After loading too many plugin in Photoshop, the filter in PS may exceed the height of the window, and there is a way to do it, though it's a bit tricky. PS4 has a new feature that can search subdirectories and even shortcuts in plugins directories and automatically mount them. With this feature, you can divide your own plugin into groups of directories, and to invoke a group of plugin, simply create a shortcut to that group plugin directory in the plu

1. Introduction to NFS(1) What is NFS?1) NFS is a shorthand for the net file system, which is the network filesystem. NFS was developed by Sun and launched in 1984 as an RPC (remote procedure Call) service system that enables us to share files and use them across different systems, so it has nothing to do with communication protocols, hosts, and operating systems. When a user wants to use a remote file, the remote file system can be hooked up to their file system using the "mount" command, so th

It's hard to know that you have to learn to do it for at least 3 months, and that part of the script is exhausting. I suggest that it would be better to learn the shell first, and then learn another scripting language after work.The above is to step into the Linux operations engineers need

You can take more steps to enhance the protection of the server. Keep in mind that it is your responsibility to keep your servers secure and make the best choice when maintaining your servers, although there is no easy way to do this, and building "perfect" security takes a lot of time and testing until you get the results you want.Free p

The small shared memory process gets the shared memory of the large shared memory process and modifies the size and content of its shared memory (note the following comment supplement), which can cause the large shared memory process to crash.Workaround:Method One:When all of the sh
