The interview and article detail where NASA and the JPL are in using solar sails for applications and research.You can read the article or skip ahead to the cool pictures of prototype and proposed solar sails. The article addresses NASA's JPL solar sail missions, but not other commercial or private projects like Cosmos 1."

Roger Whittaker writes to tell us Engadget reports that Mobileglu is offering an interesting new service that gives users the ability to read RSS feeds, flickr, del.icio.us, and other sources of content in a mobile friendly format. Think this will lead to smarter content developers making their own sites more mobile friendly, or just a few lawsuits?

Simon P. Chappell writes "This is an unusual book in a good way. It covers a subject normally the preserve of geeks while being targeted at designers. Not a common approach, but one that Jeremy Keith pulls off rather handily. Mr. Keith is an active member of the Web Standards Project's Scripting Task Force; he not only knows how to script web pages, but he knows how to use that scripting to enhance the page's conformance to standards and even increase a site's accessibility. If you are like me, and have put off working with JavaScript because of the standards issues, then this book is our notification that those days are behind us. If you are a web designer who is interested in using dynamic techniques to enhance your site, but had feared the wrath of the standards police, this book is for you." Read the rest of Simon's review.

dsandler writes "Researchers at Rice University have just released version 0.7 of FeedTree, a peer-to-peer system for distributing Web feeds faster. Instead of polling feeds independently, FeedTree users cooperate to share news updates using multicast in Pastry, a scalable p2p overlay network. FeedTree reduces the update delay for existing RSS and Atom feeds to a few minutes without putting extra stress on the webserver (anyone who's ever been temporarily banned by Slashdot's RSS feed knows this is a real concern). Feed publishers can also choose to push digitally signed updates for immediate, tamper-proof delivery to subscribers. The client software (download) runs on Linux, OS X, and Windows, and works with any desktop feed reader."

Five-Oh writes to tell us that IBM DeveloperWorks has an interesting article about the OO advantages of PHP V's new features. From the article: "PHP V5's new object-oriented programming features have raised the level of functionality in this popular language significantly. Learn how to use the dynamic features of PHP V5 to create objects that bend to fit your needs."

Eurogamer reports that Sony is flatly denying the delay of the PlayStation 3. From the article: "Sakaguchi was responding to allegations made by Merrill Lynch analyst Joe Osha in a report published late last week, in which Osha claimed that the PS3 could launch in autumn in Japan, with a US launch possibly being delayed to early 2007. 'There is no change in our original plan to release the console in spring 2006," Sakaguchi told the press in Tokyo, referring to the company's only stated goal for the launch so far - namely that the console will appear in at least one territory, most likely Japan, this spring.' They have lots of opportunities at GDC and E3 to change the public perception that their next console is still very much a work in progress.

Rob writes to tell us that at the recent Open Source Business Conference in San Francisco Microsoft's director of platform technology strategy, Bill Hilf, outlined why Microsoft is staying involved with open source. From the article: "Challenges of working [coopetively] in the open-source space include the balance between competing and cooperating with a rival, he said. Perception also is a 'big' challenge for the software giant. 'In many regards, the Microsoft open-source story lends itself to a great metaphor of David and Goliath,' he said. 'That is a challenge over perception.'"

A reader writes: "Unipage recently released a beta version of its Unipage Unifier. The Unipage encoding is a way to encode a full page with its images, CSS, Javascript, Flash, and whatnot, into just one HTML file. The 'Unipage Unifier' program instantly turns any online or local page into a 'Unipage' that can be viewed directly in a browser. It saves the mess of files when you normally save a complete web page, but maybe the bigger scoop is that now people can use 'Unipages' to send content rich documents instead of PDF. But Unipages are superior to PDF in their ability to hold functionality (Javascript), Flash animations and practically anything normally possible in a web page. Together with any program that can export into HTML you can get fully styled, dynamic, portable documents instantly. And it's free." Good luck taking down the installed base of PDF.

John Callaham writes "Nintendo's Reggie Fils-Aime has officially confirmed that the long awaited Gamecube title Zelda: Twilight Princess will be released this fall." From the article: "File-Amie also said that the game would be a Gamecube title and that there were still no plans to turn it into a game for Nintendo's next-gen Revolution console." He also took the opportunity to mention that the original DS will be phased out in late autumn, in favour of the DS Lite.

user24 writes "Several sources are reporting that China has approved a facial recognition system to be used for ID purposes in surveillance and security. From the article: 'The system, approved by the Ministry of Public Security, is expected to be used at airports, customs entrances, banks, post offices, residential areas and other public places in the near future [...] 'It has a superior advantage compared with fingerprint identification because the country doesn't have a fingerprint database for the general public,' [...] However, the country's ID cards do feature the person's photograph, which could facilitate the creation of a facial database, said Su Guangda.'"

mAriuZ writes "I've recently written two articles on this topic for Database Journal, the earlier, written after the InnoDB purchase, entitled Oracle's purchase of InnoDB, their release of Oracle Express, and the effect on MySQL, and the most recent, just after the Sleepycat purchase, entitled Pressure on MySQL increases as Oracle purchases Sleepycat, with more to come. Since I only do a monthly column for Database Journal, and things change quite quickly, I thought I'd post a few more thoughts on the topic."

SirBruce writes "As reported by Space.com, Spaceflight Now, and elsewhere, NASA is now planning to retire the Space Shuttle Atlantis by 2008, after just 5 more flghts. By doing so, they would avoid a costly and time consuming scheduled overhaul, and could still fly the remaining 12 missions (17 total) with Discovery and Endeavour, which are just now completing their ODMPs (orbiter maintenance down period). Atlantis would be kept for spare parts to keep Discovery and Endeavour flying until the shuttle program is shut down in 2010."

jeffsenter writes "The NYTimes has the story on IBM with JSR Micro advancing photolithograhy research to allow 30nm chips. Good news for Intel, AMD, Moore's Law and overclockers. The IBM researchers' technology advance allows for the same deep ultraviolet rays used to make chips today to be used at 30nm. Intel's newest CPUs are manufactured at 65nm and present technology tapped out soon after that. This buys Moore's Law a few more years."

Toasty16 writes "SPCR has an overview of using an AMD Turion 64 mobile processor in a desktop system. There's a good bit of info about motherboard compatibility and power consumption as compared to a Pentium M processor. There's also links to articles from the Techreport and LaptopLogic on the same topic. If you've been thinking about building a low power HTPC or file server, mobile processor on desktop is an interesting option."
