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.

Working with LLMs is a skill that is often based on what you enjoyed about your work. People who love the outcome vs people who love the process.
If you enjoy the process of writing, coding, etc then you’ll hate working with LLMs but if you most enjoyed the finished product then they’re a good tool

I love this expression “malleable software” from www.macstories.net/stories/c… … there is something there and we aren’t even scratching the surface yet. The next 10 years will be exciting!

I was fortunate to have Ami, a great speechwriter, work with me on several White House speeches.

I wrote the speech I *wish* Chuck Schumer would give tonight - as an actual opposition leader. Here it is:
"My fellow Americans: At this hour, an unrestrained force of militarized and violent federal officers is carrying out a project of ethnic cleansing in the streets of American cities."

Senate Democrats will not provide the votes to proceed to the appropriations bill if the DHS funding bill is included.

Anoctamin-2-specific T cells link Epstein-Barr virus to multiple sclerosis
Researchers identified anoctamin-2 (ANO2) as a frequent autoimmune target in multiple
sclerosis, with T cell responses against ANO2 occurring in over half of patients.

I can’t wait to see what software looks like 5-10 years from now. LLMs will change how we do software as there are so many new opportunities. So much of UI design and software is to enable things LLMs can now trivially write. But there are some hard problems we still need to solve regarding access

So much tedium to write good code is just gone with Claude. Still lots for humans to manage though! Our jobs just move to the more interesting parts of development
Most programmers are too lazy and stupid to actually follow known dev practices that result in good code, but Claude will happily spend hours writing tests and iterating to cover every edge case in a way humans just won’t

Callenson had the courage and conviction to stay with the scene and keep filming. Not to run away, but instead to follow the scene. To continue documenting what was unfolding.
I'd like to think I'd have done the same. I'm not sure at all that I would have.

The detailed specs are key. Even before llms… The part of coding I loved the most was setting up abstractions and figuring out state. The implementation was just mechanical exercise I can now outsource with detailed description of what I want.
In essence a language model changes you from a programmer who writes lines of code, to a programmer that manages the context the model has access to, prunes irrelevant things, adds useful material to context, and writes detailed specifications. If that doesn't sound fun to you, you won't enjoy it.
