Processor Breakthrough Could Double Speeds

A new approach to computer processing could double speeds while halving power consumption, according to researchers. The approach could work on existing hardware without needing physical modifications. The research builds on the existing technique ... of multithreading. That's an attempt to overcome the major limitation of computer processors (CPUs). They are broken down into cores (often 2, 4 or 8 cores) but each core can only carry out one task at any specific split-second. Workload Optimized Threading means breaking bigger tasks down into a list of individual steps known as a thread. The ... (view more)

Liquid Metal Could Transform Computer Memory

Researchers in China have found a way to make flexible computer memory using liquid metal. It could one day revolutionize the physical design of computer devices. Anyone who has handled either internal computer RAM or a flash memory device will know ... that bending them even slightly would not end well. That's partly because the electronics is housed on often-brittle plastics, but partly because those electronics need to be flat and inflexible themselves. In very simple terms, RAM uses flat, two-dimensional electronic grids. Each point where a horizontal and vertical line crosses is a cell that ... (view more)

New Error Correcting Could Reduce AI Hallucinations

A physical limitation in traditional computers could be harnessed to power artificial intelligence according to a start-up business. They've demonstrated what they call a "thermodynamic computer." The research is all about the way that computers use ... a physical process to carry out a digital, mathematical operation. All traditional computing boils down to a circuit board using electronic switches to represent and process data as either a 1 (for "true") or a 0 (for "false"). The physical aspect can lead to problems, however. New Scientist gives the example of a component ... (view more)

WhatsApp Change May Hit Google Storage

WhatsApp users on Android could hit storage limits thanks to a change in Google policy. However, claims it could mean a "shock new fee" are misleading at best. Users of the popular messaging app can have their messages, including videos and images, ... automatically backed up from an Android device. However, WhatsApp itself does not handle the backup or store the data. Instead the backup is on Google Drive. Because WhatsApp doesn't hold backups itself, the Google Drive backup may be the only way to restore data when moving to a new phone, particularly when the old handset is broken or unavailable ... (view more)

Marketers Claim to Listen In on Households

A marketing company claims it can listen in to private conversations in peoples' homes and gather data for targeted advertising. It's not clear if Cox Media Group (CMG) is "revealing" a poorly kept secret or exaggerating its capabilities to boost ... business. The claims were made by CMG's marketing team in a pitch to other marketers. The details were revealed through a leak to 404 Media. (Source: 404media.co ) According to the report of the leak, CMG promoted the technology as "Active Listening" and asked potential clients "What would it mean for your business if you could target potential ... (view more)

Artists 'Poison' AI Image Tools

Disgruntled artists have exploited a flaw in artificial intelligence image generators to "poison" their learning. They are looking for revenge on AI operators who use artwork without permission to train their tools. Like most generative AI, image ... tools learn by analyzing millions of pictures and accompanying captions. In turn, the AI creates its own checklist for what particular words or phrases mean. They also learn styles of image and art. While some AI tools are "trained" with permission on libraries of licenses of images, others simply trawl the Internet and use any images they can find. ... (view more)

Wi-Fi 7 Offers 4X Speed at 46 Gigabit

The next generation of WiFi will be available by spring, 2024. WiFi 7 should be up to four times faster than the previous generation. The theoretical maximum speed of 46 Gbps (gigabit) is not something anyone is likely to see in their home setup. ... However, it could make it more likely that users will be able to take full advantage of even the fastest home broadband connections. For those unaware, one gigabit is equal to 125 megabytes. Therefore, 46 gigabits is 5750 megabytes. Most standard hard drives today transfer speeds of around 100+ megabytes per second (not includes NVMe or SSD). For ... (view more)

7 Million Affected By DNA Website Breach

DNA and ancestry site 23andMe has admitted nearly 7 million customers are affected by a data breach. Both the breach itself and the way the site organizes its data contributed to what could be a legal disaster for the company. 23andMe is named after ... the number of segments of DNA that people share with each parent. The service involves customer submitting a DNA sample to be used either to check for genetic health conditions, get information about ancestry such as ethnic origin, or both. Customers can also agree to be put in touch with other customers when a DNA match suggest a possible family ... (view more)

Study: Videoconferencing Mentally Draining

Video calls could cause more mental fatigue than in-person events according to a recent study. Although the study was on a very small scale, the researchers said the differences were "notable." Austrian academics said they wanted to find out if ... widespread anecdotal reports of "videoconferencing fatigue" were true. They defined the effect as "somatic and cognitive exhaustion that is caused by the intensive and/or inappropriate use of videoconferencing tools." In other words, the exhaustion affected both the mind and the body. The researchers asked 35 students to wear heart monitoring and ... (view more)

GPS Tool to Warn of Local Crash Risks

A Google-owned map tool will now warn drivers about known accident hotspots. But the information might not be all that useful for now. The new feature is in Waze, a GPS navigation tool that began in 2006, with Google buying it out in 2013. It's ... original selling point was that it combined data from multiple users to spot where they were driving slower than expected, indicating congestion. It then adjusted its recommendations for the quickest routes. Although Google owns Waze, it still operates as a separate service. That lets Google use it as a smaller scale test ground for features that might ... (view more)
