There is a finite but reasonably generous free layer of several hours per month at GitHub. At least for -- long-term fear with *all* cloud services is of course that they rope us in and squeeze us later. We shall see.
For now it is not bad and there edu discounts too.

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.

You can have your cake ("newer package") and eat it to ("bird logo") See eg lifehacker.com/you-can-chang…

Again from "team devil's advocate": you are basically arguing that domain expertise does not hurt. 😜
Playing devil's advocate here: Hasn't that been the case since time immortal? Methinks you always need to balance attention to detail and the bigger picture.

I use this at the end of my ~/.Rprofile:
if (interactive()) {
utils::assignInNamespace("q",
function(save = "no", status = 0, runLast = TRUE) {
.Internal(quit(save, status, runLast))
}, "base" )
}
Then q() does what you want without dialog.

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.

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

One more vote for blsky which is coming together well as a alternate.
I have a spare invite if you need one, email me if you do and want it.
That's pretty.
I am somewhat sad though that your epic train ride didn't get you into upstate NY. Kiddo #2 was there for college for a few years and I (as an expat European) considered going by train from Chicago as a nice "hypothetical". This being the US it never happened.

Yep. Currently reading "The Idea Factory" by Gertner about Bell Labs and US Innovation. Bardeen, Shockley, Brattian, Shannon, ... but (odd to both you and me) no mention of later years and Kernighan, Ritchie, Stroustrup, Chambers, ...

Yes, I have examples in slides from intro HPC tutorials. The basics are the same: the jobs need to be slurm-aware. Slides 80+ cover slurm examples

r-base 4.3.1-3 adds a Debian-specific 'Breaks:' creating trouble for the Ubuntu repos, see issue below. I have addressed it in #r2u which is ok now, and contacted @marutterstat for a possible Ubuntu build fix. Sorry for the trouble this caused. #rstats github.com/eddelbuettel/r2u/…
