Exocortex: Thought this might be of some interest
Posted by Dan Breeden in categories: biological, computing, neuroscience, transhumanism
An is an external information processing system that augments the brain’s biological high-level cognitive processes.
An individual’s would be comprised of external memory modules 0, processors 0, IO devices and software systems that would interact with, and augment, a person’s biological brain. Typically this interaction is described as being conducted through a direct brain-computer interface 0, making these extensions functionally part of the individual’s mind.
Individuals with significant exocortices can be classified as transhuman beings.

An indium oxide-based transistor created using atomic layer deposition
Posted by Dan Breeden in categories: computing, mobile phones, solar power, sustainability
Over the past decades, engineers have created increasingly advanced and highly performing integrated circuits (ICs). The rising performance of these circuits in turn increased the speed and efficiency of the technology we use every day, including computers, smartphones and other smart devices.
To continue to improve the performance of integrated circuits in the future, engineers will need to create thinner transistors with shorter channels. Down-scaling existing silicon-based devices or creating smaller devices using alternative semiconducting materials that are compatible with existing fabrication processes, however, has proved to be challenging.
Researchers at Purdue University have recently developed new transistors based on indium oxide, a semiconductor that is often used to create touch screens, flatscreen TVs and solar panels. These transistors, introduced in a paper published in Nature Electronics, were fabricated using atomic layer deposition, a process that is often employed by transistor and electronics manufacturers.

Russia now faces critical digital crisis with only limited time left
Posted by Kelvin Dafiaghor in categories: business, computing, economics, government
The Russian government is now facing a digital storage crisis as Western cloud services have pulled their services from the country.
Western cloud storage providers have pulled out of Russia following heavy Western sanctions designed to cripple the Russian economy. According to reports, the Russian government is looking at several different ways to solve the problem of finding hosts for Russia’s data, and some of those solutions include leasing all available data storage across Russia or seizing all data storage from Russian businesses that have left the country.

New Linux Bug in Netfilter Firewall Module Lets Attackers Gain Root Access
Posted by Saúl Morales Rodriguéz in categories: computing, security
A newly disclosed security flaw in the Linux kernel could be leveraged by a local adversary to gain elevated privileges on vulnerable systems to execute arbitrary code, escape containers, or induce a kernel panic.
Tracked as CVE-2022–25636 (CVSS score: 7.8), the vulnerability impacts Linux kernel versions 5.4 through 5.6.10 and is a result of a heap out-of-bounds write in the netfilter subcomponent in the kernel. The issue was discovered by Nick Gregory, a senior threat researcher at Sophos.

Creating sub-1-nm gate lengths for MoS2 transistors
Posted by Chima Wisdom in categories: computing, nanotechnology, particle physics
A team of researchers working at Tsinghua University in China has created a sub-1-nm gate in a MoS2 transistor. In their paper published in the journal Nature, the group outlines how they created the super tiny gate and explains why they believe it will be difficult for anyone to beat their record.
For most of the history of microcomputing, Moore’s Law has held up—researchers and engineers have managed to double the speed and capability of computers regularly by reducing the size of their components. But more recently, it has grown increasingly difficult to make components smaller as scientists now run into physical limitations. In this new effort, the researchers believe they may have bumped up against the ultimate limit—they have built a gate that is just one atom in length.
At their most basic, transistors are a source and a drain, with a gate controlling the flow of electricity between them. It switches on and off depending on how much electricity is applied. The push to reduce the size of the components has led to the testing of materials such as carbon nanotubes, which are approximately 1nm, for use as gates. In this new effort, the researchers have unrolled the carbon nanotube and used its graphene edge as the gate—reducing its length to just 0.34 nm.
