Wandermap is a website with thousands of user-submitted hikes (and bike routes) all over the world. My favorite feature lets me draw a route on the map to see how far it is and the change in elevation along the route.

Half of our climate goals can be achieved by electrifying everything. This free book, Electrifying Everything in Your Home (PDF download), gives very explicit and useful instructions on how you can electrify your own home and life, even if you are a renter. Covers heat pumps, solar panels, electric vehicles, electric appliances, and more. It’s thorough. I found the section on electric heat pumps (which replace furnaces and air conditioners) particularly helpful because I could not find this kind of reliable actionable info anywhere else. — KK

At the end of the page there is a note of Ages: that rescales the timeline to a calendar year which is really interesting. The Big Bang begins on January 1, the Sun forming on September 1, earliest signs of life appear on September 13, and just 2 hours before the year’s end appears us — humans. — CD

My 18-year-old daughter bought an Oculus Quest 2 VR system but didn’t like it. It sat in the box for a few months before I gave it a try. I got a trial subscription to a boxing fitness program called Supernatural. I’m hooked. It’s so much fun that I don’t notice that my heart is beating fast and I’m panting as I’m dodging, ducking, and jabbing. With over 500 workouts, I look forward to the beautiful settings and enthusiastic coaches every time I work out. — MF
