I had to install #Stata today to run someone else's code. Considering how quickly #software adoption changes in other fields, it is astonishing how something as outdated as Stata has managed to survive until 2026.

Since publishing the Monash SoDa Replicator, users have told me about Windows laptops provided by their university not allowing for local TeX Live installation. Hence, I have created a dev container that circumvents this problem: github.com/cdueben/tex_.... #tex #texlive #devcontainer #vscode 1/2

David Kreitmeir and I published the synthetic matching method from Kreitmeir et al. (2025) as an #rstats package on CRAN (cran.r-project.org/package=synt...). Whereas my other recent R packages are primarily wrappers of my C++ code, synthReturn is a full R package (Fortran only in dependencies).

My cppcontainers #rstats package (cran.r-project.org/package=cppc...) is back on CRAN. The functionality remains unchanged. It had just been archived on CRAN a few months ago because of NA placeholder values that threw compiler warnings in exotic builds on macOS. #cpp #datascience

Enjoying my first time at @defcon.bsky.social. Amazing talks, demos, etc. so far. And I met famous journalist @jackrhysider.bsky.social whose inspiring work got me interested in #infosec in the first place. I am gathering a lot of insights for my own research.

#AI is even better than I am in adding seg faults to my code 😅. Maybe vibe coding a Fibonacci heap into my spatial analysis was not the best idea. #cpp

I tried #Positron today. Forking and customizing VS Code instead of further pushing RStudio was a good choice. RStudio is not bad, but Positron seems nicer (and better for #rstats development than VS Code itself). Good job @posit.co👍.

There is a lot of childish discussion on the future of #rstats recently on this platform. #rstats is my main language and I will stick to it for a while. However, posts calling it perfect and denouncing any critique as invalid are ridiculous. #rstats has flaws that can threaten its future. 1/n

I need to put together a deep learning model and I do not know whether I should go with #pytorch or #tensorflow + #keras. I have a little experience in the latter and none in the former. What would you recommend for someone who does not care about how pythonic a tool is?

I just had to install the most intrusive #software of my life. It automatically starts at boot, but does not show up in the OS's auto startup list. It does not have an exit button or settings. I have to shut down the background process in the process viewer/ task manager each time. 🫣

The new version of my spaths #rstats package (cran.r-project.org/package=spaths) removes the edge limit (previously 2^31 - 1). Do you need to handle 10 billion edges with custom transition functions? No problem, spaths can do that. #graph #theory

Over the course of the past years, I have received a number of emails asking why conleyreg (my first #rstats package) and fixest produce different results. Contributors to an issue in fixest's GitHub repo have now shown that both are economically correct. The assumptions just differ.

My new way of managing my #research projects' to-do lists: #GitHub issues (with authors assigned to them). (i) More persistent than scribbled down notes from meetings and conferences. (ii) Easy to reference in code commits. (iii) Separate topic-specific written discussion with coauthors. 1/2

Does anyone have advice on how to reduce #political #propaganda in the feed? I welcome political news, but most of my feed is more manipulation attempt than news. Here on #Bluesky it is primarily left wing ideology, while X has also lots of right wing propaganda. How do I get a more neutral focus?

Most #economists do not have formal training in #programming and usually stick to whatever language they learned as undergraduate students. In my experience, broadening the coding horizon can enhance empirical #research producitivity. A thread 🧵.
