Problem: When using SSH to connect other server, I don’t want to type passphrase everytime:)
For Windows 10 you need PowerShell to active ssh-agent in order to save passphrase.
Solution: First use Administrator right to open PowerShell (Windows PowerShell).
Then enter below command to active ssh-agent:
local Administrator PowerShell Set-Service ssh-agent -StnartupType Automatic Start-Service ssh-agent Get-Service ssh-agent
Then now you can add the key file (My file store in C:\Users\user.ssh\id_rsa), it will prompt a message to obtain the passphrase.
ssh-add C:\Users\user.ssh\id_rsa (Enter your passphrase)
Eventually, ssh-agent will store your passphrase now. You can also enter
ssh-add -l
to check out the record.

Problem: Want to detect a tag like <div>, when it removed, do something.
Solution: Based on this answer, we can use ‘on’ to detect event like‘remove’:
keep in mind that you must add jQuery (v1.9.1 or above) and jQuery UI -(v1.10.2 or above) scripts in it.
For example, I want to detect a tag with class name “test”:
<div class="test">already to vanish</div>
in the jQuery script part, add below code:
$(".test").on("remove", function () {
alert("Element was removed, do something");
})
Problem: As the title stated, the form submit function not working because of the required field that user forgot to fill, and the field itself is hidden like below code:
<input type="hidden" required name="form_field" >
so the solution will be adding the value into that hidden value.
Problem: Having two collections/MySQL query results and combine them using union():
$result1->union($result2);
then want to remove all duplicate on that union result.
Solution: using unique() to remove duplicates. You can add a parameter like unique(‘id’) to specifically remove which tag name. Example:
$result1 = $result1->unique()->values()->all();
Remember to assign it to a variable or else it will remain the same.
