In this article, we will talk about doing functional programming using JavaScript. We will also explore various JavaScript methods and features that make it possible. In the end, we will explore different concepts associated with functional programming and see why they are so powerful.

The successor of the revolutionary ESP8266, the ESP32 is a next-generation microcontroller. Find out how to sample its analog-to-digital converter (ADC) from a timer interrupt using the Arduino IDE.

We reduce boilerplate with common OOP patterns, but often, the code overhead of using patterns is almost the same—if not bigger—than if we’d used boilerplate code in the first place. In aspect-oriented programming tutorial, we implement two functions (aspects) that allow for generic database connection management and caching. These allow us to mark methods that, when called, will automatically have the required functionally present in through IL weaving.

Pattern matching is a powerful tool commonly found in functional programming languages. The Ruby 2.7 release is going to include this feature. In this article, Toptal Ruby Developer Noppakun Wongsrinoppakun provides a breakdown of what this addition will include and why it matters.
