Everything You Need to Know About Refactoring: Improving the Quality of Your Coding

By | Coding

As your day-to-day business life changes, so will your needs regarding your internal computer services. The code you may currently have may be outdated or may no longer serve its purpose. 

There are two ways you can go about this situation: you can either completely replace the coding or refactor it. What does it mean to refactor your coding? It’s simple, refactoring refers to the process of taking old coding and reworking it to change the factoring and its functions without changing its external behaviors. This process is faster and may be beneficial to your business, but there is much more that goes into refactoring if this is a considerable option for you. 

We have all the information you need to learn more about whether refactoring could be useful to your applications. 

Why Refactoring is Important 

Refactoring is crucial because it yields many benefits. First off, refactoring can improve the overall design of your software. By rebuilding your current software, you can improve upon its architecture and quality. Refactoring your software and coding can also make it easier for both the programmers and computer users to understand your platform. Even better, when the code is easier to read and operate, your computers will be able to detect bugs or glitches within the coding much more easily. 

When You Must Refactor Coding

Now that you’re aware of the importance of refactoring is so important, it’s time to talk about when refactoring is most necessary or when it can be done. Whenever you need to add a new feature or functionality to your database, refactoring can implement the new change with ease because it already works to optimize your coding. It is also best to look into refactoring if your coding becomes confusing or simply does not suit your software-based needs. 

Testing Your Applications 

Before you begin to refactor your code, you have to test your current code to see where it stands. Once you conduct these tests, you can move on to refactoring. Testing your current software also allows you to see if any changes have been made to the coding, which shows you exactly where your coding might stand in terms of how well it serves you and your software. You don’t have to do complete testing either, you could simply run unit tests or integration tests, which take a quick look at your coding. 

Code Smells: An Indication of Error

“Code smell” is a term that indicates your coding is going bad and is no longer fulfilling its purpose. There are many factors that indicate a presence of code smell, or coding that poses a serious problem, including:

  • Redundant or identical code
  • Overcomplicated coding design 
  • Code that serves little purpose
  • Code that requires change/refactoring in one or more parts

These indications can become more apparent over time, as your software functions and requires change. The factors can start affecting your entire software if you don’t look into refactoring.

Techniques of Refactoring

Abstraction Technique 

The abstraction technique is one of many ways that refactoring can be done. This method is best to use when there are large portions of refactoring that need to be taken care of. Overall, the method of abstraction is to reduce unnecessary duplications in the software. Abstraction can be broken into sub-methods. For example, the pull-up/push-down method refactors in classes to eliminate code duplication with ease. Other sub-methods have specific ways of reworking the coding. 

Composing Method 

Just like the abstraction technique, the composing method also works to reduce duplications. The composing method utilizes extraction and inlining. Extraction breaks down the code into smaller code to make it easier to look at fragments and move them around in the coding. Inline refactoring looks to find how coding can be replaced and deleted, thus being simplified. 

Preparatory Refactoring

Another technique is preparatory refactoring. This method is best to use in refactoring when you want to add a new feature as you are cleaning up your coding. It makes new changes easier to implement if you have this done during refactoring. It can be considered a software update. This is best when it comes to reducing technical difficulties later on.

The Most Popular Cryptocurrencies

By | Uncategorized

A financial diagram displaying many different types of cryptocurrencyAlthough cryptocurrency is well-known across the world, it wasn’t always that way. The concept of cryptocurrency didn’t take full effect until 2009. The idea had been in the air before then, but it wasn’t until January of that year when Bitcoin—the most popular cryptocurrency there is—was fully conceived. 

Cryptocurrencies were made in an effort to secure transactions between two parties. Although this form of money is not tangible, it definitely takes a step up when it comes to security and digital services. 

In the past couple of years, other cryptocurrencies have arisen to join the ranks of the infamous Bitcoin. With an estimated 4,000 cryptocurrencies out there, how can one differentiate between them all? What makes each of them different? What does each have to offer? Let’s take a look. 


From elusive individuals who may not actually exist to conspiracy theories that delve deep into the dark web, the creation and history of the world’s most popular cryptocurrency are shrouded in mystery. 

One thing is certain, however; Bitcoin is the world’s leading cryptocurrency. It has dominated the market since early 2009 and it doesn’t look to stop anytime soon. In fact, Bitcoin has accounted for more than 69% of the cryptocurrency market. This cryptocurrency is well known for its uncertain lows and incredible highs. By the end of 2018, Bitcoin plummeted to approximately $3,000. As recently as January 2020, it peaked at $40,000. 


Litecoin debuted in 2011, a couple of years after Bitcoin. It is operated through a platform that is not controlled by any central authority and uses Scrypt as a proof of security. Scrypt can be decoded if need be. What Litecoin has over Bitcoin is that it operates to provide faster transactions and confirmations. There is an increasing number of merchants who are opting for Litecoin. 

Bitcoin Cash

A variation of Bitcoin, this is considered a fork to the original cryptocurrency. A “hard fork” is a drastic change to a network’s protocol that aims to make invalid transactions, valid. It can also operate to do the opposite should a valid transaction be confirmed as invalid. This source of cryptocurrency may have also been made to bring in more funding for the company. 


Ethereum is a decentralized software application that serves to promise less downtime, fraud elimination, maintenance and control, and the inability for anyone to interfere, especially third parties. Ethereum’s niche is to create a suite of financial products that anyone in the world can reach without having to worry about any kind of interference with their transactions. 

Binance Coin (BNB)

Binance Coin gets more into the specifics regarding the kinds of transactions people are making. Binance is dedicated to providing a payment method for those who are involved with trading on the platform, Binance Exchange. Those who use this form of cryptocurrency are entitled to trade at a discounted price. It is one of the most widely used exchanges in the world. 


Tether is a unique form of cryptocurrency, known as stablecoins, which attempt to point their market value to another form of currency in order to reduce rapid and unexpected changes between transactions. Tether is known as “a blockchain-enabled platform that is designed to facilitate the use of fiat currencies in a digitally-based manner”. In simpler terms, it allows individuals to make traditional transactions without the fear of something going wrong between the two parties. 


Stellar cryptocurrency is a decentralized platform, as well, which is supported by its parent, the Stellar Development Foundation. The main goal and operation of Stellar are to enable quick transactions at low costs. As opposed to using any other kind of algorithm, they work with and use their own algorithm, called “Stellar Consensus Protocol,” while simultaneously providing decentralization, security, and trust. 


Zcash, short for Zerocash protocol, is an imitation of the basic Bitcoin database. What sets this cryptocurrency apart from others is that it provides anonymity of transactions. With bitcoin, each transaction can be seen. It’s practically public information. Zcash wants to provide consumers with the ability to stay just as private as when consumers use cash to purchase services or products. With Zcash, there is no way the transaction can be tied to the party who made the purchase. 


Tron was able to thrive in the past year, where the entertainment industry had to take a hit. This is because Tron is a blockchain-based platform that is encompassed around sharing content. Tron does not aim to profit from gathering and selling data. Instead, it protects users and allows creators to monetize their content directly to its form of cryptocurrency.

It has hurt some and it has provided others with the opportunity to expand dramatically. Most importantly, COVID-19 has had a notable impact on businesses that specialize in technology and computer sciences. It is important to understand how the pandemic has affected these sectors considering we rely on technology and services of computer science more and more every day. In a positive sense, it has provided businesses, such as Marble Computer, with the opportunity to optimize technical functions in everyday obligations. We’re here to discuss the specifics regarding COVID-19’s effects on businesses like ours. 

Hardware and Software 

Although the supply of new hardware products is slowing down, this time in history has provided software and programming to grow extensively. We have witnessed a decrease in hardware products due to supply chain constraints. With that being said, companies that were able to work remotely before the pandemic are in high demand. Security software has been popularly requested by several business clients. It is obvious that prices for security software will increase and so will spending on these products. Furthermore, organizations are finding more and more value in securing endpoints, cloud-based tools, log management, and VPNs. 

IT Services

Similar to computer software companies, IT services and businesses are experiencing demands. IT spending is estimated to grow due to the need to invest in cloud infrastructure services and the installation of specialized software. We have already seen a large increase in telecommunication equipment and services as organizations feel compelled to further encourage interaction with employees and students as they operate from home.

Thanks to enhanced remote work scenarios, IT departments are expected to play a larger role in BCPs (business continuity plans) and will need help from software and programming experts in order to procure devices that obtain the necessary functions, languages, and security to function as desired. 

Lastly, IT services are given the responsibility of enhancing faster access to data and automation in order to allow businesses to rely on network and communication equipment at a speed like never before. This can speed up 5G network deployments and the adoption of 5G equipment overall. 

Network Equipment 

Network equipment, such as teleconferencing software, is increasing as more and more computer software and technology companies encourage employees to telecommute. This provides potential benefits for companies who already have these products deployed. It is important to consider that, similar to internet technology and products, faster access to data and automation allows people to keep consistency with their work and day-to-day work obligation. Network equipment is heavily relied on in order to curate communications that are fast, reliable, and deploy information at a rate that benefits businesses, customers, employees, and employers everywhere. 

The Effects on Employees and Company Teams

Computer software business and IT services are able to work remotely, despite what may be happening on a global scale. The dependability of these businesses has become a strain for some, however. Developers and professionals have been able to focus more and have been able to provide customers with the digital transformation they need to help their businesses thrive. However, some respondents have encountered several difficulties in the attempt to apply applications, software, and automation for businesses and clients in need. Overall, the transition to working from home has benefited software teams more than it has hurt them. It has provided them with opportunities to comprise new software strategies, thus accelerating many businesses. 

How to Move Forward

We can learn plenty about those who work in computer software, programming, and sectors of technology, especially as we witness how they can manage their services during a global crisis. Businesses with these focuses are expected to drive technology and computer product adoption to encourage innovation and to support the “future of” scenarios. Additionally, these companies plan to understand the supply and demand during the pandemic in order to develop more intricate inventory strategies. Lastly, businesses such as us intend on implementing a digitally-enabled future full of work tools that support business processing, automating, and back-office functions.

Industries that Rely on the Skills of Computer Programmers 

By | Uncategorized

Programmer working with program codeThe demand for skilled and experienced computer programmers continues to grow dramatically. As more and more businesses are making big digital moves, many business owners are finding themselves in need of computer programmers who can help them migrate their data in the most efficient and reliable manner possible. With that being said, programmers can be found beyond the technology field. Even more, professional programmers tend to be paid more in fields such as educational, accounting, web development, and more. With millions of more positions opening up, half of the job openings in the U.S. that require programming skills are outside of IT. We take a look at nine different industries that hire people with these intricate skills. 

Web Development 

Web development is a major industry that tends to rely on programming skills more than any other field (with the exception of technology). This industry has grown drastically in the past few decades, where graphic designers, web designers, and even video game developers find themselves in need of a professional programmer. Programmers help designers and developers with optimizing and navigating digital tools. 

Accounting and Finance 

This is where business-computer languages such as Python, Java, C++ come into the picture. Finance professionals and accountants heavily rely on these programs when it comes to specific services such as risk management, pricing, and trade management. Python is a preferred option for most business professionals. Employees in this field also rely on programmers to help them enhance their analytical tools. 

The Medical Field 

Medical professionals and doctors are responsible for keeping documents confidential and out of reach. They reach out to their health information managers to file these documents accordingly. Although, the job is made easier on health information managers with those who can work through and sort databases. This has become a very important skill, especially with the innovation of telehealth. 

Government Offices

Similar to medical facilities, government offices retain a heavy amount of confidential information and documentation. Government officials also opt for the skills of a computer programmer in order to help their employees do their jobs at a faster pace. With various reports coming in and out of government facilities, computer programmers are needed to help these workers expedite these arduous tasks. 

Retail Chains

Some small businesses may hire a computer programmer from time to time. Although big businesses, such as national chains, may find computer programming skills more suitable. With so many facilities of the same company, it may be quite the challenge to sort and analyze consumer data and statistics. Computer programmers can also help them optimize their applications when it comes to analyzing revenue and other expenditures. 


More and more students have begun to take up the practice of computer science and programming starting in high school. Within these courses, students are expected to prioritize and apply skills of logic, computation, organization, and collaboration. 

Additionally, computer programmers have been called into schools to help prepare interested students for courses that they will be taking in college and throughout their professional lives. Most importantly, students who want to go into computer programming are being taught coding languages with the programs that are made available to them. 


Similar to many other concentrations of work, marketing businesses are expanding into the digital realm. As of recent years, computer programmers have been rather essential to marketing companies. Those with programming experience may be placed in positions to perform technical skills that allow these businesses to design, create, and optimize their products and services. Software engineers are the computer programmers that can be found in these businesses. 


Although “business” is an umbrella term, many business-based careers require the skills of data analysis, which can often be found in those who specialize in computer programming. Either that or businesses will seek candidates that have a background in studying computer programming skills, such as analyzing data science and statistics. Similar to accounting, business sectors will look for those who know how to apply and translate Python. 


Mechanical engineers make up the vast majority of employees in manufacturing facilities. In fact, in most engineering settings, the six highest paying skills are all somewhat related to programming, Much like business and accounting, Python ranks as the best-paid engineering skill. Engineers are expected to handle many job tasks, where they might need to learn how to code, and how to translate these languages, on-site.

Your Questions, Answered: FAQs About Application Migration

By | Application Migration

As you may already know, application migration is the intricate process of relocating an application program from one setting to another. For example, you might want to migrate an application from the public cloud to a private cloud environment. Y0u may also take up migration to move from an on-premise server to a cloud provider’s environment. Although, not everyone who requires application migration may not understand the time and equipment necessary for a successful launch. Whatever the case may be, we’re sure you might have some questions regarding how exactly application migration works. We’re here to answer them. 

How long does the process usually take? 

The time required for a successful migration depends on how many servers are in the process of being relocated. If any re-platforming or refactoring is required, the time may be extended. Although, trained experts in the field can typically provide small to mid-sized businesses with three business days to complete the migration. To gain a better idea, we’ve outlined the time of completion required depending on the number of servers:

  • 25 servers – 3 business days
  • 26-100 servers – 7 business days
  • 101-500 or more – 15 business days

What are the main benefits of migration to the cloud?

By migrating your data and applications to the cloud, you can eliminate costs and there is no need to hire people to run the system for you. Even better, the security of these applications when being moved to the cloud is enhanced. Cloud providers allow investors to look into more resources to secure their applications. Most of all, the cloud provides the opportunity to store, access, and analyze almost an infinite amount of data. 

Can you migrate all data without any downtime?

Data can be migrated without any downtime. Our only involvement with your server will be the database backups and other assets as provided by your host. As long your data and applications remain stable and do not falter, there will be no need for downtime. After the migration has been launched, we will begin the testing process as your current servers operate independently, allowing you to store more data if need be. 

Will my current host be informed that I am migrating my applications?

In most cases, there is no need to inform your current host that you are migrating applications. Your host may not be aware of the migration until the move is complete, your services are live at the new host, and until you decommission your former hosting account or application. 

How can I test my site during the migration process?

Typically, your engineer will conduct high-level testing to complete the initial migration. Additionally, your engineering will provide you with a simple script and set of instructions to launch what is designed to conduct an update for your computer. You will be able to search and surf through your browser and navigate your applications even before the completion of the migration. If you come to find any issues during the testing site, it is your responsibility to make note of them and inform your engineer of them. 

What can I do in advance to support the process?

For the migration to run smoothly, all technical decisions and alterations must be made aware throughout your company. If the migration process is not thoroughly communicated throughout your departments, it is possible that even a thoroughly designed migration can be discarded altogether, with efforts and investments wasted. Additionally, you will want to clear any poor data management that way it doesn’t interfere with the process. 

Are there different migration strategies?

Several migration strategies typically include Rehost, Replatform, and Refactor. An engineer will most likely choose the quickest and most efficient option and then adapt the solution to the application, as necessary. With these strategies, the migration process provides customers with the opportunity to optimize old (and even outdated) applications and get rid of unnecessary features. Replacing obsolete tools can help you enhance how your application may run.
