Scientists hit a 301 Tbps speed over existing fiber networks

Posted by in categories: computing, internet

When I was a kid, I went to a science camp, and one of the instructors showed us a few inches of fiber optic cable. I remember thinking it was so neat that you could light it up at one end, and no matter how you twisted the cable, you could see the light come out on the other end. At the time, I thought how useful it might be to send Morse code through it—I was very young. Things have changed a bit since then. Today, UK Aston University researchers sent data at a 301 terabits per second (Tbps) clip over existing fiber networks.

How fast is that? It’s about 1.2 million times faster than the US’ medium fixed broadband speed of 242.48 megabits per second (Mbps). Or, it’s fast enough to deliver 1,800 4K movies to your home in a second. And I thought my recent home internet fiber upgrade to 2 Gigabits per second (Gbps) was impressive!Of course, no one will get 301 Tbps speeds in their home office. In the real world, I know a handful of people with 10 Gbps connections to their houses and many data centers with 40 Gbps local area networks.

Unlocking the Secrets of Eternal Data With Silicon Carbide

Posted by in categories: computing, internet, physics

Team presents new path to long-term data storage based on atomic-scale defects.

With the development of the internet, social media, and cloud computing, the amount of data created worldwide on a daily basis is skyrocketing. This calls for new technologies that could provide higher storage densities combined with secure long-term data archiving far beyond the capabilities of traditional data storage devices. An international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) now proposes a new concept of long-term data storage based on atomic-scale defects in silicon carbide, a semiconducting material. These defects are created by a focused ion beam, providing high spatial resolution, fast writing speed, and low energy for storing a single bit, as the team reports in the journal Advanced Functional Materials.

Latest estimates assume around 330 million terabytes of new data created each day, with 90 percent of the world’s data generated in the last two years alone. If the sheer numbers already suggest the need of advanced data storage technologies, it is by no means the only problem associated to this development. “The limited storage time of current storage media requires data migration within several years to avoid any data loss. Besides of being trapped in perpetual data migration procedures, this substantially increases the energy consumption, because a significant amount of energy is consumed in the process,” says Dr. Georgy Astakhov from the Institute of Ion Beam Physics and Materials Research at HZDR.

Google to settle spying lawsuit in shame, delete billions of records

Posted by in category: internet

The settlement terms include Google deleting ‘billions of data records’ that are from the private browsing activities of users involved in the suit. Going forward, Google will also update its disclosure to make users aware of what data it retains from the private browsing sessions.

As per the settlement, Google will also let people using the Incognito mode block third-party cookies for the next five years. The company will also not track the user’s choice of privately browsing the internet.

Frontiers: The Internet comprises a decentralized global system that serves humanity’s collective effort to generate

Process, and store data, most of which is handled by the rapidly expanding cloud. A stable, secure, real-time system may allow for interfacing the cloud with the human brain. One promising strategy for enabling such a system, denoted here as a “human brain/cloud interface” (“B/CI”), would be based on technologies referred to here as “neuralnanorobotics.” Future neuralnanorobotics technologies are anticipated to facilitate accurate diagnoses and eventual cures for the ∼400 conditions that affect the human brain. Neuralnanorobotics may also enable a B/CI with controlled connectivity between neural activity and external data storage and processing, via the direct monitoring of the brain’s ∼86 × 109 neurons and ∼2 × 1014 synapses. Subsequent to navigating the human vasculature, three species of neuralnanorobots (endoneurobots, gliabots, and synaptobots) could traverse the blood–brain barrier (BBB), enter the brain parenchyma, ingress into individual human brain cells, and autoposition themselves at the axon initial segments of neurons (endoneurobots), within glial cells (gliabots), and in intimate proximity to synapses (synaptobots). They would then wirelessly transmit up to ∼6 × 1016 bits per second of synaptically processed and encoded human–brain electrical information via auxiliary nanorobotic fiber optics (30 cm3) with the capacity to handle up to 1018 bits/sec and provide rapid data transfer to a cloud based supercomputer for real-time brain-state monitoring and data extraction. A neuralnanorobotically enabled human B/CI might serve as a personalized conduit, allowing persons to obtain direct, instantaneous access to virtually any facet of cumulative human knowledge. Other anticipated applications include myriad opportunities to improve education, intelligence, entertainment, traveling, and other interactive experiences. A specialized application might be the capacity to engage in fully immersive experiential/sensory experiences, including what is referred to here as “transparent shadowing” (TS). Through TS, individuals might experience episodic segments of the lives of other willing participants (locally or remote) to, hopefully, encourage and inspire improved understanding and tolerance among all members of the human family.

“We’ll have nanobots that… connect our neocortex to a synthetic neocortex in the cloud… Our thinking will be a… biological and non-biological hybrid.”

What’s next for generative video

Posted by in categories: business, internet, robotics/AI

A number of companies are racing to make a business on the back of these breakthroughs. Most are figuring out what that business is as they go. “I’ll routinely scream, ‘Holy cow, that is wicked cool’ while playing with these tools,” says Gary Lipkowitz, CEO of Vyond, a firm that provides a point-and-click platform for putting together short animated videos. “But how can you use this at work?”

Whatever the answer to that question, it will probably upend a wide range of businesses and change the roles of many professionals, from animators to advertisers. Fears of misuse are also growing. The widespread ability to generate fake video will make it easier than ever to flood the internet with propaganda and nonconsensual porn. We can see it coming. The problem is, nobody has a good fix.
