Understanding the differences between Illustrator and Photoshop 
can range from confusing to downright frustrating for those who are 
new to graphics and image editing. Which application should you use
for your project? Should you use a combination of the two together, or 
just stick with one? Having a household name as Photoshop does, many people 
simply turn to Photoshop for all their work, but that may not be the best 
choice for all your graphics work.

It really boils down to having an understanding not only of what you wish to achieve, 
but also having a firm grasp on the key differences between Photoshop and Illustrator;

When building a custom web application you need to consider the type of database that best suits the data. 
Here's a quick guide on the differences between MySQL (Relational) and MongoDB (Non-Relational / NoSQL).

###Data Representation
-MySQL represents data in tables and rows.
-MongoDB represents data as collections of JSON documents.
If you think about it, a JSON document is very much like what you would be 
working with in your application layer. If you are using javascript, 
it's exactly what you're working with. If you're using PHP, it's just like an associative array.
If you're using python, its just like a dictionary object.

The solution:


    The two tables must have the same engine i.e. ENGINE=InnoDB. (can be others: ENGINE=MyISAM works too)
    The two tables must have the same charset.
    The PK column(s) in the parent table and the FK column(s) must be the same data type. (if the PRIMARY Key in the Parent table is UNSIGNED, be sure to select UNSIGNED in the Child Table field)
    The PK column(s) in the parent table and the FK column(s), if they have a define collation type, must have the same collation type;
    If there is data already in the foreign key table, the FK column value(s) must match values in the parent table PK columns.
    And the child table cannot be a temporary table.

Dig (domain information groper) е програма за Linux също както е nslookup за Windows. Тя е малко по мощна. Тук са описани някои възможности за използването и, заявки към различни nameserver-и, заявки към специфични записи на nameserver (A, AAAA, MX, CNAME, TXT) и други.


Инсталиране на dig

Ако работите с Red Hat базирана дистрибуция (centos, fedora, red hat), може да използвате yum:

yum install bind-utils

За всяка Debian базирана е apt-get:
