“More than 4 billion people around the world now use cell phones, and for 450 million of those people, the Web is a fully mobile experience,” according to the McKinsey Global Institute. This explosive growth of mobile is having a significant impact on B2C and B2B businesses.

Mobile-enablement, however, is more than just tailoring your website’s content to fit a smaller screen. There are several options and challenges involved in going the mobile route. Executives overseeing mobile initiatives need to be aware of the considerations – in order to get the maximum RoI from their mobile strategy.

Come listen to two experienced practitioners discuss key elements that will be crucial in your mobile strategy, on June 2nd, 2011 at 2 PM EST.

HP Acquires Palm

2 Comments


HP has acquired Palm. I am happy that this happened. When ever our team had a discussion, one thing that would be part of our discussion was Palm Web OS and its UI features.We felt eventhough the UI was not unique ,it can add to their strength to rise against other bigwigs.  And when the SDK was released and when we learned that it encourages and embraces every web developer, we felt this is going to rock the entire Smart phone market. And personally I went on to  think of how their Application Store(App Catalog) is going to get crowded. But Business does not stop with just innovation,but needs the right Marketing. And due to the carrier’s choice and poor hardware quality ,(palm Pre was pitted against iPhone by many critics) their innovation that happened with the help of  some of the Apple’s former employees went in vain and finally their shares plunged and had to be acquired by HP .

Future of the Merger

So generally speaking the merger seems to benefit the both HP(giving them an readymade OS) and Palm(a seemingly stable partner, on which it can piggyback), but a merger does not stop with the the brands getting merged rather  the acquirer has to embrace, support the other at all levels. The culture of the HP if  forced on Palm’s executives or Employees, the merger would go in vain for both of them. Hope things go well and we get a good, energized competitor in smart phone market.

Palm WebOS – Web Service and Persistent Storage

Leave a comment


Hi Friends,

This article will take you through the ways of handling Web Service and Persistent Storage in Palm Web OS.

First let us look at Web Service.

Web Service

1. We can access webservice using two means.
a. Prototype Javascript Framework (Ajax.Request)
b. Native javascript (XMLHTTPRequest)
2. Exchange data can be of any form (JSON, XML, or any of your own format)
3. Currently only asynchronous operations are supported using XMLHTTPRequest, done to preserve UI responsiveness. (I have not checked with the Ajax.Request. If someone has verified it, please share them)
4.Use Prototype Javascript Framework if you don’t wish to control every operation yourself and the framework will take care of everything.
5. use Native Javascript if you wanted more control over your code.

Processing JSON:

1. Two ways:
a. eval()- best to avoid, only if source is trusted.
b. JSON parser- faster, never allow malicious script to get executed.

Processing XML:

1. use either DOM or a SAX parser.

Now lets turn towards, Persistent Storage:

Memory is partitioned as three segments:

1. root- for the OS and apps that come by default like calendar, Browser.
2. var -meant for third party Applications, that we are wiling to develop.
3. Media-media partition are visible on the USB volume( Available in your computer, when you plug-in your Palm based phone- pre or pixi).

Three ways to store data:

1. Cookie
2. Depot
3. HTML5

All three forms of data are tied to an application. So, they will be deleted, if you delete your application from the device.

Cookie:

1. Data stored as a key-value pair.
2. It has nothing to do with the Web browser cookie, other than storing data.
3. Maximum of 4KB of data.
4. Can be used to store preferences, simple settings.

Depot:

1. Can store up to 1 MB of data.
2. Size can be extended by using a keyword ext,while creating database.
3. Data stored as Key-value pair.
4. Normal way of creating DB:
var db = new Mojo.Depot({name:”demo”}, onSuccess, onFailure);
5. For extended storage:
var db = new Mojo.Depot({name:”ext:demo”}, onSuccess, onFailure);

HTML 5 database

1. It is a structured database, unlike the first two.
2. Normal way of creating the DB:
this. db = openDatabase(“myDB”, 1, “My DB”, 10000);
3. To store data in Media partition, use
this. db = openDatabase(“ext:myDB”, 1, “My DB”, 10000);

Depot and HTML5 DB operations are asynchronous, unlike the Cookies.

And thats all for this article. Thank you.
