iiinova — where your digital self keeps evolving

it feels primitive, especially in era of "with ai you can code up anything duh", but i still find it handy to use google sheets as data input + database for various life data tracking projects.

hey, it’s been a while! just dropped by to share that on the mission to look for good domain problems for my visualization projects, i’ve accidentally gone too deep (still not enough though!), and started as a senior researcher at @ceitec.eu bioinformatics core facility last month.

work in progress: made uchimata (github.com/hms-dbmi/uch...) into a Mosaic client, so that I can hook it up with quak (github.com/manzt/quak) for some nice brushing action

my wife **really** wants one of these trader joe’s tote bags. that’s what vibe coding is for.

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.

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.

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."

we’ve got some selections going!

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.

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.

Made a little visualization of my workouts from last year.

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

I have been playing with filtering of 3D structures (represented as Arrow tables) via duckdb-wasm… It’s been going pretty well!

not completely done reading it yet, but this is definitely one of my favorite survey papers: onlinelibrary.wiley.com/doi/10.1111/... interactive browser: uclab.fh-potsdam.de/unfoldables/ @uclab.bsky.social

i’ve been working on rendering many (16+) scenes with threejs in a single page. the performance is…suboptimal.

just got back from the 4D Nucleome annual meeting. always fun to be the one poster with fancy images but zero biological novelty (compared to the rest). folks couldn’t have been nicer and more welcoming though!
