  1. Pick your JWT algorithm based on tradeoffs: HMAC (HS) is very fast and simple but uses a shared secret and cannot provide non-repudiation, while asymmetric algorithms let you separate signing and verification.
  2. Prefer modern asymmetric schemes when possible: RSA-PSS is safer than old PKCS#1 v1.5, ECDSA gives small fast signatures but demands perfect nonce randomness, and EdDSA (Ed25519) is usually the best choice because it’s fast, secure, and uses deterministic nonces.
  3. Match algorithm to your environment and tooling: RSA has the widest compatibility but large signatures and slower signing, ECDSA risks come from RNG mistakes, and EdDSA may require checking HSM/KMS and library support before committing.

Minimal Modeling 202 implied HN points 12 Jan 26
  1. Model joins by attaching a nested dataset to each outer row and then flattening by duplicating the outer row for each inner row; if the inner set is empty you skip the outer row for INNER JOIN or replace it with a single NULL row for LEFT JOIN.
  2. The inner part of a query becomes very simple: INNER JOIN is just a filtered SELECT, GROUP BY is an aggregated filtered SELECT, and LEFT JOIN is a filtered SELECT plus a conditional UNION ALL NULL row, so no special-casing is needed.
  3. Splitting queries into an outer table and a per-row inner dataset gives a clear, teachable mental model and a single canonical flattening rule you can reuse to reason about more complex SQL patterns like correlated subqueries.
