New F-1B rocket engine upgrades Apollo-era design with 1.8M lbs of thrust

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

A beginner’s guide to building botnets—with little assembly required

Original photo by Michael Kappel / Remixed by Aurich Lawson Have a plan to steal millions from banks and their customers but can’t write a line of code? Want to get rich quick off advertising click fraud but “quick” doesn’t include time to learn how to do it? No problem. Everything you need to start a life of cybercrime is just a few clicks (and many more dollars) away. Building successful malware is an expensive business. It involves putting together teams of developers, coordinating an army of fraudsters to convert ill-gotten gains to hard currency without pointing a digital arrow right back to you. So the biggest names in financial botnets—Zeus, Carberp, Citadel, and SpyEye, to name a few—have all at one point or another decided to shift gears from fraud rings to crimeware vendors, selling their wares to whoever can afford them. In the process, these big botnet platforms have created a whole ecosystem of software and services in an underground market catering to criminals without the skills to build it themselves. As a result, the tools and techniques used by last years’ big professional bank fraud operations, such as the ” Operation High Roller ” botnet that netted over $70 million last summer, are available off-the-shelf on the Internet. They even come with full technical support to help you get up and running. Read 63 remaining paragraphs | Comments

BitCoin Value Collapses, Possibly Due To DDoS

hydrofix writes “The Bitcoin-to-USD exchange rate had been climbing steadily since January 2013, from around 30 USD to over 250 USD only 24 hours ago. Now, the value bubble seems to have burst, at least partially. The primary trading site MtGox reported a drop in value all the way down to 140 USD today, a loss of almost half in real value. With many sites unreachable or slow, there are also news of a possible DDoS attack on MtGox: ‘Attackers wait until the price of Bitcoins reaches a certain value, sell, destabilize the exchange, wait for everybody to panic-sell their Bitcoins, wait for the price to drop to a certain amount, then stop the attack and start buying as much as they can. Repeat this two or three times like we saw over the past few days and they profit.'” Read more of this story at Slashdot.

OS X 10.8.4 beta suggests 802.11ac is coming soon to a Mac near you

Amid the sea of text, a revealing phrase: 802.11ac. 9to5Mac Before rolling them out to the public through Software Update, Apple regularly releases beta versions of its minor OS X updates to registered developers and other selected testers. These patches are normally routine—a security patch here, a new driver there—but they occasionally reveal tidbits about where Apple is taking OS X and, by extension, its Mac lineup. A new build of OS X 10.8.4 was released to beta testers today, and 9to5Mac cracked it open in short order. Hidden in the operating system’s “WiFi-frameworks” folder is a brand-new reference to 802.11ac Wi-Fi , a new standard that promises bandwidth of up to 1.3Gbps. The fastest Wi-Fi chips in today’s Macs support 802.11n at speeds of either 450Mbps (for devices with three antennae like the iMac or MacBook Pro) or 270Mbps (for devices like the MacBook Air with only two antennae), making the new standard quite the potential upgrade. As with previous Wi-Fi upgrades, the new 802.11ac adapters and routers will also be backward-compatible with 802.11n, g, b, and a-based devices. Routers and adapters that support 802.11ac first began to appear on the market last year, and have slowly proliferated as the months have gone on. We saw quite a few 802.11ac routers at this year’s CES , and 802.11ac chips from the likes of Broadcom should begin to show up in many consumer devices this year. Even some smartphones (the HTC One in particular) are beginning to ship with the new standard, so it wouldn’t be a surprise if Apple made the jump in this year’s Macs.

Intel wants to kill the traditional server rack with 100Gbps links

If Intel gets its way, old-school server racks will go the way of the dinosaurs. David Monniaux Intel is working to replace the traditional server rack with a more efficient architecture that separates CPU, storage, power, and networking resources into individual components that can be swapped out as needed. Power and cooling would be shared across CPUs, rather than having separate power supplies for each server. Server, memory, network, and storage resources would all be disaggregated and shared across the rack. Incredibly fast interconnects will be needed to prevent slowdowns because disaggregating components pushes them further apart, and Intel is thus building an interconnect that’s capable of 100Gbps. “We are developing a rack-scale architecture,” Lisa Graff, VP and general manager of Intel’s data center marketing group, said in a briefing with reporters last week. “We’re working with end users, OEMs, and ISVs to drive common standards in a reference architecture.” Read 18 remaining paragraphs | Comments

Waiting for a 1TB SSD below $1 per GB? Crucial says wait no more

Crucial announced in a press release this morning that it has begun selling its latest round of consumer-grade solid-state disks (SSDs), the M500 . The 2.5-inch SATA III SSDs are the follow-up to Crucial’s M4 SSDs, which are a pretty popular choice for people adding SSDs to existing systems (I think I have four or five M4s scattered in computers around my house). The drives use 20nm MLC NAND sourced from Micron (and if you’re not sure what MLC NAND is, we’ve got a great SSD primer right here ), along with a Micron-provided SSD controller. Performance for the M500 drives is what you’d expect from a drive in this class: sequential read and write speeds of 500MB per second and 400MB per second. But the big news about the announcement is the capacities. The M500 is available in standard pedestrian capacities of 120GB and 240GB, as well as a large capacity of 480GB, but the top-end SKU is the exciting one: 960GB for just $599.99 (62¢ per raw GB). The MSRPs for the smaller capacities are $129.99 for the 120GB (about $1 per raw GB), $219.99 for the 240GB (about 91¢ per raw GB), and $399.99 for the 480GB (about 83¢ per raw GB).

Apple says VPN changes coming in iOS thanks to VirnetX verdict

Apple has been forced to change how iOS devices use VPN following a $368.2 million patent verdict in favor of patent and research firm VirnetX. The company wrote about the changes in a support document posted to its website on Thursday (hat tip to AppleInsider ), saying the behavior of VPN On Demand would be different from expected starting with iOS 6.1, and the changes would come in an update that will be released this April. “Due to a lawsuit by VirnetX, Apple will be changing the behavior of VPN On Demand for iOS devices using iOS 6.1 and later,” Apple wrote. “This change will be distributed in an update later this month.” The changes are relatively minor—devices with VPN On Demand configured to “always” will instead behave as if they’re set up to “establish [a connection] if needed.” Apple says the device in question will then only establish a new VPN On Demand connection if it’s not able to resolve the DNS of the host it wants to reach (these settings can currently be found within Settings > General > VPN).

Report: Xbox 360 successor can tolerate only brief Internet interruptions

Kotaku is citing two unnamed sources that it says “have a perfect track record in getting these kinds of things right” to report that Microsoft’s follow-up to the Xbox 360 will need a working Internet connection to start games and apps. And the site goes on to write that the system will only tolerate brief interruptions in that connection while the game or app is being used. “Unless something has changed recently, Durango consumer units must have an active Internet connection to be used,” one source told the site, referring to the internal code name for Microsoft’s next system. “If there isn’t a connection, no games or apps can be started. If the connection is interrupted, then after a period of time—currently three minutes, if I remember correctly—the game/app is suspended and the network troubleshooter started.” Another source said this requirement was still in effect on development hardware as recently as two weeks ago. Information suggesting that the next Microsoft console will need to be online is nothing new; numerous leaks and rumors have pointed in that direction throughout the last year or so. However, this is the first serious suggestion that such connectivity would need to be more or less continuous while a game is being played, rather than just checked once when a game or app is launched.

Frustrated with iCloud, Apple’s developer community speaks up en masse

Aurich Lawson Apple’s iCloud is marketed to us end users as a convenient and centralized way to manage data on all of our Macs and iOS devices: sync contacts and bookmarks, re-download music and apps, back up iOS devices, and sync documents and data for third-party apps as MobileMe did. The last item, syncing of documents and data, is one of the least glossy features of iCloud, but it is one of the most important, and it should be among the most straightforward. Right? Perhaps not. Almost a year after Apple shut down MobileMe for good in favor of iCloud , third-party developers have begun to speak out about the difficulty involved in working with Apple’s cloud service. A piece published at The Verge this week highlights many of those complaints, with quotes coming from well-known developers and anonymous sources alike about the challenges faced by the developer community. From data loss and corruption to unexpected Apple ID use cases, developers have seen it all—but are stymied by the persistence of problems that prevent them from shipping products with working iCloud support. What’s the big problem, exactly? According to Bare Bones Software’s Rich Siegel, there are a number of moving parts to iCloud that all affect how things come out on the other end.

How the maker of TurboTax fought free, simple tax filing

This story was co-produced with NPR . Imagine filing your income taxes in five minutes—and for free. You’d open up a prefilled return, see what the government thinks you owe, make any needed changes and be done. The miserable annual IRS shuffle, gone. It’s already a reality in Denmark, Sweden, and Spain . The government-prepared return would estimate your taxes using information your employer and bank already send it. Advocates say tens of millions of taxpayers could use such a system each year, saving them a collective $2 billion and 225 million hours in prep costs and time, according to one estimate.
