https://sumostats.com 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…

Given that people bet on sumo, wouldn't people pay a lot of money for your stats?

Haven't met anyone who bets on sumo so I don't know. The stats are out there, so I don't think its worth anything more than a bit of ui convenience

I've been building https://resolver.one - a DNS server that returns GeoIP data as TXT records. Query an IP directly as the hostname (e.g. dig TXT 8.8.8.8.rslvr.one) and get back country, ASN, etc.

Always been fascinated by repurposing established protocols for unintended uses - DNS is everywhere, passes through firewalls, and has built-in caching. Seemed like a fun way to deliver location data without HTTP APIs.

Super niche, definitely a bit odd, but that's the appeal.

Earlier quoted context omitted.

I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.

Consumer Lab does this testing. It's great, you just have to pay for a membership.

Thank you - had no idea.

Neat idea, even if it doesn't end up going anywhere.

Out of curiosity, are you able to share what your source of data is? Isn't GeoIP data typically licensed?

Https://KushtyBuckRecords.com Been thinking a lot about tools for modern musicians/artists/producers. Not tools for creating the music but tools for communication. Email subscriber lists, event creation (image and text) combined with ability to generate QR codes and send them with easy to use dashboard, some kind of insights into the QR scans, merchandise (integrations with Shopify), hn style link aggregation around music.. been building it with my son who also becomes my product manager since he the one using the tools. For now a private repo consisting of a rails API and a react TS frontend app. Everyday I come up with some small improvements in my head but alas not enough time in the world. With the day job an all, this is purely a passion project and a way to help my son follow his passion, putting on house music events and DJ/producing. If anyone interested, plz reach out contact@kushtybuckrecords.com

Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics. I've been playing guitar for a little under 6 years and ran into the common problem amo…

Reminds me of John Petrucci's Rock Discipline instructional video where he outlines exactly this technique on how to build up speed.

Great instructional video. First place I learned E natural minor with his scale fragments section.

Yes, not a new technique by any stretch of the means. AFAIK John Petrucci takes a less aggressive approach with raising BPM. Funnily, Shawn Lane goes into a very similar methodology >30 years ago[1].

Kanji Palace - https://kanjipalace.com

I'm building an app to help people memorize Kanji by turning the characters into vivid, memorable images with accompanying mnemonic stories.

I think AI image and video models have reached a point where they can offer a completely new approach to language learning.

Next, I'm planning to add features that use AI to generate comic strips (using Seedream or Nano Banana), songs (using Suno) and videos (using Veo 3 or Seedance) to make learning Kanji even more engaging.

https://finbodhi.com — It helps you track, understand, and plan your personal finances — with a proper accounting foundation.

It's a double-entry personal finance tool where you own your data. It’s local-first, syncs across devices, and everything’s encrypted in transit. Soon with multi-currency support. Currently targeted for desktops.

It's interesting in many way. Using double-entry (it's a perspective shift and a power tool), the challenges and advantages of building local-first app, UI/UX & visualizations, privacy and more. For personal apps, local-first is a good fit.
