IoT (Internet of Things) is creating a lot of buzzes everywhere. Various IoT applications of the technology include smart cities, smart wearables, smart home appliances, healthcare, automation, and other iot devices. But what is IoT?

You will find several definitions of the same over the internet but still, confusion stays. Basically, IoT architecture is a network of interrelated computing devices or machines capable of transferring data over a network.

Note that there is no need for any human-to-human or human-to-computer interaction in IoT. And with time, IoT is changing the world of technology. The trends that we have listed below are proof of that popularity.

We understand how precious time planning and management are during the quarantine days when we have to work from home due to the pandemic. Working from home for prolonged periods of time is different from working in your workspace.

The problem is, the more specific you are, the more people self-select out. And if you’re specific in the wrong ways, you’ll lose people that you’d love to have.

Gatling is an open-source performance testing framework, which uses Scala, Akka and Netty as a technology stack and as its backbone. The first Gatling release was in January 2012. Since then, Gatling has had a couple of major releases almost each year, as well as a pretty extensive popularity growth across the performance engineering community.    

As Gatling was created in order to write tests in the Scala programming language (which is a very powerful language but has a relatively small audience), you might think that this performance framework was designed mainly for a specific group of engineers or for limited needs. But if you check how many articles you can find about this framework in comparison to the other well-known open source load testing tools, you might be surprised, because its popularity stayed pretty strong over the past years.

Gatling Works Everywhere

Gatling is written in Scala, which allows you to run it on any system. That’s why you will never hit any trouble by using different local machines and cloud servers to run and create your tests.

Create Gatling Tests as Code

For many developers, it is a huge benefit if they can write performance tests as source code, as Gatling enables. This allows us to store tests under version control systems that enhance developers’ collaboration, keep historical changes clear and prevent us from losing the work we have done. In addition to that, code helps bootstrap the tests by refactoring, which is a powerful process in any popular code IDE application where you can write the Gatling tests.

Gatling has Detailed Metrics Dashboards Out of the Box

Gatling created detailed metrics dashboard that you can see after tests execution without having to add any additional plugins. The report is stored as an HTML file, which can be easily saved for some future analyses and metrics comparison. In addition to that, the report is interactive. which allows you to perform more detailed analyses and concentrate specific requests in addition to the overall picture.

Gatling is Powerful!

First, it’s worth saying that all performance tools should be powerful by the nature of their purpose. But Gatling definitely has an advantage over many other frameworks (like JMeter), because it uses advanced architecture and the Akka toolkit, which is based on the actor model that is distributed and fully asynchronous by design. Thanks to the Akka toolkit, Gatling doesn’t allocate a separate thread for each user. Instead, all multithreading is done via messages between  actors (universal primitives of concurrent computation), which allow to simulate a list of users by using just one thread.

Gatling has Capable Assertions

Gatling has an integrated assertions API, which gives you a full arsenal to perform functional assertions. This API allows you to run different types of functional checks along with your performance testing.

Gatling Uses Human Readable Tests

Gatling tests are very elegant, because Gatling defines a domain-specific language that allows writing very clear and human readable tests. This is important because it helps teammates work together on the same scenarios without spending time on additional knowledge transfer.

Gatling Provides Smooth Integration with Real Time Monitoring Tools

The outbreak of COVID-19 has hit the majority of countries and regions on this planet as 135 countries and territories reported confirmed cases on March 15. A record number of children and youth cannot continue their regular study life due to disruptions caused by the outbreak.

More than 60 countries in Africa, Asia, Europe, North America and South America have announced or implemented school and university closures. Indeed, the impact of COVID-19 on education has gone far beyond school closure. What is its impact on the global education landscape? How will it change the future of education in the aftermath?

First, health and life have become the first priority. The component of health, life and wellbeing in curriculum varies from country to country. It is also delivered in varied ways in classrooms and schools, as a standalone course, or integrated with physical education and mental wellbeing. Health emergency response is often absent either in curriculum or in school activities in many countries. Now almost all the governments and education authorities are producing guidelines and guidance to the students with proper measures and actions to avoid infection and stay safe in the case of virus infection. Health education, especially those relating to emergency response will be an integral part of curriculum and school administration in the future.

Online education becomes the norm. A record number of students in the world now rely on online education to continue their study due to COVID-19 quarantine and school closures. This is effective when national portals are available. Typically, China has created a national portal that can accommodate 50 million students learning online simultaneously. The outbreak has de facto accelerated the integration of technology and artificial intelligence in education. Nonetheless, lack of access to technology or good internet connectivity could also constrain access to learning for those from disadvantaged areas or families. The disparity and inequity is likely to enlarge.

How effectively students can learn depends on how schools and teachers can manage their learning. People were used to classroom-based lectures that have been critiqued as old mode for industrial society. Indeed the outbreak forced a leap into alternative approaches to learning with integration of technology and artificial intelligence. It demands new methods and strategies of learning assessment. The key to effective evaluation lies in cognitive and brain science that could identify solutions to effective learning. Learning science will play a larger role in future educational development.

Parent education levels pose a challenge to online teaching and learning. For many students who study online due to imposed social distancing, travel restriction or school closure, home turns into a classroom, and parents enter into the role of teaching assistant or learning partner whether they're prepared or not. Many parents struggle to perform this task, especially those with limited education and resources. On the other hand, working parents tend to leave children unattended, which may lead to varied quality of learning or even risky behavior. This warrants a close parent-school partnership as well as strong and supportive parental education, which have never been more important to the learning system than right now.

In addition, mental wellbeing counts. The outbreak, especially for those who have close contact with confirmed cases or experienced the death of a family member or friend, is a traumatic experience for children and young people. Stress and depression might increase as a result of a lack of social contact that used to occur through social activity and human interaction in schools. Social isolation, in the case of social distancing and school closure, might be compounded by anxiety arising from challenges with the new mode of online learning. Overall, the battle against coronavirus is a test of courage and perseverance for both individuals and nations. This has made mental wellbeing and mental consultancy one of the fundamental education elements in schools.

Apache Spark is a data processing system that can perform tasks simultaneously on very large databases rapidly and can also spread data processing tasks, either on its own or in combination with other distributed computing resources, through multiple devices. These two characteristics are fundamental to the worlds of big data analytics, which need vast computational power to be mobilized to smash through massive data stores.

The graphical representation of data and information is data visualization. Data visualization tools offer an interesting way of seeing and interpreting trends, outliers, and patterns in data by using visual elements such as charts, graphs, and maps.
