The fstab file (located in the /etc directory) controls how Linux provides access to the partitions on the hard disk.

The SmokePing Project can measure, store and display latency, latency distribution, and packet loss. SmokePing uses...
PHP has a slightly turbulent history of packet management. This was to change in early 2012, when Composer and his brother, Packagist, were launched. A package management system did not exist in the PHP world until early 2000, when Stig Bakken started the PEAR project as a result of the Tel Aviv talks at the PHP Developers Meeting. The operating principle of the PEAR was to incorporate a manager...
