Carriers are fully in the swing of deploying their 5G networks , with AT&T , Verizon , and T-Mobile all having now rolled out nationwide networks using a combination of Sub-6 and mmWave spectrum . That’s good news for those who want to enjoy 5G on their smartphones — but it may have an impact on another internet connection too: the home internet connection. Along with massively supporting mobile 5G , carriers are also beginning to launch 5G home internet services, sometimes called fixed wireless . These services basically involve the use of a gateway, which connects to your carrier’s 5G network and turns that signal into Wi-Fi for your home devices. Here’s everything you need to know about the 5G home internet plans currently on offer. Verizon 5G home internet Verizon’s 5G home internet service is currently the most robust in the U.S. The company has been pushing a 5G Home Internet service of one flavor or another since late 2018, and while it’s available in … [Read more...] about 5G home internet: Carriers, coverage, and plans

In the 1990s, there was a strange trend where two movies about the same topic came out in the same year. For example, Volcano and Dante’s Peak , both movies about killer volcanos, hit theaters in 1997. The next year, in 1998, both Deep Impact and Armageddon were about heavenly bodies crashing into Earth. This trend perhaps reached its zenith the next year, in 1999, with two movies about the idea that we live inside a video-game-like world: The Matrix and The Thirteenth Floor . In the years since, the idea that we might be living inside an ultrarealistic simulation — known as the simulation hypothesis — has moved from pure science fiction to serious speculation among scientists, philosophers, and academics. In fact, when I released my book, The Simulation Hypothesis: An MIT Computer Scientist Shows Why AI, Quantum Physics and Eastern Mystics Agree We Are in a Video Game , I chose an auspicious date: March 31, 2019, exactly 20 years from the day that The Matrix hit … [Read more...] about 22 years after The Matrix, simulation hypothesis movies are booming again
Ethereum mining is most profitable on high-end graphics cards, but enthusiasts are often willing to use whatever they have on-hand, especially as the cryptocurrency’s value continues to rise. Now they’ll have another option: Apple’s new M1 chip. Zensors software engineer Yifan Gu found a way to make the ethminer utility run on a MacBook Air featuring the M1 processor. It required a bit of setup, but Gu made the code available on GitHub, so curious Mac owners can check it out themselves. This isn’t the first time someone’s used the M1 for mining. CryptoAge reported in December 2020—just one month after the first Macs featuring the chip debuted—that XMRig’s developers had experimented with mining the Monero cryptocurrency. The experiments yielded similar results. Gu said the MacBook Air could only mine Ethereum at roughly 2MH/s; CryptoAge said the M1 offered similar performance mining Monero. This would lead to profits equivalent to just $0.14 of daily profitability … [Read more...] about You Can Mine Ethereum With Apple’s M1: Here’s How, but You Probably Shouldn’t Bother
How do urban planners and building developers cope as more and more people move to cities? There are a few things they might do. To begin with, they could physically make the city larger, widening its borders to cover surrounding land so as to accommodate more houses. They might also build houses closer together, squeezing more single- and double-story buildings onto each street. At a certain point, however, there’s really only one option: You build upward by creating tower blocks that can house hundreds on a patch of land that would otherwise fit only a tiny fraction of that number. This, in essence, is a similar problem to the one faced by chip designers. Moore’s law states that, every couple of years, the number of components that can be inexpensively crammed onto an integrated circuit doubles. The power of Moore’s law is undeniable. In 1971, for example, Intel released the 4004 , the world’s first commercially available microprocessor, packing 2,300 transistors onto a single … [Read more...] about Moore’s law is reaching its limits. Could graphene circuits help?
