Attending a Python HPC workshop organized by Uni. Luxembourg. Fun.

Used a ChatGPT to write an R script to (1) generate a synthetic (random walk based) GPS dataset in Zurich, Switzerland, (2) apply a moving average smoothing for geographic coordinates, and (3) visualize them. #gischat

Enjoyed reading a paper on "spatial causality" by Kamal Akbari et al. (co-authored by @dinomirmt.bsky.social). This article provided me a nice guideline and insights. 👏👏 DOI: doi.org/10.1111/gean... #gischat

So excited to announce that our textbook with Xavier, "Difference-in-Differences for Simple and Complex Natural Experiments", is now under contract with Princeton University Press. Check out the "working textbook" version here! Comments welcome! papers.ssrn.com/sol3/papers....

Large language models, embedded within agent-based models, can simulate competitive market dynamics, according to the authors of this interesting new paper: arxiv.org/pdf/2310.175...

Yejun Lee, the research assistant who worked with me this summer at LISER, was selected as a finalist for SIGSPATIAL SRC, out of the "COVID-Contrail" research project & will present work on "Robust Contrail Detection by Mitigating Label Bias via a Probabilistic DL Model" in Hamburg, Germany.

I am thrilled to attend @FOSS4G_Asia2023 held in Seoul, Korea this year. I'll give oral and poster presentations: a talk on mobility analytics in R & a poster on contrail detection project. I appreciate @LISER_UDM supporting this travel. #gischat #foss4g #gissky #opensource

The strain on scientific publishing 📄: We've got issues. Scientists overwhelmed, editors overworked, constant special issue invites, mass article retractions, journal delistings… JUST WHAT IS GOING ON!? See: arxiv.org/abs/2309.15884 A 🧵1/n #AcademicChatter #PublishOrPerish #PhDAdvice #PhDChat

Tried to install GeoNetwork on a remote Ubuntu VM and failed (partly due to the network setting) and will try it again next week. Now trying to install it on my MacBook with Docker. #gischat
