RUST: Numeric Data Types

You must be wondering what is so special about numeric data types in RUST, that we are focusing on them so much, definitely, you will get to know after finishing this blog. Generally, other programming languages follow short, int, float, long, double etc as numeric data types as per their storage size and capacity while in RUST numeric data type are like : i[size_in_bits] or u[size_in_bits]  Here, i Continue Reading

RUST: Quick Start & Exploring Cargo

This blog will guide you through the brief introduction to RUST, installation, uninstallation, version updating and quick start with its own build tool CARGO. RUST – safe, concurrent, and practical language, much similar to C++ (syntactically) supports functional as well as imperative-procedural paradigms. Setting up RUST in your system: For Linux or Mac: It’s quick and easy to install and setup your system for RUST Continue Reading

Concepts of CQRS

In the previous blog, we have learnt what Event Sourcing is. Moving forward, we will dive into the concepts of CQRS, understanding its meaning, why is it required and its advantages. CQRS Pattern CQRS stands for Command Query Responsibility Segregation. As the name suggests, we split the application in two parts: Command-Side and Query-Side. Now one will ask what this command and query means? Okay, Continue Reading

Introduction to Event Sourcing

Have you ever come across the terms Event Sourcing and CQRS? This blog is a good start to gain basic knowledge about the two. Here, we will learn what is Event Sourcing? And what are the benefits of having an event sourced application? CQRS will be covered in the next blog. What is Event Sourcing? Event sourcing is the practice of capturing all changes as Continue Reading

Scorex: A Modular Blockchain, Scala Framework

Scorex is an open-source project written in Scala with loosely coupled and pluggable components. Scorex provides many abstractions for which you have to provide concrete implementations to make the Blockchain as per your requirements on the top of Scorex. It is backed by IOHK, a technology company based in Hong Kong. Scorex is still experimental and raw. It appears to be in an early stage of development. All the Continue Reading

Introduction to Hyperledger Sawtooth

Hyperledger Sawtooth is Hyperledger’s open-source blockchain platform, following closely on Hyperledger Fabric. It is an enterprise distributed ledger proposed by Intel and was one of the first projects to join Linux Foundation’s Hyperledger umbrella. This platform is modular, scalable, with an innovative consensus model, has unique support for permissioned and permissionless infrastructure and the potential for incredibly large network sizes.

Back2Basics: The Magic of Implicits

Implicit System is one of Scala’s language greatest feature with the help of which we can write concise code. The implicit system in Scala allows the compiler to adjust code using a well-defined lookup mechanism. In this post, we will try to understand how Scala’s implicit work magically. Scala provides an implicit keyword that can be used in two ways: method or variable definitions, and method parameter lists. Continue Reading

Amazon ES – setting up the cluster! #1

Amazon Web Services (AWS) is a cloud services platform, providing compute power, database storage, content delivery, security options and other functionality to allow businesses to build sophisticated applications with increased flexibility, scalability and reliability. Amazon Elasticsearch is one of the services provided by AWS. Amazon Elasticsearch Service, also called Amazon ES, is a managed service that makes it easy to create a domain, deploy, operate, Continue Reading

Back2Basics: Type Erasure in Scala

Scala has a really strong type system. Scala’s static type system is listed as one of its strong points. But even though Scala’s type system is theoretically very strong, in practice some type-related features are weakened by the restrictions and limitations of its runtime environment, i.e. Type Erasure. So, what is type erasure? Type erasure refers to the runtime encoding of parameterized classes in Scala. Continue Reading

GraphQL – The Better REST

Over the past few years, the REST has become a de-facto architecture for the web services, which emphasize to communicate through the textual data. The user is given a URI of the resource and user can perform various operations (GET, POST, DELETE etc) defined on that address, as simple as that. There are several architectural points that reflect upon the ideology of the REST. These points Continue Reading

Exploring JEST: Java HTTP REST Client

Elasticsearch is a real-time distributed and open source full-text search and analytics engine. To integrate Elasticsearch to our application, we need to use an API. Elasticsearch gives us two ways, REST APIs, and Native clients. It’s easy to get confused about all the different ways to connect to Elasticsearch and why one of them should be preferred over the other. Available Elasticsearch clients are: Node Continue Reading

Apache Ignite is an in-memory computing platform that is durable strongly consistent and highly available with powerful SQL, key value and processing APIs. Features : Durable Memory : Apache Ignite is based on the Durable Memory architecture that allows Continue Reading

Introduction to GraphQL – A Query Language for APIs

GraphQL is an API standard that provides a more efficient, powerful and flexible alternative to REST. It was created by Facebook in 2012 and was open-sourced in 2015 and is now maintained by a large community of companies and individuals from all over the world. GraphQL is just a specification, meaning it’s just a set of rules defined in a document. GraphQL is a query language designed Continue Reading
