Google is working on a project space elevator

According to a report by Fast Company, the Google X labs, working in secret on specific projects, have attempted to design a good orbital elevator to go into space.

Google X labs are a little hidden part of the iceberg google. far from the traditional activities of the Web giant, these labs are designed to perform operations research and development in all areas.   some of their projects been made ​​public, as automate cars or augmented reality glasses , others have leaked, as work on face recognition or voice recognition. The secrecy surrounding these laboratories will into their location, hardly do we know they are in the San Francisco Bay.

These secret laboratories would thus nurtured the ambition to build a space similar to that elevator recently referred by scientists at the International Academy of Astronautics. They had, however, referred to the difficulties of making such a project, and it seems that they are the same reasons that prompted Google to abandon the idea for the moment. The researchers include concluded that this would require "cables at least a hundred times stronger than steel more resistant than we know." If such a cable can be replaced by carbon nanotubes, the problem is in their design: for now,there is no cable carbon nanotube whose length exceeds the meter . The project has been shelved for now, but may well reappear soon as technological advances permit.

3D printing to create disposable UAVs

3D printing has the advantage of producing a real object in a relatively short period of time and "cost". Pushing the limits of this technology, engineers at the University of Sheffield have created a drone with the same print.

This 3D printed UAV is the work of the scientific research center of advanced manufacturing (CDMA). Taking the form of a flying wing, the prototype has been developed to best reduce the amount of materials needed for its construction. Thus, the unmanned craft 1.5 m wingspan was made from a Stratasys 3D printer using FDM technology. This extruded ABS plastic melt by depositing the layer by layer. In the end, the nine pieces that make up was created in less than 24 hours. For ease of transport, the apparatus can be disassembled into two. So this method opens the way to cheap and disposable but may also be able to fly over the sky drones.

For now, the prototype drone officiates as glider but its designers intend to equip a propeller propulsion system. A larger and more powerful model is also planned, carrying a GPS, an independent operating system and data recording.

Windows XP is over

Windows XP goes. The operating system of Microsoft, launched on 25 October 2001 , we said goodbye. Redmond today issued a last fix pack (the famous patch Tuesday) and urges the ultimate users of the operating system to migrate to a newer version of Windows . Microsoft gave a press conference yesterday evening, while focusing on its plans for Windows 8.1 and Windows Phone 8.1 update, also reported on the risks faced by users who still use the old OS.

On April 8, 2014 therefore marks the end of support for Windows XP. Microsoft will no longer publish any update of its operating system. Only companies can obtain updates from Microsoft updates sold at exorbitant prices because they require costly development teams. For the general public, no further update will be not released, except that published today. Clearly, what does all this mean? Here's a little summary of what you need to know:

• If you still use Windows XP today, all is not lost. The latest patches from being published , you theoretically still a few days before the first security vulnerabilities of the OS will be exposed by hackers. But it is imperative to hurry.
• The risk that the victim OS are significant security vulnerabilities are enormous. Windows XP is still installed about 27% of users worldwide, hackers already grind brains to discover vulnerabilities in the OS, which their will undoubtedly infect a machine, take control, to retrieve personal information from the remote user, etc..
• It is imperative to migrate to a newer system . It may be Windows 7 or Windows 8.1 Update (or even Vista, why not) or a Linux distribution. Note also that, to switch from Windows XP to a much more recent version of the system, and without loss of data, Microsoft recommends the application Laplink PCmover Express .
• If you wish to continue to use Windows XP temporarily, install a complete security solution. It will not protect you 100%, but will limit the damage until full migration.
• Finally, perhaps more anecdotal, Office 2003 is also patched today for the last time. The office suite can also be a victim of security breaches, it is strongly advised to migrate to a newer version of Office, or failing version to opt for a free solution as Appache OpenOffice .

Finally, for more details, please see our big file on the migration of Windows XP to Windows 7 or Windows 8 , as well as our FAQs stop supporting Windows XP .

The main battle tank of the future will be invisible

Obrum, the Polish defense company is currently developing an invisible battle tank. Straight out of Tron universe, the concept is known as the PL-01. Vehicle futuristic fight can go unnoticed by changing the temperature at its surface.

The goal is to avoid visual detection, infrared or radar based on deception. To do so, the fictional battle tank is equipped with temperature controllers panels. With this system, the vehicle can adapt its shielded depending on the temperature environment, thereby making the invisible thermal imaging analysis.

Kind of vehicle chameleon, it can also use its panels to reproduce a camouflage pattern, allowing it to blend naturally in nature. With camera mounted on top, an operator can steer enjoying a 360 degree view.

The production of PL-01 is expected to begin later in 2018 and whose assembly is scheduled for 2022.
