Specific details about PLOS Biology's mandatory code-sharing policy

In support of #OpenScience, we routinely ask authors to openly share their #research #code before publication.

We are now formalizing this practice with a mandatory #code-sharing policy and clarifying what we mean by code sharing.

May be nice to cut-out the box for reference

FWIW - I have been regularly using Gemini, ChatGPT and a few others to 'ghost' tasks I'm doing, eg, figuring out emissions intensity of a gas turbine or something myself and then asking the same once I know the real answer

It's remarkable how subtle the errors, false references and mistakes are

(one issue is that we don't have exact dates of de- and re- registration; we have number of days in a calendar year registered, and first and last days of registration in that year. So sometimes we can infer the dates, and sometimes not. We do, however, have exact days of events coded by GPs)

If they de-register from Welsh NHS, they "disappear" for us until they re-register with a Welsh GP (e.g., they move to England for Uni, then come back). We do not have records outside of Wales. Yes, a person an experience A and B multiple times (so for common codes, bias is less).

But we have 15 years of data so I did a simulation adding gaps (modelled on the incomplete data gaps) to complete data to estimate the bias, as a first go

Yeah, that’s the issue; we have Welsh NHS data but they might (say) move temporarily to England for University

Yes, clinical codes (so “GP reports that X talked about Y”)

> but I'm less familiar with this area, so I'm not sure the "best" approaches. Done matching of time periods, restriction to complete data (loses data and for more fatal diseases causes a different kind of bias!), and trying to estimate bias via simulation. If it helps this is population-level data.

To my health researcher colleagues: when you're looking at routinely collected data (over many years) and you're interested in the relationship b/w two kinds of events (say, diagnosis for diseases A and B), how do you best deal with time gaps (eg people moving)? Obviously these introduce time bias >

I'm not linking to yet another White Man On The Internet's blog post, but suffice to say:

No, LLM extruders *can't* do ethnographic research or social semiotic analysis

What they *have done* is flood the zone with slop that makes social science research & analysis infinitely harder than before

She’d Never Changed Her Gender Marker. Kansas Invalidated Her License Anyway. — Assigned A trans Kansas resident recently changed her name but not her gender marker on her license, fearing what Kansas may do if she did. The Kansas DMV still flagged her ID.

This story, from @natezuke.bsky.social, is absolutely wild. A trans woman who never changed her gender marker was issued a letter invalidating her license. At the DMV they cut up her license, which had an "M" marker.

Update: I spent seven tries just to get it to change an uppercase delta to a lowercase one. It kept “fixing” the problem (still uppercase!). After seven tries, it finally just substituted a “hand-crafted” SVG path (!). (I know this is easy to fix myself; wanted to
see if I could do it with prompts)

Yeah, given the extreme cost of the infrastructure just to maybe cut out some boring boilerplate coding? Doesn’t seem worth it.

Yeah, I really can't stress enough that AI code assistants royally fuck up statistical analyses. And they do it with absolute confidence.

I'm specifically testing claims of people I know re: LLMs using a test case that I've already coded myself. I don't think it has streamlined the work, really. It does boilerplate fine, but then I have to check any serious code. Not a net gain (but a change in the nature of the work)

Trying to one-shot this app has been a disaster - there are a bunch of interconnected animations/interface dependencies between parts of the app that it just screws up. Building it one logical step at at time seems to work better. I've tried it three times in various ways.

Also, sometimes a change will completely hose the app. The order in which I ask it to add features is very important (in ways that seem logical given that it doesn't...know...anything, but still - if you thought this was anything like asking a person to complete a task you wouldn't understand why.

> d3.js code with animations, but "vibe coding" scientific apps is likely to be very dangerous. I would need to completely gut this app of the backend stats functions and substitute my own.

And, in fact, in my own code I use this fast *approximation* for animation speed before replacing it with the correct answer after the animation stops. But here it has simply used it has the "correct" answer. Of course, this doesn't mean that using Claude might not have save me time writing >
