How to block calls on both mobile and landline

Published

on

Something that we all suffer almost constantly are calls intended to sell us something, to advertise anything and sometimes they even turn out to be attempts at scams. To solve all these annoying situations, there is no better way than to know how to block calls both on our mobile phone and on the landline.

 

When it comes to blocking calls, we can be specific, that is, suppress the access of numbers or, on the contrary, we can perform this task for all calls that come to our device. This is already everyone’s choice.

Obviously blocking all calls is something more radical, but sometimes we may have no choice, for example, if we want to concentrate on studying and they just get calls.

Everything we do can be reversed, so if we block all calls for a while, once we decide we can receive them again without problems.

Let’s see what are the ways to block calls on the different types of devices that we have today to receive this type of communication.

Block calls from an Android mobile

If we have a mobile phone with the Android operating system, we have ways to ensure that we are not disturbed by calls that we do not want.

These functions, how could it be otherwise, can be activated or deactivated to the taste and needs of each one.

In Android we are presented with several possibilities when it comes to restricting calls, since we can block those that come from unknown numbers , block a specific number or prevent any type of call from reaching our terminal.

We are going to do everything from the Telephone application or from the Agenda in some terminals. Obviously, depending on the phone we have, the situation may vary slightly due to the layer of personalization it has.

  • We open the phone application of the terminal, that is, the one we always press to call.
  • Then we click on the three dots that appear in the upper right corner of our screen to go to Filter rules .
  • Once inside we must click on Call filter rules .Now is where we are going to look at the different options we have to block different types of calls.

    It is a really good thing to be able to choose several forms of blocking, because then each one will use the one that best suits them.

    • Block all calls : in this case, what it does is block any call made to our mobile, except for the numbers that we have on our trust list.
    • Filter unknown numbers : if we activate this filter, all calls whose phone number is unknown will be rejected.
    • Filter private / withheld number : in this case, any number that is private or that does not appear will not be able to call us either.In addition, Android allows us to block calls from specific numbers. For example, if we have a phone number that calls us continuously, making jokes or simply calling us, we will always be able to block it, but for that we need to put it on our Black List or Block List .To use the Block List we must return to the Filter Rules screen and we will see how there is a specific section for this list. If we enter inside, it will indicate the numbers that have been previously blocked , if there are any, in addition to an add button at the bottom.

      If we click on Add we can incorporate different ways to block, such as:

      • Add manually : that is, enter the phone number ourselves.
      • Filter prefix : phones with this prefix will be blocked.
      • Add from contacts : we will add our contacts to the black list.
      • Add from calls : in this case we can block numbers that have called us.
      • Add from messages : if an unwanted number has sent us a message, this is the place to block it.

      Block calls from an iOS mobile

      If we need to block a contact so that it cannot call us again on the iPhone , we will also be able to get it.

      We will add them to a kind of black list and in this way they will not be able to contact us no matter how much they call.

      • Let’s go to the Phone application .
      • At that moment we open the Agenda .
      • Now we go to the contact that we want to stop calling us and click on the information icon .
      • We are scrolling down until we can click on Block this contact .

      Block calls from a landline

      The normal thing to block a number on the landline is to speak with the operator and indicate the precise data for them to block the call option.

      On the other hand, there are also some cases in which we can carry out this task without having to call, but rather, through the app or the client part of the operator’s own website , we have the possibility of placing certain numbers in a list by which they cannot call us.There is also an option that is interesting, but that depends on whether your operator has it active or not. Some time ago it worked in most cases and it is as simple as using the code * 60 and then writing the phone number we want to block, all this with the landline off the hook, of course.

      As we tell you, it may be that it works for you as if it gives you an error. If so, it is best to ask the company that supplies you with the fixed line what code or systems they use.

      Block in calling apps

      WhatsApp

      As you well know, WhatsApp is also used to make calls and as it is the most used messaging app in the world, it is convenient to know how to ensure that certain numbers cannot communicate with us through this application.

      To achieve this we only need to perform the following steps:

      • We open a WhatsApp conversation that we have had with the contact we want to block .
      • We click on the three points in the upper right corner and then we go to More .
      • Now we select Block .
      • At that time we will see that we can Block, Cancel or Report and Block . Now everyone who chooses the one they want, but in principle blocking would be worth it.

        Telegram

        The other great option when it comes to calls by app is Telegram , WhatsApp’s most direct competition.

        In this app we can also block a contact and we are going to do it as follows:

        • We open Telegram.
        • We touch on the three lines in the upper left corner and go to Settings .
        • We open Privacy and security and then Calls .
        • Within calls we have several options such as choosing who can call you (everyone, My contacts or Nobody), adding exceptions to the previous rule or with whom we can use Peer-to-peer.
        This is the way in which we can block calls in the different types of systems that we have to receive them.

        As you have seen on all devices we can assign a lock to someone so that they can no longer communicate with us.

Virtual reality to better manage stress

Published

on

A laboratory of a Valencian university develops with several companies a neuroscience and ‘gamification’ project to monitor how people face challenges and complicated situations

Leisure and video games are two closely linked concepts, although in recent months one more element has been added to this equation: neuroscience. This field of science deals with the study of the nervous system, which is made up of the brain, spinal cord, and networks of sensory or motor nerve cells – called neurons – throughout the body. But what do video games have to do with the nervous system? The answer would be Atemin.

This project, financed with more than 650,000 euros by the Ministry of Science and Innovation (MICINN), was born within the Polytechnic University of Valencia (UPV). It is the result of the work of LabLENI, the UPV’s Immersive Neurotechnologies research laboratory, together with the collaboration of the company Martin Brainon, specialized in behavioral sciences and risk management, and the firm Quatechnion, which develops technology-based solutions.

This is where ‘gamification’, the technique that combines learning with leisure to improve skills, joins neuroscience to see how a person reacts to certain stimuli or situations. Thanks to virtual reality, Atemin guarantees behaviors and brain responses similar to those experienced in real situations.

During the experience carried out by this project, the user is monitored by recording all their behaviors and interactions. The movement of your gaze and its physiological response are also analyzed, thanks to a sensor that measures the galvanic rate of the skin that indicates its level of activation or stress.

Users interact with the virtual environment, which is presented in game format, while all their decision processes are evaluated. “Atemin analyzes more than 200 data per second and its predictive algorithm has achieved an accuracy of more than 70% in the dimensions that are evaluated”, point out the people in charge of the project.

Based on the behaviors and reactions of the users during the experience, the Atemin system can process all this information and predict its results with high precision in terms of the different dimensions that make up risk decision-making.

Its primary objective is to help companies in risk management, focusing on the human component and, unlike traditional tests, without biases of age, gender or job position. “We make more than a million decisions a day, so investing in improving the capacity of this decision making has a direct impact on the security, profitability and productivity of companies and more in the current context, of uncertainty and change constant ”, argue Olga Pérez and Noemi Álvarez, founding partners and CEO of Martin Brainon.

Seven dimensions

With the information collected, Atemin is able to obtain a decision-making profile and train up to seven dimensions that directly influence this process: emotional self-regulation, attention, control, persistence, impulsivity, aversion towards uncertainty and mental flexibility.

Once the profiling is done, the platform allows training skills through virtual reality. The system provides tailored instruction for each person, where, on the one hand, the two dimensions that have obtained the lowest value are exercised and, on the other, the dimension with the best results to take it to excellence. “After training, seven out of ten people improve their attention and mental flexibility,” highlight those responsible for the project. “And 100% improve in at least two dimensions in their decision making,” they add.

The virtual reality on which Atemin is based has been designed to be applied in any business sector. This approach allows us to contemplate physical, strategic or social risk, also facilitating a personal growth of the participants beyond their working life.

Hacker who stole 600 million in cryptocurrencies did it ‘for fun’, charges a reward for discovering the flaw

Published

Unexpected turn of events in the biggest crypto theft in history. Now the hacker or hackers say that they had never intended to steal them …

 

It appears that the biggest cryptocurrency theft in history will have a happy ending, although some experts have doubts that that ending is the true one.

On August 11, cybercriminals stole $ 600 million in cryptocurrency from Poly Network , a decentralized finance provider that allows users to transfer tokens between networks. This is the biggest crypto theft in history .

According to Reuters , he or the hackers took advantage of a vulnerability in the system that changes tokens from one blockchain to another, to steal them.

Stealing cryptocurrencies from within the blockchain is almost impossible , because thousands of computers would have to be hacked at the same time.

This is why hackers steal the individual wallets that contain them, or exploit bugs in the processes of transferring cryptocurrencies from one site to another.

All token movement operations (currency units) are recorded. But who owns them is an anonymous piece of information , almost impossible to trace. It is one of the strengths of cryptocurrencies, and also the biggest problem if they are stolen.

This murky matter has taken an unexpected turn, after Poly Network announced that they have contacted the hacker Mr. White Hat (in the jargon, a white hat hacker is an ethical hacker), who has assured them that the hack was ” for fun “, and that they never intended to keep cryptocurrencies.

Poly Network has offered him a reward of $ 500,000 for revealing the security flaw that allowed the theft, and in return they will return all the money . They have already returned more than $ 340 million.

A happy ending for the speculators … sorry, investors who own those cryptocurrencies, although the story is not so clear.

Some experts think that laundering those 600 million in cryptocurrencies is very complicated , so perhaps the hackers have thought better of it and have decided to negotiate a payment to return the cryptocurrencies , making it up as a reward for discovering a security flaw, to avoid the repercussions legal theft.

We do not know what the truth is, but in any case it is a happy ending for those involved who were afraid of losing their money.
