Good news and great contribution from HP. You can study all those advanced features for academic project.
AdvFS is a file system that was developed by Digital Equipment Corp and continues to be part of HP's
Tru64 operating system. It offers many advanced features. Continuing its efforts to advance customer adoption of Linux, HP today announced the contribution of its Tru64 UNIX Advanced File System (AdvFS) source code to the open source community. The code on this site is licensed under the GPLv2 to be compatible with the Linux kernel.
The AdvFS source code includes capabilities that increase uptime, enhance security and help ensure maximum performance of Linux file systems. HP will contribute the code as a reference implementation of an enterprise Linux file system under the terms of General Public License Version 2 for compatibility with the Linux kernel, as well as provide design documentation, test suites and engineering resources.
Now the million dollar question - Is there any reason to pick AdvFS fs over any of the other 20+ file systems such as XFS/ext2/ext3 under Linux?
According to new independent tests Red Hat Linux pulls as much as 12% less power than Windows 2008 on identical hardware. It means Linux is better for reducing data center power consumption or electrical power consumption. From the report:
Our tests point to Linux as the winner of the green flag by margins that topped out at 12%. We ran multiple power consumption tests using Windows Server 2008 Enterprise Edition, Red Hat's Enterprise Linux (RHEL) 5.1 and SUSE Enterprise Linux 10 SP1 on four, popular 1U server machines, one each from Dell and IBM and two from HP. The results showed that while Windows Server 2008 drew slightly less power in a few test cases when it had its maximum power saving settings turned on, it was RHEL that did the best job of keeping the power draw in check across the board.

Now the million dollar question, how important is green computing / green computers to you? Would you make switch to save the power?
Asus dominates the market for super small, super cheap Linux / XP based mini-notebook pc. It is believed that they may have sold over 5 million Eee PCs. Now you can grab this PC for free. Royal Bank of Canada (RBC) is running spring 2008 promotion and giving out a free Asus EEE PC for every new account opened with them. Similarly you can signup to T-Mobile's 'Web n Walk' max mobile boradband package for £35 per month ona 24 month contract and get a free USB modem and a free Asus EEE PC ultra mobile PC.
It turns out that people just wanted a regular laptop, but much smaller and cheaper. When Asus came out with its mostly solid state, plain vanilla PC running Linux (and now XP), the masses flocked. And now, Acer, Dell, HP and possibly Sony, as well as a smattering of smaller companies, are rushing their own cheap-and-tiny offerings.

Check out this awesome post about all tiny device powered by Linux!
Over the past six months or so, Asus, Everex, and HP have managed to bring low-cost ultraportable notebooks to market. But dozens of other computer makers have promised to bring out their own mini-notebooks. Some will run Linux, while others will be preloaded with Windows XP or Vista. Some will have flash memory, while others will have hard drives. But every one will be smaller, lighter, and cheaper than most existing laptop computers. Here's a roundup of some of the computers that have been announced or are already available.

To help schools offer affordable computing to every student, HP today introduced a full-function, mini-notebook Linux powered PC priced starting under $500. HP will join a fledgling market already populated with products from Intel Corp., the world's largest semiconductor company, and Asustek Computers Inc., the world's largest maker of computer motherboards.
The only way to keep cost is use Linux and create network only computer for everybody. Windows vista cannot be installed because of price tag and higher hardware requirements.
- Simple, refined design and anodized aluminum shell that is sleek and sturdy yet lightweight;
HP DuraKeys, featuring a clear coating applied over the notebook keyboard that protects the finish and printed letters and characters;
- An HP 3D DriveGuard, which sends a signal to shut down the hard drive upon sudden movement or shock by using a three-axis digital accelerometer chip
- Scratch-resistant display and magnesium hinge bracket
- A large 8.9-inch diagonal WXGA display, user-friendly full keyboard (QWERTY) and touchpad;
- Ability to view video, still-image capture, web conferencing or video-enhanced instant messaging with no additional hardware to buy or carry. An optional integrated VGA webcam enables video and still-image capture to allow the addition of photos and video clips to presentations, documents and email;
- Two battery solutions – three-cell for lightest-weight configurations or optional six-cell for longer battery life;
- Wireless technologies such as integrated Wi-Fi Certified WLAN(3) and optional Bluetooth™, allowing students to access the Internet as well as communicate via email, IM, chat, VOIP and blogging. The wireless technologies also enable connections at hotspots as well as with Bluetooth devices such as printers, mice and headsets; and
- The processors HP is using are made by Via Technologies Inc., the distant third-ranked player in the microprocessor space, and come in clock speeds up to 1.6 gigahertz.

From my mail bag:
Where can I get free interactive access to HP-UX or Linux distro or UNIX shell access?
You can simply grab and try out any Linux / BSD / Solaris Live CD. However, some time you cannot install and use particular UNIX like os. So, if you want to try the latest technologies over the Internet? Try HP TestDrive program:
This program allows you to testdrive some of the hottest hardware and operating systems available today. Have you ever wanted to try out HP's exciting 64-bit Integrity and PA-RISC technology? Get time on SMP x86 and Opteron ProLiant servers? Try out a Blade server. Try different Open Source operating systems such as FreeBSD, Suse, Redhat, Debian and other Linux distributions.
This program is perfect for students and new users to try out and learn basis of UNIX. You can also try and test your C/C++ programs using latest Intel compilers. It is intended for those users who want to sample the 32- and 64-bit servers running a variety of HP, UNIX, Linux and third-party operating systems and applications.

This is an interesting idea. You can get instant access to your Linux desktop at anytime from within Microsoft Windows. This article will tell you everything you need to know in order to make a USB flash drive with Ubuntu Linux installed. You need:
- Obviously you need a USB flash drive (at least 2GB).
- You'll need a working computer running Microsoft Windows with a USB port available.
- A copy of the Ubuntu 6.10 Edgy .ISO file (it's 750MB).
- A copy of Qemu (this is the program that allows Ubuntu to actually run on Windows).
- A copy of Kqemu accelerator. This helps Qemu speed up Ubuntu.
- A copy of startubuntu.tar - This file holds two custom batch and img files.
- The HP-USB format tool to clear your USB drive.
