hbcondo714on Ask HN: What are you working on? (April 2026) (Non AI)

I'm building this site to display behavioral therapy data better for parents / caregivers. The site itself is just Next.js but the essence is ETL and data visualizations using the Observable Framework[1]. There is an opportunity to apply AI for Q&A.

hbcondo714on Show HN: GrobPaint: Somewhere Between MS Paint and Paint.net

Great effort and reason to create this! I'm accustomed to using the Magic Wand tool in Paint.net[1] and Pinta[2] to select pixels based on color. Any chance you could add that functionality?

hbcondo714on Ask HN: Have you successfully treated forward head posture ("nerd neck")?

Interesting, I’m glad you shared this as I had to lookup what a Rolfer is and came across Wikipedia’s very critical article concluding that there is no good evidence that Rolfing is effective for the treatment of any health condition

https://en.wikipedia.org/wiki/Rolfing

But other sites aren’t so critical but still conclude more research is needed to better understand the safety and risks of Rolfing https://health.clevelandclinic.org/rolfing-massage-benefits

Regardless of the conclusions, it still sounds like a conversation worth having with my physician.

Thanks for sharing this! I had done a PWA that displays some revenue forecasting[1] based on Stripe Subscriptions but I found their APIs can be slow[2]. Having that data synced up in a db sounds like a good enhancement so will definitely look into this more.

hbcondo714on Ask HN: Any example of successful vibe-coded product?

https://behavior.today

I cloned Paddle's NextJS starter kit[1] and incorporated my previous reporting code built with Observable Framework[2].

It actually took longer to get the website (domain, terms, privacy) approved by Paddle and my identity verified by its 3rd party than to vibe code the site with Claude Code.
