Ruby on Rails vs Django – Which framework is best for 2020

In the programming world, there are many web development frameworks available to developers, but as we all know, Django and Ruby on Rails work best. They are emerging as the popular web frameworks and this popularity is suspected to continue until 2020.

Ruby on Rails Vs Django Both are the right frameworks for web development — but how do you choose one over the other?

What they have in common extends from programming language similarities (Ruby for Rails and Python for Django), both of which are object-oriented and dynamically typed and their performance, which is specific to each project.

If you are trying to decide between the two, both Django and Rails are good choices — here are some things to think about that will help you make the right choice.

What is Django?

Django was released in 2005 and is a Python-based web framework and a primary choice for Python app development as well. What makes it so popular is that it is a general, open-source and free framework, which makes it easily accessible. Features at Django are very famous by developers. It was designed to simplify the process of creating complex and database-driven websites. This framework encourages rapid development with a stylish and pragmatic design.

Pros of Django Framework

• Scalable
• Mature Software with numerous Plug-ins
• Highly Customize
• Effective Admin Panel
• Django has the Representational State Transfer (REST) framework
• Adopts Battery-included approach
• Supports MVC programming
• High compatibility with databases and operating systems

Cons of Django Framework

• Lacks the capability to handle multiple requests simultaneously
• Highly reliable on ORM system
• Makes web app components tightly-coupled
• Too Monolithic

What is Ruby on Rails?

Written under MIT license, Ruby on Rails, abbreviated as RoR is a server-side, open-source web app framework. Rails is a model-view-controller and provides fantastic standard structures for a database, web services, and pages. It is considered a time-saving method for developers to write code.

This framework works mainly on two principles — DRY (Don’t Repeat Yourself) and Convention Over Configuration. The former is self-explanatory eliminating the need to perform the same task of coding over and over, while the latter means that the environment you work in, such as systems, libraries, languages ​​and more, allows many logical situations by default. This means that you can adapt to them instead of creating your own rules every time, which makes the whole programming process much easier.

Pros of Ruby on Rails

• Easy to modify and migrate
• High-speed development
• Diverse tools and presets
• Superior testing environment
• Active RoR community
• The component structure is based on Plugins and Gems — enabling high functionality with less coding.

Cons of Ruby on Rails

• Tricky to create API
• Varying quality and standard of documentation
• Low run time speed
• Lack of flexibility

The difference between Django and Rails Framework

Language: While Django uses Python, Rails is developed with Ruby, introduced in 1995. Python is one of the best programming languages ​​and is known for emphasizing the code’s clarity and readability, while Ruby is known for its attributes such as flexibility and freedom and also for its understandable syntax.

In addition, Python is the easiest programming language to learn and write quickly. There are different types of applications that can be developed with Python.

On the other side of the table, Ruby was designed with the emphasis on “enjoying” writing the language, so it’s basically fun. Although the applications built with any of them will look and work almost exactly the same, the biggest difference can be seen under the covers.

Architecture: One thing that both web development frameworks have in common is that both have adopted Model-View-Controller (MVC). For Django, however, it is called Model View Template. Both MVC and MVT are broadly similar and differ ever so slightly.

In Django, the model represents the database that describes the data structure, View is the common expression – based URL Dispatcher that controls what users see. Last but not least, a template means a web template system merged with Django Template Language (DLT). The controller part here is managed by Django himself.

With regard to Ruby on Rails, the model specifies the database data such as comments, images, posts etc. All this is taken care of by ActiveRecord. Here the view covers the data in the HTML template and then sends it to the Controller, which is later managed by Active View. Now Action Controller is the one to connect the model and view and manage requests while taking care of sending responses to the web browser.

User interface: When you make Django vs Ruby on Rails comparison based on the user interface, they are both absolute winners. That’s because both are created to offer a high-quality experience. These web-centric frameworks allow any app development agency to develop highly functional websites loaded with impeccable plugins and add-ons.

Speed ​​and performance: In the battle of Ruby on Rails Vs Django, it is observed that Rails is 0.7% faster. That’s because Rails has the advantage of a rich archive of fantastic libraries and plugins to improve speed and eventually the performance of this framework. Still, Django encourages equally fast development processes and is an incredible choice for a web framework.

Django REST framework provides convenience in the form of authentication modules, JSON series / deserializers, etc. When comparing Django to RoR we can say that Django can have an advantage because REST is one of the prominent advantages of Django.

Nevertheless, the performance of Django vs. Rails is high for both as they utilize modern programming languages ​​while providing the tools to optimize the code

Stability: Creativity and stability are two parallel elements necessary for development. We can consider the winner who can handle both effectively. Ruby on Rails has the ability to juggle both as it allows users to reuse the code to minimize dependencies. It also uses the convention of configuration modes and frees the coders from any further efforts.

On the other side of the table, Python practices a more conventional approach by adhering to all tried and tested methods to solve current problems and provide stability.

Installation: Comparing Django vs Ruby on Rails based on the installation process is not a difficult nut to crack. Django’s installation process is very simple and therefore it only takes about a minute to fully install.

But the same cannot be said about  Ruby on Rails. You must first understand what packages and gems are, as they are needed to install the packages for Ruby. These two are first installed and then run Command Gem Install Rails to finally install the latest version of the Rail’s framework

Security: In Django vs Rails comparison, we had to include the security factor as it is an indispensable part of any website or apps for that part.

Django has definitely got this feature from Python. In fact, NASA also uses Django frameworks, which in itself is enough fact that advocates how safe it is. Django is supported by medium goods while Rails is supported with active records. Django has tools that protect your Django app from SQL injection, cross-site scripting etc. and so does Rails.

Overall, both web development frameworks are a reliable alternative and can be trusted for security.

Scalability: Although the Django web framework has inherited scalability from Python, it is still a bit behind in comparison to Rails. It has better scalability which is the result of its attributes such as freedom and flexibility in code. They are both frameworks for heavy web developments, so they are both designed for scalability, but the Ruby on Rails development here takes the winning title.

Syntax: It is a known fact that Ruby’s syntax is very flexible. The benefits of Ruby on Rails may not always be associated. This can cause problems and make it more difficult to pass the project on to other team members as a feature can be achieved in many different ways and create confusion.

While Python advocates that there should be only one obvious way to do something, which makes the code easier to troubleshoot and read.

Principles of Development: Principles are like the glue that holds the entire development process together. Django has two prominent principles that are remarkable — DRY and “Explicit is better than Implicit”. This principle allows developers to create applications that are easy to understand and maintained by many people.

Ruby on Rails is also not short on development principles. It also uses DRY and Convention over Configuration, which advocates that in order to be productive, you must follow conventions instead of creating your own configurations. Doing so increases speed and efficiency.

Documentation of framework: To be simple, it is a link between Django vs Rails development framework in this regard. Both frameworks are well documented, making it easy to find the most popular FAQs and answers to the questions. The language in the documentation for both is very simple, understandable and simple, without putting the reader into the state of mayhem.

The maturity of the platform: Django was first introduced in 2005 and has since worked its way up the list of the best web development frameworks. Its latest version was released on April 2019 with many new features and better functionality.

Ruby on Rails was first introduced in 2003 but was officially declared an open-source framework in 2004. It is also regularly updated, as the latest version of it was launched in August 2018

HTML Templating: Although both Ruby on Rails & Django framework have the template as the main feature, Django uses a simple template language to allow developers to create templates with minimal programming and HTML skills. By contrast, Rails’ views (individual page templates) seem more complex.

Usage: If you are looking for a framework that helps develop complex websites based on databases and web applications in less time, with efficiency in systems administration, scientific programming, data analysis, and manipulation, then Django is the way to go.

On the other hand, Rails also helps develop database-backed web applications by providing better usability and freedom for programmers. Because Ruby is flexible in nature, it is an ideal choice for meta programming and the creation of pleasant codes.

Web Servers: For Django, the most important web servers are NGINX with WSGI, Apache, Gunicorn, and Cherokee. The database servers for Django are PostgreSQL, MySQL, SQLite, and Oracle.

While for Ruby on Rails, web frameworks use NGINX, Apache, and WEBrick as the prominent servers. Database servers for Rails include PostgreSQL and MySQL.

Community support and ecosystems: Django is an open-source framework and also has an open-source system, which means that there is a set of ​​libraries and tools, both paid and free, available to developers. Also, the official Django documentation is more than enough for reference if you need answers to any problem.

The Django community has over 11,000 people with more than 4,000 developers ready to use. Ruby on Rails, on the other hand, also has a very active community with 5,000 people dedicated to those who have already contributed a lot of Gems with reusable code

Learning To curve: It is widely known that Python is a very easy programming language to learn from its challenges, which also makes the learning curve for Django small. There are various resources available offline as well as online, which makes it easier to solve questions.

On the contrary, Rails has a very steep learning curve due to independent concepts, which a developer needs to hone in order to become proficient in Rails. So it is only recommended for experienced programmers and developers.

A closer look at Android Runtime: DVM vs ART

Before moving directly to ART (Android Runtime), we need to understand what the runtime environment is and also understand some basic things, that is, the functioning of JVM and Dalvik VM.

What is the runtime?

In a simpler term, it is a system used by the operating system that is responsible for converting the code you write in a high-level language such as Java to machine code and understands it by CPU / Processor

The runtime consists of software instructions that run when your program is running, even if they are not essentially part of the code for that particular piece of software.

CPU or a more general term, our computers only understand the machine language (binary codes), so in order for it to run on the CPU, the code must be converted to the machine code, which is performed by a translator

Next, the generation of the translator in a sequence is shown.

1. Assemblers: He directly translated assembly codes to machine codes, so it was very fast.

2. Compilers: Translate the code into assembly codes and then use assemblers to translate the code into binary. The use of this compilation was slow but the execution was fast. But the biggest problem with the compiler is that the resulting machine code depended on the platform. In other words, the code that runs on a machine may not run on a different machine.

3. Interpreters: Translate the code while executing it. As the translation occurs at runtime, the execution was slow.

How does the execution of the JAVA code work?

To maintain the independence of the code platform, JAVA developed JVM, that is, Java Virtual Machine. He developed JVM specific to each platform, which means that JVM depends on the platform. The Java compiler converts the .java files into .class files, which is called bytecode. This byte code is delivered to the JVM which converts it into machine code.

This is slower than C ++ compilation but faster than interpretation.

How does Android code execution work?

On Android, Java classes become a DEX bytecode. The DEX bytecode format is translated into native machine code through ART or Dalvik runtimes. Here the DEX bytecode is independent of the device architecture.

Dalvik is an engine based on JIT (Just in time) compilation. There were inconveniences to use Dalvik, therefore, since Android 4.4 (KitKat) ART was introduced as runtime and since Android 5.0 (Lollipop) it has completely replaced Dalvik. Android 7.0 adds a Just-In-Time (JIT) compiler with code profiles for Android Runtime (ART) that constantly improves the performance of Android applications as they run.

Read also : Android Application context

Key point: Dalvik used the JIT (Just in time) compilation while ART uses the AOT (Ahead of time) compilation.

Below is the code snippet that explains the difference between Dalvik Virtual Machine and Java Virtual Machine.

Just in time (JIT)

With the Dalvik JIT compiler, every time the application is run, it dynamically translates a part of the Dalvik bytecode into machine code. As execution progresses, more bytecode is compiled and cached. Since JIT compiles only part of the code, it has a smaller memory footprint and uses less physical space on the device

Ahead of Time (AOT)

ART is equipped with an Ahead-of-Time compiler. During the app installation phase, DEX bytecode is statically converted to machine code and stored in the device storage. This is a one-time event that occurs when an app is installed on a device. Because there is no need for JIT compilation, code execution is much faster.

Since ART executes the application machine code directly (native execution), it does not hit the CPU as much as compiling a just-in-time code with Dalvik. Battery consumption is reduced due to low CPU usage.

ART also uses the same DEX bytecode as input for Dalvik. An application compiled using ART requires additional time for compilation when an application is installed and occupies a slightly larger amount of space to store the compiled code.

Why does Android use the virtual machine?

Android uses a virtual machine as its runtime environment to run the APK files that constitute an Android application. The advantages are presented below:

• The application code is isolated from the central operating system. So even if some code contains some malicious code, it will not directly affect the system files. It makes the Android operating system more stable and reliable.
• It provides cross-compatibility or platform independence. It means that even if an application is compiled on a platform such as a PC, it can still be run on the mobile platform using the virtual machine.

ART benefits

•  Applications run faster since DEX bytecode translation is done during installation.
•  Reduces application startup time since native code is executed directly
•  Improves battery performance because it saves energy used to interpret byte codes line by line.
•  Improved garbage collector.
•  Enhanced developer tool.

Drawbacks of ART

• The installation of the application takes longer due to the conversion of DEX bytecode into machine code during installation.
• As the native machine code generated in the installation is stored in the internal storage, more internal storage is required.

Get a faster and more secure website: update your PHP today

Your WordPress site can be faster and more secure, and you can make it happen!

This Article explains why Update your PHP today, why PHP important to you and then how to fix it.

Why PHP is important to you

PHP is the coding language WordPress is built on and its version is set at the server level of your hosting company. Even if you know the importance of keeping WordPress and your themes and plugins up to date, it is equally important to keep PHP up to date.

There are two main benefits of keeping PHP up to date:

• Your website will be faster since the latest version of PHP is more efficient. The update to the latest compatible version (currently 7.3) can give a great boost to performance; up to 3 or 4 times faster for previous versions.
• Your website will be more secure. PHP, like WordPress, is maintained by its community. Since PHP is so popular, it is a target for hackers – but the latest version will have the latest security features. Older versions of PHP do not have this, so updating your WordPress site is important.

And then there are many secondary benefits:

• A faster WordPress site will be rewarded by search engines, so you will rank higher in the search!
• A faster site will retain visitors better (they will leave if it takes too long to load), making your site more efficient.
• A more secure site is better protected against hackers, and the cost and reputation damage associated with a hacked site

These benefits are good for you and good for website visitors. These are the reasons why you should update PHP today. The next part shows you how to do this.

Before updating your PHP version

This section starts with some warnings, but don’t be afraid! As with most technical things, we just need to cover some background before we can get to the part where you update your PHP version.

Updating your PHP version should not be a problem, but we cannot guarantee that it is not. WordPress itself works with PHP versions as far back as 5.6.20 (we currently recommend version 7.3, so it’s good backwards compatibility!), But we don’t know if your themes or plugins will work. They should be popular or reputable, but we can’t guarantee it.

There are a few steps you should take to reduce the risk before continuing:

Creating a Backup of Your Website: A backup lets you restore your site to what it is right now if something goes wrong. There are plenty of free backup plugins available, so if you don’t already have a backup solution – use one of these. To restore this backup, you also need your web host to move your PHP version back to your current version (we will describe how to do it later).

Update WordPress, Themes and Plugins: from your WordPress Dashboard, go to Updates and then update all. You should do this regularly anyway. When you’re done, make sure your website is working as expected.

Check PHP Compatibility: Install the PHP Compatibility Checker plugin to check your themes and plugins for any issues. This plugin is not perfect and can miss objects or flag false positives, but it works in most cases.

Fix any PHP compatibility issues: If the PHP Compatibility Checker plugin picks up any issues, contact the theme or plugin developer and ask them to investigate. If they can’t or won’t come back to you, look for themes or plugins on WordPress.org with similar features and use one of these instead

Run through these steps and you’re ready to update the PHP on your WordPress site – and enjoy all the benefits that come with it!

If you encounter problems when doing this or need help, you should contact a professional web developer, your web host, or your author of theme and plugins. All of these are happy to help here. We can now move on to the last part: actually update your site’s PHP version.

How to update your website PHP version for a faster and more secure site

You are now ready to update your site’s PHP version! You have done due diligence, received backups and are in the best possible shape to do the update.

Because the PHP version is set at the server level of your hosting company, updating either means interacting with the host’s settings or asking them to do so.
So exactly how you do the update depends on your hosting company. We have asked hosting companies to submit instructions on how to update your PHP version to their host, and you will find a list of hosts that have instructions available here.

If you encounter any problems at this stage, change either the PHP version yourself, contact your web hosting company or a professional web developer. In the unlikely event, something goes wrong and you need to restore your backup, contact your host and ask them to restore an earlier version of PHP you had run. You can then restore your backup.

Now you should have all the information you need to update! Good work! With an up-to-date version of PHP, you will enjoy a faster, safer site and happier visitors

Faster, more secure WordPress sites for everyone

Ensuring that you have the latest version of PHP ensures that your site is as fast and secure as possible.

Now you have all the information you need to update to the latest version of PHP, and you know how to update in the future as well. Want to know more about PHP update then PHP training in Chandigarh is the best option for you. 

5 Simple Web-Design Tips to Boost Conversions

Attracting online shoppers can be complicated. While your website may seem professional and include social evidence and trustworthiness, you might overlook less obvious design elements that can affect conversions. But do not worry; You don’t have to be a web designer to understand and implement these 5 simple Web-Design Tips to Boost Conversions.

Few Web-Design Tips to Boost Conversions

Related Post: 5 Tips for Creating an Effective Website for Your Business

1. Choose the correct colors.

When choosing colors for your website, you should not simply choose your favorite. Instead, you should consider the emotions that each color will convey and if that emotion matches your brand. It is commonly believed that certain colors affect the way we feel about a business, even if we decide to make a purchase.

It is believed that the color blue, for example, evokes feelings of trust, strength, and reliability, which is why companies like Dell, Ford, and American Express use it. On the other hand, companies like Lego, Nintendo, and YouTube chose red because it tends to evoke excitement and youthfulness.

Therefore, consider the colors of your website to convey to your audience. Do you sell healthy lifestyle products? Then think about choosing green to evoke peace and growth. And also keep in mind that using high contrast colors helps highlight the most important elements, such as call-to-action buttons.

2. Consider the typography.

Just as colors cause-specific emotions in people, so do fonts, so you should choose the typography for your website that represents your brand accurately. For example, if your company makes handmade furniture, you might consider choosing a font that tells your audience that reliability and comfort are important to you.

In addition, creating enough space between lines of text will make your content easier for users to read. The magic line height (the space above and below the text lines) is 150 percent of the font size you are using.

3. Use the negative space.

Negative space refers to the space between all the different elements of your website, such as the one between the header and the content. A lot of negative space on your website is really a good thing since it allows you to concentrate on the most important elements, such as a striking main image and a call to action, and general readability.

4. Choose an F pattern.

Pattern F refers to the way our eyes move when we read online content. Usually, people scan from left to right at the top of the screen, then their moving eyes scan down the page, scan to the right again, but less than at the top of the screen. Then, the area of ​​the page that gets the least visibility is the lower right corner. This eye movement finally resembles a form of “F” or “E”. When implementing your F-Pattern, place your most important elements and your calls to action in the areas that will be most visible. For example, if you place your call to action on the top left of your website page, you will stand out among your visitors and get more clicks.

When designing your company’s website, you cannot think about what your company wants or needs. On the contrary, you should think about what is best for your visitors. Use these simple design tips to improve the way users consume the information they need most, and an increase in conversions is sure to follow.

5. Unique Selling Point

The unique selling point of your website differentiates you from the huge pool of websites that exist. To get the attention of the user, your web design must have a unique design that separates it from the crowd. However, in addition to getting the user’s attention, make sure that your USP also stays in the user’s mind.

6. Respect Users’ Patience

Or rather, impatience. It turns out that people are incredibly impatient, especially when it comes to surfing the web, a one-second delay in page load time results in a 7% reduction in conversions!

In terms of web design principles, this means that you must verify the speed of your page and solve any problem, run your site through one or more of these free tools:

• Google PageSpeed ​​Insights
• Pingdom
• GTmetrix
• KeyCDN

Now you know how your web design can boost the conversion of your website. Simply implement the above principles and Simple Web-Design Tips to Boost Conversions. You will see more visitors and surprisingly more conversion rate.

5 tips to create an effective website for your business

If you are running a small business and feel it is time to expand and reach a clientele beyond the small town you had attended, you should start by creating a website. You can set it up yourself or go to a web design services provider company in Chandigarh. It is important to know that the website is not only a piece of decoration, but that it is partially responsible for managing your business and should make it work.

But how do you make sure it works? The website has two main functions: the first is to attract and involve consumers and the second is to encourage them to become customers. Customers could enter your store or better yet, they could simply offer you business on your website. To perform its functions effectively, you must ensure that your website is equipped with some basic features. Must be able to make the visitor spend time exploring the website; If you do not, it is time to rework your website to  make it effective.

It must look attractive

The first impression of a website is permanent. If it doesn’t impress a visitor for the first time, you may never get it to be your customer. Work on the website to make it look welcoming and attractive. It doesn’t have to have nice images to make it attractive; in fact it can really distract you. It is important that it appeals to your customers. Therefore it must contain elements that the customer can relate to.

Avoid adding too many elements, but enter enough to communicate your message. Clutter can cause your message to be lost, but for some industries that might be a good idea. So you do not have to generalize, but adapt it to your needs. This transformation does not have to cost you much. If you wish, you can use the various free themes available  online. 

Provide easy access to contact information

The website must prominently display your full contact information. You could have it on the home page or you can have a separate page with detailed contact information, complete with the physical address, email address, telephone numbers and links to various social media platforms where you are present. 

If you do not like to take random calls, you can add a contact form where they can fill in all the details so that you can contact them. Another option is to have a live chat session on your website. The customers can immediately remove the doubts by chatting with the employee or chatbot

Show off your happy customers

Nothing is more convincing than a satisfied customer and you have to take full advantage of this. Encourage your customers to leave reviews and ratings on the website. This works well when new visitors see them. Impressed by the positive feedback from other customers, they also feel encouraged to add their name to your customer list.

You can also present your customers on a separate page by prominently displaying the logos of your valued customers, awards received and media attention. You can talk about some of your successful projects that show off your best work

Share information via a blog

A blog can be interesting to read if a variety of information is available to your customers. It keeps the visitors involved. For this it is important that your message is creative, informative and entertaining – all at the same time. Share information about events and developments in your field, along with interesting tips on how they can make full use of your services. These also ensure that you are established as an expert in your field.

Encourage action from your consumers

Of course you cannot simply tell your customers that they should do business with you, so you must work strategically to make them take a small step forward. You can ask them to like your presence on social media. They can subscribe to your newsletter or maybe contact you if they are not yet ready to become a customer

If they are ready for business, you are and you must offer them the best service. You can then encourage them to leave a review for the benefit of other consumers like them.

With the website in place with just the right elements, you should expect some growth in your business, but you will also need to use some SEO activities that can be planned by your web designing training in Chandigarh. An old website can cause the consumer to lose interest and all your efforts to be lost. That is why you must continue to update the content on your website. You must not forget that maintaining the website is just as important as designing it.
