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!

#673Currently bootstrapping a SaaS side project: https://diplomium.com Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation. The bigger picture: Certificates…
Wonderfull nice looking and clear landing page. Best I have seen in a month. Bravo

#674I'm currently building a prototype hardware component (essentially a large format touch screen) that people can purchase alongside.

#676Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

#677Building https://fallinorg.com/ , a Mac app that organizes your files. It looks inside each file to see what it’s about, then moves it to the right folder for you. Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers. It already works with PDFs, text, Markdown, and many other file types. Next I’m adding ePub, and later Microsoft Office and iWork support. If you have messy folders any…
I pride myself on being pretty well organized with my digital life, especially files and folders. I’ve been using Hazel (God Knows, since it's beta). Recently, I realized it has become a muscle memory for me to name/rename files, and drop them where they belong while I'm working on or as it happens. This works for me now because I have a weekly routine of digital chores that picks up any slack and missing things that…
You’re right, Fallinorg currently only supports Apple Silicon Macs. The main reason is that the M-series chips have neural engines and very high memory bandwidth, which makes the AI models run fast and efficiently. On Intel Macs the performance just isn’t the same, but I do want to explore ways to bring a great experience there too. If you’d prefer a refund in the meantime, just let me know and I’ll send it right away — no worries at all.
Also, thank you for pointing out the email confirmation — I’ll definitely add that.
I noticed you mentioned using Hazel for years and building up muscle memory with rules. Right now, Fallinorg is built around content-based AI classification rather than rules. But rules can give a lot of precision and flexibility. Could you share what kind of rules or workflows you relied on most with Hazel? That would help me understand how people like you used it, and how Fallinorg might evolve to cover those use cases better.
Again, really appreciate your support and feedback.

#678The ideas are in large part inspired by Better-Auth, which is built on top of similar primitives. I hope more libraries will be built in this manner, because I believe that it provides very nice DX for the integrator/end-user.
It's not quite ready yet, but I did write most of the documentation.

#679Tritium, the integrated drafting environment for lawyers: https://tritium.legal/ Rust cross-platform application leveraging egui. Web preview: https://tritium.legal/preview
I always wondered what lawyers use for version control. They probably don’t call it that, but they must have a git equivalent in their world, right?

#680None of my clocks tell the time.
They're all fully automatic GPS-enabled timepieces. For a couple of years I've been developing, hand-making, and selling these clocks that track the moon phase, the sun's position, etc.
My new idea is the tide clock "NautiKron." It's getting a lot of interest from US coastal buyers.
