http://www.sciencealert.com/people-who-pick-up-grammar-mistakes-jerks-scientists-find Scientists have found that people who constantly get bothered by grammatical errors online have “less agreeable” personalities than those who just let them slide. And those friends who are super-sensitive to typos on your Facebook page? Psychological testing reveals they’re generally less open, and are also more likely to be judging.  “This is the →

http://www.iflscience.com/brain/heres-how-your-beliefs-are-linked-to-different-types-of-science-denial/  There’s nothing wrong with being skeptical. There is, however, a difference between skeptical claims without substantial evidence to back them up, and being a skeptic on vaccines or human-driven climate change. Both are backed up by a gigantic mountain of facts, so why are certain groups of people still keen to rally against them? A new study →

Here is rebuild of simple oscilloscope art circuit using point-to-point construction on terminal strip: In is the circuit in use. Much more convient than loose parts on table. →

https://xeushack.com/the-art-of-human-hacking/ Now that we’ve been introduced to social engineering, it’s time to learn about the vulnerabilities in the system we’re trying to hack into: humans. Social engineering is all about making someone do something that they’re not supposed to do.  →

https://spectrum.ieee.org/view-from-the-valley/at-work/tech-careers/what-tech-skills-are-hot-react-cloud-or-not-linux-tableau  It’s a good time to have experience in React, the JavaScript library used to create user interfaces, according to a study released this week by job search firm Indeed.com. Meanwhile, a growing number of job seekers are touting their Linux skills, but employers are less interested. And Python’s status is, well, complicated, the Indeed study showed. →

https://spectrum.ieee.org/nanoclast/semiconductors/devices/mramlike-device-could-make-logic-run-backwards This is an interesting idea: Engineers at Purdue University and the University of California at Berkeley have discovered that a simple combination of commonly available devices creates a computing element that could lead to some truly strange circuits: logic that can perform its inverse operation. Some important aspects of modern computing—notably encryption—depend on there being →
