NSF’s flagship fellowship program is rejecting applicants without peer review Students seeking graduate research scholarships speculate that biology is being disfavored

NSF's graduate research fellowship (GRF) program is designed to teach aspiring scientists how to write a winning grant proposal. So why are so many applicants being denied that learning experience? www.science.org/content/arti...

Helpful trick for academic writing with #QuartoPub: sometimes when trimming down papers, you've got to remove references (ughβ€”bibliographies shouldn't count in word counts!) so I use this #rstats snippet to extract all citations & and find things that I've only used once to see if they're droppable

A hex logo with 'lintr' written in light blue stitch. The angled white band behind this lettering appears to be "wiped on" by a lint roller at the right end of the hex. The rest of the hex is a Nordic knit sweater pattern in various shades of blue.

i wrote about the meme that academic code is bad, what i think is achievable, and why i don't think we should be trying to get academics to write software for production

would love to hear what folks think!
