Cache have limited space.. they store in RAM, and it is volatile.. once you restart the server, all data will be gone

[Elijah 🌊 @juiceboy_of_abj]

If Cache is faster than database, then why do we need database?

Isn’t that normal?

[Coder girl 👩‍💻 @dev_maims]

I saw a girl coding today.

No Codex.
No Cursor.
No OpenCode.
No Claude Code.

She just sat there, typing code manually.
