Threats in Cyberspace

We live in a digital world where life beyond the web is too hard to think of. Our personal lives, work lives, and finances all in the process tend toward the world of the internet, mobile computing, and electronic media. Humans are just one click away to attain knowledge about every little thing. Smartphones and Laptops seem to be a part of daily life, internet usage also expanded. Unfortunately, the overall aspects make us more vulnerable than ever to malicious attacks, invasions of privacy, fraud, and other unpleasantries. In March 2013, the nation’s top intelligence officials cautioned that cyber-attacks and digital spying are the top threat to national security, eclipsing even terrorism. Reports suggest that by the year 2021, the total loss in the global economy would be US$6 million due to cyber-attacks and cybercrime would cost $10.5 Trillion annually by 2025.

GitHub Workflow

Git and GitHub is a must for any developer. At some point of your path, especially if it is related to the software industry, you will definitely hear of “Git” and “GitHub”. Even if you haven’t heard about them, I will briefly touch on what those terms are. After that, I’ll go into further details of gitflow which is a branching strategy that helps management of your code. Git is a version control system which tracks your code for any changes and records it. So it gives an opportunity to revert the changes you made mistakenly, or make a version update after fixing the issue. Beside that, it is possible to collaborate on the project with team members as they can also contribute to the source. GitHub cannot be imagined without git, so it is the main component of the website. It hosts “more than 190 million repositories (including at least 28 million public repositories)”. Those repositories may consist of the source code of a software , or even book contents. They provide some features such as pull requests and task management.

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**
