This blog walks through the packaging of simple python project. Lets add the necessary files and structure to create the package, then build the package and upload it to python package index ( PyPI ). Let suppose your project (sample_pkg) is created in the root directory. Mandatory Basic Directory Structure of your sample project should be: /sample_pkg /sample_pkg __init__.py project util and source code files Continue Reading
Hi Everyone, In our previous blogs, we have discussed several Structural design patterns i.e., Decorator design pattern, Adapter design pattern and Proxy design pattern. In this blog, we will be discussing Facade Design pattern and will try to implement it in Scala. Problem Statement: We recently had a tour to Udaipur from our office and to organize it, we inquired a travel agency and asked Continue Reading
Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell the browser to let a web application running at one origin(domain) have permission to access selected resources from a server at a different origin. A web application makes a cross-origin HTTP request when it requests a resource that has a different origin (domain, protocol, and port) than its own origin. An Continue Reading
What is Protocol Buffers? Protocol buffers are a flexible, efficient, automated mechanism for serializing structured data – think XML, but smaller, faster, and simpler. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages. Continue Reading
In the previous blog MEAN Stack: Introduction – Part 1, I have given a brief introduction of MEAN Stack and all the technologies used in it. In this blog, I’ll be discussing the installation of all the technologies one by one for Ubuntu. MongoDB: MongoDB is an open-source document database that provides high performance, high availability, and automatic scaling. The installation of MongoDB Community Edition Continue Reading
In Rust, Smart Pointers are not only pointers but a data structure as well. They are also available in many other languages, but their origin lies in c++. Smart pointers are generally implemented through structs. Following are the types of Smart Pointer in rust. 1. Box The box is the most simple smart pointer which enables recursive types. At compile time rust compiler wants to Continue Reading
Both Lagom and Kubernetes are gaining popularity quite fast. Lagom is an open source framework for building reactive microservice systems in Java/Scala. And, Kubernetes (or K8s in short) is an open-source system for automating deployment, scaling, and management of containerized applications. Together they make an excellent stack for developing Reactive microservices of production grade. We have already seen a lot of blogs on Lagom on this Continue Reading
D3 (Data-Driven Documents or D3.js) is a JavaScript library for visualizing data using web standards. It is an open-source JavaScript library developed by Mike Bostock to create custom interactive data visualizations in the web browser using SVG, HTML, and CSS. giving you the full capabilities of modern browsers and the freedom to design the right visual interface for your data.
Hey folks, in this blog I am going to explain how can you schedule jobs that you want to repeat over a certain period of time with the help of Akka Scheduler. Suppose you have a use-case in which you want some cleaning background process to run a cleanup-repository method to delete records after a fixed interval of time, then look nowhere else because Akka scheduler Continue Reading
Dotty is the new scala compiler that 2.13 Scala release will be using. It is based on the DOT in its internal structure. The calculus used in Dotty is same as that of DOT. Dotty is a faster compiler than the scala compiler that Scala 2 uses. In this blog, I’ll be discussing the advantages of dotty, its architecture and the features that have been Continue Reading
We have already explored the introduction to FP in my previous blog. Once you get into FP, you’ll quickly start hearing the terms lambda and lambda calculus. Lambda: Lambda is basically just a symbol represented as λ that Alonzo Church chose when he first defined the concept of a function. In modern functional programming, lambda means “anonymous function“. Calculus: Calculus is means a formal system in mathematical logic for expressing Continue Reading
Once a wise man said, “A product that cannot be tested is flawed”.It also applicable in software development as well, Let me re-figure it – “A software that cannot be tested is flawed”. The testing of software acts as an important role in every software development approach, it improves the quality and value of the software against the client. In an era of automation, I’m introducing Continue Reading
As a niche consulting and development organization we end up in a lot of enterprises who would like to modernize, would like to build web-scale products but they are not ready to look beyond Spring. It is a strongly debated topic and there are reasons for still going the Spring way but the reasons are less and less as we go ahead. For starters, this Continue Reading
