macOS third-party input method debugging method

Mac OS Exchange of Experience R0uter Input Tool

macOS has been updated to 26 It's， But there has been no change in support for third-party input methods，Latest Xcode 26 Destroyed the method I had been using before - directly changed the compilation path to /Library/Input Method If you do this now, xcode will report an error，Because the framework the project depends on will no longer be written to this directory.。

Only after removing all settings that change the compilation directory can the compilation be successful.。My guess is that the new version of SPM no longer follows the Xcode project output directory.[……]

The internet

So far，Very few operators are willing to give you public IP for free anymore.。 CGNAT It has long been the norm，Of course, on the bright side，At least it hides your real IP，Protect your home router/NAS from direct hacker attacks to a certain extent。

How to redirect old domain names

Linux The internet

Sometimes we need to redirect access to another domain name，For example, when the old domain name is walled。

Some domain name providers provide this service，But the functions are very basic，Only simply match the domain name and then jump，And this jump will lose parameters and other information，Or simply fail to match，Basically unusable。

To redirect the domain name and retain the request parameters，You need to have a dedicated server to accept the request and return the redirect information。This requirement cannot be achieved simply by DNS。

Using a server

If your ISP assign u IPv6 only a prefix but no address

I recently switched Internet provider，The new provider offered me a /48 address prefix，This is different from my previous operators，They mostly use DHCP，Allocate one to you directly IPv6 the address of。Although the meaning of v6's existence is that the address is "infinite"，But assigning one can save a lot of configuration trouble.。

This new setup caught me off guard。
