A massive optical computer being built could outpace quantum computers

New Scientist

The device, which is being built by Hiroyuki Tamura and colleagues at Japanese tech firm NTT, is specially designed to solve optimisation problems.


Scientists prove it's possible to build a DNA computer

#artificialintelligence

Current computers use a finite number of processors to perform these sorts of operations. A device that uses DNA molecules can grow more of itself to perform many calculations simultaneously, seemingly without limit. Quantum computers, still in their infancy, can also process concurrently, but still need specific set ups to do so, which limits their usefulness. DNA computers have no such constraint. "Imagine a computer is searching a maze and comes to a choice point, one path leading left, the other right," Professor King told Popular Mechanics, "Electronic computers need to choose which path to follow first.


Mini computers that fit in the palm of your hand

ZDNet

Want a computer that doesn't take up a good sized chunk of your desk? Here are a selection of PCs running a variety of operating systems -- Windows, Linux, Android, and Mac -- with price tags and system specifications to suit all needs. All the above computers are small enough that you can hold them in your hand, and many offer features such as fanless cooling and the ability to be used for embedded projects.


HP computer stranded in space

#artificialintelligence

Two HP servers sent up to the International Space Station in August 2017 as an experiment have still not come back to Earth, three months after their intended return. Together, they make up the Spaceborne Computer, which operates on the open-source Linux system and has supercomputer processing power. They were sent up to see how durable they would be in space with minimum specialist treatment. After 530 days, they are still working. Their return flight was postponed indefinitely, after a Russian rocket fail in October 2018.


Apple at 40: Seeing promise in the 'blossoming' home computer market

PCWorld

When Apple launched the Apple II in 1977, it was still far from certain that consumers would want or need a home computer. While hobbyists were tinkering with computers they built and programmed themselves, Apple saw a need for something easier, and introduced the Apple II. This article, republished from the May 1, 1978, edition of Computerworld, sets the scene at the time and describes how a young Apple Computer was looking to the future. CUPERTINO, Calif.--As soon as low-cost computers were available in configurations designed for use by consumers, with programming features and language that non-technicians could use, the personal computing market began to grow rapidly, according to Apple Computer, Inc., one of the firms vying for a share of that blossoming market. With more than 100,000 units sold, the personal computer market is finally being recognized as much larger then the original hobby market, a spokesman stated, observing that there have already been forecasts of 2 billion in sales by 1985.
