5 trillion bytes a day: SpaceX engineers flash some facts about Starlink satellites

SpaceX’s Starlink satellite constellation is still deep into testing mode, but it’s already generating 5 trillion bytes of data on a daily basis and getting software updates on a weekly basis.

Those are a couple of the nuggets coming from a weekend Reddit “Ask Me Anything” session featuring SpaceX’s software team.

The main focus of the online chat was SpaceX’s successful mission sending NASA astronauts Bob Behnken and Doug Hurley to the International Space Station in a Crew Dragon capsule — but one of the team members, Matt Monson, has moved on from Dragon to take charge of Starlink software development.

MIT fit tens of thousands of artificial brain synapses on a single chip

Someday, we might be able to carry around tiny, AI brains that can function without supercomputers, the internet or the cloud. Researchers from MIT say their new “brain-on-a-chip” design gets us one step closer to that future. A group of engineers put tens of thousands of artificial brain synapses, known as memristors, on a single chip that’s smaller than a piece of confetti.

In a paper published in Nature Nanotechnology, the researchers explain how their brain-inspired chip was able to remember and recreate a gray-scale image of Captain America’s shield and reliably alter an image of MIT’s Killian Court by sharpening and blurring it. Those tests may seem minor, but the team believes the chip design could advance the development of small, portable AI devices and carry out complex computational tasks that today only supercomputers are capable of.

“So far, artificial synapse networks exist as software. We’re trying to build real neural network hardware for portable artificial intelligence systems,” says Jeehwan Kim, associate professor of mechanical engineering at MIT. “Imagine connecting a neuromorphic device to a camera on your car, and having it recognize lights and objects and make a decision immediately, without having to connect to the internet.”

Google Sued for Secretly Amassing Vast Trove of User Data

Google surreptitiously amasses billions of bits of information —every day — about internet users even if they opt out of sharing their information, three consumers alleged in a proposed class action lawsuit.

“Google tracks and collects consumer browsing history and other web activity data no matter what safeguards consumers undertake to protect their data privacy,” according to the complaint filed Tuesday in federal court in San Jose, California.

The lawsuit argues that while Google lets users turn off data collection when using its Chrome web browser, other Google tools used by websites themselves scoop up their data anyways. The suit includes claims for invasion of privacy and violations of federal wiretapping law.

SpaceX will answer Crew Dragon and Starlink questions on Reddit at 3PM ET

If you’ve wanted to learn more about SpaceX’s projects than you normally see in the news, now’s your chance. The company’s software team is holding a Reddit AMA session today starting at 3PM Eastern to answer questions on the software that guides SpaceX’s projects, including Crew Dragon and Starlink. Six key staffers will be on hand, so you can expect a fair number of responses.

The spaceflight firm doesn’t hold AMAs often, and it’ll likely be worth following the discussion to see what emerges. When Elon Musk held a Reddit chat about BFR (now Starship) in 2017, for instance, he touched on everything from engine design to his vision for Mars colonies. You won’t necessarily get any shocking revelations, but this could fill in some knowledge gaps and satisfy your curiosity.

If transistors can’t get smaller, then software developers have to get smarter

In 1965, Intel co-founder Gordon Moore predicted that the number of transistors that could fit on a computer chip would grow exponentially —- and they did, doubling about every two years. For half a century Moore’s Law has endured: computers have gotten smaller, faster, cheaper and more efficient, enabling the rapid worldwide adoption of PCs, smartphones, high-speed Internet and more.

This miniaturization trend has led to silicon chips today that have almost unimaginably small circuitry. Transistors, the tiny switches that implement computer microprocessors, are so small that 1000 of them laid end-to-end are no wider than a human hair. For a long time, the smaller the transistors were, the faster they could switch.

But today, we’re approaching the limit of how small transistors can get. As a result, over the last decade researchers have been scratching their heads to find other ways to improve performance so that the computer industry can continue to innovate.

Can Vertical Farms Fix the Future of Food?

Singapore has only 1% of its land available for agriculture, so it imports 90% of its food requirements. The government is looking to curb this dependence on outside food sources under a programme titled ‘30 by 30,’ which aims to allow Singapore to grow 30% of its produce by the year 2030. Local vertical farms like Sustenir are at the forefront of bringing about this change. VICE visits the sustainable start-up to understand the future of food.

IoT, AI and blockchain will change every aspect of enterprises and our lives: Oracle

The current health crisis has snowballed into a world economic crisis, where every old business norm has been challenged. In such times, we cannot fall back on old ways of doing our business. Today, three technologies

Internet of Things(IoT), Artificial Intelligence (AI), and blockchain are poised to change every aspect of enterprises and our lives. Now more than ever, organisations realise the pertinent need for a robust digital foundation for their businesses as their future plans have been disrupted. “To achieve that level of business sophistication holistically it is imperative that there is a seamless flow of data across all the functions of an enterprise. That requires connected data that is secure and one that is driven by connected intelligence,” Guruprasad Gaonkar, JAPAC SaaS Leader for ERP & Digital Supply Chain, Oracle told Moneycontrol in an interview:

How is India reacting to emerging technologies as compared to other Asia Pacific (APAC) regions?

Taiwan Draws Up Plan to Woo $1.3 Billion of Annual Tech Research

The endeavor escalates global competition for much-sought-after semiconductor technology and is intended to build on the island’s technology industry, led by major players such as key Apple Inc. suppliers Taiwan Semiconductor Manufacturing Co. and Hon Hai Precision Industry Co. Taiwan has been caught in the middle of a clash between the U.S. and China over the development of chip technology that powers everything from smartphones to 5G base stations.

Taiwan is dangling incentives to attract more than NT$40 billion ($1.3 billion) of annual investments in research and technology, creating a seven-year blueprint to safeguard the island’s lead in semiconductors and other cutting-edge fields.

As part of the initiative, the cabinet plans to allocate more than NT$10 billion to entice foreign chipmakers to set up R&D facilities locally, confirming an earlier Bloomberg News report. The government said Thursday it aims to subsidize as much as half of all research and development costs incurred by global chip companies that build centers on the island.

The modern world is fast becoming a wireless, infrared world

Optics-based technologies such as optical fibers have strongly influenced the age of wired communication. Now they look set to revolutionize wireless communications as well and solve key issues with traditional radio-based approaches by using steerable, narrow infrared beams to send large amounts of data to user devices individually in an energy efficient and secure manner. Researchers at Eindhoven University of Technology are developing new methods for infrared wireless communications that could change how we access data forever.

The modern world is fast becoming a wireless, infrared world! Until now, the majority of wireless communications, both indoor and outdoor, have been radio-based. Although signal modulation techniques can squeeze more data into the limited radio-frequency spectrum and spatial multiplexing can combine multiple data signals into one signal without requiring more spectrum, we are struggling to meet our exponentially growing data demands.

The solution could be optical wireless communications, which use over a wide spectral range from a few hundred nanometers to a few micrometers that includes visible and infrared radiation. Ton Koonen and researchers at the Institute for Photonic Integration are designing prototype systems with a capacity of more than two thousand times that of current shared WiFi systems. They have presented their work in an invited paper for the themed issue, “Optical Wireless Communication,” of the Royal Society’s Philosophical Transactions A, the oldest ongoing scientific journal in the world. Isaac Newton’s first paper, “New Theory about Light and Colours,” was published in the same journal in 1672.
