Interesting things I've bookmarked (old posts, page 77)

Boston Dynamics: Handle

Handle is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4​ ​feet vertically. ​It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. ​​​Handle uses many of the same dynamics, balance and mobile manipulation principles​ found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere: by combining wheels and legs Handle can have the best of both worlds.

design patterns for humans

In software engineering, a software design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve a problem that can be used in many different situations.

What Historians Wish people Knew About Drugs

All of this leads to my final big point: “drug problems” are really “society problems.” Consider the current opiate crisis. Do you know when authorities in Ohio, where I reside, became convinced that Ohio had an opiate problem? When opiate deaths began to approach, and then surpassed, the number of car crash deaths in a year. This raises an important question: why are we so tolerant of car-crash deaths, so much so that their frequency has become our baseline for unacceptable accidental death in America?
