“The Singularity” is a term coined by John von Neumann, a major figure in the history of computer science. The concept refers to a hypothetical time when computers become more intelligent than humans and can improve themselves without our input. Imagine a run-away reaction where artificial intelligence is able to improve itself. This improved self is able to further improve itself. With each improvement the rate at which…
Artificial intelligence holds tremendous promise, but the technology also threatens society. According to MIT Economist Daron Acemoğlu, AI must be regulated now.
The aviation pioneer Bell unveils a new type of eVTOL with high speed, also called HSVTOL, that can fly at 450 mph.

Due to the very limited availability and the high price of this card, there are not actually that many pictures of CMP 170HX on the Internet. Fortunately, Linus was brave enough to take a look under the card’s hood. As it turns out, the GPU has a very large heat spreader completetly covering the whole interposer area.
Researchers have uncovered details of new vulnerabilities in MediaTek’s audio DSP chips embedded in 37% of all smartphones and IoT devices.
More than 9 million Android phones are infected with malware distributed through Huawei’s AppGallery Store.
Apple has filed a federal lawsuit against Israeli spyware firm NSO Group for illegally targeting users with the Pegasus malware.
A now-patched vulnerability affecting Oracle VM VirtualBox could be potentially exploited by an adversary to compromise the hypervisor and cause a denial-of-service (DoS) condition.
“Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox,” the advisory reads. “Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DoS) of Oracle VM VirtualBox”
Tracked as CVE-2021–2442 (CVSS score: 6.0), the flaw affects all versions of the product prior to 6.1.24. SentinelLabs researcher Max Van Amerongen has been credited with discovering and reporting the issue, following which fixes have been rolled out by Oracle as part of its Critical Patch Update for July 2021.
The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.
One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.
Today, most frequency shifters are either too inefficient, losing a lot of light in the conversion process, or they can’t convert light in the gigahertz range, which is where the most important frequencies for communications, computing, and other applications are found.
