Wed, 18 Nov 2009 19:47:56 GMT ListGarden Program 1.3.1 http://blogs.law.harvard.edu/tech/rss http://www.linuxconfig.org/introduction-to-computer-vision-with-opencv-on-linux The purpose of this document is to help a reader to get started with Computer Vision library OpenCV on Linux system. OpencCV is a multi-platform library, but this article will be focused only on OpenCV using Linux operating system. Although, just the installation of the OpenCV library and video camera is platform-specific, all examples in this article should compile on any platform where OpenCV is properly installed ( Mac OS, MS Windows and etc.) . Reader will be guided through a step-by-step guide on how to install and use some of the basic functions of OpenCV library such as displaying images, playing a video or using a video camera to process a video input stream. Wed, 11 Nov 2009 01:18:42 GMT http://www.linuxconfig.org/c-understanding-pointers This article is intended to all programing enthusiasts on all levels who do wish to understand pointers in C++ language. All code presented here is not a compiler specific and all examples will be written in plain ANSI C++. Debate about pointers can stretch for miles, and you would need to go really far to master it all. If you really want to run that far, this article gives you a clear understanding of fundamental concepts about pointers and prepares you for that journey.

The article will deal with authentication of server (One-way SSL authentication), as well as it will also include authentication of clients by using certificates (Two-way SSL authentication). Fri, 04 Sep 2009 00:45:13 GMT http://www.linuxconfig.org/choosing-the-right-linux-file-system-layout-using-a-top-bottom-process As you may probably know, Linux supports various filesystems such as ext2, ext3, ext4, xfs, reiserfs, jfs among others. Few users really consider this part of a system, selecting default options of their distribution's installer. In this article, I will give some reasons for a better consideration of the file-system and of its layout. I will suggest a top-bottom process for the design of a ``smart'' layout that remains as stable as possible over time for a given computer usage. Fri, 31 Jul 2009 05:07:14 GMT http://www.linuxconfig.org/How_to_dual_boot_Windows_XP_and_Ubuntu_Linux My restless effort to promote a Linux operating system and encourage its usage among other "PC" users made me this time to tackle a core topic of this effort and that is dual boot Linux Operating System and MS Windows XP Pro. I really do not expect windows users to switch from MS Windows to the Linux from one day to another, but I rather expect a slower and gradual transition with less headaches and without productivity losses. Sun, 26 Apr 2009 10:18:38 GMT http://www.linuxconfig.org/VPN_-_Virtual_Private_Network_and_OpenVPN This article will describe a configuration of Virtual Private Network connections by using an OpenVPN application. Firstly, you will be exposed to some basic theory behind Virtual Private Networks. Then, the article will guide you with step-by-step instructions on how to setup a OpenVPN virtual private network by using algorithm Symmetric Key Encryption and cryptography Public Key Encryption. This article is meant for everybody who possesses a basic knowledge of linux administration and networking. Fri, 27 Feb 2009 00:31:00 GMT http://www.linuxconfig.org/IPwatchD_an_IP_conflict_detection_tool_for_Linux When using a GNU/Linux operating system, from time to time you may come across a situation where network connectivity was interrupted due to the IP conflict. An IP conflict event occurs when two or more hosts on the same network are configured with identical IP addresses. At the present, there appears to be no code in the Linux kernel to take care of this situation by means of appropriate Gratuitous ARP response. Very often a network administrator is left in the complete ignorance by the Linux kernel and needs to troubleshoot IP conflict the hard way. Tue, 13 Jan 2009 05:23:30 GMT http://www.linuxconfig.org/Passwordless_ssh Public key authentication allows you to login to a remote host via the SSH protocol without a password and is more secure than password-based authentication. Try creating a passwordless connection from linuxconfig.local to linuxconfig.org using public-key authentication.

Wed, 07 Jan 2009 07:40:27 GMT http://www.linuxconfig.org/Linuxgym_installation_and_user_manual Linuxgym is an online learning system, developed at the University of Technology, Sydney, Australia where it has consistently improved student pass rates by up to 40% compared with standard classroom delivery. Linuxgym's interactive exercise books provide users with real-world problems to solve, give them well-focussed hints, and analyse their code to provide helpful feedback. The "Playground" is freely available to registered users who want to try out the system. To use Linuxgym, simply install Linuxgym Live - a modification of the Ubuntu Linux distribution - which runs within 'VMware Player' a quarantined environment that leaves the host operating system safe and untouched. Once launched, it provides users with a desktop, terminal sessions and a Firefox web-browser pointing at the instructions, hints and feedback on the exercises. VMware Player is available for free and needs to be installed to run the Linuxgym Live Virtual Appliance. Wed, 07 Jan 2009 07:39:29 GMT http://www.linuxconfig.org/Recover_-_Reset_forgotten_linux_root_password This method of reseting/recovering of lost Linux root password should work on most of the linux distributions. I have tested this method for couple years already, starting with debian woody via redhat and suse to ubuntu hardy. If you run lilo boot loader instead of grub you can use the same method but with some modifications on how to edit lilo boot prompt. Wed, 07 Jan 2009 07:38:45 GMT http://www.linuxconfig.org/Filesystem_Basics This article explains basic commands for navigation within Linux file system.

Wed, 07 Jan 2009 07:30:18 GMT http://www.linuxconfig.org/Linux_Software_Raid_1_Setup This article describes step by step setup of Linux software RAID 1 on Linux Platform. Although this software RAID 1 configuration has been accomplished on Debian ( Ubuntu ) it also can guide you if you are running some other Linux distributions such as RedHat, Fedora , Suse, PCLinux0S, Sabayon etc. RAID-1 can be setup on two or more disks. This mode of RAID creates exact mirror of all data on one disk to the other disk. Wed, 07 Jan 2009 07:25:37 GMT http://www.linuxconfig.org/Partition_Encryption In this article we are going to create encrypted partition for user "linuxconfig" and use pam_mount to mount it under /home/linuxconfig directory. For this config we have used Debian Linux, however the very same principle for creating encrypted partitions can be applied also for any other Linux distributions such as SuSe, RedHat, Gentoo, Ubuntu. Wed, 07 Jan 2009 07:24:02 GMT http://www.linuxconfig.org/Linux_Cron_Guide Every user as well as administrator of the linux system very often needs to execute some programs on regular basis.
