Purdue CS. I like matrices, graphs, networks, tensors if they fit, energy efficient stuff, Julia (I’m ex-Matlab), Laura (my wife), data, clean air, 3D printing, vaccines (especially for kids), cooking, hiking, skiing. I’m quiet so I don’t say too much.

A question I have … what should papers be? If you have a specific question, where the answer is a theorem/theory, then LLMs are really good at answering it. So why write papers about those answers like we used to do? Maybe, we should focus papers on the questions?

On LLMs in research/theory/math. I feel like the difference between how people value this is simple. If you find the value is in the outcome (the theorem), then LLMs are awesome. if you find the value is in the journey (the way to find the proof), then LLMs ruin it.

Crazy. I ran a cost estimate for a solar and battery system. If you use current low end prices it ties our current kWh price from grid (.18 kWh) assuming replacing batteries every 10 years and panels every 25 over 50 years. But needs 30-40 kw of panels. So not feasible to build.

Me: Ahh! new “almost-linear time matching algorithm” … can we implement it? Codex: No. It just uses a normal algorithm for anything with less than ~10^(30000000000000000000000) vertices. Me: Oh, my graphs aren’t that big.

A dialogue with Codex analyzing the new algorithm from OpenAI. It reports it will need graphs with 1 followed by 30 sextillion zeros in order to work.

Modern economic development is about maximizing complexity. To make things more complex, you need abstraction. Abstraction requires organization and communication.

I’m annoyed by all the academics stressing “quality over quantity” as a tonic for the LLM deluge of results / crap. People have been saying this for years. Either setup a compact with some language on putting this in hiring documents/recommendations/etc. or stop saying it.

ChatGPT gave me bad advice on how to fix an overly bitter ipa.it suggested adding salt. I asked about lemon. Did a taste test. Lemon was better. “Super intelligent” but ignorant about human experience.

I always get a lot of grief online when I write that the solution to America's problems cannot be "Democrats win every election forever." That's not democracy. The solution is having at least two parties where the major center-right and center-left parties accept liberal democracy.

Here's a person that thinks posting the deranged cursing at me in a DM from someone is "leaking" a DM. What kind of moron do you need to be to think spewing hatred at someone in DMs is somehow privileged from public view? Very, very stupid people.
