Using JWT to establish a trusted context for Row Level Security

news.ycombinator.com Unknown 2025-10-12 22:32:51

Row-level security (RLS) is a great feature. It allows restricting access to rows by applying filters defined by a policy. It’s a tool useful for cases when the data set can’t be split into separate databases. Sadly, using RLS may be quite cumbersome. RLS requires some sort of “trusted context” for the RLS policies. The policies need to filter using data the user can’t change. If the filter uses some sort of “tenant ID”, and the user can change it to an arbitrary value, that would break the RLS

“This telegram must be closely paraphrased before being communicated to anyone”

It appears that it was US military communications doctrine to not send the exact same message twice using different encryption ("none" counting as one type of encryption), and the term of art for changing a message to avoid that was indeed "paraphrase". I managed to dig up a US Army document on Cryptology from roughly that era that appears to discuss paraphrasing.

Meta seems to be working on ways for Threads users to share long-form writing within a single post. Several users have reported seeing a new "attach text" feature on the service, which allows them to embed large chunks of text within a single post.

The first idea resembling something like the idea of OCR got developed in 1870 as a reading machine for the blind - the Optophone. This was the first step to solve a problem that sounds pretty simple: How do we get writing on paper inside a computer? 150 years of research, engineering breakthroughs and hundreds of IDP products later we were finally able to scan a receipt and have the fields be filled out - if it looked nice and friendly enough to the OCR model.
