A Sneak Peak into How Smart Buildings Work

6 days ago

Technology is rapidly moving forward, and we are already seeing how far the IoT world has come. Not only is it now possible to make your own smart home, but companies are looking into making smart buildings.

If you are wondering how all this is made possible, keep reading, because we are going to take a sneak peak into how smart buildings actually work. The most important things we are going to mention are sensors, and the role of big data in the whole process. Let’s dig in a little bit, and take a look at what makes smart buildings tick.

A foundation of sensors

In order for a building to become a “smart” building, it is necessary to deploy a wide array of sensors across the whole structure. The advent of Internet of Things, and the drastic transformation it has introduced in the segment of technology and connected machines, has a lot to do with how different types of IoT sensors developed over the recent times have helped IoT platforms function and deliver valorous kind of intelligence and data.

Some sensors check whether the person is in the apartment or not. Others measure the inside and outside temperature. Some sensors can measure how many people are going in and out of the building, whereas more of them can be used for tracking the number of free parking spaces.

There are literally thousands of places where sensors can be deployed. The more sensors there are, the “smarter” the building is going to be. They are used to collect various data about the interior and exterior conditions. This collection of data is crucial for the functioning of the whole system, which brings us to another element of the “smart” structure.

How does the whole puzzle fit together?

As you can see in the image above, a smart building relies on a series of systems and sensors that enable it to function.

  • Solar panel - At the top of the building, solar panels convert solar energy into power. This energy is used to power the whole building, including the whole smart network.
  • LIghting and illumination sensors - These sensors are placed inside the building space, and they provide the right amount of illumination for residents in the building. This ensures optimized power expenditure. Additionally, with motion sensors included, the door function is automated, as well as the whole lighting system.
  • Security - Security sensors serve to detect and record any type of motion in the building space.
  • Temperature sensors and air-conditioning - A series of sensors such as temperature and humidity, serve to accumulate data about inside thermal conditions. The information is used to feed the air-conditioning system that is always working on ensuring the right living conditions.
  • Energy storage systems - Not all of the energy collected through the solar panels is going to be used. In fact, during the days when the most energy is collected, people are usually at work, and this is the period when excess power should be stored somewhere. A smart building needs to have some type of power a storage system, ie. batteries, where energy for the future use is going to be stored.
  • Electric vehicles charging system - As technology is moving forward, we can now see a higher presence of electric vehicles in the market. The smart building uses the stored energy to charge the building resident’s vehicles.

Additionally, sensors in the parking lot and charging stations can visually present how many parking spots are available at all times.

  • Building management system - All of the abovementioned sensors collect data and store it in the building management systems. There, a manager can visually perceive all of the data about the building. Furthermore, this information storage system is connected to the world wide web, making it possible to feed information to the building residents no matter where they are.

Also, the building system is connected to the whole smart grid, sharing information with other buildings, allowing it to optimize energy expenditure even better in the future.

As you can see, the whole system functions together. The information collected through the sensors is visually presented to the system managers, allowing them to perform settings that allow the whole system to be eco-friendly, by optimizing energy expenditure.

What’s the end result?

The end result of a smart building is optimized expenditure. Over time, the building learns the behavioral patterns of the people living inside, as well as the outside weather patterns. It all leads to lower bills, as you save electricity during this process.

Furthermore, the residents of the building can rely on better automation, and implementation of technologies that makes it easy to lock or unlock their doors. There is more remote control over the apartment appliances, creating better living conditions for the resident.

As you can see, a smart building relies heavily on sensors, networks and data accumulation. Sensors pick up the information, then it is analyzed and used in the future.

The process sounds simple enough, but in fact, a lot of IT knowledge is necessary to set up such a network. This is only a sneak peak into how the smart buildings of the future will work. With the development of AI, automation is surely going to become even better, as AI will have better predictions, further optimizing the energy expenditure of the whole system.

In today’s world, any top IoT application development company looks to experiment different combinations of technology, machine learning and artificial intelligence to IoTize and build solutions around it to deliver intelligence and improved performance.

Planning to Hire Freelance Java Developer Top 11 Questions You Must Ask

Planning to Hire Freelance Java Developer? Top 10 Questions You Must Ask

Hiring a full stack senior freelance Java developer for a one-time project can turn out to be an expensive endeavor. This is why, lately, the trend of hiring freelancers is emerging in all industries that require the services of Java developers. Fortunately, there are enough of them on the market, willing to sell their services to the highest bidder.

But, from the perspective of a business owner, it is not that easy to find a reliable freelance Java developer who will do the job perfectly and on time. Let’s get one thing straight right from the start. For experienced freelance Java developers, you will have to pay anywhere from 30-60 US dollars per hour.

Anyhow, it is better to ask some questions before you hand the project into the freelancer’s hands. These questions will help you determine who is the perfect freelance Java developer for you.

1) Are multitasking and multithreading the same thing?

The answer you should expect is a resounding no. If you get that answer, you should ask the developer to be more specific and to tell you more about both. Here is the answer you are looking for.

Multitasking refers to actions that include simultaneous activities on the computer. There are two types. The first one is named preemptive multitasking. The system automatically pre-empties the running process to another processor. In this scenario, the user is not involved. Non-preemptive multitasking is when the computer has to ask for the user’s confirmation before any process is executed.

On the other hand, multithreading means that the program can manipulate the functionality of multitasking. It divides the program into a thread. After that, each individual thread utilizes the CPU and memory resources as a standalone process. One process can contain multiple threads.

2) Which loop concepts are there in Java?

Loops are very commonly used in programming. A loop concept executes a line of code over and over. Basically, you will have to dig to find a program written in Java that doesn’t use any loops. The answer you are looking for is 3. And, here they are:

For Loop – this is the standard loop concept. It is used to repeat a task a specific number of times. This loop is used when you know how many time the action has to be repeated.

While Loop – programmers use this loop when there is the need to execute a line of code only when a certain condition is met. Before executing statements, this loop checks if the condition has been satisfied.

Do-while Loop – this loop is a mirrored while loop concept. In this loop, statements are executed first, and the loop checks at the end if the conditions are met for breaking out of loop.

3) What are basic Java collections framework interfaces and their advantages?

Java developers must know about Collections as they are core building blocks for using data structures and it reduces development efforts, they are dynamic in size. They also supports thread safety and generic classes.

Experience freelance java developers must know about implementation of basic interface of collections framework and hands on practice of using following.

Map: Every object stored as key-value pair. Direct implementation of map are HasMap, HashTables, TreeMap. They are used based on requirements like concurrently, data ordering.

Set: Elements are stored with condition that no duplicate elements are allowed. Direct implementation of Set are HashSet, LinkedHashSet, TreeSet.

List: This collection allows duplicate elements to be stored, implementation of this collection framework is done via LinkedList, Vector and ArrayList.

4) How are the threads created? Which one do you use and why?

This is very important, as you want to hire the programmer who is able to build an app that most optimally uses all available resources. Threads can be created in three different ways:

Extending a thread class

Implementing a Runnable interface

The application can create a thread pool by using the Executor framework

Experienced freelance Java developers prefer using a Runnable interface. When you use this interface, there will be no need for objects to inherit the thread class. If your application requires using multiple inheritance, the Java developer you are contacting should know that only interfaces can help you. A runnable interface is very easily implemented and improves the efficiency of your program.

5) How would you store the sensitive data of app users and why?

This answer will help you determine how well the developer is dedicated to their call and whether he or she can extend their knowledge for various purposes.

The answer you are looking for is storing the sensitive data in mutable objects, such as the character array. Once the data has been stored, you can set it to blank so that it is no longer retained in memory and available for exploiting by using a simple memory dump extraction. Storing sensitive data in strings is bad, end of story.

6) What should you avoid when designing an abstract class?

This is a tricky one. The answer you are looking for is avoiding calling abstract methods inside the abstract class constructor. The main problem here is the initialization order. The parent class has to run first, so that the subclass constructor can run as well.

The main reason why this should be avoided is because it places a restriction on how abstract methods can be implemented. If some variable assignments occur after the constructor runs, you will now have access to those in later instances.

7) You code compiles perfectly, but the library is causing the NoClassDefFoundError or NoSuchMethodError. What is going on?

Most Java projects incorporate countless dependencies. All of these dependencies are loaded on the same class path and, in order to handle them, one has to use specific tools, such as Gradle, Ivy, SBT, etc. Using this tools is important. Why? Because when using one of them, you can’t add multiple versions of the same library to the project.

The error messages from above get printed out when there are two libraries in the project that rely on different versions of the same dependency. This happens because Java doesn’t use static linking like some other programming languages do, like C++, for instance. Fixing this issue requires some time and patience. It is important to start from generating dependency reports so that one can see which JAR has a dependency to which libraries.

8) What are enums and how can they be used?

It is always good to check if the Java developer has extensive knowledge on the platform he or she uses. The answer you want to have here should be something like this.

Enums are classes. But, not just any classes; they are final classes with a fixed number of instances. Enums can’t extend another class but they can implement interfaces.

Enums should definitely be used instead of integer constants, as they are flexible and safe to use. Enums can be used in any instance where there is a need for strategy patterns.

9) In Java, can an interface extend to multiple interfaces?

This is a really, really tricky question. It will help you, as an interviewer, see if your candidate is able to think quickly. Also, being able to answer this questions requires extensive knowledge on polymorphism, classes, inheritance, objects, etc.

Java doesn’t have multiple inheritance. This is the main reason why many job candidates may answer “No” to this question. The fact is that this is quite possible and the answer should be yes. The class is the one that can’t extend multiple classes, while the interface can always extend to multiple interfaces.

Make sure not to give up on candidates that say “No” at first and change their answer later on, explaining why they have changed their mind. On the other hand, if you get a resounding “Yes”, make sure to ask why. Some people may know the answers by heart; trust us, you don’t want them developing software for you.

10) Tell me the difference between Errors, Unchecked Exception, and Checked Exception?

Knowing how to handle errors and exceptions is very important for every Java Developer. All of the above mentioned indicate something different. Handling exceptions is especially important when designing large applications.

Errors are more important and more significant than exceptions. They indicate that there is a serious problem that deserves immediate attention. Resolving errors is hard and it usually requires a significant amount of time.

Exceptions are objects. And, any object can be thrown as an exception as long as it is an object the classes of which descend from Throwable. There are two types of exceptions:

Unchecked Exception – this one inherits from the RuntimeException and treated differently by the Java Virtual Machine. There are usually conditions that reflect errors in the program’s logic.

Checked Exception – this one inherits from the Exception-class. These are invalid conditions in areas outside the immediate control of the program.

11) What are System.gc(), Runtime.gc() and finalize() methods for?

Resource management is quite important in modern Java development. By asking this question, you will check if your job applicant knows the basic garbage collector’s methods. Besides, this question is also a tricky one, because System.gc() and Runtime.gc() are effectively equivalent. There is some difference though; Runtime,gc() is an instance method while System.gc() is a class method. System.gc*() is more convenient for coding, and it suggests to the Java Virtual Machine to start garbage collection.

Finalize() method is called by the garbage collector. When using the finalize() method, it is advised to release resources that are being held by the object inside the finalize() method.

Well, there you go. If you get satisfying answers to all these questions, don’t lose time, hire the freelancer that has answered them. In case you still have any doubts or you generally feel unsure, interview more candidates. This way, you can compare them and go with the one that got all the answers right and seems the best for you to cooperate with.
