Have a look at Linux kernel source from a bird's eye view. The Linux kernel is one of the most mysterious open source projects. There is a lot of documentation, however it is still a difficult subject to comprehend. The Interactive Linux kernel map is intended to help people gain an overview of the structure and interactions of the Linux Kernel. This approach is similar to classic operating system diagrams in which application and user space interfaces are at the top, hardware interfaces and drivers are at the bottom and separate functions are shown in vertical bars

Sun today announced the yet-to-launch JavaFX programming language will gather data on end-users activities to help developers monetize software, by selling ads for instance. The company's Project Insight will see "instrumentation" added to PCs, mobiles and Blu-ray devices that run JavaFX, which feed data back through a special data stream to a hosted service. Codenamed Project Hydrazine, the service is run by Sun for the benefit of third parties.

Yesterday, I wrote in a comment that indeed Sun's performance in 2003 in signing the agreement with SCO, highlighted in the trial testimony, was making it look really bad. The motive in doing it seemed to me to be not just to open source Solaris but to also hobble Linux and promote a competitive product instead, and in the ugliest way possible. And then, when they had to power to stand up to SCO and protect Linux end users, they failed to do so.

Ext4 is the latest in a long line of Linux file systems, and it's likely to be as important and popular as its predecessors. As a Linux system administrator, you should be aware of the advantages, disadvantages, and basic steps for migrating to ext4. This article explains when to adopt ext4, how to adapt traditional file system maintenance tool usage to ext4, and how to get the most out of the file system.

Thomas Beale, Chair of the openEHR Foundation Architecture Review Board (ARB) has posted a message describing some goals for the coming year. These include a vision, roadmap and strategies for the architecture and clinical modeling.

Google is spearheading a volunteer workforce it hopes will become the centralized authority for responding to security issues in open source software. oCERT, short for the open source computer emergency response team, will aim to remediate security vulnerabilities and exploits in a wide range of open source programs by coordinating communication among publishers. According to Google's security blog, the group "will strive to contact software authors with all security reports and aid in debugging and patching, especially in cases where the author, or the reporter, doesn't have a background in security."

Ubuntu 8.04 LTS (long-term support) launched on April 24th for desktops and servers. There is something for everyone in this version, but the LTS release will have particular appeal to enterprises. As one corporate user said to me, "I have been waiting for the release of Ubuntu 8.04, because I am using Ubuntu 6.06 on my company laptop and we have to install exclusively long term support releases." The LTS release assures a reliable upgrade paths twice a year with security updates maintained for a full five years.

Now that a solid foundation for the OpenSolaris project is in place, the real work of putting Sun and Solaris back into the center of the IT conversation can commence. It's been nearly three years since Sun Microsystems kicked off its OpenSolaris project by releasing most of the code that comprises its Solaris operating system under an open-source license. And yet, it's only just now, with the release of the first official distribution of OpenSolaris, that the project begins in earnest.

For many years, there has been a growing concern about the emergence of a “digital divide” between rich and poor. The idea is that people who don’t meet a certain threshold income won’t be able to afford the investment in computers and internet connectivity that makes further learning and development possible. They’ll become trapped by their circumstances. Under proprietary commercial operating systems, which impose a kind of plateau on the cost of computer systems, this may well be true. But GNU/Linux, continuously improving hardware, and a community commitment to bringing technology down to cost instead of just up to spec, has led to a new wave of ultra-low-cost computers, starting with the One Laptop Per Child’s XO. These free-software-based computers will be the first introduction to computing for millions of new users, and that foretells a much freer future. read more here

The comments on the single distro story got me thinking about what I want/need/use. I have been using Linux since before Bill Gates heard of it and my uses, needs and interests have changed over time. Ten or more years ago I was in the "I need to get Linux to do X" mode. That included a web server, an office network and a bunch of desktops—some for geeks but also some for the rest of the office including the shipping clerk and the receptionist.

From the presentation, you might imagine that Adobe's announcement of the Open Screen Project was major news. According to the news release, the project's goal is "to enable a consistent runtime environment" by relaxing some restrictions on the Flash format and releasing some specifications. However, in the free Flash community, the small group of developers dedicated to producing non-proprietary Flash tools, the reaction to the news was polite at best -- and serves as a much-needed reality check to the over-enthusiastic announcement.

Sun and OpenSolaris.org on Monday released the first publicly available version of the OpenSolaris operating system since work on the project began in 2005. The operasting system, which is a single distribution that can be used for desktop, server and HPC deployments, is based on the Solaris kernel and uses Sun's ZFS as the default file system.

Purchase a new PC or motherboard soon, and the chances are good that it will come with two built-in network interfaces -- either two Ethernet jacks or one Ethernet and one Wi-Fi. Tossing in a second adapter is an inexpensive way for the manufacturer to add another bullet point to the product description -- but what exactly are you supposed to do with it? If you are running Linux, you have several alternatives.

One of the items on the Geek Ranch agenda is a weather station. While we don't have one yet, we have learned a bit about weather stations and Linux.First, why don't we have one? Well, there is no electricity at the Geek Ranch site yet for starters. But, more important, there is no Internet connection. So, let's just call this research.

Two months ago we had looked at the Tyan Tempest i5400XT motherboard, which was Tyan's latest product based upon Intel's newest workstation chipset and had support for dual Intel Xeon quad-core processors. We found the Tempest i5400XT to be a real winner and everything had worked terrific with Linux. Today we are looking at another Tyan workstation motherboard but the tides have turned as we look at their latest AMD dual quad-core solution, the Tyan Thunder n3600M. The Thunder n3600M motherboard supports dual AMD "Barcelona" Opteron processors, 16 sticks of DDR2 RAM, and eight SAS ports, among other stunning features.

Ubuntu 8.04 offers several choices for FTP servers. However, VSFTPD is a great choice based on the secure design and enhanced SSL support for making connections.

The relationship between business, vendors and coders has been tested at a Sun Microsystems conference in San Francisco intended to express oneness with open source. Ian Murdock, Sun vice president of developer and community marketing, and Marten Mickos, head of Sun's database group, used CommunityOne to outline Sun's ideals on recent acquisition MySQL, OpenSolaris and NetBeans. At the same time they explained Sun's attempts to monetize them.

After several weeks of delay, the First Issue (2nd Volume) of THE *NIXED REPORT is now available. Of interest to FOSS users is a previously unpublished blog entry from helios.

Your editor is not always known for making life easy for himself. Perhaps one of the most clear examples of masochistic behavior would be a certain preference for running development distributions on mission-critical systems. That said, your editor has stuck with a stable distribution on his laptop through a round of intensive travel earlier this year. But that was too easy, so, shortly before heading off to the Linux Foundation's Collaboration Summit, the laptop got moved to the Ubuntu "Hardy Heron" distribution. Needless to say, there have been some interesting ups and downs (literally) since then.

More people are converting to Linux platform and it seems that they are not regretting the conversion. It was after the church service when there was a tap on my shoulder. "Hey Neil, just letting you know that you converted me" said the voice. I turned around. There before me was Gary (not his real name), a member of our church. Before I had the brainpower to wonder why it was that a Christian in our church had just announced that I had converted him, he continued. "I'm using Linux"
