Updating live applications used to be a tedious and somewhat risky affair, but with the emergence of modern development frameworks and tools, updates and deployment are becoming straightforward.

In this article, Toptal Java Developer Elene Latsoshvili explains how you can update a Laravel app with zero downtime, and how this can be done for most PHP applications.

The Ethereum Name Service is a blockchain-backed alternative to the internet’s traditional Domain Name System. If you own a .eth domain, you can deploy smart contracts that let users set up their own subdomains—but then, of course, you’ll want a corresponding ĐApp to make it user-friendly. In this tutorial, Toptal Freelance Ethereum Developer Radek Ostrowski provides complete coverage of this scenario, this time with a focus on ĐApp development.

JavaScript’s default synchronous methods can freeze an application, scaring off end users. Here’s how you can leverage asynchronous JavaScript techniques to increase control over front-end responsiveness.

In an era of subdued prices and with usage expected to plateau within the next 30 years, the focus for oil and gas companies must turn to cost control. Applying technological innovations such as blockchains, wearables, and advanced analytics to the supply chain can keep costs in check and maintain profitability.

Generative AI is taking the world by storm, with potentially profound impacts on the content we create. Learn the basics of AI image generation and produce sophisticated artistic renderings with this tutorial.

Nowadays, front-end development workflows involve many modern tools and preprocessors that not only streamline the whole process, but also allow you to spend less time on common web tasks, giving you more time to focus on other aspects of the project that require more careful and skilled insight. Sass, the scripting language for syntactically awesome stylesheets, comes with robust and built-in support for mixins - an essential feature for keeping your stylesheets DRY.

In this article, Toptal Freelance Software Engineer Justin Brazeau shows us 10 useful Sass mixins that help keep your stylesheets manageable by breaking them into smaller reusable bits, each with its own focus.

In Part I of this three-part series, we saw how the free motion of rigid bodies can be simulated. In Part II, we saw how to make bodies aware of each other through collision and proximity tests. Up to this point, however, we still have not seen how to make objects truly interact with each other. The final step to simulating realistic, solid objects, is to apply constraints, defining restrictions on the motion of rigid bodies.

In this article, we’ll discuss equality constraints and inequality constraints. We’ll describe them first in terms of a force-based approach, where corrective forces are computed, and then in terms of an impulse-based approach, where corrective velocities are computed instead. Finally, we’ll go over some clever tricks to eliminate unnecessary work and speed up computation.

By adopting a global talent acquisition strategy, venture capital not only extends the opportunities of entrepreneurship across the world, it helps startups reduce churn and break even faster.

While Redux is a great state management solution, it doesn’t support asynchronous behavior by default. A way around this is to use redux-observable, based on RxJS - a powerful library for reactive programming in JavaScript.

Requirements gathering is a crucial but often overlooked part of the development process. Steer clear of these five ineffective approaches and identify meaningful ways to improve your requirements gathering process.

WebVR is bringing virtual reality to our browsers, but how do we make sure we have enough computing power to deliver a good experience? How do we make the most of multi-core, hyperthreaded processors?

In part two of our series, Toptal Full-stack Developer Michael Cole explains the basics of browser edge computing and the role of web workers.
