playing around with umap-js today.
Instead, I can have Claude figure out stuff like library API changes, or even mock responses from data servers that are no longer up. In the end, I can actually interact with the tool and see what's realistically possible.
For example, this is a research software that hasn’t been touched in 7 years (according to Github). Making it run manually would probably take way too much time and effort so I’d default to making assumptions based on the paper. link.springer.com/article/10.1...
A screenshot of a paper figure with caption. Highlighted text in the caption reads "Pink arrowheads indicate the 2D to 3D mapping of the highlighted region in Hi-C heat map on the 3D model. The green arrowhead indicats the 2D to 1D mapping of the selected region in 1D yeast genome (shown in orange for the recently selected region). Each selected region will be mapped to an individual 1D genome."
A nice use case for Claude Code in my work: reviving old research prototypes. When it comes to surveying interactive features of past tools, we often have to rely on static figures and descriptions in text. Sometimes there’s a video. That can be pretty limiting.
we’ve got some selections going!
revisiting my webgpu-based 3D scatterplot library after a year.
I closed that account on August 14, 2024. The bio on the fake profile is taken verbatim from my Github, same as the cover photo.
A screenshot of my previous twitter profile (@dvdkouril). Highlighted are two dates: one showing 'Joined January 2015' and the most recent repost of a post dated October 13, 2023.
A screenshot of a fake profile using the same handle (@dvdkouril). Highlighted is: 'Joined April 2020'
A screenshot of email conversation with X Support, showing that I reported Impersonation on this account. All the options are irrelevant as they are concerned with restoring my account.
Just so you know: if you delete your twitter/x account, it will come back up at some point, and show that it’s been active from an arbitrary, impossible date. Reporting impersonation is also useless.
I also really like the part around 27min mark, where he talks about the visualizations that people make of the problems. That's what I would often default to...naturally...
TIL that Advent of Code was invented in Salem, Massachusetts www.youtube.com/watch?v=uZ8D...
i can’t be the only one who procrastinates on work by making tools for tracking and visualizing work

haven’t seen that much snow in a while!
a calendar view of 2025, divided by months. each day is color coded based on exercise type or gray which means no exercising that day
Made a little visualization of my workouts from last year.
hello, marimo
screenshot of very many colorful circles
even more colorful balls
instead of advent of code, i’m spending my december on this #webgpu
So there won’t be any streaming for the whole conference, huh? That’s a huge bummer.

I have been playing with filtering of 3D structures (represented as Arrow tables) via duckdb-wasm… It’s been going pretty well!
Maybe juv can be useful for cases like this, has been for me! github.com/manzt/juv @manzt.sh
not completely done reading it yet, but this is definitely one of my favorite survey papers: onlinelibrary.wiley.com/doi/10.1111/...

totally unrelated to anything happening these days, but I now have a CV on my webpage: davidkouril.com/cv

IMHO, make this the default, github: github.com/ghostty-org/...
