Escape or Encode the character using javascript or ruby

Guys,

          When we are storing the data in the database using any encoding method like UTF-8 and retrieve data in javascript it gives us in output in decode and unescape format.

To solve above issue using javascript or ruby

Javascript functions:
escape(String) - unescape(String)
encodeURI(String) - decodeURI(String)
encodeURIComponent(String) - decodeURIComponent(String)

Ruby methods:
CGI.escape(String) - CGI.unescape(String) or CGI.unescapeHTML(String)
URI.escape(String) - URI.unescape(String)

Online tool for escape/unescape, encode/decode the character.

Avoid the memory blockage during large xml request

Guys,

        When i am playing with handling the xml request through net::http discover the problem of memory blockage and just worried about how to handle that. This problem happen b'coze i have bulk of xml data in the request. So, i form the one of the solution by using the block of net http.

When we using the block of net::http. It yields each fragment of the entity body in turn as a string as it are read from the socket.

Lets we consider 2 scenario:

require 'rubygems'

require 'net/https'

require 'uri'

uri = URI.parse("http://google.com")

http = Net::HTTP.new(uri.host, uri.port)

case 1:
response = http.post('http://google.com', 'query=language')

case 2:

# using block

   File.open('test.txt',  'w') { |f|

      http.post('http://google.com', 'query=language') do |str|

          f.write str

       end

   }

In case 1 it loads the entire response in memory. While in case 2 it read each fragment and write into file. so when we use block it's avoid memory blockage.

Hope above post will help you to avoid memory blockage and increase performance.
