I've decided to do it simply because of my grandmother: she dislikes bracelets and smartwatches because they’re uncomfortable and she often forgets to wear them. A contactless device could be much more practical for her and for many people like her.

#473Solar-powered data center in a desert. Fully off-grid using solar, batteries and Starlink for uplink. Focusing on AI inference at the beginning. Currently building our first prototype and testing cooling solutions. https://solarcube.com

#474I've been on and off attempting to reverse engineer old Sierra games in Godot. I've brought in AI to build tooling to speed up asset extraction from the old game files which has been a huge help. I just got building placement working last night which was a huge win. This is part of a small hobby where I try to recreate aspects of old games myself to see how I would implement them. I eventually hope to have the skills…

#475Can't really share any useful link at the moment, but I’ve been working on a solution based on the C1001 mmWave sensor. It collects telemetry throughout the night, including respiratory rate, heart rate (BPM), number of turnovers, apnea detection, and overall sleep quality - you just need to hang it around the bed. The data is sent to a server, which generates a nightly report and passes it to an LLM for analysis. I'…

#476We made it possible to run the model in webGPU and it is pretty fast even in that environment. You can see the porting process in my last few submissions, because we livestreamed Claude Code porting the base model from the original C++ and Python.
In a separate initiative, we produced a new hash function with AI - however, although it is novel, it might not be novel enough for publication and it's unclear whether we can publish it. It has several innovations compared to other hash formats.
We are running some other developments and experiments, but don't want to promise more than we can deliver in a working state, so for more information you just have to keep checking stateofutopia.com (or stofut.com for short).
Our biggest challenge at the moment is managing Claude's use of context and versions, while working on live production installs.
Everything takes time and attention and Claude Code is far from being fully autonomous building new productive services on a server - it's not even close to being able to do that autonomously. We feel that we have to be in the loop for everything.

#478I've been working on this project, which lets you create interactive Valentine’s Day invitations for your special someone. You can pick from a set of templates, add your own message or photo, and share it easily.
Currently, adding CMS feature so that user can edit their info right in the website and get the link instead of them hosting themself or editing the code.

#480Been bored a bit, so working on a Coop exploration app, already on AppStore - https://apps.apple.com/jp/app/ato-explore-together/id6757285... . Basically tracking where my friends and I have collectively been by dividing the global map into H3 hexagons. The using photo and workout metadata to get the locations, giving points and doing comparisons between everyone. It’s actually quite fun to see random people around t…
