Today I am pleased to publish an interview with Gabriele, leader of the project SalentOS, as well as owner of the interesting blog gmstyle.org , in the past we exchanged emails and articles and today I want to write a little more information about him and his project.
At the base of these articles there is a simple fact: a simple rm of a file or deleting it via any file manager is not enough to really remove it from your hard disk.
If you really want to delete files from a computer you have to use more sophisticated commands, and in former articles we have seen:
Dban: Darik’s Boot and Nuke (commonly known as DBAN) is an open source project hosted on SourceForge. The program is designed to securely erase a hard disk until data is permanently removed and no longer recoverable, which is achieved by overwriting the data with random numbers generated by Mersenne twister or ISAAC (a PRNG).
Shred : Overwrites the specified FILE(s) repeatedly, in order to make it harder for even very expensive hardware probing to recover the data.
Wipe : Wipe is a secure file wiping utility.
Today we’ll take a look at the package secure-delete that contains some useful programs to delete in a safer way files, memory, free space and/or the Swap space. Continue reading »
Sometimes it’s useful to tell to our GNU/Linux system that we want to keep some packages on Hold or that we do not want to update them , for example you could have added a custom kernel and you don’t want that during an update the standard kernel takes its place, or perhaps you want to test some specific version.
These instructions are tested with distributions that use packages in the .deb format (such as Debian, Ubuntu and Mint), .rpm based distributions that use yum (Red Hat Enterprise, Centos, Fedora) and Gentoo.

This is an article of mine first published on Wazi
The mod_jk connector serves as the glue between the Apache HTTP server and a Java application server such as Tomcat or JBoss. While most adminstrators concentrate on optimizing Apache or the Java server, setting up mod_jk optimally can also improve your users’ experience.
To be precise, mod_jk connects the Apache web server to the AJP port of a Java server. Apache Jserv Protocol is a binary version of HTTP that is optimized for communication over TCP between the Apache HTTP server and Apache Tomcat or other software.
In a former article I’ve talked about the commands cron and crontab that are the standard way to schedule recurring things on a Gnu/Linux system.
But sometimes you need to do one thing at a specific date and time for just one time, and for these tasks the best option is to use at, another way to use at is to run a command later when the computer won’t be busy.
Or another reason could be that you want to run a command that requires a lot of time to end and you have to disconnect from that server, at could be used in this situation, but for these task i suggest to take a look at the articles on how to run commands on background and the utility screen
