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 […]
Swift 3 is the first update since Apple announced Swift would be going open-source, and is packed with new features based on community direction. When converting to Swift 3, you’ll notice that practically every file needs changes! That’s largely because, all the Cocoa API names have changed. Or to be more precise, the API is […]
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 […]
More and more Android apps provide video editing based features. This library is not a complete wrapper for the most recent Mp4Parser library. However, it provides a few useful features that are usually used by these apps. If it does fit your application’s needs, feel free to implement those features based on the current implementation. The […]
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). […]
Tons of document formats using XML syntax had been developed, like RSS, Atom, SOAP and XHTML, so it’s good to know, how to work with them. If you are not familiar with XML, it’s basically a precisely formatted text or string, which can be parsed into an array of objects containing the precious information.
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.
Android contains several APIs that hold resources back. They need to be released before closing the current Activity or any other UI part. Doing things the old way, you are responsible for releasing these resources at the end of each activity. With complex tasks, it becomes quite hard to keep track of all of these resources. It is even more complicated when you use them in asynchronous tasks. A small programming overhead will eliminate this problem by replacing the async tasks with Rx streams and scheduling them on the background threads. So, Rx wrappers will ease thread handling. Here is how I use Rx wrappers to make them as awesome as possible:
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.
