The Linuxer

Voiceroute, a software PBX vendor, originally started as a proprietary software company but went (at least partly) open source earlier this year. In this video, CEO Ming Guang Yong says the company should have moved toward open source "a lot sooner," and explains why. He and CTO Navin Kumar also talk about some of the specific differences between their open source and proprietary versions, including how and where they draw the line between the two, and share their thoughts about dealing with open source developers and building a successful open source development community.

One of the goals of the Software Freedom Law Center (SFLC) is to become a center for education in free and open source software (FOSS) legal issues. As part of this effort, the SFLC has already published "A Legal Issues Primer for Open Source and Free Software Projects." Its latest effort in public education, released last week, is "A Practical Guide to GPL Compliance," a 15-page guide for FOSS projects on how to avoid violations of the GNU General Public License (GPL) and Lesser General Public License (LGPL). The guide is a practical summary of its subject, but its wording is unnecessarily legalistic, and its structure and omissions sometimes fall short of the goal of being a standalone reference.

No one saw this coming. Cisco, the networking giant, announced today it was buying PostPath, maker of the Linux-based Exchange server replacement PostPath Server.

Suppose someone wants to send you a large file. They could try to send it via email, but many email servers impose limits on file size. They could try sending it over during an instant messenger or Internet Relay Chat session, but that's slow, as the file actually gets transferred twice: once to the chat server, then to your machine. File transfer services like RapidShare and MegaUpload are fine, but not for confidential information. Of course, you could set up an FTP server on your box, but you don't want to leave that door open all the time. Luckily, there's now an easy solution: droopy.

For enterprise system administrators looking for interoperability with Microsoft Exchange, but not the high costs associated with it, PostPath email and collaboration server could be a smart business investment. Boasting interoperability with Exchange environments for a third of the cost, thanks to its use of the Postfix mail server and many other open source components, PostPath provides drop-in capability and compatibility with Exchange environments without the need for making changes to Outlook on the client side. Being compatible with Exchange means that it can be managed using Microsoft's Active Directory infrastructure. The latest version, PostPath v3.1.2, adds support for Blackberry Enterprise Server and ActiveSync, allowing you to use mobile devices to access your email.

ReadyTechs provides network support services for companies that don't want the expense of hiring and caring for their own employees. Now CEO Gerry Libertelli says the company is using Linux virtualization to open a new income stream based on cloud computing.

If you follow technology trends, you have probably heard of the semantic desktop -- a data layer for annotating and sharing the information in your computer. But what you may not be aware of is that the semantic desktop is not a distant goal, but scheduled to arrive at the end of 2008. And, when it does, the idea will probably be implemented through the work done by the Nepomuk project, and, most likely, by KDE first.

If like first-person shooters, you'll love Sauerbraten. This open source game might not have the visual finesse of other FPSes, but what it lacks in the graphics department, Sauerbraten more than makes up for with its various single and multiplayer modes, including an experimental role-playing game mode, and a unique WYSIWYG in-game map editor. Sauerbraten blends the best of FPSes like Quake and Max Payne to give you a unique gaming experience.

If your desktop hardware includes a graphics processing unit (GPU), you can do some cool image processing with the CVL suite of tools, which includes in image viewer, an image tone mapper, and a command-line tool for non-interactive image processing.

SUSE has been around almost since the dawn of consumer-level desktop Linux, and openSUSE 11 upholds the SUSE reputation for having not just a wide range of available applications, but also excellent documentation and a fine user-to-user support community. For this video we chose the KDE 4.x desktop option. KDE 3.5x and GNOME are also available as defaults in openSUSE.
