I have a lot of experience in participating in VSCode offline technology exchange activities, and my main gains include sharing of plug-in development, practical demonstrations and communication with other developers. 1. Sharing of plug-in development: I learned how to use VSCode's plug-in API to improve development efficiency, such as automatic formatting and static analysis plug-ins. 2. Practical demonstration: I learned how to use VSCode for remote development and realized its flexibility and scalability. 3. Communicate with developers: I have obtained skills to optimize VSCode startup speed, such as reducing the number of plug-ins loaded at startup and managing the plug-in loading order. In short, this event has benefited me a lot and I highly recommend those who are interested in VSCode to participate.

Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file
