**V. loosely scoped question** talked to a student about connections between Bayes & freq, e.g.: empirical Bayes [state-space, mixed models, penalized splines]; regularization/regularizing priors; sampling vs optimization (Monte Carlo EM/MCMC vs MLE/MAP). Suggest books/blog posts/papers on this ...?

(1/?) As happens periodically, someone has popped up on the R help list asking for someone to fill out their 'vendor security' form (does you product do security audits, who can we sue if something goes wrong, etc.) Feels like there must be a market for someone to provide such security guarantees.

Hmm, Kobo daily deals is offering _Brave New World_ and _The Stranger_ as YA books ... ? I know these are often on high school reading lists, but seems weird. (Not sure CS Lewis would be happy being listed adjacent to Huxley and Camus ...??)

(1/?) Thinking ahead to fall semester (??!?) and wondering about quarto frameworks that would work well for class, including (1) creating multiple versions (skeleton for handouts, complete for presentation) and formats (revealjs, docx, pdf); (2) macros for highlighting glossary words etc;

🚨 @rmcelreath.bsky.social @statmodeling.bsky.social & @avehtari.bsky.social are coming on the show mid-June to discuss their new book, Bayesian Workflow! ONE listener gets to bring a real Bayesian problem onto the recording and have the three of them work through it live. Here's how to enter 🧵

If you've submitted to Journal of Statistical Software in the last few years and have comments (good or bad) about the review process (time lag etc.) could you please DM me ... ?

The International Statistical Ecology Conference is extending abstract submissions to May 29, 2026 (AoE). Want to encourage more folks in 🇲🇽 & LATAM to participate. Spread the word to your colleagues in Latin America. Happy to answer any questions about the conference! statisticalecology.org

Do you know a good framework to document data analysis choices? Ex: dropping obs, recoding a var, tuning pars, model + test statistics, etc. Ideally human-readable so people don't have to read my entire codebase. Low-maintenance+ machine-readable for bonus points! #RStats #PyData

Ok Bluesky hive mind - please tell me what this figure represents. On the ceiling of one of the galleries in the Doria Pamphilij in Rome c C18th. At first glance I thought it was a musical instrument. Maybe architecture?

That fireside chat with Jay Bhattacharya: a view from across the pond - “In his answers to difficult questions, Bhattacharya revealed himself as someone who gets very uncomfortable when confronted with inconsistencies in his behaviour or views.”

transcribe AMR (sound recorder) file to ABC automatically they said ... it'll be easy, they said ... (AMR →WAV [ffmpeg] → midi [ waon kichiki.github.io/waon/ ] → abc [abc2midi] → PostScript [abcm2ps] → PDF [ps2pdf]. Unsurprisingly, WAV → midi is the weak link. (Should try a simpler round trip next)

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.
