A (Mostly) Complete Guide to React Rendering Behavior

Bài viết cung cấp chi tiết về cách mà React render hoạt động, và việc sử dụng Context và Redux ảnh hưởng thế nào tới quá trình render của React.

"Render" là gì

Rendering is the process of React asking your components to describe what they want their section of the UI to look like, now, based on the current combination of props and state.

How-to

On Host(PVE), edit /etc/pve/qemu-server/VMID.conf

args: -fsdev local,security_model=mapped,id=fsdev0,path=/path/to/share -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare

This tells qemu to create a 9pvirtio device exposing the mount_tag hostshare (just a name to identify the mount point). That device is coupled to an fsdev named fsdev0, which specifies which portion of the host filesystem we are sharing, and in which mode.

A Way to Look at Tideman Lock Pairs

I've observed that there is a little bit of a disconnect in understanding what it is that needs to be done to properly implement the lock_pairs function for cs50 Tideman. The goal of this little write-up is simply an attempt at explaining what the problem actually is, and why a cycle imposes a problem.

First:
If you are unfamiliar with the actual problem, or have not read through the entire cs50 Tideman problem description. Then I think you should start there.
cs50 Tideman

Second:
This little write-up is only narrowing in on the idea of cycles, and a way to think about what a cycle is and determine if locking a pair in the pairs array would create that cycle. This does not talk about any other part of the Tideman problem.
