shred - Securely delete files in Linux

Post date: January 24, 2010, 06:01 Category: Security Views: 5004 Comments
Tutorial quote: In case you want to delete some confidential data from your computer just to make sure that it is no longer accessible to anyone, then do not delete the file using the regular rm command because there will still remain a chance that someone might use a software to recover your deleted data before the specific storage area is overwritten by new data. The proper way to permanently dispose of such data in Linux is the shred command.

Xen Virtualization and Linux Clustering, Part 1

Post date: January 21, 2006, 06:01 Category: System Views: 4273 Comments
Tutorial quote: Have you heard about Xen virtualization and want to get some hands-on experience? Do you want to experiment with Linux clustering but only have a single computer to devote to the cause? If you answered yes to either of these questions, keep reading.

In this article, I briefly introduce the concepts of Xen virtualization and Linux clustering. From there, I show you how to set up multiple operating systems on a single computer using Xen and how to configure them for use with clustering. I should point out that a cluster implemented in this manner does not provide the computational power of multiple physical computers. It does, however, offer a way to prototype a cluster as well as provide a cost-effective development environment for cluster-based software. Even if you're not interested in clustering, this article gives you hands-on experience using Xen virtualization.

Benchmarking BSD and Linux

Post date: June 18, 2005, 22:06 Category: Benchmarks Views: 4340 Comments
Tutorial quote: These benchmarks are the result of my scalable network programming research. My interest in this area is to see how scalable and fast network applications can be on standard PC hardware.

I have done most of my research on Linux 2.4, 2.5 and 2.6 kernels using a home-grown distribution I affectionately call "Leanux". I have experimented with several APIs and methods to try and get the most scalability and performance out of a web server. The ultimate goal, however, is to demonstrate scalability by surviving a Slashdotting.

Changing Desktop Appearance On Linux Mint 11 (Advanced)

Post date: October 13, 2011, 07:10 Category: Desktop Views: 4898 Comments
Tutorial quote: This tutorial is supposed to show you how to change the GNOME desktop appearance on Linux Mint 11 further than the standard options of the Appearance section in the Control Center allow. I am going to use several different applications for this cause. This is the standard desktop that comes with Mint, so if you have not changed anything about that all steps should work fine for you. Be aware that the use of the nVidia proprietary drivers may not be unrisky!

Post date: May 14, 2007, 23:05 Category: System Views: 4040 Comments
Tutorial quote: Have you ever wished you had another computer handy? Maybe you want to try a new operating system out. Maybe you want to test something experimental without potentially breaking your own system. Maybe you need to run some software that only runs in a different operating system. Mandriva Linux 2007 Spring comes with a range of virtualization options that can help.

Using MySQL to benchmark OS performance

Post date: April 12, 2005, 07:04 Category: Benchmarks Views: 4132 Comments
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6
