Watch this. Then remember that the president doesn’t care. He cares that his old ass gets richer in the hand full of years he may have left.

And his sick rich friends. The most corrupt evil man to ever serve as president is ignoring real evil

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

NSF

- Forced reorg

- POs down ~ 40% (DRP, most rotators not renewed, retirements)

- Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …)

I personally love the boxes they gave us for packing.
“Details matter” 🙃

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.

One of the open positions at NIH is the Deputy Director for Intramural Research. This is an important position (sort of like a dean who coordinates the intramural programs in the various institutes).

This position is advertised on Facebook. Here is a winning comment.

YouTube video by euronews All aboard except the driver? A fully autonomous train takes to the tracks in Germany

1. In Hamburg there is a "fully autonomous train" that for some reason has a human operator to press the ON switch first thing in the morning and the OFF switch at the end of the night. In a recent talk about AI in science, I asked the audience to consider whether they want to be like that operator.

Universities will keep sexual predators on the faculty because their "hands are tied by tenure." Turns out protesting genocide is all it takes to loosen those unshakable chains.
