Submission + - ZFS on Linux: It's alive! (

lymeca writes: LinuxWorld reports that Sun Microsystem's ZFS filesystem has been converted from its incanartion in OpenSolaris to a module capable of running in the Linux user-space filsystem project, FUSE. Because of the license incompatibilities with the Linux kernel, it has not yet been integrated for distribution within the kernel itself. This project, called ZFS on FUSE, aims to enable GNU/Linux users to use ZFS as a process in userspace, bypassing the legal barrier inherent in having the filesystem coded into the Linux kernel itself. Booting from a ZFS partition has been confirmed to work. The performance currently clocks in at about half as fast as XFS, but with all the success the NTFS-3g project has had creating a high performance FUSE implementation of the NTFS filesystem, there's hope that performance tweaking could yield a practical elimination of barriers for GNU/Linux users to make use of all that ZFS has to offer.

Submission + - Linux Chosen for Next-Generation Space Hardware (

EraserMouseMan writes: WindRiver has been chosen by Honeywell to develop a Linux-based solution to run on top of Honeywell's next-generation Dependable Multiprocessor for spacecraft.

"Any material put into space is subject to variable accelerations, mechanical shock and vibration, harsh vacuum conditions, extreme temperatures, and often, intense particle and electromagnetic radiation. Wind River Platform for Network Equipment, Linux Edition, running in conjunction with GoAhead SelfReliant Software, which provides high availability middleware, and Honeywell''s Dependable Multiprocessing Middleware on Extreme Engineering Solutions'' XPedite6031 boards, will support the demonstration of high availability and high reliability operation for the ST8 Dependable Multiprocessor experiment."

The relevancy and robustness of Linux is being recognized by the biggest players in industry for their mission critical needs. Is Linux finally being recognized as suitable for everything from putting men on Mars to defending our country?


Ancient Star Found, Estimated at 13.2 Billion Years Old 377

raguirre writes "An article on reports that a newly found star may be as old as the universe itself. Recent studies have concluded that the Big Bang occurred somewhere in the neighborhood of 13.7 Billion years ago. The star, a heavy-elements laden fossil labeled HE 1523-0901 on charts was probably born right around the same time; approximately 13.2 Billion years ago. 'Today, astronomer Anna Frebel of the the University of Texas at Austin McDonald Observatory and her colleagues have deduced the star's age based on the amounts of radioactive elements it contains compared to certain other "anchor" elements, specifically europium, osmium and iridium.'"

Submission + - Are .tmp files necessary or just bad programming?

planckscale writes: After spending another hour deleting .tmp files from a bloated XP machine I started to wonder, is the .tmp file necessary when coding an application on the MS platform? Why do so many apps produce .tmp files and is it just because of bad coding or does the use of them dramatically speed up an app? Don't coders use dev/null to reduce them in linux? I can understand the use of them in case an app crashes for recovery purposes, but why don't more apps have the capacity to delete their own .tmp files once they are done with them? Is it too much to ask to at least have the option when closing an app to delete your temp files?

Submission + - How do I get 4GB in Windows Vista?

javajeff writes: I decided to buy an extra 2 GB for my Windows Vista Ultimate. I installed the two new sticks, turned on the computer, and found that Windows only sees 3326MB. Apparently, 32 bit Windows will not see anything over 3.XGB due to memory mapping. Here is a Knowledge Base article from Microsoft: on the subject. My bios shows all the sticks installed, and I moved them around to make sure they were all working properly in a 2GB situation. I also ran Ubuntu off of the 7.04 CD to try, and it also did not detect all of the memory. I have an Intel Core 2 Duo Processor E6300 and an Intel Desktop Board DG965WH. My question to the Slashdot community: Is there any way to use 4GB without installing the 64 bit Vista Ultimate?

Submission + - When Windows Breaks

SpiritGod21 writes: "Computer World recently posted a story about the automatic updates bug in Microsoft Windows causing systems to lock up. In the labs I administrate, I simply disabled automatic updates and am updating the image manually, then pushing that image to the lab. How do others deal with Windows-centered workplaces when Windows breaks?"

Submission + - Pros and cons of starting a career in OS Support

Sri writes: "Hi, I am a Computer Science graduate and I've been recruited by a company for their OS support team. (And no , it's not a company based in Redmond!) The work involves a lot of system side maintenance(bug fixing /code changes etc) in C/Assembly language and also solving customers' problems. What advantages does this kind of work offer over say development/QA? What lessons from this work can I take away if I decide to switch to development on a new platform?"

Submission + - HP Recruiting using Second Life

virtualJobsGetPaidVirtualMoney writes: A Computer Science student graduating with a bachelor's degree looking for a full-time position has been contacted by HP for an virtual interview.

Representatives from Hewlett Packard have released the following opportunity. HP will be interviewing in the virtual world for real-world jobs! This is a first for HP and encourage students to try it out, especially if they are already Second Life players.
Interviewing is already so subjective, would this method of interviewing truly yield a qualified candidate?
Data Storage

Submission + - Removable drive Filesystem for Linux and Windows

kishore.avv writes: Wonder which filesystem /.'ers use for their removable drives (with large numbers of small files), for windows and linux. NTFS is unstable on linux and YAReG/etc. are unstable for large number of files. Is there any really good journaling file system providing driver level (even user level is tolerable) but stable, operation for both operating systems? Googling does not help very much here.

Submission + - Documentation to Code in Second Life

Cowgirl writes: The developer documentation in the Second Life client takes the form of a wiki, making documentation easier. In Part 2 of the ongoing exploration of the Second Life software, take a look at that documentation, and use it to jump-start some modifications to the client.

Submission + - Is America still free?

chameleon3 writes: Slashdotters are wont to bemoan the slow erosion of personal freedoms in the United States, and I am not inclined to disagree. My question is: how will you know that America is no longer the Land of the Free? What event would be necessary for you to declare Freedom officially dead in America? Or, if you believe it has already occurred, what event caused it?

Cable Packet Shaping Causing Slowdowns 356

knorthern knight writes "To counter P2P programs that encrypt their traffic to evade detection, Rogers Cable in Canada has apparently started degrading all encrypted IP traffic, according to a post on Michael Geist's blog. How many of you log in to work over a VPN or ssh-tunnel? How many get usenet news or email over an encrypted connection? This could be a problem for Rogers Cable customers. Geist, who teaches at U of Ottawa, has 'been advised that the University computer help desk has received a steady stream of complaints from Rogers customers about off-campus email service.'"
