The Best Near-Term Future of Space Exploration?

August 30th, 2010 08:13 admin View Comments

An anonymous reader writes “Much fanfare has been made about manned missions to moons and planets, but little has been done about travel to the asteroids — until now. NASA is working on plans for a trip to the asteroids by 2025. This type of mission has great potential for positive economic return based on the fact that no effort has to be spent on getting in and out of a distant planet’s gravity well. Yes, we should go to the planets, but we should master mining the asteroid belt for resources first because it is easiest. What do you think?”

CTRC Orders Big ISPs To Provide Matching Speeds For Resellers

August 30th, 2010 08:34 admin View Comments

Meshach writes “In Canada there has been a regulatory decision rendered by the CRTC ordering ISPs to provide the same speed to resellers as they do for their own customers. ‘Smaller internet providers such as Teksavvy and Execulink had argued that without requirements to offer matching speeds, the big companies would put them out of business. Bell and Telus are selling internet connections of up to 25 and 15 megabits per second respectively over newer fibre-based networks, but smaller providers can typically offer speeds of no more than five megabits per second over older copper-based infrastructure. After holding a public hearing earlier this year, the CRTC now says it will allow phone companies to charge smaller providers an extra 10-per-cent mark-up to use their newer infrastructure in order to recoup the costs of their investments. The regulator also said it would require cable companies to modify their existing internet access services to make it easier for smaller, “alternative” providers to connect to them.’”

Judge Quashes Subpoena of UVA Research Records

August 30th, 2010 08:43 admin View Comments

esocid writes “An Albemarle County Circuit Court judge has set aside a subpoena issued by Virginia Attorney General Ken Cuccinelli to the University of Virginia seeking documents related to the work of climate scientist and former university professor Michael Mann. Judge Paul M. Peatross Jr. ruled that Cuccinelli can investigate whether fraud has occurred in university grants, as the attorney general had contended, but ruled that Cuccinelli’s subpoena failed to state a ‘reason to believe’ that Mann had committed fraud. He also set aside the subpoena without prejudice, meaning Cuccinelli can rewrite it to better explain why he wants to investigate, but seemed skeptical about the underlying claim of fraud. The ruling is a major blow for Cuccinelli, a global warming skeptic who had maintained he was investigating whether Mann committed fraud in seeking government money for research that showed the earth has experienced a rapid, recent warming. Mann, now at Penn State University, worked at U-Va. until 2005. ‘The Court has read with care those pages and understands the controversy regarding Dr. Mann’s work on the issue of global warming. However, it is not clear what he did was misleading, false or fraudulent in obtaining funds from the Commonwealth of Virginia,’ Peatross wrote. The ruling also limited Cuccinelli to asking about only one of the five grants issued, which was the only one using state funds.”

August 30th, 2010 08:04 admin View Comments

Hotmail ActiveSync

Microsoft has finally announced that starting today Hotmail will support push email, calendar and contacts with Exchange ActiveSync (EAS).

Hotmail users will be able to sync their email, calendar, and contacts to their iPhone using Exchange ActiveSync. So any changes made on the iPhone will be reflected on the web interface, and vice versa.

This is great news if you use Hotmail as Dick Craddock from Windows Live blog explains:

Hotmail is making it easier for you to stay up-to-date and be productive on your phone. Starting today, you can get your email, calendar, and contacts pushed automatically to your phone using Exchange ActiveSync (EAS). EAS keeps everything in sync between your phone and Hotmail, so whatever you do on your phone, like delete an email, add an appointment, or update one of your contacts with a new number, will also be reflected on the web, and vice-versa. If you use an email client on your PC that already syncs with Hotmail, like Outlook with the Outlook Connector or Windows Live Mail, what you do on your phone will show up there as well, delivering a seamless experience for managing your stuff between your PC email client, your browser, and your phone.

You can follow these steps to setup Hotmail using Exchange ActiveSync on your iPhone, iPad and iPod Touch:

  1. Launch the Settings App. Under Settings, tap on “Mail, Contacts, Calendar”.

  2. Then tap on “Add Account”.

  3. Tap on “Microsoft Exchange” to configure Hotmail ActiveSync.

    Hotmail ActiveSync

  4. Enter your full Hotmail email address in both Email and Username fields. Leave Domain blank. Enter your password. In the Description field, enter a name, e.g Hotmail.

    Hotmail ActiveSync

  5. Then tap on the Next button.

  6. After the details entered above are successfully verified. You will get another screen where you need to enter m.hotmail.com for the Server name. Then tap on the Next button.

    Hotmail ActiveSync

  7. If the verification is successful, you will see this screen. Select the data (Mail, Contacts, Calendar) to sync and then tap on Save.

    Hotmail ActiveSync

That’s it, you’re all set for push email, calendar and contacts for your Hotmail account.

Burning Man Goes Open Source For Cell Phones

August 30th, 2010 08:50 admin View Comments

coondoggie passes along this excerpt from Network World:
“Today I bring you a story that has it all: a solar-powered, low-cost, open source cellular network that’s revolutionizing coverage in underprivileged and off-grid spots. It uses VoIP yet works with existing cell phones. It has pedigreed founders. Best of all, it is part of the sex, drugs and art collectively known as Burning Man. … The technology starts with the ‘they-said-it-couldn’t-be-done’ open source software, OpenBTS. OpenBTS is built on Linux and distributed via the AGPLv3 license. When used with a software-defined radio such as the Universal Software Radio Peripheral (USRP), it presents a GSM air interface (“Um”) to any standard GSM cell phone, with no modification whatsoever required of the phone. It uses open source Asterisk VoIP software as the PBX to connect calls, though it can be used with other soft switches, too. … This is the third year its founders have decided to trial-by-fire the system by offering free cell phone service to the 50,000-ish attendees at Burning Man, which begins today in Black Rock City, Nevada. “

Can Endangered Bluefin Tuna Be Saved by Fish Farming?

August 30th, 2010 08:43 admin View Comments

bluefinBluefin tuna–they’re so delicious, they’re on the brink of extinction. The human appetite for this majestic fish has spurred overfishing that has endangered the wild population, so researchers and aquaculture companies are trying to breed the fish in captivity. But so far bluefin tuna have proved very difficult to farm, since it’s impossible to replicate their natural reproductive cycle–researchers think the fish travel hundreds of miles to their traditional spawning grounds. The best results so far have come from an Australian company that is using hormone injections to get the big fish to breed.

Now researchers associated with a European project called Selfdott (an odd acronym for “self-sustained aquaculture and domestication of thunnus thynnus”) say they can successfully raise fish in captivity without using hormones. The New York Times reports that the first batch of fish, raised in floating cages, died after a matter of weeks or months, but researchers still think that with better food and parents more adjusted to captivity, the next group of fish will survive.

“If the results of this research can ultimately be commercialized, it can improve food supplies and contribute to economic growth and employment while also helping to ensure a sustainable management of bluefin tuna,” Máire Geoghegan-Quinn, the European Union’s commissioner for research, said this week. [New York Times]

Because the predator fish are high on the food chain, requiring lots of food (in the form of smaller fish) and many years to grow, environmentalists still aren’t too keen on the aquaculture fix.

Tuna is one of the most environmentally punishing fish to farm, in part because the fish takes a decade or more to mature. During this time, the captive fish are fed massive amounts of smaller wild fish–an estimated 20 tons of food fish goes into each ton of tuna produced–so those prey species may become depleted in turn. The farms also produce high concentrations of fish waste, polluting the area around the farm, and can be breeding grounds for piscine diseases and parasites like sea lice. [Popular Science]

It would be better, some say, to eat fish lower on the food chain that require less resources. Saskia Richartz, an oceans and fisheries expert with the European unit of Greenpeace told The New York Times:

“[T]his is tantamount to breeding elephants in captivity for their ivory.” [The New York Times]
