Quantum computers could be practical in just three years from now according to a manufacturer. The technology could transform the speed and capability of computers. Oxford Ionics says it has not only produced a quantum computer chip with twice the ... performance of any existing chip, but that it could mass-produce its new design without needing specialist facilities. The idea of quantum computing has been explored for many years and aims to overcome one of the biggest limitations of traditional computing. Ultimately existing computers simply store data as either a 0 or a 1 (a bit), usually ... (view more)

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)

Microsoft has released an optional Windows 10 update that could solve a recent problem with high CPU usage. Users who haven't had this problem can probably give the update a miss. The update, with the reference KB5001391 is optional as it's a "C ... release". That means it's made up of fixes and features that will roll out in the main update cycle later on but are available now as a preview. The main point of interest in KB5001391 is a fix for a memory problem. Microsoft hasn't made things entirely clear but it appears it's targeted at recent reports of users suddenly seeing their CPU usage ... (view more)

A serious shortage of processor chips is affecting the supply chain of computers and other electronic devices. It's caused by a combination of supply and demand changes. The problem has caused not just price rises but a lack of availability. Devices ... as diverse as the latest iPhone model, the PS5 games console and high-tech cars have all been delayed or in short supply. The Guardian reports that the problem is partly down to a backlog caused by chip production factories shutting down for social distancing reasons in the early stages of the pandemic. However, even as that clears, demand is ... (view more)

Google is experimenting with a way to make Chrome use less power when a laptop battery is starting to run out. But it will rely on website owners to make it happen. The test is of a "Battery-Savings Meta Tag" which can be added to a website's code ... and will include battery saving recommendations specific to that site. These would then kick in whenever the computer is at a particular battery level. The idea is to avoid having Chrome itself simply take blanket measures that might not be appropriate for all websites. Video Frame Rate Lowered One of the examples Google gives is for a tag to say ... (view more)

Chrome is to start automatically blocking online ads that make particularly high use of computer resources. It will be a small change that Google hopes will have a big effect. This will be the second set of changes Chrome has made to the way it ... handles ads following alterations over the past couple of years to block "abusive" and "deceptive" ads. These include ads which have misleading buttons such as a "play" button that actually downloads a file or a "close window" button that actually opens new pop-up windows. The new change will involve Chrome having an limit on how much resources such as ... (view more)

According to a recent report, Microsoft products made up eight of the ten most exploited software bugs last year according to a security company. That's higher than in recent years, largely because Adobe Flash is becoming a less rewarding target for ... hackers as it loses popularity. As recently as 2015, most of the top ten involved bugs with Flash. Microsoft took the unwanted lead in 2017 with seven entries on the list. (Source: bleepingcomputer.com ) Internet Explorer Tops The List The top spot for 2018 went to a bug in the Windows VBScript engine . That's a tool that handles code designed for ... (view more)

Google has developed a new type of encryption that could run on any Android device. It means added security even for the most basic phones, smart watches and smart TVs. The encryption in question isn't for transmitting data, but rather for data ... stored on a device. The data is controlled by unlock methods such as passwords, pin codes and fingerprints. The idea is that if somebody gets hold of a device and doesn't have the correct login credentials, they can't simply extract files from the device and access personal data. At the moment Android devices with encryption use Advanced Encryption ... (view more)

One of the most useful features in computer hardware has a security flaw. It's to do with the way processors handle information. All computing tasks are reduced down to a set of calculations. The central processing unit (CPU) is the "brain" of the ... computer that physically carries out these calculations. Each modern-day CPU has one or more cores , which is essentially multiple "brains" on a single CPU chip. A multi-core CPU means that multiple calculations can be done at once, which reduces the time to carry out a task. Many processors also use a technique called ... (view more)

Google is updating the Chrome browser to give it better defenses against major security threats. It comes at the price of reduced performance and a larger memory footprint. The changes are to address two security bugs labeled Meltdown and Spectre by ... researchers. They take advantage of a flaw in almost every computer processor built since 1995, which is (as of this day) 100% of all computers, tablets, smartphones, laptops - and anything else that uses a processor. The flaw is in regard to a processor feature, which is designed to speed up a computer's response time. It works by using spare ... (view more)
