Unix+clones How to create OpenOffice.org macros and automation
Post date: April 12, 2005, 19:04 Category: Software Views: 624 Comments: 0
Tutorial quote: There are times when you need to perform some task over and over, or when a task is complex enough that doing it manually makes it hard to get it right. OpenOffice.org macros allow you to save a sequence of operations with a single name so you can do the same thing repeatedly. Automation is a first cousin to macros. It lets another application control OOo and make things happen without user intervention.
Unix+clones File Transfer Protocol
Post date: April 12, 2005, 13:04 Category: Network Views: 781 Comments: 0
Tutorial quote: Wake up, you goodness-to-GUI slacksters! It's time to get up and get out of that hammock and put your feet on the ground and your hands on the CLI. This week we're going to talk about data in motion. Taking a file from one place on the network. Putting it someplace else. Most often today some form of FTP, the File Transfer Protocol, is used to do those things. It's been part of the Internet since there was an Internet.
Unix+clones OpenSSH/Keychain Howto
Post date: April 12, 2005, 12:04 Category: Network Views: 1009 Comments: 0
Tutorial quote: This howto will show you the fundamental ways to use OpenSSH; how to generate public/private key pairs and strong passphrases, and how to use the wonderful Keychain utility to automate your SSH logins. This is exceptionally handy when you log in and out frequently, and don't want to keep entering your passphrase.
Unix+clones How to Set Up a Jabber Server
Post date: April 12, 2005, 11:04 Category: Software Views: 3036 Comments: 0
Tutorial quote: Unless you have been living under a rock for the past few years, you must have heard about instant messaging and how it has changed the world of communications over the Internet. According to http://www.webopedia.com, Instant Messaging (IM) is a service that alerts users when their friends or colleagues are on line and allows them to communicate in real time through private online chat areas. Two of the most popular IM services are AOL Instant Messenger (AIM) and MSN Messenger. Unfortunately, most of the publicly available servers use proprietary protocols that only allow you to communicate with users on the same system. These systems are not compatible with each other and can't be accessed from other clients.

Jabber is an open source implementation of the IM server that aims to change this. It uses streaming XML protocols that are free, open, and public. These protocols have been formalized by the Internet Engineering Task Force (IETF) as the approved instant messaging and presence technology under the name of XMPP. The first Jabber technologies were developed in 1998 by Jeremie Miller and is now used on thousands of servers world-wide to enable millions of users to communicate with each other.

The biggest advantage of the Jabber server when compared with commercial IM servers is that, since it is open source, anyone can run a Jabber server and it can be restricted to a specific community like a company work force or a group of friends. In this article, I will document the steps I took to set up a Jabber server and how I managed to overcome the difficulties I faced. Hopefully this will make it easier for you to set up your own Jabber server.
Unix+clones Comparing MySQL performance
Post date: April 12, 2005, 02:04 Category: Benchmarks Views: 1244 Comments: 0
Tutorial quote: With the introduction of the 2.6 Linux kernel, FreeBSD-5-STABLE, Solaris 10, and now NetBSD 2.0, you might be wondering which of them offers superior database performance. In my previous article, I discussed the tools I chose to test these venerable operating systems and the methodology by which they were tested. The result is this MySQL performance comparison between OpenBSD 3.6; NetBSD 2.0; FreeBSD 5.3 and 4.10; Solaris Express (build 69); and Linux 2.4 and 2.6 (Gentoo-based). Read on for the results.
Unix+clones Using MySQL to benchmark OS performance
Post date: April 12, 2005, 02:04 Category: Benchmarks Views: 1460 Comments: 0
Tutorial quote: It seems to be an exciting time for *nix operating systems, with a number of them recently releasing new versions that bring the addition of expanded features and claims of improved performance. If you're using GNU/Linux, OpenBSD, NetBSD, FreeBSD, or Solaris as a database server, you've probably recently considered an upgrade or switch to another OS in that list due to marketing hype and hearsay. This article will show you how to benchmark operating system performance using MySQL on these OSes so you can find out for yourself if you're missing out. While this may not necessarily be indicative of overall system performance or overall database application performance, it will tell you specifically how well MySQL performs on your platform.

The following operating systems were used for the comparison testing:
- FreeBSD 4.11
- FreeBSD 5.3
- NetBSD 2.0
- Linux 2.6
- Linux 2.4
- Solaris 10 x86 (build 69)
- OpenBSD 3.6
