Heads up. Don't submit to CRAN right now. The CRAN submission system is currently broken, because Windows checks won't complete. If you submit your package will end up in the manual "inspection" queue. You'll see the same on win-builder R devel and R 4.6.1. The R 4.5.3 still works. #RStats

Forget about frontier lab model releases, the biggest launch of 2026 is this redesign of example.com. May very well be the launch of the decade.
Screenshot of the website example.com. Dark text on a light gray background. The text reads "This domain is for use in documentation examples without needing permission. This is not a service, avoid relying on it for testing and monitoring purposes.

TIL the new SQL cells on Observable support not just databases but variables defined in your notebook _and_ they output Arrow Tables which can be fed back into SQL cells: observablehq.com/@amoeba/sql-.... Nice.

This release is cool for a lot of reasons but my favorite is that the new Observable does database access with ADBC and returns results as Arrow. And, as a bonus, it uses @columnar.tech 's dbc (dbc.how) to install drivers.

My favorite Safari feature is how it auto-completes the URL you want to go to and then, mere milliseconds later, gets shy and removes the auto-completion, so my Google history is filled with a bunch of insane searches for two- and three-letter prefixes.

Apparently 14 years ago today I was in the village of Emmonak on the Yukon River taking pictures with a GoPro at 7:30 PM with the sun still high in the sky. This trip by itself was an incredible experience but so has the last 14 years.
Landscape photo taken with a wide FOV (GoPro). In the foreground lies a partially piled up gill net with visible floats, the webbing trailing off into the midfield. Scraggly trees make up the remainder of the midfield. In the background lies a stretch of the Yukon River delta with various minor islands behind. The sun is high in the frame and shines partially obscured by a mix of cumulus and stratus clouds. Some areas of blue sky are visible.

This week we announced a new ADBC driver for Apache DataFusion. DataFusion is Rust-native, but now you can use it from 10+ other languages through the same zero-copy Arrow ADBC interface that connects to 30+ other databases and query engines. Learn more: docs.adbc-drivers.org/drivers/data...
DataFusion logo centered on a white background with radial lines connecting it to language logos for Python, JavaScript, TypeScript, Go, Java, C#, C++, Rust, Ruby, R, and Kotlin.
