sciencehabit writes "Last year, Jeffrey Aristoff and Howard Stone, mechanical engineers at Princeton University, were at the gym waiting for a pickup game of basketball. To warm up, Stone started jumping rope. As the rope whizzed over the head of his colleague, Aristoff wondered, 'Is it known how jump ropes bend in the wind?' A few literature searches later, he concluded that the answer was, 'not really.' Now, the two have solved the problem themselves."

sammcj writes with news that HP is developing servers based on 32-bit ARM processors from Calxeda. Their current model is only a test setup, but they plan to roll out a finalized design by the middle of next year. "HP's server design packs 288 Calxeda chips into a 4U rack-mount server, or 2,800 in a full rack, with a shared power, cooling, and management infrastructure. By eliminating much of the cabling and switching devices used in traditional servers and using the low-power ARM processors, HP says it can reduce both power and space requirements dramatically. The Redstone platform uses a 4U (7-inch) rack-mount server chassis. Inside, HP has put 72 small server boards, each with four Calxeda processors, 4GB of RAM and 4MB of L2 cache. Each processor, based on the ARM Cortex-A9 design, runs at 1.4GHz and has its own 80 gigabit cross-bar switch built into the chip"

sciencehabit writes "Some sounds are excruciating. Take fingernails squeaking on a chalkboard. The noise makes many people shudder, but researchers never knew exactly why. A new study finds that there are two factors at work: the knowledge of where the sound is coming from and the unfortunate design of our ear canals. 'The offending frequencies were in the range of 2000 to 4000 Hz. Removing those made the sounds much easier to listen to. Deleting the tonal parts of the sound entirely also made listeners perceive the sound as more pleasant, whereas removing other frequencies or the noisy, scraping parts of the sound made little difference.'"

First time accepted submitter AtomicAdam writes "I guess all that waiting and hoping was in vain. HP just sent out an email officially claiming to be out of TouchPads. 'Dear Valued Customer: Making sure customers have a positive experience when they purchase our products is a priority for us. In some cases, limited inventory makes it challenging to fulfill all customer orders. As you signed up for updates on the HP TouchPad, we wanted you to know that we are officially out of stock. Some retailers will have some stock available, but our online inventory is depleted.'"

First time accepted submitter yourlord writes "Hewlett-Packard Co. has decided to keep its PC division. So says its newly appointed CEO Meg Whitman. Whitman, the former eBay chieftain, categorically rejected a plan offered up by her predecessor, former CEO Leo Apotheker, to either sell or spin-off this division. HP announced the decision after the close of financial markets today."

sciencehabit writes with this selection from Science: "Presidential hopeful Ron Paul's new proposal to slash federal spending would wipe out large chunks of the government's research portfolio. The congressman from Texas and Republican candidate has unveiled a budget plan to reduce the deficit that would eliminate five federal departments: Energy, Commerce, Interior, Education, and Housing and Urban Development. In one fell swoop, such a step would erase, among other programs, the Energy Department's $5-billion Office of Science, the $4.5-billion National Oceanic and Atmospheric Administration, the $750-million National Institute of Standards and Technology, and the $1.1-billion U.S. Geological Survey."

sciencehabit writes "Here's what we know about the evolution of flight: By about 150 million years ago, the forests were filled with flying — or perhaps just gliding — dinosaurs like Archaeopteryx, possibly similar to the ancestor of modern birds. What we don't know is what primitive wings were used for before bird ancestors could fly. A new study (abstract) provides some fresh data for this debate, not from fossils but from a winged robot (video included)."

Barence writes "PC Pro has published a comprehensive guide to installing Android on a HP TouchPad using CyanogenMod's alpha Android release. The mod, which is based on Android 2.3 (Gingerbread) instead of 3.0 (Honeycomb, the source code of which is yet to be released) 'performs similarly to the Tegra 2-based tablets we've seen from the likes of Asus and Samsung,' according to PC Pro. 'The only real problem we hit was some apps refusing to install from the Android Market because they didn't recognise the hardware,' although there are ways around it."

Esther Schindler writes "'Over the past century a lot of science fiction has been published, showcasing a lot of wild ideas, and if you sit enough authors at enough typewriters or word processors, somebody is bound to get a few things right. Science fiction's greater influence, though, goes beyond whether or not the authors can make a good guess,' writes Kevin J. Anderson in Science Fiction's Take on the Future of Computers: Visionaries and Imaginaries. 'Rather than predicting the future, the SF genre is much better at inspiring the future. Visionaries read or see cool ideas in their favorite SF books or films, then decide how to make it a reality.' So Anderson assembled a set of visionaries, and asked them where they thought computing is headed: Mike Resnick, Robert J. Sawyer, Greg Bear, Michael A. Stackpole, Dr. Gregory Benford, and Christopher Paolini gaze into their crystal balls. 'Forget artificial intelligence. The future of computing is artificial consciousness, and it will be here within 20 years, and maybe much sooner than that,' says Sawyer. 'Our future wired world will have smart, wireless robots — gofers in hospitals, security guards with IR vision at night, lawn mowers, etc. We ourselves will be wired, with devices and embedded sensors taking in data and giving it out — a two way street,' contributes Benford."

yesakmac joins the teeming hordes of successful Slashdot submitters, with this excerpt from PC World that says the frenzied effort to port Android to HP's discontinued TouchPad has actually succeeded: "CyanogenMod also released a 'lower your expectations edition' release guide to let you know exactly what is working (or not) under the hood. Modders will be happy to know that basically all the TouchPad's guts are recognized. It supports dual-booting and fake SD cards in case you need to restore the TouchPad. What does not work, though, is the camera, which can only be used for video chat. Power efficiency is still an issue, too. As for the final build, CyanogenMod says they won't be giving a hard date, and that it will be ready when it is ready."

bdking writes "After signing off on former CEO Leo Apotheker's proposal to spin off or sell HP's personal computer unit, the company's braintrust is reassessing the wisdom of dumping a division that contributes nearly 30% of revenue and holds together a valuable supply chain." HP appears concerned not so much for the revenue generated by PC hardware, but instead by access to various distribution and supply channels. It seems that just announcing a spin-off has affected their access to retail distributors.

packetrat writes "Hewlett Packard may not be in danger as a company, but its future in the PC business is in doubt, thanks to former CEO Leo Apotheker's maneuvers to turn HP into IBM. This article at Ars says Meg Whitman should go ahead and sell off the PC business — mostly because HP's management is so inept, it would likely do better without them. Agilent seems to be doing okay since it was spun off in 1999, but HP may have spun off its soul in the process."

Spy Hunter writes "Memristors are the basis of a new memory technology being developed by HP and Hynix. At the International Electronics Forum, Stan Williams, senior fellow at HP Labs, said, 'We're planning to put a replacement chip on the market to go up against flash within a year and a half. We're running hundreds of wafers through the fab, and we're way ahead of where we thought we would be at this moment in time.' They're not stopping at a flash replacement either, with Williams saying, 'In 2014 possibly, or certainly by 2015, we will have a competitor for DRAM and then we'll replace SRAM.' With a non-volatile replacement for DRAM and SRAM, will we soon see the end of the reboot entirely?"

angry tapir writes "HP is investigating how several TouchPads reportedly shipped to end users running Android, instead of webOS. Shortly after HP announced it would stop selling TouchPads and began offering the remaining tablets for US$99, reports surfaced from a few users who say they received TouchPads that run Android instead of HP's webOS software. At the same time, developers have been working on porting Android to the TouchPad, since it's uncertain how much support and development HP will dedicate to webOS in the future."

wiredmikey writes "Hitachi-LG Data Storage, a joint venture between Hitachi and LG Electronics, has agreed to plead guilty and to pay a $21.1 million criminal fine for its part in a scheme to rig bids and fix prices of optical disk drives. According to the Department of Justice, the company had conspired with others to rig the bidding process on optical disk drives sold to Dell, HP, and Microsoft. Court documents show that Dell and HP hosted optical disk drive procurement events in which bidders would be awarded varying amounts of optical disk drive supply depending on where their pricing ranked."

sciencehabit writes "Among the prolific paintings and other art in the 8 kilometer-long Rouffignac cave system in southwestern France are a number of unusual markings known as finger flutings, which are made by people dragging their hands through the soft silt that lines the cave's walls. By analyzing the finger flutings of modern humans, researchers discovered that the ratio of the distance between the three middle fingers indicate that many of the cave artists were very young children, one as young as 2 or 3 years old. The researchers were also able to tell the children's genders from the shape of the fingers."

Nemilar writes with this excerpt from VentureBeat: "Who will save what's left of Palm from HP's bumbling? It could be Amazon, as the online retailing giant is in serious negotiations to snap up Palm from HP. No other company seems as fitting a home for Palm and its webOS software. It's worth noting that former Palm CEO Jon Rubinstein, who now holds a vague 'product innovation' role at HP's Personal Services Group, joined Amazon's board late last year."

Earl The Squirrel joins the army of Slashdot submitters, with a story that dampens my hopes to get one of the last (cheap) HP Touch Pads. He writes: "Today HP made available to their employees (via their EPP store) one last batch of HP Touch Pads. The response has been so overwhelming that if you go to the HP store right now, you'll get the 'Please try again later' page. HP employees have 'slashdotted' their own store."

Esther Schindler writes "In this interview with Steven Vaughan-Nichols, Linus Torvalds shares hard-won wisdom about managing software development projects, including encouraging community involvement, the importance of programming tools, and ensuring the project stays on track. For instance, regarding getting people to contribute to your project, he says, 'If you start off with some "kumba-ya feeling" where you think people from all the world are going to come together to make a better world by working together on your project, you probably won't be going very far.'"

hapworth writes "Analysis published today shows that Hewlett-Packard has shelled out over $80 million to get rid of three CEOs since 2005. The first CEO to take her expensive exit, Carly Fiorina, received over $42 million, once stocks, options, and pension are factored in. Mark Hurd, after just four years, received $12.2 million to take his exit; and now, after 11 months, Leo Apotheker will walk out with a reported $25.2 million in severance. With eBay's Meg Whitman in as the new CEO at HP, industry analyst Robert McGarvey writes today that 'the HP gig could help Whitman replenish her personal coffers, depleted by the pumping of $119 million into a futile bid to become California's governor.'"
