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.

Learning the SQL by practising online - SQLZOO

SQL is standard language to access and manipulation data in MySQL and Oracle.

Although SQL is quite easy to learn and has limited syntax, but the concept of using mainly DDL (Data Definition Language) ,DML (Data Manipulation Language) and DCL (Data Control Language) take time to understand or to get accustomed to make use of  when it is required. (ref)

As far as , Learning SQL and grasping the syntax may be quite easy to begin with (lot of online resource are there) , but to get the required data for the  real world problem might be not that much easy and may require practice.

SQLZOO is website where you have opportunity to practice these problem, to sharpen your skill and to test what you have acquired. The best thing of this website , it support all type of database engine (Oracle, MySQL etc) and has many problem to practice.

Problem start with a scenario and will ask you to use specific DML , to get the required results.

Great website to start with your SQL training and hone your ability.
