Debian Setting Up Master-Master Replication With MySQL 5 On Debian Etch
Post date: October 25, 2007, 06:10 Category: Miscellaneous Views: 1183 Comments: 0
Tutorial quote: Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you do not have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.

Debian Little-known APT utilities for Debian desktop users
Post date: July 30, 2006, 13:07 Category: Desktop Views: 970 Comments: 0
Tutorial quote: The Advanced Packaging Tool (APT) is a distinguishing feature of Debian-based systems. APT was the first major alternative in GNU/Linux to boast automatic dependency resolution. Most GNU/Linux users know it through the apt-get command, a utility that calls on the lower-level dpkg command. However, other APT-based utilities remain largely unknown to desktop users. Some of these utilities offer a range of functionality far beyond those of the basic tools.

Post date: April 20, 2009, 04:04 Category: Security Views: 833 Comments: 0
Tutorial quote: Almost without exception, today's Internet users prove their identity online using a fixed account name and password. In the past, this simple system provided sufficient security. But with the growing popularity of online banking and eCommerce, the value of stealing online identities has skyrocketed. And the increasing presence and "spyware" and "malware" on innocent users' computers means that users can be "watched" while logging onto their banking and other eCommerce sites.

Unix+clones Emulating an OS with qemu
Post date: May 22, 2005, 03:05 Category: Emulation Views: 2082 Comments: 0
Tutorial quote: When you want to emulate a PC with a complete operating system on your computer, the most heard answer would be VMWare. Sure, for Linux, there is wine, but that package is targeted to handle only window$ and not all programs are supported. No, I'm talking about simulating a complete OS on a virtual PC with virtual hardware.

Although VMware does an almost perfect job at it, it isn't free software. Time to see what the Open Source community has to offer. That's when I stumbled upon qemu. Let's have a look at the possibilities.
