Using the document-ready event can have small performance drawbacks, with delayed execution of up to ~300ms. Sometimes the same behavior can be achieved by execution of code just before the closing </body> tag:
<body>

You can create a task (Console Command) in Laravel using Artisan. From your command line:
php artisan make:console MyTaskName
This creates the file in app/Console/Commands/MyTaskName.php. It will look like this:
<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
c...
When your command is made available to your application, you can use Laravel to schedule it to run at pre-defined intervals, just like you would a CRON.
In The app/Console/Kernel.php file you will find a schedule method that you can use to schedule your task.
<?php
namespace App\Console;
...
The scheduler can be run using the command:
php artisan schedule:run
The scheduler needs to be run every minute in order to work correctly. You can set this up by creating a cron job with the following line, which runs the scheduler every minute in the background.
* * * * * php /path/to/artisan...
The easiest method to bypass cache is to change the URL. This is used as a best practice when the URL contains a version or a checksum of the resource, e.g.
http://example.com/image.png?version=1
http://example.com/image.png?version=2
These two URLs will be cached separately, so even if …?versi...
It is common for an AsyncTask to require a reference to the Activity that called it.

If, however, the AsyncTask is not an inner class of the Activity, you will need to pass an A...

To setup every new branch to automatically rebase, add the following to your .gitconfig or .gi...
Copy foo.txt from /path/to/source/ to /path/to/target/folder/
cp /path/to/source/foo.txt /path/to/target/folder/
Copy foo.txt from /path/to/source/ to /path/to/target/folder/ into a file called bar.txt
cp /path/to/source/foo.txt /path/to/target/folder/bar.txt
copy folder foo into folder bar
cp -r /path/to/foo /path/to/bar
if folder bar exists before issuing the command, then foo and its content will be copied into the folder bar.
However, if bar does not exist before issuing the command, then the folder bar will be created and the content of foo wil...
