The Human Occupied Vehicle named Alvin

Yesterday a nurse told me about a Human Occupied Vehicle named Alvin. which, among many other things, made twelve voyages to the Titanic. You can read the basics here, and more here at noaa.org.

A quote from the first article: “Currently rated to 4,500m, which gives researchers in-person access to about 2/3 of the ocean floor, the most recent upgrade increased the depth rating of many of the vehicle’s systems, making it just steps away from having a depth rating of 6,500m, or approximately 98% of the seafloor.”

Writing at the beach

I’ve made some good progress on my new book on Scala and functional programming recently. For whatever reason I had been having writer’s block, so I came out to the beach for a little while to help clear out my brain, and today in particular was very productive. For a while now I’ve known how the book would end, but I was having a problem getting from where I was to the end, and I got through most of that today.

In a slightly related note, here’s a blurry photo of a military ship out on the ocean.
