Submission + - Email Systems 5

OneC0de writes: I have been the IT admin for a small/medium business for the last 3+ years. Currently our email system is a IMAP/POP/SMTP setup hosted through another company across the country. We've continually had email problems ranging from dropped connections, and missed messages, to our host forcing our users to a 500MB inbox which we regularly have to flush. We have Small Business Server 2008 in-house running our active directory/group policy. I have normally setup Exchange on SBS for most of my clients but this business in particular is pretty against Exchange (being a Windows product). The owners are ready to upgrade their email system, but are not sold on going to Exchange. Many users at this company are on Thunderbird and don't want to make the switch to Outlook. The owners have asked me to find other email server solutions. One thing their "Linux friend" suggested was iRedMail. They definitely want to host it in-house to save on cost and increase connectivity while at the main office where most emails are done. Many users in the office have 2GB — 10GB of emails stored from the last 7+ years, just on their local machines (not being backed up regularly). Right now there is no shared calendars, or global contact list but they don't see that as a much needed feature anyways. We also use SquirrelMail 1.49 for web access, but it seems old and outdated.

So I guess my question is, are there open-source, or cheap mail servers you would recommend? Is there a good argument for Exchange other than (it's free and sitting in your server room right now, just need to "turn it on")? Would you recommend Exchange or go against it? One of the things the owners would like is anti-spam, anti-virus, and maybe some kind of archiving capabilities. Many users in the office also have mobile phones and would like access to the emails while on the go. Suggestions, comments, complaints, free beer?

Submission + - Researcher causes Endless Restart Loop on Samsung TVs (

Gunkerty Jeb writes: Italian security researcher Luigi Auriemma was trying to play a trick on his brother when he accidentally discovered two vulnerabilities in all current versions of Samsung TVs and Blu-Ray systems that could allow an attacker to gain remote access to those devices.

Auriemma claims that the vulnerabilities will affect all Samsung devices with support for remote controllers, and that the vulnerable protocol is on both TVs and Blu-Ray enabled devices.

One of the bugs leads to a loop of endless restarts while the other could cause a potential buffer overflow.

Submission + - Over-the-counter Drugs can Prevent Migraines

An anonymous reader writes: Migraines can be prevented by using certain medications, but very few actually use them, say the guidelines published by the American Academy of Neurology and the American Headache Society. Seven prescription drugs and one herbal remedy have been listed as effective in preventing migraines in at least 38 percent of the estimated 35 million Americans who suffer from these debilitating headaches.

Submission + - Facebook blocks add-on because it's too good at cleaning up Facebook (

the saltydog writes: A developer came up with a browser add-on to help customize the view on Facebook; first, they made him change the name — then, they blocked links to his site (as being "spammy" — which is an utter joke, as the add-on REMOVES all the spam from Facebook)... Now, they're arbitrarily removing photos in the albums on his page. In case you don't believe it, try sending any of your FB friends a link to — it will not work.

It's our data, and our machines — shouldn't we be able to arrange things the way WE want to see them? Fuck Facebook.
(From a happy user of the add-on.)

Submission + - Travelling Salesman - A Movie About P=NP (

mikejuk writes: A movie that features science and technology is always welcome, but is it not often we have one that focuses on computer science. Travelling Salesman is just such a rare movie. As you can guess from its name, it is about the Travelling Salesman problem, more precisely about the P=NP question. Written and directed by Timothy Lanzone, and produced by Fretboard Pictures, it should premiere on June 16.
As the blurb to the movie trailer says:
"Travelling Salesman is an intellectual thriller about four of the world's smartest mathematicians hired by the U.S. government to solve the most elusive problem in computer science history — P vs. NP. The four have jointly created a "system" which could be the next major advancement for humanity or the downfall of society."
You can begin to see that there is scope for some drama, but rather than explain in any more detail it is better to just watch the trailer.


Submission + - Scientists Clone Sheep With 'Good' Fat (

redletterdave writes: "Chinese scientists have cloned a genetically modified sheep containing a "good" type of fat found naturally in nuts, seeds, fish and leafy greens that helps reduce the risk of heart attacks and cardiovascular disease. The gene, which is linked to the production of polyunsaturated fatty acids, was inserted into a donor cell taken from the ear of a Chinese Merino sheep. The cell was then inserted into an unfertilized egg and implanted into the womb of a surrogate sheep. With any luck, this process could be replicated in the future to clone more animals for safe and healthy consumption."

Submission + - FBI to disconnect Internet users (

R3d Jack writes: Not really, but that's what another software engineer was telling me today. If people did not go to a U.S. government sponsered Web site and have their computers scanned, the FBI would "disconnect" them in July. The article tells the whole story, but the FBI actually is helping ordinary people out for once by replacing servers run by scammers with legitimate ones, at least temporarily. The G-Men realized that all the victims (500,000 plus) would lose DNS service if they just yanked the rogue servers. The Feds also teamed up with a private company that will scan your PC for the infection and provide information on how to remediate it. I think I'll pass on the scan, thank you...

Submission + - Private company announces serious plan to mine asteroids in the next few years (

The Bad Astronomer writes: "The private company Planetary Resources has announced that it plans to mine asteroids for water, air, and even precious metals in the next few years. Your initial reaction may be to snicker a bit, but it's headed by Peter Diamandis — who established the X Prize — has several ex-NASA personnel running the engineering, and also has the backing of a half-dozen or so billionaires. So this is no joke — their plan looks solid, and may very well be the first step in establishing a permanent human presence in space."

Submission + - NIH Director Supports Release of Bird Flu Research (

renek writes: Common Sense has struck again as the director for the National Institute of Health has called for the release of two studies about the deadly H5N1 avian flu virus. The U.S. Government had previously advised that the research not be published in the journals Science and Nature. From the article,

"On March 29 and 30, the National Science Advisory Board for Biosecurity (NSABB), an independent expert committee that advises the National Institutes of Health (NIH), the Department of Health and Human Services (HHS) and other Federal departments and agencies on matters of biosecurity, convened to review unpublished revised manuscripts describing NIH-funded research on the transmissibility of H5N1 influenza virus—the strain commonly referred to as "bird flu"
During its March meeting, the NSABB took into account the new and clarified information in the manuscripts, additional perspectives provided by influenza biology experts, highly pertinent but as yet unpublished epidemiologic data, and relevant security information. After careful deliberation, the NSABB unanimously recommended the revised manuscript by Dr. Yoshihiro Kawaoka be communicated in full.

Previously, he’s built things such as a laser-sighted wrist-mounted crossbow, and a hand-mounted flamethrower. His latest creation, the Blade Driver, is a full-size laser-sighted crossbow ... oh yeah, and instead of shooting arrows, it shoots spinning rotary saw blades.

Submission + - HARVARD suggests move to open-access journals. ( 1

microcars writes: Harvard has a announced to faculty: "We write to communicate an untenable situation facing the Harvard Library. Many large journal publishers have made the scholarly communication environment fiscally unsustainable and academically restrictive. This situation is exacerbated by efforts of certain publishers (called “providers”) to acquire, bundle, and increase the pricing on journals."
The memo goes on to describe the situation in more detail and suggests options to faculty and students for the future that includes submitting articles to open-access journals. If Harvard paves the way with this, how long until other academic bodies follow suit and cut off companies such as Elsevier?
