Scientists have developed a method of measuring heart rate through wifi, bypassing the need to wear any equipment on your body. It works by filtering our noise and detecting the change in signal amplitude between heartbeats. https://spectrum.ieee.org/wi-fi-signal-heartbeat-detection?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline

Scientists have found a simple way for any conventional smartphone camera to serve as a hyperspectral sensor, reporting what molecules are in its photo. Identifying chemicals present in photos could be used in medical diagnostics, distinguishing authentic versus counterfeit products, monitoring air quality, and non-destructive analysis of pigments in artwork. https://spectrum.ieee.org/hyperspectral-imaging?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline

Computer #programming is, at its core, creative. If you’ve lost your spark, try checking out one of Daniel Temkin’s 44 esoteric coding languages. It’s not about making sense, it’s about stretching the limits of what a programming language can be, and what a community of programmers can do together. https://spectrum.ieee.org/esoteric-programming-languages-daniel-temkin?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline
