Version control for non-programmers with Subversion

Post date: June 9, 2005, 04:06 Category: Software Views: 3492 Comments
Tutorial quote: Imagine a utility that lets you make an annotated backup of any of your project files with the click of a mouse or a single command. It would let you review the history of your backups and recover any version you wished. And it would integrate with your file browser and would keep track of files that have changed since your last backup. The utility exists -- Subversion, and its companion program TortoiseSVN, can help you safely manage your files as you work with them.

Enhance boot-time security with GRUB passwords

Post date: April 26, 2006, 13:04 Category: Security Views: 3488 Comments
Tutorial quote: The security of data files on your computer is at risk, and not just because you are connected to the Internet. Anyone with physical access to your machine can bypass all passwords to gain entry to your hard disk with one simple command given to the bootloader. Fortunately, the popular GRand Unified Bootloader (GRUB) is equipped with security features to prevent such an 'attack.' It can password protect each entry of your boot menu.

Encrypt-Decrypt files using mcrypt on OpenSuse

Post date: January 27, 2009, 07:01 Category: Security Views: 3898 Comments
Tutorial quote: MCrypt is a replacement for the old crypt() package and crypt(1) command, with extensions. It allows developers to use a wide range of encryption functions, without making drastic changes to their code. It allows users to encrypt files or data streams without having to be cryptographers. Above all, it allows you to have some really neat code on your machine. :)

The companion to MCrypt is Libmcrypt, which contains the actual encryption functions themselves, and provides a standardized mechanism for accessing them.

Command your network with Kaboodle

Post date: June 28, 2005, 09:06 Category: Network Views: 3637 Comments
Tutorial quote: Quite often setting up a local network is much easier than managing it. Even technically challenged users can figure out how to connect a couple of computers and a printer. However, tasks like maintenance, troubleshooting, and remote secure connections require more than just "which-cable-goes-where" knowledge. You need something like Kaboodle, a nifty tool that can help you to manage your local network like a pro.

Kaboodle allows you to visualize your local network, control computers on it via VNC, and connect to other Kaboodle-enabled networks. Kaboodle was developed for Windows, but according to its Web site, it will happily run under Wine on Linux and FreeBSD.

Tutorial quote: Suppose you have a 40GB hard disk and a removable hard disk whose capacity is 60GB, and you want to backup all the files from the hard disk to the removable disk. With "dd", it is a very easy task. Again, suppose your hard disk's Unix device name is /dev/sda and the removable disk is /dev/sdb. The following command can copy all the content from /dev/sda to /dev/sdb:

How To Set Up Database Replication In MySQL On Ubuntu 9.10

Post date: January 12, 2010, 12:01 Category: Miscellaneous Views: 3319 Comments
Tutorial quote: This tutorial describes how to set up database replication in MySQL. MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures.

How To Install Qmailtoaster (CentOS 5.3)

Post date: June 19, 2009, 10:06 Category: Installing Views: 7860 Comments
Tutorial quote: Qmailtoaster is a project that aims to make the installation of Qmail onto RPM based systems a snap. All of the packages are distributed in source RPMs so building the packages for your particular distro and architecture is as easy as running a script or a simple command for each package. The RPMs have all of the needed and commonly asked for patches included so you can have a mail server up and running in about an hour. When it's all complete, you'll have a full Qmail mail server installation ready for just about anything. I personally run Qmailtoaster servers for other companies and ISPs who have tens of thousands of users on their systems.

How to Install Latest Wine in debian Etch

Post date: December 22, 2008, 07:12 Category: Software Views: 3497 Comments
Tutorial quote: Wine makes it possible to run Windows programs alongside any Unix-like operating system,particularly Linux. At its heart, Wine is an implementation of the Windows Application
Programing Interface (API) library, acting as a bridge between the Windows program and Linux.Think of Wine as a compatibility layer, when a Windows program tries to perform a function that Linux doesn’t normally understand, Wine will translate that program’s instruction into one supported by the system. For example, if a program asks the system to create a Windows pushbutton or text-edit field, Wine will convert that instruction into its Linux equivalent in the form of a command to the window manager using the standard X11 protocol.
