TIL External links should not be "=_target"

POSTED ON: Jun 30, 2020

When you link to a page on another site using the target="_blank" attribute, you can expose your site to performance and security issues:

The other page may run on the same process as your page. If the other page is running a lot of JavaScript, your page's performance may suffer.

The other page can access your window object with the window.opener property. This may allow the other page to redirect your page to a malicious URL.

Adding rel="noopener" or rel="noreferrer" to your target="_blank" links avoids these issues.

TIL php-fpm

PHP runs as a separated service when using PHP-FPM. By using this PHP version as language interpreter, requests are processed through a TCP/IP socket; so that the Nginx web server only handles the HTTP requests and PHP-FPM interprets the PHP code. The fact of having two separate services is key for increasing efficiency.

TIL Considering Device Obsolescence with web development
