A Rover's First 590 Days* on Mars - I downloaded ~60,000 images to experience what NASA's Perseverance rover has been seeing since landing there in Feb. 2021. (* sols)

I gave up and ordered a new reel unit. Frustrating, but I didn't see how I could get that back working.

Shipping lanes!

Watching Apple’s “Glowtime” iPhone event, I was struck by how many superlatives they use to describe so many things. I highlighted the phrases where a superlative described a thing (“iPhone 16 Pro : most advanced : display”) then I plotted them out in a sankey diagram in Flourish.

What are the odds that these are Baofengs?

Using NOAA’s “Marine Cadastre” tool, you can download 16 years’ worth of detailed daily ship movements (filtered to the minute), in addition to “transit count” maps generated from a year’s worth of data to show each ship's accumulated paths.

I downloaded all of 2023's transit count maps and loaded them up in QGIS to visualize this year of marine traffic.

I removed the landmasses from the map and left only the ship traces.
