GoogleMap - Latitude and Longitude

I have to display the map with respect to the place given.

In that tags the longitude and latitude of the location to be passed as parameters to get the exact location in Map.

I got many examples for displaying the Google map in different way & special effects. But not able to find how get the longitude and latitude of a location/place. At last found the way. Might help someone who searches like me.

Code: To get the Longitude & Latitude of the location

To have Google map in an application. We have to get a key from this link
http://code.google.com/apis/maps/signup.html

import java.io.BufferedReader;
import java.io.IOException;

Bitly using Mashape

Mashape is an API marketplace where service providers and individual developers can instantly make available an API.Its FREE to use.

Mashape can used in 2 ways

1. Making use of the featured API’s available in Mashape
2. To generate our own API using Mashape.We can upload our API in Mashape & push it into cloud.They are providing the infrastructure for generating the API.

I tried out the first way, which I need currently to work on
Check the featured services provided by Mashape -Explore.
They are in ready to use state.Avaiable in Ruby, Java, Python, PHP Obj-C, and JSON

I tried out with SimpleGeo and Bitly.

Steps to work on Bitly using Mashape :

Step1: SignIn Mashape.Get the API key.It's an automatically generated key which allows you to use the Mashape API from an application. [Ex:API key will be like this APP Key : sgFFDCfgEOKsLMsO9X7l75gCI]


Step2: Download the featured Bitly API from Mashape .
The Jar will contain Bitly component's Java client library will contain the following files:

- mashapeClient.jar - This file to be include in the project, that contains the core
functionalities of every Java client library and that is
immutable for every component.
- Bitly.java - The auto-generated *.java file for the component, that
declares a Bitly class.
- LICENSE - README

Step3 Download the following jars to work on all the above API's using Mashape.

- httpclient-4.0.jar
- httpcore-4.0-beta3.jar
- json-rpc-1.0.jar
- json-20080701.jar

Step4 Signup in Bitly & get the bitly-login and bitly-Api-key.

Step5 Code:

//Enter Mashape API key 
Bitly bitly=new Bitly("sgFFDCfgEOKsLMsO9X7l75gCI ");

//Pass the url to be shortened, bitly-login and bitly-Api-key &it returens the JSONObject

JSONObject bitlyResponse = bitly.getShortenedUrl("http://sundarishree.blogspot.com/","shree","R_08de4b3475dd5655818230c15c4966471");

Advantage of this Mashape is no need to download the API jar from different sites. We can get in one point.

Session in PHP

This post might help the newbie to work on session in php.

1. Start up the session

session_start()
Function must appear before the html tag.Its initialize session data
Example :

   

    .

    .

   

2. Store a session variable
Example:

       session_start();

    $_SESSION['username']="Misty"; // store session data

   ?>

   

      echo "Name =". $_SESSION['username']; //retrieve session data

   ?>

   

   

Where ever we try to access[Store or Retirve] the session variable the
session_start() function has to be called once before accessing the
session variable.

3. To delete the session data

The unset() function is used to free the specified session variable:
Example:

       unset($_SESSION['username']);

   ?>

4. To destroy the session
We can completely destroy the session by calling the session_destroy()
function
Example:

       session_destroy();

   ?>  

   

session_destroy() will reset the session and We will lose all the stored session
data.

5. To check whether the session variable is null
Example:

   is_null($_SESSION['username'])==true

   

6. Some of the Session Functions
session_cache_expire — Return current cache expire
session_cache_limiter — Get and/or set the current cache limiter
session_commit — Alias of session_write_close
session_decode — Decodes session data from a string

session_encode — Encodes the current session data as a string
session_get_cookie_params — Get the session cookie parameters
session_id — Get and/or set the current session id
session_is_registered — Find out whether a global variable is
registered in a session
session_module_name — Get and/or set the current session module
session_name — Get and/or set the current session name
session_regenerate_id — Update the current session id with a newly
generated one
session_register — Register one or more global variables with
the current session
session_save_path — Get and/or set the current session save path
session_set_cookie_params — Set the session cookie parameters
session_set_save_handler — Sets user-level session storage functions
session_unregister — Unregister a global variable from the
current session
session_write_close — Write session data and end session
7. To check the page expiry using session
Example:

      session_start();

   ini_set('display_errors', true);

   ini_set('display_startup_errors', true);

   error_reporting (E_ALL);

   session_cache_expire( 20 );

   $inactive =250;

   if(isset($_SESSION['start']) ) {

    $session_life = time() - $_SESSION['start'];

    if($session_life > $inactive){header("Location:login.php?errorMsg=Your session   

     has expired.Please login again.");

    }

   }

   $_SESSION['start'] = time();

   ?>

   

This code has to placed in the pages in which we need to check for session
expiry [Session expires beyond 4 mins].


8. ERRORS -> While working on sessions in PHP you might
come across the following errors. I got these 2 errors.

8.1 Warning: session_start() [function. session-start]: Node no
longer exists in C:\wamp\home.php on line 3
occurs if a object is taken from a xml file or format.

Cannot serialize object wrapping 3rd party library structs. Must serialize
the xml (to a string) and store that to session and reload the xml when
restoring from session
Example

       session_start();

       /*To get  from the mail.xml  */

       $xml = simplexml_load_file("../mail.xml");

        foreach($xml->children() as $child){

           if($child->getName()=='servername'){

               $servername=$child;

           }else if($child->getName()=='dbname'){

               $dbname=$child;

           }else if ($child->getName()=='username'){

               $username=$child;

           }else if ($child->getName()=='password'){

               $password=$child;

           }else if ($child->getName()=='url'){

               $url=$child;   

           }

        }

      $_SESSION['url']=(string)$Url; // Casting is required

      

8.2. The following error might occur when we try to re-direct the page from one
page to another.

Warning: Cannot modify header information – headers already
sent by (output
started /home/kvel/kyybaventures.com/laton_v/views/leftnav.php:28) in
/home/kvel/kyybaventures.com/laton_v/views/welcome.php on line 10


The problem is mainly due to the header start writing the output and again
trying to resent the header information. Normally when we use echo statement
before the header, this type of problem will come. It will not reflect in
the development environment and if try to deploy the code in the remote
server, this problem used to occur. Even if you remove the echo statement
and still the problem persist, follow the below solution.

To get rid of this error use these two lines

at the start of the php file and

at the bottom of the php file where you got the above error.

Searching for PAAS providers

In near future I think everything in the IT going to be virtual. Its going to play a main role in transforming IT infrastructure toward cloud computing.

In 2011 many more enterprises virtualized and get onto private cloud journey as next step.
Surely will be great competitions between the Cloud Service providers.

We too trying to get into cloud service .As a first step our team is searching for PAAS providers which suits to develop our social media based application. We are trying for a provider which supports java.

Did some analysis on Bungee connect, Joyent & WSO2.

Regarding,
Bungee Connect – They have given as they collects no fees during the entire development process developers can freely access, develop, test, and even conduct on-line focus groups and beta programs for Bungee-powered applications.
After surfing a day, we felt this is best for us. Tried to work with beta .They have not yet released their beta work.
Might be in near future they might release the beta but we can’t wait for it.

Joyent -Fully java script based application can be build. Mainly games are developed using joyent.Having big clients. We can use any sort of editors.Price differs based on the platform .Starting from 1/4GB Standard platform $25 /month to 32GB- $4000/ month. Not having clear view for making the development environment.
Also don’t know whether it suits to build our application.

WSO2 –Specified they offer a complete lean enterprise middleware platform, available as open source.Provided all sorts of download for services like mashups,data service,gadges etc.,.Provided many video files ,tutorials to work WSO2 services.

When we go through the video, tutorial & definifiton it seems like “Spoon
Feeding”.But when tried practically something is missing. Some notch in the flow of integration.
There comes the check they have kept all sort of pricing in the name of support.Showing the great business.

We are trying this as a first application in cloud so we are not ready to afford much on this trial.

Still searching is not completed.

About CLOUD COMPUTING from a Tenderfoot

I can't say its an IN and OUT about CLOUD COMPUTING.This post might give a light idea for you before start flying into CLOUD.

Cloud computing is making a new trend and revolution for the next generation IT engineers.So many views and definitions are there on internet.This one gives a simple understanding definition for cloud computing

"A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption"

Already We are using some kind of cloud ser­vice, such as Web email (Gmail, Yahoo! Mail or Hot­mail),online data stor­age (IDrive, Mozy) or online soft­ware.

Cloud Environment is divided in three segment
SAAS
PAAS
IAAS

SAAS - Software As A Service

Provides software applications to end users without requiring the end user to run the application on their own computer.
Increasingly popular with Small and medium enterprises(SMEs).
No hardware or software to manage .
Service delivered through browser.

Examples of SAAS

CRM
ERP
Project Management
Banking
Spreadsheet

PAAS - Platform As A Service
Is an environment for running custom applications that provides operating-system level services for accessing the hosting and hardware resources needed in a cloud.
Some PaaS have their own dedicated SaaS architecture (For example : Salesforce's Force.com).
Most platforms anyway allow the consumer to choose their own SaaS tools.

Example of PAAS

Google App Engine
Mosso (Hosting cloud service)
AWS: S3(A Ruby Library for Amazon's Simple Storage Service's (S3) REST API)

IAAS - Infrastructure as a service
Is a form of hosting.
It includes network access, routing services and storage.
The IaaS providers will usualy provides the hardware and administrative services needed to store applications and a platform for running applications.


The cloud has become

1.our enter­tain­ment net­work we are spend­ing hun­dreds of mil­lions of hours on sites like YouTube , Flickr and so on.

2.our social net­work Face­book,Bebo, hi5 ,MySpace and sim­i­lar sites now claim hun­dreds of mil­lions of mem­bers.

3.our work­bench we man­age projects in Base­camp, share large files with Pando,tweak pho­tos in online photo edi­tors like Adobe Pho­to­shop Express and Pic­nik.

4.our devel­op­ment net­work open source pro­gram­mers trade code on sites like SourceForge.net and Drupal.org.

Still not started to fly in CLOUD.While I do,surely i will post the next.
