Nick Karpowicz @nickkarpowicz.bsky.social · 04/09/2025nickkarpowicz.github.io/widgets/frog/ Hi ultrafast people! I wrote a FROG reconstruction that will run entirely in your web browser. This I why I like #marimo so much :) The python/rust code for it is all in our attoworld github repository.nickkarpowicz.github.iofroga marimo app 110
Nick Karpowicz @nickkarpowicz.bsky.social · 15/06/2025Thanks, John! It was your amazing foundational work which got me interested in trying this in the first place, and I really appreciate your openness about everything! I think solitons in hollow-core fibers are going to do a lot of work in attosecond and ultrafast optics in the coming years :) 020

Nick Karpowicz @nickkarpowicz.bsky.social · 21/03/2025I'm really enjoying marimo as a replacement for Jupyter notebooks! The fact that I can make little interactive widgets accessible by the web will be great for next semester's photonics course.

Nick Karpowicz @nickkarpowicz.bsky.social · 19/12/2024AI people argue that it's not plagiarism, that it's like learning and then making something new. But all of the artwork that goes in defines the space where the model operates, and it will never redefine that space.
