Java - the base stone for programming software

By Vlad Ciontescu, a Java enthusiast

Last year I attended for the first time a Java community meeting – Devoxx Belgium. It is probably the best place to learn about software development methodologies, programming software, change ideas, promote projects and above all, get inspired. I gathered a new set of information about the possibilities that new technologies bring and left with a head full of ideas that I still think about experimenting with. Still, the most important things that I left with are the connection with the network found there and the concept of clean code that is the base for creating programming software.

The best part - the network

I’ll let you know about most of the things that tickled my fancy – which will bring us back to Java. I have a few inspiring ideas that run around my head into a short and clear perspective. Keep in mind that my preferences were highly influenced by the speakers. Also, I choose sessions that aim to help me in my professional development.

My favorite part of the show was by far the network that this kind of conference brings to life. The community formed by the dedicated developers leaves you with a set of intentions. And even more important it gives you the opportunity to be in the same room with most of the key persons. They work hard to take programming software, technologies, and software development methodologies to another level.

To many of the burning questions, I found answers somewhere in those rooms. Surrounded by other Java enthusiasts, I found them either in a talk or even in the middle of lunch with people of who’s mindsets and interests align.

Firstly, I am keen on many ideas that I previously encountered in different online talks and articles. This also means that I went to Devoxx with a set of insecurities and problems I wanted to solve.

Clean code and unit testing in programming software

The most important part of the conference was getting my mind blown away by all the things brought to life by Victor Rentea with his unique, energetic and full of passion style of presentation in subjects like clean code and unit testing.

Here is what I found most useful from these topics:

1. Clean code

The biggest problem encountered by devs is that code is read 10 times more often than it’s written in the programming software. Most of us can’t recall exactly how and why parts of the code were written in a certain way, and here is where these simple rules may come in handy:

  • The naming of variables, methods, and classes: clear naming is mandatory.
  • Methods should be short (one page in the IDE – 20 lines of code or preferably less).
  • Methods should not have more than three parameters.
  • Parameters should not be of type Boolean – at least not used as flags to request alternative behaviors of the method.
  • Methods that return a result should not have side effects; methods that return null can have a side effect; make clear in the name of the method what that side effect is.
  • Comments in code should rarely be used – the code should speak for itself. However, comments that reveal a workaround for non-trivial issues and bugs are valuable. Or that explains a special corner case.
  • (serious) Peer reviews should ensure that code does speak for itself.

2. Unit testing

Probably the biggest challenge of a developer. What does this solve? It mostly eliminates the fear induced by breaking the functionality while modifying or refactoring a legacy/ugly code. Even though unit testing introduces an overhead in the software development methodologies and process, the time spent on testing and bug fixing can be drastically reduced.

Scratching the surface - programming software

What I’ve written above just scratched the surface of what Devoxx has to offer for many developers around the world in terms of software development methodologies, programming software, and inspiration. As I said in the beginning, I’ve gone to Devoxx to find some answers and get rid of my insecurities and this is exactly what Victor’s talks did. I highly recommend watching Victor’s deep dive on clean code and also try some coding katas and why not get out of your comfort zone and do some TDD – Test Driven Development (satisfaction guaranteed).

I managed to overcome big insecurity in refactoring code written by developers with more experience than me and I also got inspired to challenge myself to try and implement some functionalities using TDD methodologies.

Devoxx is definitely a place to be present if you’re a Java developer.

Java – an evergreen language for software application development

software application developmen

Java – an evergreen language for software application development

Java can be easily considered “something old and something new” all in one, because its role in software application development has remained unchanged. It’s the first to-go programming language, the fast reliable and secure base for web applications, gaming consoles, cell phones and many more. No wonder the number of Java enthusiasts is continuously growing. In fact, 6 young interns just kick-started their careers in Java recently by successfully finishing their 8 weeks internship in AROBS.

The project

The youngsters’ challenge was, of course, connecting the dots between the new information received from their mentors and what they already know. Their purpose –  further develop the back-end part of an internal application – Meetups By AROBS. The app integrates different functionalities like creating events, attending them and reward for participation. During the 8 weeks, they had to work as a team and go through the entire process, from design to implementation and deploy. While reproducing on a smaller scale the workflow of a software application development.

The tech part

From working with a database, specifically MySQL, to using Spring, Spring Boot, Hibernate they took theory into practice. They also had the chance to learn and work with a few old school technologies like Servlet, JSP to get a better understanding of software application development fundamentals. Though we are speaking about technology, working with it also implies knowing how to ask for help.

Technically speaking, I learned new things that I will surely use in my future career as a software developer. On a less technical note, I learned to help and accept the help of others when needed. My recommendation for students is to take the chance of an internship, no matter the programming language or technology. The experience is a great sneak peek to the software developer career.” – Daria P., Java intern

Where does Java apply

Java is one of the most popular programming languages applied in software application development. The 6 interns have gained knowledge that opened the opportunity door to become our peers. Furthermore, some stepped among the hundreds of Java developers in AROBS that work every  day to offer the best software solutions.

Whether we talk about Travel software, Enterprise solutions,  software development relies a lot on the work of Java developers.

Cloud-ready applications – is it for you?

cloud-ready application

Cloud-ready applications – what are the benefits for you?

Cloud-ready applications might be the answer to our fast technological development of today. We witness a never-before growth of businesses. In no time small start-ups can scale up to global giants thanks to the power of technology. But a big company has very different needs than a small one. That is when the management should reflect on different enterprise solutions. And due to its flexibility, the tendency is to opt for cloud-ready applications.

As you start onboarding new employees or customers the need for more – hardware, more storage, maintenance operation, security – grows. The traditional way of doing business relies on on-site resources. On the other hand, the cloud-ready architecture permits a more diverse distribution of resources since the hosting is no longer local, it is virtual. This resource distribution is over a WAN (wide-area network).

Cloud-ready application – explained

Remember when you had a 30 MB memory stick because it was the highest technology available on the market? You had to keep all your important data on it. And every time you had some new data you had to delete previous ones to free up some space. You feel this limitation when you have your application running on-premise too.

Actually, you do make use of a cloud. Especially if you have an iPhone. Instead of keeping your photos on your phone you can keep them on the iCloud. The same principle applies when it comes to your business.

A cloud-ready application means that the tools you use for the everyday existence of your business like, communicational systems, customer management systems, billing systems, marketing systems, etc. are ready to be migrated into a cloud environment. This means possibly embracing the PaaS (platform-as-a-service) ability of the cloud.

Do cloud-ready applications enjoy all the benefits the cloud can offer?

The answer is no. Cloud-ready applications can benefit from a limited number of the benefits the cloud environment can offer. Why? Because the applications that need to be prepared for the cloud were created for the traditional environment. This means the application has to be analyzed and understood. You need to come up with an action list that has to be done in order to move the product to comply with the cloud requirements.

However, there are applications that can benefit from all a cloud can offer – but these were designed for the cloud. That is why we call them cloud-native.

It is a matter of understanding where your product is:

  • If you have a product that runs on your premise, then moving to a cloud-ready environment is the first rational step
  • If it is a new application, then the goal is to create cloud-native from scratch

Why cloud?

Did you know that in 2020 more than 90% of companies will be on the cloud? Also, by 2023 this market will reach over $620 billion (according to stats from Report Linker). We got here because of the wide range of benefits of cloud computing like:

  • the easy of scalability
  • security
  • cost-saving (if cloud provider, services used, etc., are properly chosen)

Move your business to the cloud for better efficiency. Our experts can help you understand the necessary steps and the TCO for a cloud-ready movement to assure a maximized ROI for your business.  If you are looking for cloud-native or customized enterprise solutions, find out more, here.

Healthcare management software – the key change in the medical industry

Healthcare Management Software

Healthcare management software - the key change in medical industry

Healthcare management software is vital for health,  and health has always been a priority. Patient-care, in particular, has developed a wider spectrum over time and requires a constant upgrade from the medical system regarding the value of services provided. Moreover, the main engine for improved quality and innovation is technology. And healthcare management software is the most efficient form of an upgrade in this direction. Actually, the global digital health market is estimated to reach close to 200 billion dollars by this year according to statista.com. So, healthcare management software can be the best thing to invest in the near future.

Be in the arena

People are tech-savvy now and it’s ordinary for them to control their health via wearable apps. As an outcome, hospitals, pharmaceutical, and clinical trial companies, as well as other stakeholders of the medical niche, are always looking for the next best healthcare management software. Technology is key to help them keep up with the new healthy habits and deliver better patient care and experience. A good healthcare software solution makes a big difference in the whole process – from employee efficiency, better data management, and services, to a smoother experience for the patient when he interacts with the system. Using technology in the operational part is vital for the end consumer and also for keeping your competitive advantages.

The paper era has ended

If you’re in the healthcare business for some time now, you already know that paperwork in such a complex system is outdated. Transferring all the data from EHR (electronic health records), EMR (electronic medical records), HIS (hospital information system), healthcare CRM, dental practice management software (DPMS), picture archiving and communication systems (PACS), radiology information systems (RIS) and other medical procedures, into a protected digital form is vital. The workflow is more fluid and the focus is narrowed down to patient care rather than completing and searching for information in piles of collected data. Not to mention that these online platforms enable the use of portals where patients interact more directly and easier with your medical unit. They can schedule appointments and have records of their medical history. Also, the massive amount of big data is put in good use. Problems like inefficient treatments and processes are identified and replaced with better alternatives. Even more, clinical, financial and operational data can lead to a reduction of costs.

Must have in healthcare software management

Technology nowadays is easy to adopt, though, in particular fields like healthcare business, you need to give a closer look at certain matters of standards and confidentiality regulated by the institutions that manage the industry. But not least, look at your implementation plan.

  1. HIPAA-compliancehealthcare software solutions work with a great volume of data that are processed and stored. But is this data in safekeeping from digital breaches? To make sure of that, always make your software HIPAA-compliant.
  2. FDA-compliant – the FDA is responsible for promoting the development and production of high-quality devices by medical manufacturers in the US. That includes the integrated software that the devices use. Being FDA-compliant means reaching and keeping all these standards.
  3. Coherent strategy – Big systems can’t change overnight. So you have to put everything into a strategic plan to replace the old system with the new approach. Nevertheless, with a good communication plan, the transition is more bearable.

Healthcare management software providers create room for constant improvement in the medical system. And the trend is obviously only growing and developing more and more innovative solutions.

If you want to be in line with your competitors, solutions are one click away.

wireless home automation system

Is the wireless home automation system a good investment?

Nowadays, the wireless home automation system comes with so much developed technology that it’s simply impossible not having where to choose if you want to use to turn your house into a smart home.

Thanks to IoT software development, a wireless home automation system can be life-changing. Therefore, using it can make your existence much easier because it allows any user to control an electrical device from the computer or smartphone.

Before investing in a home automation system, make sure you find the right one for yourself. Moreover, maybe you would like to consider the technology used by the product and compatibility with your device.

Which are the most frequently used technologies in the wireless home automation system?

Wi-Fi

Do you have an existing Wi-Fi network in your house? Suddenly everything becomes easy. The smart home appliances are designed to function with the existing Wi-Fi network. However, too many appliances connected to the same network can slow down the response from those devices. Keep in mind that Wi-Fi is a power-hungry technology.

Li-Fi

This relatively new technology uses light for device communication. Using the Li-Fi technology comes with some advantages such as a wider bandwidth channel, functions in areas susceptible to electromagnetic interference and has a notably higher speed. Those of you who are energy conscious, you might want to take into consideration this technology. It is also preferred over Wi-Fi, Bluetooth or IR.

Bluetooth

The good old Bluetooth is now used by companies that produce smart light bulbs and smart door locks. Using this technology in a wireless home automation system comes with some advantages. It consumes less power than the previous protocols and we can connect multiple products that have the same connectivity features.

Z-Wave

Using the same protocol as Wi-Fi, radio frequency, the Z-Wave technology is in many ways different. It is energy-saving, enhances the communication between devices and is compatible with many brands. The protocol applies to thermostats, windows, security systems, locks and even to swimming pools.

ZigBee

Initially built for a commercial purpose this advanced protocol is now in residential usage as well. It is a low-power, low-cost based on radio frequency protocol used to create personal area networks. The protocol is highly customizable, can operate on multiple devices at a time, uses less power and can eliminate the battery usage.

Should we invest in a wireless home automation system?

The answer is… yes. This kind of system, even if it implies a higher cost at the beginning, to install all this smart technology in your home, you must think about it as a lifetime investment, enhancing the value of your house. It offers:

  • safety by giving you the possibility to install all those security systems,
  • convenience, making your life easier
  • savings of energy and money
  • highly customizable
  • easy to install
 

Whether you choose to use it or not, the smart home industry is in full development. The companies and professionals are working hard to deliver a better and more cost-efficient technology, affordable for many.
