Artifact, Instagram founders’ News app, to shut down next month

Posted by in category: internet

The app also had a social media component, where users could create their posts by finding and sharing interesting links from around the web. Users could also like and comment on other users’ posts, and follow their favorite writers.

However, Artifact struggled to define its identity and value proposition in the crowded and competitive market of news and social media platforms. The app faced competition from established players like Twitter, Pinterest, SmartNews Apple News, and Meta’s own Instagram, which recently launched a new feature called Threads, which allows users to create and join conversations around topics they care about.

AI Image Generators Are Spitting Out Copyrighted Characters, Raising Possibility of Catastrophic Lawsuit

Posted by in categories: entertainment, internet, law, robotics/AI

Companies like OpenAI and Midjourney have opened Pandora’s box, opening them up to considerable legal trouble by training their chatbots on the vastness of the internet while largely turning a blind eye to copyright.

As professor and author Gary Marcus and film industry concept artist Reid Southen, who has worked on several major films for the likes of Marvel and Warner Brothers, argue in a recent piece for IEEE Spectrum, tools like DALL-E 3 and Midjourney could land both companies in a “copyright minefield.”

It’s a heated debate that’s reaching fever pitch. The news comes after the New York Times sued Microsoft and OpenAI, alleging it was responsible for “billions of dollars” in damages by training ChatGPT and other large language models on its content without express permission. Well-known authors including “Game of Thrones” author George RR Martin and John Grisham recently made similar arguments in a separate copyright infringement case.

Elon Musk’s Starlink satellites are “leaking” signals

Posted by in categories: Elon Musk, internet, physics, satellites

Thousands of satellites have been launched into Earth orbit over the past decade or so, with tens of thousands more planned in coming years. Many of these will be in “mega-constellations” such as Starlink, which aim to cover the entire globe.

These bright, shiny satellites are putting at risk our connection to the cosmos, which has been important to humans for countless millennia and has already been greatly diminished by the growth of cities and artificial lighting. They are also posing a problem for astronomers – and hence for our understanding of the universe.

Electric Light Transmits Data 100 times Faster than WiFi

Posted by in categories: chemistry, engineering, internet, security

Li-fi, a communication technology harnessing visible light for data transmission, has a potential to surpass Wi-Fi’s speed by more than 100 times and boasts a high bandwidth, facilitating the simultaneous transmission of copious information. Notably, Li-fi ensures robust security by exclusively transmitting data to areas illuminated by light.

Most important, it capitalizes on existing indoor lighting infrastructure, such as LEDs, eliminating the need for separate installations. However, implementing visible light communication (VLC) in practical lighting systems poses an issue of diminished stability and accuracy in data transmission.

Recently, a collaborative team led by Professor Dae Sung Chung, from the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH), with researcher Dowan Kim, Professor Dong-Woo Jee and Hyung-Jun Park from the Department of Intelligence Semiconductor Engineering at Ajou University, and Professor Jeong-Hwan Lee from the Department of Materials Science and Engineering at Inha University, succeeded in utilizing indoor lighting for wireless communication by reducing light interference with a novel light source. Their findings were published in Advanced Materials.

Single-Photon Source Marks Quantum Cryptography Gain

Posted by in categories: computing, encryption, engineering, internet, nanotechnology, quantum physics

Producing photons one at a time on demand at room temperature is a key requirement for the rollout of a quantum internet—and the practical quantum computers that would undergird that network. The photons can be used as quantum bits (qubits), the quantum equivalent of classical computing’s 0s and 1s. Labs around the world have devised various ways to generate single photons, but they can involve complex engineering techniques such as doped carbon nanotubes or costly cryogenically-cooled conditions. On the other hand, less complicated techniques such as using traditional light sources do not provide the necessary level of control over single-photon emissions required for quantum networks and computers.

Now, researchers from Tokyo University of Science (TUS) and the Okinawa Institute of Science and Technology have collaborated to develop a prototype room temperature single-photon light source using standard materials and methods. The team described the fabrication of the prototype and its results in a recent issue of the journal Physical Review Applied.

“Our single-photon light source … increases the potential to create quantum networks—a quantum internet—that are cost-effective and accessible.” —Kaoru Sanaka, Tokyo University of Science.
