Melody Jams may not have made the creators millionaires, but it’s with no doubt an incredibly successful project. Since Melody Jams’ launch Jamie Kosoy and his team overcame massive technical, mental and physical challenges to produce something that is of really high quality. A certain kind of ruthlessness was required with the number of features they wanted to create. They had to go well out of their way to prove their trust to one another. And they had to constantly be making stuff to show each other, rather than just talking about what they were going to make.

If you’ve ever written an iOS app beyond a trivial “Hello world” app with just one screen and a few views, then you might have noticed that a lot of code seems to “naturally” go into view controllers.
Because view controllers in iOS carry many responsibilities and are closely related to the app screens, a lot of code ends up being written in them because it’s just easier and faster that way.

Imagine how great it would be to write your tests only once and run them on different platforms. Writing tests to guarantee bug-free software is not straightforward. However, the underlying technology to build a testing infrastructure should not be an impediment. Appium is a solution that protects you from the heterogeneity of mobile platforms and helps you focus on writing functional tests that can be run independent of platform. In this article, Antonio J. Roa-Valverde will show you how to build your own test automation environment for Android by relying on Appium. Hopefully, this guide will lower the barrier for you to build your own mobile test automation solution.

These frameworks and the whole idea of building mobile apps with JavaScript never appealed to me, though. I always thought, why not just learn Swift/Objective-C or Java and build real apps? That definitely requires a significant amount of learning, but isn’t that what we developers do and should be good at? Quickly learn new languages and frameworks? What’s the point, then? For me, the advantages never outweighed the doubts.

In this article, Ksenia Sternina decided to analyze the physiology of using the interface of Mail.Ru’s Email app; for example, how comfortable is it to use an iPad app in typical positions? The behaviors we studied included tapping buttons while lying down, browsing photos while sitting, swiping, and writing text. Her results revealed a number of purely ergonomic problems that should be taken into account when developing any iPad app. The results are shown here on an iPad layout using a three-color schema. Controls located in the green zone are easily reachable by the average person; the yellow zone is still reachable but not as easily; and the red zone is the most inconvenient location for controls.
