git log -S finds when a string appeared or vanished

git blame tells you who last touched a line. git log -S tells you every commit where the number of occurrences of a string changed, which is the question "when did this constant become 30" actually is.

git log -S "MAX_RETRIES" --oneline -- src/

Add -p to see the diffs. It is the fastest archaeology tool in git.

Session cookies: HttpOnly, Secure, SameSite=Lax

securityhttp

Three attributes, each closing a class of attack. HttpOnly keeps scripts from reading it. Secure keeps it off plain HTTP. SameSite=Lax stops it being sent on cross-site POSTs, which is most CSRF.

Set-Cookie: session=...; HttpOnly; Secure; SameSite=Lax; Path=/; Max-Age=1209600

Strict breaks arriving from an external link while logged in. Lax is the default worth keeping.
