Tool needed: uhubctl Github: https://github.com/mvp/uhubctl For Linux or Macos, sometimes we need to turn off  a usb device from command line. This is very useful when there is a faulty device but hard to remove or when testing certain usb devices. For linux, please refer to the Github readme for installation. For Macos, we can install uhubctl using brew: brew tap mvp/uhubctl https://github.com/mvp/uhubctl brew install uhubctl     To list all the current usb devices, use the command: uhubctl To turn of a certain device, use the following command: uhubctl -l {location} -p {port} -a off The {location} means the hub number (e.g. 1-1, 2-2, 2-1, etc.). The {port} means the port number. In the example above, the {location} is 1-1 and the {port} is 3.

 'brew services start <service name>' sometimes will claim it 'successfully' started a service even though it didn't. And it won't give you any log. However, we can use the command 'brew services list' to find the coresponding plist file and manually execute the service start command in that file. By doing this, the error can be print out.

WordPress sites administrators often encounter a problem - zombie or fake users register to your site using fake Emails. The emails they use often strictly follow the Email format so it's hard for our program to judge if they are valid or not.

As a result, an Email whitelist is needed to filter these annoying registrations. Geek Mail Whitelist is a plugin which can allow users with certain emails to register to your WordPress site by adding whitelist rules. What's more, it supports regular expression rules which makes it more powerful to fit all kinds of situations. And it is COMPLETELY FREE!
