Drones change our lives. Or better?

Is it a bird? Or maybe the plane? No, it is an unmanned aircraft, piloted remotely or autonomously, known as a dron.

Drones are everywhere and they can do everything – they save lives, they deliver pizza. There are more and more people around us, but with the increasing popularity of drones, there are completely new problems with their ubiquity.

In April, during US President Barack Obama’s visit to the United Kingdom, drones were considered so serious that the security services banned them from using in some districts of London and Windsor.

Speaking in May on the occasion of the inauguration of the new parliamentary year, the British Queen announced the introduction of legislation regulating the use of drones. The new law will guarantee the UK “a leader in technological security in the auto- matic vehicle industry such as drones and spaceplants.”

Although they are considered a modern invention, unmanned equipment was used in the 1930s as a flying target for training British anti-aircraft squadrons.

Today drones are no longer just military domain – they have found many civil uses, smaller versions are eagerly used by companies and private users. They definitely make life easier for us and they bring in a lot of good things but they also have their bad side.

In the gallery we present specific examples of good, bad and “lazing” dron applications

Drones can change the world for the better. In the UK, emergency services use them to rescue people in distress, and the defense industry is investigating how they can increase our safety. Throughout the world, wildlife defenders use drones to monitor animals and detect potential dangers.

Unfortunately, drones also change the world for the worse. Although they are used to defend against security threats, these devices may also be deadly. Some complain that their drones are spying and peeping. But, as others have noted, does it matter if there is nothing wrong with it?

Drones do both good and bad. They definitely make our lives easier or, depending on their point of view, they make us even more lazy.

What is dron?

Dron is simply an unmanned aircraft. The solution invented the army. The first radio-controlled reusable flying machines appeared in the 1930s – devices used to train antiaircraft units are considered the prototype of models currently used around the world. In the 60s during the Vietnam War, military drones equipped with cameras were used in scouting missions. The latest military drones carry bombs and missiles.

Today dron can serve anyone, not just the army. Smaller, civilian versions have found use in many different industries, as well as entertainment.

Can anyone handle a drona?

The short answer is yes. Drones are becoming more advanced, and at the same time getting cheaper – today everyone can buy a simple dron.

How many drones are in the air?

In the United Kingdom, more than 300 public companies and institutions have permission to use drones. Most drones belong to film, photographic and label companies such …

Washer Revolution is a new way of taking care of hygiene

In many countries, water is a scarce commodity, and even such a desirable activity as washing hands after using the toilet leads to excessive consumption. The inventor of Donal Vitez, however, has developed yet another version of the device designed for washing and drying hands, which consume very little water.

His previous project was called Robo-Washer and consisted of a tall wooden chest and a stainless steel bowl on top of it. The hands put on her were sprayed on all sides with soapy water under high pressure, and then the drying process began. The first model used only a mug of water for one use, which then flowed into the sewage.

The second generation of hardware is called Robo-Washer Revolution, which is much more advanced. This time the user’s hands are no longer sprayed with soap but with antibacterial water. After each use, the device is filtered and disinfected by the same water, which, after sterilization, is used to clean the palm of the next user.

Vitez claims that his equipment provides hygiene at the hospital level, while consuming very little water. The inventor also points out that the technology he develops can be used for many other tasks, such as showers, dishwashers,…

Google streamlines voice searches

Most of us, seeking information through Google search, do it in the traditional way, using the keyboard. You can also use voice commands, and that’s exactly what Google has done very well lately, speeding up performance and correcting commands.

The voice search system works a little differently than Siri. For better functioning, it analyzes in real time every word spoken by the user, writing them on the screen. This allows you to see if it is well understood and you can make some further changes.

Google also claims that the voice search feature can remove the background noises captured by the microphone so that it does not interfere with the reception of commands spoken by the user. This provides a better model of acoustic neural network using temporal linkage classification and discriminative sequencing techniques.

It sounds pretty complicated, but it is important that, thanks to applied solutions, the function works much better. And for more details about the changes you’ve made, you’ll find it on Google.…

A new autonomous vehicle communication system

The Delphi American company is also working on autonomous vehicle technologies. Last year showed a prototype that traveled alone from San Francisco to New York, and now shows the next phase of this technology, the V2E (vehicle-to-everything) system, which enables vehicle communication with the environment.

Autonomous vehicle functionality does not end with the recognition of signs and other objects, nor the use of accurate road infrastructure maps that provide the ability to move independently. These vehicles must be equipped with many additional systems to improve their functionality. Delphi has recently introduced this technology, which is launching another phase in the design of autonomous systems.

Its latest concept is a vehicle-to-everything (V2E) system that enables vehicle communication with the environment. Appropriate technological solutions allow the vehicle to communicate with the street, traffic signs, traffic lights, other road users, and even pedestrians. And all this is to improve the performance of such cars and improve safety. According to Jeff Owens, head of technology at Delpi, V2E will bring active safety and self-driving technology to a whole new level.

Combining advanced software, a wide range of sensors built into the vehicle, and a platform for full connectivity to the environment will provide passengers with much greater safety. If, for example, the preceding vehicle will have to brake in an emergency, it immediately transmits the appropriate signal to the other automaker, which will prevent them from falling over. By communicating with special chips on smartphones, the vehicle will be able to easily detect pedestrians who have broken into the roadway and take appropriate preventive measures to prevent collisions.

The new solution also utilizes the Dedicated Short Range Communications (DSRC) technology, which provides communication with traffic lights and informs the vehicle of upcoming light changes. This will allow you to adjust the vehicle speed so that you do not have to stop on the red.

Blind Corners technology will be useful in intersections where visibility is limited and it is difficult to see the approaching vehicle. Also useful is the Ride Sharing system, which will notify family and friends that we are going for shopping, for example, so they can take us if they want to.…

Artificial leather with real hair

Artificial leather covering all kinds of prostheses, until now, looked unnatural. But Japanese scientists have managed to create a skin prototype that looks almost as real as the real one. Not only does it grow on her hair, but she can sweat as well as human.

The development of bioproteins and robots has made it necessary to start working on more realistic artificial skin to cover the prosthetics and mechanical limbs of humanoid robots that will inevitably appear in the future.

So far used artificial leather is made of a suitably-colored latex so it does not look too natural. But Japanese researchers have managed to create a completely new type of cultured skin, which not only grows Italian but also can sweat. Scientists have used the cells extracted from the gums of the mice for this purpose and then converted them into stem cells.

Then they implanted it to mice without the immune system. As a result of these experiments, we managed to get a fully functional connection with natural tissue, thanks to which cultured skin, not only follicles, but also sweat glands and sebaceous glands.

Naturally developed by technicians is still far from practical applications. Specialists suggest that for clinical trials done on humans, we will have to wait for at least 10 years.…

New record speed data transfer

The Internet offers us more and more opportunities that require faster connections. Those that we have now are still sufficient, but when 4K hybrid hybrid technology becomes available, they will become too slow, so researchers are working on even faster connections. And they just managed to break another record speed of data transfer.

The joint efforts of scientists from Eindhoven University of Technology and the University of Central Florida have allowed a new record of 1 km of optical fiber. They managed to achieve a transfer rate of 255 terabits per second, equivalent to 32 terabytes per second.

You probably can not imagine such speed. It is enough to send 1 TB of data in 31 milliseconds. In other words, you can upload over 200 Blu-ray movies in a second.

So far, the highest single-fiber optical data transfer rate used in commercial operations was only 100 Gbps, which is about 2550 times slower.

Of course, single fiber does not mean one thin Italian fiber. The researchers used a multi-core fiber, ie one that consists of seven individual hexagon cores.…

Windows 8. 6 months after the premiere. How are new windows handled?

It has just been exactly half a year since the launch of Windows 8 for sale. New Microsoft windows do not do very well, though.

Windows 8 officially hit the market October 26, so half a year ago. Microsoft has taken water for several months and is silent about the results of the system’s sales. It is quite possible that the official data will come to us until June, when another conference in the Build series will take place. Keynotes on this event are always covered by sales results and other statistics. Probably this will also be the case … how much Microsoft will boast.

While the Redmond giant is silent, it’s time to sum up the first half year of the market presence. Unfortunately, it is not good.

The information disclosed by StatCounter shows that Windows 8 currently has a 4.69% share of the operating system market. This is worse than the one that can boast of Windows Vista (6.06%) and OS X family (7.11%). Of course, there is a “seventh” leader who can boast almost 54%. Windows XP in turn occupies 27.7% of all computer hardware (so on the margins, it is worth mentioning that currently about 45% of companies use this system. A lot when we consider the placement of this version of the window and the fact that in less than a year support ends.

So how exactly license Windows 8 so far sold? The latest information comes from January this year (when Tami Reller praised 60 million sold windows), so they are a bit outdated. However, given that there are around 2 billion computers in the world, and a share of Windows 8 is less than 5%, you can be tempted to say that Microsoft has so far failed to sell up to 100 million copies.…

Toshiba presented a television that you will take with you to the parcel

The family of REGZA Toshiba televisions has expanded its 19-inch 19P2 model. The LCD TV has a resolution of 1366 x 768 pixels, LED backlit matrix and 1000: 1 contrast ratio. In addition, the device is equipped with a digital DVBT tuner, one HDMI port and one D4 plug (Japanese standard).

The specifications certainly do not impress, and the TV would be hard to say something interesting, if not for the fact that it was built into … replaceable battery. As the manufacturer assures, a small Regza can work on such power for about 5 hours. And since the batteries are removable, you can buy a few “in stock” – the price of one is less than $ 90.…

The next smartphone makers are announcing their own chips

It looks like the future of Qualcomma and MediaTek, as the largest mobile processor vendors, is getting darker. The number of customers is rapidly shrinking as more and more companies start designing their own systems.

The processor market for smartphones is very large and therefore extremely lucrative. There are several hundred million smartphones in the world, and most of them have processors mainly from MediaTek and Qualcomma. Soon, however, both companies will have to count on significant profit reductions as more manufacturers are planning to produce their own processors.

As the first to go in this direction Samsung with Exynos family of processors, and then the same did Huawei, designing a Kirin. This approach has several advantages, as the smartphone manufacturer then has better control over the device’s performance and can better match the processor to the other components.

Soon, the number of companies that will produce their own CPUs will soon increase, as such plans have just announced new companies. One of them is ZTE, which has just received $ 73.8 million in a Chinese investment fund to accelerate the development of a new processor. Huawei also intends to increase production of its chips by resigning from MediaTek and Qualcomm.

Xiaomi has partnered with Leadcore Technology to jointly develop a new processor for its products, which will be available next year.

If smartphone manufacturers start designing their own chips, then customers will get better and more efficient devices, and that’s good news.…

10 useful google search engine features you may not know about

Google’s search engine has revolutionized the internet and remains today the leader in its category. But beyond the search alone, there are some very useful features you may not have known.

There is nothing to cheat that “Google Uncle” counts on us to use his services as often as possible, so he cares to meet our needs even before we even think of ourselves.

Therefore, you probably already know some of these features, and you have found them without seeking a solution to the specific problem or information you need. Maybe you can find in this list built into the search engine tools, which you did not realize exist?

Currency converter

Thanks to the internet, much more stuff and services are bought abroad. With fast-paced courses, this quick information is very important. Better yet, when we can immediately see how much it will cost us a specific purchase in dollars, euros or pounds.

There is nothing simpler to find with Google, even if you know the international currency abbreviations.

Unit converter

Some problems may also be caused by differences in units of measure, weight or speed. Mile for miles? Pounds per kilogram? No problem.


The weather is good for us, even if the verifiability of their forecasts is different, it is always worth checking before leaving home, whether the situation we see outside the window will not change in the near hours. Or maybe you just want to see how the situation looks in another part of the world?

East and sunset

In winter you are wondering which time will finally be bright, and in the summer or if you can still shoot without a flashlight? Enter east or sunset …

Local time

Time zones in specific locations do not always coincide with the geographical location, including summer time, from which some countries have already resigned – we are not always sure which time is the person we are calling to travel to. , Or where there is an event that the broadcast we want to watch online. But with Google this is no problem.


It is easy to find dictionaries in the Internet. The built-in Google search engine allows for quick translation of words and phrases without having to go to other web pages. Languages ​​from Afrikaans in Zulu with the option of translating speech (words spoken into the microphone) and listening to the translated text.


Times of glory the physical calculators have already gone: This is one of the default programs on most fixed or mobile systems. If, however, we need to calculate something quickly while browsing the web, such a function can satisfy the search engine window. Once you’ve entered an action, we’ll see the result on your default Google calculator.

Function graphs

We already know that the search engine will perform even the most complex mathematical operations. What if we would like to see a visual presentation of the equation? It’s also no problem.


Time for something more “alive”: you knew …
