So let's start the tutorial...
1. 3D In The Browser
3D graphics and animation can be truly captivating with all the right details in place: details like lighting and shadows, reflections, and realistic textures. But until now, it has been hard to deliver a compelling 3D experience, particularly over the Internet.
Why? Mostly because creating a 3D experience in games and other applications requires data — lots and lots of data — to display intricate textures and shapes. In the past, these large amounts of data demanded more Internet bandwidth and more computing power than most common systems could handle. All that has changed very recently, and all for the better: browser-based 3D has arrived.
Modern broadband helped solve bandwidth needs. Many homes and offices now have broadband speeds that dwarf the connections of even ten years ago. As a result, it’s possible to send large amounts of data over the Internet — data that is needed to display realistic 3D experiences in the browser. In addition, the computers we use today are so much more powerful than what we had in the past: processors and memory have improved such that even a standard laptop or desktop today can handle the complexity of 3D graphics.
Neither broadband nor raw computing power would matter without substantial advancements in the web browser’s capabilities. Many modern browsers have adopted open web technologies like WebGL and 3D CSS. With these technologies, web developers can create cool 3D effects for their web applications, and we can experience them without needing additional plug-ins. On top of that, many modern browsers now take advantage of a technique known as hardware-acceleration. This means that the browser can use the Graphics Processing Unit, or GPU, to speed up the computations needed to display both 3D and everyday 2D web content.
So why is 3D in the browser a big deal? Because now it joins HTML5, JavaScript and other nifty new technologies in the toolkit that web developers can use to create a powerful new generation of web applications. For users, this means great new ways to visualize the information we find useful, and more fun online with engaging 3D environments and games.
Most importantly, 3D in the browser comes with all the goodness of web apps: you can share, collaborate, and personalize the latest apps with friends all over the world. Definitely more data and fun that everyone can use.
2.SYNCHRONIZING THE BROWSER
So you’re living in “the cloud”: congratulations! You use web apps for email, music, and almost everything. You save critical documents, photos, and files online where you can reach them from any Internet-connected computer, anywhere in the world.
If an 18-wheel truck comes roaring down the road and crushes your laptop to bits, all is not lost. You just find another Internet-connected device and get back to working with all that vital information you so smartly saved online.
In Chrome, for example, sync saves all bookmarks, extensions, preferences and themes to your Google Account. Use any other Internet-connected computer, and all you need to do is fire up Chrome and log in to your Google Account through the browser’s sync feature. Voila! All your favorite browser settings are ready to use on the new machine.
Regardless of how many computers you need to juggle, as long as you have an Internet connection and a modern browser that’s synced to the cloud, you’re all set to go. Even if every one of them gets hit by the proverbial truck.
3.BROWSERS AND PRIVACY
Security and privacy are closely related, but not identica.
Consider the security and privacy of your home: door locks and alarms help protect you from burglars, but curtains and blinds keep
your home life private from passersby.
In the same way, browser security helps protect you from malware, phishing, and other online attacks, while privacy features help keep your browsing private on your computer.
As you browse the web, you generate a similar diary of browser data that is stored locally on your computer: a history of the sites you visit, the cookies sent to your browser, and any files you download. If you’ve asked your browser to remember your passwords or form data, that’s stored on your computer too.
Some of us may not realize that we can clear all this browser data from our computers at any time. It’s easy to do through a browser’s Options or Preferences menu. (The menu differs from browser to browser.) In fact, the latest versions of most modern browsers also offer a “private” or “incognito” mode. For example, in Chrome’s incognito mode, any web page that you view won’t appear in your browsing history. In addition, all new cookies are deleted after you close all the incognito windows that you’ve opened. This mode is especially handy if you share your computer with other people, or if you work on a public computer in your local library or cybercafe.
There’s always a bit of tension between privacy and efficiency. Collecting real-world aggregate data and feedback from users can really help improve products and the user experience. The key is finding a good balance between the two while upholding strong privacy standards.
Here’s an example from the real world: browser cookies. On one hand, with cookies, a website you frequently visit is able to remember contents of your shopping cart, keep you logged in, and deliver a more useful, personalized experience based on your previous visits. On the other hand, allowing browser cookies means that the website is collecting and remembering information about these previous visits. If you wish, you can choose to block cookies at any time. So the next time you’re curious about fine-tuning your browser privacy settings, check out the privacy settings in your browser’s Options or Preferences menu.
