To make a database backup using the MySQL command-line utilities, execute the following command:
$ mysqldump -u username -p –opt dbname > dump.sql
It will ask you for password because we used -p paramater over there. If the MySQL programs are not in your path, you will need to manually specify the location of the mysqldump program:
$ /path-to-your-mysql-bin/mysqldump -u username -p –opt dbname > dump.sql
Download the dump.sql and keep it in a safe place (CDR, Zip disk, etc).
If you need to restore your database, you can do so like this:
$ mysql -u username -p dbname < dump.sql
This is the simples way to restore and backup your database.
Since i am coding with codeigniter framework on gedit, i was looking for snippets for codeigniter on gedit
download gedit snippet for codeigniter
By the way if you want to make your gedit more useful for programming surely you may add some third party plugins as many as you want or simply just active default plugins. Idea is that firstly download a plugin then extract its content to ‘~/.gnome2/gedit/plugins/’ directory. Once you have installed the plugin you want, you need to enable it via Edit>Preferences and then the Plugins Tab. Such as;
- Class Browser
- Bracket Completation
- Character Map
- Embedded Terminal
You can basicly find out third-party plugins by clicking on this link
This is a wonderfully informative Amazon update based on Joachim Rohde’s discovery of an interview with Amazon’s CTO. You’ll learn about how Amazon organizes their teams around services, the CAP theorem of building scalable systems, how they deploy software, and a lot more. Many new additions from the ACM Queue article have also been included.
Amazon grew from a tiny online bookstore to one of the largest stores on earth. They did it while pioneering new and interesting ways to rate, review, and recommend products. Greg Linden shared is version of Amazon’s birth pangs in a series of blog articles.

More than 55 million active customer accounts.
More than 1 million active retail partners worldwide.
Between 100-150 services are accessed to build a page.
What is it that we really mean by scalability? A service is said to be scalable if when we increase the resources in a system, it results in increased performance in a manner proportional to resources added. Increasing performance in general means serving more units of work, but it can also be to handle larger units of work, such as when datasets grow.
The big architectural change that Amazon made was to move from a two-tier monolith to a fully-distributed, decentralized, services platform serving many different applications.
Started as one application talking to a back end. Written in C++.
MVC Architecture has implemented by Trygve Reenskaug at 1979 for the first time. It was implemented on Smalltalk at Xerox labs. Then benefits and advantages of this architecture has been accepted by most of the coders and software engineers.
It was an information about MVC’s history above. Now lets talk about what really MVC is. What do you understand from MVC. The word M stands for Model, V stands for View and C stands for Controller. I am going to mention about each item.
The figure above may help you while thinking what structure it might have. Let’s start with Model.
It handles data processing and database works part. Model processes events sent by controller. After processing these events then it sends processed data to controller (thus, controller may reprocess it) or directly to view side.
View prepares an interface to show to the user. Controller or model tells view what to show to the user. Also view handles requests from user and informs controller.
Let’s say you are using some other libraries as well, there it goes, jQuery is such a good friend with other libraries. API designed with conciseness and convenience as the driving factors.
Before start with jQuery i want you to know some basics about it. You can download the framework basically from www.jquery.com then download it on your desktop. This is how jQuery places in html code.
<strong>// Your code goes here</strong>
You can start with placing your core *.js file which is jquery.js for this example.
