Turn on rerere before a long rebase

Rebasing a branch with twenty commits over main means resolving the same conflict several times. rerere records how you resolved it the first time and replays it.

git config --global rerere.enabled true

It is off by default for no reason anyone remembers. Turn it on once and forget it exists.

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.
