New features include virtualization memory de-duplication, a rewrite of the writeback code faster and more scalable, many important Btrfs improvements and speedups, ATI R600/R700 3D and KMS support and other graphic improvements, a CFQ low latency mode, tracing improvements including a 'perf timechart' tool that tries to be a better bootchart, soft limits in the memory controller, support for the S+Core architecture, support for Intel Moorestown and its new firmware interface, run-time power management support, and many other improvements and new drivers.

Submission + - netboot.me: Turning 'netboot' into 'internetboot' (netboot.me)

Submitted by
Nick Johnson
Nick Johnson writes: "Netboot.me takes regular netbooting and makes it a whole lot more versatile — now, you can netboot directly into the installers for many popular linux distros, as well as system tools and even live linux distributions, all directly over the Internet, and without any local configuration required!

All that's required to set up netboot.me is a spare writable CD, USB key, or floppy disk to write a small (less than 1MB) disk image to. Alternately, determined geeks can change their DHCP server to allow computers to netboot directly. Once you've done that, booting off the device on any computer with wired ethernet (wifi is a work in progress) will automatically cause the bootloader to download the current version of the menu from netboot.me, which you can then find the boot image you want to boot from. Selecting it causes the boot image to be downloaded and booted immediately.

Best of all, netboot.me lets you add your own boot configurations; once you've tested them, and if they're of general interest, you can file a bug to have them included in the menu system. netboot.me is capable of booting any linux kernel and any other standard boot image, as well as disk images and CD images, thanks to syslinux's memdisk.

The getting started and help pages have many more details on how to use netboot.me, and how to contribute to it. The more boot images in the system the better, so contributions are much appreciated."

Comment Re:Does Brother Make Any Label Printers? (Score 2, Informative) 188

by kinko (#28891705) Attached to: Linux-Friendly Label Printer Recomendations?

Yes, we use the Brother P-Touch QL-550. It works fine with CUPS but we had to install a 3rd party (open source) driver for it that converts the postscript input from applications into the correct raster format for the printer.

Driver here: http://etc.nkadesign.com/Printers/QL550LabelPrinterCUPS. Brother also release a binary-only driver, but why use that when an open source one works....

DHCP Management Across a Diversified Network? 100

Posted by timothy from the send-that-packet-that-way dept.
ET Admin writes "I work for a small Wireless ISP, where we are deploying new network hardware to allow for growth and contain broadcast traffic. All routing/switching equipment is Cisco. We use Linux stand-alone boxes and VMs (running on Win 2003 boxes). We have decided on a hybrid VLAN layout where we have certain VLANs limited by location, and other VLANs that are global across the network. And I want DHCP served across it all. Does anyone have experience with IPAM software that handles multiple DHCP servers? Our network is small so spending a couple grand is overkill at this point. Any recomendations to help me decide between serving DHCP from the Nix boxes, or from the Cisco gear? Knowing that a single DHCP server will handle from 100-500 hosts."

Submission + - EVE Online update corrupts Windows installations

Submitted by
An anonymous reader writes: The recent EVE Online expansion, Trinity, appears to have an unbelievably nasty bug that makes one question whether the publisher, CCP, has any QA at all; a typo in the patch results in C:\boot.ini being deleted. The patcher adds an extra backslash onto a delete command for "boot.ini" resulting in "\boot.ini", which if the game is installed on C: refers to Windows' boot.ini file. Hundreds of players have reported their computers being unable to boot, and tens of thousands more will likely encounter the same problem when they attempt to turn on their computer tomorrow. Oops?

Submission + - EVE Online Expansion Renders Computers Unbootable

Submitted by
Chuu
Chuu writes: "Today EVE Online launched a major expansion named 'Trinity' which included a major engine overhaul. The problem is that because of a bug in the install script, the graphics add-on deletes the system's boot.ini file which renders the system unbootable. There is no official word from CCP about this yet, however many large alliances in game and individuals in the official forums have confirmed the bug. Some discussion about the bug and what to do if effected is here."

Even worse than not being able to log in and access mail, email sent to these accounts is being bounced. Google has not responded at this time.

Submitted by Anonymous Coward
An anonymous reader writes: OpenArena is a project designed to provide a free Quake 3 experience. While the source for Quake 3 is free, the data is not so OpenArena is making all new Q3A compatible data to go with an upgraded engine. Many existing Q3A maps and mods already work fine but the project needs your support. 0.70 is available for Windows, Linux and MacOSX and is mirrored at many popular sites. Try it out, and contribute if you can.

Submission + - Can CDs Be Recycled?

Submitted by
An anonymous reader writes: I was recently doing a closet-cleaning and came across literally hundreds of old software CDs that are no longer usable — both manufactured CDs and CD-Rs. Note that by "not usable", I mean that many of them simply couldn't be read anymore, possibly due to the fact that they'd been stored rather ineptly (no, I wasn't responsible for how they were stored). My question is: Is it possible to reclaim CDs for raw materials? It seems wrong to just throw them out, but are there other things that can be done with them that will allow their raw materials to be reused in some way?

Submission + - Bionic eye could restore vision

Submitted by

MattSparkes writes: "A new bionic eye could restore vision to the profoundly blind. A prototype was tested on six patients and "within a few weeks all could detect light, identify objects and even perceive motion again. For one patient, this was the first time he had seen anything in half a century." The user wears a pair of glasses that contain a miniature camera and that wirelessly transmits video to a cellphone-sized computer in the wearer's pocket. This computer processes the image information and wirelessly transmits it to a tiny electronic receiver implanted in the wearer's head."

Submission + - Vista "express" upgrade program bungled

Submitted by Josh M.
Josh M. writes: Thousands of customers who purchased new Windows PCs this past Christmas are still waiting on their promised Windows Vista upgrades, despite the Vista launch occurring more than two weeks ago. Ars reports that Dell and HP have both pushed their shipping dates 6-8 weeks back after launch, meaning some people won't get their upgrades well into April. It turns out that because those customers get free Vista support, the OEMs are waiting for better driver support, hence the delay. So much for "express."

Submission + - Data centers sucking down electricity bigtime

Submitted by

BobB writes: "Energy consumption in corporate data centers doubled between 2000 and 2005, due in large part to the spreading use of volume servers, according to a new report. The study, conducted by a staff scientist at Lawrence Berkeley National Laboratories and a consulting professor at Stanford University, found that servers and associated infrastructure, such as cooling and uninterruptible power supplies, in U.S. data centers consumed about 45 billion kilowatt hours of electricity in 2005, accounting for about 1.2% of the country's electricity consumption, roughly equal to the power drawn by the nation's color televisions. The electricity costs for the servers and associated infrastructure reached $2.7 billion. http://www.networkworld.com/news/2007/021507-study .html"
