How to compress PDF using ghostscript

As a developer, it bothers me when someone sends me a large pdf file compared to the number of pages. Recently, I recieved a 12MB scanned document for just one letter-sized page... so I got to googlin, like I usually do, and found ghostscript!

to learn more abot ghostscript (gs): https://www.ghostscript.com/

What we are interested in, is the gs command line tool, which provides many options for manipulating PDF, but we are interested in compressign those large PDF's into small yet legible documents.

XAMPP - Replace MariaDB with MySQL

Since XAMPP 5.5.30 and 5.6.14, XAMPP ships MariaDB instead of MySQL. MariaDB is not 100% compatible with MySQL and can be replaced with the "orginal" MySQL server.

Backup

• Backup the old database into a sql dump file
• Stop the MariaDB service
• Rename the folder: c:\xampp\mysql to c:\xampp\mariadb

// Help needed: I failed to send a value to the text resize and to apply it. Any idea ?

// to install this script: install the violentmonkey extension. Then click on "raw" on this github page.

// *perso note:
    //to install or to send update:
    // 1/ edit must be done on github (cf. the url in the tab settings).
    // 2/ Edit/update the script (using the edit github button) + increase the version (or it will ask to reinstall in the next step)
        // (don't need to increase the version if the change are just for myself: just reinstall it to keep the version)
    // 3/ click on RAW (it will show the changes).
