In 1983, a Korean commercial airline, en route from Anchorage, Alaska, to Seoul, mistakenly entered the Soviet Union’s airspace. A Soviet fighter jet shot it down, killing 269 people. To minimize future navigational errors, President Ronald Reagan allowed civilian access to GPS. But that access came with a catch—to protect national security, he imposed a filter that blunted the accuracy, as compared to what was available to the military.
It’s been 50 years since the switch was flipped on American Beatlemania—perhaps the purest Beatlemania there ever was, certainly the most virulent—and torrents of analysis commemorate the occasion. Recently we have seen the publication of All the Songs, by Jean-Michel Guesdon and Philippe Margotin; The Beatles: The BBC Archives 1962–1970, by Kevin Howlett; and Tune In, the first volume, 900-plus pages long, of Mark Lewisohn’s projected biographical trilogy. But with no disrespect to these authors or their labors, if it’s a radical reexperiencing of the Beatles that you’re after, a refreshing of your Beatle-chemicals, there’s only one book you need.
Quantenna Communications, a high-performance Wi-Fi chipmaker, today announced that it is developing an 8×8 MIMO architecture with adaptive beamforming that promises significantly higher throughput. Using 8 receive antennas and 8 transmit antennas, Quantenna says up to 10 Gigabits/second are possible using their Wi-Fi chipset and 160 MHz channels.
Fear has a place in our emotional life, and it shows up daily. Everything causes it: finding new work, dealing with financial uncertainty, creating something new, contemplating failure. By necessity, our minds are designed to let fear in—without it, we’d never survive.
