In geology, the black tourmaline stone is usually schorl, a member of the broader tourmaline mineral group. In crystal healing circles, the deep-black crystal has a big reputation in spiritual practices. People use it for protection, grounding and energy clearing in daily life.

The largest Hindu temple in NJ (New Jersey) is BAPS Swaminarayan Akshardham in Robbinsville, New Jersey, a vast Hindu temple complex where stone, worship, Indian culture and community life all meet on one campus.

Last.fm announced that it is independent again after separating from Paramount Skydance, nearly two decades after CBS acquired the music-tracking service in 2007. The company says accounts, scrobbles, privacy settings, Pro subscriptions, and billing information will remain intact. Additional details are forthcoming. Engadget reports: "Today, Last.fm begins a new chapter as an independent company," the announcement reads. "Ownership has changed, but the product you use every day has not." It also said that it will keep its current team. Last.fm is a music website that can track what you listen to across platforms, apps and streaming services, including Spotify, YouTube and Apple Music. [...] Last.fm started as an internet radio station in 2002, and it didn't get scrobbling until a few years later when it merged with the original team that created the tracking process. It operated as an independent company until it was acquired by CBS Interactive, which is now part of the merged Paramount Skydance Corporation, for $280 million in 2007. In 2014, it killed off its $3-a-month subscription radio service to focus on tracking your listening habits on other providers. The company promised to share more about what you can expect from the transition in the coming weeks, but everything will work on Last.fm "exactly as it did yesterday" for now.

ETH Zurich researchers say they have generated certified "perfect randomness" for the first time by using a quantum Bell-test setup with two entangled superconducting chips connected by a 30-meter cooled link. "In the long term, this work could play a similar role in digital security as atomic clocks do for timekeeping: a physically certified source of randomness that other systems can rely on," reports Phys.org. "Possible applications range from the encryption of sensitive communications and digital identities to public randomness services for lotteries and blockchain applications." From the report: They call their method randomness amplification. "This was made possible by an improved so-called Bell-Test with simultaneously high quality and high data rate," says [Renato Renner and Andreas Wallraff]. He and his coworkers use a complex setup that consists of two superconducting chips, which they cool down to very low temperatures close to absolute zero. Each chip represents a quantum bit or qubit, which can take on the states "0" or "1" or any arbitrary superposition of these states. A 30-meter-long tube, which is also cooled down, connects the two chips. Microwave photons can fly back and forth between them, thus creating quantum mechanical entanglement. This means that a quantum measurement on one qubit, which randomly yields the values "0" or "1," influences automatically and at a distance whether "0" or "1" is measured on the second qubit. The separation of 30 meters ensures that, during the measurement, even at the speed of light, no information can be exchanged between the qubits. This would disturb the perfect randomness. Wallraff and his team made the choice of the exact type of measurement (or "measurement basis" in technical jargon) on the two qubits depending on an imperfect random number generator. Renner's coworkers could then amplify the randomness of the measurement results further using a special algorithm. "The resulting sequence of zeros and ones is now really perfectly random, and we can even certify that," says Renner. He likens this result to crossing a ridge: "The technical improvements allowed us, for the first time, to create random numbers that will remain perfectly random for all eternityâ"no matter what analytical methods are used to assess their randomness." The findings have been published in the journal Nature.

An anonymous reader quotes a report from Ars Technica: Now sites have a new way to spy on their visitors: measuring subtle interactions with their solid-state drives. The technique, named FROST (fingerprinting remotely using OPFS-based SSD timing), allows sites to monitor other sites a visitor is viewing and what apps are open on their devices. The technique, laid out in a research paper (PDF), exploits a side channel, a form of leak resulting from physical manifestations such as electromagnetic emanations, data caches, or the time required to complete a task. By measuring the manifestations, attackers can decrypt encrypted traffic and infer other confidential data. The attack that FROST uses is known as a contention side channel, which measures the interaction of various processes all using (or competing for) a given resource. By measuring the timing of certain I/O (input-output) operations of the SSD a visitor is using, the researchers were able to determine the websites open in other tabs -- even on other browsers -- and the apps that were open on the visitor's device. FROST requires no interaction from the visitor other than opening the site hosting the attack. [...] Unlike previous contention side-channel attacks on SSDs, FROST runs exclusively in the browser. It uses JavaScript that interacts with the OPFS (origin private file system), an allocated storage space that's reserved for a specific site to run code needed to complete a given task. Websites can create one with no interaction required by the visitor. While each file system is sandboxed, meaning it's isolated from other websites and from the device system itself, the JavaScript can measure the I/O interactions. Then, by running those interactions through a pretrained convolutional neural network -- a system that uses deep learning to analyze text, audio, and images -- the attacker can deduce various apps and websites open on the device. "The attacker continuously measures SSD contention by performing random reads from a large OPFS file," the researchers explained. "SSD contention caused by user activity causes measurable latency differences for these read operations. By training a convolutional neural network (CNN) on these traces, the attacker can fingerprint user activity on the host system by classifying new traces using the trained model."

Meta will begin testing paid subscriptions for its Meta AI app and website, with a $7.99/month Meta One Plus plan and a more capable $19.99/month Meta One Premium plan offering. The test will start next month in Singapore, Guatemala, and Bolivia as Meta looks for AI revenue beyond advertising while continuing to offer a free tier. CNBC reports: Naomi Gleit, the head of product at Meta, revealed the subscription testing in an Instagram video, announcing that the plans "give people who use Meta AI more to work with, more capacity, bigger, more complex requests, and more room to create for businesses and creators." Meta One Plus will cost $7.99 a month and the Meta One Premium plan will cost $19.99 a month, the company confirmed. The more expensive version offers users additional computing capacity to produce more comprehensive responses and other advanced features. The company will continue to provide a free version of the app and site. "We're offering premium tools that allow you to enhance presence, supercharge content, automate tasks, and protect your brand," Gleit said in the post. "We're also thinking about how to bring this all together in a way that makes sense."
