whoever57 writes "According to Prof Kubiatowicz from Berkeley, each time an additional book is downloaded to an e-reader, the mass of the e-reader increases. The effect doesn't really make the devices more difficult to carry: the professor calculates that 4GB of books would increase its weight by a billionth of a billionth of a gram— about the mass of a single virus or DNA molecule."

Michael J. Ross writes "If you need a theme for a web site based on Drupal 7, then you have a few options for obtaining one. You could go with an existing theme, but the current crop of prebuilt themes is even more limited for Drupal 7 than its predecessor. You could hire a dedicated Drupal themer to create one for you. Or, to avoid the expense, you could try to build your own. In that case, you will need to get up to speed on the changes in the Drupal presentation layer. Unfortunately, most of the Drupal 7 books devote only one or two chapters to the topic. Several Drupal training firms offer video instruction, but the bulk of their material is still geared to version 6, or even 5. The online documentation is of little help. Yet there is a book that is wholly dedicated to the topic: Drupal 7 Themes, authored by Ric Shreves." Read on for the rest of Michael's review.

theodp writes "On Tuesday, Amazon received a patent on 'Customizing Gift Instrument Experiences for Recipients', which allows a gift card giver to not only recommend items via the gift card but also to restrict the types of things the card can be used to buy — and to get a report back on what the recipient purchases. From the patent: 'The rules could also specify that the available media be constrained by a rating, such as a parental rating (e.g. G, PG, PG-13, R, etc.) or media that excludes explicit lyrics or language. In other examples, the gift instrument purchaser directs that the gift instrument can only be redeemed for books (e.g., not video games), books of a selected genre (e.g., romance, action, historical, etc.), books having a selected author, etc.'"

hype7 writes "With yesterday's release of the Steve Jobs biography, a raft of interesting information has come to light — including Jobs' favorite books. There's one book there listed as 'profoundly moving' to Jobs — The Innovator's Dilemma by innovation professor Clayton Christensen. The book explains how in the pursuit of profit, good managers leave their companies open to disruption. There's an interesting article over at the Harvard Business Review that explains how disruption works, and how Jobs managed to solve the dilemma by focusing Apple on products rather than profit."

First time accepted submitter Alt-kun writes "Like Amazon last month, Kobo is now making the jump to an Android-based tablet e-reader. Priced at $200 and available on October 28th, the Kobo Vox is set to complete with the Kindle Fire rather than the iPad. While Kobo can't match up with Amazon's sheer mass of available content, it is partnered with various major book sellers and has a good-sized base of existing customers. Also, previous Kobo products have made a point of supporting open standards for media, and that will presumably continue with the Vox. For those who aren't familiar with Kobo: they have little presence in the US, but their e-readers are fairly popular in Canada, Australia, and a number of other countries."

Nate the greatest writes "It looks like Amazon won't be adopting Epub after all. [Thursday] Amazon released some technical details on the new Kindle ebook format, which they are calling Kindle 8. There are a lot of interesting changes to the file, including new formatting and SVG images. The new tags are going to open up a whole lot of new possibilities for making Kindle ebooks."

Hugh Pickens writes "George Anders writes that companies like Facebook are finding that old-fashioned hiring channels aren't paying off fast enough and are publishing gnarly programming challenges and inviting engineers anywhere to solve them. 'We developed this theory that occasionally there were these brilliant people out there who hadn't found their way to Silicon Valley,' says Facebook engineer Yishan Wong who volunteered to draft puzzles so hard that he couldn't solve them. The problems aren't the superficial brainteasers that some companies use, like estimating the number of basketballs sold every year or why are manhole covers round, but developing sophisticated algorithms — like ways of automatically seating a clique of people in a movie theater, given that best friends want to be side by side and rivals need to be far apart. David Eisenstat has compiled an unofficial guide to the Facebook Engineering Puzzles. Our favorite: 'Liar, Lair,' seems particularly applicable to slashdot: 'As a newbie on a particular internet discussion board, you notice a distinct trend among its veteran members; everyone seems to be either unfailingly honest or compulsively deceptive,' says the description of the problem. 'You must write a program to determine, given all the information you've collected from the discussion board members, which members have the same attitude toward telling the truth.'"

destinyland writes "A California librarian is urging librarians to complain to Amazon over issues with privacy and advertising in Amazon's new Kindle ebook lending program for libraries. 'In our greedy attempt to get content into our users' hands, we have failed to uphold the highest principle of our profession, which is intellectual freedom,' she argues in a 10-minute video. (Read the transcript here). Amazon keeps your history of reading library ebooks on their corporate servers, 'so it's an instant violation of all of our privacy policies. And we haven't told people that, and we need to tell people that.' And while many libraries have strict policies against endorsing a particular product, the check-out process concludes on Amazon.com with a pitch urging library patrons to purchase more Amazon books — and there's even book-buying plugs in their 'due date' reminders."

Hugh Pickens writes writes "T. N. Tobias writes that over the summer, over 60,000 people voted at NPR to select the top 100 science fiction and fantasy books of all time. The result? A list of 100 books with a wide range of styles, little context, and absolutely no pithy commentary to help readers actually choose something to read from it. Now SF Signal has come to the rescue with a 3800 x 2300 flowchart with over 325 decision points to help you find the perfect SF or Fantasy book to meet your tastes. Don't like to scroll? There's an interactive version that let's you answer a series of questions to find the perfect SF book."

eldavojohn writes "The Information: A History, a Theory, a Flood by James Gleick has a rather nebulous title and the subtitle doesn't really help one understand what this book hopes to be about. The extensive citations are welcomed as the author barely scratches the surface of any theory of information. It also cherry picks odd and interesting facets of the history of information but presents them in a chronologically challenged order. This book is, however, a flood and as a result it could best be described as a rambling, romantic love note to Information — eloquently written and at times wondrously inspiring but at the same time imparting very little actual knowledge or tools to the reader. If I were half my age, this book would be the perfect fit for me (just like Chaos was) but knowing all the punchlines and how the story ends ahead of time rather ruined it for me. While wandering through interesting anecdotes, Gleick masks the reader from most of the gory details." Read on for the rest of eldavojohn's review.

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."

Hugh Pickens writes "David Streitfeld reports that Amazon is aggressively wooing top authors, gnawing away at the services publishers, critics and agents used to provide. 'Everyone's afraid of Amazon,' says Richard Curtis, a longtime agent who is also an e-book publisher. 'The only really necessary people in the publishing process now are the writer and reader,' adds Russell Grandinetti, one of Amazon's top executives. 'Everyone who stands between those two has both risk and opportunity.' But publishers are fighting back at writers who publish with Amazon. In 2010 Kiana Davenport signed with a division of Penguin for The Chinese Soldier's Daughter, a Civil War love story, and received a $20,000 advance. In the meantime Davenport packaged several award-winning short stories she had written 20 years ago and packaged them in an e-book, Cannibal Nights, available on Amazon. When Penguin found out, it went 'ballistic,' accusing her of breaking her contractual promise to avoid competition, canceling her novel, and suing Davenport to recover her advance. Davenport knows her crime: 'Sleeping with the enemy? Perhaps. But now I know who the enemy is.'"

You asked William Shatner questions, and Shatner replied. It's not the first time he's answered questions for Slashdot (that was in 2002), but Shatner's given a bit more insight this time into what makes an 80-year-old actor-author-sportsman-father-filmmaker tick as fast as ever. Did he mention that he's got a one-man show about to open? And a new album? Note: Typically Shatner, he's also chosen to ignore (or transcend) the usual Slashdot interview structure, and written his answers in his own style, which is why the format looks a little different from most of our interviews. Thanks, Bill. (Read on for his answers.)

Hugh Pickens writes "After a 45-year production run, Mazda Motor Corp announced that the latest edition of the Mazda RX-8 will end production in June 2012. The Japanese automaker ... introduced its first rotary engine car in 1967 and is the only automaker in the world that makes rotary engine vehicles, once the darling of the automotive industry. Such engines have fewer moving parts and are quieter than comparable piston engines but are more expensive to manufacture and consume more fuel. Cumulative sales of Mazda vehicles with rotary engines total about 1.995 million but Mazda sold only 2,896 RX-8 cars last year, with 1,245 of them in North America and 963 in Japan. 'Although R-X production is ending, the rotary engine will always represent the spirits of Mazda, and Mazda remains committed to its ongoing development,' says Mazda Chief Executive and President Takashi Yamanouchi recalling the victory of Mazda's rotary engine at Le Mans 20 years ago... Mazda does not have flashy green technologies in its lineup that its bigger Japanese rivals do — such as the hybrids at Toyota Motor Corp. or electric vehicles at Nissan Motor Co. The fading away of its prized rotary engine — although largely symbolic — is yet another blow."

theodp writes "In response to DC Entertainment's agreement to exclusively offer digital versions of certain titles in Amazon Kindle format, Nook maker Barnes & Noble has begun pulling DC Entertainment's graphic novels off its shelves. Confirming the decision, B&N said in a statement, 'To sell and promote the physical book in our store showrooms, and not have the eBook available for sale would undermine our promise to Barnes & Noble customers to make available any book, anywhere, anytime.' Nice to see the pair is still able to keep their feud fresh on the 11th anniversary of the 1-Click patent infringement lawsuit."

blarkon writes "With ebook prices falling and some readers even unwilling to pay more than 99 cents for an ebook, some authors are starting to consider a move back to the patronage model that was successful in providing them with a living before the widespread use of copyright. Might such a model work or are the days where a midlist author can make a living off their work a relic of the 20th century?"

First time accepted submitter osman84 writes "I've been developing web/mobile apps for some time, and have managed to build up some decent experience about usability. However, as I'm growing a team of developers now, I've noticed that most of the young ones have a very poor sense of usability. Unfortunately, since I was never really taught usability as science, I'm having trouble teaching them to develop usable apps. Are there any good books that make a good read for general usability guidelines for web/mobile apps? I have a couple from my college days, but I'd like something more recent, written in the era of mobile apps, etc."
