Linux Open Source

1. Building a Linux Network Appliance
   You probably already know that a firewall is an essential component in your network border security. But you may not know that a Linux-based iptables firewall is especially robust and configurable. Today we'll set up system administration using Webmin, and in our next installment we'll create a good stout Internet-connection sharing firewall. It's important to keep in mind that a firewall is only a single piece of your security architecture. It's equally important to pay attention to your application-level and operating system security. Linux/Unix hosts can be locked down to the point that a firewall is not necessary. But Windows cannot, and Mac OS X is still an unknown.
     
2. Linux/Open Source
   Genuitec will link rival NetBeans with its Eclipse open source technologies in a preview release of the MyEclipse 5.0 environment for enterprise and Web application development .Built on top of the Eclipse software development kit, the preview version is dubbed a Milestone 2 release. It will have most of the new functionality to be featured in the general release of MyEclipse 5.0, due in August. MyEclipse 5.0 offers users multiple ways t o build Web applications, with support for technologies such as AJAX (Asynchronous JavaScript and XML), JavaServer Pages, and Struts.
      
3. Portable Linux DAW Records, Mixes
   Startup Trinity Audio Group is using Linux and open-source audio applications in a small, portable, inexpensive DAW (digital audio workstation) claimed capable of professional-quality recording and mixing. The Trinity DAW is based on an Intel PXA270 processor, and targets field recordists, podcasters and producers. The Trinity DAW uses lots of neat embedded and open-source technologies, including an off-the-shelf CPU module, a 1.8-inch hard drive, VGA touchscreen LCD, and the open-source Audacity DAW software. 
     
4. What is Linux
   Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Developed under the GNU General Public License , the source code for Linux is freely available to everyone. Click on the link below to find out more about the operating system that is causing a revolution in the world of computers. Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone.
      
5. Open Source and Linux News & Software
   A while ago I blogged (lost in migration, reposted) about my complete disappointment in the currently available programs for screen capture in Linux. As a result of that post, I was contacted by Christian Linhart who produces a program called ?DemoRecorder?.While the world awaits the final release of Microsoft's long overdue IE7, the Mozilla Foundation is set to release its own beta Firefox 2.0 and, from all reports, it's a very nice piece of work. A brief demonstration of a preview of release candidate of the beta illustrates that, unlike IE6 users, Firefox users will not have to get used to a new interface; they'll just get some extra functionality.
   
   
6. The Linux/Open Source Software
   Microsoft is not a name normally associated with the open source community, much less the community?s signature gathering, but attendees at the 2005 Linux World Conference & Expo today heard Bill Hilf, open source industry veteran and former IBM Linux deployment specialist, talk about his experience running Microsoft?s Linux/OSS Lab. While Microsoft?s presence at the conference may raise some eyebrows in the open source community - the last Microsoft executive to speak at the event jokingly wore a flack jacket - Hilf?s focus is on building bridges. Today, he led a session at the conference titled ?Managing Linux in a Mixed Environment .
      
7. Open Source SGI and Linux
   Linux® software for SGI® systems is designed to ensure compliance with industry standards while providing scalability and high performance:

   * SGI Advanced Linux? Environment* - contains patches for hardware support, scalability and performance, as well as various fixes identified both within the Linux community and within SGI.
     
8. About Linux
   Find below the basics of Linux and Open Source. Alternatively, go to the Linux in Australia page for information about Linux in Australia, case studies, screenshots of Linux, papers and more. Linux is a UNIX-like operating system originally created by Linus Torvalds as a student in 1991, and now developed by a team of programmers around the world. Linus also introduced the cute icon of the penguin as the Linux mascot. The story is 100% Australian It has gained a huge amount of interest because it is a secure, reliable, high-quality and low-cost alternative to other systems, and is freely available to research, modify and redistribute under the terms of the GNU General Public License 
   However, Linux is not a complete operating environment by itself - it is just the 'kernel', a crucial piece of software that allows applications and hardware to communicate and work together. Much of the value of Linux comes from "Open Source" and "Free Software" programs.

11. Open Source Tripwire and Tripwire Enterprise
    If you need to detect changes made to your Linux and UNIX servers, you have three choices - Open Source Tripwire, Tripwire for Servers and Tripwire Enterprise. Although they all share a common heritage, these solutions have significant differences that make them appropriate for different IT environments:
    1.Open Source Tripwire is suitable for monitoring a small number of servers where centralized control and reporting is not needed and professional support is not a requirement.
    2.Tripwire for Servers is the solution for IT organizations requiring only server monitoring, with detailed reporting and optional centralized sever management across Linux/UNIX/Windows platforms.
    3. Tripwire Enterprise is the best choice for IT organizations needing to securely audit changes across Linux/UNIX/Windows servers, databases, network devices, desktops, and directory servers.
      

12. Linux open-source and control
    Over at Slashdot, they're debating a statement by Greg Mancusi-Ungaro, Novell's Linux and open-source software marketing manager, in a recent Linux Format interview, that "Well, if we ever woke up one day and said 'Wow, Novell is the Microsoft of Linux' or 'Red Hat is the Microsoft of Linux', then the Linux movement would be over. companies and individuals want to control open-source software. Even now, many people have real trouble with the idea that you can make a very successful software business and not own a single line of its code. This is why I always smile at the idea that Microsoft will someday try to destroy Linux by releasing its own MS-Linux. The current generation of Microsoft leadership will never make that move. 
        

13. OpenMosix,an Open Source Linux
    This is the openMosix Project. openMosix' Project Leader and Founder is Moshe Bar. This page contains only the most current highlights, but it provides links to the entire project.openMosix is a Linux kernel extension for single-system image clustering. This kernel extension turns a network of ordinary computers into a supercomputer for Linux applications. Once you have installed openMosix, the nodes in the cluster start talking to one another and the cluster adapts itself to the workload. Processes originating from any one node, if that node is too busy compared to others, can migrate to any other node. openMosix continuously attempts to optimize the resource allocation. 
       

14. Sun's Linux Offerings
    Sun brings a comprehensive systems approach to Linux-based operating systems. Sun provides Java technology, x64-based servers and workstations, Red Hat Enterprise Linux, and SuSE Linux Enterprise Server along with Sun's Java Enterprise System and suites-all supported by Sun services.
    * Linux and Solaris?A common heritage: Coming from the same roots, Solaris and Linux are complementary and a natural fit to work together. Now with Solaris Containers for Linux Applications you can run Linux applications unmodified on Solaris.
    * The Linux community: Sun is one of the largest contributors to the GNU/Linux operating system. It has made substantial contributions to such key areas as Mozilla, GNOME and X.ORG as well as turning StarOffice over to the community in the form of OpenOffice.org.
    * Sun's Open Source commitment: Sun has opened more lines of source code than any other company and continues to be widely involved with many open source communities. And now, with OpenSolaris, the most advanced operating system on the planet is available as open source. 
       

15. Linux, open source power call center for Katrina
    As Hurricane Rita bears down on the Gulf Coast, there is at least one fear that can be put aside. If families get separated, they can quickly locate each other from any phone by calling Contact Loved Ones, a free service powered by an open source Asterisk PBX system and MySQL database running on Debian Linux. Moved by the stories of families separated by Hurricane Katrina, Web development experts Dan Schoeffler and Yaakov Menken set up Contact Loved Ones (CLO) in a matter of days. Information about CLO and how to use it is now available in Red Cross centers throughout the Gulf Coast states. 
       

16. Linux Open source advocacy
    For a couple of days now I have been keeping track of a certain wordpress blog maintained by Ted Haeger. He is an open source evangelist who (in his own words) is working to motivate the Novell user community. And not surprisingly his blog is full of news related to SuSE Linux and how Novell is working with the open source community to bring a more polished Operating System to the users. But what caught my fancy was the interesting mockups screenshots he has posted of the "Computer Menu" of the upcoming SuSE enterprise desktop ver 10 which showcases a unique design deviating from the normal menu found in Gnome.

18. Novell to make SUSE Linux open-source
    Novell Inc. is planning to open up a version of its SUSE Linux operating system to users and developers, unveiling its OpenSUSE project at the LinuxWorld show next week in San Francisco, a company executive confirmed today. We're making OpenSUSE available for anyone, anywhere," said Greg Mancusi-Ungaro, marketing director for Linux and open source at Novell. "We've learned from customers that it's still very, very hard to get Linux unless you're a technical user. Novell will brand its SUSE Linux Professional flavor as SUSE Linux and will make the operating system open-source. The company will host those efforts at a new Web site, www.opensuse.org, which has not yet been
    launched according to Mancusi-Ungaro. "We're moving from a closed model, where the code was tested in-house, to a completely open and transparent model," where developers will have access to the source code and their input will be welcomed, he added. 
       

19. Linux: Open Source Software
    The motives (or at least the emphasis) of the people who use the term ``open source'' are sometimes different than those who use the term Free Software.'' The term ``open source software'' (a term championed by Eric Raymond) is often used by people who wish to stress aspects such as high reliability and flexibility of the resulting program as the primary motivation for developing such software. In a similar manner, the most widely used OSS/FS operating system is referred to by two names: ``GNU/Linux'' and simply ``Linux.'' ``GNU'' is pronounced guh-new
    and ``Linux'' rhymes with ``cynics.'' Technically, the name ``Linux'' is just the name of one system component (the ``kernel''), but often "Linux'' is used to mean the entire system.  
       

20. Linux and Open Source Blog
    Open document format is that new fileformat for Office suites, ISO certified and genuinely an open standard. Its been busy in ODF land, since early may the ISO certification came through we have seen the market accept this standard in an amazing speed. Governments are not well known for moving fast, and yet we have this long list of successes. Belgian government chooses Open Document, ODF in Denmark, Key India official endorses Open Document and naturally Massachusetts is still going strong. The ODF Alliance certainly is not sitting still either. Novell today announced two new innovative programs for Linux training designed to promote education around open source. Novell unveiled its ?Train the Teacher? series, the industry?s first free week-long boot camp for Linux* educators.
       

21. Basics for Adopting Linux/Open Source
    The adoption of a new platform is not something that happens overnight, especially in the corporate arena, where conservativism often makes the decision to change a slow and complicated process. There are shades of grey wrapped up in every decision--quite a contrast to the often black-and-white world of an IT worker. In that world, if something is broken, fix it. If it breaks repeatedly, re-code it (if you can) or replace it. These different approaches are probably the major issue behind getting corporations to look at Linux and other open source software seriously. It is not that they have a great love affair with Microsoft's products, but rather the fact that for decision-makers, Windows, for all its flaws and expense, represents that which is known. Linux represents the unknown and no amount of cajoling and endorsement from the IT staff is going to change their minds. Especially if the pro-Linux arguments are couched in technical jargonism that seems like a foreign language.
