Physicist Uses Regular Digital Camera to Photograph A Single Atom

http://www.iflscience.com/physics/physicist-uses-regular-digital-camera-to-photograph-a-single-atom/ In 2012, Australian physicists captured the first image of a single atom. The process was painstaking and required a super-high resolution microscope. A new photograph taken by Oxford University physics PhD candidate David Nadlinger using only an ordinary digital camera shows a single, glowing-blue strontium atom hovering within a powerful vacuum chamber. It earned →

Computing at the Edge of IoT – Google Developers – Medium

https://medium.com/google-developers/computing-at-the-edge-of-iot-140a888007b We’ve seen that demand for low latency, offline access, and enhanced machine learning capabilities is fueling a move towards decentralization with more powerful computing devices at the edge. Nevertheless, many distributed applications benefit more from a centralized architecture and the lowest cost hardware powered by MCUs. Let’s examine how hardware choice and use case →

High-speed digital: 112 is the new 56 | EDN

https://www.edn.com/design/test-and-measurement/4460312/High-speed-digital–112-is-the-new-56 EDN magazine reports that at DesignCon 2018, 112 Gbps was all over the conference and exhibit hall. Even just a year ago, engineers were still talking more about 56 Gbps speeds than 112. This year, all agree that 56 Gbps speeds have been achieved. It’s time to move on. OIF-CEI 4.0, which included clauses →
