Social media surrounds us, so it’s not unusual for applications to require some kind of social media integration. The most common issigning in with Facebook, Twitter, or another service. Users expect to be able to log in with different social accounts. So, applications meet these expectations by offering external login options. Let’s take a look at this functionality and investigate how to merge users’ accounts – specifically, we’ll consider the situation when people use several methods to log in.

Handling user registration and authentication isn’t an easy task. Both users and developers understand this. Users have to select and remember another username and password (taking into account different password policies, of course). A developer’s responsibility is to make this process secure and to properly protect the user’s data. So it’s no surprise that logging in with one account – Facebook or Google, for example – is extremely popular.

Before writing this article, I talked to a group of software engineers who use Hibernate on a daily basis in their work. Some of them work for small companies (up to 20 developers on site) while others are employed in corporations known world-wide that employ over 100,000 IT professionals. This gave me an insight into how development with Hibernate is organized in different companies. There are several approaches to creating SQL scripts and Hibernate O/R Mapping classes.

What is Gradle? Gradle is an open source build automation system. It can automate the building, testing, publishing, deployment and more of software packages or other types of projects such as generated static websites, generated documentation or indeed anything else. Learn more about what makes Gradle a compelling choice for build automation. One of the exciting moments in a programmer’s life is to leave legacy code behind and have fun with some new, fresh and cool tools.

In this article I’m going to show you how to design SQLAlchemy models using Vertabelo, an online tool for visual database design, and our code generator. SQLAlchemy is propably the most advanced and well engineered OR/M for Python, while Vertabelo is a database design tool that works in a web browser. The Vertabelo code generator is an pythonic script called vertabelo-sqlalchemy. As you can see, the script is open source and hosted on GitHub.
