Sprouts is a paper-and-pencil game that can be enjoyed simply by both adults and children. Yet it also can be analyzed for its significant mathematical properties. It was invented by mathematicians John Horton Conway (*that* Conway) and Michael S. Paterson at Cambridge University in the early 1960s./blockquote>

The creator of the YOLO object-detection algorithms has stopped computer vision research due to ethical concerns
‘The creator of the YOLO algorithms, which (along with SSD) set much of the path of modern object detection, has stopped doing any computer vision research due to ethical concerns.’Quite valid — most of the applications of CV have always been military, as far as I could tell.

Heavy-duty electric truck driver ditches diesel
This is significant news — sounds like electrified heavy trucks are well on the way:
When it is time to accelerate, the eCascadia’s single gear provides immediate power. That matters during all-too-frequent slowdowns on California freeways. When traffic begins moving, Williams keeps pace. In a diesel, he would be left behind, working through gears to get up to speed. “I would have the space of two diesel trucks in front of me. By the time I get going, five cars jump in front of me,” he said. “With this truck, I can stay right with the cars rather than being dropped back every time we stop and go.” Even with the truck restricted to 60 mph, Williams said he can shave 15 minutes off the drive from the ports to Chino in heavy traffic. With advanced driver assistance systems (ADAS) like adaptive cruise control, which keeps his truck at a set distance from the vehicle in front of him, and automatic emergency braking, Williams also drives a safer truck.
