We've been working hard on the new dynamic Slashdot project (logged in users can enable this by enabling the beta index in their user preferences). I just wanted to quickly mention that there are keybindings on the index. The WASD and VI movement keys do stuff that we like, and the faq has the complete list. Also, if you are using Firefox or have Index2 beta enabled, you can click 'More' in the footer at the end of the page to load the next block of stories in-line without a page refresh. We're experimenting now with page sizes to balance load times against the likelihood that you'll click. More features will be coming soon, but the main thing on our agenda now is optimization. The beta index2 is sloooow and that's gotta change. We're aiming for 2 major optimizations this week (CSS Sprites, and removing an old YUI library) that I'm hoping will put the beta page render time into the "Sane" time frame (which, in case you are wondering, is several seconds faster than that "Insane" time frame we're currently seeing).

Frequent Slashdot contributor Bennett Haselton writes " Amid the latest 'sexting' controversy, here is a proposal for a scientifically objective method to determine whether a picture constitutes child pornography. This is a harder problem than it seems, but not for the reasons you'd think. And it raises questions about how the same scientific principles could be applied to other matters of law."

An anonymous reader writes "The president of the Authors Guild has launched a rant in the NY Times about how the Kindle 2 provides Text-to-Speech capabilities that, oh the horror, allow the user to have any text on the Kindle read to her. Roy Blunt, Jr. moans that this is copyright infringement of audio books, and that Kindle users should be forced to pay royalties on audio even though they've already paid for the text version of a book! Amazingly he harps on about how TTS technology has become so good that it may replace humans — and then uses this to argue that it's unfair for Kindle to provide TTS! I think the Authors Guild need a new president — someone less of a Luddite, and more familiar with copyright law." (See also the Guild's executive director's similar claims that reading aloud, royalty-free, is an illegal function of software.)

InternetVoting writes "After all the controversy surrounding Obama's Blackberry, word has come that he will get to keep it. Few details are available and neither the National Security Agency nor the White House are talking. The current rumor is that the Blackberry will be used exclusively for personal use and a Sectera Edge will be used for official communications."

snydeq writes "Programmers are finding themselves increasingly drawn to the Mac as a development platform, in large part due to Apple's decision to move to Intel chips and to embrace virtualization of other OSes, which has turned Mac OS X into a flexible tool for development, InfoWorld reports. The explosion of interest in smartphone development is helping the trend, with iPhone development lock-in to the Mac environment the chief motivating factor for Apple as a platform of choice for mobile development. Yet for many, the Mac remains sluggish and poorly tuned for development, with developers citing its virtual memory system's poor performance in paging data in and out of memory and likening use of the default-network file system, AFS, to engaging oneself with 'some kind of passive-aggressive torture.' What remains unclear is whether Apple will lend an ear to this new wave of Mac-based development or continue to develop products that lock out uses programmers expect."

phantomfive writes "Forbes is reporting that despite Radiohead giving their latest album away 'for free', more copies of the album were pirated than downloaded from their site. Commentators offered up the opinion that this was probably more out of habit than malice. People download from regular BitTorrent sources, and may not have fully understood the band's very new approach to the subject. Regardless, Readiohead's efforts are having some measurable effect, as noted by the chairman of EMI: 'The industry, rather than embracing digitalization and the opportunities it brings for promotion of product and distribution through multiple channels, has stuck its head in the sand. Radiohead's actions are a wake-up call which we should all welcome and respond to with creativity and energy.'"

An anonymous reader writes to tell us that this week at the JavaOne Conference, Sun debuted it's answer to the iPhone. While it is still months away from being a reality this phone is set to put them in direct competition with some of the top cellphone vendors. "Java Mobile FX is "a complete desktop-scale environment that puts the network in your hand," said Richard Green, executive vice president of Sun's software group, announcing the product in his keynote address. Sun ported the Savaje code to a Linux kernel and is expanding the applications programming interfaces and set of developer tools that will ship with it. It plans to make the code available on other platforms in the future. Sun has no licensees for Java Mobile FX yet. However, it is in conversations with carriers and handset makers now and hopes to see cellphones using the software ship in early 2008. "

Vicissidude writes "A team of American and British researchers has made a cloak of invisibility. In their experiment the scientists used microwaves to try and detect a copper cylinder. Like light and radar waves, microwaves bounce off objects making them visible and creating a shadow, though it has to be detected with instruments. If you can hide something from microwaves, you can hide it from radar and visible light. In effect the device, made of metamaterials — engineered mixtures of metal and circuit board materials, which could include ceramic, Teflon or fiber composite materials — channels the microwaves around the object being hidden. When water flows around a rock, co-author David R. Smith explained, the water recombines after it passes the rock and people looking at the water downstream would never know it had passed a rock. The first working cloak was in only two dimensions and did cast a small shadow, Smith acknowledged. The next step is to go for three dimensions and to eliminate any shadow."
