Back-end

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.

Single sign-on is great for users, sparing them from memorizing yet another password; for businesses, removing frictio; and for developers, since less code means less things that can go wrong. In this Flask login tutorial, we’ll write a step-by-step guide to add a SSO login button into a Flask application with SimpleLogin and Facebook as an identity provider.

For a successful natural language processing project, collecting and preparing data, building resilient pipelines, and getting "model ready" can easily take months of effort even with the most talented engineers. But what if we could reduce the data required to a fraction? In this article, we’ll cover how transfer learning is making world-class models open source and introduce BERT (bidirectional encoder representations from transformers). BERT is the most powerful NLP “tool” to date. We’ll explore how it works and why it will change the way companies execute NLP projects.
