The story Mondays are always a unique mixture of a new beginning and unexpected surprises in every office. Sometimes you find a solution for a long-standing problem, but you never know what awaits you in your mailbox after a long, unclouded weekend. The Monday morning, on which my story begins, is a good example for […]

Sure it’s not Instagram filters; Couchbase filters are to be created here: What is Couchbase? Couchbase Server is a NoSQL document database with a distributed architecture for performance, scalability, and availability. It enables developers to build applications easier and faster by leveraging the power of SQL with the flexibility of JSON. http://www.couchbase.com/nosql-databases/couchbase-server Why do you […]
a.k.a. I WANT THEM TO LEARN AND NOT JUST PLAY MINECRAFT ALL DAY I’m writing my post mainly to moderately desperate parents seeing their children in front of computer screens flooded with seemingly useless games. I’m also writing my post to excited older brothers/older sisters/uncles/aunts whose lives’ are devoted (~committed, ha ha.) to making the world […]
Being on the verge of employment for me was a rather scary situation as a wannabe developer. There were so many doubts in my mind – most of which in retrospect were absolutely irrational. As of now, I’ve been working at Wanari for 3 months. Here I will write about my fears as a student, […]
Generally, microservices are great. In theory, they are divided up well, they are scalable, and they can be maintained easily. With one word, they are great. However, there are some challenges you will most probably encounter when working with microservices. This post will help you get a grip on the world of microservice-development, its challenges, and […]
What is WebSocket? When should I use it? WebSocket is an amazingly fast, easy to use and full-duplex way to communicate between client and server. WebSocket is recommended if you want a fast real-time application like a bid application, or a real time poker game. It’s easy to broadcast messages between users (or just send […]
So, the Java8 Optional has two really cool (and similar) functions: the orElse() and the orElseGet(). If we quickly read the javadoc for each, we will only see a small difference; one of them has a T type as a parameter and the other has a function which must return with T (as a parameter). […]
When we started to you use Slick for the first time, we had no clue on how to set up our code for multiple database types in our Play! application.
This post will tell you how we use a simple YAML file to insert the initial data (like roles, privileges, admin user, and all the other necessary data) into our database. We use Play! Framework (Java) with Hibernate. The important part is how we make Objects from the YAML description using SnakeYAML (Play framework’s integrated YAML parser) though.
I’ll give you some tricks on how to use YAML easily in order to create the initial data for your application.
I was working on a Play! Framework project and I was wondering why our whole API was available in one piece. It got me thinking whether there is a way to hide at least some parts of the API from the clients. Precisely because some of the clients didn’t have the privilege/permission to execute given operations, e.g. visiting restricted pages. I thought there should be a way to hide at least the operations that are on these restricted pages. I’ve found a way to do so and below it is.
