Some times when I read code for papers I find it hard to believe that people care so little for the craft of their work. I have to constantly remind myself that its lack of aesthetic sense doesn't always mean it is bad.

With various things in the news and maybe time passing, COVID discourse seems to be coming around again and the main thing I can share as a specialist is how different pandemic preparedness is from standard politics or almost all the other things in the Opinion columns. Primarily, a lot of >

I really think the solution has to be open source but not open contributor projects. A small barrier to being allowed to open a PR goes a long way.
So there's a thing happening on open-source repos: people who are otherwise uninterested in your project but want to obtain clout will file mediocre PRs against your repo anyway. So: community tarpits? Create a legit-looking repo with a bunch of open issues, wait for PRs, blacklist those accounts

In 2017, while working at Epicentre/Medecins Sans Frontieres I helped to develop the Urgepi program in southeast DRC. What started as measles surveillance program has matured into a prioritization scheme for outbreak prevention and response that serves 15m people (land area ~Spain).

What is an 'everyday task' and what is a 'complex problem' in bioinformatics software engineering? Feels more important use the right model now they're not so heavily subsidised! I did a small comparison on an optimisation task: johnlees.me/posts/ska2-c... Small/cheap model wasn't good enough

Agentic coding models such as codex and claude code are really useful for software engineering tasks. We sadly (and unsurprisingly) seem to be exiting the era of highly subsidised costs to get us hook...

Yesterday marked two months since the DRC declared the ongoing Ebola outbreak, @drtedros.who.int says in presser. "It's now the third largest Ebola outbreak on record, and in the past months, it has expanded faster than any previous outbreak."
Looking forward to teaching the nowcasting half of our nowcasting and forecast course at SISMID starting today! Some nice (I hope) new content on modelling workflows vibing on the Bayesian workflow book from @avehtari.bsky.social et al. and new session on complex reporting processes.

Really enjoyed giving a short workshop on what is a forecast and is it any good at #iddconf. I lasted attended (I think) 8 years ago as Phd student and loved it so looking forward to the talks and community. Our workshop material is here: nfidd.github.io/iddconf2026/
What is a forecast, and is it any good?

Looking forward to this tomorrow at 3pm uk time. The workshop was great.
Are you interested in survival analysis or infectious disease modelling? Ever wondered how the two could contribute to one another? 🤔 Well come along to the next Epinowcast seminar tomorrow!
Great to see {epidist} and so @paulbuerkner.com {brms} and @mc-stan.org getting used as part of the reporting of the clinical characteristics of the Bundibugyo Virus outbreak in the DRC.
New paper: We recast automated scientific model discovery with LLMs as Bayesian inference! LLMs write code and carry domain knowledge, great for proposing models. The key idea: discovery is inference, not just generation. What distribution of models explains the data? 🧵 arxiv.org/abs/2602.18266
A new paper by @dominiquemakowski.bsky.social, @mattansb.msbstats.info, me and colleagues just out! We show how to choose informative priors in Bayesian regression models using a systematic simulation study and a practical step-by-step tutorial in #Rstats and #Stan! doi.org/10.3389/fpsy... >

A few weeks ago @sbfnk.bsky.social was doing some re-estimation work for www.nejm.org/doi/10.1056/... (lovely dataset and paper) We just landed a real-time version of the model (i.e. that you could use in real-time and not (ideally) get biased estimates.

Found my first vibed up port of some of my work today into another language stack (without the statement that is what it is of course but looks fairly clear). Very interesting to think about what this means for the future.
This is happening now
Happening today! 3pm BST / 4pm CEST Come hear some lightning talks on modelling/modelling-adjacent work relevant to the current Ebola outbreak, and stay for the discussion! We'll leave plenty of time for it 🌟 community.epinowcast.org/t/community-... #Ebola #BVD #PublicHealth #InfectiousDiseases
