It wasn't entirely clear from an 'apt-get source boot-floppies' how to make a custom CD image. I just wanted to make a netinst CD with a kernel that had some new driver that I needed so I could get Debian on the box.
There is a nice screenshot tour with 93 screenshots of the new PCLinuxOS 0.92 at HowtoForge.
I work as a consultant in a Windows-centric work-place and we remotely administer Windows servers. We trouble-shoot Windows clients. We keep spammers out of our Exchange servers. We defrag. We update. We install antivirus programs. We eliminate spyware. I suppose it would be fair to say that Microsoft keeps us in business. One day, while the boss was away, I shoved a spare hard-drive into my computer and installed Ubuntu 5.04. I managed to work for a month and a half before the Boss noticed I was using Linux - and that was only because he happened to glance at my screen. Half a year later, I am still using Ubuntu (now version 5.10) at work and I am more productive than ever.
The site is down because they are under a DOS attack. I can think of several possible ramifications, but I thought you might want to know.
The number of open source deployments by governments across the world has accelerated over the last few years. To date at least 160 international local and national governments have deployed open source software and over $2bn has been spent on the Linux open source operating system, according to figures from Linux vendor Red Hat.

Many American conservatives recoil when people bring up the issue of persecution. They call it un-American. We quote the US Constitution when it serves our interests. But when someone is in the minority, reminding the majority of our rights under the constitution means encountering verbal abuse.
So as unpopular as the following argument may seem, let me remind you that a democracy that guarantees citizens certain rights and privileges forms the foundation of our system of government. Vocal incriminations will not change that.
Now, let's take a closer look at some core issues of ethics. Diggable
Buying Web hosting for your business is an important decision. Trying to choose a hosting company can be confusing, especially when you're reading the companies' advertisements. But understanding Linux hosting ads can be easy, once you know how.
For the past four years, I have been the Chief Software Architect for OpenLab international, the company that created the OpenLab GNU/Linux distribution. Over that period, Lazarus has long been included in the distribution, but what fewer people realize is how critical it is to the actual distribution development. Read on for some insight into how we use it."
With a few notable exceptions, such as the Massachusetts directive in favor of OpenDocument, government agencies usually do not experiment or promote technological innovation in their own offices. However, a small and scattered group of public employees in Italy is trying to join forces to reverse this flow.
Today, ODF became just a political football on Beacon Hill, as Massachusetts politicians jostled to take control of IT policy in the Commonwealth.
The Apache HTTP Server is the most popular web server due to its functionality, stability, and maturity. However, this does not make it suitable for all uses: slow machines and embedded systems may have serious problems running it because of its size. Here is where lightweight HTTP servers come into play, as their low-memory footprints deliver decent results without having to swap data back to disk.
Similarly, these small HTTP servers are suitable to serve static content efficiently so as to allow Apache, mod_perl, mod_python, or even servlet containers to handle dynamic requests without tying up memory-hungry children to serve small images. In other words, these applications can serve as a complement to your existing full-featured web server, not as a replacement.
It is hard to believe that 19 shiny flat screen computers can cure the ills of this tiny community in South Africa's arid north where people battle every day against poverty, AIDS, illiteracy and hunger. Yet U.S. computer giant Hewlett-Packard Co. and South African President Thabo Mbeki are promoting Dipichi's smart new IT lab as a blueprint for how technology can trigger growth and tackle poverty across the world's poorest continent.
The importance of Linux in the world of supercomputers is difficult to understate. Linux is the installed operating system on 72 percent of the supercomputers listed in the latest Top 500 (www.top500.org) tally of the world's fastest supercomputers...The LS/X is the new high end system that Linux Networx claims can provide, "sustained application performance for configurations up to 100 Teraflops."
If you use charts to represent relationships between data or objects in presentations or project reports, try Graphviz. Licensed under the Common Public License Version 1.0, Graphviz is visualization software, designed to help you easily create structural information. You can use it to visually represent database and table relations in a project report or a simple Web site hierarchy.
An anti-spyware initiative backed by Internet portals Yahoo and AOL would certify downloadable software as consumer-friendly and non-invasive.
Training specialist Advanced Training has partnered with open source solutions company Cybersource to offer a training solution for businesses looking to migrate users off Microsoft Office onto OpenOffice.org.
Call it the revenge of the nerds -- digital style. For years, computer geeks and cyberlibertarians have howled about aggressive user restrictions programmed into music CDs, movie DVDs, and all kinds of software...Now the tide might be turning, thanks to a classic case of overreaching that has fomented a backlash against the industry.
[Ed.- Overreaching, my aunt Fanny. Sony simply got caught. How many more are there? -tuxchick]
- What if your desktop were actually a 3D environment? What if your CD or movie database becomes a 3D jukebox? Project Looking Glass is based on Java technology and explores bringing a richer user experience to the desktop and applications via 3D windowing and visualization capabilities. Interested?
OSDir has some nice shots of Project Looking Glass.
A huge number of the questions on #apache have to do with mod_rewrite. And, fairly frequently, I find myself thinking that the problem being discussed would be so much easier to solve if we could just write a Perl script to deal with it. Of course, you can, using the RewriteMap, but it's moderately hard to come by good examples of using this, either in the documentation, or elsewhere online.
