Recently I found that the server is very slow every time apt upgrade，The reason，There are still a lot of unused kernels that have to be regenerated every time，Encountered a problem while cleaning up，*Number matching does not take effect，You must manually enter the full kernel name each time to uninstall it。
Found after stepping on the pit，It turned out to be because I used zsh，and zsh The default is not supported * No. wildcard! It’s easy to turn on this feature，Find your zsh configuration file we ~/.zshrc [……]
One of the big benefits of using SwiftUI is that you can hot update the App like Flutter，UI code changed，Will be directly reflected in the simulator or the real machine，Greatly improve the efficiency of writing user interfaces，No need to change 1px，run，Various clicks，Then check the loop of effects。But it's too early to use SwiftUI，After all, there is still a lot of iOS 12 Equipment is running，Want to do popular software，That still needs to be supported。
Then，Is there any way to make UIKit The software written can also be used in real-time[……]
Moses official website actually has macOS Binary packageof，You don't need to compile them from source。But short，Since Moses developers no longer use Macs，So he can't update，This leads to a bug in the code of the latest version (4.0)，Make the binary file can not be used directly，The author said, "It's not difficult to compile from source anyway..."

It's been a while since Apple released the M1 chip device，Although I applied for DTK equipment at the first time，But for some reasons，Until Apple Recycles Equipment，I couldn't touch it myself。In short，The drop grid input method macOS still successfully supports the Apple architecture by blind typing，I.e. arm64，According to user feedback，The effect is ok。
Until some users say that although the app supports the m1 chip，But the installation package does not work-when running the pkg installation package，Rosetta 2 pops up...
Although it does not affect[……]
Recently, the drop grid input method has encountered several difficult to reproduce problems-the key is that it will not cause a crash。This makes the crash statistics function completely ineffective，The specific performance is that the input method will suddenly get stuck for a few seconds in some cases，Very annoying。Then I thought，macOS comes with activity manager，There is a "sampling" function，You can see the current execution (call) status of the corresponding process，Can I use it to analyze the cause of the error?
After communicating with users，I got a sampling report like this：
Python is a good thing，Many times we like to use it to write small things... For example, many services on my server are written in Python ( Supervisor will use your Python program becomes Services ），Accumulate，Many dependency packages are actually used。

Now if you want to bind a storyboard object to the code，All you may find are like this：
