https://www.realclearscience.com/lists/biggest_junk_science_2017/2017_worst_junk_science.html In a perfectly logical world, where everyone has adopted science as a way of thinking, lists like this wouldn’t be necessary. Unfortunately, as 2017 demonstrated, we’re nowhere close to that world as junk science is alive and seems to be thriving. →
A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. Packaged solid-state relays use power semiconductor devices such as thyristors and transistors. Here are some SSR videos worth to watch: What is a Solid State Relay? https://www.youtube.com/watch?v=wbQiRM9p0j0 Solid State Relay →
http://www.iflscience.com/health-and-medicine/scientists-may-have-found-the-root-cause-of-autism/ Scientists think they’ve found out what could be at the root of autism and, no, it’s not vaccines. According to a new study, it could be caused by having too many brain connections called synapses. “An increased number of synapses creates miscommunication among neurons in the developing brain that correlates with impairments in learning, although we →
https://blog.cloudflare.com/performing-preventing-ssl-stripping-a-plain-english-primer/ Article on SSL security. It is beyond doubt that it is simply not secure to blindly trust the medium that connects your users to the internet. HTTPS was created to allow HTTP traffic to be transmitted in encrypted form This blog post presents a plain-english primer on how HTTPS protection can be stripped and →
https://developers.redhat.com/blog/2017/10/12/new-api-pattern/?sc_cid=7016000000127ECAAY Distributed Architectures are a lot like neural networks; all services that talk to each other need to share the I/O in and in a way that they can synchronize that information on the fly. Since the API Pattern designed in the 1970’s for centralized architectures and NOT distributed architectures, it was never intended to →
https://spectrum.ieee.org/tech-talk/consumer-electronics/audiovideo/mit-shows-how-smartphones-could-peek-around-corners Magically seeing around corners to spot moving people or objects may not rank first in most people’s superhero daydreams. But MIT researchers have shown how they could someday bestow that superpower upon anyone with a smartphone. Their secret to peeking around corners is detecting slight differences in light patterns reflected from moving objects or →
Today is a special day: https://en.m.wikipedia.org/wiki/Friday_the_13th Friday the 13th is considered an unlucky day in Western superstition. It occurs when the 13th day of the month in the Gregorian calendar falls on a Friday, which can be the case at least once every year, and up to three times a year. The superstition surrounding this day may have arisen in the Middle →

That is why allowing the immediate and continuous exchange of binary data has made the full-duplex bus the preferred interface choice in point-to-point connections. The world of RS-485 users is seeing →
