Offline Mobile Web Applications in HTML5
An O'Reilly Breakdown
Publisher: O'Reilly Media
Final Release Date: January 2011
Run time: 2 hours 40 minutes

Although HTML5 has a ton of bells and whistles, it's very much an integral part of the coming Web, and not everything about it is flashy and sexy. HTML5 actually offers a lot in terms of enhancing your web forms. Further, you can now build applications that function when your users aren't connected to a network. This Breakdown teaches you how to build 21st century forms: they'll validate your data, respond to data type mistakes, and even keep working when the WiFi goes down.

Although browsers offer different support for HTML5 validation, your work on your forms today will future-proof then for tomorrow. What isn't for the future, though, is the support for offline apps in HTML5. You'll learn how to write to a localized data store when there's not a networked server with which to connect. Not only that, you'll learn how to sync that data back up with the network when your users reconnect to the Web.

The experts in the O'Reilly Breakdown live video series not only break down the concepts of difficult and complex subjects, they also demonstrate practical implementation and use. Each episode features an experienced programmer, developer, or software designer working on real-world challenges, ranging from iPad user interface design and multi-tasking on Android phones to caching in cloud-based applications.

    PRAISE
    - the material is covered in a step-by-step manner which makes it easy to digest.
    - the interview style kept my attention and offers a nice exchange of ideas.
    - a lot of good questions come up that help explore the topic.
    - love having a video i can review if i missed a concept or remark.

    CRITICISM
    - the code used in the videos is not available for download and not all of the code is visible within the videos.
    - left channel volume is too low when listening through a headset.
    - some questions and remarks feel too dumbed down and most of the questions seem unplanned and asked "on-the-fly" rather than planned.
    - i would have liked it if the interviewer had had a chance to review and implement the material before the recording so that he could have drawn-up a series of questions balancing planned questions with those that came up during the actual recording.
    - the interviewer missed a few chances to challenge some assumptions, such as :
    - why use html5 form attributes that are clearly implemented in inconsistent ways?
    - if i am going to use them, how do i override an implementation i don't like, e.g., date picker?
    - the material also misses one key question that was promised to be answered :
    - how do i deal with a network connection that does not have access to the internet, but does have access to a local intranet?

    OVERALL
    while i do like the format, enjoyed the series and learned from the material, i find the series overpriced and would love to see a much lower price point if all involved are able to be properly compensated.

      If you're a web developer who's holding off on HTML5, it's time to take the plunge. Luckily there are plenty of books, videos, online tutorials, and other resources to help you get started. Add Offline Mobile Web Applications in HTML5 to your list.

      In this video, developer David Griffiths walks you through an important part of HTML5 that often gets overlooked in much of the hoopla and Adobe versus Apple battles: The "blue collar part" consisting of form enhancements (without Javascript) and client-side application technology. Anyone who does database-driven web application development should get excited as Griffiths explains the process of making an offline-ready application using only web technologies. Even if you're not planning on developing for the mobile web, you'll glean plenty of good techniques on form building, offline caching, and remote caching that will come in handy in your future web application development.

      Will this video make you an expert in HTML5? No, but it will get you well on your way, and in a relatively short amount of time. Offline Mobile Web Applications in HTML5 is a solid introduction to a core technology you'll be using every day in the coming years—and now's a great time to get started.

        Comments about O'Reilly Media Offline Mobile Web Applications in HTML5:

        In this great video by OReilly, Brett McLaughlin and David Griffiths walk us through in developing offline applications using HTML5. The entire video is divided into 5 parts :

        * Blue collar HTML5
        * Creating HTML5 forms
        * Moving an App to the Browser's Cache
        * Caching Data with Local Storage
        * Syncing Local Storage to a Server

        The first part is an intro to HTML5. In the second part David illustrates the new attributes introduced in HTML5, the browser display differences and the pain points in adopting HTML5 currently. In part 3, he illustrates setting the cache.manifest file and other edit required. In part 4, he illustrates with code how the LocalStorage works, its syntax and browser support. In final part 5, he shows us how to sync up the offline cache with server copy. Also Brett and David discuss on when to adopt such offline application style, the UI and UX aspects to be taken care.

        There are numerous technologies (JSON,Ajax,Javascript...) involved in this video but David sticks to the most relevant concepts and technologies. He clearly states the pain points in adopting the approach or technology.There are numerous Tips scattered across the video and a sub-title like text appears for key points in discussion. The Dev 2 Dev kind of interaction makes the whole video very impressive.
