Russians presented a tank with a 3D printer

3D printing technology seems to have infinite possibilities that are useful in almost every sector of the economy, allowing you to produce virtually everything from precision machine components through cars to home automation. The Russian Ministry of Defense has come up with another idea of ​​using 3D printers and presented a tank made with their help called Armata.

Electromashina, a part of the Uralvagonzavod corporation, has been working on this issue since last summer when it introduced the first models of industrial 3D printers. Since then, several prototypes and small parts have been created.

Anton Ulrich, head of Electromashina’s engineering department, points out that 3D printers make it easy to make component prototypes, which is especially important for more complex components, saving you the trouble and error of traditional production methods.

The components thus produced no longer need to be subjected to further processing, and no material losses. Components can also be manufactured with great precision to be immediately assembled in a built-in device. Thanks to 3D printers, prototyping is also becoming easier and it is possible to make molds for mass production of plastic or metal parts.

Yale University distributes ipads to students

Yale’s prestigious medical students will receive iPad 2 this fall, which will replace paper used to learn and collect patient data.

More and more universities are beginning to look at tablets and offer them to students, replacing paper. That’s what made Yale a prestigious college, which is planning to donate iPad 2 to medical students this fall.

Tablets will receive special software, which students will use during the first and second year of study. On the other hand, students of the third and fourth year will receive tablets containing information related to their specializations.

Yale claims that the solution is more eco-friendly and that, in his words, a photograph is presented showing how much paper savings will be replaced by a tablet. The picture shows a thin tablet, next to a giant heap showing the materials used by students only during the first two years. In addition to saving paper, students, thanks to an interactive learning style, will also be much better acquainted with knowledge.

Bridgestone tires will tell you about road conditions

The car tires used to be just rubber on a steel wire frame. For a few years now, every piece of equipment has become more and more advanced and more and more sensors appear in it. In addition to pressure sensors, we will soon have additional sensors that will tell us the conditions of the road.

Tire engineers from Bridgestone have developed a new type of sensor called Contact Area Information Sensing, which is installed on the inside of the tire, to monitor its interaction with the surface, providing drivers with real-time data on road conditions.

Technology has been developing since 2011 and was presented at the Frankfurt Motor Show at the time, and its first generation used a load-sensing sensor and lateral forces acting on the tire. A little later, CAIS 2 appeared, which was equipped with additional acceleration sensors that were used to determine the condition of the pavement. In 2014, Bridgestone showed CAIS 3, the latest generation of system, plus the ability to monitor the condition of the tire itself.

Now the Bridgestone management has announced the commercialization of CAIS 2, which it intends to use in passenger car and truck tires. They will be equipped with an accelerometer attached to the inner wall of the tire, which will be powered by an electromagnetic generator.

The solution will monitor high frequency vibrations on the tire and then transmit information via radio to the central module installed in the vehicle. There, using special algorithms, will be translated into information about current road conditions.

In this way, the driver will know in real time whether the road surface is moving, dry, wet, wet, covered with fresh snow, snow or ice. This is undoubtedly a very useful solution, as it is often difficult at first sight to notice that the surface can be slippery, and particularly tricky is the so-called. Black ice.

2 still the fastest supercomputer in the world

So far, many have been able to ridicule Chinese technical thinking, but the Asian tiger is increasingly showing its technological superiority to Western engineers, for example, the Tianhe-2, the supercomputer for the third time in a row, has been named the world’s fastest.

Tianhe-2 operates at the Chinese National Defense Technology University and according to Linpack benchmark, it has a computing power of 33.86 petaflops. This amazing performance has once again made it to the top of the Top500 list, presented at Monday’s International Supercomputing conference in Leipzig, Germany.

For a full list of all the most powerful supercomputers you will find on (-release /). The summary shows that the country with the largest number of such machines still remains the United States with 233 computers in operation. Their numbers shrank somewhat, because last year they were 265.

The number of Chinese supercomputers increased from 63 to 76, giving them a second place behind the US. The following items were: Great Britain – 30, France – 27, and Germany – 23 machines. I will add that all 500 classified machines have a computing power of 133.7 teraflops and is significantly higher than half a year ago when it was 117.8 teraflops.

On the other hand, the biggest computational power of a single supercomputer is the Chinese Tianhe-2.

Samsung and Google will expand Nexus

Nexus 7 slowly conquers the market by tempting consumers with high functionality and low price. But many believe the 7-inch screen is too small for them, so plans are for a new, much larger tablet model.

According to unofficial reports released by CNET analyst Richard Shim, Google along with Korean Samsung is developing a new, larger version of Nexus, which would have a 10-inch screen and would offer a screen resolution of 2560×1600 pixels, beating the head of the new iPad. A pixel density of 299 ppi.

Shim claims that the reports are reliable because they come from component suppliers and those in those cases are the best informed source.

The specialist also claims that in December, the production of a new tablet for Android should start at $ 99. It is not known if this will be a Nexus 7 variant, or a brand new model.

If the information is confirmed, it would be a great curiosity. As we all know, Nexus 7 is a work of Asus, so you might think that Asus will also be producing a larger model. Meanwhile, Samsung’s involvement suggests that Google is seeking to diversify its interests and does not want to bind to one partner.

Advanced technology in the new Gear VR

There is a Samsung patent on the net, suggesting that the new generation of Gear VR goggles can be significantly upgraded. The documents indicate that on board it has the opportunity to find the technology of eye and face tracking.

Samsung Gear VR is one of the cheaper ways of experiencing virtual reality, although not available to everyone. Goggles only work with selected smartphone models of this manufacturer, which limits their usability.

However, the company managed to maintain a low product price of $ 99, although it is occupied with some imperfections in terms of its functionality. Goggles do not offer the same capabilities as the Oculus Rift or the HTC Vive, so it is not easy to find the eye and face tracking functions.

Samsung also noticed the limitations of its product, as a patent appeared in the network, indicating that the new generation of Gear VR goggles could be greatly improved. Disclosed documents indicate that the device is likely to receive the missing technology. It will include a camera and LED lights that will be used to track the position of the head. On the other hand, the camera inside the goggles will monitor the face and eye position.

The science of witchcraft like “harry potter”

Interactive play does not have to be limited to the image displayed on the console. Everyone has the chance to play and practice using their body as one of the interface elements. Those interested in magic will find professional code-written literature that will teach you many useful spells and charms. Young archaeologists and paleontologists will find answers to how dinosaurs looked, how many bones they had and how millions of creatures moved.

According to the announcement on November 14, the long-awaited “Book of Spells”, which for every fan of the story of the young wizard Harry Harper, will appear in the sale will teach magic, charm and charms. For parents it is also an investment in the education of children. Sony has announced more games that will reach Wonderbook and Moove controller.

A hardcover book with graphic codes can turn into an amazing learning tool. On pages of chalky matte paper, the characters that the PS3 console camera interprets according to the game input are listed.

Along with Wonderbook appeared a book of spells, which contains secret knowledge, straight from Hogwarts. Children and adults will happily train with the greatest teenage levitation skills, catch a dragon or open the door with a wand and waving word.

We observe transactions but we do not know who is behind them

The Bitcoin Virtual Currency changes the economics of crime by providing encrypted fraud, an almost anonymous payment system independent of any central bank. The victim of ransomware – a malicious software that encrypts files and requires payment for their unlocking – receives a unique account affected by bitcoins. After getting some ransoms, some gangs pour bitcoins into the main wallet. Transaction monitoring, and all bitcoin are public, lets you see how the gigantic amounts of cybercriminals gain access.

“We are seeing some of these portfolios and we see millions of bitcoins worth millions. Looking at such huge untaxed amounts, I wonder if there are any cybercriminal unicorns, “says Mikko Hyppönen, F-Secure Research Director.

Unicorn is a term used in economics, which means a private technology company valued at more than one billion dollars, Uber, AirBNB or Spotify. For cybergangs the logic of action is similar, but there are differences such as lack of investors, administration and supervision.

Illegal business is profitable enough that some gangs provide customer service comparable to that of start-ups: cyberbots have their own site, FAQs, and even consultants.

Cybergang business model

Can the cyber-business model be compared to start-ups? Probably not. It is difficult to imagine selling cyber criminal business and finding investors. This would not be a problem in a Uber-like start-up, after which the queue is set up. Gangas ransomware, however, have to constantly look for ways to exchange earned bitcoins into cash.

“Hackers buy prepaid cards and sell them for example on Ebay,” says Mikko Hyppönen. Many gangs feast money in online casinos, but it is more complicated. Even if two gang members set up a game between them so that one of them loses all the money, then when the big sums count, the casino may consider acting suspicious and blocking the payout. That’s why gangs have started to use bots that play realistically, but they still lose – though not so clearly “- adds Mikko Hyppönen.

Prosecution of criminals

Law enforcement agencies are aware of the temptation of earning ransomware. Only in 2015, the FBI’s Internet Crime Complaint Center received “2,243 ransomware fraud complaints with a loss of more than $ 1.6 million”.

One example may be a loud attack on a Presbyterian medical center in Hollywood, which to recover their files paid a 40 bucks worth of ransoms worth $ 17,000.

“Officially, the FBI does not advise whether to pay a ransom or not,” said Sean Sullivan, F-Secure’s security advisor. “If the victims did not take proper precautions, then in many cases paying the ransom seems the only alternative to recovering files.”

Steam Machines will be the least profitable hardware

The Steam Machines project was supposed to be an attempt to introduce PCs to our showrooms. However, this may not be a good attempt, as industry insiders suggest that you can not earn much on this hardware.

PCs have for years been trying to compete with consoles in the entertainment field, trying to take over the video game market. The Steam Machine was meant to be a combination of the features of both devices, so to provide PC functionality with console comfort and the ability to play with the controller in the palm of your hand while sitting on a comfortable couch.

After presenting pricing models of individual manufacturers enthusiasm fell heavily when it turned out that the cheapest model Steam Machine cost over $ 700, while the most expensive one has to pay over $ 2,000. This is the amount you can buy a heavily developed gaming computer with no restrictions on the Steam OS Linux based Steam Steam operating system.

It is no wonder that the last days of Steam Machines seemed to be forgotten, especially as the companies involved in the production of these devices now claim that the profits from this market will not be too great. For example, Frank Azor, Alienware’s chief manager, admitted that this is his least profitable venture.

Even worse, some other companies from almost 13 involved in the idea, who have agreed to cooperate mainly because it is a venture of Valve. Now it seems that they can get a great deal on it, especially since the multitude of available configurations can make consumers have trouble making a specific choice.

The Japanese are working on solar orbital solar farms

Engineers from the Japanese space agency JAXA say they are taking another step closer to achieving a bold vision for the creation of a solar-powered space station that can send energy directly to Earth. So far, they have been able to transmit energy using the wireless method for about 50 meters.

Many scientists and engineers from all over the world have been dreaming for years to realize the vision of building an orbital solar farm that produces energy that would send energy to the surface of the planet. In this way, the energy needs of our globe could be fully met, without the need to consume fossil fuels or polluting the atmosphere caused by their burning.

Unfortunately, the construction of such a farm has many problems, and the biggest one is to develop a way to safely send the generated energy to the surface of the planet. Its quantities would be huge, so extreme precision is required.

The problem is solved by engineers from the Japanese space agency JAXA who have managed to reach the first step to success. Under laboratory conditions, wireless transmission of 1.8 kW of energy over a distance of more than 50 meters, ideally hitting a small receiver.

Engineers first changed the electrical signal to microwaves and then sent it to a receiver that converted electrons into electrons. This is the first successful experiment to send electrons over long distances at such high precision.
