#732I’m working on Userdoc, a spec-driven development workspace.
Break down your software requirements (Userdoc guides you through the process), refine/confirm, setup your technical specs, coding/business guidelines & guardrails, and then create development plans (specs) which can be easily consumed by coding agents via MCP, or by platforms like Lovable / v0 using Markdown. Working on Cursor background agent integration atm.

#733A couple of months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?” Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?” Turns out not that hard. In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless…
https://penneo.com/ is a good alternative. And while I applaud your effort to do something in this space, personally I'd prefer a solution that's been thought over by lawyers, etc. Faster is not better in this particular space.

#734I'm building a local medical AI app for Mac, recently published on the App Store. https://apple.co/4mlYANu
It uses medgemma 4B for analyzing medical images and generating diagnostic insights and reports, ofc must be used by caution, its not for real diagnostics, can be something to have another view maybe.
Currently, it supports chat and report generation, but I'm stuck on what other features to add beyond these. Also experimenting with integrating the 27B model, even with 4bit quantization, looks better than 4b.

Interesting! Can you share how hard it is to use the MS store for distribution? And is it worth it / does it bring in a good amount of business?

#737Building a hexapod, my first robot project ever, harder than I thought. I thought that kinematics will be the hardest thing…currently struggling with Euler Angles, Bezier's Curve and all those wonderful things

Really nice app design. For us outside the US, what is the use case for this? I don't think I've seen a paper check in over twenty years.

#739Currently a one-man side project: https://laboratory.love Last year, PlasticList found plastic chemicals in 86% of tested foods—including 100% of baby foods they tested. Around the same time, the EU lowered its “safe” BPA limit by 20,000×, while the FDA still allows levels roughly 100× higher than Europe’s new standard. That seemed solvable. Laboratory.love lets you crowdfund independent lab testing of the specific p…
This is very cool.
Here is something I'm struggling with as a user. I look at a product (this tofu for example [0]) and see the amounts. And then I have absolutely no clue what it means. Is it bad? How bad? I see nanograms one place and μg in an info menu - is μg a nanogram? And what is LOQ? Virtually 0? Simply less than the recommended amount?
I think 99% of people will have the same reaction. They will have no idea what the information means.
I clicked on some info icons to try and get more context. The context is good (explains what the different categories are) but it still didnt help me understand the amounts. I went to "About" and it didnt help with this. I went to the FAQ and and the closest I can find is:
>What makes a result 'concerning'? We don't make safety judgments. Instead, we compare results to established regulatory limits from FDA, EPA, and EFSA, noting when products exceed these thresholds. We also flag when regulatory limits themselves may be outdated based on new research.
I understand that you don't want to make the judgement and it's about transparency and getting the information. But the information is worthless if people dont know what it meant.

#740This weekend I added a broken link monitor to https://SecurityBot.dev. It will scan a site and flag 400, 403, 404, and 500 HTTP status codes. Screenshot:
Next up: an MCP server so devs can pull data from SecurityBot's various monitors directly into their IDE.
