NoteMonk

For example I need to cover all the stuff belongs to the Triangle which is belongs to the Mathmatics Class-9 e-Book So if I want to finish that book it may takes 3-days of time for single glance but if I go through the http://www.notemonk.com/node/2584/Angle.Sum.Property.of.a.Triangle/ I finished in very less time because there they are providing the stuff in video tutorial.

Understanding the conclusion is better than reading from beginning and understanding that stuff, I think these Notemonk guys understand one universal truth that is “Don’t try to reinvent the wheel” .

So try this processed content save your time and increase your strength of the topic.

Ok ok he is making fun about Asian countries but it might make bad opinion about  Asian countries, I never likes to point out others mistakes and problems, to judge a mistake we need to analyze more on the situation.

Anyway he is the real comedy king, Very very funny fellow.

Code:

import gdata.youtube
import gdata.youtube.service

client = gdata.youtube.service.YouTubeService()
query = gdata.youtube.service.YouTubeVideoQuery()

#query.vq = “2005 telugu full movie”
query.vq = “yogi telugu full movie”
query.max_results = 50
query.start_index = 1
query.racy = “exclude”
#query.format = 5
query.orderby = “relevance”
feed = client.YouTubeQuery(query)
resultsCount = int(feed.total_results.text)
print “Debug0: “,resultsCount
i = 0
while resultsCount > int(query.start_index):
print “Debug1:”
print “\n The total results for the given query: “, feed.total_results.text
for entry in feed.entry:
duration = int(entry.media.duration.seconds)
#print “count: “,i
i = i + 1
if duration > 500:
print “************ start *************”
print “URL: “,entry.media.player.url
print “Duration: “,entry.media.duration.seconds
print “Title of the video: “,entry.title.text
print “************ End  **************”
query.start_index = int(query.start_index) + int(query.max_results)
feed = client.YouTubeQuery(query)

There are many issues to consider when we write a crawler program in that getting total number of results for our query and pagination etc… These two are solved very easily by gData’s well implementation.  For more info about gData python. Even we can log into the youtube through gData and can create, edit and update the Youtube data.

Regular Expressions in Dos:

1. open dos and type cd \

2. cd docu*, press Enter

3. In findstr(dos command ) /R attribute is to use Regular expression mode

Regular Expressions in c++:

RegEx Engine is implemented through RegExpr Class.

Code:

       RegExpr re;
       re.compile("a*(cb|c*)d");

Regular Expressions in Visual C++:
The Visual C++ also implements the RegEx Engine with RegEx class.

Code:
     #include <regex>
     basic_regex<char> regex("[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}"
           ,basic_regex<char>::icase);
     cout<< std::boolalpha
           << regex_match("GoOD@DOMAIN.COM", regex)<< std::endl;

Regular Expressions in Java:
Java uses   java.util.regex Package for pattern matching, even we can use regular expressions on
String class for splitting and matching desired data. For more examples we can visit
sun web site RegEx doc

code:

 Pattern pattern = Pattern.compile(console.readLine("%nEnter your regex: "));
 Matcher matcher = pattern.matcher(console.readLine("Enter input string to search: "));
 matcher.find()

Even all scripting languages are providing RegEx Engine for on fly Data processing.

Regular Expressions in JavaScript:
We can execute regular expressions in JavaScript with RegExp.exec function,
Here RegExp means an expression

Code:
  /s(amp)le/i.exec("Sample text")

Regular Expressions in Python:
Python provides RegEx Engine with re package.

Code:
   import re
   p = re.compile('[a-z]+')
   m = p.match( 'tempo')

Even for more information Python re.

Regular Expressions Usage in DataBase Queries:
We can embed Regular Expressions in the Database Sql queries, like this
 Query:
    SELECT description FROM testTable WHERE REGEXP_LIKE(description,'[mn]');
 click Here for more support

RegEx usage minimizes lot of work for Data processing but we should be very careful at usage,
we should minimize the usage of RegEx other wise it may effect on Project maintainance we should
write a comment for every part of the expression other wise in the future it takes more and more
time for modifications in the RegularExpression 

The below links are helpful for checking Regular Expressions in on-line.

For python I added the below text to the .vimrc file. .vimrc is located at ~/.vimrc(Home directory).

set term=builtin_ansi
syntax on
autocmd BufRead *.py set smartindent cinwords=if,elif,else,for,while,try,except,finally,def,class
autocmd BufRead *.py inoremap # X^H#
autocmd BufRead *.py set tabstop=4
autocmd BufRead *.py set shiftwidth=4
autocmd BufRead *.py set smarttab
autocmd BufRead *.py set expandtab
autocmd BufRead *.py set softtabstop=4
autocmd BufRead *.py set autoindent
autocmd BufRead *.py highlight BadWhitespace ctermbg=red guibg=red
autocmd BufRead *.py match BadWhitespace /^\t\+/
autocmd BufRead *.py match BadWhitespace /\s\+$/
set incsearch
set ignorecase
set num
set history=1000

Now I am getting smart indentation for conditional blocks, loop blocks and even for classes and methods .

In Python we can handle the proxy with urllib2 package, so if we look deep into the program urllib2.ProxyHandler and urllib2.HTTPBasicAuthHandler functions helps for authentication.

Code:

import urllib2
from lxml import html

proxy_handler = urllib2.ProxyHandler({’http’: ‘http://www.ragalahari.com/wallpapers.asp’})
proxy_auth_handler = urllib2.HTTPBasicAuthHandler()

Now we need to append our User Name,Password and Proxy Name to the realm.

Code:

proxy_auth_handler.add_password(’realm’, ‘Proxy Name’, ‘User Name’, ‘Password’)

opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)

opener.addheaders = [('User-agent', 'Mozilla/5.0')]

wxPython is a cross-platform GUI API, it is very simple and easy to develop a GUI Application by using wxPython API. It has rich wxWidget component set for building forms,  only we need to understand how to use them for our application need. In programmers view really this is very flexible API, rapidly we can develop forms with minimum effort and with minimum time factor.

Now we start comparison
