Engineering Ethics Blog: Our Unelected Big-Tech Overlords

  Last week I blogged about how Twitter kicked off @realDonaldTrump, and how decisions like that give the lie to Twitter’s claim of common-carrier-like protection against lawsuits granted by Section 230 of the Communications Decency Act.  Normally I like to change topics every week, but this week is an exception.    A week ago today, on Jan. 10, Amazon Web Services shut down its web-hosting services for the social-media network Parler, taking it off the Internet and capping a series…

UC Berkeley conservationist discovers the first evidence of visual communication among tropical glass frogs — ScienceDaily

Most frogs emit a characteristic croak to attract the attention of a potential mate. But a few frog species that call near loud streams — where the noise may obscure those crucial love songs — add to their calls by visually showing off with the flap of a hand, a wave of a foot or a bob of the head. Frogs who “dance” near rushing streams have been documented in the rainforests of India, Borneo, Brazil and, now, Ecuador. Conservation…

Uganda’s January 13, 2021 Internet Shut Down

Two days ago, through its communications regulator, Uganda’s government ordered the “Suspension Of The Operation Of Internet Gateways” the day before the country’s general election. This action was confirmed by several users and journalists who got access to the letter sent to Internet providers. In other words, the government effectively cut off Internet access from the population to the rest of the world. Ahead of tomorrow’s election the Internet has been shutdown in Uganda (confirmed by a few friends in…

COVID Vaccine Moves to the Front of the Supply Chain

This article appeared in Electronic Design and has been published here with permission. What you’ll learn: How does the rapid-response detection unit work? What components were used to create the RapidPlex unit, and how was it built? It would be a major advance if there was a basic test instrument or front end that could determine if someone harbors the COVID-19 virus—and soon that might be a reality. A team at the California Institute of Technology (Caltech) has developed a…

A Name Resolver for the Distributed Web

The Domain Name System (DNS) matches names to resources. Instead of typing 104.18.26.46 to access the Cloudflare Blog, you type blog.cloudflare.com and, using DNS, the domain name resolves to 104.18.26.46, the Cloudflare Blog IP address. Similarly, distributed systems such as Ethereum and IPFS rely on a naming system to be usable. DNS could be used, but its resolvers’ attributes run contrary to properties valued in distributed Web (dWeb) systems. Namely, dWeb resolvers ideally provide (i) locally verifiable data, (ii) built-in…

Micro Hypervisor Targets Automotive Microcontrollers

>> Electronic Design Resources.. >> Top Stories of the Week.. .. >> CES 2021 Anyone who has read Ray Bradbury’s A Sound of Thunder or Eric Flint’s 1632 series knows about the Butterfly Effect. This is where small perturbations, like the flap of a butterfly’s wings, affects changes years later and far away. 2021 has had a lot of big butterflies these days, starting with general upheavals from Brexit to COVID-19 to attacks on the U.S. capitol and massive security…

Wives bore the brunt of child care during the shutdown — ScienceDaily

Traditional gendered patterns of child care persisted during the COVID-19 shutdown, with more than a third of couples relying on women to provide most or all of it, according to a study from University of Georgia researcher Kristen Shockley. Some previous research has found that typical familial patterns may get upended during crises, but that’s not what Shockley and her colleagues found in the early months of the COVID-19 shutdown. “Most people have never undergone anything like this before, where…

Why V2X Should Start with Two-Wheelers

What you’ll learn: What’s causing V2X’s slow adoption? Stats showing that bicycles and eScooters are actually much more dangerous. Adding V2X beacons for greater safety.   Vehicle-to-everything (V2X) communication connects vehicles to other vehicles (V2V), infrastructure (V2I), motorcycles (V2M), and pedestrians (V2P) within wireless range for safety and mobility applications. It adds a new layer of confidence and certainty for drivers as it helps prevent car accidents. However, the gap between V2X’s ability to enhance road safety and its slow…

Cloudflare Radar’s 2020 Year In Review

Throughout 2020, we tracked changing Internet trends as the SARS-Cov-2 pandemic forced us all to change the way we were living, working, exercising and learning. In early April, we created a dedicated website https://builtforthis.net/ that showed some of the ways in which Internet use had changed, suddenly, because of the crisis. On that website, we showed how traffic patterns had changed; for example, where people accessed the Internet from, how usage had jumped up dramatically, and how Internet attacks continued…

Boosting a natural cellular process could reduce damage, study suggests — ScienceDaily

An unfortunate truth about the use of mechanical ventilation to save the lives of patients in respiratory distress is that the pressure used to inflate the lungs is likely to cause further lung damage. In a new study, scientists identified a molecule that is produced by immune cells during mechanical ventilation to try to decrease inflammation, but isn’t able to completely prevent ventilator-induced injury to the lungs. The team is working on exploiting that natural process in pursuit of a…
