Like many academics, Arthur Charpentier thinks a lot about publishing papers in journals. Specifically, we wondered if there was a way to figure out which journal was the best place to publish his next paper and have it accepted: I was wondering if there were clusters of journals, i.e. journals that publish almost the same kind of articles (so...

Last night, while working on something else that I want to finish, I ended up indulging in a bit of "yak shaving". I wondered how easy it would be to generate graphics in ggplot2 with rounded corners. I don't think that there is any nativ...

Tiobe Software ranks the popularity of programming languages based on references in search engines. While the methodology might be debated in terms of the absolute rankings it produces, it is quite interesting to see how the rankings fluctuate over time: Tiobe has produced a monthly report of rankings based on this methodology since 2001.
