A friend asks to buy something online? Do not be fooled

A good friend on Facebook asks you to buy an item at auction? You better think about it.

Facebook’s gigantic community acts like a scam magnet, who probably never had an easier task in capturing people particularly vulnerable to societal tricks.

Can some one in the messenger communicate with someone to send hundreds of dollars? Of course.

A fresh example of such manipulation was shared by one of the site’s readers

Criminals, after gaining access to their Facebook account, probably spent some time specifying potential victims – close enough to be ready to bet hundreds of dollars without much suspicion.

As usual in this case, the person whose account was used by the criminals, most often informed by friends, finally learned the case.

It is only then she informs and apologizes to her friends. It’s also a good idea to have a technically savvy person check to see if your account has been compromised by malware infection.

Are you sure you would not be fooled? But before you start to criticize the credulity of the victim, remember that the scammers specializing in social engineering tricks spend most of their time choosing the “right”, vulnerable to a particular victim attack.

The only safeguard is a constant awareness of the dangers, so if you know such people, let them know.…

British scientists have created a non-invasive glucose meter

A team of researchers from the University of Leeds has developed a small, portable glucose meter that non-invasively measures blood glucose. The device uses nano-engineered silica glass, the touch of which initiates the process.

A low-power laser sends a ray to the finger, and the appropriate sensors measure the duration of fluorescence, thus allowing the glucose to be determined. Clinical tests confirm as much as 95.5% accuracy, and this is roughly the level achieved by current measurement methods, but does not require patient blood sampling.

The current prototype is still quite large and requires a large area where it can be laid. However, in the future the device will be miniaturized so that the patient can carry it with him. Scientists believe that it could be built into, for example, a smartphone or tablet, which would greatly increase the functionality of this technology.…

The prototype camera will look around the corner of the wall

MIT researchers often build a variety of interesting technologies, and their latest invention is a special kind of camera that can see what’s behind a corner of the wall. The new device, using advanced technology, can be extremely useful in building monitoring systems, but not only.

The prototype of the new camera can locate objects hidden behind the wall, such as people, and track their movement. Although similar systems existed similarly earlier, they were, however, expensive, complicated to operate, and operated only on short distances.

The invention of MIT researchers is devoid of all these disadvantages and is definitely more functional. The system uses a low-power laser that is able to create a three-dimensional image of an object hidden behind a wall. It is also considerably smoother and functions much better than the lidars used to date.

Within seconds it is able to precisely locate the object and then track its position in real time. The device shoots millions of short laser pulses into the floor, which bounces to form a scattered, spherical wave of light. A special camera capturing the image at high speed captures the reflected light and then the time it reaches the object and then returns, calculates its shape and direction of movement. The following video explains exactly how this technology works.…

Wheelchair controlled by ear tag in language

The new method of wheelchair control can be a breakthrough for many paralyzed people. The movement of the tiny magnet in the “earring” on the tongue is enough to drive the instrument.

“Science Translational Medicine” published an article presenting a new generation wheelchair control system. The paralyzed person inserts a small implant containing the magnet. There is a sensor in the steering system that detects even the slightest movement of the muscle.

The area of ​​the brain that is responsible for the movements of the tongue is proportionately very large. This is necessary for the proper functioning of speech apparatus. Because the language is incredibly flexible, hardware control can be extremely precise.

Another advantage of the new system is the fact that spinal cord lesions, which are one of the most common causes of paralysis, almost never come to the inertia of the tongue.

The magnet on the tongue can be used not only to control the wheelchair but also other complicated devices, including the computer.

The system was tested on a group of 34 people. Patients were delighted. They only took a few days to learn how to operate a trolley because it was very intuitive. Moving the language to the left simply means turning left and analogously in the opposite direction. However, the developers point out that the software can be freely adapted to the needs. For example, you can program a system so that when you touch a specific tooth, you have selected the phone number.…

See how the spaceship ends

Inventories for the International Space Station are delivered via automated vehicles, the so-called. Automated Transfer Vehicles, sent by the European Space Agency. What happens to these vehicles when they end their lives? Have a look.

Albert Einstein ATV-4 is the fourth unmanned spacecraft to deliver supplies to the ISS. It was launched in June of this year, and it was launched into space rocket Ariane 5. The bus-size vehicle has delivered a record load of more than 2.5 tonnes to the station, consisting of over 1400 items, from clothing to 3D space-shipped gadgets.

After discharging ATV-4 he took the waste from the station’s deck and was directed towards the Earth to fall into the Pacific. The following video, a combination of animation and photos taken by astronauts on the ISS, shows how the vehicle breaks down as it enters the terrestrial atmosphere, ending its life.

Another ATV shuttle, named Georges Lemaître, will be launched in June next year.…

Israel believes that soldiers will replace robots

According to Israeli defense forces, robots will play a key role in armed conflict in the near future. They are investing more and more money in research into newer and even more advanced types of machinery that will soon be able to replace soldiers.

Israeli Defense Forces (IDF) has been using unmanned vehicles for a few years, the most popular of which is the Guardium, a machine manufactured by G-NIUS Autonomous Unmanned Ground Vehicles. The device, which has been patrolling the Gaza Strip for six years, has been aging for some time. That is why this year will be replaced by a new model.

The machine called Border Patroller is a work of G-NIUS Autonomous Unmanned Ground Vehicles and was created in collaboration with Elbit Systems and Israel Aerospace Industries. The new equipment was built based on the powerful Ford F-350 Super Duty Truck, which was rebuilt to a remotely controlled military vehicle.

Border Patroller has a complete set of sensors for scouting missions, and as an accessory you can install a remotely controlled weapon system. Compared to the predecessor, the communication system as well as the control system has also been improved, so that it will be more responsive to the instructions given to it.

According to Major Lior Tarbelsii, Head of Ground Forces, future equipment of this type will play a key role in the battlefield, supporting infantry and engineering units. The sensors will be able to detect improvised explosive charges and tunnels in which terrorists can hide. In addition, nothing will limit visibility, as vision systems will be able to switch to infrared or thermal imaging.

The Israeli army plans to bring in more and more such machines. Another project is a robot named Loyal Partner, equipped with high-impact weaponry and a drive capable of dealing with field obstacles, will provide infantry protection. He will also go to places filled with explosives and where the enemy can ambush. The robot will already be partially autonomous and software will allow him to calculate the best route and avoid obstacles. Maintenance will still be handled by the operator.

The machine will be in service in the next few years.…

Spammers will taste their own weapons

Programmer Brian Weinreich has developed a tool that can be an effective weapon against spammers. The bot he creates is in discussion with him and he can pull her for a long time.

Nobody likes spamming our email inbox. Although there are ever more advanced filters eliminating such junk messages, spammers are becoming more and more creative in this area and are hard to get rid of.

Brian Weinreich also had this problem, so he started working on a bot two years ago to respond to spam and engage in discussions with people who send him off. Of course, it would be much easier to ignore this spam, but the bot’s intent was for spammers to lose time by running an automated conversation.

Its tool can respond to received emails and does it quite smoothly. Although it is not always 100 percent. Effective but in most cases his answers are coherent and can be confused with man. Bot primarily negotiates the price of the product he advertises, which of course encourages the spammer to discuss.

The bot author has placed his source code on GitHub so everyone can use it and improve it. And if you want to see sample interviews, I invite you here.…
