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.

In an age of continuous delivery, Java developers have to be confident that their changes don't break existing code, hence automated testing. There's more than one valid approach to it, but how can you keep them straight?

Nearly every app requires an authorization system on top of an authentication system. We often need a fine-grained permissions model to allow only specific users to access certain resources while simultaneously restricting access for everyone else. In this tutorial, Toptal Freelance Firebase Developer Joaquin Cid teaches how to build just such a system. Called a role-based authentication, we’ll learn how to implement this system in an API using Node.js and Firebase.

Subscription-based apps need a special approach when it comes to analytics. Learn how a variation on the traditional sales funnel helps you work with LTV, subscriber retention, and churn rates to make your app better—and more profitable.

In an era of cross-platform mobile development, it is crucial to understand the specifics of different operating systems and hardware. In this article, Mobile Developer Martin Doychev lists a number of bad practices employed while creating apps for iOS and Android and explains what you should and shouldn’t do.

Apple’s iOS SDK features a bevy of built-in UI components, but what happens when you decide you need a bit more? What if you need to create a swipeable UITabBar? In this post, Toptal iOS Developer George Vashakidze explains how he tried using a third-party library, and why he chose to create his own solution instead.

Building a mobile app isn't cheap—and the harsh reality is that most apps fail. Find out how to leverage fundamental analytics metrics to make sure your app actually turns a profit.

You can just write sequentially executed code in JavaScript, but should you? In this article, Toptal Freelance JavaScript Developer Omar Waleed tests the widespread Node.js belief that synchronous code degrades performance and is, in a sense, just plain evil. Is this really true?
