I had no idea so many countries didn't have a well established highest point! These two brothers have apparently found 7 new country high points. So far, Gambia, Saudi Arabia, Uzbekistan, Togo, and Guinea-Bissau, with Botswana and Colombia pending peer review.

Uh oh, saw a very plausible N+1 bike for sale used in town. Much cheaper than new options I was looking at for steel frame, flat bars, rigid front fork, big tires. It hits my niche for a little more than gravel, a little less than an XC mountain bike, adventure bike. Very tempted!

Kilauea is putting on a spectacular show right now. Huge gouts of lava spewing high into the air. The USGS has several live cameras watching it and camera 3 was taken out by the lava fall. If you scrub back in time you can watch as the rain of molten rock creeps forward and “Pompeiis” the camera […]

I was starting to think my temperature sensor was offline, but no, the temperature really has been nearly constant over the past 3 days, hovering right around freezing.

I find it incredibly sad and lame that Google's latest AI product release has stolen the name of an XKCD comic about restoring joy to programming (without attribution, as far as I can tell) for something that destroys joy, and creativity.

I am on my way home to Toronto and the aurorae are absolutely phenomenal.
If you are anywhere in the northern half of the continent, get outside and look up! Or better still, put your camera on a 10 second exposure and point it up.
