We Are Developers. That’s the claim and motto of the largest developer event in Europe.

And since we at Usersnap are developers, too, we put on our best suits (well, just kidding 😉) and attended this year’s largest developer event, right in Vienna.

Together with 3.800 other developers from all over Europe we were pretty impressed by the organizers work and listened closely to speakers like John Romero, Joel Spolsky, and Håkon Wium Lie.

In this article, we’d like to share a few conference highlights from this year.

More and more web applications are being developed these days, and with each line of code being written, the potential for bugs arises.

Generally speaking, the costs of fixing bugs increase exponentially the later you find them. The Systems Sciences Institute at IBM found that “the cost to fix an error found after product release was four to five times as much as one uncovered during design, and up to 100 times more than one identified in the maintenance phase”. And a study by the University of Cambridge found that software bugs cause economic damage of $312 billion per year worldwide.

These numbers highlight the importance of finding bugs as early as possible and to thoroughly test an application before it is released.

That is where web application testing comes in. Web application testing usually consists of multiple steps that ensure that an application is fully functional and runs smoothly and securely. It is an essential part of web development and ensures that an app is running properly before its release.

We put together a 6-step guide, which should give you an overview of what kind of tests to run to test your app.

Let’s get started!

Meet the CTO is a new series about CTOs, their daily lives, roles, and responsibilities. This week, we talk to Jan Varljen, CTO of Productive.

Jan shares his story of starting out as a web developer at one of the largest agencies in Croatia. As the CTO of Productive.io, Jan is now managing a team of developers building the next generation of agency software.

Flat design can be seen as the more sophisticated cousin of minimalism —all design elements are centered on the idea of simplicity. However, the simplicity of flat design is hard to achieve — everything should be designed with the same goal in mind to create a cohesive visual and functional design.

Let’s look at what you can do to make flat design works for your users.

Josef is co-founder & CPO at Usersnap and runs the development- and product-side. Before founding Usersnap Josef worked on various tech- and web projects, starting his first business right out of high school. Being co-founder and CPO we sat down with Josef to talk about his life and daily habits.

Meet the team and community is a series introducing our team and the Usersnap community. You’ll get new insights about the life and work of us Usersnapians and might discover new glimpses on the latest technologies.

Visibility of system status is one of the most important rules of UI design. The goal behind this rule is pretty obvious — to minimize user tension you should provide feedback to the user about what is happening with the app within a reasonable amount of time. Don’t keep the users guessing — tell the user what’s happening. And one of the most common forms of such feedback is a progress indicator.

In this article, we’ll give you an overview of the main types of progress indicators and the use cases for them.
