Memory leaks and code exploits are a fact of life for both browser developers and their users — regardless of the specific browser in question. For the developers at Mozilla, both issues have been on their minds this week, as browser bugs of both sorts have been all over the news. Security researchers published code on Wednesday that reportedly would allow an attacker to load unauthorized software on a target's computer simply by having the target view a specially-coded XML file. According to reports, Mozilla developers were blindsided by the bug and immediately raced to find a patch.

Red Hat Inc. posted a lower quarterly profit on Wednesday, but the results surpassed most estimates as sales grew sharply and the software company moved aggressively to rein in costs. In after-hours trading, shares of Red Hat, a provider of open-source software used by businesses, rose more than 4% to $15.72 following the report.

It was a short presentation that focused dryly on "opportunities" for open source in something he called the "service-driven data center." But when he turned to the need for Linux to inter-operate with Windows in this service-driven data center, Novell's chief executive Ron Hovsepian delivered an apology - of sorts - for his company's controversial marriage to Microsoft in 2006. Speaking at the Open Source Business Conference (OSBC), Hovsepian said he could have done a "better job" of communicating about the deal and suggested he got caught up in thinking about customers, instead of the perception and possible fallout from dealing with Microsoft.

With the publication of drive by download attack code this week which impacts Firefox security on all platforms by exploiting an unpatched and critical flaw in the browser, and the successful hacking of the Firefox client (as well as IE8 and Safari) at the CanSecWest PWN2OWN competition, you might be getting a little concerned that the ‘more secure than Internet Explorer’ choice isn’t, perhaps, so secure after all.

This tutorial shows how to prepare a CentOS 5.2 server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

In this article, we have learnt how to secure a Scalix server. Firewalls and OpenVPN do a very good job, but there are some quirks where the admin has to pay attention. Stunnel works flawlessly, whereas https redirection does not survive updates and cannot be recommended, but it helps understanding the structure of the Scalix web server.

In this article we will cover the installation and configuration of the FreeNAS server. We boot the FreeNAS server from the LiveCD disk and configure a simple disk that is accessed by CIFS and http://FTP. We also look at how to install FreeNAS to the hard drive and how to upgrade it.

You don’t have to be an uber system administrator of a network to use Htop. It might have been designed with the masters of the universe in mind but just because you are a mere solitary desktop user in a Pizza-strewn study room staring at a single machine doesn’t mean you can’t get it and use it too. This article will show you how to configure and use htop to monitor system resources and how to use this dinky interactive application to manage running applications and processes on your desktop.

More than two years ago the South African Revenue Service (SARS) began a process to migrate its desktops to Linux by calling for a proof on concept. Two years on the desktop migration has not happened but the tax-collection arm of government has made some progress towards wider open source use, including wide use of Suse Linux. We take a look at exactly what has been going on.

While backup and recovery solutions are considered paramount in most organisations, they are possibly one of the most overlooked procedures in company security policies, mainly because they seem to try to achieve the opposite. Security demands strong encryption and overall policy control over employee and enterprise-wide information, while backup software tries to simplify the data centre recovery process regardless of platform, location and user, anywhere on the network.

Red Hat CEO doesn't know how to make money off of Desktop Linux.

Each time you upgrade to a new version of Ubuntu, here are five essential Ubuntu modifications you should consider making, according to WorksWithU, the independent guide to Ubuntu.

There’s been alot of discussion about IBM being in talks with Sun Microsystems about a $6.1 billion acquisition. Initially Sun’s stock (ticker: JAVA) shot up significantly while IBM’s stock (ticker: IBM) initially dropped a few points before recovering to only a small loss. While this may or may not be good for each company, I started to wonder what would happen to some of the projects that Sun manages, specifically MySQL but also ZFS, OpenSolaris and others.

There are lots of Linux distros being touted as great desktop operating systems for PCs. However, there's only one that I can wholeheartedly recommend to business owners as a Windows replacement: Novell's SUSE Linux Enterprise Desktop 11 (SLED). SLED 11, which was released on March 24, stands above its competitors because it works and plays well with existing Windows business networks, data files and application servers. You can, of course, add this functionality to other Linux distributions -- if you're willing to do it manually. SLED gives you pretty much the full deal out of the box.

Imagine owning a smart phone that you can hack just as freely as a PC. OpenMoko is an embedded Linux-based mobile platform, and the Neo Freerunner is OpenMoko's slick little touch-screen smart phone that runs OpenMoko. Unlike other mobile platforms that are open in buzzword only, OpenMoko is a genuinely open hardware and software platform. Carla Schroder investigates this radical new approach to mobile devices.

Just two days before Microsoft and Novell signed a controversial deal in 2006, the two sides still hadn't figured out a way to make peace over Linux without violating the licensing terms that govern the open-source operating system. The terms of the GNU General Public License made it tough for Microsoft to get paid a royalty for each copy of Linux that Novell sold and also made it tough for Microsoft to offer patent protection to Novell without giving it to all users of Linux. But, just hours before it hoped to announce a deal, Microsoft workers thought up an end-run around the provision. Instead of protecting Novell, Microsoft hit on the idea of offering legal protection to Novell's customers.

Nothing boosts my productivity more than good music. That's why I always keep Last.fm radio running when I'm working. Or rather, used to keep it running: Last.fm has announced that the company starts charging international users for streaming music. It's not a big deal, except that the service will remain free in the US, UK, and Germany. For me it's as insulting as Windows-only applications. It's not the end of the world, though: as always, the VLC comes to the rescue.

Back when I worked in the Network Operations department at one of my previous jobs, we used to chuckle when a customer would call us reporting that “the Internet is down.” Now, I realize that there are otherwise intelligent computer users out there who don't understand why that might cause a technician to chuckle, and I'm not trying to make fun of them. But you've got to know that help desks get this type of trouble report more frequently than they should. I've known quite a few hardware technicians or software developers who were very good at what they did, but who didn't have the first clue as to how to diagnose a network problem. To them, the Internet, and networking in general, was just “Pure Freaking Magic”. Actually, it is magic, but it's not a magic that we can't learn to troubleshoot. So, let's begin.

Yow to create symbolic links from the command line. Making shortcuts to the files you use most can make your life easier.

Learn to scale your UNIX® Python applications to multiple cores by using the multiprocessing module which is built into Python 2.6. Multiprocessing mimics parts of the threading API in Python to give the developer a high level of control over flocks of processes, but also incorporates many additional features unique to processes.
