The graphene and the silver to avoid breaking the Iphone screen

The graphene and the silver to avoid breaking the Iphone screen

Researchers at the University of Sussex combine graphene and silver and promise to generate crystals for the screens of the mobile iPhone more economically, stronger and more sustainable than any current screen in the market.

What would make these crystals in unbreakable for the most common accidents often have smartphones. At the moment, it is only an experiment, but it is especially promising.

Have discovered that a film coated with small silver nanowires exceeds the performance of the film ITO (what you use in current mobile screens) in terms of conductivity, along with other benefits as low power consumption, low temperature operation and durability, it is readily compatible with existing devices.

However, the silver is also a metal expensive and scarce, so while this is an improvement on the current standards, it is the ideal choice for the future by making the manufacture of these screens. And here is where the graphene.

By combining graphene with silver nanoparticles, researchers at the University of Sussex could create a movie that exceeds in performance to existing technologies, but at a fraction of the cost per screen.

Conductivity
What is interesting is that this type of films of graphene and silver can be incorporated into the current iPhone screens, taking into account that the graphene also increases the conductivity, which means that the devices could be more sensitive to touch and use less energy, be more resistant and cheaper than the current ones. The future looks promising.

Facial recognition technology Germany puts to the test

Facial recognition technology Germany puts to the test

More than 200 people registered and stored their photos in the German project, installed at the railway station of Suedkreuz as a means of security and in the anti-terrorist investigations and criminal.

More than 200 people agreed to register their names and store two photographs in the project from the Suedkreuz, where there are security cameras in an entry in one of the escalators

The Train station of Suedkreuz, in Berlin, tested a new face recognition technology to verify the identity of the passengers.

The innovative system installed as a means of security and in the anti-terrorist investigations and criminal, will run for six months in the German station.

Technological progress must not stop in our security services,” said Tuesday the interior minister Thomas de Maiziere said in a statement.

“If the program turns out to be reliable, you should be able to be used for serious crimes and in other places where they have surveillance cameras,” he said.

For his part, the president of the College of Lawyers of Germany, Ulrich Schellenberg, rejected the technological measure and said that “not everything that is feasible from a technological point of view is not necessarily something that we want to have as a society”.

The updates for android

The updates for android

what a user is looking for in a android, is that this is a computer that has a good camera, with a high capacity in its internal memory, and that the cell and its technology is fast, obviously the phone is nice and even, because it does not; that is economic.

Those who know technology, those who understand that, also looking for an android that you upgrade to the latest version of Android.”

Therefore, the brands play with updates, not being clear with consumers. The last to enter Motoerola fu in this controversy, having announced that the Moto G4 and G4 Plus would have Android 8.0 Oreo now seems to have been thrown back and has changed his mind.

At the time of acquiring an android, many have asked that the cell is good, nice and cheap. There are few who request that you upgrade to the latest version of Android

In general, the marks often update some of their models to the next major version of the system, or at least with the most important. However in the mind of the average user are the two years that Google established as logical to update the terminals.

They were quite the brands that joined to that idea, but since then there have been many changes. For example, Motorola went from being an independent company to be part of Google and now to be part of Lenovo.

It is normal that in the different companies have different ways of addressing the issue of the updates. Another issue at the time of update is that a manufacturer you want but you may not be able to do so. This is what happened to Energy Sistem with some of their models. When sold, announced that there would be major upgrade within a few months, but time passed and cannot be launched

Today we will explain how to create a secure password

Today we will explain how to create a secure password

Every precaution is little to prevent us from stealing the account in social networks, email, and other services and applications. At present, the cyber attacks to steal the access data of users are on the rise, so creating a secure password is of vital importance to prevent hackers from accessing our profile.

Many internet users create strong passwords that combine numbers, letters, punctuation marks and other symbols. However, at the time of the truth this type of keys are difficult to remember, among many online accounts that we have today; so users just reusing the same codes.

Avoid including names of people, pets, places where you have lived, sports teams

A few months ago, the National Institute of Standards and Technology of United States, launched a new recommendations to create strong clues based on studies and case studies, and now a study carried out by a team of researchers from different universities in the us provides us with other tips for creating strong passwords according to science.

These scientists have analyzed how different approaches to cracking of passwords to better understand which is the method followed by the attackers to guess the keys. Criminals use computer programs that allow them to make millions or even billions of assumptions in a few hours, which allows them to end descifrandolas.

The process can begin testing with the most popular words in the dictionary, by adding a number or symbol, the first letter capitalized, and so on. Once they have made with the password, attackers can try to reinsert it in order to gain access to other user accounts, as many people reuse their credentials.

Taking this into account, at the time of choosing a key deposit box, users have to focus not on difficult to guess for a human, but it is difficult to understand for a machine. To achieve this, the researchers leave the following recommendations to create a strong password:

Uses keys that contain at least 12 characters and mix two or three different types of the same (lowercase letters, uppercase letters, digits and symbols) in places little predictable (not to the beginning or end).

Avoid including names of people, pets, places where you have lived, sports teams, dates of birth or things that you like. Do not use nor common phrases or lyrics of songs.

Avoid common patterns or easily distinguishable (abc, 123, etc.), or patterns of keyboard (QWERTY, 1qazxsw2, etc.).

A good way to create a secure password is to compose a prayer that nobody has said it before, and use the first or the second letter of each word as your password, mixing it with other types of characters. So you can remember it easily and it will be very difficult to decipher it for a machine.

No reutilices never passwords.
