At the Facebook F8 Developer Conference, Mark Zuckerberg has given an overview of important issues about the future of Facebook. Specifically, it has announced a camera for an augmented reality platform. In addition, with Facebook Spaces the social network gives the step to virtual reality.

  • Best 360º cameras
  • Better alternatives to Facebook


Snapchat is the Facebook model for augmented reality

Facebook, surprised by the enormous success of Snapchat, has included in the last months, in almost all applications, features similar to those of Snapchat. We can mention for example, Instagram Stories, the new states of WhatsApp or also Facebook Direct. But what are Snapchat features without filters? Little thing.

Camera Effects is the name that Facebook has given to the solution. This platform allows developers to create a frame around an image. However, the development toolset is much more powerful. Because of RA studies (augmented reality), objects can be integrated into videos. This is, therefore, the entry of Facebook into augmented reality.

In the coming years, the augmented reality will be determined by smartphones and their cameras. Smartphones, which may be the most direct access, are not yet technically ready for the market in the near future, as Mark Zuckerberg said during his introduction.

In a broader context, Facebook Camera wants to consolidate itself as an augmented reality platform. Developers will be able to effortlessly create applications that display the content of the camera’s image so that Facebook will take care of the recognition of depth information as well as the location and placement of objects.

What is initially used for the aforementioned Snapchat type filters may be used later for other purposes. Zuckerberg mentioned three pillars that will be basic in augmented reality: displaying information, placing digital objects in the environment, and improving (or replacing) real objects. With the help of the camera of the smartphone, a blank wall could become, for example, an elaborate work of art. Only when this stage is reached, the augmented reality of Facebook will stop following Snapchat’s (more entertainment-oriented) steps.

Facebook Spaces

Although it is clear that Facebook takes the augmented reality very seriously, and spent a lot of time during the presentation, virtual reality was also an important issue during the presentation. Facebook Spaces is the vision of how virtual interactions will take place. Up to three users can stay in a Space and interact with each other through avatars, display photos and, of course, talk to each other. Using a “virtual selfie stick” you can do virtual selfies in Facebook Spaces.

The fundamental element for selfies on Facebook are naturally the avatars. All of them have a similar appearance in mood key, and are based on actual images of the user. Although of course, you can adjust all the parameters to suit each one.

Facebook Spaces is now available as a beta for Oculus Rift. However, Spaces is not limited to this platform, but will also appear in the future in other virtual reality platforms. When this will happen this is something that is not known yet.

Facebook showed an amazing 360-degree camera

With the 360 ​​x24 Surround, Facebook has introduced its own 360-degree camera. With a total of 24 individual cameras, the Surround 360 captures the environment with extremely high quality. The camera is not only able to take simple panoramas, but can create videos with great realism. There is a slightly smaller version of the same that has six cameras.

How To Maintain Good Mental Health?

Taking care of our health is very important; from the health of each of our organs to our emotional health. Mental health is one of the few that are usually taken care of; perhaps it is due to the fact that very seldom we notice of it; however, it is still important. Then, if we notice little of it, how to maintain good mental health? This is simpler than you think and then you will see how.

good mental health


The first thing you need to know is that your mental health depends a lot on your overall health; That is why one of the best ways to care for our mind is to take care of our body in general.

Take care what you eat

This may sound very cliché; but it really is very important to feed yourself well to maintain a healthy mind. You must take care of fats and especially of excessively sugary foods. On the other hand, it incorporates antioxidants such as green tea to your life; you can consume one cup of green tea a day and if possible make it a habit. This will not only help the functioning of your mind, it will also help you lose weight and maintain good health.

Eggs are also very useful; due to its properties you can improve your memory in the long term; avocado on the other hand will help you to improve concentration. Try to eat fish on a regular basis; in this way you can improve aspects like your mood, your energy and even your ability to learn.


This is another aspect that is cliché but which is nevertheless extremely important to our mental health. We must incorporate at least 3 hours of exercise a week into our lives; in this way we will not only be exercising and taking care of our health but also we will be distracting ourselves and moving away problems such as stress, which is one of the main factors that damage our emotional and mental stability.

Another of the things that are recommended to do is that we must always keep positive stimuli around us; These stimuli depend on each individual so you can not recommend one in particular; however, you should know that these stimuli can be from the smallest activities you enjoy to sharing time with your family and friends. You must keep close to you everything you like; make time for yourself and your social circle; listen to the music you like, practice the sport you are passionate about; do the activities that you like, no matter if you are are reading, playing, extreme sports.


Having medium- to long-term goals is an excellent idea; in fact, it should be something almost mandatory for everyone. Among the main benefits that this brings us we can highlight the fact that they keep us focused on a goal; help us plan our lives better and encourage us to learn more and more in order to achieve our goals; as well as being a great way to distract us from the stress of everyday life, since it allows us to think that “everything we do is to achieve a goal.” All of this is important to our mental health.

Internet security depends on seven master keys guarded by 14 people

DDoS attacks on Dyn, a major DNS provider, that for a few hours prevented the world from accessing Twitter, Netflix or Spotify have shown us the importance of DNS in the proper operation of the network. Domain Name System converts addresses like Xataka.com into numeric IP addresses that are understandable by computers, making this technology the Internet’s master key.

A few weeks ago we learned that the keys to accessing the computers that control the DNS were no longer in the hands of the United States, and that they came to be controlled solely and exclusively by ICANN. Therefore ICANN is an organization that protects the Internet, and as if it were a spy movie, it does it with 7 access keys to its main computer that distributes between 14 people. The true guardians of the network of networks.

Every three months since 2010, the guardians of the seven keys gather to perform a kind of security ritual in which they update and verify the keys that allow them to have access to the device that generates all the Internet’s master keys, the keys with which to access the main ICANN database.

And what if someone with bad intentions got access to this ICANN database? Basically it would have the control of the Internet, and that for example could send us to fraudulent addresses when we wrote the URL of a web. We can imagine it as a phishing at epic levels, you can write the address of your bank and take you to a fraudulent account where you steal your credentials.

The Seven Keys Ritual

ICANN has seven physical keys that it distributes to fourteen people, of whom seven are “titular” bearers and the other seven remain as substitutes. These keys give access to safes, within which are the cryptographic cards with which to generate a new SKR (Signed Key Response), which in turn contains new keys that will have to be distributed over the Internet to secure DNS systems.

But the process is not as simple as it seems, since before arriving at the main computer to generate the new SKR it is necessary to pass a whole security ritual. Key holders have to overcome a series of locked doors with access keys and hand scanners until they reach a secured room so that electronic communications can not be made, and in that room is where keys are updated.

The entire event is scripted, and is recorded and audited methodically. It is more the steps that have to follow the participants have been described and distributed among attendees and participants so that anyone can detect that something is not being done as it should. Once the ceremony is over, everything is more casual and Internet owners leave for a restaurant.

In an exercise in transparency, ICANN publishes the scripts for each ceremony and broadcasts it around the world. The next one will take place next October 27 and will be especially relevant, since for the first time will be made the change of the cryptographic master key that ensures that we go to the web that we should when we enter it from the browser.
