a fun side project to track Sumo stats.
Every two months there’s a 15-day tournament where 670 rikishi(sumo wrestler) fighting ~160 matches each day. I’m recording all the results and kimarite (winning moves) into a browsable database with charts and videos.
Recently I have been using Gemini to process and edit the daily match videos. It works surprising well. It can detect the start/end of each bout, recognise the wrestlers and assign the correct rikishi id to them.
Still early, but if you want to get into Sumo feel free to join! Its fun to watch and the matches are quick!

#363I launched Quiet UI this week: https://quietui.org/ It prioritizes accessibility, longevity, performance, and simplicity. With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.) Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode. All form controls are form-associ…
Great work!, love the simple aesthetic

#364I’m building a text editor inspired by ed, but instead of editing files on disk, it edits live network flows. In this model, files don’t exist as static objects—they exist in motion.
Creating a file generates a self-sustaining pattern of packets circulating through the network, and editing it changes the flow itself. Multiple users can edit the same file simultaneously, because the file isn’t tied to any machine—it’s in the network.
The interface is familiar if you’ve used ed, with commands like append, delete, and substitute, but behind the scenes it’s all live traffic. You can even discover existing flows and jump into them in real time.
It’s a Linux proof-of-concept using raw sockets, and the goal is to explore what files could be if we thought of them as living, circulating processes rather than static storage.

#365Updating my validation library for python, koda-validate (https://github.com/keithasaurus/koda-validate).
Focusing on ergonomics improvements. Just released an improvement to the __repr__ for Invalid types.
Potentially working on expanding the ability to generate validators from arbitrary typehints, ie `get_typehint_validator(list[str | int])`. It has good coverage, but I suspect I'm blind to some obvious holes. Would love feedback!

I already have a similar project for Typeform, for which someone reached out to me to see if I can help them integrate it into their project.
This project is very similar to that, but it implements Jotform.

#367I’m building an ETL tool that “just works” and gets out of the way. I can write shell scripts and python to do this stuff but honestly I just want to drop my files/API results into a GUI tool and have it combine things for me. Landing page is at https://eetle.com

#368https://pleasetrymyapp.com I've been working on a map that shows which neighborhoods in a city are nice/not nice with a short description. Whenever I visit a new city, just looking at Google Maps is pretty meaningless - it's just a bunch of gray land and streets. I end up looking up Reddit posts for where to go, searching for crime maps, trying to find annotated maps, etc. to get a better idea of where to visit in a…
I have a similar problem where I want map-type data, but it's subjective reviews that couldn't go in OSM directly.
Are you using OSM's nodes and relations and such as foreign keys for your own overlay, or just lat/long?

#369I'm working on Listening Facts[0], a music habits visualization tool based on your top tracks. Inspired by Receiptify and every day nutrition facts labels[1]. It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integratio…
I'm still using last.fm and this is great! Thank you for this.
Thank you for giving it a try!

Just using lat/long points for the polygons.
