Hacker Newsroom for 24 June recaps major Hacker News stories, moving through age verification, f3 file format, flock camera warrants, local glm 5 2.

1. Age Verification

The next story is a Pluralistic post arguing that what lawmakers call online age verification is really a mass-surveillance system, because proving age at internet scale means tying identity to browsing, expanding data collection, and setting up later moves like VPN bans. The post says the real way to protect kids is to stop the surveillance and recommendation machinery already shaping what they see, not to make privacy illegal in the name of child safety.

2. F3 File Format

The next story is F3, a GitHub research project for a next-generation columnar data format that aims to improve on Parquet and ORC by reorganizing storage layout and embedding WebAssembly decoders so older readers can still open newer files. The project explicitly describes itself as a research prototype, and its main claim is that this approach could make data formats more extensible and forward-compatible without forcing constant rewrites.

3. Flock Camera Warrants

The next story is about a report arguing that Flock license plate reader systems should require warrants after multiple police chiefs were accused of using them to stalk former partners and rivals. The article says those cases show the company’s claim that it tracks vehicles rather than people breaks down in practice, and it argues that warrant-based access would still leave room for real emergencies under existing exceptions.

5. Canada Nuclear Buildout

The next story is about Canada’s planned nuclear renaissance, with a CBC news story reporting that the federal government wants up to 10 new reactors built by 2040, alongside more uranium exports and a bigger push to sell Canadian reactor designs abroad. The article says Ottawa wants construction started on two large reactors by 2035, at least one reactor underway outside Ontario by then, and a remote-community microreactor later in the decade, even though the overall buildout could cost more than 100 billion dollars and the funding path is still vague.

6. Unlimited OCR

The next story is Unlimited OCR, a new GitHub project from Baidu that says it can parse long documents in one shot by keeping full visual access to the original pages while limiting how much generated text it remembers, which is meant to cut memory use and avoid the page-by-page stitching that makes OCR pipelines slow and brittle. The post positions it as a way to push OCR beyond short snippets and toward long PDFs, with code for local GPU inference, batch processing, and an OpenAI-compatible serving setup.
