AI synthesizer bridges technology and creativity in music composition

Award-winning designer and artist Arvind Sanjeev has created his latest vision for music creators. SPIN, an AI music synthesizer, challenges conventional notions of music creation by inviting users to collaborate with an AI language model called MusicGen. With its distinctive blend of a turntable and a drum machine, SPIN offers users a creative music composition tool.At the core of SPIN are two essential components: the Raspberry Pi 4 Model B and the Arduino Mega 2560 microprocessors. These serve as the foundation of the…

Scientists Identify Composition of 2000-Year-Old Roman Perfume

Researchers from the University of Cordoba have, for the first time, identified the components of a 2,000-year-old Roman perfume discovered in a sealed vessel in Carmona, Spain. Chemical analysis revealed that the perfume, found in an affluent family’s mausoleum, was based on olive oil and contained patchouli, an Indian-origin scent previously unknown in Roman times.

The findings, which were published in Nature…

Webb Space Telescope Shocks Astronomers With Surprising Exoplanet Atmospheric Composition

Astronomers using NASA’s James Webb Space Telescope have discovered that the atmosphere of exoplanet HD149026b is super-abundant in the heavier elements carbon and oxygen – far above what scientists would expect for a planet of its mass, and the carbon-to-oxygen ratio is elevated relative to our solar system, which could provide insight into planet formation and an important first step toward obtaining similar measurements for a large sample of exoplanets in order to search for statistical trends.

Inheritance vs Composition: Using a Role-Playing Game in JavaScript as an Example

Inheritance Problems Duplication of code in children Excessive complexity in the inheritance hierarchy Changing the behavior of the parent can lead to errors in the children In this article, we will look at what these problems are about and how we can solve them using composition. the problem with object-oriented languages is they’ve got all this implicit environment that they carry around with them. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle. - Joe Armstrong, creator of…

Samsung Galaxy Watch 4/5’s body composition measurements are fairly accurate, study shows

Last updated: November 16th, 2022 at 07:56 UTC+01:00 Today, people are incorporating healthier lifestyles into their daily routines. One of the measurements of your physical form is your BMI. The BIA (Bioelectric Impedance Analysis) is a much better metric, though. It was previously only available in clinics and gyms, but can now be measured right from your wrist using the Galaxy Watch 4 or the Galaxy Watch 5. A team from Louisiana State University, Pennington Biomedical Research Center, and the University of Hawaii…
