Do I understand correctly that in order to pay someone through your service I need to first create an account and then link it to a conventional card? If so, it's ultimately a PayPal remake?

Customers do create an account and provide a payment method, but they don't pre-fund or hold a balance, and they don't initiate a payment. Small Transfers is an API that allows merchants to charge very small amounts programmatically. At the end of each month (or earlier, if a threshold is reached), we charge the customer what they owe. This makes the tiny charges viable and avoids death-by-$0.30. It's not a PayPal re…

if the customer owes $0.001, how are you charging that?

I 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…

Your docs are great! How did you create them? Did you use external tools to generate them?

Thank you! For the components, I use the Custom Elements Manifest Analyzer to get data from JSDoc comments and TypeScript. This populates properties, events, methods, slots, etc. All the examples and other pages are hand-made. Docs are generated with 11ty.

I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet). It uses 4k stereoscopic capture and bunch of ML models to match bone positi…

Curious if you’ve heard of OssoVR and what your honest assessment of VR training in your field is?

VR training hasn't really stuck in ortho training. It's legit and people do it, but it's a distant second to doing it live. I haven't seen that much of it, but from what I have seen, the fidelity is quite low. It would be cool to see what a good game studio could produce.

Doctors, like most people, don't like stuff on their head. Plus in ortho there is a lot of feel to it. It's often referred to as "carpentry". The docs I know, especially those with experience, would prefer a video and a cadaver lab. Even that's a lot to ask because they are so swamped. In every surgery there is a rep from the implant company, and those reps are really the ones doing the training.

So there is certainly potential but it's just not to the point where people are excited about it.

I’ve been suffering from migraines for the past year and the health system hasn’t been too helpful in diagnosing why. I’ve got some meds, but they’re expensive and not without side effects. So I’m building an app to try and figure out how to avoid the triggers in the first place.

https://dotsjournal.app

Sort of like a digital bullet journal. You setup some rows of events you want to track, then just tap for when/if that events happens. It’s already helped me spot certain triggers for my migraines, which I can now minimize. My wife has been finding it helpful to diagnose sleep problems. I think it might be super helpful to others with trying to understand lifestyle choices and how it impacts their wellbeing.

About to roll out the beta. Hoping to have a full release by the end of the year.

It’s my first iOS app in 8 years! Learning SwiftUI after UIKit has been quite the shift.

A research project on converting a python application from loops to numpy vectorization to jax and pytorch compilation (the latter is fast!). I'm exploring the performance portability of such frameworks across different devices and backends (also gpu). I have also C++ hand optimized implementations that so far are unbeaten

A Kotlin Multiplatform implementation of OpenTelemetry: https://github.com/embrace-io/opentelemetry-kotlin

It's been really fun writing this from scratch and trying to design a mobile-friendly API that fits the OTel spec. There's still work to do on OTLP export and various other features - if this project interests you, please do get in touch!

Cool idea. One suggestion is to allow a selection box to be dragged around a block of letters. Once selected, all of the tiles in the area could be dragged at once. That would reduce the frustration of having to move a large chunk of words around piece by piece. It would be better than the existing affordance, which moves the whole grid.

Thanks! I experimented with this but struggled making it feel natural on mobile. I ended up implementing an alternate solution that I’m hoping solves for the same paint point. My current dev build “merges” tiles when you connect them to complete a word. This allows you to move them as I’m going to release a demo with that feature soon. My core playtesters seem to like it but I want to get more feedback on it from a l…

Merging is exactly what I expected when I put chunks together, with tap to separate them again.
