Virtual Reality Casino Games Could be the Future of VR

Here are some reasons why Virtual Reality Casino Games could be future of VR

The hot topic among tech companies and enthusiasts in 2016 was undoubtedly virtual reality. With casual consumers being exposed to a new world of gaming opportunities for the first time as Oculus Rift, HTC Vive and PlayStation VR began shipping their products, the mood among analysts and experts was buoyant. In fact, if a 2016 report by Digi-Capital holds any weight, then we could see virtual reality (VR) and its tech cousin augmented reality (AR) become a $120 billion industry by 2020.

Although there’s a long way to go until 2020, we can already see signs of the VR industry evolving beyond the already-“traditional” headsets. For example, back in November 2016 we brought news of the world’s first VR enabled smartphone. Affectionately known as the Darling VR Smartphone, the device has an in-built camera that allows the user to record 360-degree panoramic scenes that can then be used for VR live streaming.

Online Casino Developers are Already Working on New Ideas

Despite being positioned in an industry that has yet to fully find its feet, major virtual reality developers are already looking towards the future and where the technology could take us. One direction a number of gaming companies look to be heading towards at the moment is VR gambling. Already a sub-sector of the gaming industry as a whole, iGaming has become a $50 billion market since the turn of the millennium. Naturally, alongside growth comes innovation, and the leading software developers are now turning to VR for their next ventures.

Indeed, when you look through a list of online casino software providers, you’ll now see that almost all of the top players are testing VR products. For instance, looking at review site Online-Casino-Canada.ca’s noted software developers, Microgaming stands out as one of the most innovative. According to the review site, this company has been in operation since 1994 and currently offers 600+ online casino games. Using this pedigree and experience, Microgaming has recently moved to push the boundaries of what’s currently possible.

Microgaming VR Roulette was first previewed at ICE Totally Gaming 2016. Housed inside a specially made CRYO Lab, the game combined Oculus Rift headsets with Leap Motion 3D controllers. This cocktail of technology allowed the company to successfully create a virtual casino setting where players could pick up chips, spin a roulette wheel and collect bets. As well as winning the Digital Product of the Year at the Global Gaming Awards, the prototype has inspired other iGaming developers to play with VR.

iGaming Innovations Could Drive the VR Industry Forward

In 2017, another company on the review site’s list, NetEnt, announced the launch of the world’s first VR slot. Taking one of its most popular games, Gonzo’s Quest, the company has redesigned the format to work in a VR setting. Set to be rolled out at some point in 2017, the game features a 360-degree environment, interactive characters, and jackpots that rain down from the sky.

Although these products are still in a developmental stage, it’s certainly a taste of things to come. In fact, a study by Juniper suggests that VR gambling alone could be worth just under $520 million by 2021. With established operators already testing out new products and mainstream names likes Samsung and Facebook also eyeing up the idea of VR betting, the industry could grow by 800 percent in the coming years according to Juniper’s analysts.

If this proves to be the case, it would make gambling one of the largest players in the VR industry. Although other entertainment and advertising sectors are likely to play a significant role in the evolution of VR, it seems as though gambling may just be the thing that helps make it a mainstream hit.

Samsung Dropped On-Screen Fingerprint Sensor Feature From Galaxy S8 At Last Minute

 

Samsung Galaxy S8’s Fingerprint Sensor Was A Last Minute Decision

In order to achieve a high screen-to-body ratio, Samsung’s upcoming Galaxy S8 smartphones will not feature a fingerprint sensor on the front but instead would be built into the display, as the flagship device won’t come with a physical home button. Reportedly, the rumor was true, but Samsung ran out of time.

According to a report from The Investor, Samsung and Synaptics, the partner that works on the touch sensor, wanted to create a new feature technology that would have separated the device from the competitors. Samsung poured a lot of money into the development, but Synaptics failed to create the technology needed on time. However, they found that the process was slow and the results were “frustrating”.

As production got closer, Samsung had to make the decision to move the sensor to the back of the smartphone next to the rear-facing camera, as seen in the latest leaked images of the final design.

“With the production imminent, the company had to decide to relocate the fingerprint scanning home button to the back of the device at the last minute,” said a source familiar with the matter.

However, the placement of the fingerprint sensor on the back directly next to the rear-facing camera has been one of the few things that people aren’t happy about. People just don’t seem to like the setup, which requires reaching with the finger to the top of the smartphone, potentially smudging the camera lens in the process. Also, some believe that positioning the fingerprint sensor next to the camera makes it difficult to access it.

The Galaxy S8 is due to be announced on March 29th at an unpacked event in New York City and in London. The device will reportedly come in two sizes: a standard 5.8-inch model and a Galaxy S8 Plus with a 6.2-inch screen. Both devices will offer curved displays and will not have a physical home button beneath the display.

What Is the Best Book for Learning JavaScript?

Best Books To Learn JavaScript

JavaScript is an object-oriented computer programming language commonly used to create interactive effects within web browsers. Over the years, JavaScript has emerged as the go-to language for programmers who want to develop web applications that are more interactive and user-friendly.

JavaScript was first conceived in 1993 in the heady days of Internet Explorer and Netscape Navigator. The then king of browsers, Netscape Navigator founder Marc Andreessen believed that Netscape needed a “glue language” to support HTML that would be easy to use by Web designers and part-time programmers to assemble components such as images and plugins, where the code could be written directly in the Web page mark-up. Also, Bill Gates’ Microsoft Internet Explorer was eating into market share of Netscape Navigator. That is when Brendan Eich, father of JavaScript, was contracted by Netscape Communications to develop a “Scheme for the browser”.

Scheme is a Lisp dialect and, as such, comes with very little syntactic weight. It is dynamic, powerful, and functional in nature. The web needed something of the sort: easy to grasp syntactically; dynamic, to reduce verbosity and speed up development; and powerful. Eich saw a chance to work on something he liked and joined forces.

In 1995, JavaScript was developed under the name Mocha; however, the language was officially called “LiveScript” when it first shipped in beta releases of Netscape Navigator 2.0 in September 1995. But in December, it was renamed JavaScript when it was deployed in the Netscape Navigator 2.0 beta 3.

Eventually, competition from Google’s Chrome, Microsoft’s Internet Explorer and Mozilla’s Firefox saw the end of Netscape Navigator. However, JavaScript has gone on to live to this date powering the way how our webpages look like.

Not to be confused with Java, JavaScript is a high-level, popular, powerful, dynamic, untyped, and interpreted programming language. JavaScript is a scripting language that makes the pages interactive. JavaScript is the most commonly used programming language to create cool websites and games for the web. It derives much of its syntax from The C Language. Through JavaScript, you can add pop-up messages, etc. In recent years, JavaScript has also gained use as the foundation of Node.js, a server technology that among other things enables real-time communication.

So, what is the best book for learning JavaScript? This answer depends on many factors such as, what kind of learner are you? Or where do you find yourself on your learning journey? Or how much time do you have to spend and much more.

In this article, we bring to you the top three JavaScript books that are best according to us.

1. Effective JavaScript

After you have had some basic exposure to JavaScript, “Effective JavaScript” will take you on a guided tour of the language in more depth, showing by example lessons taught by a master programmer seasoned in his craft. Written by David Herman, this book walks through the syntax and semantics of JavaScript that is both charming and hugely insightful; reminders of gotchas complement realistic use cases, paced at a comfortable curve.

Right away, you will be introduced to some of the quirks of JavaScript, from floating point number precision (because JavaScript only has one number type, and it’s a floating point type), to the oddities of type coercions and semicolon insertion. Effective JavaScript is organized around 68 proven approaches for writing better JavaScript, backed by concrete examples. You will learn how to choose the right programming style for each project, manage unanticipated problems, and work more successfully with every facet of JavaScript programming. The rest of the book continues in the same style, exploring best practices for working with functions, objects, arrays, library and API design, and concurrency.

Once you finish the book, you will find that you have gained a strong and comprehensive sense of mastery. This is not a book for those looking for shortcuts; rather it is hard-won experience distilled into a guided tour.

2. Eloquent JavaScript, 2nd Edition

This is the second edition of the great book written by Marijn Haverbeke, which teaches you how to write precise, elegant and practical code.

“A concise and balanced mix of principles and pragmatics. I loved the tutorial-style game-like program development. This book rekindled my earliest joys of programming. Plus, JavaScript!” —Brendan Eich, creator of JavaScript.

It starts off with the basics of programming where you can learn to use variables, control structures, functions, and data structures. As you go deeper, you will dive into the real JavaScript artistry: higher-order functions, closures, and object-oriented programming.

Along the way, you will learn to master basic programming techniques and best practices, use regular expressions to quickly parse and manipulate strings, harness the power of functional and object-oriented programming, gracefully deal with errors and browser incompatibilities, handle browser events and alter the DOM structure. Most importantly, Eloquent JavaScript will teach you to express yourself in code with precision and beauty. After you’ve learned all that, the book will show you how to build an HTML game and some example apps with Node.js.

3. You don’t know JS

You don’t know JS by Kyle Simpson is a series of books that examine the inner workings of the JavaScript language. With the “You Don’t Know JS” book series, you will get a more complete understanding of JavaScript, including complex parts of the language that many experienced JavaScript programmers simply avoid.

The series’ first book, Up & Going, provides the necessary background for those with limited programming experience. By learning the basic building blocks of programming, as well as JavaScript’s core mechanisms, you’ll be prepared to dive into the other, more in-depth books in the series—and be well on your way toward true JavaScript.

With the help of this book, you can learn the essential programming building blocks, including operators, types, variables, conditionals, loops, and functions become familiar with JavaScript’s core mechanisms such as values, function closures and prototypes. Get an overview of other books in the series—and learn why it’s important to understand all parts of JavaScript.

The titles in this series are as follows:

• Up & Going (72 pages)
• Scope & Closures (83 pages)
• This & Object Prototypes (158 pages)
• Types & Grammar (182 pages)
• Async & Performance (280 pages)
• ES6 & Beyond (261 pages)

Each book can be purchased individually and they are all free to read online.

Please note that could be other books on JavaScript that may be better than the ones given above. If you know of a better JavaScript book, do let us know in the comments section below.

எப்போதெல்லாம் தண்ணீர் குடிக்கக்கூடாது என்று தெரியுமா?

பெரும்பாலான பிரச்சனைகளுக்கு தண்ணீர் தீர்வளிக்கும். தண்ணீர் உடலை நீர்ச்சத்துடன் வைத்திருப்பதோடு, அளவுக்கு அதிகமாக சாப்பிடாமலும் தடுக்கும். மேலும் தண்ணீர் அதிகப்படியான கலோரிகளை எரிக்கவும் உதவும்.ஆனால் அந்த நீரைக் குறிப்பிட்ட நேரங்களில் குடிக்கக்கூடாது. உங்களுக்கு எந்த நேரத்தில் நீரைக் குடிப்பது நல்லது, எம்மாதிரியான நேரத்தில் நீரைக் குடிக்கக்கூடாது என்று தெரியாதா? அப்படியெனில் இக்கட்டுரை உங்களுக்கு மிகவும் உபயோகமாக இருக்கும்.சரி, இப்போது ஒருவர் எந்த நேரத்தில் நீரைக் குடிக்கக்கூடாது என்பது குறித்து காண்போம்.

தருணம் #1

ஒருவர் ஏற்கனவே அளவுக்கு அதிகமான நீரைக் குடித்தப் பின், தேவையில்லாமல் நீரைக் குடிக்கக்கூடாது. நீர் உடலுக்கு ஆரோக்கியமானதாக இருக்கலாம். ஆனால் எதுவுமே அளவாக இருந்தால் தான் என்பதை மறக்க வேண்டாம். ஒருவேளை ஒருவர் ஒரே நாளில் அளவுக்கு அதிகமாக நீரைக் குடித்தால், உடலில் உள்ள இயற்கையான உப்பு வெளியேற்றப்பட்டு,பின் அவஸ்தைப்படக்கூடும்.

தருணம் #2

உங்கள் உடலில் நீர்ச்சத்து போதுமானாதாக இல்லாவிட்டால், சிறுநீர் அடர் மஞ்சள் நிறத்தில் வரும். இம்மாதிரியான நேரத்தில் நீரை அதிகம் பருக வேண்டும். ஒருவேளை மஞ்சளாக இல்லாமல், தெளிந்த நிறத்தில் சிறுநீர் வெளியேறினால், உடலில் போதுமான அளவில் நீர்ச்சத்து உள்ளது, நீரை அதிகம் குடிக்க வேண்டிய அவசியம் இல்லை என்று அர்த்தம்.

தருணம் #3

உணவு உண்பதற்கு முன் 1 டம்ளர் நீரைக் குடிப்பதன் மூலம், அளவுக்கு அதிகமாக உணவு உட்கொள்வதைத் தவிர்க்கலாம். ஆனால் உணவுக்கு முன் அல்லது பின் அளவுக்கு அதிகமாக நீரைக் குடித்தால், பின் மிகுந்த அசௌகரியத்தால் அவஸ்தைப்படக்கூடும்.

தருணம் #4

சாதாரண உடற்பயிற்சிக்கு பின் நீரைக் குடிப்பது எவ்வித தவறும் இல்லை. ஆனால் மிகவும் கடுமையான உடற்பயிற்சியை செய்த பின், உடலில் உள்ள எலக்ட்டோலைட்டுக்கள் வியர்வை மூலமாக வெளியேறியிருக்கும். இந்நேரத்தில் நீரைக் குடிப்பது நல்லதல்ல. மாறாக, இளநீரைக் குடிப்பதே மிகவும் நல்லது.

தருணம் #5

தற்போது தாகத்தை தணிப்பதற்கு என்று ஏராளமான குளிர்பானங்கள் விற்கப்படுகின்றன. ஆனால் எவ்வளவு தாகம் எடுத்தாலும், நீரைக் குடியுங்கள். மாறாக குளிர்பானங்களைப் பருகினால், அது உங்கள் பசியை அதிகமாக தூண்டிவிடும். மேலும் குளிர்பானங்களில் கலோரிகள் அதிகம் இருப்பதால், உடல் பருமனடையவும் செய்யும்.
