Take Time to Create a Server Disaster Recovery Plan Computers Articles | June 9 Cheap Shaquille O’Neal Jersey , 2011
The office is in a panic, as there?s a major project due at the end of the week. The problem is the server just crashed. There is a backup installed, but it doesn?t seem to be working correctly or bringing up the right information. You called in a computer expert, but they can?t get there until later in the day.

This means everyone is at a standstill, so you finally send them all out for an early lunch break. Hopefully something can be done by the time they get back Cheap Vince Carter Jersey , because any more time and there could be some significant problems.

This scenario would be much different if you had a server disaster recovery plan in place. It means you have researched the various scenarios and have created the proper strategy for your business. It means assigning your information levels of importance, so you know which software to purchase for your business. It also means knowing which features are absolutely necessary.

People usually follow three different recovery plans, which is why it helps to know your data?s importance. A company should save their most important data on a second data center that allows you to gain access in mere seconds or only minutes. It is back on the computer before anyone notices it was missing. The next level of importance should be saved on a second data center that can be retrieved in only minutes or possibly hours. This is information that can be misplaced for a short time. The last option makes the information available in hours or sometimes days, but this data isn?t as vital to your company?s existence. While it takes some time to go through all of the information, it is a process you will appreciate later.

It helps to have a server disaster recovery plan in place ahead of time Cheap Tracy Mcgrady Jersey , even if it seems very complex, expensive, and sometimes very time-consuming. However, a person should consider these same factors once a server crashes, because all three of the traits would increase a great deal and could possibly even become unmanageable. It could put some people out of business or seriously hurt their profits. Then you would be wishing there was a plan in place. Instead Cheap Penny Hardaway Jersey , preparation and protection keep you calm when disaster strikes. You don?t have to call in the experts since they are already in place, because you have proper protection installed on your server.


Start Working With AngularJS


AngularJS is a Javascript MVC framework created by Google to build properly architectured and maintenable web applications.


AngularJS takes another approach. It attempts to minimize the impedance mismatch between document centric HTML and what an application needs by creating new HTML
constructs. AngularJS teaches the browser new syntax through a construct we call directives. Examples include:


Data binding, as in {{}}.
DOM control structures for repeating, showing and hiding DOM fragments.
Support for forms and form validation.
Attaching new behavior to DOM elements, such as DOM event handling.
Grouping of HTML into reusable components.


Why AngularJS?


AngularJS is an MVC framework that defines numerous concepts to properly organize our web application. Our application is defined with modules that can depend from one
to the others. It enhances HTML by attaching directives to your pages with new attributes or tags and expressions in order to define very powerful templates directly in your HTML. It also encapsulates the behavior of your application in controllers which are instanciated thanks to dependency injection. Thanks to the use of dependency injection Wholesale Orlando Magic Jerseys , AngularJS helps you structure and test your Javascript code very easily. Finally, utility code can easily be factorized into services that can be injected in your controllers. Now let鈥檚 have a closer look at all those features.


Feature 1: Two Way Data-Binding


Think of your model as the single-source-of-truth for your application. Your model is where you go to read or update anything in your application.



Data-binding is probably the coolest and most useful feature in AngularJS. It will save you from writing a considerable amount of boilerplate code. A typical web application may contain up to 80% of its code base, dedicated to traversing, manipulating, and listening to the DOM. Data-binding makes this code disappear Wholesale Magic Jerseys ,
so we can focus on our application.


Think of your model as the single-source-of-truth for your application. Your model is where you go to read or update anything in your application. The data-binding directives provide a projection of your model to the application view. This projection is seamless, and occurs without any effort from you.


Traditionally, when the model changes, the developer is responsible for manually manipulating the DOM elements and attributes to reflect these changes. This is a two-way street. In one direction, the model changes drive change in DOM elements. In the other Cheap Orlando Magic Jerseys , DOM element changes necessitate changes in the model. This is further complicated by user interaction, since the developer is then responsible for interpreting the interactions, merging them into a model, and updating the view. This is a very manual and cumbersome process, which becomes difficult to control Cheap Magic Jerseys , as an application grows in size and complexity.


There must be a better way! AngularJS鈥?two-way data-binding handles the synchronization between the DOM and the model, and vice versa.


Here is a simple example, which demonstrates how to bind an input value to an



element.
