Here I tend to read a lot of negative comments about #LLMs, but does anyone share my experience? I use them as an aid to mostly write #rstats and #LaTeX #tikz code faster or recently to clean up a very messy #emacs configuration file. They may hallucinate and I always need to double check the output, but I find #LLMs extremely useful. The ecological footprint is a discussion for another day.

Dear #RStats experts, which tools and models do you recommend for #nowcasting univariate time series? In the past I used glmnet and lagged auxiliary time series, but there must be something less "artisanal". Thanks!

Dear #RStats and #Python users, I am struggling to rectangle, i.e. put in a tabular form, a #Marc21 #xml file. What do you suggest for handling #BibliographicData in this format? I tend to end up with tables where several entries are a list of subfields. Thanks!

Dear #Rstats experts, I read the #duckplyr docs at https://github.com/tidyverse/duckplyr?tab=readme-ov-file#analyzing-larger-than-memory-data (and waiting for my slow machine to instal duckplyr). I wonder if anyone can point me to a tutorial like https://francoismichonneau.net/2022/10/import-big-csv/#the-dataset-api-in-r which converted me to arrow. My starting point at work can often be a large flat csv file which needs to 1) be converted into a parquet file without being read into RAM and 2) be analyzed later on. 2) is addressed by duckplyr as well, but 1) is not clear to me. Thanks and a wonderful 2025!

Really something apart from #RStats : https://inv.nadeko.net/watch?v=Vitf8YaVXhc&listen=false or https://www.youtube.com/watch?v=Vitf8YaVXhc . The first example of a bouncing photon as clock, plus the velocity of light which is constant in any reference frame and Pythagoras theorem make for a compelling example of time dilation in special relativity. #RelativityTheory . Another example of seeing far because we are on the shoulders of a giant.
