Samsung Latest Tests With 6G Connectivity

Technology advances at incredible rates. Although we are not in full transition to 5G connectivity, manufacturers are already testing their proposals for the future 6G.

The University of California team of researchers has teamed up with Samsung to complete new tests around a new transmitter and receiver developed by Mark Rodwell, UCSB Professor of Electrical and Computer Engineering, in 2017. These tests have been completed successfully — with this receiver, with a capacity of 140 GHz.

The key to this frequency is that it exceeds 100 GHz, entering the Terahertz (THz) spectrum. An improvement of about 50 times over 5G, which exists in a frequency range of 40 GHz maximum. In addition, this ultra-fast 6G promises to reduce latency in an extreme way — to a tenth of the current 5G.

In addition to the 140 GHz frequency, the transmitter and receiver have a 2 GHz bandwidth. Tests carried out by Samsung allowed data to be transmitted at a speed of 6.2 Gbps at a distance of 15 meters.

But without a doubt, another of the great keys to this 6G connectivity lies in latency. According to Samsung tests, latency over 5G could be reduced to “one-tenth,” making the time lag between sending and receiving information virtually instantaneous.

Thanks to the scope of the terahertz frequencies, Samsung assures that the 6G would allow reaching potential speeds of up to 1 terabyte per second. These speeds could be achieved if these 6G networks operated in the less-used terahertz spectrum, beyond the radio spectrum.

However, we must understand that these tests show the potential of the network and not so much a real scenario that would occur in the consumer market. In fact, it would be difficult for a user to emulate these speeds, especially considering that very few would need to transmit 1 terabyte per second.

5G connectivity has promised speeds in smartphones much higher than what we managed with the current 4G connectivity. Without going any further, the standard has been handling speeds between 10 and 20 times higher than 4G, with peaks of up to 2 Gbps and a latency of between 1 and 2 milliseconds.

Water pollution is a critical issue threatening populations across the planet, and though some of us might not even notice it, billions of people around the world have limited access to clean water. Luckily, we live in times when technology can help create a better world for everyone, but how can a single student contribute to the betterment of humanity? Let us find out and see how you can make a change that matters.

Mind Your Habits

Though it is not exactly a gadget or a tool, it is the essential thing you must keep in mind – your own habits. Some of the basic pieces of advice on how you can help keep the water cleaner you can find in most essays about water pollution is to avoid disposing of household chemicals down the toilet or the sink. If you go through the free essays on water pollution, you’ll also find that it is not recommended to avoid using your toilet as a trash basket – do not throw paper and other items in there. These simple things will help you keep the water at least somewhat cleaner.

Full Load

A dishwasher or a laundry machine are essential gadgets that make our lives so much more convenient, but they also use and pollute considerable amounts of liquid. That is why it is recommended that you only use these utilities only when they are loaded to their full capacity. That way, you can reduce water pollution and waste to at least a small degree.

Water Filters

Yes, that might seem obvious, but the filters might actually make a real difference. They do not just help you drink clean liquid but also help the environment by reducing the presence of heavy metals and chemicals in the tap water. What some of the free essays on environment omit is that there are regions where tap water is completely undrinkable and that people cannot just pour themselves a glass of water. That is why water filters are essential for solving the water pollution problem.

Be Active

As a student, you have the time and energy to put into bettering the world around you, and you can surely make a difference. The best idea here is to organize a hazardous waste collection day on your campus. What does it have to do with technology? Well, you can use social media to spread the word about your initiative.

As said, it is not recommended to flush household chemicals and items down the toilet or a sink, but what do you do with those? Well, that is where you and your initiative step in – you can spread the information about the waste collection day across your university, ask the teacher to talk about it during the lesson, and talk about it online. Then, you can get people to throw the household chemicals into specific trash bins and then send those chemicals for recycling. This will help reduce the pollution in your region by a lot.

Water Efficient Bathroom

Right now, there are all sorts of bathroom utensils that save water – toilets and showers – all of that can be improved to save more water. If you don’t have the money, you can just put a couple of bricks or other large heavy objects into your toilet tank to reduce the amount of liquid in it, and consequently, the amount of water used during each flush. You can buy an efficient showerhead too, they are not too expensive, and they reduce the amount of water lost during the shower. All of these tools can help you reduce your environmental footprint, reduce the amount of water you use, and make it at least somewhat cleaner.

Wrap Up

What we all need to remember is that even a small act can make a big difference. Some people think that there’s no point in changing their habits because it would result in no change on a global scale. Billions of people adopt this line of thinking, which is really unfortunate. Our education has to focus on the environmental consciousness of people and educate them on how their small actions can lead to grandiose results that change the world for the better.

This AI-Powered App Will Detect If A Person Has Depression Just By Listening To Voice

The technology industry has evolved so much that a variety of devices are now used to assist the healthcare sector. Researchers at the University of Maryland in the United States are creating an application that can detect depression from the sound of the voice.

According to researchers, a person’s voice changes when they are depressed and that those who have this disease tend to express themselves and speak more slowly. For this reason, they are developing an application capable of detecting the sound of the voice using artificial intelligence that will help to find depression.

The project is led by Carol Espy-Wilson, professor of electrical and computer engineering at the university. During the 180th Meeting of the American Acoustics Society, the researcher discussed how the state of mental health of a person is reflected in the coordination of speech gestures and took the opportunity to announce the development of the application.

The app has no name yet and is in the early stages of development. However, Carol Espy-Wilson has noted that it would be recommended to patients to help them monitor them in their therapy sessions.

“Ideally, therapists will give the application to those patients who suffer from a major depressive disorder when they are in remission or if they only have mild depression,” said the professor.

The app uses machine learning, a technique that involves simulating the brain’s neural networks to detect subtle changes in speech patterns. To do this, the user will log in to the application for mobile devices and will then have to respond by voice to a series of basic questions about their status.

The user will record their responses verbally, and the application, through the smartphone, can capture video of the user while he talks, as long as the camera is turned on.

In this way, machine learning techniques will be able to assess the mental well-being of the patient. In addition, specialists will also be able to observe your articulatory coordination, facial movements and language to be able to determine the severity of the depression illness that you suffer.

Patients could use the app from home to send video and audio updates on their mood. The app will then evaluate it to help keep both the user and those around them informed of any worrisome changes.

Despite being still in development, researchers are already working on new functions to better fine-tune the application and also be able to measure the severity of depression.

Learning to Code Online is Summer Fun for Kids

There are different ways for children to have unbridled fun in the summer. Playing and exploring in the Great Outdoors is fantastic, but many kids feel at home with video games.

Parents are understandably wary about their kids spending too much time indoors on screens, but learning to code video games is a productive and valuable hobby that kids genuinely love!

Please keep reading to learn more about what you can expect from summer sessions in the best online coding programs.

Daily Sessions for a Deep Dive

Some of the best online coding classes for kids offer summer sessions that are structured more like a boot camp, where students spend a week or two learning every day for a few hours at a time rather than in weekly sessions.

The frequency of the sessions helps students take a deep dive into material that may be new to them, so they feel comfortable in the world of coding right away. The coding lessons will teach kids how to program their own video games, so while the substance of coding may be new, it’s taught within a framework they understand.

Small Classrooms with Young Teachers

Learning is more accessible when students don’t need to compete with their peers for their teacher’s attention, especially when they are young and the material is new. Ideally, online coding classes should have a ratio of four students per teacher.

It’s also essential that children learn how to program video games from teachers who also grew up playing them. Video games have a firm hold on adults looking back on the unadulterated pleasures of youth, and a teacher’s infectious joy trickles down to their students.

Kids need to learn from people with Computer Engineering or Computer Science backgrounds who know first-hand what it’s like to be a child who loves gaming.

Professional Coding Languages

Just because learning to code is so much fun doesn’t mean kids won’t learn core STEM skills and the actual coding languages professional programmers use all the time. Some programs teach drag-and-drop languages like Scratch, which gives beginners a sense of what coding is like.

But when it comes time to using coding skills later in the classroom or the workplace, it’s better to know the languages that video games and apps are built on, like Java, Unity, C#, C++, and more. If your child is lucky enough to go to a school that teaches programming, they’ll have a leg up.

It may seem surprising, but children can learn the very languages used to build games and apps that end up netting companies billions of dollars. Whether your child is learning to code for their eventual entry into the job market or simply to have some summer fun, they should learn professional coding languages.

Children love video games, and they’ll love programming them even more! This summer, enroll your child in online coding classes so they can program their own games.

Facebook’s New Tool Detects Deepfakes And Track Their Source

The Facebook AI team, in collaboration with Michigan State University, has presented a research approach “of detecting and attributing deepfakes” that is based on “reverse engineering from a single AI-generated image to the generative model used to produce it.”

This technology can be useful for Facebook to track the distributors of deepfakes – both simple disinformation and pornographic images — on its social networks. The development of the tool has not yet been completed and it is not yet ready for deployment.

According to Facebook, previous discussions have been limited to finding out whether a picture is real or whether it was created as a deepfake. The approach followed by the researchers is what is known as reverse engineering, which aims to uncover the “unique patterns behind the AI model used to generate a single deepfake image.” When comparing several images, it can also be determined whether they may have been created with the same model.

The team initially relies on the recognition of so-called fingerprints. These can also be found in a similar way in non-generated images that reveal the camera model used or the sensor. According to the researchers, such unique patterns in the image are also left behind by the generative machine learning models that generate the deepfakes.

The approach pursued also tries to derive individual properties of the models actually used from the fingerprints in order to draw conclusions about their network size and thus their architecture. This differs in different models so that they can be recognized and kept apart. According to the explanation, this already works in the first attempts.

Research leader Tal Hassner said that identifying the traits of unknown models is important because the software for creating deepfakes is easy to customize. This potentially allows attackers to cover their tracks if investigators try to trace their actions.

With its research, Facebook hopes to create tools for third parties “to better investigate incidents of coordinated disinformation using deepfakes, as well as open up new directions for future research.”

What is PRD and how to write it?

It is understood that PRD is all about promoting the product manager and communicating product features. It presents the intent of the product to the reader with clear and concise statements. PRD readers typically include developers, designers, testers, and even products.

Responsible for the project (usually the project director. And the head of the company, the situation in each company is different. PRD is not only a detailed description of product features. But also the role of PRD in being an implementation standard for product quality control. With https://fireart.studio/blog/how-to-write-an-effective-product-requirements-document-prd/ all the tasks can be easily carried out.

1 What should a PRD include?

What should a PRD include?

Product name

The product name is a general description of the document.

Description of function

Function descriptions are entered in detail and others can be saved. Too much document can cause interference. Hence, it is necessary to simplify and improve readability to show that the intent of the product is most valuable.

In a specific functional description, there are often use some other methods. These are such as product function structure, product information structure, user use process.

Product project personnel define requirements through discussion and then focus on requirements. It decomposes and assign tasks, monitor progress, test, and release.

This method is currently mainly used in the more common agile development model. These internet companies are putting more emphasis on communication, openness. And will be fast resolution. It’s difficult to say if this method is good or not.

To sum up

Ultimately, the PRD is still a professional document. And professional terms and vocabulary are necessary, but this does not mean that the more professional the vocabulary, the better. An overwhelming professional vocabulary is the most unsuccessful PRD. It is recommended to use professional language as much as possible for professional expression. Because ease of understanding and operation is the more important mission of PRD. After writing a document is finished with Fireart, it fully corresponds to all the expectations. They will come up with different opinions and questions. In fact, this is very good. Correcting a path is also the process of finding the problem.

Since PRD is dedicated to interpreting product requirements, there are many sizes and functions, and the relationship between different functional points is close. This requires the logic of the product manager to be very clear and to express abstract thinking concretely. This is hard requirement for the product manager. Thinking depends on innate factors, it was also mentioned above that we can use software tools to help in the implementation. There are many forms of expression such as prototypes, processes or other forms. Form and format are not important, remember everything in order to communicate clearly.

Clubhouse Has A Powerful New Competitor: Spotify Launches Spotify Greenroom

Inspired by Clubhouse, Spotify has just announced a new application — Spotify Greenrooms, designed to create audio rooms between different people.

Instagram, Reddit, Telegram, Twitter and LinkedIn are just a few names that have joined the bandwagon of virtual audio rooms. And now Spotify joins the rest too.

Spotify Greenroom allows you to create and join live audio rooms with a series of speakers and an associated audience. Selected speakers speak on a topic, and users listen to and interact with the talk. The application can now be downloaded from the Google Play Store.

To create a new chat room, we can use a Spotify account since we have the same username and password in both applications. However, if we do not use Spotify, we can create a new account on Greenrooms. Both creating rooms and joining them will be completely free.

But let’s not forget that Spotify’s core business is streaming music and podcasts. And from the company, they know that a good part of the Greenroom community will be made up of the artists already existing on the platform and their audience. Therefore, Spotify has already announced a fund for creators seeking to monetize this experience.

This fund will allow Greenroom creators to receive payments from Spotify, as long as they have certain popularity. Spotify has made a form available to creators so they can sign up for this fund.

One of the advantages of Spotify Greenroom, if we compare it with direct alternatives, is that here we can record the audio sessions so that later we can download them to listen or to upload them to other platforms. Perhaps Spotify is thinking of collaterally boosting its podcasting section.

3 Things To Do When You Encounter Errors in Your Coding

June 17, 2021

Programming, although fun, can also be painful. That is especially true for new programmers, who make a lot of mistakes during their early days. Besides, coding becomes unbearable when you encounter the same errors no matter how many times you change the code.

For such situations, here are three things you should do to get rid of the errors in your coding assignments.

#1 Understand the Type of Error

Before you do anything else, you must first understand the nature of your error. To deal with unwanted errors in your code, you will have to know, not only where they are, but also the reason why they are popping up. You cannot debug your code unless you are aware of the error and what is causing it.

Programming errors can be divided into three groups. These are syntax error, logic error, and runtime error.

Syntax errors are common. These errors are seen when you misspell the name of a statement or keyword. For instance, instead of writing ‘print’, you wrote ‘prin’. Syntax errors are also seen when you try to use a variable that does not exist or when you forget to close a bracket. Your code will not run if it has these errors. The IDE will be quick to point out where you went wrong, and what case of syntax error your code has.

Logic errors are a bit difficult to debug in the sense that your code will still run even if it has these errors. Despite running successfully, the code will not show the expected results. Sometimes, it might even enter an infinite loop if you are using loops and forget to set a stopping point or add increments to the loop counter.

You might encounter a runtime error for a few reasons. In most cases, it is because you are using an array index that does not exist (array out of bounds error). Or it could also be that you are trying to refer to a missing file or variable, or trying to call an invalid function. In the development sector, runtime errors are often referred to as bugs.

#2 Debugging Your Code

Debugging is something that every professional programmer needs to learn. And you have to cultivate that practice from an early age.

There are many ways to debug your code. Professional developers use special software to handle this entire process. It is much easier and faster. Using such tools and software speeds up the development process.

For students like you, however, it is better to try and debug your code manually – the old-fashioned way. You will have to trace your code line by line and see if the outputs match the expected ones. Manual debugging is time-consuming, but teachers prefer you learn it the hard way before taking the easier route.

#3 Seek Help Online

You have worked out the nature of the errors and also tried debugging them. Sadly, things are not working out for you. And to make matters worse, the assignment deadline is approaching soon. So what do you do now?

You might not have been able to solve the problems, but that does not mean that no one else can either. There are plenty of forums and discussion platforms on the internet that can help you out with your errors. These platforms are widely used by college students to get help with their assignments and seek online homework answers.

Students are often stuck with coding problems. No matter how many hours they spend, they cannot seem to find the solutions to those problems. That is why these online forums and platforms exist. Computer engineering students use these platforms all the time to learn more about coding.

There are experts on the platform who cater to your queries and confusions. They provide step-by-step solutions to your problems. The experts are mostly students like you or even professional programmers. Thanks to the details they provide with their answers, you can have a better understanding of the code itself, and where you went wrong.

These are all things that you need to know for dealing with errors in your code. As you can tell, the approaches are connected. And that is because these errors can be hard to deal with, especially when you have programs that have over a few hundred lines of code. However, as long as you stick to these simple points, getting rid of the errors will not be a problem.
