Downloading without a Browser

Post date: November 29, 2005, 19:11 Category: Software Views: 3546 Comments
Tutorial quote: Ever had to download a file so huge over a link so slow that you'd need to keep the web browser open for hours or days? What if you had 40 files linked from a single web page, all of which you needed -- will you tediously click on each one? What if the browser crashes before it can finish? GNU/Linux comes equipped with a handy set of tools for downloading in the background, independent of the browser. This allows you to log out, resume interrupted downloads, and even schedule them to occur during off-peak Net usage hours.

Fight Image Spam With FuzzyOCR And SpamAssassin On Debian Lenny

Post date: April 29, 2010, 14:04 Category: Installing Views: 3324 Comments
Tutorial quote: This tutorial describes how to scan emails for image spam with FuzzyOCR on a Debian Lenny server. FuzzyOCR is a plugin for SpamAssassin which is aimed at unsolicited bulk mail containing images as the main content carrier. Using different methods, it analyzes the content and properties of images to distinguish between normal mails (ham) and spam mails. FuzzyOCR tries to keep the system load low by scanning only mails that have not already been categorized as spam by SpamAssassin, thus avoiding unnecessary work.

Optimizing Desktop Performance, Part II

Post date: May 24, 2005, 18:05 Category: Optimizing Views: 4032 Comments
Tutorial quote: As we discussed in last week's article, for most of its existence, people have distributed Linux as a workstation or a server rather than as a desktop. The default workstation that evolved has existed mostly for use by developers. So, when you install a Linux distribution with a graphical interface, it generally looks like what a developer might want. In addition, it performs similar to how many UNIX workstations work, which can seem slow.

In this article, we continue to look at the Linux desktop in a different light. Here, we think of it as a computer system with a fast interface that we can optimize for the knowledge worker and consumer.

Xen: How to Convert An Image-Based Guest To An LVM-Based Guest

Post date: April 19, 2009, 10:04 Category: Miscellaneous Views: 3812 Comments
Tutorial quote: This short article explains how you can move/convert a Xen guest that uses disk images to LVM volumes. Virtual machines that use disk images are very slow and heavy on disk IO, therefore it is often better to use LVM. Also, LVM-based guests are easier to back up (using LVM snapshots).

Setting up yum on SUSE LINUX 10.0

Post date: October 16, 2005, 16:10 Category: System Views: 6114 Comments
Tutorial quote: Why should I use yum and not yast? Well, yast is nice, but has some disadvantages: It can#t check for gpg keys, you have to trust the mirrors you add. And, speaking about mirrors, yast has no real mirror management for one source. Especially in these times the most and best known SUSE mirrors are very slow or just closed down, so you have to add other sources in yast. But yast needs your clicks when a mirror is not reachable, and if you enter several sources just as mirrors, it checks every single source - that takes quite a long time!
A last reason (which is not important know because SUSE LINUX has a ugly workaround) is that yast is not able to handle packages for different architectures - it can only install packages for one architecture.

Xen from Backports on Debian Sarge

Post date: August 12, 2006, 18:08 Category: Software Views: 3276 Comments
Tutorial quote: There is a great howto about installing Xen on Debian Unstable. It is really easy to do and it runs fine. Nevertheless, on production servers, that's not an optimal solution. Debian Unstable has too many updates and things change too often. On production machines, a Xen host system should be stable, secure and should not need much attention. That is where Sarge comes in. If you pull the Xen packages from backports and install them on Debian stable you've got the best of both worlds. Let's do so!

How To Set Up Database Replication In MySQL On Ubuntu 9.10

Post date: January 12, 2010, 12:01 Category: Miscellaneous Views: 3450 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.
