What’s the biggest problem with crowdfunding today? Everyone wants a sweet slice of the crowdfunded pie, but nobody wants a single crumb of responsibility. As a result, crowdfunding platforms, the tech press, and the geek public have picked up a track record filled with spectacular crowdfunding failures.

In this article, Toptal Technical Editor Nermin Hajdarbegovic takes a look at the state of crowdfunding today and explains why the industry needs to do more to clean up its act and get rid of bad apples in crowdfunding.

Java may have stood the test of time, but it can still be a source of great frustration among many web developers. Dealing with its verbosity and infrastructure overhead, for example, can take hours, even for the most basic needs.

In this article, Toptal Freelance Software Engineer Gregor Ambrozic shows us how Grails and its many appealing features can be a viable alternative to traditional Java web applications frameworks.

Elixir, with its simple and clean syntax, makes building scalable and maintainable concurrent applications a breeze. Ecto is a database wrapper that lives up to the high expectations set by Elixir’s reputation. Its domain-specific language provides a pleasant way to interact with databases and build fault-tolerant, concurrent applications in Elixir with ease.

In this article, Toptal Freelance Software Engineer Boris Barroso walks us through Ecto and its four main components: Repo, Schema, Changeset, and Query.

Many social networks provide APIs that enable the development of apps that expand their functionalities and grant access to user data and insights. This article compares popular social media APIs and gives examples of how to use them.

In today’s world, code is expected to change as quickly as requirements do, and tests play an important role in making that possible. Many modern projects boast great test coverage, making them more resilient to regression issues. However, that is not true for all projects - especially some legacy projects which have little in the way of testing.

In this article, Toptal Freelance Software Engineer Andrey Shalitkin discusses two metrics, coupling and cyclomatic complexity, that are important in identifying which portions of code to include in test coverage.

In the realm of enterprise software, especially for software provided as a service, multitenancy ensures that data is truly isolated for each client within a shared instance of software. Among its numerous benefits, multitenancy can greatly simplify release management and cut down costs.

In this article, Toptal Freelance Software Engineer André William Prade Hildinger shows us how Hibernate, a persistence framework for Java, makes implementing a multitenant Java EE application easier than it sounds.

Of all the modern ways people talk to each other, email seems to have stood the test of time and is arguably still one of the most effective and widely used means of communication. Thus, being able to programmatically send and receive emails can open new dimensions to a user’s experience of software that powers human communication.

In this article, Toptal Freelance Software Engineer Francis Altomare shows us how he leveraged various Amazon Web Services technologies to build a simple communication application in which email itself is an important interface.

Memory issues in programs can be quite frustrating whether you’re the user or the developer attempting to solve the problem. In Ruby, the garbage collector plays a vital role in managing your program’s memory so that you can focus on other important things. However, it is often possible to overwhelm the garbage collector or end up with sneaky resources that cannot be freed, which can lead to all sorts of memory issues.

In this article, Toptal Freelance Software Engineer Bruz Marzolf explains why certain memory issues arise in Ruby applications and how to tackle them easily.

Java has been a dominant programming language for ages, but modern times call for modern languages. Meet Kotlin, a modern, clear, and expressive programming language powered by the same virtual machine technology that powers Java.

In this article, Toptal Freelance Software Engineer Tomasz Czura takes us for a spin through the world of Kotlin and shows us how it can be used to make an Android application with an elegant architecture without compromising the very qualities of the code that Kotlin aims to provide.

The plethora of tutorials on building Android apps may have you thinking that making a mobile app is simple. In reality, however, performance issues can be very complicated, and because performance plays a key role in making sure that your app stays on your users’ list of favorite apps for a long time, every little detail must be given full attention.

In this article, Toptal Freelance Software Engineer Tibor Kaputa shares some tips on how you can optimize some common performance issues and identify some of the bottlenecks in your Android app.

Testing frameworks such as Testify, Ginkgo, and Gomega can streamline testing for Golang applications, however, some of the most efficient and effective tools for testing can be found in Go’s standard libraries. In this article, Toptal developer Gabriel Aszalos covers the basics of testing in Go, from table testing to JSON response assertion.
