Addressing New Demands on Financial Applications: Performance, Linear-Scalability, Continuous Availability on Cost-Effective Hardware
In this series of articles, you'll learn how to configure Internet-connection sharing and firewalls, and how to add useful services such as intrusion detection, HTTP caching, name services, file and print sharing, and network storage. It doesn't matter what your LAN hosts are running, whether it's Linux, Windows, Mac or something else--your Linux appliance will serve them all.

Tired of normal distro reviews, I decided to write a review in the form of a diary. Written by an intermediate Gentoo user, this review offers some insight in administering a Gentoo desktop. So bear with me while I try to make my stuff work!
In this UpFront podcast, Red Hat Chairman, president and CEO Matthew Szulik talks with eWeek Editorial Director Eric Lundquist about Red Hat's purchase of JBoss, the future of open source and Szulik's interest in reviving the U.S. education system.
- After many months of working and planning towards this day, I'm pleased to announce the official public release of the Gnu-HALO alpha 0.1 Linux Live CD... The Gnu-HALO Project is an experiment with some new, some old, and some used UI and system design concepts from throughout the history of computing. The four key elements are as follows: 1. The HALO Desktop and System User Interface, 2. The HALO System Architecture and File Layout, 3. Size and Modularity Design for Low-End Systems, 4. The HALO Out-of-Box End-User Experience.

Organizing disparate pieces of data on the hard disk and from the Web is a tricky proposition. For example, as I am learning Japanese, I have hundreds of text notes, images, loose Web pages, scanned articles, and other small pieces of data, which I refer to as "stuff." Desktop search applications can locate files and find text in them, but they cannot organize anything. Putting things into separate folders doesn't really solve the problem. Fortunately, two utilities, ScrapBook and BasKet, help me collect and organize "stuff" in a structured fashion.
Microsoft's corporate vice president of Windows Live and MSN marketing, Martin Taylor, occupied the chair for just three months before he was unceremoniously "disappeared." This is bad news for Windows Live competitors, who have been thoroughly enjoying pratfalls similar to those made by Taylor in his previous assignment: Microsoft's silly anti-Linux crusade, "Get the Facts."

Atomicity is a property of an operation either to succeed or fail completely. Disks assure atomicity at the sector level. This means that a write to a sector either goes through completely or not at all. But when an operation spans over multiple sectors of the disk, a higher-level mechanism is needed. This mechanism should ensure that modifications to the entire set of sectors are handled atomically. Failure to do so leads to inconsistencies. This document talks about the implementation of the Journaling Block Device in Linux.
Silver anniversaries are normally joyous occasions, but not this one. June 5, 2005 marked the 25th anniversary of the discovery of AIDS. Amid the calls for greater awareness and increased funding was recognition that, from a medical viewpoint, billions of dollars spent on research had produced little progress in recent years. Find out how Linux is part of the fight to cure this disease once and for all.
Greg KH posted an updated patchset for removing devfs from the mainline Linux kernel as was already done in the -mm kernel, "they are the same 'delete devfs' patches that I submitted for 2.6.12 and 2.6.13 and 2.6.14 and 2.6.15 and 2.6.16. It rips out all of devfs from the kernel and ends up saving a lot of space." The idea of removing the unmaintained devfs whose functionality has been replaced by udev has been discussed since late 2003 [story], gaining momentum in 2005 [story] and leading to lengthy debates [story]. In his latest email Greg went on to explain, "since 2.6.13 came out, I have seen no complaints about the fact that devfs was not able to be enabled anymore, and in fact, a lot of different subsystems have already been deleting devfs support for a while now, with apparently no complaints (due to the lack of users.)" Greg continues to make the case for removing devfs:
"This patchset has also been in the -mm tree, with no complaints or issues for the past few months. It's also been almost a full year past the date when we said we would delete devfs from the kernel tree in the file, Documentation/feature-removal-schedule.txt, almost two years since we publicly announced to the world that devfs would be removed from the kernel tree. So I think people have had plenty of advance notice that this was going to happen by now :)"
INDIANAPOLIS, IN -- (MARKET WIRE) -- 06/21/2006 -- ANGEL® Learning, recognized innovator of enterprise e-learning software and services, today announced it is contributing substantial intellectual property to the IMS Global Learning Consortium.

A blogger's claim that one rogue operator tricked Google into indexing over 5 billion bogus pages serving Pay-Per-Click ads has helped solidify the claims of the legal teams chasing the search giants: PPC advertisers may, in fact, be getting screwed through faked clickery. At the same time, it helps explain the increasing irrelevance of search results. This, for many, is a deal killer. Searchers and advertisers alike need a better model
. But who can deliver it?
Plugging a new PC into your network, going out for a healthy walk, and returning to a completed operating system installation is one of life's little pleasures. Remember, laziness is a virtue in network administration. Hamsters spend their lives running the same circles. Network administrators automate repetitive tasks.
What exactly is the Internet? This article will explain the concepts required to understand BGP, our next Networking 101 topic. Shipping packets around the Internet requires the cooperation of separate organizations, so it isn't as straightforward as learning about an IGP routing mechanism.
Ubuntu has become the most popular Linux distribution for new Linux users. It's easy to install, easy to use, and usually "just works." But moving to a different operating system can be confusing, no matter how well-designed it is. Here's a list of tips that might save you some time while you're getting used to Ubuntu.
This list is compiled from a variety of sources and is intended for anyone who wishes to find centralized reading material about Eclipse. One of the biggest challenges new Eclipse users face is where to find the right information for a task. This article provides a small step in solving that problem.
In an earlier article, I covered the basics of making outlines in Emacs, but there's a lot more that you can do with them. In this article I'll show how to export and print outlines, customize outline heading line colors, and use outline mode's special features in everyday documents -- such as numbered lists, traditional outlines with Roman numerals, and even book manuscripts containing chapter and section headings.
