In osrm.backend v0.3, I am sharing more improvements that I made for myself with the R community: improved handling of multiple OSRM servers running in parallel, support for latest v26 of OSRM binaries and also brand new shiny app GUI based on `mapgl` www.ekotov.pro/osrm.backend/ #rspatial #rstats

Great to see person-centered pages on the new R observatory! Love the frequent collaborators section in those, and especially the collaborator network view! See mine at r-observatory.thecoatlessprofessor.com/authors/Egor...

Checking on an R package usually takes five open tabs: CRAN, GitHub, download counts, reverse deps, check results. R Observatory collects all of that on one page, for every CRAN and Bioconductor package. r-observatory.thecoatlessprofessor.com #rstats

🚨 Good news for #OpenStreetMap folks: new #pyrosm is out after a long break! 🥳 pyrosm reads PBF files efficienty into #geopandas GeoDataFrames. You can parse buildings or street networks for whole countries. Here, we extracted all buildings from South America in 3.5 mins. More below 🧵👇

#rstats mapgl is now on CRAN with flowmaps support! As previewed at #MobileTartu (Mobility Lab, University of Tartu) and Association of Geographic Information Laboratories in Europe (#AGILE) conferences!

Animated, hierarchical origin-destination commute flows in Dallas-Fort Worth, TX. Downtowns, medical districts, airports, and suburban job hubs light up from 2023 LODES data. Now available in R's mapgl 0.5.0. Credit to @ekotov.pro for the implementation and @ilyabo.bsky.social for Flowmap.gl!

The upcoming v0.5 release of mapgl for #rstats is going to be massive. Included: a slider control that allows for interactive data filtering - no Shiny required. Thanks to @ekotov.pro - brush a window over a histogram, see your data filter in real-time Lots more examples to share this week

Still quite a few holes, but apache.r-universe.dev/sdplyr is in the works!

sdplyr: Apache SedonaDB 'dplyr' Interface

Provides a 'dplyr' backend implemented using 'SedonaDB'.

🕵️‍♂️ Is your privacy filter model being "distracted"? I tried the new #OpenAI Privacy Filter 1.5B MoE model. ✅ "Alice password is LastOcean123" -> 100% conf LastOcean123 is a password ❌ "Alice Trump password is LastOcean123" -> 0.19% conf LastOcean123 is a password See thread 🧵👇

In 2024 I spent days trying to optimize a point-in-polygon join with ~130 million points against all U.S. zipcodes and the best I could come up with was a few minutes. In 2026, both SedonaDB and @duckdb.org spatial can both do it in seconds 🤯. More in the post! dewey.dunnington.ca/post/2026/wr...
