Amazon has unveiled home devices for receiving its satellite broadband service. It hopes to offer service by late next year but hasn't yet revealed pricing. Satellite Internet is one of the major ways tech firms are attempting to solve the problem ... of high-speed Internet access in rural areas. Installing fiber cable there doesn't usually make financial sense to profit-driven businesses because there aren't enough potential customers to justify the cost of installing it and/or paying for the parts to install it in non-densely populated areas. Such locations are also often outside the range of ... (view more)

Microsoft and Google have both put plenty of effort into artificial intelligence in recent months. After an initial wow factor, they've been plagued with a host of problems. Interest in AI-text shot up with the public release of ChatGPT, a tool that ... can not only simulate conversations with the user and answer questions, but also write articles and other text in a variety of styles. While it appears extremely clever, it's effectively an extremely souped-up version of the auto-predict feature many phones offer when sending text messages. ChatGPT is produced by an independent developer called ... (view more)

The market for smartphones, tablets and PCs will shrink for a second straight year according to a newly-published forecast. The phone slump could mean the lowest number of units leaving manufacturers since 2009. Gartner, which produced the figures, ... says factors behind the trend include the economy, changing consumer behavior, and a lack of innovation. The forecast isn't for sales but rather shipments: that is, the number of devices which manufacturers send to retailers. It's affected by both recent sales and forecast for future sales. For example, shipments may drop if retailers have a ... (view more)

Changes to a major rival of Bitcoin have reduced energy use by 99 percent. The drop in computer processing for Ethereum has been likened to the amount of electricity used by a "mid-size country." The change has come after the Ethereum blockchain ... switched from proof-of-work to proof-of-stake, a sentence that makes little sense to most normal people. To break it down, a blockchain is a digital list of transactions. The key is that it doesn't exist as a single copy but rather multiple copies across all the computers of all users. In theory at least, this means it can't be edited or falsified ... (view more)

Researchers say they used a single five-mile cable to transmit twice the amount of data that's currently used by the entire Internet. While it could one day mean faster connections for users, the main benefit of the research could be more ... energy-efficient data centers. The project involved the Technical University of Denmark and the Chalmers University of Technology in Gothenburg. They explored the way most high-speed data connections today involve encoding signals to transmit as light. The key was combining a single laser with a specially-designed optical chip. This breaks the light into 223 ... (view more)

Additive manufacturing is the process of creating an object by building it one layer at a time - similar to a 3D printer. The method was initially geared at quick prototyping, producing pieces for testing and iterative design. However, during the ... past five years, engineers from all over the world have begun to concentrate on finding appropriate uses for final products and realizing the full potential of additive manufacturing. There are hundreds of potential products in every business, whether it be healthcare, aerospace, automotive, logistics, or consumer goods. Using sliced computer aided ... (view more)

Phones and tablets sold in Europe from 2024 may need to use USB-C charging ports in a blow to Apple. The rules could affect handsets around the world depending on how manufacturers respond. The rules would come through a European Union directive, ... which means all 27 EU countries would need to pass the measures into their national laws. Although the draft directive has been published, they won't take force until the European Parliament has voted to adopt them. The logic is that the rules would let users have a single charger for all small portable devices, including any new ones they buy. That' ... (view more)

The end of brick-like chargers that only fit one laptop is a step closer. The first USB cables that can carry up to 240 watts of power are now in production. For many years, one of the biggest drawbacks of laptops was the charger. In most cases they ... were considerably thicker than the laptop itself. They were also usually specific to the device (both in the plug/socket size and in the specific amount of power delivered). That meant somebody who lost or broke their charger would often face delay and expense before they could charge their device again. Things got a little better with the ... (view more)

Dell says its computers will soon be able to use two internet connections at once. Supposedly this will significantly increase speeds and reduce glitches, but the details are somewhat vague. It's part of a series of features packaged as Dell ... Optimizer aimed particularly at people using laptops for work while at home or on the move. They include an onlooker detection that appears to use the webcam to spot when somebody could be looking over the user's shoulder. Depending on the settings, the screen can then lock or blur. Another feature uses a combination of user settings and automated ... (view more)

A new form of computer memory could cut costs and storage space. "UltraRAM" would combine storage and memory on a single unit. Historically computers have always had to use separate units for memory (which is only needed temporarily) and file ... storage (which needs to be available until intentionally deleted or altered). As a rough analogy, file storage is like a filing cabinet, while memory is more like an in-tray, holding information to hand for quick access during the current task. Today many machines use flash memory for both RAM (the main memory on a PC) and solid state drives (a quicker ... (view more)
