    • Dynamic CDN for Low Latency WebRTC Streaming


        Having analyzed earlier the capacity of standard server configurations in Digital Ocean in terms of WebRTC streaming, we have noticed that one server can cover up to 2000 viewers. In real life, cases when one server is insufficient are not uncommon.


        Assume gambling amateurs in Germany are watching real-time horse races in Australia. Given that horse races are not only a sports game but also imply big gains on condition that field bets are made at the right time, the video has to be delivered with lowest possible latency.


        Another example: A global corporation, one of FCMG market leaders with subsidiaries in Europe, Russia and Southeast Asia, is organizing sales manager training webinars with live streaming from the headquarters in the Mediterranean. The viewers must be able to see and hear the presenter in real time.

          • Python for AI: A match made in heaven

              The artificial intelligence global market is expected to reach $190 billion by 2025. The bright future of this technology allures every entrepreneur. In fact, when we think about the technologies that are going to rule in the future, the one name that comes to our minds is ~ Artificial intelligence.

              AI along with its subsets like machine learning and deep learning is making such things possible which were unimaginable by humankind a few years back. It is affecting the realities and sometimes changing reality completely.



              The power of AI is well acknowledged by businesses as 84% of respondents in a study voted that they believe artificial intelligence will allow them to enjoy a competitive edge over competitors.

              Although entrepreneurs have an idea about AI but what most of them lack is proper implementation. The use of optimum programming tools for a complex technology like AI can create wonders for the world of business.

              Every custom web developer knows that a python is an apt tool for building AI-enabled -applications. The language has been used to create 126,424 websites so far. Since its launch in the late 1980s, python has seen remarkable growth not only in users but in applications too.

              Python is the favorite language for software developers to create applications that have artificial intelligence, machine learning, etc features embedded in them. But there are reasons behind everything.

              This blog is written with the intent to unveil these reasons. Let’s explore why python is extensively used in AI-enabled software development services.

              Understandable RayTracing in 256 lines of bare C++


              This is another chapter from my brief course of lectures on computer graphics. This time we are talking about the ray tracing. As usual, I try to avoid third-party libraries, as I believe that it makes students check what's happenning under the hood. Also check the tinykaboom project.


              There are plenty of raytracing articles on the web; however the problem is that almost all of them show finished software that can be quite difficult to understand. Take, for example, the very famous businness card ray tracer challenge. It produces very impressive programs, but it's very difficult to understand how this works. Rather than showing that I can do renders, I want to tell you in detail how you can do it by yourself.


              Note: It makes no sense just to look at my code, nor just to read this article with a cup of tea in hand. This article is designed for you to take up the keyboard and implement your own rendering engine. It will surely be better than mine. At the very least change the programming language!


              So, the goal for today is to learn how to render such images:

            • Use AI in marketing: Let’s get into the customers' mind

              “Instead of using technology to automate processes, think about using technology to enhance human interaction.” ~ Tony Zambito, Lead authority in Buyer Personas.

              Do you know ~ according to research, 93% of customers make purchase decisions based on visual appearance. Visual elements of your brand are the key deciding factors for a majority of potential customers.

              Your logo, website colors, chatbot texts, etc all have an impact on the psychology of people who come across them. Some colors or features attract them and some make them leave your website instantly.

              In this era, interactive features with the help of technologies like Artificial intelligence are enhancing such effects. AI has the power to add interactive elements to your presentation. This creates a connection between your company and its customers.

            • Install Powershell Module from Github Repository

              Hi there!

              The latest years Powershell started expansion to other platforms and now works on Windows, Linux, and MacOS (I even managed to start it on raspberry Pi Debian distro).

              And nowadays the main way for installing modules is PowerShell Gallery but in some situations, it still convenient to install modules directly from the source (the main reason — the main PowerShell modules repo configured to MyGet or NugetServer).

              And it can be painful to install Module from GitHub — you should download archive, find modules folder extract archive content and then copy module folder to the Powershell Profile directory.

              Moreover — people like me don't want to create a separate repository for each module (yes, I like the Release-Flow approach) so download and extract only the modules you are like -it even more difficult.

            • How To Implement JavaScript Utility Functions Using Reduce?



                When it comes to code in JavaScript, developers found reduce function as one of the toughest concepts to crack. According to Wikipedia, Reduce has multiple names viz. Accumulate, Fold, Compress and Aggregate. These names clearly indicate the meaning & working of reduce function. The idea behind this is to break down a structure into a single value. Hence, Reduce can be defined as a function which converts a list into any data type.

                For example, you can reduce an array [5,4,3,2,1] into the value 15 by just adding them.

                Reduce function keeps developers away from using loop in order to fold a list into a single value.

                In this blog, you will learn ways to implement well-known functions using reduce as already done by developers in top software development company.

                I have listed out 10 JavaScript utility functions recreated using reduce function. So, check out below these functions:-

                • Map


                Parameters used


                array (to transform list of items), transform Function (is a function used to run on each element)

                Working


                By using the given transformFunction, each element in the given array get transformed and returns new array of items.

                How to implement?


                const map = (transformFunction, array1) =>
                  array1.reduce((newArray1, xyz) => 
                {
                	newArray1.push(transformFunction(xyz));
                
                	return newArray1;
                  }, 
                []
                );
                

                Use case:


                const double = (x) => x * 2;
                const reverseString = (string) =>
                  string
                	.split('')
                	.reverse()
                	.join('');
                
                map(double, [200, 300, 400]);
                
                Output: [400, 600, 800]
                
                map(reverseString, ['Hello Alka', 'I love cooking']);
                // ['alkA olleH', ‘gnikooc evol I']

                  It's no secret I dig WSL (Windows Subsystem for Linux) and now that WSL2 is available in Windows Insiders Slow it's a great time to really explore the options that are available. What I'm finding is so interesting about WSL and how it relates to the Windows system around it is how you can cleanly move data between worlds. This isn't an experience you can easily have with full virtual machines, and it speaks to the tight integration of Linux and Windows.

                • Why 3D Printing Will Change the World?

                    image

                    1984, Orwell’s prophetic year of Big Brother, saw the release of the Mac which broke the idea that centralised control could ever be what it was before. That year also saw the first workable prototype for a 3D printer. Built by Charles Hull, the technology was then known as stereolithography. We know it as 3D printing, and that’s a term that covers a variety of different processes which may revolutionise all stages of the global manufacturing and distributing process. In that very science-fictional year, Hull set off a revolution that is only now seeing fruition. 3D printing continues to threaten the social and economic structures which preceded it. When we speak about 3D printing, we’re speaking of a general technique of successive printing layers to form a three-dimensional object at the end. From powder to paper to human tissue, these thin membranes are laid down like the construction of a plaster mask. From that simple concept, the 3D printer offers the reverse of Ford’s mass production revolution. Printing one item is now as cost-effective in some cases as manufacturing a thousand items in the traditional way.

                    The computer powers 3d printing with printable files known as STLs, guiding the printers themselves as they construct, from the ground up, plastic homunculi that would awe medieval alchemists. It’s not quite the replicator from Star Trek, but it’s in the same Galaxy Class Starship.

                    Our 3D printing future, however, isn’t liable to look like the utopian ideals Gene Roddenberry envisioned. Instead, we will see both positive and negative outcomes from these machines as the world finds ways to employ the emergent technology.

                            There are numerous benefits provided by blockchain technology for sports betting software. The nine key benefits are detailed below.

                            Security of Blockchain

                            When this technology is integrated into sports betting software, there is a permanent and unchangeable record in the transaction ledger providing transparency. Sportsbooks must be certain their betting data is delivered safely with all bets resolved correctly and quickly. This technology provides significantly better protection through the use of smart contracts. Decentralized actors handle the wagers with the smart contracts being executed automatically. Publicly written data cannot be altered. The complex system of the past is simplified and performed for much less than the traditional costs. Blockchain Development Services, Blockchain Solutions are paramount not only in sports betting but every aspect of the new business world. Blockchain technology experts integrate cryptocurrency payment solutions, program smart contracts, and engineer blockchain networks and apps.

                            This provides better protection, flawless bet execution, enhanced data security, and complete information transparency. The use of cryptocurrency significantly decreases the fees for payment processing. This reduces the margins for the sportsbook while offering players an increased chance to win. Once the bets have been resolved with a smart contract, the funds will be in the wallet of the better for almost immediate withdrawal. Any issues for even larger amounts are eliminated due to cryptocurrency payouts.

                              In June, we heard about SwiftUI for the first time — a totally new way of creating and working with UI elements in iOS and macOS (also iPadOS) apps. It felt like Christmas in the summer. It's new, it's declarative, it's sexy! And now, just a few weeks after iOS 13 has been released, we can start to use SwiftUI in all our projects. Let's learn how to use this amazing tool that Apple gave us, to create the classic Tinder-esque Swipe Cards.

                              In this article, I would like to show you how to achieve a Tinder-like card view and behavior (swipe to action), with just a few lines of code.

                              To achieve this, we need to do the following things, in order:

                              • Create UserView
