“‘Out of curiosity,’ says the patient, hoping to delay the injection, ‘what was the odds ratio for those without the genetic variant?’ The doctor pauses, puts down the needle, and turns back to the study. ‘The odds ratio for those without the genetic variant was also 4.’”

Knowing that I said something profound enough to be in your blog post is an honor :) My own irreverent take on odds ratios: ngreifer.github.io/blog/an-odds...

On Thursday, I'm giving the last of the 2026 Ihaka lectures on "Spotting the weird ones" (about anomaly detection using #rstats). It's an honour to speak at something named after Ross Ihaka. It will be live-streamed for those who can't be there. www.auckland.ac.nz/en/science/a...

Heads up ruff users - with the release of 0.16.0 this week the number of default rules went up from 59 to to 413. This means that if you're ruff version auto updates, your CI pipelines might start failing on you all of a sudden.

Ruff 0.16.0 - Astral's fast Python linter - came out a few days ago and increased the number of default-enabled rules from 59 to 413, which highlighted all sorts of problems across my projects (1618 in sqlite-utils alone) simonwillison.net/2026/Jul/25/...

Many people talk about the "Golden Age of Antibiotics", but I hadn't seen it visualized properly. Just how many types of antibiotics were discovered during that time? So, I visualized it myself!

A timeline titled "The Golden Age of Antibiotics" shows when each antibiotic drug class was first available for medical use, with example antibiotics labeled. Classes are color-coded by their source: actinomycetes, other bacteria, fungi, or synthetic. Milestones include the first antibiotics (arsphenamines in 1910), as well as the discovery of many actinomycetes-derived antibiotics, such as streptomycin, and sulfonamides, penicillins, and tetracyclines. Data: Hutchings, Truman, Wilkinson (2019). Created by Saloni Dattani for Our World in Data.

One week from today is the first of the 2026 Ihaka Lectures. Kieran Healy will speak about "Trustworthy Data Visualisation" It's in Science bldg 303, opposite Albert Park. Refreshments 6pm for 6:30pm start (NZST, UTC+12). There's live streaming and a recording later.

the food safety stuff is another reminder that a large, huge, gigantic part of being a republican is going “lmao why are we spending money to prevent horrifying disasters from happening if they never happen 🤪”

Latest version of Positron can open xlsx files in the data viewer(!) and it has a dropdown menu now for previewing different formats of #QuartoPub documents And—most importantly, but also from a few weeks ago, so less new—the plots panel can pick up dimensions from chunk options!!!! #rstats
