The rapid pace of technological change is clearly visible, but much of what you may not see, the exceedingly small physical components of change called nanotechnologies, are catalyzing the revolution.
Over 3.6 million MySQL servers are publicly exposed on the Internet and responding to queries, making them an attractive target to hackers and extortionists.
Of these accessible MySQL servers, 2.3 million are connected over IPv4, with 1.3 million devices over IPv6.
While it is common for web services and applications to connect to remote databases, these instances should be locked down so only authorized devices can connect to them.

Two-dimensional (2D) surface profiling systems are the standard for quality assurance in manufacturing, but some applications demand 3D measurement systems.

“In the beginning,” as some might say, an experienced machinist would use a scratch pad and an educated fingernail to determine the surface quality of a part. Then, in the 1940s, the first series of electronic surface finish gages were developed. Today, machinists and quality labs have surface finish standards and parameters and a variety of gages to measure surfaces.
There are two basic varieties of surface finish gage: skid-type, or averaging systems and skidless, or profiling systems. Skidded gages have a hinged probe assembly, with the probe riding next to a relatively broad skid that also contacts the workpiece. The skid tends to filter out waviness, so the probe measures only short-wavelength variations. A skidded gage usually has a dial or LCD readout to display the measurement as a single numerical value.

DeLorean has officially unveiled its upcoming electric adaptation of the 1981 DMC, the Alpha5.
The animals that inhabit these arid regions are already suffering the consequences. For example, earlier research has shown that multiple bird species are breeding earlier and for a shorter amount of time, impairing their reproductive success.
“There is rapidly growing evidence for the negative effects of high temperatures on the behaviour, physiology, breeding, and survival of various bird, mammal, and reptile species around the world,” said first author Dr Nicholas Pattinson, of the University of Cape Town. “For example, heat-related mass die-off events over the period of a few days are increasingly being recorded, which no doubt pose a threat to population persistence and ecosystem function.”
The southern yellow-billed hornbill’s distribution includes most of southern Africa, with a large portion falling within the Kalahari Desert. Known for its peculiar breeding and nesting strategy, the bird is a socially monogamous species. They are cavity nesters; the female seals herself into the nest cavity and stays there for an average of 50 days to brood and care for chicks, with only a narrow vertical slit for an opening, through which the male feeds the female and chicks.
Do you think that crimes committed within the Metaverse should be accountable just as the same as crimes accounted for in the “real” world?
A researcher entered the metaverse wanting to study users’ behavior on Meta’s social-networking platform Horizon World. But within an hour after she donned her Oculus virtual-reality headset, she says, her avatar was raped in the virtual space.
“Metaverse: another cesspool of toxic content,” a new report published by the nonprofit advocacy group SumOfUs on Tuesday, details the researcher’s violent encounter in Meta’s Horizon World.
