Things Every Engineer Should Know: SQL Execution Order.

Two ways to keep a user logged in.

And they fail in very different ways.

After login, you need to remember who the user is.

There's typically two common approaches:
• Session token: a random ID. The server stores the session and looks it up each request.
• JWT: a signed token holding the user's info. The server just verifies the signature, no lookup.

JWTs scale well because there's no server-side storage. That's also their weakness.

This is because you can't easily revoke a JWT before it expires. A logged-out user's token still works until it times out. Sessions you can kill instantly.

The solution, which is still not ideal, for JWTs is short expiration and token blacklisting.

Stateless is convenient, but "can't revoke" is a real security tradeoff.

Django 6.1's tip Fetch Modes: #python #django #fetch_modes

Django 6.1 fixes N+1 without you rewriting your queries you never touch the for loop. You just tell the queryset how permissive it should be about surprise trips to the database — and FETCH_PEERS quietly turns "101 queries" into "2 queries" with zero extra code at the call site.
