TurboTax Went Down At a Kind of Crucial Moment and Didn’t Handle It Well on Twitter
NASA has spent a lot of time and money resurrecting the F-1 rocket engine that powered the Saturn V back in the 1960s and 1970s, and Ars recently spent a week at the Marshall Space Flight Center in Huntsville, Alabama, to get the inside scoop on how the effort came to be . But there’s a very practical reason why NASA is putting old rocket parts up on a test stand and firing them off: its latest launch vehicle might be powered by engines that look, sound, and work a whole lot like the legendary F-1. This new launch vehicle, known as the Space Launch System , or SLS, is currently taking shape on NASA drawing boards. However, as is its mandate, NASA won’t be building the rocket itself—it will allow private industry to bid for the rights to build various components. One potential design wrinkle in SLS is that instead of using Space Shuttle-style solid rocket boosters, SLS could instead use liquid-fueled rocket motors, which would make it the United States’ first human-rated rocket in more than 30 years not to use solid-fuel boosters. The contest to suss this out is the Advanced Booster Competition , and one of the companies that has been down-selected as a final competitor is Huntsville-based Dynetics . Dynetics has partnered with Pratt Whitney Rocketdyne (designers of the Saturn V’s F-1 engine, among others) to propose a liquid-fueled booster featuring an engine based heavily on the design of the famous F-1. The booster is tentatively named Pyrios , after one of the fiery horses that pulled the god Apollo’s chariot; the engine is being called the F-1B. Read 34 remaining paragraphs | Comments

With all the stories about “de-extinction” of animal species lately, there’s one method that doesn’t get much notice -when scientists decide that an extinct species never existed in the first place. That applies to the case of Pelusios seychellensis , which, according to specimens collected by German naturalist August Brauer over 100 years ago, lived in the Seychelles off the east coast of Africa. Curiously, these turtles closely resembled turtles on the west coast of Africa, Pelusios castaneus . But they couldn’t be the same, because they lived so far apart. So the separate species name was coined in 1983. But even more curious, no one could find any specimens of Pelusios seychellensis in the Seychelles, and scientists concluded that the species had gone extinct during the 20th century. Not only that, they assumed that humans had caused the extinction. But wait… Brauer took the trip during which he was supposed to have collected the turtles between May 1895 to January 1896. But he didn’t immediately give his finds to a museum. Specimens from his private collection didn’t get transferred to the Zoological Museum Hamburg until five years after the Seychelles trip, and those turtles soon went on to Vienna’s Natural History Museum. Somewhere in all that shuffling, the west African turtles might have been lumped in with the Seychelles reptiles or otherwise confused. Whatever happened, though, a prominent clue indicates that the turtles were not collected from the wild. One, and possibly two, of the turtles have a perforation through their shells identical to the sort that turtle purveyors have traditionally used to tie turtles together until they are sold for food. Wherever Brauer got the turtles from, he seems to have purchased them. Oops. On the bright side, this means that humans did not cause the extinction of a turtle species, because Pelusios castaneus is still around -on Africa’s west coast.

If you’re building an HTPC, a small workstation, or you just don’t want your rig to take up tons of space under or on top of your desk, you need a smaller PC case. Something that fits the important stuff, but doesn’t waste a lot of space on expansion bays or components you may not need. This week we’re going to take a look at five of the best for the job.

Five Best Small Form Factor PC Cases
It’s well off the triple year-over-year growth that e-books saw a few years ago , but the latest report from the Association of American Publishers shows that e-books did inch up even further in 2012 to account for a sizeable chunk of overall book sales. According to its figures, e-books now represent 22.55 percent of US publishers’ total revenue — up from just under 17 percent in 2011 — an increase that helped push net revenue from all book sales up 6.2 percent to $7.1 billion for the year. As the AAP notes, this report also happens to mark the tenth anniversary of its annual tracking of e-book sales; back at the beginning in 2002, their share of publishers’ net revenue clocked in at a mere 0.05 percent. The group does caution that the year-to-year comparison back that far is somewhat anecdotal, however, given changing methodologies and definitions of e-books. Comments Via: The Next Web Source: AAP

CloudFlare Security analysts have detected an ongoing attack that uses a huge number of computers from across the Internet to commandeer servers that run the WordPress blogging application. The unknown people behind the highly distributed attack are using more than 90,000 IP addresses to brute-force crack administrative credentials of vulnerable WordPress systems, researchers from at least three Web hosting services reported. At least one company warned that the attackers may be in the process of building a “botnet” of infected computers that’s vastly stronger and more destructive than those available today. That’s because the servers have bandwidth connections that that are typically tens, hundreds, or even thousands of times faster than botnets made of infected machines in homes and small businesses. “These larger machines can cause much more damage in DDoS [distributed denial-of-service] attacks because the servers have large network connections and are capable of generating significant amounts of traffic,” Matthew Prince, CEO of content delivery network CloudFlare, wrote in a blog post describing the attacks.

Microsoft has pulled a Windows 7 security update released as part of this month’s Patch Tuesday after discovering it caused some machines to become unbootable. Update 2823324 , which was included in the MS13-036 bulletin , fixed a “moderate-level vulnerability” that requires an attacker to have physical computer access to be able to exploit a targeted computer, Dustin Childs, a group manager in the Microsoft Trustworthy Computing group, wrote in a blog post published Thursday evening. The company has now pulled it from the bulletin and is advising at least some Windows users who have installed it to uninstall the update following the guidance here . MS130-26 was one of nine bulletins released on Monday to fix 13 separate vulnerabilities. “We’ve determined that the update, when paired with certain third-party software, can cause system errors,” Childs wrote. “As a precaution, we stopped pushing 2823324 as an update when we began investigating the error reports, and have since removed it from the download center.” Read 3 remaining paragraphs | Comments

Yesterday, brokerage firm Detwiler Fenton claimed that more people were returning BlackBerry Z10s than had bought them at retail in the first place. Today, BlackBerry responded , saying not only that the Detwiler report was incorrect, but that it was going to ask the Securities and Exchange Commission in the US and the Ontario Securities Commission in Canada to review the report. Of the reports, BlackBerry CEO Thorsten Heins said, “Return rate statistics show that we are at or below our forecasts and right in line with the industry. To suggest otherwise is either a gross misreading of the data or a willful manipulation. Such a conclusion is absolutely without basis and BlackBerry will not leave it unchallenged.” The smartphone company also noted that Detwiler refused to make its report or methodology available. How more phones could be returned than were sold isn’t clear. Detwiler Fenton is the same firm that predicted that Microsoft would sell 2-3 million Surface Pro units in the fourth quarter of 2012, despite the fact that Microsoft explicitly said the device wouldn’t ship until three months after the Surface RT’s October launch.

Watch this CDC map change from 1985 to 2010 -and get more colorful along the way. It shows the percentage of people medically defined as obese. Obesity was once an odd condition, but for the U.S. it just gets more common every year. The Atlantic has a list of the metropolitan areas that have the lowest and highest rates of obesity. Moving to Colorado will only help if you are willing to climb mountains, hike, and ski. Link
