In 20 hours they have reached 596 million euros. It is the "most reliable and innovative" cryptocurrency and a "liberating mechanism". The Government of Venezuela has launched on Tuesday the presale of the petro, the cryptocurrency backed by the natural wealth of the country, as confirmed by the Executive Vice President of the Republic, Tareck El Aissami. In his speech, the vice president of Venezuela stressed that the petro emerges as the most reliable and innovative cryptocurrency, noting that "it is an instrument of the 21st century" and encouraging young people in the country to be "the vanguard of electronic mining". "Today the Venezuelan petro presale is formally and officially launched, and Venezuela is at the forefront of future times," said El Aissami. "It is a novel initiative of the Bolivarian Government, a liberating mechanism," he added. Last week, the Venezuelan president, Nicolás Maduro, signed the so-called 'white book' of the petro, in which the characteristics and functioning of the new Venezuelan digital currency are established. According to this 'white paper', in February would sell 38.4% of all petros that will go into circulation, the equivalent of 2,300 million dollars, and a month later 44%, about 2,700 million dollars. The rest would be in the hands of the Government and its group of advisers, VIBE. After the launch, Maduro has announced that the presale of the petro has reached 596 million euros since its activation, midnight Monday, until 8:00 pm local time on Tuesday (00:00 GMT).

Phishing continues to be one of the main security threats and cybercriminals are constantly looking for new formulas to trick users, with the aim of stealing their personal and financial data, installing malware or other malicious purposes. The use of false domain names similar to legitimate ones is a strategy that criminals often use in their phishing campaigns. This is the case of typosquatting, a technique that takes advantage of typographical errors of victims, or combosquatting, which is based on the use of domain names similar to those of legitimate pages so that victims do not realize they are accessing to a fake site. Another dangerous strategy we have seen in recent months is based on the replacement of certain characters by Unicode signs that are visually almost identical, which allows attackers to register false domains that can deceive anyone, as we could see in the case of this trap that uses Cyrillic characters to impersonate legitimate addresses of banks and companies. The new technique that criminals are using follows this line, but in this case it is based on the use of an almost imperceptible lower diacritic point that appears under vowels and consonants, both uppercase and lowercase. What the attackers do is register false domains using these characters, so that at first glance they are practically identical to the ones they want to impersonate. It's the strategy they've used, for example, to create a fake page that mimics the po[CENSORED]r Exchange Binance. This has been reported by users on Reddit, who warn that a phishing campaign is circulating that replaces the "n" of the legitimate domain by "ṇ" with a lower diacritic point. To avoid being a victim of such attacks, check carefully the addresses you visit, especially if they have arrived by email, and try to write the URL by hand without mistakes or typographical errors.

A team of engineers from the University of Utah (United States) has designed a system that allows to carry out an accurate location without GPS. It is a set of sensors and circuits mounted on a boot, and the platform has the ability to determine the position of the user with an accuracy of five meters both indoors and outdoors. Surely you know how the global positioning system works. It is based on the mathematical principle of trilateration, so to determine the location of the user it is necessary to use a GPS receiver and be in the line of sight of at least three of the 24 satellites in orbit that are used to determine the positions. Although GPS are very useful and are becoming more accurate, they have the problem that they do not work properly indoors. The prototype that these researchers have created solves this difficulty, since their platform is able to determine the location without using the satellites. It consists of a boot that mounts an inertial measurement unit or IMU by its acronym in English, which is an electronic device that contains a gyroscope, a magnetometer and an accelerometer to measure and report on speed, orientation and gravitational forces. In the template of the boot there is a flexible MEMS pressure sensor that registers each footprint, and on the side it incorporates a circuit board that connects to a laptop computer stored in a backpack. In the tests, the prototype was able to track the user's position for about three kilometers with a maximum error of 5.5 meters. "Performance is comparable to GPS, but it works indoors," says Qingbo Guo, one of the team members. The system is an initial prototype and there is still a lot of work ahead, but its developers believe that its navigation system without GPS can be very useful in many applications, especially in rescue and rescue work or video games of virtual or augmented reality , among other examples.

The arming of teachers is not a new idea and is certainly controversial. US President Donald Trump on Wednesday expressed his support for the possibility of training firearms in some teachers and allowing them to be carried inside schools as a way to deter possible attacks against teachers. schools. "That's called hidden behavior, so a teacher would carry a concealed handgun with them, they would go to receive special training and they would be there," Trump said during a White House meeting with victims of the shooting at Marjory Stoneman Douglas Middle School, the week last in Parkland (Florida) and in which 17 people lost their lives. Angry students, the new and challenging voice in the debate on weapons in the United States "I do not know how I will return to this school": the trauma of the students who lived through the massacre in Parkland, Florida "If you had expert masters in firearms they could very well end the attack quickly," he added. When launching the idea, Trump asked the attendees to the meeting to say if they agreed with their proposal. There were more rejections than supports. "Teachers have more than enough responsibilities right now to carry the enormous responsibility of having to use lethal force to end a life," said Mark Barden, whose son died in 2012 at the Sandy Hook Elementary School massacre. in Connecticut. The proposal to arm teachers and other school employees has long been endorsed by the National Rifle Association (NRA), considered to be the most important lobbying group in the sector in the United States. The president explained that this measure would put an end to the limitations that prevent the carrying of weapons within schools, something that - from his point of view - makes them more attractive as the target of the aggressors. "For a maniac, weapons-free zones mean: let's go in and attack," he added. Trump also promised to toughen the background checks required for the purchase of weapons. "We are going to make very strong background checks, (to put) a lot of emphasis on the mental health of the people and we are going to do many other things," he said, announcing that next week he will meet with governors from most of the states. to discuss about every aspect of school safety. "We are going to take the best ideas, the most important ones ... and we are going to execute them, it will not be (only) to speak as it has been in the past," he said. "I'm mad" During the meeting, Trump listened to several of the survivors of the Parkland attack, as well as the relatives of some of the victims. Andrew Pollack, whose daughter Meadow was among the 17 dead at the school located in South Florida, expressed anger at the president. "We are here because my daughter has no voice, she was murdered last week and she was taken from us, she received nine shots, we, as a country, we failed our children," he said. "I'm mad," he added. Gun control or a mental health problem? United States is divided after the shooting perpetrated by Nikolas Cruz at a high school in Florida Sam Zeif, an 18-year-old student who survived the Parkland attack, questioned the ease with which the sale of weapons in the United States is allowed. "I do not understand why I can go to a store and buy a weapon of war, an AR (the type of semiautomatic rifle used by Nikolas Cruz, the attacker of the Parkland school)," he said sobbing after telling how he was sending text messages to his family during the shooting. "Let's not allow this to happen again, please, please," he added. While some survivors of the Parkland massacre flocked to the White House on Wednesday, others moved to Tallahassee - the capital of Florida - to demand state legislators to restrict sales of assault rifles. There were also protests in several cities in the United States, including Washington D.C., Chicago and Pittsburgh.

Welcome Back

If your phone runs slower and slower, this problem can be due to many factors. One of the influencing factors is the available storage space and the type of storage space, since not all memory formats are equally fast. That's why it's good news that UFS 3.0 is just around the corner, because it promises a speed of reading and writing up to twice as fast. The impact on the performance of mobile phones and other types of devices can be very important, since it will make it easier to move files and also the functioning of the operating system, sometimes burdened by the slowness and limitations when reading stored data. in the ROM. When it comes to assessing the speed and performance of a mobile, it has nothing to do with the processor or RAM. Obviously being able to run more processes at once and heavier will make a phone work faster, but you can rewrite and read the data also has a lot to do. The UFS 3.0 memory format promises up to 2.4 Gbps of mobile transfer. In addition to providing more speed to the operation of the memory, UFS 3.0 will do it consuming less energy. This is very good to optimize the battery life of mobile phones, cameras and tablets to the maximum using the double channel to write and read memory information simultaneously. This new standard also affects UFSHCI, although it will gradually spread, especially as devices incompatible with the new features of UFS 3.0 are becoming obsolete to be replaced by more modern ones, something that will inevitably happen over time.

Little by little Google's Artificial Intelligence learns new things, tasks to be carried out almost completely without humans. He already knows how to play table games and some online video games, and now he wants to go straight to completing the most po[CENSORED]r encyclopedia in the world: Wikipedia. The Google AI already knows how to write entries in Wikipedia, although it does not do it completely autonomously. The method is as follows: take the first ten pages that appear on Google on a specific topic, process them based on the machine learning and then write what you think is important. The Wikipedia entries generated by Artificial Intelligence are not even comparable to those written by people of flesh and blood, but at least they are legible. It is clear that the Google AI is still at an early stage of its development, although the fact that with very little has been able to assimilate thousands of words in a matter of minutes gives us an idea of where you can go shortly . Unlike humans, who need years of study in a subject to generate content about it, Artificial Intelligence could - not yet, but may someday yes - study and generate material in a matter of minutes on topics that are incomprehensible for a human. This perhaps implies that certain jobs are in immediate danger of disappearing, and would not be the first ones threatened by robotization, which will go beyond merely manual or low-skilled jobs. The limitations of this technology are currently more than evident: it can only generate information from existing information. It is not able to create original Wikipedia entries, but it processes text that already exists and condenses it into a page as brief as possible about a person or topic. Below we attach an image comparing the Wikipedia entry made by the Google AI (left) with the one created by collaborators of this online encyclopedia. It's from The Register and it's in English, but as you can see, at least DeepMind knows how to express himself with complex sentences, even though he makes many mistakes. These entries have not been published as they are a mere test of the ability of Google software.

A new earthquake measuring 6 on the Richter scale has shaken the western coast of Mexico today, February 19. According to the National Seismological Service of Mexico, the earthquake occurred at 00:56 hours (local time) in the state of Oaxaca, 36 km from San Miguel Panixtlahuaca, and near Puerto Escondido. In addition, the quake has had the hypocenter at 10 km depth and has been felt even in the Mexican capital, 320 km away. As reported by Luis Felipe Puente, national coordinator of Civil Protection of the Ministry of the Interior, there has been no record of damages or victims. Mexican President Enrique Peña Nieto has indicated on Twitter that Civil Protection "activated its protocols and is in contact with local authorities."

The choice of storage for your computer is one of the most important factors in determining its performance. Depending on the type of hard drives you choose for your PC, or how you connect them, their performance can vary substantially: Do you know what is a RAID disk and how can you help improve the performance of your computer? We tell you The easiest way to connect a new disk to your PC would be to simply connect it to your computer's motherboard and use it as a stand-alone unit. But, did you know that you can improve the performance of your computer and the security of your data by configuring a RAID storage system on your computer? This RAID system consists of grouping a series of hard disks so that they work together and sharing the common storage space to avoid losing your data if one of the disks fails or improves the speed of reading and writing of the disks. Do you want to discover what is a RAID? Here we tell you all the details you need to know to create yours. What is RAID? A RAID (from the English Redundant Array of Independent Disks) is a set of hard disks that combine to form an array of disks that the operating system recognizes as a single logical unit in which the data is stored in a distributed and redundant way, improving So the security of the data you store in them. One of the most common uses for RAID systems are servers, where this combination of disks is used to avoid the loss of stored data. That way, even if one of the disks fails, the information is not lost and can be replaced to continue storing. Another common use of RAID configurations is found in NAS storage systems. How many types of RAID are there? There are different types of RAID arrays with which to obtain different results in terms of security or increased performance. Each of these types of RAID has been developed to distribute the data differently among all the disks that make up the matrix, and thus optimize the security or speed of reading and writing the set of disks that form it. There are more than 15 different RAID types or variations of them, so we are not going to list them all, since in some cases there are slight evolutions of other types of RAID and their use is very specific or minority, limited in many cases for use Exclusive in business servers. These are some of the most used types of RAID: RAID 0 The RAID 0 is one of the types of RAID most known among users since it provides a higher speed of reading and writing, managing to accelerate the overall performance of the computer. This type of RAID is especially po[CENSORED]r among gamers, providing extra performance to any team and reducing the loading time of game levels The matrix in RAID 0 distributes the data equally among the units that form it, without including redundancy. This equitable distribution of the data means that the access speed is practically doubled, given that each disk simultaneously transmits the data in parallel, exponentially increasing its performance in relation to the number of units that make up the matrix. Unlike most RAID configurations, RAID 0 does not provide fault tolerance, so if one of the disks that make it suffers a failure, all data will be lost without an option to recover it unless you have a copy of it. security. To form a RAID 0 matrix, you need a minimum of two disks, which can be of different capacities, although the capacity of the smallest disk will be taken as reference when forming the matrix. Therefore, if you connect a 2 TB disk with a 500 GB disk, the result of RAID 0 will be a 1 TB unit (500 GB x 2). RAID 1 The configuration in RAID 1 or mirror, is also very po[CENSORED]r among users. This mode allows greater tolerance to mechanical failures, giving greater reliability to domestic data storage systems. Repair your damaged hard drive with bad sectors This type of RAID doubles the contents of a disk in the rest of the disks that make up the matrix. In this way, fault tolerance is increased exponentially. In other words, if one of the discs is damaged, having duplicated the data, the information remains intact on the disk that still works. When there is a duplicity of data in the different units that make up RAID 1, each disk can simultaneously transmit the information, so that the reading and writing speed of the set increases exponentially to the number of connected units. This RAID configuration requires at least two disks to work, and its capabilities are not added as in the case of RAID 0, but it is created based on the available space of the smallest disk. This is because, since the data is duplicated exactly on each disk, the smallest disk could not accommodate the largest data, so the set is adapted to the capacity of the smallest disk. Therefore, if you are going to create a RAID 1 with a 2 TB disk together with a 500 GB disk, the result will be a RAID 1 set of 500 GB, taking as reference the capacity of the smallest. RAID 5 Another of the most common RAID types is RAID 5. This type of storage arrays consist of a storage system distributed among all the disks that make up the set, to which parity information is added, offering an excellent tolerance to The falls. In fact, it could continue to work even when one of the disks has failed. RAID 5 divides the data into blocks of information that it distributes equally between the different disks, and adds a parity block (something like a backup of the data contained in each block of data) to a different disk, in which includes information of the blocks you have distributed. Thus, if one of the disks that make up the matrix fails, the system remains active by joining the data of the different blocks distributed in the rest of the disks, and it recovers the missing fragments of the disk that has failed from the parity block of These data. That is, taking into account the scheme above, if disk 2 fails, the system uses the information from blocks A1 and A2 and retrieves the data from block A3 from the parity block Ap of disk 3. When the damaged disk, the system restores the missing blocks in that unit and everything goes back to normal. To the excellent tolerance to failures of RAID 5 is added the possibility of accelerating the speed of reading and writing, provided that the data requested are in different disks, so this increase in performance is not a constant. Everything you need to know about hard drives This type of RAID is very commonly used in NAS storage and in external storage systems, or backup units because it is the most reliable system for not losing data. To create a RAID 5 you need a minimum of three disks to form a matrix, since in the first two the distributed data blocks would be created, in the third the parity block and so on. Nested RAID arrays: RAID 0 + 1, RAID 1 + 0 and RAID 5 + 0 We have already commented that RAID systems behave as independent logical units, so it is possible to create a RAID matrix by combining different RAID arrays as disk drives. These are the so-called nested RAIDs. Some of the best known are the matrices RAID 0 + 1, RAID 1 + 0. Now that you know the main types of RAID, you will better understand how they can be combined to create new matrices. RAID 0 + 1 The RAID 0 + 1 system (or RAID 01) consists in the use of two RAID 0 matrices to create a RAID 1 matrix, which increases the performance, maintaining a greater tolerance to the failures since the data of one of the RAID 0 matrices are duplicated in another matrix of the same characteristics. With this union of RAID matrices, it is possible to duplicate the performance of the disk units (through RAID 0), but maintaining fault tolerance (through RAID 1). RAID 1 + 0 The system in RAID 1 + 0 (or RAID 10) is just the reverse of what we have seen in RAID 0 + 1. In this type of RAID, two matrices are used in RAID 1, to create a RAID 0 matrix. The objective is to maintain reliability, but by accelerating the access speeds to the data provided by RAID 0. The main difference between RAID 01 and RAID 10 is the way in which the data is distributed in each RAID. In RAID 0 + 1, in case of failure of a RAID 0 disk, the backup support is in the second RAID 0 that has been linked by RAID 1. In contrast, in RAID 1 + 0, each matrix RAID 1 has its own independent backup support. RAID 5 + 0 The RAID 5 system also has a nested variant, which combines the reliability of RAID 5 with the access speed of RAID 0. The RAID 5 + 0 (or RAID 50) retains the great tolerance to failures of RAID 5, improving the speed of access to each disk through a RAID 0 matrix that keeps connected a minimum of three RAID 5 arrays. The main difference between RAID 01 and RAID 10 is the way in which the data is distributed in each RAID. In RAID 0 + 1, in case of failure of a RAID 0 disk, the backup support is in the second RAID 0 that has been linked by RAID 1. In contrast, in RAID 1 + 0, each matrix RAID 1 has its own independent backup support. RAID 5 + 0 The RAID 5 system also has a nested variant, which combines the reliability of RAID 5 with the access speed of RAID 0. The RAID 5 + 0 (or RAID 50) retains the great tolerance to failures of RAID 5, improving the speed of access to each disk through a RAID 0 matrix that keeps connected a minimum of three RAID 5 arrays. A RAID does not replace a backup In the face of possible confusion, it is important to clarify that a RAID configuration will not protect your data from an attack by ransomware or viruses that corrupt the files, since it does not encrypt or protect access to data, but rather makes them more tolerant of mechanical failures. discs. If a virus or malware attacks a RAID system, the data it contains can also be encrypted or deleted, just as you could manually delete it. In addition, this type of configuration does not make the recovery of the system simpler either. Therefore, it never hurts to have an additional backup from which to rescue your operating system or your data. Can I configure a RAID on my PC? There are two ways to create a disk array in RAID: hardware RAID and software RAID. To create a disk array in RAID using hardware all you need is that the motherboard of your PC has a storage controller compatible with RAID. This data is usually indicated in the specifications of the motherboard. In these specifications you will also find in which connectors this feature is supported and what types of RAID are compatible with your motherboard. If the motherboard supports the creation of a RAID, it will be sufficient to connect the disks to the appropriate SATA ports, configure the matrix from the BIOS or UEFI of the equipment and the system will recognize it as a single storage unit. How to convert an old hard drive to an external disk If the motherboard of your computer does not offer support for RAID, or does not support the type of RAID you want to create, it will not be a problem either. You can add an external controller via PCI that will allow you to create the disk array in RAID by connecting the drives to the card, instead of directly to the motherboard. On the other hand, regardless of whether the motherboard of your computer has support for RAID systems or not, you can also configure a RAID matrix using software. The operating system is responsible for this task, which will emulate the behavior of a RAID controller to distribute the data in the disks configured for this purpose, showing itself as a single storage unit. In the case of Windows, this configuration of disks in RAID is done from the Windows Disk Administrator. In this step by step we show you how to create a software RAID from Windows. The configuration of a RAID on Mac is done through the Disk Utility tool, while for GNU / Linux systems it will be necessary to install the mdadm package that manages the creation of the RAID.

Google engineers have found a bug in Microsoft Edge that even those in Redmond could not solve even though they were notified more than 30 days ago. Microsoft Edge was born to become the best browser in the world to try to recover the lost hegemony against Google Chrome, and is still far from that goal. Most users of Windows 10 prefer to continue using Chrome instead of Edge for its higher level of security and custom, and it seems that Remdond still has a lot of work to do. Project Zero, the Google team that looks for holes and security flaws in applications of all kinds, has uncovered a major bug in Microsoft's Edge browser and is related to the ACG and JIT, systems used to prevent the execution of arbitrary code in the browser and that, it seems, does not work at all well. ACG is one of the main novelties included with Windows 10 Creators Update and was created to avoid the execution of arbitrary codes designed to perpetrate attacks on the receiver's system. The problem as Google has discovered, is that there is a conflict with JIT where JavaScript is transformed into native code enabling the possibility of unsigned code and, therefore, insecure. When these types of failures are discovered from Project Zero 90 days are given for the owner to solve the problem, a time that has already passed without Microsoft having been able or willing to solve this security hole. It is unknown if Microsoft will end up including a next update to solve a problem that seems not to give much importance.
