Before you use Unity’s straightforward and intuitive tool for multi-platform development, become familiar with and avoid these common Unity mistakes.

Clustering algorithms are very important to unsupervised learning and are key elements of machine learning in general. These algorithms give meaning to data that are not labelled and help find structure in chaos. But not all clustering algorithms are created equal; each has its own pros and cons.

In this article, Toptal Freelance Software Engineer Lovro Iliassich explores a heap of clustering algorithms, from the well known K-Means algorithm to the elegant, state-of-the-art Affinity Propagation technique.

Software engineers are always searching for the best tools and guides to help them be more productive and allow them to spend less time reading long technical specifications.

Today, Toptal is pleased to present a new resource to the community: the JavaScript Cheat Sheet - ES6 and Beyond. Toptal’s JavaScript Cheat Sheet is a quick, easily understandable reference guide. It is free to download and includes all the new and exciting features introduced with ES6 as well as the future experimental features from ES7.

It’s tragically common for developers to come into a project where proper automated testing has been and will continue to be overlooked. It’s a situation Freelance Developer Bhushan Lodha has found himself in all too often; fortunately, he’s found a solution. In this article, he briefly covers the reasons why testing is overlooked and ultimately explains his “coding life hack” to ensure quality control even when he can’t introduce a testing framework.

Some platforms have an overwhelming number of options for web frameworks. Node.js, the event-driven server-side JavaScript environment, is one such platform. Whether it’s the minimalist Express or the full-blown MVC web framework Sails.js, Node.js seems to have it all.

In this article, Toptal Freelance Software Engineer Chuoxian Yang explores four of the most popular Node.js web frameworks and discusses how each framework stands out from the rest of the crowd in Node.js.

In a nutshell, declarative programming consists of instructing a program on what needs to be done, instead of telling it how to do it. This approach involves providing a domain-specific language (DSL) for expressing what the user wants. This DSL shields users from messy low-level constructs while still achieving the desired end-state.

While declarative programming offers advantages over the imperative approach it replaces, it’s not as straightforward as it may seem. In this comprehensive article, Toptal Freelance Software Engineer Federico Pereiro outlines his experience with declarative tools and explains how you can make declarative programming work for you.

Today, writing applications in languages that compile to JavaScript is a very common practice. Scala developers, for example, can use Scala.js and have the same language for both the server and the client. That said, Scala’s compiler and standard dependency management tools are too limiting in the modern JavaScript world.

In this article, Toptal Freelance Software Engineer Michele Sciabarra shows us how to integrate Scala.js with the plethora of JavaScript modules available on NPM, using tools like Browserify, and explains how to do this without even having to install Node.js.
