These alien-like creatures are virtually invisible in the deep sea.

Ivan Smirnov, Leading Research Fellow of the Laboratory of Computational Social Sciences at the Institute of Education of HSE University, has created a computer model that can distinguish high academic achievers from lower ones based on their social media posts. The prediction model uses a mathematical textual analysis that registers users’ vocabulary (its range and the semantic fields from which concepts are taken), characters and symbols, post length, and word length.

Every word has its own rating (a kind of IQ). Scientific and cultural topics, English words, and words and posts that are longer in length rank highly and serve as indicators of good academic performance. An abundance of emojis, words or whole phrases written in capital letters, and vocabulary related to horoscopes, driving, and military service indicate lower grades in school. At the same time, posts can be quite short—even tweets are quite informative. The study was supported by a grant from the Russian Science Foundation (RSF), and an article detailing the study’s results was published in EPJ Data Science.

Foreign studies have long shown that users’ social media behavior—their posts, comments, likes, profile features, user pics, and photos—can be used to paint a comprehensive portrait of them. A person’s social media behavior can be analyzed to determine their lifestyle, personal qualities, individual characteristics, and even their mental health status. It is also very easy to determine a person’s socio-demographic characteristics, including their age, gender, race, and income. This is where profile pictures, Twitter hashtags, and Facebook posts come in.

Circa 2019

NASA’s X-Plane Program has been around for 70 years. Over the course of those decades, the agency has developed a series of airplanes and rockets to test out various technologies and design advances. Now NASA has cleared the newest one, the X-59, for final assembly.

The X-59 is a supersonic aircraft design. Its full name is the X-59 Quiet SuperSonic Technology (QueSST) aircraft. Rather than pushing for greater speeds or higher altitudes like some previous X-Plane’s, the X-59 is designed to break the sound barrier without the sonic boom. The X-59 will produce no more than a loud thump, if anything at all, when it passes the sound barrier.

Circa 2014 o,.o.

IBM has started to flex its muscles with the Watson super computer after launching its software defined storage options for the big data era.

Seagate’s first HAMR drives will feature a whopping 20TB capacity when they debut later this year.

The experimental aircraft has completed 31 flights so far.

This craft uses laminar flow 😃

Aviation startup Boom Supersonic has unveiled a fully assembled version of its demonstrator aircraft, taking an important step forward in its efforts to build the world’s fastest airliner. The company’s XB-1 is a sleek, one-third-scale prototype of its Overture passenger plane, and is designed to break the sound barrier itself with test flights due to kick off next year.

Austrian company Cyclotech is planning to begin flight-testing an 80-kg (176-lb) demonstrator of its unique electric VTOL airframe, which uses Voith-Schneider propellers instead of rotors for exceptional agility and control in the air.

The prop design, which looks a bit like it belongs on the back of an 1850s paddle steamer, was patented nearly 100 years ago but hasn’t made it into a production aircraft yet. Each prop is a spinning cylinder whose walls are formed by a number of wing blades.
