Hi all! A (re)-introduction: I'm Tyler, developer of #rayshader and the #rayverse, a collection of R packages for 3D #dataviz and #mapping.
Here's one of my greatest hits (now that Bluesky supports videos!): The Earth's submarine fiber optic cable network, visualized in #RStats with #rayrender.

heads up that bluesky doesnt show posts from other languages by default on your timeline, and its cutting you off from a lot of the community
go to bsky.app/settings/lan... and deselect any language from this setting, or else you might not see any of the new japanese users at all!

If this same thing is ever an issue for someone on a Mac just shake the cursor real fast and it'll magnify it so you can find it. I use this constantly bc I have two monitors and also way too much on them.
For the past few years, I have occasionally have had trouble finding the mouse pointer on my monitor. I just chalked it up to getting older ("I guess it's all downhill from here!"). But recently, I found a feature in Windows that draws a circle around the mouse when you hit CTRL...

Numerically modeling reproduces the proposed effect of closed depressions and highlights the role of depression breaching by gullies in the ultimate destruction of the tablelands, also observed in the real landscape (animation of one scenario, 3D perspective view with the help of #rayshader). 4/5

North Platte valley and tablelands to the south, western Nebraska. Tried to shade it to represent both varying vegetation cover and the colors of rock and sediment exposed on steeper slopes, stylistically, not super accurately. Lower bench above the floodplain is underlain by the Ogallala Grp... 1/2

10 years of learning R and I'm always learning (i.e. banging my head against) new things: today's fun fact is that the code in .Rprofile is run **before** loading any of the default libraries, so stats::filter actually overrides dplyr::filter for once! Thanks for the confusing 5 minutes, #RStats.👍

Still working on the Bighorn Mountains, Wyoming, now draped with units and approximate colors from the Love and Christensen Geologic Map of Wyoming. View from high above the Bighorn Basin. Next steps a legend or labels, I guess, and trying out different viewpoints & z factors. #rayshader #rayrender

i dont want to live in a world that values gambling apps and ai i want to live in a world that celebrates mustard and puppets
This commercial for French's Mustard from 1987 is equal parts charming and also kinda unsettling, but what strikes me is the work that went into the absolutely delightful puppetry and practical effects for a *mustard commercial*!! Imagine that today??

Ships of the Gulf of México. Thought I'd try to overlay all of them on one viz this time. Probably clearer if I split them up, no?

Yea, this only occurs in RStudio. In RStudio, it's "one shot" as you said. To RStudio, the whole file changed out from under it, so when you undo, you replace the whole file.
To Positron, or any other LSP backed implementation, air sends over _edits_ that the IDE uses to actually modify the file.

Is there a "jump to last edit" keyboard command in RStudio or Positron? I've been working in a 4000 line {targets} pipeline and I've taken to hitting "CTRL-Z" to undo my last edits simply because it also has the side-effect of jumping to that part of the document.
