Supply Chains have always been a critical differentiation to businesses. With the digital speed and pandemic situation, supply chain technologies have become more critical. This reflects in Panasonic’s proposed acquisition of U.S. supply-chain software firm Blue Yonder (formerly JDA Software) for $7.1 Billion.

Manufacturers and retailers have to manage global supply chains with significant agility given the pandemic disruptions, geo-political dynamics, digital speed of innovation, consumer choices, and varying demand. Edge, AI, and Blockchain, in addition to traditional planning, forecasting, visibility, and transactional systems, are driving innovation in supply chain technologies.

NASA’s Perseverance landed safely on Mars. It carried onboard a drone helicopter, Ingenuity. Ingenuity is the first vehicle to ever fly in another world. Given that it is 11 Light Minutes from Earth, Ingenuity needs to navigate autonomously to collect samples and perform other activities.

NASA’s Jet Propulsion Laboratory has open-sourced its F’ framework (pronounced F prime). Additionally, there are over 58 open source components, from Linux to simple utilities used in Ingenuity.

Some interesting observations:
