Types of VPN

A VPN is a service that creates a private tunnel within a public connection (e.g. the internet), so that users can send and receive information safely and securely. There are different types of VPN. A user may want to connect to a VPN to stream a movie that is unavailable in their current location or maybe they want to connect to a company network while they are at home and working.

Ray Tracing

Ray Tracing is a graphic rendering method that draws an image of a scene by considering how light moves in the real world. However, in this method, the processes follow the opposite path in the real world. In the real world, light rays emerge from a light source and illuminate objects. According to Nvidia, the most commonly used ray tracing algorithm is BVH (Bounding Volume Hierarchy) Traversal. It uses the DirectX Raytracing API and accelerates Nvidia's RT cores. Optimizing the calculation of the intersection of rays and polygons is critical. When we consider a scene with hundreds of objects, we have thousands of potential polygons and we try to calculate which polygons the ray intersects. This normally creates a search problem and takes a very long time. BVH, on the other hand, speeds up this process by creating a tree of objects in which each object is enclosed in a box.

The Art of Evolving

How do you rate yourself compared to last year? Are you doing well? Are you slipping down? Whatever you feel about your journey, one thing you have to admit is that it’s “evolving”. You are not the same person anymore whether it’s good or bad evolution is taking place inside you.

Docker In Action

In this section of my Docker series, I’m going to work through a typical development workflow. Please don’t try to memorize anything in this blog, because all I want you to see is the big picture. So I’m going to create a folder called hello-docker in my Desktop directory, inside that folder, I will create two files: **1. app.js** **2. Dockerfile**

Introduction to VPN

VPN stands for the **Virtual Private Network.** A virtual private network (VPN) is a technology that creates a safe and encrypted connection over a less secure network, such as the internet. A Virtual Private Network is a way to extend a private network using a public network such as the internet. In short, users can be part of a local network sitting at a remote location. ## Why use VPN? Imagine a scenario, -> You are living in the U.S. and traveling to India for some reason. While reaching India you want to watch a movie on Netflix. But the movie is exclusive to the U.S. -> You open Netflix on the TV and search the movie name but the movie is not shown.

Gamification Series -2- Flow Theory

Gamification, as I mentioned in [last week’s blog](https://www.archisacademy.com/blogs/gamification-series-1), is an effective method to build desired behavior change in education as well as in the business world. However, in order to do that, people -or the users let’s say- should have enough motivation, not only at the beginning stage of the process but also till the end of it. In other words, they should **“be in the flow”.** **Mihaly Csikszentmihalyi** defines flow theory as a mental state and feeling, where a person concentrates on a clear goal without outer disruptions and enjoys what he/she is doing. The theory also suggests that an activity should be hard enough to challenge the person, but also not so hard to discourage them. This may sound familiar to those who are involved in educational sciences as **Krashen** proposed his input hypothesis (i+1) in a quite similar fashion.
