what is html5?

Hyper Text Markup Language
An W3C/ WHATWG Standard
Previous version: HTML 4.01 (1999)

HTML5 is a family of technologies and specifications:
  • HTML: structure
  • CSS: styles
  • Javascript: interactivity 

Specially designed to:
  • Replace both HTML 4, XHTML, and the HTML DOM Level 2
  • Deliver rich content without the need for additional plugins
  • Be Cross-Platform

html5 - What people say

“I think the biggest mistake that we made, as a company, is betting too much on HTML5 as opposed to native… Because it just wasn't there…”  (Mark Zuckerberg, September 2012)
“Hybrid mobile apps are the future of app development” (Nick Heath in CIO Insight, February 2013) 
“Mobile apps will soon be dead.” (Brian Kennish, former Google engineer, May 2011)
“Native Apps are dead, long live Native apps!” 
(Dan Yoder, CTO at Border Stylo in Slashdot, June 2011)
“All the problems [of mobile web] can be solved if Apple, Google, Microsoft and the rest will just stop shutting out HTML5″ (Dan Rowinski at Mozilla, November 2012)
“HTML 5 is the way almost all applications will be built, including for phones.” 
(Eric Schmidt, February 2011)

examples among big brands and media


    Facebook rebuilt their apps from scratch as native apps.

      Linkedin had a HTML5 hybrid approach and recently went native for its mobile apps.

        Twitter had fully native apps from the start.

          Instagram is a native app that wouldn't work otherwise.

            ESPN builds all their apps with native because they consider it a requirement for great sport apps.

            native apps


            Are specific to a given mobile platform using the development tools and language that the respective platform supports.

            iOS
                         		Xcode and Objective-C
            Android
            		  Eclipse/Android Studio and Java for Android
            Windows Phone
            		 Visual Studio .NET and C#

            NATIVE apps


            benefit


            Best Performance
            Work in Offline mode
            Access to the latest APIs, Releases on that Platform
            IDEs, Debugging Tools, Emulators
            App Stores

            NATIVE apps


            Disadvantages


            Slow, Hard to Develop
            Hard to Publish
            Creates Friction

            web/html5 apps

            Use standard web technologies—typically HTML5, JavaScript and CSS . This write-once-run-anywhere approach to mobile development creates cross-platform mobile applications that work on multiple devices (mostly run on browsers ).

             RWD

            web apps


            benefit

            For all platforms simultaneously 
            Speed of Development
            Very Good UI Frameworks, Tools and Libraries
            Same Appearance on all Platforms
            Only need 1 team, who can also do desktop site
            10's of millions of web developers, easy to hire
            Perfect for rapid prototyping
            Easy Distribution (web server)
            Frictionless

            web apps


            disadvantages


            Performance
            Native "uncanny valley"
            Mobile browser limitations/differences
            Limited Access to Native APIs
            No App Stores

            Side by Side, iOS vs HTML5


            iOS
              1. Sign up for a developer account (fees)
              2. Buy a Mac
              3. Set up XCode
              4. Configure project/team settings
              5. Request development certificate
              6. Register Devices
              7. Develop, Test, Debug
              8. Request production certificate
              9. Upload to iTunes, submit for approval
              10. Wait...

                SIDE BY SIDE, IOS VS HTML5


                Web (HTML5)

                1. Develop, Test, Debug
                2. Push to host


                :)

                hybrid apps

                Make it possible to embed Web Apps inside a thin native container (WebView, UIWebView...), combining the best (and worst) elements of Native and Web apps.
                Apps are packaged natively,  so has access to native APIs.

                hybrid apps


                benefit


                Faster, Cheaper to Develop 
                Small amount of native coding
                Near to ‘Write Once, Run Anywhere’
                Deployment on App Stores
                Access the Native Layers
                Can work in Offline mode
                Access to 3rd Party Code

                hybrid apps


                disadvantages


                Decreases performance
                Hard to Publish
                Creates Friction

                app development - summary


                so which one to choose?


                Rule of thumb:

                Games or Photos, Videos related Apps 
                > Native Apps

                 Work in real time, which doesn't need access to 
                the native layer and is not performance stressed 
                > Web Apps

                Productivity Apps , Utility Apps or Enterprise Apps 
                > Hybrid Apps

                html5 vs. native apps




                first round



                Reasons:

                HTML5 failed as a way to develop high-quality consumer Apps
                People really, really want the web to win
                shows the first real glimmers of hope


                .The ultimate javascript development platform.

                Project description



                "Famo.us is a powerful JavaScript framework designed to build rich, interactive web applications. It is the only framework that provides an open source 3D layout engine fully integrated with a 3D physics-based animation engine that can render to DOM, Canvas, or WebGL. Famo.us is currently in public beta."

                demo 1 - periodic table



                Open challenge to rebuild that in iOS.
                There have been no takers yet.
