Reactive programming is a programming style where the consumer reacts to the data as it comes in. Asynchronous programming is also called reactive programming. In reactive a programming observables are allowed to propagate event changes to registered observers. "The Observer pattern has done right. ReactiveX is a combination of the best ideas from the Observer pattern, the Iterator pattern, and functional programming." Building blocks for RxJava2.x Observables : Representing sources of data Subscribers (or observers) : Listens to the observables Methods : A set of methods for modifying and composing the data An observable emits items; a subscriber consumes those items. Observables : As mentioned above Observables are the sources for the data. Observable objects that emit a stream of data and then terminate. It can terminate either successfully or with an error. Subscribers : A subscriber objects that subscribe to Observables. An Observer receives a...

More than 1 billion smartphones and 179 billion mobile applications downloaded per year, mobile development is certainly one of the innovative and rapidly growing sector. The mobile application market is arguably dominated by Google apps (Gmail, Maps, Search), Social media (Facebook, Instagram, Twitter, Youtube) and Gaming apps (Angry birds, Temple Run).

Users often avoid downloading apps that seem too large, particularly in emerging markets where devices connect to often-spotty 2G and 3G networks or work on pay-by-the-byte plans. This article describes how to reduce your app's APK size, which enables more users to download your app. Understand the APK Structure Before discussing how to reduce the size of your app, it's helpful to understand the structure of an app's APK. An APK file consists of a ZIP archive that contains all the files that comprise your app. These files include Java class files, resource files, and a file containing compiled resources. An APK contains the following directories: META-INF/:   Contains the CERT.SF and CERT.RSA signature files, as well as the  MANIFEST.MF  manifest file. assets/:   Contains the app's assets, which the app can retrieve using an AssetManager object. res/:   Contains resources that aren't compiled into resources.arsc. lib/:   Contains the co...

What is Cognitive Computing ? Cognitive computing is the simulation of human thought processes in a computerized model. Cognitive computing involves self-learning systems that use data mining, pattern recognition and natural language processing to mimic the way the human brain works. The goals of users evolve as they learn more and redefine their objectives. To respond to the fluid nature of users’ understanding of their problems, the cognitive computing system offers a synthesis not just of information sources but of influences, contexts, and insights. To do this, systems often need to weigh conflicting evidence and suggest an answer that is “best” rather than “right”. Cognitive computing systems make context computable. They identify and extract context features such as hour, location, task, history or profile to present an information set that is appropriate for an individual or for a dependent application engaged in a specific process at a specific time and...

Kotlin is a statically-typed programming language primarily developed by the team of JetBrains that runs on the Java Virtual Machine and also can be compiled to JavaScript source code or uses the LLVM compiler infrastructure. It's a modern programming language. Development lead Andrey Breslav has said that Kotlin is designed to be an industrial-strength object-oriented language, and a "better language" than Java, but still be fully interoperable with Java code, allowing companies to make a gradual migration from Java to Kotlin. Kotlin can be adopted for both sides of development backend and front end. One of the obvious applications of Kotlin is Android development. Android has announced Kotlin as it's official language in Google I/O 2017. Why I should adopt Kotlin : Although Java is one of the world's most widely used programming languages and is pretty much the official language for Android development, there are many reasons why Java might not always ...
