Reading E-Books Takes Longer Than Reading Paper Books

Tue, 07/06/2010 - 00:06
Hugh Pickens writes "PC World reports on a study showing that reading from a printed book — versus an e-book on any of the three tested devices, an iPad, Kindle 2, and PC — was a faster experience to a significant degree. Readers measured on the iPad reported reading speeds, on average, of 6.2 percent slower than their print-reading counterparts, while readers on the Kindle 2 clocked in at 10.7 percent slower. Jacob Nielsen had each participant read a short story by Ernest Hemingway. Each participant was timed, then quizzed to determine their comprehension and understanding of what they just read. Nielsen also surveyed users' satisfaction levels after operating each device (or page). For user satisfaction, the iPad, Kindle, and book all scored relatively equally at 5.8, 5.7, and 5.6 on a one-to-seven ranking scale (seven representing the best experience). The PC, however, did not fare so well, getting a usability score of 3.6."

Is PC Gaming Set For a Comeback?

Mon, 07/05/2010 - 23:17
An anonymous reader writes "A combination of factors like console penetration, piracy, and the huge inherent variability in PC hardware setups have made the PC a third-class citizen for many gaming genres, especially the kind of high-adrenaline action games that were once the PC's bread and butter. Epic is a company that has been vocal in its shift toward consoles, with many controversial statements dropped over the years in reference to piracy being the reason. So it was with some surprise that we noted Epic's VP, Mark Rein, pointing out recently that the PC is as important as ever. Why the turnaround? This article suggests that the extended length of the current console generation will drive some developers back to the PC as new games push up against hardware limits."

A Look Back At Bombing the Van Allen Belts

Mon, 07/05/2010 - 22:30
An anonymous reader points out a recent story at NPR describing one of the greatest lightshows in history — a US hydrogen bomb test 250 miles above the Pacific Ocean in 1962. The mission came about after James Van Allen confirmed the existence of radiation belts around the earth that now bear his name. As it turns out, the same day Van Allen announced his findings at a press conference, he "agreed with the military to get involved with a project to set off atomic bombs in the magnetosphere to see if they could disrupt it." According to NPR, "The plan was to send rockets hundreds of miles up, higher than the Earth's atmosphere, and then detonate nuclear weapons to see: a) If a bomb's radiation would make it harder to see what was up there (like incoming Russian missiles!); b) If an explosion would do any damage to objects nearby; c) If the Van Allen belts would move a blast down the bands to an earthly target (Moscow! for example); and — most peculiar — d) if a man-made explosion might 'alter' the natural shape of the belts." The article is accompanied by a podcast and a video with recently declassified views of the test. They also explain how the different colors of light in the sky were produced.

First Full-Sky Image From Planck Mission

Mon, 07/05/2010 - 21:44
krou writes "Six months of work has produced a remarkable full-sky map from Planck. 'It shows what is visible beyond the Earth to instruments that are sensitive to light at very long wavelengths — much longer than what we can sense with our eyes. Researchers say it is a remarkable dataset that will help them understand better how the Universe came to look the way it does now. ... Of particular note are the huge streamers of cold dust that reach thousands of light-years above and below the galactic plane. "What you see is the structure of our galaxy in gas and dust, which tells us an awful lot about what is going on in the neighborhood of the Sun; and it tells us a lot about the way galaxies form when we compare this to other galaxies," observed Professor Andrew Jaffe, a Planck team member from Imperial College London, UK.' The ESA has more details on their website, with a higher-res JPG available."

Police Stop Journalists From Photographing Metrorail System

Mon, 07/05/2010 - 20:57
schwit1 writes with this excerpt from Reason.com: "Carlos Miller, who runs the Photography Is Not a Crime blog, and veteran photojournalist Stretch Leford decided to test the photography rules in Miami-Dade's metrorail system. Before embarking on their test, they obtained written assurance from Metro Safety and Security Chief Eric Muntan that there's no law against non-commercial photography on the system. The two didn't make it past the first station before they were stopped. Employees of 50 State Security, the private firm contracted to provide the metro's security, stopped the pair first. They then called in local police. The private firm and the police then threatened the two with arrest, demanded their identification (to check them against a terrorist watch list), demanded multiple times that they stop filming, and eventually 'banned' Miller and Ledford from the metro system 'for life' (though it's doubtful they had the authority to do so)."

Compiz Project Releases C++ Based v0.9.0

Mon, 07/05/2010 - 20:08
werfu writes "Compiz 0.9.0, the first release of Compiz rewritten in C++, has been announced on the Compiz mailing list. See the announcement for more info." Compiz has for years been one of my favorite ways to make Windows users envious, despite my (Linux) systems' otherwise low-end graphics capabilities. Besides the switch to C++ from C, this release "brings a whole new developer API, splits rendering into plugins, switches the buildsystem from automake to cmake and brings minor functionality improvements."

New Material Can Store Vast Amounts of Energy

Mon, 07/05/2010 - 17:10
ElectricSteve writes "Using super-high pressures similar to those found deep in the Earth or on a giant planet, researchers from Washington State University (WSU) have created a compact, never-before-seen material capable of storing vast amounts of energy. Described by one of the researchers as 'the most condensed form of energy storage outside of nuclear energy,' the material holds potential for creating a new class of energetic materials or fuels, an energy storage device, super-oxidizing materials for destroying chemical and biological agents, and high temperature superconductors."

BBC Web Slip-Up Insults Facebook Fans

Mon, 07/05/2010 - 13:50
An anonymous reader writes "The BBC has accidentally insulted its Facebook followers by revealing a version of a new website which wasn't yet ready for public consumption and in which it referred to its social media followers as 'saddos.' The same website also features a picture of the Queen, described as the Pakistan hockey team. File this one under 'a really bad day at the office' for one web developer."

A Composer's-Eye View of the Copyright Wars

Mon, 07/05/2010 - 10:41
bonch writes "As an experiment, composer Jason Robert Brown logged onto a site illegally offering his sheet music for download and contacted hundreds of users, politely asking them to stop listing the material. Most complied, some were confused, and a few fought back. Brown chronicles a lengthy exchange he had with a teenage girl named Brenna, which provides an interesting insight into the artists' perspective of the copyright debate. He also responds to several points raised in comments to the article and says, 'I don't wish to be the enemy; I'm just a guy trying to make a living.'"

The Curious Case of SSD Performance In OS X

Mon, 07/05/2010 - 07:30
mr_sifter writes "As we've seen from previous coverage, TRIM support is vital to help SSDs maintain performance over extended periods of time — while Microsoft and the SSD manufacturers have publicized its inclusion in Windows 7, Apple has been silent on whether OS X will support it. bit-tech decided to see how SSD performance in OS X is affected by extended use — and the results, at least with the Macbook Air, are startling. The drive doesn't seem to suffer very much at all, even after huge amounts of data have been written to it."

Users Report Foul Play In App Store Rankings, Purchases

Mon, 07/05/2010 - 06:09
An anonymous reader writes "Two iPhone App developers have spotted what appears to be a hacking of the App store rankings by a rogue developer. The rankings in the books category of the US iTunes store features 40 out of 50 apps by the same app developer, Thuat Nguyen. What's more concerning is that it seems individuals' iTunes accounts have been hacked to make mass purchases of that one developer's apps." Among the comments attached to the linked story is one which suggests the security problem may lie elsewhere.

Finding Open Source Projects Looking For Help?

Mon, 07/05/2010 - 03:22
aus writes "I've been doing web development for about 10 years now. It's been very good to me, but I want to do more than write HTML, PHP, JavaScript and CSS. Since the job market isn't all that great right now in the US, it would seem that volunteering some time on an open source project would give me the satisfaction I'm looking for. The problem is finding a project that wants/needs help that I would also be interested in. I've tried browsing around on Sourceforge and Freshmeat ... is there a site somewhere that I'm not aware of that has classifieds where open source project maintainers post 'job' listings?"

Local Newspapers Use F/OSS For a Day

Mon, 07/05/2010 - 01:59
An anonymous reader writes "The Journal Register Company owns 18 small newspapers, and in honor of the July 4th holiday and Ben Franklin, the company's newsrooms produced their daily papers using only free software. The reporters were quick to note that 'the proprietary software is designed to be efficient, reliable and relatively fast for the task of producing a daily newspaper. The free substitutes, not so much.' I applaud the company for undertaking such a feat, but I hope their readership's impression of free software won't be negatively affected by the newspaper's one-day foray into F/OSS."

YouTube Hit By HTML Injection Vulnerability

Mon, 07/05/2010 - 00:35
Virak writes "Several hours ago, someone found an HTML injection vulnerability in YouTube's comment system, and since then sites such as 4chan have had a field day with popular videos. The bug is triggered by placing a <script> tag at the beginning of a post. The tag itself is escaped, but everything following it is cheerfully placed in the page as is. Blacked out pages with giant red text scrolling across them, shock site redirects, and all sorts of other fun things have been spotted. YouTube has currently blocked such comments from being posted and set the comments section to be hidden by default, and appears to be in the process of removing some of these comments, but the underlying bug does not seem to have been fixed yet."

World's Tiniest Radiometer To Power Medical Scanner

Sun, 07/04/2010 - 08:11
BuzzSkyline writes "University of Texas physicists have built the world's smallest radiometer. The minuscule radiometer is only 2 millimeters across and operates on the same principles as the common light-driven toy, which consists of spinning black and white vanes in a partially evacuated bulb. The researchers attached a mirror to their tiny radiometer and used it to rapidly scan a laser beam. Their hope is that they will be able to incorporate the radiometer into catheters to drive scanners that produce medical images of the interiors of blood vessels and organs. The devices would replace micromotors in conventional catheter-based scanners, eliminating the need to run potentially risky electrical currents into the body."

World Cup Prediction Failures

Sun, 07/04/2010 - 07:07
pdcull writes "We all read on Slashdot about the investment banks using their massive computer power and clever modeling techniques to predict the FIFA World Cup outcome. Now that Goldman Sachs's, UBS's and Danske Bank's favorite, Brazil, has been eliminated, and with JP Morgan's England long gone, the question that begs to be asked is: can we really trust these guys to predict the financial markets any better than they did World Cup?"

The Secrets of the Chaocipher Finally Revealed

Sun, 07/04/2010 - 06:01
nickpelling2 writes "In 1918, John F. Byrne invented a truly amazing cipher system, called 'The Chaocipher', that fitted inside a small cigar box, could be operated by a ten-year-old, yet produced practically unbreakable ciphertext (arguably even stronger than the Nazi Enigma machine). But now, thanks to the efforts of Chaocipher fan Moshe Rubin and the generous gift of Byrne's cryptographic effects by his daughter-in-law Pat Byrne to the National Cryptologic Museum, the secrets of the Chaocipher are finally starting to be revealed — it's a great story. To accompany Moshe Rubin's excellent textual description of the Chaocipher, I've posted a 30-second animation of the Chaocipher in action to YouTube, just in case anyone wants to see the most devious cipher of the 20th century in action (sort of)."

Spectral Imaging Reveals Jefferson Nixed 'Subjects' for 'Citizens'

Sun, 07/04/2010 - 04:59
Jamie points out this excellent piece, well timed for America's Independence Day, that says spectrographic evidence has established that the one word Thomas Jefferson fully blotted out from an early draft of the Declaration of Independence was not "resident," or "patriot," but rather "subject." This, he replaced with "citizen."
