Principles of Modern Web Development

There has been a recent debate regarding whether a web developer’s speed is equal to productivity. Depending on the interpretation, there is bound to be opposing viewpoints with regards to this. However, the productivity of a developer should be equated to whether the project was completed in time but more importantly whether the application is usable. From the analysis, it is obvious that how soon a web development project is completed depends on several factors such as complexity, functionality and the scale of productivity. If you decide to hire a web developer, ensure that the web experts understand the modern day web world.

Understanding Modern Web Development

In order to create quality applications, such applications should be made from a user’s point of view. Creating an application based on how complex or easy it will be for the end user to use the same application ensures that a developer can pre-empt any challenges that the user is likely to face. The assumption here is regarding how the user will interact with the application.

Mobile approach

Today, smartphones are one of the fastest growing phenomenon due to the increasing numbers of smartphone users. The most recent statistics suggest that approximately 64% of all mobile users across the world use smartphones. This figure is increasing by the day. The emerging trend of smartphone in use should be incorporated in modern web development in such a way that applications can be used in multiple devices including mobile devices as opposed to the traditional approach where applications were created for single devices. This means that a web application built for computer use should function just as well in devices such as tablets and smartphones. In fact, the best approach in modern development is that applications should be first be built for smaller devices before proceeding to PCs functionality.

Web Technology Stack Utilization

Due to the advances made in the field of information and technology, web developers have a vast resource of modern web technologies at their disposal. Despite the fact that experimenting with new technology to develop websites and application is a good approach, a good developer should stick to tested solutions in development. You will perhaps not want to be the person who creates a complex web application using a non-tested but modern technology that will never work effectively on the application. Unlike in the past, modern web development also dictates that a developer avoids technology that hinder agility. Web developers often find themselves having to balance between applications that are both portable and agile. It is no longer a viable approach to create an application that can only be used on a single database or platform.

Great User Interface

Well-designed interfaces can sell anything as they are more appealing to the users. However, the appeal should not be equated to complexity as most users avoid web applications that are not easily navigable.

Conclusion

In order to create successful web applications, developers are required to maintain the standards within the industry while at the same time observing the emerging trends in modern web development. The end products should be adaptable meaning that a good web application can be used both in the present and the future without any alterations being made.

Know The Steps Of A Successful PSD To WordPress Conversion

Designing a WordPress website is easier. One just has to acquire a bit of programming knowledge, as the open-source platform is extremely user-friendly. However, you need to convert your PSD templates into WordPress themes to create eye-catching web pages. Now, the big thing is, there are some finite steps that you have to follow for a successful PSD to WordPress conversion. Many people hire designers or WordPress experts for the same. So, let us have a glimpse of the essential steps.

Slice your PSD template

The process of PSD to WordPress conversion starts with cutting the PSD template into multiple files. This let you save each design component of the PSD template perfectly. You can use an image editing software or the very popular Adobe Photoshop for the same.

Create an HTML & CSS template

You need to code the sliced images into HTML format and then into a corresponding CSS template. You can use software like Dreamweaver or Fireworks to escape the need of programming skills. However, bit knowledge of HTML and CSS turns helpful in this step. Save the HTML template as index.HTML and the CSS file as Style.css. In this step, you can decide whether you will love to create a responsive website or not.

Break index.HTML file into a WordPress structure

A WordPress theme has a specific structure and mainly comprises of two types of files -index.php and style.css files. You need to break the index.HTML file into several .php files like the following ones.

• Archive.php

• Header.php

• Footer.php

• Index.php

• Single.php

• Page.php

• Sidebar.php

• Category.php

• Search.php

• 404.php

• Comments.php

• Comments-popup.php

This helps in adding the additional functionalities and the plugins in a hassle-free manner.

Add WordPress tags

In this step, you have to add in-built function tags to the .php files that you have created in the previous step. This completes the creation of a custom WordPress theme. You can activate it via the WordPress dashboard.

Add functionalities

As it is always better to improve yourself, you can add more functionalities as per your requirement in the last step. The process of conversion of PSD to WordPress is simple, but if find it a bit confusing, hire a WordPress developer. You can easily find one at an affordable rate, as there is no dearth of experienced WordPress developers. Moreover, you can find many free tutorials over the web on PSD to WordPress conversion for more information.

CPU Maxes Out and Utilization Never Goes Down

Have you ever encountered circumstance where your applications CPU maxes out and never goes down even if traffic volume goes down? Did you had to recycle to JVM to remediate the problem? Even if you recycle the JVM, does your CPU start to spike up after some time?

This type of problem surfaces because of one of the following reasons:

Repeated Full GC

Non-terminating Loops

non-synchronized access to java.util.HashMap

Let’s see how to diagnose these scenarios and address them.

Scenario 1: Repeated Full GC

Full GC is an important phase of Garbage Collection process. During this phase, entire JVM is frozen, every single object in the memory is evaluated for garbage collection, naturally, it turns out to be a CPU intensive operation. If application happens to have memory leak, then “Full GC” will start to run repeatedly without reclaiming any memory. When ‘Full GC’ runs repeatedly, CPU will start to spike up and never come down.

Tactical Solution: To resolve the problem completely, memory leak in the application has to be fixed. Resolving memory leaks might take some time. (Of course it goes without saying, you can engage experts like me.to resolve it quickly). Until then below mentioned tactical solution can be implemented to keep the application functioning in production. You need to instrument a script which would monitor garbage collection log file of the application for every 2 minutes. If the script notices more than 3 ‘Full GC’ runs in a 10-minute window, then that particular JVM should be decommissioned from taking production traffic. JVM should be recycled after capturing thread dump and heap dump. After recycling JVM should be placed back to take active traffic.

Strategic Solution: Using the Heap Dump/Thread Dump root cause of the problem should be identified & fixed.

Scenario 2: non-terminating loops

Sometimes due to bug in your code or in the 3rd party library that you use – loop constructs (while, for, do.while) may run forever. Consider the scenario below:

Due to certain data condition or bug in the code, ‘myCondition’ may never get satisfied. In such scenario, thread would be spinning infinitely in the while loop. This would cause the CPU to spike up. Unless JVM is restarted, CPU maxing out wouldn’t stop at all.

Solution: When you observe CPU maxing out and utilization not coming go down, you should take 2 thread dumps in a gap of 10 seconds between each thread dump – right when problem is happening. Every thread in “runnable” state in the first taken thread dump should be noted down. Same threads state in the second thread dump should be compared. If in the second thread dump also those threads remain the runnable state within the same method, then it would indicate in which part of the code thread(s) are looping infinitely. Once you know which part of the code is looping infinitely then it should be trivial to address the problem.

Scenario 3: non-synchronized access of java.util.HashMap

When multiple threads tries to access HashMap’s get() and put() APIs concurrently it would cause threads go into infinite looping. This problem doesn’t happen always, but rarely it does happens.

Solution: When you observe CPU maxing out and utilization not coming go down, you should take a thread dump – right when problem is happening. You need to see which are threads that are in “runnable” state. If that thread happens to be working on HashMap’s get() or put() API, then it’s indicative that HashMap is causing CPU spike. Now you can replace that HashMap with ConcurrentHashMap.

4 Inherent Qualities to Consider in Your App Development Partner

With the advent of smartphones, the business world have laid special emphasis on development of highly impressive mobile applications. Noticeably, the ever-growing interest in mobile applications has driven a mob of tech-minded folks into the domain of app development. Mobile application development companies are trying to develop the next trendsetting mobile app and to earn a dearer paycheck. However, keep note of the fact that; not all service providers come with the same level of skill set and ability.

Thus, while looking for an expert be sure to note that the professional boasts some inherent qualities. Here are some of the must-have attributes.

Experience

Mobile app development is certainly dynamic and thus, you require a skilled expert who is capable of adapting fast with the dynamic technological and business environments. Becoming an application developer needs a lot of learning, work and research. Only academic qualifications don’t count as because, the app developer must showcase a rich portfolio as well to prove his level of competence.

Familiar with Market Needs

With the launch of many mobile applications coming every other day, a mobile application developer must boast in-depth understanding of the industry. The app developer must emphasize on understanding the client’s needs and build the app as per their expectations. Creativity is a prime factor as because, this entire process is all about converting the creative ideas into trendsetting applications.

Profound and Language Knowledge

Profound understanding of multiple programming languages is a prime quality of good app developers. Language is the main tool of trade of developers and thus, the developer must show ability and competence to build applications with ease. Experience in working on these mobile platforms like iOS, Android, Blackberry and others is also quite crucial.

High level of integrity

Integrity demands that agreement between the developer and client is binding. But, this is not the ideal case at all times, as because, some developers duplicate the apps and sell them to other customers even after transferral of rights to the clients. This phenomenon is certainly unacceptable and unethical. Thus, with the aim to avoid of these, clients must always demand references along with the portfolio.

App developers must strive to deliver an impressive user-friendly app while keeping the end-user in mind. Though, there are many qualities to define an expert, but it is certainly the ideal choice to consider these aforesaid qualities for choosing a mobile application development partner.
