Whatever you end up doing, could I ask you to send a note about it to the people behind GothamSchools.org. It's a slightly New York-centric education blog, but they work with people around the country on improving education, and I'm sure they'd love to know about anything you end up doing.

An In-Depth Look At Seagate's 1.5TB Barracuda 283

Posted by kdawson from the should-be-space-enough-for-anyone dept.
theraindog writes "More than a year and a half after the first terabyte hard drives became widely available, Seagate has reached the next storage capacity milestone. With 1.5 terabytes, the latest Barracuda 7200.11 serves up 50% more capacity than its peers, and at a surprisingly affordable $0.12 per gigabyte. But Seagate's decision to drop new platters into an old Barracuda shell may not have been a wise one. The Tech Report's in-depth review of the world's first 1.5TB hard drive shows that while the latest 'cuda is screaming fast in synthetic throughput drag races, poor real world write speeds ultimately tarnish its appeal."

Submission + - What mail server and setup do you run?

Submitted by
dmayle
dmayle writes: "I've been recently undergoing a deluge of spam on my personal mail server (serves me and my family), and I believe this to be the cause of some lost mails (Overloaded SpamAssassin). I've decided that it's time to migrate to a new server to take into account best practices, and I was wondering what the users of slashdot are using for mail? I'm currently running an aging Qmail setup with Dovecot for IMAPS, Roundcube for webmail, and Clamd and SpamAssassin for content filtering. I've published SPF records, but it doesn't seem to be any help, and I get hundreds of false bounce messages per day. Does it make any sense to implement DKIM/DomainKeys? So far, for my new setup, I've been wavering between Postfix and Exim as the MTA, keeping Dovecot and Roundcube, but switching to DSPAM for my spam filtering. What are you folks running on your mail servers, and how do you handle the spam deluge? I've heard about greylisting, but since I don't control my SMTP backup servers, I'm worried about that not working. What do you folks think?

P.S. Performance is an issue, as this will be running on a virtual server, so personally I don't plan to run Scalix or Zimbra. I've done my homework, and a lot of research, I'd just like to know what everyone here is using, or if I've missed some options, thanks."

amigoro writes: "Scientists have found a method to replace crude oil as the root source for plastic, fuels and scores of other industrial and household chemicals with inexpensive, nonpolluting renewable plant matter. They directly converted sugars ubiquitous in nature to an alternative source for those products that make oil so valuable, with very little of the residual impurities that have made the quest so daunting."

His trial is most likely to begin in October or September. Reiser stands accused of the murder of his wife, Nina Reiser, from whom he is separated.

Submission + - Weapon found in Whale blubber from the 1800's (cnn.com)

Submitted by LABarr
LABarr writes: AP and CNN are carrying this story. "A 50-ton bowhead whale caught off the Alaskan coast last month had a weapon fragment embedded in its neck that showed it survived a similar hunt — more than a century ago. Embedded deep under its blubber was a 3½-inch arrow-shaped projectile that has given researchers insight into the whale's age, estimated between 115 and 130 years old. The bomb lance fragment, lodged in a bone between the whale's neck and shoulder blade, was likely manufactured in New Bedford, on the southeast coast of Massachusetts, a major whaling center at that time. It was probably shot at the whale from a heavy shoulder gun around 1890." One tough whale...

Submission + - Is parallel programming just too hard?

Submitted by pcause
pcause writes: There has been a lot of talk recently about the need for programmers to shift paradigms and begin building more parallel applications and systems. The need to do this and the hardware and systems to support it have been around for a while, but we haven't seen a lot of progress. The article says that gaming systems have made progress, but MMOGs are typically years late and I'll bet part of the problem is trying to be more parallel/distributed.

Since this discussion has been going on for over a decade with little progress in terms of widespread change, one has to ask is parallel programming just too difficult for most programmers? Are the tools inadequate or perhaps is it that it is very difficult to think about parallel systems. Maybe it is a fundamental human limit. Will we really see progress in the next 10 years that matches the progress of the silicon?

On May 8, 2007, we were pleased to announce that checkers is now solved. From the standard starting position, Black (who moves first) is guaranteed a draw with perfect play. White (moving second) is also guaranteed a draw, regardless of what Black plays as the opening move. Checkers is the largest game that has been solved to date.

Submission + - Scientists create 'plastic' blood

Submitted by simm1701
simm1701 writes: This aricle on the BBC Writes about a new form of artifical blood.

From the article:
Scientists have developed an artificial plastic blood which could act as a substitute in emergencies.

Researchers at Sheffield University said their creation could be a huge advantage in war zones. They say that the artificial blood is light to carry, does not need to be kept cool and can be kept for longer. The new blood is made up of plastic molecules that have an iron atom at their core, like haemoglobin, that can carry oxygen through the body. The scientists said the artificial blood could be cheap to produce and they were looking for extra funding to develop a final prototype that would be suitable for biological testing.

Dr Lance Twyman, of the university's Department of Chemistry, said: "We are very excited about the potential for this product and about the fact that this could save lives. "Many people die from superficial wounds when they are trapped in an accident or are injured on the battlefield and can't get blood before they get to hospital. "This product can be stored a lot more easily than blood, meaning large quantities could be carried easily by ambulances and the armed forces."

A sample of the artificial blood prototype will be on display at the Science Museum in London from 22 May as part of an exhibition about the history of plastics.

Submission + - How To Run Cisco IOS On Your PC

Submitted by
An anonymous reader writes: Started in August of 2005 by Christophe Fillot, Dynamips is a Linux and Windows based application that is used to emulate the hardware of the Cisco 7200 and 3600 series routing platforms. Unlike traditional router simulators" Dynamips allows you to boot real Cisco IOS software images and build complex network topologies to test the functionality of IOS on your desktop PC. As of November 2006 Dynamips currently supports Ethernet, Serial, ATM, and POS interfaces for the 7200 series routers and Ethernet, Serial, and Etherswitch modules for the 3600 series routers. Best of all Dynamips is open-source and free to download!

To run Dynamips first you must install libpcap or winpcap depending on your platform. Windows users will need to install winpcap 4.0 or later which is currently in beta.

Next download the appropriate Linux or Windows executables for Dynamips. To do this I would recommended to download the Dynagen installer package, a front end written by Greg Anuzelli which uses an INI-like configuration file to provision the Dynamips emulator.

Next you'll need a Cisco IOS software image for a 7206, 3620, 3640, or 3660 router depending on which platform you will be emulating.
