NEW TECH UPDATES

  Introduction Let’s Encrypt is a Certificate Authority (CA) that provides an easy way to obtain and install free  TLS/SSL certificates , thereby enabling encrypted HTTPS on web servers. It simplifies the process by providing a software client, Certbot, that attempts to automate most (if not all) of the required steps. Currently, the entire process of obtaining and installing a certificate is fully automated on both Apache and Nginx. In this tutorial, you will use Certbot to obtain a free SSL certificate for Apache on Ubuntu 18.04 and set up your certificate to renew automatically. This tutorial will use a separate Apache virtual host file instead of the default configuration file.  We recommend  creating new Apache virtual host files for each domain because it helps to avoid common mistakes and maintains the default files as a fallback configuration. Prerequisites To follow this tutorial, you will need: One Ubuntu 18.04 server set up by following this  initial server setup for Ubuntu

NW.js , previously known as node-webkit, is among the community’s favorite Electron alternatives for native application development. Like its competitor, NW.js also enables the easy setup of cross-platform desktop applications simply by using the core trio of HTML, CSS, and JavaScript. You code as if you’re creating any ordinary web application with your favorite tools (React, Angular, Less, webpack, etc.), and in the end, NW.js takes care of translating everything from the web techs to native ones. Many apps have adopted NW.js  already as their hybrid development framework. And all this is possible due to Chromium, the same open source browser owned by Google that powers not only the company’s web browser, but also dozens of other dependent projects out there. Apart from that, NW.js offers a range of great integrations, including native OS-based hardware and file system access, integration with the shell, and many more. In this article, I’m going to walk you through the first steps to
