Parsing Data For Fun , using Google App Engine Python

Hi ,

I just wanted to know about recent movies that are running in theaters near my location ,so i just wanted to create an alert that sends fb messages and sms frequently regarding the latest movie running in the theater near me.
To create this i used Google's App engine to create a python app witch is automatically invoked periodically as a Cron job .

Getting started with app engine using this link:
https://developers.google.com/appengine/docs/python/gettingstartedpython27/

I parsed the movies name by parsing the website  entertainment.oneindia.com and cron will execute the below script to get the movie name.....

import urllib

from google.appengine.api import mail

print 'Content-Type: text/plain'

print ''

try:

    url=urllib.urlopen("http://entertainment.oneindia.in/movie_listings/Bangalore+Lakshmi+Theatre.html");

    content=url.read()

    movie_name=content[content.find('25527878</td>')+13:content.find("<td class = 'm10' >10.00 AM")]

    movie_name=movie_name[movie_name.find("<td class = 'm10' >")+19:movie_name.find("</td>")];

    print "SMS notifier by vengad:Laskshmi theater:",movie_name

    mail.send_mail(sender="Lakshmi theater Information <fantastic.next@gmail.com>",

              to="Admin <vengadanathan@facebook.com>,Way2sms <2way2sms-for-sms-alert@way2sms.com>,friend <my-friend@facebook.com>",

              subject="Alert!!"+movie_name+" running on Lakshmi Theater tavarekere",

              body="""Hi ,

               Recent movie that is running on Lakshmi Theater tavarekere is """+movie_name+"""

               Report Generated by mail-alert App By vengadanathan""")

except:

    print "Sorry I was unable to retrive movie info"

The cron that i have created is

cron:

- description: movie alert

  url: /movie-alert

  schedule: every friday 12:00

so i will be getting movie alerts on every Friday Noon i.e the day new movies get released :)..
I added my friend's email id to the list so he will be also notified..

This app was created to eat time when i was alone in weekend without friends as a time pass...

Cloud Computing Experiments

I am quite interested towards cloud computing and tried to implement or do some projects in it , the first opportunity  which i got was to setup private cloud in my collage , so i tried using eucalyptus using Ubuntu 10.04 server edition which comes pre-installed as UEC (Ubuntu Enterprise Cloud) with ubuntu installation .

I followed

https://help.ubuntu.com/community/UEC/CDInstall

instructions to install the cloud .

By installing this i learnt a lot about cloud computing the various scenarios , pros and cons of all which i did .

Later i was asked to make use of a IBM Blade Server which is available in our premises effectively ,
for this i didn't chose UEC instead i have used PhpVirtualBox a web based front end for VirtualBox ,since it is a single bulk server and not consist of clusters i did not go for UEC, I then  installed oracle virtual box on the server and installed phpvirtualbox over lampp on that Server machine  .Then i installed Ubuntu Desktop as guest OS on that virtualbox , the instance can be launched anytime using the web interface anywhere withing the local area network covering the premises , the ubuntu instance has several scientific and num crunching  applications installed over it and it has VNC server installed over it , thus the Ubuntu Instance with a lot of application can be accesed via a web browser by any person with proper credentials with our college , so if any engineering faculty or student want to perform some computing task or need to use the computation software installed on the guest OS, he request the admin with the requirement , the admin then using the web based virtualbox interface selects the amount of RAM , No of Processors etc and lauches the instance , and the iIP address of the launched instance will be given to the corresponding faculty or student who have requested it and the faculty uses the IP address to access the instance via a Web Browser using VNC or SSH to the Instance and performs his required tasks  , after his work is over the admin suspends or power offs the running instance .

Then i have now planned of learning Open nebulae .

Trie using c

Hi ,  I just tried out implementing trie  data structure using c , however my first attempt is not much memory efficient .

here is the code

#include<stdio.h>
#include<stdlib.h>
struct node
{
char data;
int final;
struct node *next[26];
};
struct node *insert(struct node *root,char *p)
{
if(root==NULL && *p!='\0')
{
int i;
struct node *temp = (struct node *)malloc(sizeof(struct node));
temp->data = *p;
 
for(i=0;i<26;i++)
{
temp->next[i] = NULL;
 
}
 
root = temp;
if(*(p+1)!='\0')
root->next[*p-97] = insert(root->next[*p-97],++p);
 
}
else if(*p!='\0')
{
if(root->data == *p)
root->next[*p-97] = insert(root->next[*p-97],++p);
else
root->next[*p-97] = insert(root->next[*p-97],p);
}
return root;
}
 
 
void traversal(struct node *root)
{
if(root!=NULL)
{
int i;
printf("%c",root->data);
for(i=0;i<26;i++)
{
traversal(root->next[i]);
 
}
 
}
 
}
  
int main()
{
char *p = "testing";
struct node *root = (struct node *)malloc(sizeof(struct node));
struct node *root1 = (struct node *)malloc(sizeof(struct node));
struct node *root2 = (struct node *)malloc(sizeof(struct node));
root=NULL;
root = insert(root," ");
 
root = insert(root,"apple");
root = insert(root,"ant");
root = insert(root,"body");
traversal(root);
 
}
