Supervised learning is the key to computer vision and deep learning. However, what happens when you don’t have access to large, human-labeled datasets? In this article, Toptal Computer Vision Developer Urwa Muaz demonstrates the potential of semi-supervised image classification using unlabeled datasets.

Inspired by stale-while-revalidate cache control logic, modern sites implement stale-while-refresh logic on the UI side. Thankfully, React Hooks make this logic painlessly reusable across components.

Writing multiple native applications for different mobile platforms can be a daunting task, but taking a non-native approach comes with pitfalls of its own. In this article, Toptal Mobile Developer Joel Frank outlines the concept of Write Once, Deploy Everywhere (WODE) and explains how to choose the right development path for your project.

The main artifact of all your work is most likely plain text files. So why don't you use Notepad to create them? Find out how the Language Server Protocol can transform text editors into code editors, without coupling.

Shopping online is more convenient than ever, so how do you create an online marketplace tailored to cater to your specific needs? In this article, Toptal JavaScript Developer Konrad Gadzinowski explores marketplace business models and payment methods for both regional and global services.

Internet privacy's cutting-edge technology includes encrypted server name indication (ESNI) and encrypted DNS in the form of DNS over HTTPS (DoH). Find out what they are, why they exist, and how they work.

Markov Chain Monte Carlo (MCMC) methods let us compute samples from a distribution even though we can’t do this relying on traditional methods. In this article, Toptal Data Scientist Divyanshu Kalra will introduce you to Bayesian methods and Metropolis-Hastings, demonstrating their potential in the field of probabilistic programming.

With all building blocks in place, it is time to wrap up our WebVR journey and demonstrate how everything is implemented. In the last part of our WebVR series, Toptal Full-stack Developer Michael Cole goes over design and implementation in detail, explaining how the experience comes together.
