Perl and selenium - a trail of youtube history

Recently I wanted to to get complete list of the youtube history page to a video I have seen a long time back. Though Youtube save ur maintain ur history but does not provide the option to search your history. The history button provided shows very few videos at time.

So I decided to write my own script recipe to handle this scenario. Though I have know about selenium for along time but never tried it Perl API. Let see it this can help me to get my list.

 Before reading this script recipe u need to check some info video and slide share get the functionality and usage the module (ingredient) we will going to use 

The ingredient
1. Selenium
2. Perl (U can use Java etc)
3. XPath
4. XPath Checker (addon) (this will make ur task easier to write ur regular expression of xapth) (U can get the introduction of Xpath on w3school tutorials)

Now U are ready to start to make ur own ingredient and do a bit fun.

To be continued...

flock - All u need to know abut file locking in perl

Some times we need control over  read and write over files operation. File locking comes for rescue.

Though Perl provide many function to control over  file locking operation. I found flock function is the best.

Perl monks has a great tutorial for flock and operation and usage . Simple usage  and operation number and their meaning.

  sub LOCK_SH { 1 } ## shared lock
  sub LOCK_EX { 2 } ## exclusive lock
  sub LOCK_NB { 4 } ## non-blocking
  sub LOCK_UN { 8 } ## unlock

RESTfull Love service Triangle

Hi All ,

 Today I will be writing little about RESTful api (Represntational state transfer) , kind of web service.Now day every  application (generally mobile application) and good website will provide one
of these services to the programer to interact more and develop application on top of it.

 So to start with REST u should be knowing these 3 terms (mug it) (also REST triangle)
1. noun

In rest , noun is URL identifier (eg. www.example.com ).
Verb   is the action to be taken HTTP request method eg GET to read , POST to create, PUT to update and DELETE to delete.

Why I have started prefering viber over skype on my linux box for messaging!!

Recently , I installed the viber on my linux machine (ubuntu 14.04) for my development box just enthusiastically and found the above my expectation  as compared  skype linux version.

Lets begins with the login , where I used my mobile no and it automatically synced my login to mobile contact. So for now onward I am getting into habit of messaging my friends on viber in place of whatsapp. That is a huge gap in skpye,  which identification element is your mail/ facebook login.

Next comes the gui, the gui of viber for the linux flavour is more friendly intuitive. I do not think any one will disagree on this (again I will highlight I am the linux version).

What left me in miserable state while using viber was about the call quality. I cant neither hear sound or my mic is working for viber , that is not the case for skype. (bug)

 Hope , viber development team will soon be resolving these issue.
