This project would not have been possible without the work of many people who contributed to the Open Source Software mentioned below.
Operating system is not mentioned for the security reasons (there are too many attacks a day to make it easier for the attackers) but the guys who wrote the system know well.
- Apache web server
- MariaDB database
- PHP scripting environment
- and plenty of other minor packages not mentioned specifically
And last but not least, without its contributors.
