Tempered glass

Tempered glass: Does it really protect your mobile screen?

We will all agree that the mobile screen is the most delicate component of our devices with a progressive increase in the size of smartphones and their screens. The risk and the fragility of them have also increased. In the development of the new models, the balance leans in favor of design and lightness to the detriment of its hardness and strength.

Most manufacturers incorporate a layer against fractures and scratches in their touch devices. In this field, the reference is Gorilla Glass, of the Corning Company and whose version number 5 doubles in resistance to its previous generation. However, this protection can be effective against scratches, but neither protects against bumps nor does every smartphone carry it.

The screens are not only very prone to breakage and scratches. They are also probably the element of the mobile whose repair is the most expensive. This makes ensuring your phone is increasingly necessary.

So what options do I have to protect my mobile screen?

The first solutions were a plastic sheet. It is an option increasingly discarded by users due to its low durability and low protection against breakage. Some opt for gel protectors of greater protection than plastic sheets. They lose in texture due to their rubbery touch.

It seems to be the ideal solution for the high protection it offers to the screen. Even in direct accidents on the material, such as bumps or falls.

In addition, there are durability and ease of assembly, which allows it to be removed and repositioned without losing adhesion. On the other hand, the option of the plastic sheet requires changing it very frequently and the bubbles make the assembly not so clean.

The sensitivity is one of the most demanding factors by the user. The tempered glass allows you to slide your fingers across the screen while maintaining the same feeling of softness as the naked touch screen.

The tempered glass also stands out for its light transmission capacity and for reducing reflections to the maximum. Some protectors include as an extra functionality an oleo phobic layer to greatly reduce fingerprints on the screen. Most smartphones already include this functionality.

As for the disadvantages of tempered glass, the main drawback is the thickness of the material. It ranges between 0.3 and 0.5 mm. A difference is evident when using the mobile without a case or when you want to press the Home button, which is slightly sunk. Keep reading how to remove screen protector.

Tempered glass installation

If you finally dare to incorporate a tempered glass protector to your iPhone or smartphone, keep in mind the obvious that cheap can be expensive. On the internet, you can find many tempered glass models that they do not meet the estimated durability or fit your phone, despite being indicated for your specific model.

In this regard, during the installation of the tempered glass, we recommend you pay attention to the sensors. Although the design of the protectors already takes into account speakers and front cameras, these are precisely the least delicate. The one that is essential to be discovered is the proximity sensor to avoid problems on the screen.

It is also essential to pay attention to the limits of the crystal. In models with edges, it is important that the protector does not cover them to prevent it from rising. It would be the case of the Samsung Galaxy S6 or iPhone 6 models, among others.

3D Printing

We not yet familiarized ourselves with 3D printing and 3D printing comes the new levitation

Almost every day we hear of a new advance in 3D printing, which has managed to sneak in a lot of disciplines and fields, offering a versatility that puts us in a wide range of possibilities, and with it you can do virtually everything from dentures, parts, to cars, artificial organs, medicines and buildings.

It is a reality that 3D printing is here to stay, and now only need to finish maturing and is available to anyone, but this does not mean that this technology cannot continue to evolve, on the contrary, maturity only means that it is now able to take the next step and that is new 3D printers while floating objects.

Chess, Computers and Humans

At one point in my life I thought it might be a good chess player. In the mid-80 collected and reviewed annotated games by Leontxo Garcia in El País -what big- and even I tried to make my first steps a little more seriously and played a federated year. Enough to realize that it would be better devoted to  write, but I always kept my love of a sport for years to continue sideways.

I did in those legendary duels between Karpov and Kasparov, but also with a nod to the passion that became part of my job: computer science. Expectantly read the news about the fighting between grandmasters and chess computers and cheated me over and over again thinking the man would always be higher than the machine. Absurd, as demonstrate a machine called Deep Blue the 11th of May 1997.

The beginning of the end

Leontxo Garcia wrote it better than anyone again in the country. In ” Man surrenders to the machine ” (curious, lack the tilde in the headline) this journalist recounted how Gari Kasparov ended up leaving the sixth game and losing by 3.5 to 2.5 against Deep Blue after an unexplainable mistake just initiated opening. IBM ride later much a tribute website as another to revisit the games that especially cool because web 1.0 is all.

Kasparov -leed this column his 1996 Time, please-, like the rest of those who attended that, do not believe. It could not have happened. There had to be trick. The legendary grandmaster accused the Deep Blue team of cheating and human intervention in the game Deep Blue, too “creative” at specific moments like that end of the first game (won by Kasparov) in which motion machine 44 he moved his rook for no apparent purpose.

Lenovo Yoga 900 Review

Lenovo Yoga 900 a convertible with many successes

Lenovo seems to have heard the criticisms made, and those that made ​​the users-because the new Lenovo Yoga 900 corrects almost all the flaws of its predecessor and delivers a portable 2 in 1 convertible inheriting the best of Yoga and range and racing is an increasingly bitter struggle in this segment.

A design that highlights the hinge

Let’s start with the bad news. The Yoga 900 is heavier and thicker than its predecessor. It is, however, for very good reasons. Yoga Pro 3 is focused on thinness and weight as fundamental factors, but that was we met a team with a battery below the average and power also room for improvement.

These two factors have been fixed in the new Yoga 900, but this Lenovo engineers have not hesitated to slightly increase both the weight of the device which rises to 1.30 kg from 1.19 anterior- and thickness, reduced from 12.8 mm from Yoga Pro 3 to about 16 mm of this new model.

That makes the team is not exactly a “pen”, but still we have a good bet and a great balance of size, weight and performance. 900 Yoga design is similar to the previous model, with a magnesium alloy as the lead in the upper housing in which, yes, the brand “Yoga” appears more prominent than “Lenovo”. JBL speakers on either side of the team, as we saw offer excellent sound quality even when we put the notebook in tablet mode: a curious detail appears at the bottom.
