What an astonishingly dishonest piece of propaganda for the fossil fuel industry, including its citing of Obama's extremely outdated energy policies and its misrepresentation of Norwegian public opinion.

New York Times Opinion @nytopinion.nytimes.com · 8d

“The mind-set shift needed here is to acknowledge that while climate change is real and harmful, the utility of fossil fuels is not something the oil and gas industry tricked the public into,” Matthew Yglesias writes.

Opinion | Obama Supported It. The Left in Canada and Norway Do. Why Don’t Democrats?

I am just learning of this 2015 retraction, adding to my "science as amateur software engineering" files. Seems they classified missing values as obs outcome of interest (divorce). Classified 32% of sample divorced, rather than true 5%. retractionwatch.com/2015/07/21/t...

Here’s the original coding line:

replace event`i’ = 1 if delta_mct`i’ != 0 | spouse_delta_mct`i’ != 0

And here’s the corrected coding:

replace event`i’ = 1 if (delta_mct`i’ != 0 | spouse_delta_mct`i’ != 0) & delta_mct`i’ != . & spouse_delta_mct`i’ != .

My in-law family has told me about the tiny, intense pink shrimp that were harvested in stormy seas in Maine winters.

Now warming oceans have reduced the shrimp population to almost nothing, and the fishery has been officially closed.

Fishing regulators are extending a shutdown for New England’s historic shrimp fishing business, effectively shuttering an industry that fell victim to warming oceans.

In this article, just out, I argue that scientists have a crucial role in the science-policy interface: keep making questions, especially those whose answers decision-makers don't know they want to know, or know they do not want to know.

Andrew Heiss @andrew.heiss.phd · 17d

Some closing thoughts for my students this semester on LLMs and learning #rstats datavizf25.classes.andrewheiss.com/news/2025-12...

Will you incorporate LLMs and AI prompting into the course in the future?
No.

Why won’t you incorporate LLMs and AI prompting into the course?
These tools are useful for coding (see this for my personal take on this).

However, they’re only useful if you know what you’re doing first. If you skip the learning-the-process-of-writing-code step and just copy/paste output from ChatGPT, you will not learn. You cannot learn. You cannot improve. You will not understand the code.

In that post, it warns that you cannot use it as a beginner:

…to use Databot effectively and safely, you still need the skills of a data scientist: background and domain knowledge, data analysis expertise, and coding ability.

There is no LLM-based shortcut to those skills. You cannot LLM your way into domain knowledge, data analysis expertise, or coding ability.

The only way to gain domain knowledge, data analysis expertise, and coding ability is to struggle. To get errors. To google those errors. To look over the documentation. To copy/paste your own code and adapt it for different purposes. To explore messy datasets. To struggle to clean those datasets. To spend an hour looking for a missing comma.

This isn’t a form of programming hazing, like “I had to walk to school uphill both ways in the snow and now you must too.” It’s the actual process of learning and growing and developing and improving. You’ve gotta struggle.

This Tumblr post puts it well (it’s about art specifically, but it applies to coding and data analysis too):

Contrary to popular belief the biggest beginner’s roadblock to art isn’t even technical skill it’s frustration tolerance, especially in the age of social media. It hurts and the frustration is endless but you must build the frustration tolerance equivalent to a roach’s capacity to survive a nuclear explosion. That’s how you build on the technical skill. Throw that “won’t even start because I’m afraid it won’t be perfect” shit out the window. Just do it. Just start. Good luck. (The original post has disappeared, but here’s a reblog.)

It’s hard, but struggling is the only way to learn anything.

You might not enjoy code as much as Williams does (or I do), but there’s still value in maintaining codings skills as you improve and learn more. You don’t want your skills to atrophy.

As I discuss here, when I do use LLMs for coding-related tasks, I purposely throw as much friction into the process as possible:

To avoid falling into over-reliance on LLM-assisted code help, I add as much friction into my workflow as possible. I only use GitHub Copilot and Claude in the browser, not through the chat sidebar in Positron or Visual Studio Code. I treat the code it generates like random answers from StackOverflow or blog posts and generally rewrite it completely. I disable the inline LLM-based auto complete in text editors. For routine tasks like generating {roxygen2} documentation scaffolding for functions, I use the {chores} package, which requires a bunch of pointing and clicking to use.

Even though I use Positron, I purposely do not use either Positron Assistant or Databot. I have them disabled.

So in the end, for pedagogical reasons, I don’t foresee me incorporating LLMs into this class. I’m pedagogically opposed to it. I’m facing all sorts of external pressure to do it, but I’m resisting.

You’ve got to learn first.
