CentOS is a community-supported, freely-available operating system based on Red Hat Enterprise Linux. Lance Davis created CentOS and now he goes absent without leave. In an open letter from his fellow CentOS developers:
You have long promised a statement of CentOS project funds; to this date this has not appeared. You hold sole control of the centos.org domain with no deputy; this is not proper. You have, it seems, sole ‘Founders’ rights in the IRC channels with no deputy ; this is not proper.

This is an interesting visualization techniques for software analysis. From the article:
Despite being a very important part of any operating system, file systems tend to get little attention. The first part is a detail analysis of one particular Linux Kernel tree and the second is a shorter one done over a large number of file systems from Linux Kernel 2.6.0 to 2.6.29. After that there is a small section that shows some aspects of the BSD family. After conclusions there is an appendix consisting of three things: the first one explains how the file systems for Linux were compiled, the second one shows timelines for the releases of Linux Kernel, FreeBSD, NetBSD and OpenBSD; the last is a detailed map of the external symbols of the kernel modules analyzed in the second section.

MAC Filtering (layer 2 address filtering) refers to a security access control methodology whereby the 48-bit address assigned to each network card is used to determine access to the network. Iptables, pf, and IPFW can block a certain MAC address on a network, just like an IP. One can deny or allow from MAC address like 00:1e:2a:47:42:8d using open source firewalls. MAC address filtering is often used to secure LAN or wireless network / devices. Is this technique effective?

The Linux Foundation is launching a video contest and you can win yourself a trip to Tokyo next year to participate in the Linux Foundation Japan Linux Symposium Oct, 2009.
If you’ve been alive and aware of mass media over the last twelve months, you’ve probably seen television commercials from Apple and Microsoft touting their operating system. From Apple’s ubiquitous “I’m a Mac” to Jerry Seinfeld to Microsoft’s “I’m a PC” retort, operating system commercials have been flooding the airways. Except one OS has been notably absent â€“ Linux.
You can upload your contest video here.
Wow.. a completely ignorant teacher. This clearly demonstrate problem faced by GNU/Linux in class room.
A teacher (from Austin, TX) came to students and confiscated the Linux Live CDs. Next, she wrote an angry email to HeliOS’s project founder, Ken Starks:
After confiscating the disks I called a confrence with the student and that is how I came to discover you and your organization. Mr. Starks, I am sure you strongly believe in what you are doing but I cannot either support your efforts or allow them to happen in my classroom. At this point, I am not sure what you are doing is legal. No software is free and spreading that misconception is harmful. These children look up to adults for guidance and discipline. I will research this as time allows and I want to assure you, if you are doing anything illegal, I will pursue charges as the law allows. Mr. Starks, I along with many others tried Linux during college and I assure you, the claims you make are grossly over-stated and hinge on falsehoods. I admire your attempts in getting computers in the hands of disadvantaged people but putting linux on these machines is holding our kids back.
This is a world where Windows runs on virtually every computer and putting on a carnival show for an operating system is not helping these children at all. I am sure if you contacted Microsoft, they would be more than happy to supply you with copies of an older verison of Windows and that way, your computers would actually be of service to those receiving them
Read on ken’s reply: Linux – Stop holding our kids back
Perhaps, some one need to educate the teacher and point out that Linux is being used by governments, private & public corporations, and millions of embedded home appliances are powered by Linux.
Update – Dec., 12 2008: This matter is now closed and the student did get back Linux CDs after the class.
Updated for accuracy!
Today Ubuntu Linux 8.10 final will be released to all mirrors world wild. However, FTP/HTTP mirrors server may down due to heavy demands from users. You can now use BitTorrent to upgrade Ubuntu Linux to 8.10 from old 8.04 version. Help Ubuntu project to spread Linux to humanity.
In the past, the update servers would crash very quickly on a big release day, making it hard for people to get the latest update. With BitTorrent, however, this can be easily avoided.
Most users of Linux based operating systems such as Ubuntu are familiar with BitTorrent. In fact, Ubuntu even comes with a BitTorrent client, and millions of Ubuntu users got their install disk via the popular filesharing protocol.
