New on CRAN: zarr (0.1.1). View at https://CRAN.R-project.org/package=zarr
zarr: Native and Extensible R Driver for 'Zarr'
The 'Zarr' specification is widely used to build libraries for the storage and retrieval of n-dimensional array data from data stores ranging from local file systems to the cloud. This package is a native 'Zarr' implementation in R with support for all required features of 'Zarr' version 3. It is designed to be extensible such that new stores, codecs and extensions can be added easily.

new package time! my new #rstats package {qrtdown} is sugar syntax version of {pkgdown} by @hadley.nz and {altdocs} by @etiennebacher.bsky.social but enables full quarto functionality for your articles

Thus you can use the full @quarto.org eco system and benefits.

Jeffrey Epstein’s brother Mark sent a tip to the FBI accusing Trump of authorizing his murder:

“I have reason to believe he was killed because he was about to name names. I believe Present Trump authorized is murder.“

Just quietly, there is an absolute sh*t tonne of great stuff on @thepointau.bsky.social right now.

Frontline services ‘trapped in crisis mode’ as housing emergency deepens
Frontline community services are being pushed to breaking point as Australia’s housing crisis deepens, with new findings showing demand for help has surged and staff burnout is rising.

If you want to understand Australia’s housing crisis, look at what the government funds
We are living through the worst housing crisis in living memory. Rents are surging, home ownership is slipping further out of reach, and homelessness is rising and more persistent.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...
Gladys Mae West obituary: mathematician who pioneered GPS technology
She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

This is overt racism. Full stop. There’s no ‘misinterpretation’ and no excuse. This is who he is, who he’s always been, and why he should never be anywhere near power again. And there’s a reason the tapes from The Apprentice have never been released.

I think you know the answer. The “negotiations” have been an excuse to hold back necessary equipment and aid.

I am a Ukrainian Nobel Peace Prize Laureate. I have a question.

Why has Trump's year of negotiations been the deadliest for civilians in Ukraine since the full-scale invasion? The number of deaths and injuries has increased by 31 percent compared to the previous year.

One of the most underrated plotting functions in #rstats is coplot(), which produces something similar to #ggplot2 's facet_grid, except that when conditioning on a numeric variable, it cuts it into *overlapping* ranges.

TIL more than just gdal_translate can use all the CPU cores for decompression. So, pass `--config GDAL_NUM_THREADS=ALL_CPUS` to gdalinfo for massive compressed files! 🚀

github.com/OSGeo/gdal/i...
crschmidt: When running gdalinfo -stats on a large GeoTIFF, it uses only one core to compute stats. It would be nice if (for thread-safe datasets) it could run with more than one core. (Seems like this might be more practical now that https://gdal.org/en/stable/development/rfc/rfc101_raster_dataset_threadsafety.html is in place?) In particular, running gdalinfo -stats on CAFA_2020 from https://drive.google.com/corp/drive/folders/1exF1KpGr0EJqZ10yqPIkzqLfh6gGj3Sa took 8 minutes on my Macbook with an M3 chip, which seems like it could have gone faster with multi-threading. <snip> rouault @crschmidt Wouldn't https://gdal.org/en/latest/programs/gdal_dataset_check.html added in master a couple days ago do the job as far as your goal is concerned? (i.e. it reads all blocks ensuring they don't result in errrors). It is not multi-threaded per se. That said if your GeoTIFF is compressed and you specify "--config GDAL_NUM_THREADS=ALL_CPUS" then you'll get multi-threaded decompression, which should reach close to optimal performance.
