The problem I kept seeing: defense contractors would spend months preparing for a CMMC assessment — policies, screenshots, control mappings, the whole thing — and then the C3PAO would ask who last modified a document and when. No audit trail. Assessment over. About 15–30% of first-time CMMC assessments fail. I'd guess a big chunk of those aren't failing because the security controls aren't in place. They're failing because there's no way to prove the evidence is authentic. So I built Solymus. Every artifact you upload gets SHA-256 hashed, signed with KMS (ECDSA_SHA_256 — signing the digest, not the payload, because of the 4KB limit), and sealed into a daily Merkle chain. Each artifact gets a public /verify/{id} endpoint — no auth required — so the assessor can check it themselves. One thing worth knowing: right after upload, merkle_status shows "pending". It upgrades to "linked" after midnight UTC when the attestation job runs. The KMS signature is valid immediately — Merkle is the additional daily seal. Took me a while to realize I needed to document that clearly or people assumed it was broken. Free tier at prolixotech.com. Happy to go into the crypto implementation if anyone's curious.

The car was designed for Gran Turismo, but the company built a real one. I got to see it in the flesh.

If you're looking for a new game to add to your collection, this one is down to just $33 -- a record-low price.

The exploding cost of RAM may contribute to a rise in PC prices, eliminating the category of computers under $500.

New analysis shows that attacks on satellite navigation systems have impacted some 1,100 ships in the Middle East since the US and Israel attacked Iran on February 28.

A higher-end mixed reality headset coming later this year wants to be a work device to rival Apple Vision Pro and Samsung Galaxy XR. It's got the power for it.

Hi HN,

I built Product Model, an open-source MDX-based grammar that gives product specs the same rigor as code — typed blocks, validation, version control, and a JSON AST output.

The problem: product intent lives in Google Docs and Notion. Implementation lives in code. Between them there's no structured layer, so requirements drift, edge cases disappear, and "that's not what I meant" becomes the most expensive sentence every sprint.

I wanted something more natural than code but more structured than a Google Doc — a format that both humans and AI agents can read, write, and reason about. That's what led me to build this.

Product Model lets PMs author .product.mdx files using blocks like Feature, Policy, Logic, Definition, and Constraint. Tooling validates the grammar, checks cross-references, and builds a machine-readable AST. Think of it as a type system for product requirements.

It comes with a CLI for validation and builds, and a visual Studio editor so you never have to touch raw MDX if you don't want to.

Would love feedback on the grammar design and whether this matches real PM workflows you've seen.

These are the best laptops my colleagues and I have reviewed from basic models to high-powered gaming systems and everything in between.
