  Fujitsu New Tech to Detect ETH Smart Contract Bugs

Japanese IT giant Fujitsu has revealed a new technology that it says could help to mitigate problems with ethereum's smart contracts.

In a statement released Wednesday, Fujitsu said the new system aims to detect in advance the risks associated with a smart contract source code on ethereum. In effect, the tech helps the blockchain authenticate the source call that triggers smart contract transactions.

Smart contracts are a primary feature differentiating ethereum from bitcoin, enabling developers to build applications on top of the ethereum blockchain to automatically execute programming orders (or contracts).

However, Fujitsu said that, currently, there are six common risks associated with the platform. While existing technologies are capable of solving most of those issues, the authenticity of the source call still remains problematic.

For instance, as the firm explained, since multiple smart contracts could have been built indirectly into a blockchain, there's a risk that the system may not correctly execute the original intention of a source call.

Reality 2.0: A Way to Upgrade Your Perception of Reality
By Maxim Roubintchik - Dec 24, 2017

Imagine enhancing your perception of the environment around you, other people nearby, and even yourself. Imagine reliving past experiences as if they are happening right now. Imagine a crumbling border between physical and virtual reality. Such a future is closer than you might think.

The basic premise of reality 2.0 is to bridge the gap between two worlds: The physical reality we experience and a possible digital reality that you imagine. This would go beyond overlaying digital things on the physical world, like a virtual Pokémon on the table, using current augmented reality.

Reality 2.0 is literally replacing your visual perception of the world with a fully virtual 3D environment.

How might this work? Imagine taking an exact laser scan of your current environment—your living room or office space, or any other thing—and using this to create a virtual 3D replica of everything around you. Now, re-create the room in VR and overlay the real world with the virtual experience. If you get there, you’re golden. You are experiencing an upgradable version of reality in which you can modify the elements of your virtual world however you desire.

Reality 2.0 might seem like a distant future. But it isn’t.

To showcase the possibility, I sat down for three days—limiting myself to a short amount of time—to build a simple prototype in my living room. Using a laser scan from a Hololens, I created a virtual version of the room. Because my virtual view is synchronized with my actual living room, it becomes a room-scale VR experience that replaces my perception of the world with the digital version created in a 3D engine.

Welcome to a World Only Limited by Your Imagination
Full control over your perception will let you do some pretty spectacular things, like replacing a random person with a famous actor in real-time, transforming your current room into a beach hut, re-experiencing any given moment that happened in this room, and much more

Team Miles, a group of 12 citizen scientists that formed out of the Tampa Hackerspace, is competing in NASA’s first in-space Centennial Challenge: the Cube Quest Challenge.The mission at hand is to build a CubeSat that’s capable of advanced propulsion and communication in deep space, and of achieving lunar orbit. According to NASA, this marks the first time that private entities have had the chance “to compete to operate at the moon and beyond.”

NASA is offering three free payload slots on its Space Launch System rocket, which is scheduled to blast off on Orion’s first unmanned lunar flyby in 2018. The top three teams at the end of four preliminary ground tournaments will win the free slots, enabling them to compete with a larger pool of paying contestants in the lunar and deep space derbies. One free slot is worth about $2.5 million, and opens up the chance to win prizes for the in-space achievements. In total, NASA is promising $5.5 million in ground tournament and derby prizes.
