Introduction

It is a well-established fact now that for any company to flourish it needs to have its presence on the digital platform. While social media can be the right place to attract some attention but it does not establish a brand image of that company without a proper website. As a result of this businesses are hiring the best web development company to ensure that they get the website designed that would allow them to get as much traction as possible.

There are several technologies that are available in the market for developing a website but most of the developers use PHP as the technology for website development. This has resulted in a significant rise in PHP development companies. There are several reasons that PHP is the choice of web developers for creating a website.

In this article we will look into the role of PHP in web development and why developers at any custom software development company prefer to use PHP for developing a webpage.

Role Of PHP in Web Development

As mentioned earlier PHP is a server-side scripting language, which means the client only receives the output since the processing happens in the server. The processing is done by using the resources of the server before sending the output. This is in contrast to languages like JavaScript in, which the language is processed on the computer of the client and the resources used are from the computer and not a server.

Normal vs. PHP Web Request Cycle

The cycle of Normal Web: When a client requests for an HTML page then the process happens in the following format:

– Client requests
– A request for ‘welcome.html’ is done, i.e locate the welcome.html and send it as the response to the server.
– From there the response for ‘welcome.html’ arrives
– Which then goes to the client

The cycle of PHP Web Request: When client requests for a PHP page then the process happens in the following format:

– Client requests
– A request for ‘welcome.php’ is done, i.e. a request is sent to the PHP engine. A response is sent as an output from the server.
– The response for ‘welcome.php’ is then sent to the client.

Dynamic Content

When you enter welcome.html the code is different from that of ‘welcome.php’. To explain it further, depending on the time of the day when you request ‘welcome.html’ you will always receive the response ‘Welcome!’ as the heading. Whereas, when you request welcome.php depending on the time of the day you will receive ‘Good Morning’ if it is before 12 pm and ‘Welcome!’ after 12 pm.

This indicates that welcome .html has a static behavior compared to welcome.php, which is dynamic. It is because welcome.html always delivers the same content, whereas PHP changes are as per the time. This allows you as a developer to improve on files thus making it more dynamic than HTML.

PHP Engine Output

PHP engine outputs contents differently from that of HTML, the reason being PHP interpreter reads the lines of the file that are tagged between and then processes that. Any content without the PHP tag will not be processed by the PHP engine.

If as a client you want PHP to be embedded in HTML that is also possible, only you have to hire PHP developer who is proficient in such a task and knows how to do it.

Why PHP Is The Choice For Web Developers?

There are several factors apart from the fact that PHP is dynamic that has resulted in best web development companies preferring to use PHP for developing websites. Here are some of the reasons:

• Easy to learn: Compared to other languages like Java and C, PHP is much easier to learn and easy to use too.

• Open Source and Free: The components of the language are free to use since it is an open source. So all you have to do is contact PHP development company and your job can be done easily and in a cost-effective manner.

• Cross-Platform: PHP can run on all the major OS like Mac OSX, Windows, and Linux thus saving lots of time for developers.

• Easy to Deploy: Deploying a PHP is easy and at a low cost since many hosting companies willing to offer a server for running the website.

• Less Time to market: One of the factors that many custom software development companies prefer to use PHP for web development is because of its less time to market feature. This will allow any enterprise to gain better popularity than the competitor.

• Reliable: Depending on how the developer codes, the web language can turn out to quite efficient. It is also scalable when the codes are written, thus making it a reliable language.

• Faster Processing: Since PHP uses its own memory space, it automatically reduces the loading time and server workload. Thus giving it better and faster processing capacity. Hence it is effective for websites that have high traffic.

• Built-in function: Many useful tasks like sending emails, generating GIPFs, PDF documents and connecting to other network servers can be done with PHP since it has its own libraries.

• Secured: This is one language that has one of the best layers of security protection in the market. Hence developing a website or app with PHP is much more secure than any other language.

• User-friendly: The simplicity of any website or app created with PHP makes it user-friendly since it is easy to understand and use.

• Tested and Proven: Over millions of people have been using websites created with PHP for over two decades. It’s abilities and functions have been tested time and again and have proven to stand the test of time.

• Extensions: The extensions in PHP allow modifying the source code file and managing them too making it the most used language by the developers.

• Flexible: The functionalities of a website or an app might need changing several times when it is being developed or later too, PHP allows a seamless way to do that without any hassle.

• Easy to Integrate: With PHP you do not have to re-code and re-develop as it can easily integrate with the current company software.

• Supportive community: PHP has a large community of developers who keeps updating the forums with news and benefits. It is a reliable source of information on PHP and other related issues. So if you ever get stuck the PHP community is there to support you.

Conclusion

PHP offers the option of running on a web server since it is a server-side scripting language. It is also secure, reliable and fast that has resulted in web developers preferring to work with PHP. So it would quite beneficial for any enterprise to hire a PHP developer than a general web developer.

A PHP developer who specializes in this language knows the dynamic nature of the scripting language that can enhance the appearance and function of the website. Irrespective of the industry that the web page belongs to, a web page created with PHP is more dynamic and also easy to use.

Software development is more important than ever.

Millions of businesses around the world are finding it more and more necessary to improve the quality of their apps and attract users.

However, despite the growing importance of software development across nearly every industry, far too few entrepreneurs know about the importance of simplicity when it comes to sleek software development.

Here’s why simplicity in software development should be a mantra you closely follow, and how to supercharge the process of creating your next app.

Users want simple software

The first tenet of good software development is that everything must ultimately produce a smoother and more enjoyable experience for the user. This is crucially important to remember, as most users want good software, meaning you need to streamline your app if you want it to be a hit.

Unless you take specific steps to ensure that the software you’re developing is simple enough that the average user can effectively wrap their head around it, your entire investment will be effectively squandered. Nevertheless, simplicity in software engineering is never simple and frequently expensive, so knowing how to go about producing stellar software that’s still simple is important.

The acronym “KISS” once surfaced in the U.S. Navy as a way to remind those developing warships to keep their designs simple; after all, if things got too complex then the engineers wouldn’t be able to make repairs in the midst of combat.

Similarly, you should be taking steps to embrace the principle of KISS in software design and development, as your IT specialists must be able to grapple with your software under tight deadlines successfully. For that, it must be simple and streamlined.

Those two reasons are the most important elements of why simplicity in software development should be a mantra; if consumers demand it and engineers need it, software must include it. Another problem you’ll encounter in software development is that users don’t want to read your manuals, and having a simple product is a surefire way to make them read the manual in a more effective fashion. Elsewhere, you’ll also want to streamline the software development process in order to cut down on the long-term costs of doing business.

Simple software is cheaper

Simple software development isn’t just cheaper to initially produce, but it’s also substantially cheaper and easier to maintain in the long run. In this day and age, buying software in and of itself means next to nothing – you’re oftentimes buying the expertise needed to keep that software updated and attractive to users for at least a few months. Making sure that your software development is guided by a principle of simplicity is thus a good way to ensure that future maintenance costs don’t spiral out of control thanks to a complex program that requires many experts to update.

Making sure that your software development is as simple as possible is also a good way to guarantee that your product is ultimately devoid of dead code. Any developer can tell you a nightmare about how dead code stymied the ability of their product to meet the needs of users, so don’t make the mistake of churning out some complicated product with so many bells and whistles that half of them end up becoming obsolete.

The risks of dead code can’t be underrated, so understand that simplicity as a mantra in software development will help you ensure that your investment pays off in the long run without ageing into obsolescence.

Above all else, simplicity must be a mantra in software development because it makes things easier for your team of developers, your workers using the product, and the users who may end up relying on that software, too. The more you streamline the app development process, the more time your developers will have to focus on the meeting the basic principles and goals of your project.

Similarly, a simple software can be easily mastered by employees, helping you cut down on the expensive costs of training that quickly rise up when complicated software is being used.

Ensure that simplicity is your guiding mantra when it comes to software development, and you’ll soon see better results than ever before.

Choosing between PHP and ASP.NET for web development is a tough task, specifically so because one is simply a programming language and the other is a web framework.

As both PHP and ASP.NET are popular technologies and highly preferred by development for web application development, it becomes extremely to choose between one.

So, we decided to create PHP vs ASP.NET comparison guide to help beginners and business owners from non-technical background to pick the one for their web application development project.

PHP Vs ASP.NET: An Overview

The Essentials Of PHP Architect

Hypertext Preprocessor abbreviated as PHP is known popularly as an open source scripting language. Used generally for web development, PHP is easy to embed with HTML. PHP is popular for a number of reasons and one of the best is the framework offers easy coding techniques, a reason enough for beginners to have a soft corner for this programming language.

A Brief On ASP.NET

Developed by Microsoft, ASP.NET is a server- side web development tool. The web application development framework helps develop dynamic web pages, which is one of the reasons for its popularity. Being a Windows-based platform, ASP.NET offers multiple environment and development modes. It thus becomes easier for beginners also to create APIs and build web forms.

PHP Vs. ASP.NET: The Comprehensive Comparison

Comparison On Speed And Performance

Before we talk about the speed and the performance, let me acknowledge you with some facts that are equally essential for determining a website’s speed. PHP and APS.NET websites differ just a bit in regards to the performance. Here is an example to illustrate how a website’s speed is measured.

Let’s start it with a basic example. The primary task of any website is to output the result of a query database in order to show the results ultimately to the user’s browser.

So, the scenario here is, there is simple communication between the database and the web server to produce the output.

In the case of PHP and ASP.NET, both are equally equipped to access files, and find images. The speed of all these performances depend much on the database server, end user’s system, and bandwidth, etc.

Many beginners may not be aware that the speed of ASP.NET websites is comparatively better than that of PHP. More to this, ASP.NET allows parallel programming to support coding structure that run all the time. In the case of PHP, it doesn’t allow threading at all.

Small Business WebsitesEnterprise Level Websites
Billing/Invoicing WebsitesIntranet
StartupsERP Apps

Comparison On Popularity

In terms of popularity, PHP does have a higher graph than its competitor. There are a few reasons that offer PHP more popularity than its counterpart. Statistics show that PHP has 67% of the share while ASP.NET’s percentage is less than 50%.

That being said it’s nothing like ASP.NET is not favored by developers today. The language is growing exceptionally well among the developers. This comparison here is worth an example to illustrate the ongoing popularity of this framework.

Comparison On Scalability

On the radar of scalability, both PHP and ASP.NET are incredibly scalable. However, while choosing the preferred language, it is far better to consider the state of the business to choose the right platform.

PHP is suited to the websites having Drupal in their core. The fact that PHP comes with the lowest learning curve makes it the best for such a development.

Moreover, the scalability quotient of PHP and ASP.NET is quite high. As a matter of fact the world’s most traffic-rich websites like Facebook and Wikipedia, use PHP. While websites like Microsoft and StackOverflow use ASP.NET.

Comparison On Cost

This area is probably the one where PHP has a distinct advantage over ASP.NET. The reason behind this benefit is PHP is open source while ASP.NET is owned by Microsoft that charges a minimal web hosting fee.

Worth noting, PHP can be used on Linux, Mac, and Windows systems while ASP.NET services are only meant to be used on Windows machine.

However, there is a minimal cost but developers don’t mind paying the same to use the programming language for website development.

PHP vs ASP.NET: An Extended Comparison Chart

Kotlin, a language first released eight years ago to provide an interoperative platform with Javascript in a neater package was added to Android Studio IDE just two years ago, and after a close-run battle with Apple’s Swift, it has become a firm favourite with developers.

Although Java has long been the preferred language for Android apps, the news isn’t a complete surprise, given Google’s long-running legal dispute with Java’s patron, Oracle.

According to TechCrunch, delegates were told: “We’re announcing that the next big step that we’re taking is that we’re going Kotlin-first,”

Chet Haase, chief advocate for Android, added: “We understand that not everybody is on Kotlin right now, but we believe that you should get there,” Haase said. “There may be valid reasons for you to still be using the C++ and Java programming languages and that’s totally fine. These are not going away.”

Explaining what that means in real terms, Google’s written announcement explains: “Many new Jetpack APIs and features will be offered first in Kotlin. If you’re starting a new project, you should write it in Kotlin; code written in Kotlin often mean much less code for you-less code to type, test, and maintain.”

The ‘Jetpack’ in question is Jetpack Compose, a new open source UI toolkit for Kotlin, which uses a reactive programming model, akin to React Native or Vue.js.

There are different components and plugins available for everything from Android Auto to Wear OS and all points in-between. There’s CameraX, which is specifically aimed at camera related developments – which could also come in useful for augmented reality (AR) projects. There’s also a range of security-focused plug-ins for enterprise development.

Kotlin now sits at number 4 in Stack Overflow’s list of programming languages preferred by developers, and powers development in over half of actively developed Android apps (says Google).

Microsoft has moved to clear up the confusion sparked by its reveal of the Windows Terminal application for Windows 10.

Since the announcement, Microsoft program manager Kayla Cinnamon says the company has been repeatedly asked whether the new terminal app for command-line programs will replace Windows Command Prompt or Microsoft’s PowerShell command-line shell.

Cinnamon clarifies that the Windows Terminal provides a text terminal for connecting to system shells such as PowerShell and Command Prompt. As such, Windows Terminal isn’t a replacement for either shell, but a tool designed to be used with them.

The Windows Terminal is being built to offer many advantages over the existing Windows Console when connecting to system shells.

Windows Terminal will support multiple tabs and be able to connect to a wide range of shells, including Command Prompt, PowerShell Core, Ubuntu, openSUSE, Debian, a Raspberry Pi via SSH, and more.

It will also be highly customizable, with support for background transparency and blur, different colors, themes and styles, mousewheel zoom, and a plethora of keyboard shortcuts.

Its advantages over Windows Console have led Microsoft to also be asked whether PowerShell will replace Windows Console.

Again, Microsoft’s Cinnamon says the answer is ‘no’.

“Windows Console will continue to ship within Windows for decades to come in order to ensure backward compatibility with the many millions of existing/legacy command-line scripts, apps, and tools,” she writes in a blog post, adding Windows Console will run alongside Windows Terminal.

Developers can try out Windows Terminal by building the application from source code available via GitHub.

However, Microsoft has said the application is currently in a very early alpha stage, with many features still to be added.

Microsoft will release Windows Terminal as a Microsoft Store app, and is aiming to release a preview version of Windows Terminal by Summer 2019 and a full version by Winter 2019.

In other developer news, Microsoft made a series of announcements to coincide with the KubeCon event taking place in Barcelona. KubeCon centers around Kubernetes, the open-source software for deploying and managing containers.

Microsoft revealed the alpha release of Helm 3 package manager for Kubernetes, the 1.0 release of the Kubernetes extension for the VS Code editor, the 1.0 release of the Virtual Kubelet project for simplifying the process of using Kubernetes with public cloud services such as Azure Container Instances, and the launch of the Service Mesh Interface, which defines a set of common APIs that offer interoperability across different mesh service technologies.

Software development is a crucial process in any organization. It is because the software is the core of every business and helps the organization put other resources in use effectively. Thus, organizations are very peculiar about the software development project and ensure that there are no stones unturned in order to get quality output in speculated time.

However, there is a time when the planning goes wrong and software is not developed as decided in the first place. If facts are to be believed there are around 70% software development projects failure across the globe. Hence, organizations make sure to take all necessary steps before getting started with actual software development. They need to be sure of specifics, details, and the designing of the software development project.

However, there is a time when the planning goes wrong and software is not developed as decided in the first place. If facts are to be believed there are around 70% software development projects failure across the globe. Hence, organizations make sure to take all necessary steps before getting started with actual software development. They need to be sure of specifics, details, and the designing of the software development project.

Questions to Ask to Your Software Development Company Before Starting the Development Project
Hence, enterprises need to ask 7 basic questions to software development companies if they are planning to get it outsourced so as to ensure that they are on the right path and the project would come out as detail-oriented as possible. What are those questions? Let’s check it out.

  1. What is the Development Process that’s Followed?
    Every software or custom app development company has a development process that they follow which starts from planning and ends to delivery and maintenance. While this is the usual protocol being followed, there might be some other overall process that the company follows. You need to be sure of their development process to realize and understand their effectiveness of software development. Few things you can highlight are:

a) Team of software developers
b) Internal communication amongst team
c) Team experience
d) Dedicated team for different sections and more

  1. What would be the List of Actual Deliverables?
    An entire software development project consists of many differentiated deliverables like website, design, program, codes, and etc. Each has its own importance and is somehow interrelated that once combines uplifts the use of a software project. An enterprise needs to discuss with software development company about the deliverables. Expecting more could add the costing and thus business need to be sure of the deliverables that they actually require to function and operate the business easily.
  2. What Elements would be Non-Deliverable?
    Like discussing the deliverable elements, enterprises also need to discuss the elements that are not required and can be marked as non-deliverables. This is an important question and points to be discussed as the project itself is an amalgamation of multiple elements and not every time all the elements are required by the business. So, while you have discussed and decided your requirements and deliverables with the team, it’s also necessary to jot down elements that are not required. This saves the time of software development company who are taking your project and yours as well.
  3. What is the Deadline?
    Another question that needs to be discussed between both the parties is the deadline. Both business and software development company need to be transparent about the delivery deadline. This pushes the team to finish the work in stipulated time and the business to act and plan the launch of the project accordingly. Any miss or delay in delivering the project need to be clearly communicated well in time so that backend plan can be incorporated.
  4. Is Team Technology Familiar?
    Before handing over the project to the software development company, another important question to ask is if the team going to handle your project is technology familiar or not. It’s essentially required if the business wants the project to be curated and developed using a specific technology only. If the developers are not familiar with the technology or have basic knowledge and experience of the same, then the business should step back and search for the right partner to collaborate with.
  5. What Quality Process do Development Company Follow?
    There is no use of assigning your project to the development company if they don’t follow any protocol to assure and measure quality. The quality check ensures that the project is tested internally, good to perform and ready to launch to end users. Quality testing can be achieved through:

a) Unit testing
b) Manual testing
c) End to end testing
d) Integration testing

  1. What is the Deployment & Maintenance Strategy?
    Last but not least, software development project all comes down to its deployment and maintenance post-project delivery. The business should make it clear from the development company if they will be supporting them with deploying the software in their system and assuring maintenance once the project is delivered. This is an essential part not to be missed as it decides the future of the project performing exceptionally in the business system.

Conclusion

Wrapping up, software development or custom app development is the requirement of every business today. Without technological advancement in business, there is no future of business. And this push businesses to rely on software development company to amalgamate their internal process with software for automotive operations. Before finalizing the software development team, the business should do a background check and measure the company so that it fulfills the organizational need for business growth.

Java developers and the blockchain, is it a match? Java programmers interested in developing smart contracts have a new tool on the horizon.

The BloxBean project launched Aion4j, a set of dev tools and frameworks for building smart contracts on the Aion Virtual Machine. Currently in its conceptual stage, it presents several goals on its roadmap. Let’s take a look at its proposed goals, what it includes, and what potential problems it solves.

Proposed goals

According to the GitHub repo, the following lists the proposed goals for Aion4j’s lifespan:

  • A set of developer tools and frameworks to help smart contract development on the Aion Platform. The idea is to leverage on the existing tools (IDE, Frameworks etc.) in the Java ecosystem.
  • Abstract all the complexities of blockchain interaction from a Java application and provide a POJO / Interface based programming model.
  • Enable Java developers with familiar tools to iterate faster during development with a relatively smaller learning curve. (Through an embedded FastVM runtime and libraries)
  • Help developers to develop with their existing Java development tools.

These goals aim to make it easier for mainstream Java developers learning how to develop smart contracts by using skills and language knowledge they already have. It introduces concepts and provides the necessary development tools for a streamlined, productive process.

By the latest Oracle estimate, Java runs on 3 billion devices and the TIOBE index lists it as the number one most used programming language. This shows that Java knowledge is common, and tools for making Java blockchains easier may lower the bar necessary for entry.

The Aion Foundation release announcement also notes that: “By supporting Java, AVM has already opened the possibilities of using established development tools in the Java ecosystem instead of re-inventing the wheel.

Read more about the Aion VM in their docs here. It runs Java bytecode on the blockchain.

Maven plugin

The Aion4j Maven plugin for AVM provides end to end tooling support for building smart contracts.

According to the Aion network’s launch announcement, key features found in this plug-in include:

  • Maven-based AVM project creation
  • Compile & package
  • Unit test
  • Deploy, test, and debug on embedded AVM or Nodesmith during development
  • Test and deploy on remote Aion Kernel
  • Use Maven commands to interact with the Aion blockchain
  • Client side transaction signing

Find the GitHub repo here. Follow and keep up with the in-progress goals.

IDEA/IntelliJ Plugin

Aion4j provides a plugin for smart contract support inside the IntelliJ IDE.

This provides an embedded AVM execution environment inside of the IDE. Users can test and deploy their smart contracts inside of the IDE during development. The IntelliJ plugin contains features that developers will need to write their smart contracts, so that they will not need to go outside of the IDE during development.

Because of this, no other software is necessary for writing and testing smart contracts.

In my previous  article, I  talked about model governance and holistic model management. I received great response, along with some questions about the differences between Data Science and Software Development  workflow. As a response, this piece highlights the key differences in processes, tools and behavior between Data Science and software engineering teams, as well as best practices we’ve learned from years of serving successful model driven enterprises. 

Why Understanding the Key Differences Between Data Science  and Software Development Matters

As Data Science  becomes a critical value driver for organizations of all sizes, business leaders who depend on both Data Science  and Software Development teams need to know how the two differ and how they should work together. Although there are lots of similarities across Software Development  and Data Science , they also have three main differences: processes, tooling and behavior. In practice, IT teams are typically responsible for enabling Data Science team with infrastructure and tools. Because Data Science  looks similar to Software Development (they both involve writing code, right?), many IT leaders with the best intentions approach this problem with misguided assumptions, and ultimately undermine the Data Science teams they are trying to support.

Data Science  != Software Engineering

I. Process

Software engineering has well established methodologies for tracking progress such as agile points and burndown charts. Thus, managers can predict and control the process by using clearly defined metrics. Data Science  is different as research is more exploratory in nature. Data Science projects have goals such as building a model that predicts something, but like a research process, the desired end state isn’t known up front. This means Data Science  projects do not progress linearly through a lifecycle. There isn’t an agreed upon lifecycle definition for Data Science work and each organization uses its own. It would be hard for a research lab to predict the timing of a breakthrough drug discovery. In the same way, the inherent uncertainty of research makes it hard to track progress and predict the completion of Data Science  projects.

The second unique aspect of Data Science  work process is the concept of hit rate, which is the percentage of models actually being deployed and used by the business. Models created by Data Scientists are similar to leads in a sales funnel in the sense that only a portion of them will materialize. A team with 100 percent reliability is probably being too conservative and not taking on enough audacious projects. Alternatively, an unreliable team will rarely have meaningful impact from their projects. Even when a model didn’t get used by the business, it doesn’t mean it’s a waste of work or the model is bad. Like a good research team, Data Science  teams learn from their mistakes and document insights in searchable knowledge management systems. This is very different from Software Development where the intention is to put all the development to use in specific projects.

The third key difference in the model development process is the level of integration with other parts of the organization. Engineering is usually able to operate somewhat independently from other parts of the business. Engineering’s priorities are certainly aligned with other departments, but they generally don’t need to interact with marketing, finance or HR on adaily basis. In fact, the entire discipline of product management exists to help facilitate these conversations and translate needs and requirements. In contrast, a Data Science  team is most effective when it works closely with the business units who will use their models or analyses. Thus, Data Science team needs to organize themselves effectively to enable seamless, frequent cross-organization communication to iterate on model effectiveness. For example, to help business stakeholders collaborate on in-flight Data Science projects, it’s critical that Data Scientists have easy ways of sharing results with business users.

II. Tools and Infrastructure

There is a tremendous amount of innovation in the Data Science  open source ecosystem, including vibrant communities around R and Python, commercial packages like H2O and SAS, and rapidly advancing deep learning tools like TensorFlow that leverage powerful GPUs. Data Scientists should be able to easily test new packages and techniques, without IT bottlenecks or risking destabilizing the systems that their colleagues rely on. They need easy access to different languages so they can choose the right tool for the job. And they shouldn’t have to use different environments or silos when they switch languages. Although it is preferable to allow greater tool flexibility at the experimentation stage, once the project goes into deployment stage, higher technical validation bars and joint efforts with IT become key to success.  

On the infrastructure front, Data Scientists should be able to access large machines, specialized hardware for running experiments or doing exploratory analysis. They need to be able to easily use burst/elastic compute on demand, with minimal DevOps help. The infrastructure demands of Data Science  teams are also very different from those of engineering teams. For a data scientist, memory and CPU can be a bottleneck on their progress because much of their work involves computationally intensive experiments. For example, it can take 30 minutes to write code for an experiment that would take 8 hours to run on a laptop. Furthermore, compute capacity needs aren’t constant over the course of a Data Science  project, 

 with burst compute consumption being the norm rather than the exception. Many Data Science techniques utilize large machines by parallelizing work across cores or loading more data into the memory.

III. Behavior   

With software, there is a notion of a correct answer and prescribed functionality, which means it’s possible to write tests that verify the intended behavior. This doesn’t hold for Data Science  work, because there is no “right” answer, only better or worse ones. Oftentimes, we’ll hear Data Scientists discuss how they are responsible for building a model as a product or making a slew of models that build on each other that impact business strategy. Unlike statistical models which assume that the distribution of data will remain the same, the distribution of data in machine learning are probabilistic, not deterministic. As a result, they drift and need constant feedback from end users. Data Science  managers often act as a bridge to the business lines and are focused on the quality and pace of the output. Evaluating the model and detecting distribution drift enables people to identify when to retrain the model. Rather than writing unit tests like software engineers, Data Scientists inspect outputs, then obtain feedback from business stakeholders to gauge the performance of their models. Effective models need to be constantly retrained to stay relevant as opposed to a “set it and forget it” workflow. 

Final Thoughts

In general, there are several good practices for Data Scientists to learn from Software Development , but there are also some key differences to keep top of mind. The rigor and discipline that modern Software Development  has created is great and should be emulated where appropriate, but we must also realize that what Data Scientists build is fundamentally different from software engineers. Software Development and Data Science processes often intersect as software captures much of the data used by Data Scientists as well as serving as the “delivery vehicle” for many models. So the two disciplines, while distinct, should work alongside each other to ultimately drive business value. Understanding the fundamental nature of Data Science  work can set a solid foundation for companies to build value-added Data Science  teams with the support of senior leadership and IT team.

Every job needs an appropriate tool for the kind of role that it has. The programming language skill depends very much on the job role. But there are some programming languages that have a demand in a majority of job roles and also have a high pay for it.

Here is a list of top 8 programming languages that will help you earn more in 2019:

1. Python:

Python is the most popular and demanding language in the job market. According to a survey by Analytics India Magazine, in 2018, 48% of respondents said that Python was the most important language to be learnt by a Data Scientist. In 2019, this sentiment is being clamoured, as almost 75% of the respondents are talking about the importance of Python in data science. The language which is scripted as opposed to compiled will continue to have the demand that it has today in the future. It is easy to learn and has an easy to understand syntax and official tutorials for beginners. It is free, open-sourced and has an easy integration with the web services. It is especially popular in data science and machine learning and also has a GUI-based desktop application.

Python users:  YouTube, Instagram, Pinterest, SurveyMonkey are all built in Python. World of Tanks, Inkscape, Civilization IV, Sims 4, Vegas Trike and Toontown are some of the video games for which Python has been used. It is also used for scientific and computational applications such as FreeCAD and Abacus. Many startups use Python as their primary backend stack.

2. Java

Java, owned by Oracle Corporation, is the second most popular choice in large organisations and it has remained so for decades. It is used by a number of large organisations and is very widely used in Android App Development. Presently, there are more than 3 billion devices that are running applications that are built with the help of the language. Java is widely used for building enterprise-scale web applications, something that every organisation requires. Its policy of Write Once Run Anywhere (WORA) lets it be flexible to run on any platform and be portable across a wide range of platforms from mainframe data centers to smartphones. Java frameworks of Spring, Struts, and Hibernate are very popular.

Java users: Java is mostly used as a backend language in a number of websites like Amazon, Google, Twitter and YouTube. If you are looking for a development based job at a large organization deploys Java at large.

3. JavaScript:

The object oriented language is most popular for interactive effects within the browsers. It is most popularly used to design interactive frontend applications. According to GitHub, it is the most popular language. It is a frontend language and is used in a number of popular web frameworks such as AngularJS, Node.js as well as React.js. It has a rich interfaces versatility and a single programming language for server side and client side scripts can be used with this language. Typescript is considered as a superset of JavaScript and it adds optional static typing features to the language software.

JavaScript users: Many startups are using NodeJS which is a JavaScript-based run-time environment. Majority of websites today use JS as their frontend, some popular examples of which are YouTube, Facebook, Google, Wikipedia and Amazon.

4. Swift:

Developed by Apple in 2014, is the most popular language for mobile platforms and was originally intended to be the replacement to C-based languages. It supports almost everything that is ranging from the programming language to the Objective-C. It was developed for usage in Linux and Mac applications. It is mainly used to keep the mobile apps in iOS-based devices as modern as possible. It mostly works towards safety performance and software design patterns. It helps the developer mistakes to be caught before the software goes into production. It also has a clean syntax and can be easily used with the IBM Swift Sandbox and the IBM Bluemix.

Swift users: App studios such as KeepSafe and Solstice need Swift coders. It is used in a number of iOS apps such as Mozilla Firefox, WordPress, SoundCloud and Flappy Bird game. Both Lyft and IBM use Swift instead of Objective-C. Those who want to serve the Apple community should learn Swift.

5. PHP

PHP programmers can embed the code written in server-side programming language flawlessly into HTML code throughout the Script tag. It plays a key role in web programming and server side scripting. It is equipped with a number of tools making it more efficient. These tools are used in the development by adding useful features and functionalities to the web application and carry on web development tasks without writing prolonged and composite code. It has an extensive range of open-source framework for the developers to choose from, some of which fall in the categories of full-stack web frameworks, while others are micro frameworks. Although not as popular as Python and JavaScript, PHP developers are still needed in large numbers.

PHP users: WordPress, Wikipedia and Yahoo heavily use PHP and has helped its popularity as a web language. Developers often use it for transferring databases or using SQL.

6. Ruby

The OOP language is very much in high demand, especially for startups. It supports in the procedural and functional programming notation and is very easy to use. It is a general-purpose scripting language so it is used in web applications, web servers, system utilities, database work and backups. The web-application framework which is implemented in Ruby is called as Ruby on Rails or RoR.

Ruby users: Airbnb, CrunchBase, GitHub are some of the popular platforms that use Ruby.

7. C#

Created by Microsoft, C# is widely used for backend programming. It is considered to be one of the most powerful programming languages in the Dot NET framework. It takes the help from an integrated development environment product that is Microsoft Visual C++ and is hence a popular choice for applications that are based on Windows, Android and iOS. The language is also widely used for building games (using Unity), building Window mobile phone apps and lots of other use cases.

C# users: Major companies like Accenture, Infosys, Netflix, Capital One need C# developers. The C# is used in a number of backend operations of many popular websites such as Dell, Bing, Visual Studio and Market Watch.

8. GoLang

The language made by Google supports for multithreading at large and is hence used by a lot of companies that rely heavily on distributed systems. It has goroutines instead of threads which consume almost 2KB memory from the heap. It provides a high performance like C/C++ and has efficient concurrency handling like Java.

GoLang users: Go is widely used in startups in Silicon Valley. Some of the Indian companies that use the language are Jabong and Razorpay. The core Go team works at Google. Google – the core Go team work at Google. Most uses of Go at Google are confidential. The YouTube team have released their MySQL scaling infrastructure as open source software.

Salaries for in-demand programming skills including Java and PHP are rising rapidly. Advertised tech salaries have grown for the third year in a row, up 1.7% in 2018, with pay for specialised tech roles increasing significantly, as demand for .NET, PHP and Java developers continues to expand.

Over that three-year period, Java developers have seen the largest increase in salaries – 41%. Their wages also increased 6% between 2018 and this year – the average Java developer earns £63,700, although that can rise to £70,700 according to the data from recruitment company Reed.

The second best-paid programming role was full-stack developer, which pays £53,500 on average, rising to £60,300. That’s up 5.6% on last year and 18.8% up on 2016.

PHP developers have seen salaries increase by 20.6% over the three-year period, and enjoyed the the largest increase of any tech role in the past year, up 6.9%. .NET developers have also seen a significant boost in salary during the period, with average pay increasing from £39,900 in 2016 to £47,400 this year – an 18.8% rise.

In most programming language popularity indexes JavaScript, Java, and Python are the most popular languages.    

Data scientist, data analyst, technical architect, DBA and network engineer have also all seen double-digit increases to salary over the three years.

Pay for the more business-focused roles, such as business analyst and project manager, has also risen, but by a smaller amount than for developer roles.

Indeed, one of the few jobs to see pay decline in the last three years, according to the data from Reed, is that of IT director, which it said dropped between 2016 and 2018, only to climb back up slightly this year. Overall, average IT director pay has dropped slightly over the period from £89,200 to £83,600.

These rising salaries are matched by increasing demand for staff with these skills, according to Reed: while the overall number of technology roles advertised increased by 10% since the start of 2018, specialist roles such as data scientist (20%), .NET developer (13%), and BI developer (13%), showed increases considerably higher than average. Demand for full-stack developers – a role that can demand many different developer skills – has also increased rapidly, with a 41% increase in roles advertised since the start of 2018.

The data comes from jobs posted on Reed’s website between 2015 and 2017 and the advertised salaries.

Andrew Gardner, director of Reed Technology, said: “There are plenty of roles out there for candidates with mobile experience and front-end development. Alongside that, firms will also need people with cloud-based experience, and storage skills. The impact of legislation such as GDPR is creating a lot of demand, with companies making sure they have the right skills, systems and processes in place – as a result roles in data are also growing.”
