vscode remote ssh Error: EACCES: permission denied
https://github.com/microsoft/vscode/issues/48659
1. make sure that sudo -u newuser -i works in a regular ssh session without requesting a password 2. remove “-o RemoteCommand=none” and “bash” from extension.js like so```
sed -i s/"-o RemoteCommand=none"/""/ ~/.vscode/extensions/ms-vscode-remote.remote-ssh-*/out/extension.js
sed -i s/“bash”/""/ ~/.vscode/extensions/ms-vscode-remote.remote-ssh-*/out/extension.js
3\. create an ssh config entry with a RemoteCommand like this one:
Host pi-for-newuser
Hostname pi
User pi
RemoteCommand sudo -u newuser -i

https://firebase.google.com/docs/hosting/manage-cache?hl=zh-cn#using_cookies
将 Firebase 托管与 Cloud Functions 或 Cloud Run 搭配使用时，Cookie 通常会从传入的请求中剥离出来。这是实现高效的 CDN 缓存行为所必需的。只有特别指定的 __session Cookie 可以传入应用执行过程中。 __session Cookie（如果存在）会自动成为缓存键的一部分，也就是说，使用不同 Cookie 的两个用户绝不会收到彼此的已缓存响应。只有在您的应用根据用户授权提供不同的内容时，您才能使用 __session Cookie。
System on firebase functions always have problems that code start.
