Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things. Next addition will be to add health inspection data from countries that have that in open datasets or APIs, so if anyone know of that I'd be appreciative of…

Would be great to know which pubs have gluten free beer. I recently became gluten intolerant, and it's ended my 40 year beer career!

They are becoming more common, as it's very simple to make them GF- you can simply add an enzyme that eats up the gluten. Bristol Beer Factory's whole range is GF and very tasty (my local brewery).

I'm working on Small Transfers ( https://smalltransfers.com/ ), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers. You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets. If combined with subscriptions, the pricing can work similarl…

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?

> ultimately a PayPal remake?

Pretty sure you can't send tiny fractions of a penny through PayPal.

I’m building https://www.kidcarekit.com , a Rails SaaS for family-run daycare centers that still juggle spreadsheets and phone calls. It wraps waitlist management, enrollments, and Stripe billing into a single dashboard with Tailwind + Hotwire on the front, Devise for auth, and Azure Blob for logos. Solid Queue handles scheduled jobs like weekly tuition and late fee automation so owners get predictable cash flow with…

Looks like a hell of a lot of value for $15 / month.

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…

Accuracy indicators for rushing and dragging are very useful, but equally interesting would be an indicator that checks for a consistent peaks, so every note is played with equal volume. A dream would be if your app can detect differences in sound (fingernails occasionally scratching the string, fretbuzz). Is there any way to get notified when your app is done, or do you have a name for it already so we can search fo…

Love those ideas, would be awesome for really nailing down consistent tones. Latter one would be fairly ambitious for me but I'll keep it in mind for future improvements.

Just published the waitlist[1], the app will be called ShredBlocks.

I love the idea of a free and a distributed/decentralized social media, I have just been trying to come up with some basic arch for it. This is not the final direction I want to go with this, can pivot based on interests. i am open if anyone is interested in joining!

Oh man, I am extraordinarily late to this.

I built a fairly sophisticated Discord bot called Musebot that integrates with both Ollama and ComfyUI: https://xcjs.com/discord

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…

So a Shaper Origin for bone cutting? Pretty neat!

Great analogy!

I'm launching a new product for my clock-making business: https://DigitalHorology.com None 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.

NautiKron seems to show the current hour in the top row. Why not project it on the tide curve?

Putting the marker inside the tide curve would give it a cleaner look.

I considered it, and figured it was more legible to have the hour marker directly under the numbers. People looking at the NautiKron from across the room or who have low vision might like it better this way.

Good idea to revisit -- I'm always tweaking the designs and responding to owner feedback.

Thanks for the comment!

Currently 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…

I suggest you xpost to Bryan Johnson's Blueprint community. I think might help you get a lot more food tested. That community is probably ICP and also can amplify the message.

Blueprint is doing exactly this. I got my cat’s food tested there.
