Signature Spider at National Park.

I found this spider at Borivali National Park. When I clicked the pic I never knew that this is the signature spider, on of my friend told me about this so I googled it and here is the information. For me it's a WEB DEVELOPER who don't forget to mention copyrights on his web-site. :) These spiders make certain zig-zag pattern on web therefore also known as writer or signature spider.This spider weaves four zig zag stripes in its web, and holds its legs together in pairs. It holds its legs in pairs to disguise itself as a four legged creature; it does this to not appear to look like a spider. These spiders have many names around the world, they are known as an Argiope, a Black and Yellow Garden Spider or a Writing Spider in North America. It is known as Wasp Spider in Germany and the rest of Europe and the St Andrews Cross spider in Austrailia. They know it as KOGANE-GUMO in Japan and east asia. There are 75 different species of this spider but they all look the same. Their colours vary in between their stripes but they all keep the black and yellow stripes, They distribute also Sri Lanka, Maldives,India, Pakistan.Their habitats are Moist Deciduous forests in the sunny parts.

Alternative of google-map API, making request more than 2500.

I was looking for a free api which can help me to get latitude/longitude on the basis of Postcode.

I tested pygeocoder and other api librearies which can help me, but none of them allowed me to query more than 25,000/day cause everyone is belongs to Google.

So I did an old school coding by using Mechanize and BeautifulSoup.
I used http://services.gisgraphy.com/public/geocoding.html. It's a free, I think they are providing 30,000 requests for demo user, I didn't tested 30,000 requests cause I've 29,000 records to generate lat/long. I don't want to waste my hits for a day. I'll test and update here.

Code is not clean, cause it's a test.

Keep Coding .


import mechanize
from bs4 import BeautifulSoup 

for x in xrange(30000):

    print '----------------- searching ---------------'
    br = mechanize.Browser()
    br.open("http://services.gisgraphy.com/public/geocoding.html")
    
    add = '81100'
    con='Malaysia'
    
    br.select_form(nr=0)
    
    br.form["address"] = add
    for i in range(0, len(br.find_control(type="checkbox").items)):
        br.find_control(type="checkbox").items[i].selected =True
    br.form["country"]=["MY"]
    
    print 'hitting --- ',x
    response = br.submit()
    soup = BeautifulSoup(response)
    
    
    links = soup.find_all('li')
    print '--------- getting list ----------'
    
    li = soup.find('div', {'class': 'summary'})
    
    print '---------- looking for latitude and longitude -------------'
    list= []
    children = li.findChildren()
    for child in children:
        list.append(str(child))

    print ' found latitude and longitude at point -->  ',x
    
    latitude = list[0]
    longitude = list[1]
    
    lat = latitude[9+5:len(latitude)-5].split()
    lng = longitude[9+6:len(longitude)-5].split()
    
    print str(lat).replace(',','.')
    print str(lng).replace(',','.')

#for f in br.forms():
#    print f

Changing wallpapers in Crunchbang #! Linux .

I'm using crunchbang #! when it was #!-9 around in 2010 , now using #!-11. Between these period I tested out many linux distros but never feel that any linux is stable as #! is now, because it drops Ubuntu and using Debian-stable :) .
As per the heading of this post to change wallpaper in Crunchbang we need to copy paste the wallpapers( images ) into following directory./home/[username]/images/wallpapers/shared/
But "shared" folder is locked, so we need to copy-paste the images as a "sudo" user. Please Follow the steps.
1 Press "alt+f2" then enter "sudo thunar" and enter your password.
2 Now copy your wallpaper(images) and paste it into "/home/[username]/images/wallpapers/shared/" directory.
3 "Right-click" on the desktop and navigate to " settings > Choose Wallpaper ".
4 Now you can easily see the images and set the wallpaper by selecting images and clicking on "apply" button.

Here is my wallpaper link

Wait for the next crunchbang post. Keep Coding :)

Network Manager not running on Ubuntu12.04 at boot-time

I was configuring PPPOE connection manually by command line using "sudo pppoeconf", and by mistake I changed some settings. So after I restarted my laptop, I was getting an boot time error "waiting for network configuration" and after some time "waiting upto 60 seconds more for network configuration.."
Also there are possibilities to get this error while upgrading the system.
I solved these problem by using 2 methods.
After logged into Ubuntu.
Open terminal, type
First : not a permanent solution
  sudo /etc/init.d/network-manager start
Second : permanent solution
  sudo gedit /etc/network/interfaces
And remove the lines after
  auto eth0
  iface eth0 inet loopback
Make sure to save the file before closing it.Reboot the system

Sending Email : Django Terminal Test.


While I was making contact-us form in PHP for my client then I thought about to do same in Djago-Python. Target was to get the form input and email it. Here I'm going to test only the DjangoEmail module using shell.
Edit settings.py with code below:
    #settings for django email( writing for gmail)
    EMAIL_USE_TLS = True
    EMAIL_HOST = 'smtp.gmail.com'
    SITE_HOST = '127.0.0.1:8000'
    DEFAULT_FROM_EMAIL ='Dotorbit Team '
    EMAIL_PORT = 587
    EMAIL_HOST_USER = 'dotorbit.dev@gmail.com'
    EMAIL_HOST_PASSWORD = 'your-password'
    #Run interactive mode, 
    python manage.py shell
    #Import the EmailMessage module,
    >>>from django.core.mail import EmailMessage
    #Send the email,
    >>>email = EmailMessage('Subject goes here ', ' Body goes here ', to=['reciever@email.com'])
    >>>email.send()
    >>>1

This will return 1, means everything is working fine. form and view, I'll write in next post.

Configure LAMP and How to fixing Apache issue ServerName issue.


There are lots of tutorials available for Apache,MySql and PHP installation on linux and Windows. But I prefer the simple one for Debian.Command will not work without caret(^). sudo apt-get install lamp-server^ Now,This will download and install the Apache,PHP and MySql. step1 : test "localhost" in browser. Works !!
step2 : run the apache2 service. $ sudo service apache2 restart
or
$ sudo /etc/init.d/apache2 restart
If it works !! You are champ.
For me ,It throws an error --
codeleaf@dotorbit-backbox:/media/Development/Developer/HEROKU/DotOrbit$ sudo service apache2 restart
* Restarting web server apache2
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
I googled about it and found the solution,
By default "httpd.conf" file will be blank. Now, simply add the following line to the file. $ sudo gedit /etc/apache2/httpd.conf Add the following line to "httpd.conf" and save it . ServerName localhost Now restart the server. $ sudo service apache2 restart
$ * Restarting web apache 2 server
... waiting
Woohoo.. It works
step3 - Test whether PHP is working or not ? Create "test.php" in /var/www/ directory. $ sudo gedit /var/www/test.php and add following line " < ?php phpinfo(); ? > step 4 - Test localhost/test.php and you will get the info page. e.g "PHP Version 5.3.10-1ubuntu3.4"

How to install 686-PAE kernel on Linux Mint Debian Edition-i486?


Before using Linux Mint Debiab Edition(LMDE) I was using Ubuntu-12.04LTS .
It was my worst experience with ubuntu. It looks like Ubuntu12.04LTS is not matured. I've faced lots of problems like touchpad freezes , after updates system get crashed , lots of bug reporting etc . Anyway I'm not anti-ubuntu .
In frustration I removed Ubuntu12.04 and installed LMDE on my Dell Vostro-1540 (core-i3).
Since the kernel is built with LMDE 201 109 486, then the default kernel is only able to detect a single core . Result was ,I've experienced some sort have 'hang' during my Android application development .
I decided to install the kernel 686, exactly 686-PAE. This kernel is the best solution for running LMDE on 'multi-core' system .
No need to worry about it .
Simple steps are here to install linux-kernel-i686.
 $ sudo apt-get update
 $ sudo apt-get install linux-image-686 linux-headers-686-pae
for i486.
 $ sudo apt-get update
 $ sudo apt-get install linux-image-486 linux-headers-486
for amd64.
 $ sudo apt-get update
 $ sudo apt-get install linux-image-amd64 linux-headers-amd64

send tweets from pythom , using python-twitter ...simple way ( 5 steps )

Today morning around 4am , when I was designing my codeleaf blog site I just thought of tweeting something interesting but I dont wanted to tweet from the twitter Page. Instead, I wanted to tweet from terminal where I was doing other programming stuffs... So I decided to write a python-script to Post a tweet from my Terminal .
So I googled about "tweet from python" and I came across python-twitter and I started following Wiki for implementing that thing .
Steps that need to be followed are as follows ::
1. Register an Application on Twitter Dev-Center
Set your application's "Access level : Read, write, and direct messages "
Otherwise you will get an error for "Access level : Read Only"(TwitterError: Read-only application cannot POST.)

2. Copy your
 consumer_key = 'consumer_key',
 consumer_secret = 'consumer_secret',
 access_token_key = 'access_token_key',
 access_token_secret = 'access_token_secret'
and paste on some TextEditor ,because we will use this later .
3. Installation ( Python-Twitter )

Install the dependencies:
If your python-version > python2.7.2 , then skip first two library and directly install the third-one(python-oauth2) .
Download the latest python-twitter library from:
Extract the source distribution and run:
 $ python setup.py build
   $ python setup.py install
 

4 . create a python file and write the below code on it .

  
 import twitter
 api  = twitter.Api()

 #tweet
 def tweet(tweet_status):
  status = api.PostUpdate(tweet_status)
  print "Posted successfully"
  print status.text

 # OAuth authentication
 api = twitter.Api(
  consumer_key = 'consumer_key',
  consumer_secret = 'consumer_secret',
  access_token_key = 'access_token_key',
  access_token_secret = 'access_token_secret'
 )

 tweet_status = raw_input("Tweet Status : ")
 tweet(tweet_status)

5. Thats it . Now run the script , and Terminal(command prompt) will ask you to enter your "Tweet" .

 $ python pytweet.py 
   Tweet Status : I love Python-Twitter .
   Posted successfully
 Tweet Status : I love Python-Twitter .

Deploying Django app on Heroku platform

Before using Heroku , I used Django-nonrel with Appengine , Django-Appengine , Google Appenigne , FluxFlex , Gondor hosting and Alwaysdata . From my knowledge I think Django-app deployment on Heroku is easier than others . When I was following official tutorial of django app deployment on Heroku , I got some errors so I googled and fixed all those errors . This is Heroku's official Documentation .Deploy Djang on heroku . Lets Start 
Install Heroku-toolbelt
wget -qO- https://toolbelt.heroku.com/install.sh | sh
1.Create folder called Heroku and move into it . $ mkdir Heroku && cd Heroku
2. Create a virtualenv and Activate your virtual environment
$ virtualenv --no-site-packages venv $ source venv/bin/activate This will change your prompt to include the project name. (You must source the virtualenv environment for each terminal session where you wish to run your app.)
3. Install dependencies with pip: $ pip install Django psycopg2 This step was failed for me , During Installation of "pip install psycopg" I got "Error: pg_config executable not found."
Linux User(debian based) : Make sure that u have "libpq-dev python-dev " packages installed . I used following command to install the above libraries $ sudo apt-get install libpq-dev python-dev for Windows User click here :
4.Great job ! Now Its time to create a Django app in the current directory: $ django-admin.py startproject greetingheroku .
5. Test the app runs locally by starting up the Django development webserver: $ python manage.py runserver
6. Create a pip requirements file which declares our required Python modules: $ pip freeze > requirements.txt All packages required should be declared explicitly in requirements.txt:
  $ nano requirements.txt
    Django==1.4
    psycopg2==2.4.5
now type ctrl+o(save) and ctrl+x(exit)
7. Commit to Git create .gitignore file and Exclude Virtualenv , because we don't want to push our local envirnment to heroku :
  $ nano .gitignore
    venv
    *.pyc
use ctrl+o(save) & ctrl+x(exit) . You will use Git to deploy code to Heroku
8. Initialize a Git repo and commit the project (if you aren’t already tracking your project with Git):
  $ git init
    Initialized empty Git repository in /home/ashish/developer/Heroku/greetingheroku/.git/
  $ git add .
  $ git commit -m "my django app" 
  $ heroku keys:add

9. Deploy to Heroku Create an app on the Cedar stack:
  $ heroku create --stack cedar
    Creating simple-spring-9999... done, stack is cedar
    http://simple-spring-9999.herokuapp.com/ | git@heroku.com:simple-spring-9999.git
    Git remote heroku added

10. Deploy your app: $ git push heroku master If "git push heroku master" gives you an error something like "heroku does not appear to be a git repository ." Then run the following command to add heroku as a git repository . Mostly this will happen , when u changed your app name from "Heroku dev center " $ git remote add heroku git@heroku.com:your-app-name.git
11. Check to see that your web process is up, to start $ heroku ps View your logs: $ heroku logs
12. finally visit your app on the web. $ heroku open
13. Syncing Database $ heroku run python manage.py syncdb 14. Using Django Shell $ heroku run python manage.py shell

How To Reset Unity in Ubuntu-11.10 .

Today I installed Ubuntu-11.10 and I was playing around with Ubuntu, trying different themes, different engines, different window managers,file-managers(dolphin-one of my favorite), etc.
After installing CompizFusion, I started playing with themes and bymistakly, I removed my unity-panel.
So there was no shortcut to run app with "Alt+f2" key.
Thank god,I had installed Awn-dock , then I started firefox and googled about it and finally I did reset my unity2d settings to default.

Reset Unity
If you want to reset Unity (this will only reset the Unity settings in CompizConfig Settings Manager and leave the other CCSM settings intact), open a terminal (or press ALT + F2) and enter:
$ unity --reset
Reset Unity Launcher icons
$ unity --reset-icons
Here are some useful links which is more about " Customization "
Install Docky
Docky will be added under Accessories in the Applications menu.
$ sudo add-apt-repository ppa:docky-core/ppa
$ sudo apt-get update
$ sudo apt-get install docky

*If i will find some more interesting links,i will post here .

Django-nonrel with mongoDB

Hi friends , I'm working with Borgets Solution. Recently I made a simple application on Django-nonrel with backend mongoDB.
Django-nonrel is an independent branch of Django that adds NoSQL database support to the ORM.Read more about the django-nonrel Django-Nonrel ...
I feel its somewhere bit complex to configure mongodb as backend on "Django-Nonrel" and make "Django-Administration" working.
lets start.

Installation


If you like to use Virtual-environment , then you can use it . Install pymongo
You need setuptools for installing pymongo , dont worry dunring installation of Pymongo , autamatically setuptools should be downloaded .
  • Download pymongo
    extract pymongo.tar.gz folder and install .
    	ashish@developer:~/Downloads $  tar -xzvf pymongo.tar.gz
    	ashish@developer:~/Downloads $  cd pymongo 
    	ashish@developer:~/Downloads/pymongo $ sudo python setup.py install 
    
  • or you can use $ easy_install pymongo

Install djangotoolbox
  • Download SourceCode of djangotoolbox and extract it > DjangoToolBox
    extract django-toolbox zip file and install .
    	ashsih@developer:~/Downloads$ unzip wkornewald-djangotoolbox-.zip
    	ashsih@developer:~/Downloads$ cd wkornewald-djangotoolbox-
    	ashsih@developer:~/Downloads/wkornewald-djangotoolbox- $ sudo python setup.py install
    

Install Django-nonrel
  • Download SourceCode of Django-Nonrel and extract it > Django-Nonrel
    	ashsih@developer:~/Downloads $ unzip wkornewald-django-nonrel-.zip 
    	ashsih@developer:~/Downloads $ cd wkornewald-django-nonrel- 
    	ashsih@developer:~/Downloads/wkornewald-django-nonrel- $ sudo python setup.py install 
    
Install MongoDB
  • Download MongoDB from official site of MongoDB and extract the Tar.gz package .
    I am using 32-bit . please prefer MongoDB installation on Linux
    	ashsih@developer:~/Downloads$ tar -xzvf mongodb-linux-.tgz 
    	ashsih@developer:~/Downloads$ cd mongodb-linux- 
    
  • Create a data directory
    	$ sudo mkdir -p /data/db/
    	$ sudo chown `id -u` /data/db
    
    You can also tell MongoDB to use a different data directory, with the --dbpath option.
    Run and connect to the server make sure that you are in MongoDB package folder .
    	ashsih@developer:~/Downloads$ cd mongodb-linux-/bin/
    	ashsih@developer:~/Downloads/mongodb-linux-/bin/ $ ./mongod				
    

Install django-mongodb-engine
  • Download source code of django-mongodb-engine from here > Django-MongoDB-Engine and extract it .
    	ashish@developer:~/Downloads$ unzip django-nonrel-mongodb-engine-.zip 
    	ashish@developer:~/Downloads$ cd django-nonrel-mongodb-engine-
    	ashish@developer:~/Downloads/django-nonrel-mongodb-engine-$ sudo python setup.py install
    

Phew !!! .. finally we completed .... :)

Let's start developing Django applcation


create new django Project
	$ django-admin.py startproject djangobookmarks
	$ cd djangobookmarks/ && python manage.py runserver
Open your browser and check > "localhost:8000" address
create new django application
	$ django-admin.py startapp bookmarks

Configuration

Database setup is easy as native django with sqlite3. Open "settings.py" and setup database "mongodb_engine".

DATABASES = {
'default': {
'ENGINE': 'django_mongodb_engine', # Add 'postgresql', 'mysql', 'sqlite3' etc.
'NAME': 'newdb', # Or path to database file if using sqlite3.
'USER': '', # Not used with sqlite3.
'PASSWORD': '', # Not used with sqlite3.
'HOST': 'localhost', # Set to empty string for localhost. Not used with sqlite3.
'PORT': '27017', # Set to empty string for default. Not used with sqlite3.
}
}

Lets start mongodb engine

$mongod
$mongo

Run server
$python manage.py runserver



Yeah,Now start developing your application as other databases.Here I'm not going to teach in details.please read "django docs"

Django Admin Activation.

If you want to use Django Administration,Than it is bit tricky..
Open "settings.py" and add "django.contrib.admin" in INSTALLED_APPS.

INSTALLED_APPS = (
...default apps...
# Uncomment the next line to enable the admin:
'django.contrib.admin',
# Uncomment the next line to enable admin doc.:
# 'django.contrib.admindocs',
'bookmarks',
)

Open "urls.py" and "uncomment the lines to enable django administration"

from django.conf.urls.defaults import *

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

from bookmarks.views import *

urlpatterns = patterns('',
.....
# Uncomment the next line to enable the admin:
(r'^admin/', include(admin.site.urls)),
)

Here is my "models.py" .

from django.db import models
from django.contrib.auth.models import User

# Create your models here.
class Link(models.Model):
url=models.URLField(unique=True)
def __unicode__(self):
return self.url

Bookmark(models.Model):
title=models.TextField(max_length=100)
user=models.ForeignKey(User)
link=models.ForeignKey(Link)
def __unicode__(self):
return self.title


create "admin.py" in application directory and register the models in django admin.

#!/usr/bin/env python
from django.contrib import admin
from bookmarks.models import Link,Bookmark #Models
admin.site.register(Link)
admin.site.register(Bookmark)


It will works without "django site".

Django Site registration
For more information visit django's documentation for The "Site" framework

Open "settings.py" and set SITE_ID for django_site(django administration).

Note :
Default SITE_ID is "1".That's for SQL based databases,but NoSql based DB generates Alphanumeric object Id.so we need to set that id here.
Open terminal and write.(for mongoDB)

$mongoexport -d (database_name) -c django_site
#example
$mongoexport -d mydatabase -c django_site

now,copy "id={}" and set SITE_ID="xxxxxxxxx" in "settings.py".
SITE_ID = '4dbea69bc9ce44192b00001d'



$python manage.py mongod
$python manage.py syncdb
$python manage.py runserver



Download Django_bookmark code
Thanking You !!!

My first play-framework application : DentoX2 - A System For Dentist

Hey everyone,
Thanks to all members of Play-googlegroups and my friends Priyanka & Pavan who help me to solve my technical doubts.
Finally i finished my Academic project in Play-Framework,It was most pleasing days of developing application with play,and really the result was probably the best.
The Project is "Dental Clinic Management System" with the name DentoX2 (suggested by priyanka )

UI theme for Administrator>Pillu-Web app theme

    Another adventures and experiments with Play on my Linux !!

    Hey everyone,
    Along with my recent adventures and experiments with Play, I decided to force myself to become more proficient with Play. For all those who don't know what “Play” is , I will give u all a just of it..

    The Play framework is a clean alternative to bloated Enterprise Java stacks.

    I think its very nice framework to make web-based application by using any editor like Komodo or Emacs,and it provides libraries for database access,error handling,templating framework and session management,security,an automated test suite, a shiny web interface and an administration area and it also provides the codes for reuse.


    so, if u still feel like I need to be set straight,any suggestion or any question,Send me an email.

    Anyway,
    I have been using Linux since about 2007.
    I had JAVA self extracting file which was given to me by Mr. Jitendra Vishwakarma.
    So,I tried to run play in my Linux with the help of documentation.
    I had java ,but "i don't know how to install it?"

    Ever since I first started using Linux, I have been using Terminal for installing most of software's and applications...even today I do so.. ,
    really I don't know many commands of Linux.


    So, once again I started searching on Google about "how to install java in Linux ". I found solution for it and I dabbled with a tutorial here and there...and finally I get the java on my Path.

    My recent experiment with JAVA Installation has proved to be very fruitful, I say so to myself.

    If anyone is much interested to know "how to install the java in Linux?",then follow the instruction and commands.

    ~~~~~~~~~~~~~~~~~~~~~~~~
    Download and copy jdk-6-linux-i586.bin to $HOME/src (or a location of your choice).
    type>>
    % su -

    (some linux use "su" command and some don’t. So in such a case, use the "sudo" command and it will prompt you for a enter admin password. once u have entered the password it will not ask u again and again during the editing, deleting, moving the files .)

    "I don't know much about the RedHat and the Solaries,but as I have worked on ubuntu based linux, it accept the "sudo" command...."

    ~~~~~~~~~~~~~~~~~~~~~~~~

    #su (or sudo)
    # mkdir /usr/java (if it doesn't exist or start the line with "sudo")
    # mv $HOME/src/jdk-6-linux-i586.bin /usr/java (if it doesn' start line with "sudo")
    # cd /usr/java (if it doesn' start line with "sudo")
    # chmod +x jdk-6-linux-i586.bin (if it doesn' start line with "sudo")
    # ./jdk-6-linux-i586.bin

    ~~~~~~~~~~~~~~~~~~~~~~~~
    It will extract all the files of java and install it in your system.
    ~~~~~~~~~~~~~~~~~~~~~~~~
    Set the PATH and JAVA_HOME environment variables: (/etc/profile, $HOME/.bashrc or $HOME/.bash_profile).

    PATH=$PATH:/usr/java/jdk1.6.0/bin
    JAVA_HOME=/usr/java/jdk1.6.0
    export PATH

    ~~~~~~~~~~~~~~~~~~~~~~~~
    for more information about Java Installation try this "Enterprise Java for Linux HOWTO".

    After installing the java,I started developing the Simple Web-Application in Play.
    Here are the steps of creating application.

    Installation of play is very simple.
    Just download the latest binary package from the Play download page and unzip it to any path. Play uses command line a lot for creating,running and testing the application,it’s better to use a Linux or MacOS ,if you are using windows,its also fine.

    Play is correctly installed,now start Creating a Play application is pretty easy and fully managed by the Play command line utility.That allows for standard project layouts between all Play applications.

    Open a new command line and type:

    $python play new helloworld

    It will creates a new helloworld application.
    now we need to test it if its working or not?

    For run the application>Open a new command line and type:

    $python play run helloworld/

    Play will now load the application and start a Web server on port 9000.
    You can see the new application by opening a browser to
    http://localhost:9000


    Here is the snap of the simple " hello-world "application and "how to set the JAVA_HOME path in snap"

    And follow the Documentation for making "helloworld" application.

    PlayFramework on my linux !!

    Hey everyone,
    Along with my recent adventures with play,I decided to force my self to become more proficient with Play.For those who don't know about the play ,

    "The Play framework is a clean alternative to bloated Enterprise Java stacks. It focuses on developer productivity and targets RESTful architectures." I think its nice framework to make web-based application with the help of using any editor like Komodo or Emacs...rather than using "DotNet technology or NetBeans with JAVA" for making the Web-Based application.

    There are often religious-grade battles those who believe in .net framework and NetBeans,another surviving application development technology, editor and framework for making web-based application using JAVA environment or etc.

    I'm not trying to get into any debates about which is better and I'm not interested to know why I should not be using the .Net Technology or NetBeans for my project.
    so,if u still feel like I need to be set straight,Send me an email

    Anyway,
    I have been using Linux since about 2007.
    I had JAVA self extracting file which was gave me Jitendra Vishwakarma.
    So,I tried to run play in my Linux with the help of documentation.
    I had java ,but "i don't know how to install it?"

    Ever since I first started using Linux, I have been using Terminal for installing most of software's and applications...at this time also ,really I don't know many commands of Linux.

    So, once again I started searching on Google about "how to install java on Linux ". I found the solution for it and I dabbled with a tutorial here and there...and finally I get the java on my Path.

    My recent experimentation with JAVA Installation has proved to be very fruitful, if I do say so myself.


    If any one much interested to know "how to install the java on Linux?",then follow the instruction and commands.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    Download and copy jdk-6-linux-i586.bin to $HOME/src (or a location of your choice).

    type>>

    % su -

    (some linux are accept the "su" command and some are not,So in case of this problem use the "sudo" command.And it will prompt you for a enter admin password,once u have entered the password it will not ask u again and again during the editing,deleting,moving the files .)

    "I don't know much about the RedHat and the Solaries,but ubuntu based linux accept the "sudo" command...."

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


    #su (or sudo)
    # mkdir /usr/java (if it doesn't exist or start the line with "sudo")
    # mv $HOME/src/jdk-6-linux-i586.bin /usr/java (if it doesn' start line with "sudo")
    # cd /usr/java (if it doesn' start line with "sudo")
    # chmod +x jdk-6-linux-i586.bin (if it doesn' start line with "sudo")
    # ./jdk-6-linux-i586.bin


    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    It will extract all the files of java and install it in your system.

    Set the PATH and JAVA_HOME environment variables: (/etc/profile, $HOME/.bashrc or $HOME/.bash_profile).


    PATH=$PATH:/usr/java/jdk1.6.0/bin
    JAVA_HOME=/usr/java/jdk1.6.0
    export PATH

    After installing the java,I started developing the Simple Web-Application in Play.
    Here are the steps of creating application.

    Installation of play is very simple.
    Just download the latest binary package from the download page and unzip it to any path.Play use the command line a lot, it’s better to use a Unix-like OS.

    Play is correctly installed, it’s time to create the hello world application. Creating a Play application is pretty easy and fully managed by the Play command line utility. That allows for standard project layouts between all Play applications.

    Open a new command line and type:


    $python play new helloworld


    It will creates a new helloworld application.
    now we need to test it,either its working or not?

    For run the application>

    Open a new command line and type:

    $python play run helloworld/



    Play will now load the application and start a Web server on port 9000.
    You can see the new application by opening a browser to http://localhost:9000

    My first Encounter with PlayFramework !!!!

    Its a story very funnny and yet close to my heart...
    I just thought to share this with you.

    One month prior,everything in my life was going fine and very smooth. I was very happy with my python,my Django and was very engrossed in making different different application as a testing. I was so much happy and content with my work.. It seems that i got everything I'm my life. Don't want anything else now..

    Now as I'm in Final year of my Computer Science course i decided to make a very dynamic application which i haven't made yet,something big and challenging which will be my best work uptil now and i should reach my satisfaction level.....

    The day wen i went to college and i was still very happy with my plannings.. But the moment wen i got syllabus from my class teacher "Mr. Aishwarya Garg" and wen i just glanced on it..all my excitement was shattered....... projects have to be made either in "JAVA" or in ".NET"...

    That day was the worst day...I was very sad and totally discontent.... I wanted to pursue something big in Python...It's my passion....i just wanted to work in it only.... whole day i was thinking about python,syllabus,.Net and JAVA....My head was spinning between all of them....

    Finally at night when i came out of trauma that i was going through during the whole day... i started thinking now what should i go with.... I m not interested to learn "Dot Net" because most of my friends are going to make "Windows Application" using ".NET "...
    so i was not willing to think about it...I just ignored it.....

    The only option left was to select "JAVA"...
    "JAVA" was something that i am not interested to learn it for project, i also don't love it as the way i love "PYTHON"...but anyhow i made my mind and selected "JAVA" in utter pain....

    I decided to make a "web application in java...." but i don't know much about it excepts for the basic concepts.... but that was not a prob...."

    I told myself "MERE PASS GOOGLE HAI"...
    This word came from my Guru "PAVAN" who taught me to "how to use Google ?" and always he told me "Google Se pooch ! " . So thanks to him.
    " GOOGLE gives me all my answers.... "

    I started my rigorous searching on Google about "WEB-FRAMEWORK IN JAVA ".
    I'm searching...searching......but nothing excited me as my Python and Django
    I just love them....
    My search was going on and on and on...
    Then it was around 3am morning wen i started getting tired and sleepy....but i dont want to give up....i don't wanted to sleep....all that i wanted was to search something that excites me....

    I started getting hungry, i went in kitchen to search something so that i will not get sleep....
    I got my favorite "PARLE 20-20 (Short may niptao)"
    My mom anyhow came to know that I'm still awake and she started shouting at me...
    "kitna pareshan karta hai...din may bhi nai sota and raat may bhi jaagta rehta hai...kab soega...soja"
    but I hate wen somebody disturbs me in my work....
    I told her "Mom tum so jao...main thode der me sounga..."

    Now I sat in front of My Computer and started eating cookiee biscuit ...and again continued hunting for web framework........
    I found many "java web-frameworks".when I came across Cocoon.....But my mind said NAaaaa its not interesting.......Then "Cricket"...."hmm sounds good" but i was excited to know more about other java web-framework...
    I just opened my notebook and wrote the name "Cricket" and continued searching.....
    heehehehe.... then i came across "Spring,Struts,Tapestry " etc....
    but they were heavy ..
    it dint excited me.......
    I got irritated but still kept my search on......
    Then as i was surfing... and i wrote on Google "light-weight web-framework for java".....then I selected one hyperlink....
    Then something flashed in front my eye.....something that had a very excited name....... and I suddenly stop and read it.......

    It was "PLAY"............what...play...What is it? i started scratching my head....the moment i clicked on it,all my prob came to an end....It has got a exciting name....then even i thought to play with it....I stared reading its documentation over and over an over....
    I just cant stop reading it....plus its features and concept excited me.....It had a flavor like "Django" and "Ruby on Rails" that was the thing that increased my excitement and expectation a lot.... It was light,scalable,fast and robust and many more...more ...and more......wow...i was so happy with it...... I saw the demo video and thought that it is very easy to work with and something that i can do along with my TY studies and my python..plus it has got a beautiful look and feel and Admin facility just as my Django gives me....I quickly downloaded the software..and start testing in Windows XP.

    I started discovering it more and more and more.......It was around 5am in morning...i got tense that whether i should go to college or not...but i didn't care much about it...i started installing it following all the steps written in Documentation....

    But then i started getting error.... i was trying and getting seriously confused that I'm installing the way it should be....But man y it is not happening....y.....whats the prob yaar....
    Then it showed a error.....

    "sh:./play: /usr/bin/python: bad interpreter: no such file or directory"



    It means it requires "Python".......what python.....I got excited but was also confused.....Then i started intense investigation....Out of all my Curiosity,I came to know that PLAY Framework which is a java web framework is using python...

    Why Python ?? it was my first question..so i got the answer..
    ""
    We need a lot of scripts to manage Play applications, like creating a new application, running it, launching a browser, etc… Of course we could write these in Java directly. But running a Java VM for simple tasks like project creation is very slow. And Java itself is very limited when it comes to OS interaction.

    Python allowed us to write these scripts in a completely portable way. It’s fast to run, easy to write and available out of the box on most systems. It’s not on Windows, that’s why play comes with the bundle of a "Windows Python binary" with the framework.
    ""

    .....wow.........i was so happy that time.....somewhere I'm using python too in my project........really it made me smile and all my search was not in vain.....
    I finally selected it for my project...... I was so so so happy.......

    I told this to all my friends.....They heard this for the first time....They gave me a very bad expression and suggestion....But huh...who cares for them...I told this to my mam, she gave me a very blank look ......but I have decided to go with it, so no body can change my mind....I have not selected it for the purpose of job or anything....It was something new that i came across, wanted to try it,
    Play with it and give my best in it....... then i made a small "Hello World" application. It boosted my confidence......
    I started working on it more and more and more.......This was my feelings before and after selecting the project..... Though it was sad in the beginning....excited and surprising in he middle but it was totally best at the end..........
    Now wen i remember that day,,it brings smile on my face... I laugh for the way i searched and selected language.......
    hehehe.....
