This is from The Last Waltz concert on T’giving Day 1976. No editing & no dubbing, just the raw sound as the concert goers heard it that night. So sublime how they played with, not over, each other. The Band 11/25/1976 - Winterland youtube.com/Ymgvs0KU1L0 via @YouTube

Pretty stunning to see the geographic uniformity of Issue 1's defeat, even compared to challenger GOP candidates. #OhioIssue1

Excited about @CZIscience news for #CZCellxGene Discover Census data into Seurat via @TileDB and the `tiledb`, `tiledbsoma` #rstats packages? How about doing it within seconds in the browser thanks to #r2u, r-universe, and #Rocker devcontainers. Teaser below. More to follow.

If you like that then you will really like r-ci (using all .deb binaries first from c2d4u, now from r2u) and/or the direct r2u setup from my blogpost below. #r2u covers all #rstats (and system !!) dependencies fast, reliably, easily, and automatically. dirk.eddelbuettel.com/blog/2…
This is a big deal if you’re building on ubuntu-latest in GitHub actions, can really speed up your builds.

Another option is r-universe (thanks to @opencpu) which has repositories for source (of course), and binaries (including Ubuntu LTS) # Install quantmod in R: install.packages('quantmod', repos = c('joshuaulrich.r-universe.dev', 'cloud.r-project.org')) joshuaulrich.r-universe.dev/…
There are issues with getQuote() again github.com/joshuaulrich/quan… It's fixed on GitHub, but won't be on CRAN for a couple weeks due to CRAN's summer break. Install the patched version in the meantime: remotes::install_github("joshuaulrich/quantmod") #quantmod #rstats

It's one thing to release a book in the midst of credible allegations about the integrity of one's research. It's another to adorn that book, in an attempt at humor, with made-up endorsements from Anne Frank, Martin Luther King Jr., & Rosa Parks. Distasteful and disrespectful.

This tweet constitutes my bi-annual "Thank You!" 🙏 to @winston_chang for his sumo-style container which once again let me chase and pinpoint an ASAN/clang issue my own ASAN/gcc container did not tickle. Also, CRAN is awesome in its rigour. #rstats github.com/wch/r-debug
