Today’s SpaceX launch will see the first attempt at landing its booster

Source: Arstechnica


The latest SpaceX resupply mission to the International Space Station is set to lift off at 6pm US Eastern Time today. The Falcon 9 launch vehicle will be sending a Dragon capsule into orbit to bring over 5,000 lbs of supplies and science experiments to the ISS. If all goes according to plan, the Dragon will rendezvous with the Station early Wednesday morning (also US Eastern).

This is SpaceX's third resupply mission, so parts of the liftoff and rendezvous are likely to be routine. Lately, however, SpaceX has been doing interesting things with its Falcon boosters after payload separation. Back in September, the Falcon flipped around in flight and fired its engines to reverse direction, the first step toward a controlled return to the atmosphere.

This time around, the company is planning on expanding on that test. "During today’s launch SpaceX will attempt to recover the first stage of the Falcon 9 launch vehicle as part of SpaceX’s reusability program," a SpaceX spokesperson told Ars. "It’s important to note this is not a primary mission objective and the probability of recovering the first stage is low, maybe 30-40 percent."

The attempt will see the Falcon repeat the flip-and-burn that slows it for reentry and then ignite a single engine to slow it during its descent. During this burn, the legs that may eventually allow it to land safely will be deployed to test their effect on the aerodynamics of the descent. In this case, the Falcon will land in the water, so the legs won't be involved in an actual touchdown. The long-term goal, however, is to land Falcons on land and send them back to space multiple times, a process that should greatly reduce launch costs.

Mike Huckabee, Asshole of the Day for April 13, 2014


For the last 5 years there has been a neverending pattern of conservatives clutching their pearls and crying tyranny. Often it can be something like spying on American citizens and they cry out that Obama has destroyed American freedom, even though, as in the case of Sean Hannity, the program started under Bush and Hannity was a very vocal supporter of the program under Bush.

But invocations of tyranny are usually limited to past tyrants like Stalin or Hitler, not current ones. And for good reason— current tyrants still continue to do horrible things that would make the speaker look ridiculous. Apparently Mike Huckabee hasn’t figured this part out though, since he’s now on record comparing the US to North Korea:

"I’m beginning to think theres more freedom in North Korea sometimes than there is in the United States."

The context for this quote is from going to the airport and having to deal with the TSA security. Here’s more:

“When I go to the airport, I have to get in the surrender position, people put hands all over me, and I have to provide photo ID and a couple of different forms and prove that I really am not going to terrorize the airplane – but if I want to go vote I don’t need a thing,” he continued, according to MSNBC.


The 'culture of shut up' is sometimes just rude people who disagree

Last week, I made a shocking discovery: some leftwing activists have developed a sinister new superpower that enables them to control other people’s actions by brainwaves alone. Their first victim was Brendan Eich, appointed then un-appointed as head of Mozilla, after his financial support for the campaign against gay marriage (and in support of Pat Buchanan) came to light. To outsiders like me, it seemed as if a high-profile firm had made a decision about its leadership; that its employees and users had engaged in vigorous debate about that decision; and that the company had decided to reverse it.

But it turned out that opponents of Eich’s new role hadn’t just been voicing their opinions. Somehow, by means I’ve yet to understand, they’d forced him to resign. That was the phrase used again and again, including in a piece entitled The Culture of Shut Up, by the former Obama speechwriter Jon Lovett, with which the internet declared itself richly pleased. “We need to stop telling each other to shut up. We need to get comfortable with the reality that no one is going to shut up,” Lovett wrote, correctly. But he didn’t mean that Eich’s raucous critics should be tolerated. He meant that the Culture of Shut Up had silenced Eich, by forcing him to resign. And not just Eich. Lovett listed many more victims, including celebrity chef-and-alleged-racist Paula Deen and Phil Robertson of Duck Dynasty, who, I’m told, is a man on a television show who is cross about gays.

And all that happened before Brandeis University bunglingly offered then withdrew an honorary degree for Ayaan Hirsi Ali.

Oh, man.


If the answer is not obvious then we are all in big trouble ...



MH370: Is it time to stop searching for pings?

Source: CNN

Kuala Lumpur, Malaysia (CNN) -- Is it time for underwater search vehicles to start scanning the ocean floor in the hunt for Malaysia Airlines Flight 370?

Some analysts say it is, because it's been days since anyone has picked up a possible signal from the missing aircraft's data recorders.

And the batteries powering the locator beacons inside the so-called black boxes are probably dead, a top official from the company that manufactures the beacons told CNN on Sunday. That means searchers may not be able to detect any more pings to help lead them to those pieces of the missing plane.

Meanwhile, the search area for Malaysia Airlines Flight 370 grew over the weekend. And authorities say no one onboard the plane has been ruled out in connection with its disappearance.

Official says sub will be used in search for jet

PERTH, Australia — Search crews will for the first time send a sub deep into the Indian Ocean to try and determine whether signals detected by sound-locating equipment are from the missing Malaysian plane’s black boxes.

Angus Houston, the head of a joint agency coordinating the search off Australia’s west coast, said Monday that the crew on board the Ocean Shield will launch the underwater vehicle as soon as possible. The Bluefin 21 autonomous sub can create a sonar map of the area to chart any debris on the seafloor.

The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft’s black boxes.


Submersible to search for MH370

Teams searching for the missing Malaysia Airlines plane are to deploy a submersible for the first time.

Search chief Angus Houston said work using the towed pinger locator would stop, with the Bluefin 21 submersible drone sent down as soon as possible.

He said no new acoustic signals thought to be from the missing plane had been detected since 8 April.

Air Chief Marshall Houston warned that the submersible search would be a long process that could yield no results.



PERTH, Australia (AP) — Search crews will send a sub deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said.

Angus Houston said the crew on board the Ocean Shield will launch the underwater vehicle sometime Monday evening. The Bluefin 21 autonomous sub can create a sonar map of the area to chart any debris on the seafloor.

The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes.

"We haven't had a single detection in six days, and I guess it's time to go under water," said Houston, the head of a joint agency coordinating the search off Australia's west coast.


Searchers Will Deploy Sub in Search for Malaysia Jet Wreckage

Investigators scouring for the missing Malaysia Airlines jet will send a submarine deep into the Indian Ocean for the first time to try and figure out whether signals picked up by sound-locating equipment are from Flight 370's black boxes, taking the hunt underwater after six weeks of searching.

The crew aboard the Australian Navy vessel Ocean Shield will launch the Bluefin 21 autonomous underwater vehicle as soon as possible, said Angus Houston, the head of a joint agency coordinating the painstaking search off Australia's west coast, at a news conference just after 12 p.m. local time (12 a.m. ET).


MH370 search to shift focus to underwater scan

Australian authorities will deploy an underwater vehicle on Monday evening to continue the search for the missing Malaysia Airlines plane, as it is now believed unlikely there will be any further sonar detections of the black boxes.

The search for the missing plane, which is believed to have crashed in the Indian Ocean, claiming the lives of all 239 passengers on board, will enter a new phase now on the 38th day since the plane went missing, involving an underwater search vessel known as “Blue Fin 21” that will be deployed from the Australian defence vessel Ocean Shield.

The vehicle is sent out on 24-hour search cycles, and will spend four hours on the Ocean Shield after each search, having its batteries charged and allowing the data to be downloaded and analysed. Private contractors for the US navy from Phoenix International will analyse the data onboard the Ocean Shield.

The head of Australia’s joint co-ordination centre, Angus Houston, said on Monday: “We haven’t had a single detection in six days so it’s time to go underwater … The deployment of the underwater autonomous vehicle allows us to take a step forward.”


Nevada ranching family claims victory as government releases cattle

Source: Reuters

(Reuters) - U.S. officials ended a stand-off with hundreds of armed protesters in the Nevada desert on Saturday, calling off the government's roundup of cattle it said were illegally grazing on federal land and giving about 300 animals back to the rancher who owned them.

The dispute less than 80 miles northeast of Las Vegas between rancher Cliven Bundy and the U.S. Bureau of Land Management had simmered for days. Bundy had stopped paying fees for grazing his cattle on the government land and officials said he had ignored court orders.

Anti-government groups, right-wing politicians and gun-rights activists camped around Bundy's ranch to support him in a standoff that tapped into long-simmering anger in Nevada and other Western states, where vast tracts of land are owned and governed by federal agencies.

The bureau had called in a team of armed rangers to Nevada to seize the 1,000 head of cattle on Saturday but backed down in the interests of safety.

Everything You Need to Know About High-Frequency Trading

The stock market isn't rigged, but it is taxed.

It always has been. As Justin Fox points out, for as long as people have been trading stocks, there have been middlemen taking a cut of the action. Now, that cut has gotten smaller as markets have gotten bigger and more technologically-advanced, but it's still there. It's the implicit fee that intermediaries charge for making sure there's a buyer for every seller, and a seller for every buyer—for "making markets."

But there's a new kind of middleman today. They don't work at stock exchanges or banks. They work at hedge funds, and trade at whiz-bang speeds. These "high-frequency traders" (HFT) use computer algorithms—a.k.a., algobots—to arbitrage away the most infinitesimal price discrepancies that only exist over the most infinitesimal time horizons. You can see just how small and how fast we're talking about in the chart below from a new paper by Eric Budish and John Shim of the University of Chicago and Peter Cramton of the University of Maryland. It uses 2011 data to show the price difference between futures (blue) and exchange-traded funds (green) that both track the S&P 500. These should be perfectly correlated, and they are—at minute intervals. But this correlation disappears at 250 millisecond intervals, a little more than half the time it takes to blink your eyes. This is the "inefficiency" that HFT makes less so.


Wait -- Drugmakers like Pfizer and Johnson and Johnson ....


Does the Heartbleed Bug Mean You Should Stay Off the Internet?

Update: The NSA knew about the Heartbleed bug for at least two years and actively exploited it in order to gather intelligence, Bloomberg reported on Friday. This means that under the pretense of protecting Americans, the NSA intentionally didn't notify millions of Americans that they were vulnerable to identity theft. Go read that book, now.

On Tuesday, news broke that the safeguard many websites use to protect sensitive information on the internet has had a major security flaw for about two years. These sites use a security system called OpenSSL to encrypt data like content, passwords, and Social Security numbers. But thanks to a small coding error in a popular version of OpenSSL, nicknamed "Heartbleed," hackers can potentially steal sensitive data from vulnerable websites. Richard Bejtlich, chief security strategist at FireEye, a network security company, notes that there's no evidence that malicious hackers have exploited the flaw yet. But the secrecy-minded Tor Project, which enables anonymous internet browsing, nevertheless recommended on Monday that, "If you need strong anonymity or privacy on the internet, you might want to stay away from the internet entirely for the next few days while things settle." Here are seven reasons why you might want to stop looking at cat videos right now:

1. Lots of popular websites have the security problem.

According to the New York Times, up to two-thirds of sites on the internet rely on OpenSSL. A user on Github, an open-source coding site, compiled a list of sites that were allegedly vulnerable after a test was conducted on Tuesday. The Github list included Yahoo, Flickr, OkCupid, and Eventbrite, among dozens of other companies. (Some may have since updated their security.) Facebook and Google both released statements confirming they are not affected by the flaw. If you'd like to test a specific site to see whether it's could be exploited—although this doesn't meant that it has—go here.
