Showing all newswire headlines

Sometimes when I run ls to get a directory listing, I am looking for a specific file, but I want to see the whole context where the file resides. While you can pipe the output of ls to grep, that doesn't show you the whole directory with the matched files highlighted in a different color. I create a small script to do just what I want.

This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

CNN reports that "switching from a Windows-operated computer to a Linux-operated one could slash computer-generated e-waste levels by 50%." It's no longer about software freedom. It's also about environmental responsibility.

[ Indeed, green probably will be a marketing point for Linux in the future. It's one of the most important point Zonbu is using for selling their harddisk-less PC - hkwint ]

Thanks to a Filipino organisation, open source software is once again stepping in to help humanity with the release of a toolkit to assist human rights organisations in monitoring human rights violations.

In the past, I have been particularly hard on KINO and its choice of UI schemes. However, one thing I really appreciate is despite KDENLive 0.4 and 0.5/0.6 crashes and other mindless anomalies, it works.

On November 19, 2007, we sent a second letter to IBM where we insisted on implementing the stipulations contained in this petition because we believe that OS/2 is an important part of the history of the Operating System, and furthermore, it still contains values that the computer science field considers unique.

I just finished taking the latest version of Puppy Linux for a spin and was planning on doing a review. However, considering this was on my notebook, that meant connecting to the Internet, preferably via wireless.

Everex plans to introduce a competitor to Asus's Eee PC at the beginning of next year. The laptop will run the gOS, an Ubuntu-based Linux distribution, cost $400, and have a 7" screen that might even be a touch screen eventually.

This article provides guidance to DCE or DFS users who are migrating from DCE or DFS to Kerberos/NFS V4. During the transition period, these users need to be authenticated and authorized to use both DFS and NFS V4 directories. This article answers some basic questions, such as, "Can the DCE authentication server be used as a Kerberos server for NFS V4 with a Kerberos client?"

For months, I've been trying to get Microsoft to answer a few questions about the Unix technologies in its intellectual property portfolio. Microsoft agreed to an interview, then backed out. So the question remains: How much Unix code does Microsoft have its hands on?

We discovered back in September when running the Razer Barracuda AC-1 with ALSA 1.0.15 that this sound card was quite problematic with the initial CMI8788 ALSA driver. However, last month we reported that the driver was being rewritten from scratch with a much brighter outlook. We have retested the Barracuda AC-1 with its C-Media CMI8788 Oxygen APU using the latest snd-oxygen driver, which also works with other high-end sound cards such as the ASUS Xonar and Auzentech X-Meridian.

It's good news, bad news situation when it comes to Adobe's new Flash player for Linux. On the plus side, Adobe Flash Player 9 Update 3, version identifier 9.0.115.0 was made available for Linux at the same time as Mac and Windows versions. It's nice to see Linux not being treated as the little brother who only gets the older, hand-me down programs by a major software vendor. An even bigger win for Flash Player users, regardless of their operating system, is that its supports H.264.

Everex has confirmed plans to ship a UMPC (ultra-mobile PC) with a 7-inch screen, similar to competitor Asus's EEE PC. A source close to the company revealed that the device -- codenamed "Cloudbook" -- will ship with the Google Apps-oriented "gOS" Linux distribution early next year.

Nemo is the latest effort to provide a new paradigm for file managers. Its approach, at least in its first early development release, is to combine file management with calendar views. Questions remain, however, about whether the concept will scale, and whether it is an improvement on traditional file managers, or simply different.

Three cheers for the developers and management of the K Desktop Environment. They have taken a principled stand on the divisive issue of OOXML, the Microsoft Office Open XML document format. And for this the KDE folk deserve a round of applause.

Those who have experienced free software projects firsthand know that they depend on innovation and genrally foster it. And although this isn't a highly innovative era for the computer industry as a whole, free software is an exception--and likely to become more of one as it continues to come into its own. In fact, the very idea of free software is one of the most innovative ideas in the history of computing.

OpenOffice is the darling of the FOSS office suites, and it is a nice suite. It's cross-platform, and OpenOffice Writer is a first-rate word processor with a lot of advanced features. But it's not the only good option for Linux users: Abiword and KWord are excellent lightweight word processors with good feature sets, and both are licensed under the GPL. All three are wonderful. In this two-part series we're going to dig into KWord 1.6, and mine some of its hidden jewels.

Sysreport is a diagnostic utility. It collects information about the running system, which is used for Red Hat Support to analyze current problems with the system. While sysreport is generally considered non-invasive, diagnostic utilities should always be run with caution.
