Back Up (And Restore) LVM Partitions With LVM Snapshots

This tutorial shows how you can create backups of LVM partitions with an LVM feature called LVM snapshots. An LVM snapshot is an exact copy of an LVM partition that has all the data from the LVM volume from the time the snapshot was created. The big advantage of LVM snapshots is that you do not have to worry about open files and database connections, and you do not have to interrupt/halt services on the live partition because a snapshot is usually created in fractions of a second, so your users will not notice any disruption, and your snapshot holds consistent data. http://www.howtoforge.com/linux_lvm_snapshots

Using Sharp Fonts On A GNOME Desktop

You might have noticed that fonts are quite fuzzy on Linux desktops which can make your eyes ache if you have to sit in front of your computer all day long. Font rendering is still a little bit awkward and one of the last weaknesses of Linux desktops. This tutorial shows how you can make GNOME and all GNOME applications (such as Evolution, the file browser Nautilus, etc.) use sharp fonts. In fact, we will use the Microsoft Windows standard font, Tahoma, as the standard font in GNOME, too, which will make the desktop look quite familiar if you are used to working with a Windows desktop. http://www.howtoforge.com/sharp_fonts_gnome

This tutorial shows how you can install and configure Beryl on an Ubuntu 7.04 (Feisty Fawn) desktop with an ATI Radeon graphic card. With Beryl, you can make your desktop use beautiful 3D effects. We will use the open-source ATI driver that comes with Ubuntu plus AIGLX to achieve this; the other way to do this would be to use the closed-source ATI driver together with XGL which seems to be a bit unstable. http://www.howtoforge.com/ubuntu_feisty_beryl_ati_radeon

How To Harden PHP5 With Suhosin (Debian Etch/Ubuntu)

This tutorial shows how to harden PHP5 with Suhosin on Debian Etch and Ubuntu servers. Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections. http://www.howtoforge.com/suhosin_php_debian_etch_ubuntu

Displaying "MyComputer", "Trash", "Network Servers" Icons On A GNOME Desktop

Having these icons on the desktop is useful if you switch from a Windows desktop to a GNOME desktop and are used to having them on the desktop. http://www.howtoforge.com/display_my_computer_and_trash_icons_on_gnome_desktop

Building DVD Images Of Debian/Ubuntu Repositories

This article offers a simple way of creating DVD images of Debian or Ubuntu http/ftp repositories. Ubuntu does not offer DVDs ready to download with its main, universe, multiverse and/or restricted repositories. With the contents of this guide you can do it yourself. Having the Ubuntu or Debian repositories on DVD can be useful for those users who do not have access to the internet where they have their Ubuntu installed but have access somewhere else to download the repository and build and burn the DVDs. http://www.howtoforge.com/dvd_images_of_ubuntu_repositories

Speed Up Google Analytics

This method uses crontab to execute a shell script that downloads an updated urchin.js file every 24 hours and saves it into your local sites directory so that it can be served by your web server instead of the google-analytics.com web server. The problem with google-analytics.com is that when google-analytics.com/urchin.js is requested by billions of web users all over the world at one time, it can cause your pages to load very slowly, especially if you are using WordPress or a similar CMS. http://www.howtoforge.com/speed_up_google_analytics
