Future of the Screen: After the CRT, a Display Deluge By Jon Stokes | 09.02.09 For the seven decades following the debut of television at the 1933 Chicago World's Fair, the term "cathode ray tube" (CRT) was virtually synonymous with "display." Shortly after the turn of the millennium, liquid crystal display (LCD) technology began to replace the venerable CRT in desktop-computer applications, and by the middle of the decade LCD was rapidly squeezing the CRT out the television market that the latter had invented. Just two years ago, it seemed obvious that the display space was in the final stages of a relatively straightforward evolutionary shift, with LCD replacing the CRT in the same way that the gas-powered automobile had replaced the horse and buggy.
At Backblaze, we provide unlimited storage to our customers for only $5 per month, so we had to figure out how to store hundreds of petabytes of customer data in a reliable, scalable way—and keep our costs low. After looking at several overpriced commercial solutions, we decided to build our own custom Backblaze Storage Pods: 67 terabyte 4U servers for $7,867. In this post, we’ll share how to make one of these storage pods, and you’re welcome to use this design. Our hope is that by sharing, others can benefit and, ultimately, refine this concept and send improvements back to us. Evolving and lowering costs is critical to our continuing success at Backblaze. Below is a video that shows a 3-D model of the Backblaze Storage Pod. Continue reading to learn the exact details of the design

It costs more than three times as much to publish an article in a humanities or social-science journal as it does to publish one in a science, technical, or medical, or STM, journal, and the prevailing model used by many publishers of STM journals will not work for their humanities and social-sciences counterparts. Those are some of the eye-opening conclusions released today in a report on an in-depth study of eight flagship journals in the humanities and social sciences.
In my last project at work, I had to replace NFS with GFS2 and Clustering. So in this tutorial I will show you how to create a Red Hat or CentOS cluster with GFS2. I will also show you how to optimize GFS2 performance in the next HowTo, because you will quickly notice some loss of performance until you do a little optimization first.I will 1st show you how do build a Cluster with GFS2 on the Command Line and in the next tutorial I will show you how to do the same thing using Conga.

VMware to xen migration German original: http://www.eisxen.org/49.html To convert a Linux VMWare Image to a normal image, below the most important commands: install qemu convert the VMware image to a RAW-Image qemu-img convert -f vmdk /var/vmware/vm/vm01.vmdk \ -O raw /tmp/vmimage.raw A vmware imange is a containerfile. The partitions have to be spilt up to individual images for xen. To find out what is in the VMware image, take a look with: fdisk -l -u /home/xen/vmimage.raw Device Boot Start End Blocks Id System linux1 * 63 208844 104391 83 Linux linux2 208845 7550549 3670852 83 Linux linux3 7550550 8193149 321300 82 Linux swap I presume there are already some lvm’s available. Now use the command below a couple times to extract them dd if=vmimage.raw of=/dev/vg01/xendomU01slash bs=512 skip=208845 count=7341705 Of course, check the result (with a (loop)mount)
Re: How migrate vmware guest to xen Hi, It's possible with the qemu tools Install the qemu package (which is available from the OpenSuSE Build Service) and use the following command: qemu-img convert -f vmdk /path/to/vm01.vmdk -O raw /tmp/xenimage.raw This will create a raw disk which can be used with xen from a VMware vmdk disk.
The United States increasingly relies on information networks for the conduct of vital business. These networks are potentially subject to major disruptions from a variety of external sources. To date, there has been no clear statement of the magnitude of this threat or the ability of the various networks to withstand or respond to such disruptions. This project examines the national communications and information infrastructure. The research was conducted for the Office of Science and Technology Policy with task funding from the National Science Foundation.
As computational scientists are confronted with increasingly massive datasets from supercomputing simulations and experiments, one of the biggest challenges is having the right tools to gain scientific insight from the data. One common method for gaining insight is to use scientific visualization, which transforms abstract data into more readily comprehensible images using advanced computer software and computer graphics. But the ever-growing size of scientific datasets presents a significant challenge to modern scientific visualization tools. As a result, there is a great deal of motivation to explore use of large, parallel resources, such as those at the U.S. Department of Energy's (DOE) supercomputing centers, to take advantage of their vast computational processing power, I/O bandwidth and large memory footprint.
With Fibre Channel too expensive for most customers, the Internet Small Computer Systems Interface (iSCSI) protocol is poised to become the standard for architecting dedicated storage solutions. Small-to-medium businesses (SMBs) and enterprise customers alike should prepare for the inevitable adoption of iSCSI by encouraging their information technology staff to learn how to install and configure iSCSI today.

The Street's Scott Moritz reports that Apple is planning to release its long-rumored tablet computer "in time for the holidays" later this year. While Apple is reportedly still deciding on a sales model for the new device, Moritz's source reports that initial plans include subsidies from Verizon in order to lock in users for multi-year wireless data contracts while bringing down the upfront cost to consumers for the device, which is expected to carry a premium price tag.
"This project," said Sergiu Sanielevici, PSC director of scientific applications and user support, who also leads user support and services for the TeraGrid, "exemplifies how powerful systems like Pople can open doors to data-mining and data-centric research in fields not traditionally associated with HPC, such as the social sciences, and make it possible to get answers that would otherwise be impractical or impossible." PSC supported this project through the NSF TeraGrid program, which allocates large-scale computing resources free to researchers at U.S. universities on a peer-review proposal basis.

Evolution of Google File System August 08, 2009 07:26:40 EDT There is an interesting interview about the evolution of the Google File System in ACM Queue. I think it is readable by anybody, not just ACM members. One of the morals of this story is that, even if you are building what you think will be the world's biggest, you still will make design decisions that you know are not scalable because you know how to implement them. It is better to get something running right away and start using it. Of course, they also ran into scalability problems that they did not expect. So, some of the evolution of GFS was planned, and some was unplanned.
So you have heard of all the advantages and geeky babble about how Linux is better and you have finally decided to try it? Just one thing, you don’t know an awful lot about Linux to get you started. How about some free downloadable ebooks to teach yourself Linux, that you can download today? Would that help? Free – you ask? Yes, free. Welcome to the world of Linux where things are free both as in free speech and also as in free beer (mostly)!
Personal supercomputers that lash together a stack of graphics processing units and can sit on a desktop are becoming popular with researchers. These machines can be used to run calculations by the desk instead of waiting for time on one of the national supercomputers.
SUSE Studio is a free, web-based service designed to build virtual appliances, such as pre-installed hardware-appliances, or "software appliances" -- pre-configured Linux server stacks suitable for installation by users on real or virtual commodity hardware. Recently released from beta, SUSE Studio can produce appliance images in raw disk image, Live CD/DVD iso, VMware, and Xen formats, and there are plans in the works for supporting Amazon's EC2 ami format, says the review by our sister publication, eWEEK.

Before specialized graphics-processing chips existed, pioneers in the field of visualization used multicore supercomputers to realize data in three dimensions. Today, however, the speed at which supercomputers can process data is rapidly outstripping the speed at which they can input and output that data. Graphics-processing clusters are becoming obsolete.
