Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics/circuits: https://circuitscript.net/ Recently, I have released a simple IDE (called the Bench) to try Circuitscript online: https://bench.circuitscript.net/ The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circ…

Hey I am a embedded sw / hw engineer. looks pretty neat. would love to talk to you about it

A webscraping / data pipeline to get the .pdf "Explanation of Benefits", "Proof of Coverage", and "Drug Formulary" for every Medicare Advantage plan in the USA

These docs are gonna be used in a product for medicare brokers (if you are/know one please reach out open enrollment starts Nov.1!), and the pipeline is horizontally scalable to ingest updated 2026 plans overnight @ start of open enrollment (though some companies are posting updated plans earlier)

There are some clever tricks at play but mostly it's bog-standard browser automation; I'm also in an interview process with 2 entities (one funded startup and one massive corporation) talking about web automation roles, and while it's frustrating that they're moving so slowly it's working out to give me time to build this well.

Looking at the tofu reports, I really don't know what to make of them. Is there a way to give more meaning to them for the average person? Also, I'd love to see a sort by "almost funded" option.

Second this, it would be useful to have a "EU safe" label or similar to help me understand if 635.8 DEHP is a good thing or bad.

Or "NON-GMO" label would very extremely helpful too.

I'm working on Typegres, a new data layer for the modern stack (TypeScript + PostgreSQL).

My take is that for years, ORMs have hidden the power of PostgreSQL behind generic, database-agnostic abstractions. This made sense in 2010, but now it's a bottleneck.

Typegres rejects this. It's a "translator, not an abstraction," designed to express the full power of PostgreSQL (all statements, built-in functions, etc.) in a type-safe TypeScript API.

The latest killer feature my take of "object-relational mapping done right": class-based models with methods that are actually composable SQL expressions. This lets you extend your tables with expressive logic and fully-composable relations.

It's easier to show than tell. Take a look: https://typegres.com/play

Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them.

Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods.

I'm making a visual explainer site for PyTorch functions: https://whytorch.org/ A great example of how it works is http://whytorch.org/torch.amax/ Clicking items in the tensors explains where they came from and where they are used in the output. The input tensors can be modified too. It's a one-man side project that's been half building the site framework, and half re-implementing pytorch functions in javascript. Ple…

This looks neat. Great idea! Perhaps `dot`, `cross` etc might be useful additions.

I've just added the dot, cross, and Kronecker products - thanks for the suggestion!

I've been sculpting a static site generator for myself in TypeScript. The focus is on accessible, clean, and semantic output. It's one of those endless projects but it's fun to work on.

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.

Thanks for the feedback. Yes, data readability is on the roadmap!

What would be a good strategy to prevent companies from cottoning on to this and gaming the system? They could for example change packaging on production runs for a product that’s undergoing laboratory.love funding campaign.

It's an interesting thought. Companies do change packaging somewhat regularly. However, the underlying skew usually remains the same. Changing the packaging and/or the SKU is very expensive. It's probably cheaper and more beneficial to your company to do your own Plastic Chemical testing and get ahead of the problem.
