Tutorial quote: Administering Linux and Unix-based servers does not need to be the scourge of your work day. With a handy tool called Webmin as part of your arsenal, you can regain complete control of your servers via the Web browser.
Linux Automating Builds on Linux
Post date: April 12, 2005, 19:04 Category: Miscellaneous Views: 830 Comments: 0
Tutorial quote: An automated nightly build is a process for building an application every night using an infrastructure that automatically executes the required steps at the scheduled time, without any human intervention. A well-planned build process not only builds your application, but also provides you and your team with early detection of incompatible changes in the application components and early detection of errors introduced by newly integrated code. When configured and used properly, automated builds are a critical component for ensuring that the application satisfies quality requirements and continues to run as expected.

Linux Creating Really Teensy ELF Executables for Linux
Post date: April 12, 2005, 13:04 Category: Miscellaneous Views: 738 Comments: 0
Tutorial quote: If you're a programmer who's become fed up with software bloat, then may you find herein the perfect antidote.

This document explores methods for squeezing excess bytes out of simple programs. (Of course, the more practical purpose of this document is to describe a few of the inner workings of the ELF file format and the Linux operating system. But hopefully you can also learn something about how to make really teensy ELF executables in the process.)

Please note that the information and examples given here are, for the most part, specific to ELF executables on a Linux platform running under an Intel-386 architecture. I imagine that a good bit of the information is applicable to other ELF-based Unices, but my experiences with such are too limited for me to say with certainty.

The assembly code that appears in this document is written for use with Nasm. (Besides being more appropriate for our needs, Nasm's syntax beats the hell out of AT&T syntax for anyone who learned x86 assembly language before learning to use Gas.) Nasm is freely available and extremely portable; see http://nasm.sourceforge.net/.

Please also note that if you aren't a little bit familiar with assembly code, you may find parts of this document sort of hard to follow.
Linux Today's Linux screen capture technology
Post date: April 12, 2005, 13:04 Category: Miscellaneous Views: 782 Comments: 0
Tutorial quote: "I'd like you to help me find out about video screen captures," said one of my editors a while back. "Sure, let me see what's available," I replied. He pointed me to a couple of Web sites to get me started, and here I am a few weeks later ready to share my findings. I'll discuss ways that you can make video clips in Linux, talk about their applications and shortcomings. I'll also cover suitable ways to view your masterpieces once they're recorded.

Video screen captures are useful for jobs like application training, computer instruction, or product demos. An example would be the little one-minute video I set up for my wife. She kept forgetting how to start up Mozilla Mail on her Windows 98 machine. I captured the mouse clicks and screen changes (in real time) as I ran through the process, saving it to a Macromedia Flash file. I then created a little Web page on one of my Apache servers, that described how to start Mozilla Mail and included a link to the Flash file. Instead of asking me how to do it, she can now just click on the video tutorial.
Linux Tuning up your IDE hard disks using hdparm
Post date: April 12, 2005, 13:04 Category: Optimizing Views: 1126 Comments: 0
Tutorial quote: hdparm is a tool for altering various parameters associated with IDE drives (Not SCSI). This involves things like the block prefetch, the DMA/PIO modes,
and a number of other things.

I'm writing this mini-how-to to help people get more from their system. People often complain that Linux is a bit slow for them (which it can be) I haven't seen such a post recently, but I know on TechIMO at least we always used to be talking people through using hdparm.
Linux How to play DVDs on any x86 GNU/Linux distro
Post date: April 12, 2005, 13:04 Category: Multimedia Views: 1031 Comments: 0
Tutorial quote: My folks recently bought and sent me two DVDs, but the only DVD player I have is in my Linux-based computer. Using the free software application MPlayer, I was able to watch my videos. I'll walk you through the easy steps required.
Linux Linux Web Filtering in 7 steps
Post date: April 12, 2005, 13:04 Category: Network Views: 1872 Comments: 0
Tutorial quote: How to install a transparent Squid proxy server with real-time HTTP virus scanning on Mandrake 10.0 using DansGuardian and ClamAV?

People quickly and easily access volumes of research on the Internet and correspond with a mouse click. For more and more companies, content filtering is part of the large battle to combat all kinds of online threats, including hackers, worms and viruses. Linux content filtering allows administrators to configure and manage Internet access across the entire network and to block unwanted Web content like pornography, shopping Web sites, games and gambling.

This guide contains all the necessary information for installing and understanding the architectural layout of the implementation. It was written with the assumption that you understand how to install programs and have a basic understanding of Linux Mandrake. This includes installing Linux Mandrake and RPM packages, editing files, making directories, compiling software and understanding general UNIX commands. This guide doesn’t explain how to use or configure Squid, DansGuardian and ClamAV but information on where to obtain this information can be found in the “Additional information” section.
