Before the next museum fire, make 4K video of all your documents

There are special machines for this but it's easy to make your own setup.

Many of you will have read of the tragic fire which destroyed the National Museum of Brazil. Many of the artifacts and documents in the museum were not photographed or backed up, and so are destroyed forever.

Tons of new ideas in aviation. Will regulation stop them?

XTI hybrid-electric VTOL design

This week I attended the "Revolution.Aero" conference on advanced new ideas in aviation, including electric VTOL aircraft (often called "flying cars.") I learned that there's a lot of interesting new stuff going on in aviation, but the strong regulatory environment keeps much of it repressed.

Waymo's left turns frustrate other drivers

This week's hot story was again from Amir at The Information and there is even more detail in the author's Twitter thread.

The short summary: Amir was able to find a fair number of Waymo's neighbours in Chandler, Arizona who are getting frustrated by the over-cautious drive patterns of the Waymo vans. Several used the words, "I hate them."
