A photo recovery software that is worth your time

Today I am writing about a topic that should be important for most you: data recovery. During my lifetime, I have encountered at least 5 situations when I thought that all the data that was stored on my hard-disk or memory card was lost forever. I must admit that with the help of some friends, most the time I managed to recover that lost data. But the process was far from easy, since they have used all kind of command lines, apps and operating...

New vulnerabilities discovered in 4G and 5G networks. All devices can be accessed by hackers

Syed Rafiul Hussain, Nighui Li and Elisa Bertino, researchers at Purdue University alongside Mitzu Echeverria and Omar Chowdhuri of the University of Iowa will publish a study that demonstrates new vulnerabilities found in 4G and 5G networks. The paper was presented for the first time in the symposium on "Network and Distributed System Security", which is held today in San Diego, California. In short, 4G and 5G networks can be exploited to...

Oh, boy. I made a mistake! This is how it begins. You know what I am talking about. It's that moment when you realize that you have deleted important files on your laptop by mistake. Few seconds later, the panic gets into your mind and you probably think that there is nothing you can do about it, especially because you've already emptied the trash. Well, if you've ever found yourself in this situation and you stumbled upon this...

IBM’s historic launch: The first quantum computer has been officially presented and looks great

IBM introduced IBM Q System One at CES 2019. It is the first quantum computer that is ready for mass distribution, . Before you get ready to ask how well Read Dead Redemption 2 and FIFA 19 will play on this computer, there are a few things about this computer that you should know. According to ZDNet, IBM likes to always be the first to release something new. That's why ZDNet journalists note that this quantum computer is...

A new artificial brain for autonomous robots was created by an important company

NVIDIA had a plan to use the power of accelerating solutions provided by artificial intelligence to develop a synthetic brain. It would be easily programmable and powerful enough to control robots. A large automation area has led to the launch of a commercial product. Available at prices starting at $1299, the new Jetson AGX Xavier can become the brain of a new generation of robots and other intelligent machines. It is delivered in batches of at...

How to Recover files deleted with Empty Recycle Bin function

Most operating systems have a recycle bin that acts as a fail safe. It gathers all the deleted files and keeps them there until you decide what to do next. You can restore some of the files in the recycle bin (trash) or you can empty the Recycle Bin. Now, here comes the funny part. Once you decide to empty the Recycle Bin (trash), those files are deleted for good and you will not be able to recover them easily. Sure, you might say that no one...

The shortest fly from London to New York will take only two hours

Although commercial planes have shorten the time it takes to go from one place to another, there are people that are still complaining about long flight hours. Boeing could have a solution to the problem. It has introduced details of a new type of Hypersonic Airplane that will be able to cross the distance between New York to London in just 2 hours. The first ultra-fast Mach 5 flight could take place in ten years from now, 2028. The Hypersonic...

The fastest supercomputer in the world is a million times more powerful than a laptop

Researchers at the Oak Ridge National Laboratory (ORNL) unveiled the fastest supercomputer in the world. The machine was named Summit and it has the size of two tennis courts, consisting of 4,608 servers. Thus, the supercomputer can achieve a performance of 200 petaflops. In other words, it can achieve about 200 quadrillion calculations per second. Summit has officially surpassed the previous record, set by China's Sunway TaihuLight...

Research: An efficient lithium-iron oxide battery was developed

A team of researchers at Northwestern University has created a lithium-iron oxide battery that has the potential to power cars and phones more hours than previous batteries. Moreover, it is cheap and rechargeable. Christopher Wolverton and his team of researchers at Northwestern University have worked in collaboration with a team of researchers at the Argonne National Laboratory. They have created a new battery that, at least in theory, should...

Are autonomous cars safe? A new car model illustrates security breaches

A new car model illustrates the security breaches of autonomous vehicles. How safe are they after all? Every new generation of cars comes with technologies that expose new safety risks. But in the case of autonomous cars there is no precedent, the dangers being little studied, experts suggest in a new study. Imagine three different scenarios: The stand-alone car could take you to an isolated place, although the destination is your home. You...

How does the quantum computer work?

Ever since the first recorded computer was invented, back in 1613, humans are trying to perfect it and to make it as faster as possible. These days, our computers have reached the computational power of computers that were presented in Sci-Fi movies back in the '50s and the '60s. A question remains though: Will we ever have the processing power we want? If Moore's law continues to be valid in the next period, by 2030 we will have microchip...

DYI: How to build a photovoltaic solar panel system

In this article, I will share the basic stuff you need to know in order to build a photovoltaic solar panel system in your own home. As you probably know by now, with the fall of photovoltaic cells price, the demand for solar panels is getting higher. By building a photovoltaic solar panel system, you will save a lot of money on the long run, but you will also help the environment by not using fossil based energy. As the solar panel market goes...
