Importance of Back-End Web Development

While creating a new website, developers have to focus on both frontend and backend development. The frontend of an application refers to the code that is visible to the website visitors. Normally, frontend code creates interfaces through which the application interfaces with the users. On the other hand, the backend code interfaces with the server, and deliveries content or data to be displayed to the users. So the backend code deals with the application as well as the web server and database. The combination of application, server and database makes the backend coding both complex and important.

Why Developers Must Pay More Attention to Backend Web Development?

Facilitates Information Exchange

As noted earlier, backend consists of three key elements of a website, ie, application, web server and database. While accessing the user interface of a website, each user is required to provide his login id and password. The login id and password provided by the user is validated by the backend. Likewise, any information submitted by the user is stored in the databases through the backend code. Also, the backend retrieves information from the database, and sends the information to the user interface for displaying to the user. Here, the backend of a website acts as its structure and facilitate information exchange.

Runs in Various Environments

Nowadays, businesses deploy websites and web applications in a number of environments. For instance, some enterprises prefer running websites on web servers, while others deploy web applications in the cloud. At the same time, many businesses even combine both hosting options to avail benefits like enhanced performance and scalability. The web server setup varies from one network to another. Also, the programmers often distribute server-side workload over multiple machines. The varying hosting environments make it essential for developers to customize the backend of websites.

Contains the Application Logic

Most programmers nowdays keep the user interface and application logic of a website separate to simplify its development and maintenance. In addition to including the domain and infrastructure components of an application, the application logic also implements the routine data processing required by each business. The backend of a website contains its application logic. Here, the developers must focus on backend web development to switch from one frontend to another seamlessly, and make multiple user interfaces access the same application logic.

Adds Utility to Each Frontend Functionality

While developing a website, programmers are required to write backend code to add utility to each frontend functionality. For instance, they have to write code using a server-side programming language to add functionality to a user login form. Each time a user enters his login credentials, the backend code will collect the values, and compare them with the login data stored in databases. Likewise, backend code also adds functionality to various forms, profiles and accounts. Here, no website can function without quality backend code.

Impacts the Website's User Experience

The usability and user experience of a website impacts its popularity in the longer run. As noted earlier, all tasks required to make a website function are performed at the backend. So the user experience delivered by a website will be impacted by the quality of backend code. Any issues in the backend code can result in frequent website crashes, running the website slowly, and similar performance issues. At the same time, minor defects in the backend code can make the website vulnerable to targeted malware and security attacks. It is important for the developers to focus on the quality and structure of the backend code to make the website deliver richer user experience without any interruptions.

It is also important for the developers to effectuate backend web development by picking the right programming language and framework. As they have option to choose from many server-side programming languages, the programmers must pick the language that meets all needs of the project. Likewise, they also need to pick the right web development framework and tools according to the specific server-side programming language.

How to Keep a Woman Emotionally Attached to You Forever

A lot of guys mistakenly think that some girls are out of their league due to their beauty. Many guys also mistakenly think that girls who look like supermodels are only after their male and muscled counterparts. This is hardly ever the case, though.

Girls actually care about personalities more than looks. So, as long as you are confident and bold enough to walk up to a gorgeous girl, you definitely stand a chance. However, confidence and boldness alone might not get you all the way. Because of this, you should know these powerful techniques of seduction to guarantee that your girl of choice falls in love with you.

How To Make Girls Attached To You – 3 Hardcore Techniques Of Seduction

Technique Number One: Eliminate those insecurities. To make gorgeous girls long for you, you need to make them feel like you are worthy of them. This can only be done if you believe that you are, too. If you have any doubts in your abilities, a girl will be able to pick up on those doubts and you will have ruined your chances to be with her. Therefore, you need to build up your confidence first and get rid of every weakness in your bones before anything else.

Technique Number Two: Deceive her. This might sound a bit weird, but deception happens to be a very effective tool when it comes to seduction.

Girls respond to seduction more when they are totally confused, so if you seem a bit vague and mysterious, you can turn girls on. Simply keep your actual intentions a little unclear to truly keep them intrigued.

Technique Number Three: Build emotional bonds with her. Girls are emotional creatures, so you need to make lasting impressions by getting in touch with female emotions.

There are particular techniques you could use to help get this emotional connection going and make things easier for you in seduction. By learning such techniques, you can be guaranteed to succeed in seducing your dream girl.

One such emotional connection builder tactic, called fractionation, is invented by the underground seduction community using techniques from Neuro Linguistic Programming (or better known internationally as NLP) and hypnosis. However, you will not need to be a master hypnotist or someone schooled in NLP for years in order to pull it off.

Fractionation, which comes in an easy-to-follow two-step formula, is known to be able to create stalkers out of otherwise sane women. It is known to be a covert tactic because it accesses a woman’s “hidden” psychology triggers through simple conversational tricks. With the formula, a woman will immediately feel that she is connected with a man emotionally, and will often end up doing things that he asks her to do.

How to Send Free Text Messages On Your Iphone Using the Safari Browser

If you are like me, then you text message on a daily basis and you consider it more of a necessity rather than just an option on your Iphone. I don’t know what it is, but text messaging or texting is really, really addicting and easier than making a phone call.

The only problem with text messaging is it can get very expensive, very fast and before you know it, you are over your wireless plan’s limit. At the beginning of the month or billing cycle for your iphone, you say to yourself, “no way am I going to text over 200 times this month”, but low and behold, a month down the road you get your bill and you have used 350 text messages. That is 150 over the 200 text messages you get with the Iphone’s AT&T standard plan, that is 150 extra text messages at 10 cents a piece which makes your bill $15 dollars or more than it has to be.

That can really make a dent in your wallet if you don’t get your text messaging under control or find an alternative, and if you are an avid text messenger like I am, you know that once you get in the habit of use text messages instead of making phone calls, you do it more and more often. Actually, text messaging has become so popular that vocal conversations over cell phones have become a distant memory or the second option to send text messages.

As the avid text messenger and penny pincher that I am, I was destine to find a way around paying for going over my text messages and I didn’t want to alter my wireless plan and pay more money, so I did some research and found this website Joopz.

This website, which you can access through the safari browser on your Iphone, will allow you to send free text messages which can save you lots of money depending on your how much you use text on a monthly basis.

Scrapbook Page Ideas – How To Create An Out of Bounds Layout

Creating an Out of Bounds layout can really make your scrapbook page ideas POP! and be more exciting to the eye.

The basic idea of ​​an Out of Bounds or OOB (if you follow the scrapbooking forums) layout is by making part of a photograph stand outside a frame.

Here's my simple technique for creating you own Out of Bounds scrapbook page layouts.

  • First of all choose a photograph that has a main focal point like a head and shoulder portrait.
  • Open up your scrapbooking software program. I use Photoshop but most of the software packages out there can achieve the same results by adapting these steps to suit.
  • To begin you'll need a background paper, a frame and at least one photograph.
  • Place the frame above the background as a separate layer. Then underneath the frame add your photo also as a separate layer.
  • To clarify you should now have a background paper, a photograph and a frame.
  • You'll need to resize the frame or the photo so that the frame is smaller than the photograph.
  • Position the frame so that part of the photo layer is outside the edge of the frame. This is going to help achieve your "out of bounds" scrapbook page layout .
  • Create a layer mask on the frame layer and start removing the edge of the frame where you want the edge of the photo to pop out.
  • You'll also need to add a layer mask to the photo layer so that you can remove the surrounding area.

And that's it, once you have masked out the layers your photo should look like it's popping out of the frame.

I find a successful Out of Bounds layout will keep some of the original background inside the frame and adding a drop shadow to the photo layer really helps create a 3D effect.

Ways To Learn Coding IOS Apps

There are tons of great ways out there to learn iOS these days. The great thing is that most of those resources are free and available instantly online!

In the early days, the only resources out there were books that you had to buy and read through. In fact, that's how I learned iOS. I would not recommend learning this way today because one of the greatest learning resources available today are the Stanford iPhone Programming Course videos that are free on iTunes. There are about 50 videos and they are basically the course lectures taped and provided for free so that you can download them and watch them as if you were sitting in the classroom at Stanford University!

Even with this great resource, make sure that you do some actual coding and practice exercises through watching the videos. When I learned iOS development, I read through the whole book from front cover to back and realized that when I sat in front of the keyboard to write code, I did not know where to start!

Just like reading the book front to back, if you watch all the lectures without ever doing any exercises, you will not absorb the material and at the end of the lectures, you'll have a deceiving confidence in yourself.

Only when you sit down in front of XCode (the development environment where you write code to build iOS apps), you'll realize that watching video lectures is not the same thing as actually doing the coding!

The other thing you may consider are YouTube videos where people teach you how to code. The thing to beware of, however, is incomplete video series or videos where the author does not teach and only tells you what to click or type. In that case, you're not really learning; sincerely following a recipe.

Lastly, Apple also provides great tutorials and quick starts for new developers. Once you sign up as an Apple iOS developer, you'll have access to these resources as well as their developer forums where you can ask and answer questions.

The most important point, no matter which method you choose to use, is to practice and fail fast; because only through failing and practicing will you grow and learn! Do not worry if you do not know everything yet. The best way I found to learn was actually to start coding and then when I encountered something that I did not know how to do, I would just search for how to do it online and integrate that wisdom into my repertoire.

Soon enough, you'll be building your own applications and turning your app ideas into a reality!
