How do you disable browser Autocomplete on web form field / input tag?

How do you disable browser Autocomplete on web form field / input tag?

Firefox 30 ignores autocomplete="off" for passwords, opting to prompt the user instead whether the password should be stored on the client. 

  • The password manager always prompts if it wants to save a password. Passwords are not saved without permission from the user. 
  • We are the third browser to implement this change, after IE and Chrome.

According to the Mozilla Developer Network documentation, the Boolean form element attribute autocomplete prevents form data from being cached in older browsers.

<input type="text" name="foo" autocomplete="off" />

How do I get a YouTube video thumbnail from the YouTube API?

How do I get a YouTube video thumbnail from the YouTube API?


Each YouTube video has four generated images. They are predictably formatted as follows:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg
https://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg
https://img.youtube.com/vi/<insert-youtube-video-id-here>/2.jpg
https://img.youtube.com/vi/<insert-youtube-video-id-here>/3.jpg

The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (i.e., one of 1.jpg, 2.jpg, 3.jpg) is:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg
For the high quality version of the thumbnail use a URL similar to this:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg
There is also a medium quality version of the thumbnail, using a URL similar to the HQ:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg
For the standard definition version of the thumbnail, use a URL similar to this:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/sddefault.jpg
For the maximum resolution version of the thumbnail use a URL similar to this:

https://img.youtube.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg
All of the above URLs are available over HTTP too. Additionally, the slightly shorter hostname i3.ytimg.com works in place of img.youtube.com in the example URLs above.

How to enable Intel VT-X or Intel virtualization technology from BIOS.

How to enable Intel VT-X or Intel virtualization technology from BIOS.

If you have encountered the error such as “"This hosting support Intel vt-x, but Intel VT-x is disabled" or – “This virtual machine is configured for 64-bit guest operating systems. 

However, 64-bit operation is not possible” while installing Virtual Machine in VMWARE. 

 In such a case, you have to enable intel virtualization technology from BIOS in order to install a virtual machine.

In my case, I am using HP Laptop and the key to enter the boot menu is ESC. It can be different for different manufactures. You can check for your computer. Sometimes it’s written at the bottom while system boots.  

Steps :
1. Reboot your computer and press the relevant key in order to enter into BIOS. 
2. Scroll different options using the keys written at the bottom.
3. Locate for VIRTUALISATION TECHNOLOGY. For my laptop, it was under system configuration.
4. Select VIRTUALISATION TECHNOLOGY,  Hit enter and choose enabled from the drop-down menu. 7. Save the settings before you exit. Now, try to install the virtual machine and you will be able to install any windows on VM Ware.

How Do I Make a JSON Pretty Printer App Using PHP for Development/Debugging Use as a Coder?

How Do I Make a JSON Pretty Printer App Using PHP for Development/Debugging Use as a Coder?
You'll know you don't wanna publish your app's JSON response, which may include important information, to some third-party website that could easily or accidentally log this info. I think, decrypted passwords might be in your response, API keys, the name of your app. Lots of stuff can't nobody but you should see. So here, make your own JSON PRETTY PRINTER using PHP and RUN IT LOCALLY on your computer.

<?php
$str = <<<'EOT'
{"name_first":"John"}
EOT;
echo json_encode(json_decode($str), JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);
?>

Save the file. Name it something such as json-pretty-printer.php and then run it on the command line by typing 'php' then the path to your script. Hit the enter button.
