theodp writes "Over at Salon, Annie Keeghan does an Upton Sinclair number on the math textbook industry. In recent years, Keeghan explains, math has become the subject du jour due to government initiatives and efforts to raise the rankings of lagging U.S. students. But with state and local budgets constrained, math textbook publishers competing for fewer available dollars are rushing their products to market before their competitors, resulting in product that in many instances is inherently, tragically flawed. Keeghan writes: 'There may be a reason you can't figure out some of those math problems in your son or daughter's math text and it might have nothing at all to do with you. That math homework you're trying to help your child muddle through might include problems with no possible solution. It could be that key information or steps are missing, that the problem involves a concept your child hasn't yet been introduced to, or that the math problem is structurally unsound for a host of other reasons.' The comments on Keeghan's article are also an eye-opener — here's a sample: 'Sales and marketing budgets are astronomical because the expenses pay off more than investments in product. Sadly, most teachers are not curriculum experts and are swayed by the surface pitches. Teachers make the decisions, but are not the users (students) nor are they spending their own money. As a result, products that make their lives easier and that come with free meals and gifts are the most successful.' So, can open source or competitions build better math textbooks?"
hey! writes "On February 18 of this year, global giant payment processor PayPal sent eBook publisher Smashwords an ultimatum: if Smashwords didn't remove all eBooks with certain erotic content from its catalog in the next several days, PayPal would immediately stop handling payments. Smashword's TOS already precluded child pornography, but now PayPal wants them to also censor depictions of consenting, non-related adults acting out incest fantasies. Likewise, fantasy novels in which human characters transform into non-humans are affected if those characters have sex. ZDNet has a summary of the impact of these changes, which would among other things ban Vladmir Nabokov's Lolita. As outrage mounts, finger pointing is in full swing. Smashwords blames PayPal, and PayPal blames the banks it deals with. The crux seems to be that erotica buyers have a higher rate of 'chargebacks' — customers who buy stuff then demand their money back. Fair enough, but is a customer really more likely to return a book because it depicts one kind of fantasy between consenting adults vs. another? Perhaps the problem is just the quality of writing." Note: as you can probably tell from the summary, the linked articles (while factual in nature) discuss subjects that may not be suitable for workplace reading.
An anonymous reader writes "PC Magazine reports that even while Amazon was building their Kindle Fire tablet, it was already planning on a much larger model that 'will be its marquee product and the hopeful cornerstone of its tablet strategy.' Amazon's already begun offering $30 discounts on refurbished 7-inch Kindle Fire tablets, matching last week's new aggressive pricing from Barnes and Noble on their color touchscreen Nook. But PCMag argues that the 7-inch color Kindle was simply a 'beta' release of the larger device to come. 'In no way was Amazon being dishonest with its customers... To be truly fair, many people may never want a screen larger than seven inches because of the associated weight and bulk.' But the author argues that its real purpose may have been as a test run to gather important real-world data for their ultimate war with the iPad. 'After all, as industry insiders joke, all first-generation products, whether hardware or software, are really "beta" programs disguised as initial launches.'"
braindrainbahrain writes "Coincidence or conspiracy? Two new science fiction magazines have just been announced and they are both being published by more serious science publications. New Scientist magazine has announced the publication of Arc, 'A new digital magazine about the future.' Arc features such articles as 'The best time travel movie ever made' and 'The future of science fiction, games, galleries — and futurism.' They are advertising new fact and fiction from the likes of Maragret Atwood and Alastair Reynold. The MIT Technology Review has announced the TRSF, dubbed 'the first installment of a to-be-annual "hard" SF collection.' Some authors: Joe Haldeman and Cory Doctorow. As an interesting note, both publications will be printed on paper for the first ('collectable') issue only; all forthcoming ones will be e-books."
First time accepted submitter dylan_k writes "In the 1990s and early 2000s, there was a lot of buzz about ideas like 'hypertext literature' and 'electronic literature.' Nowadays, it's easier to create those things than ever before, and there are plenty of digital texts but it just doesn't seem like authors are writing any new 'hypertext' literature these days. Why?"
ananyo writes "Cultural Observatory at Harvard University in Cambridge, Massachusetts is to index the whole of the ArXiv pre-print database of papers from the physical sciences, breaking down the full text of the articles into component phrases to see how often a particular word or phrase appears relative to others — a measure of how 'meme-like' a term is. The team has already applied a similar approach to 5 million books in the Google Books database to produce their n-gram viewer. But the Google Books database carries with it a major limitation: because many of the works are under copyright, users cannot be pointed to the actual source material. Applying the tool to ArXiv means it could be used to chart trends in high-energy physics, for example: a quickening pulse of papers citing the Higgs boson, for example, or a peak in papers about supersymmetry, a theory which may soon be waning."
Hugh Pickens writes "BBC reports that a growing body of evidence from both science and history suggests that eight-hours of uninterrupted sleep may be unnatural as a wealth of historical evidence reveals that humans used to sleep in two distinct chunks called first and second sleep. A book by historian Roger Ekirch, At Day's Close: Night in Times Past, unearths more than 500 references to a segmented sleeping pattern — in diaries, court records, medical books and literature, from Homer's Odyssey to an anthropological account of modern tribes in Nigeria. 'It's not just the number of references — it is the way they refer to it, as if it was common knowledge,' says Ekirch. References to the first and second sleep started to disappear during the late 17th Century with improvements in street lighting, domestic lighting and a surge in coffee houses — which were sometimes open all night. Today most people seem to have adapted quite well to the eight-hour sleep, but Ekirch believes many sleeping problems may have roots in the human body's natural preference for segmented sleep which could be the root of a condition called sleep maintenance insomnia, where people wake during the night and have trouble getting back to sleep. 'Our pattern of consolidated sleep has been a relatively recent development, another product of the industrial age, while segmented sleep was long the natural form of our slumber, having a provenance as old as humankind,' says Ekrich, adding that we may 'choose to emulate our ancestors, for whom the dead of night, rather than being a source of dread, often afforded a welcome refuge from the regimen of daily life.'"
First time accepted submitter benrothke writes "It is said that the song Wipe Out launched a generation of drummers. In the world of information security, the classic Applied Cryptography: Protocols, Algorithms, and Source Code in C by Bruce Schneier may have been the book that launched a generation of new cryptographers. Schneier's latest work of art is Liars and Outliers: Enabling the Trust that Society Needs to Thrive. For those that are looking for a follow-up to Applied Cryptography, this it is not. In fact, it is hard to classify this as an information security title and in fact the book is marked for the current affairs/sociology section. Whatever section this book ultimately falls in, the reader will find that Schneier is one of the most original thinkers around." Keep reading for the rest of Ben's review.
New submitter SpockLogic writes "The Telegraphs has a tongue in cheek essay in praise of eternal copyright by the founder of an online games company. Quoting: 'Imagine you're a new parent at 30 years old and you've just published a bestselling new novel. Under the current system, if you lived to 70 years old and your descendants all had children at the age of 30, the copyright in your book – and thus the proceeds – would provide for your children, grandchildren, great-grandchildren, and great-great-grandchildren. But what, I ask, about your great-great-great-grandchildren? What do they get? How can our laws be so heartless as to deny them the benefit of your hard work in the name of some do-gooding concept as the "public good," simply because they were born a mere century and a half after the book was written? After all, when you wrote your book, it sprung from your mind fully-formed, without requiring any inspiration from other creative works – you owe nothing at all to the public. And what would the public do with your book, even if they had it? Most likely, they'd just make it worse.'"
jkauzlar writes "The standard Oracle JVM has about sixty 'developer' (-XX) options which are directly related to performance monitoring or tuning. With names such as 'UseMPSS' or 'AllocatePrefetchStyle', it's clear that Joe Schmo Code Monkey was not meant to be touching them, at least until he/she learned how the forbidding inner recesses of the JVM work, particularly the garbage collectors and 'just-in-time' compiler. This dense, 600-page book will not only explain these developer options and the underlying JVM technology, but discusses performance, profiling, benchmarking and related tools in surprising breadth and detail. Not all developers will gain from this knowledge and a few will surrender to the book's side-effect of being an insomnia treatment, but for those responsible for maintaining production software, this will be essential reading and a useful long-term reference."

Zothecula writes "Inspired by origami and children's pop-up books, Harvard engineers have pioneered a means of mass-producing bee-sized flying microrobots. The breakthrough mechanizes the already state-of-the art process of making Harvard's Mobee robots by hand, by mass producing flat assemblies by the sheet which can be folded and assembled in a single movement. The technique, which cunningly exploits existing machinery for making printed circuit boards, can theoretically be applied to a multitude of electromechanical machines."
First time accepted submitter Hotawa Hawk-eye writes "Tor Books has announced that the release date for the final volume in the Wheel of Time series of books, A Memory Of Light, will be January 8, 2013.

Despite Apple's protestation that the iBooks Author EULA was misinterpreted, the idea of a book publishing system that could be used to grab copyright of the prepared text is annoying — like the sort of EULAs that seem to give photo-sharing sites unlimited re-use rights of hosted personal photos. New submitter rohangarg points out a publishing system which shouldn't have such problems, and is nicely cross-platform besides: "A new open-source digital writing and publishing platform has been launched by non-profit group Sourcefabric. Booktype allows for collaborative editing and writing of books that can be easily outputted to on-demand print services and eReaders such as the Amazon Kindle, Nook, iPad, and more with a few simple clicks. Booktype source can be found here." The online demo also leads to some downloadable examples (as PDFs).
Ralph Spoilsport writes "A coalition of 17 publishing companies has shut down library.nu and ifile.it, charging them with pirating ebooks. This comes less than a month after megaupload was shut down, and SOPA was stopped. If the busting of cyberlockers continues at this pace and online library sharing dismantled, this under-reported story may well be the tip of a very big iceberg — one quite beyond the P&L sheets of publishers and striking at basic human rights as outlined in the contradictions of the UN Charter. Is this a big deal — a grim coalition of corporate power? Or just mopping up some scurvy old pirates? Or somewhere in between?" Adds new submitter roaryk, "According to the complaint, the sites offered users access to 400,000 e-books and made more than $11 million in revenue in the process. The admins, Fidel Nunez and Irina Ivanova, have been tracked down using their PayPal donation account, which was not anonymous. Despite the claims of the industry the site admins say they were barely able to cover the server costs with the revenue."
Hugh Pickens writes "Alan Jacobs writes in the Atlantic about Every Tribe Every Nation, an organization whose mission is to produce and disseminate Bibles in readable mobile-ready texts for hundreds of languages including Norsk, Potawatomie, Bahasa Indonesia, and Hawai'i Pidgin as the old missionary impulse is being turned towards some extremely difficult technical challenges. The Bible is a large, complicated text containing three quarters of a million words and the typesetting is quite complex because of the wide range of literature types found in scripture and the need for several types of note. 'For all the issues that are still to be solved, ETEN is trying to do things that the world's biggest tech companies haven't cracked yet, such as rendering minority languages correctly on mobile devices,' says Mark Howe. 'There's a unity among Bible translators and publishers that stands in stark contrast to the fractured, fratricidal smartphone industry.' But once these technical challenges are met, it won't be only Bibles only that people can get on their mobile devices, but whole new textual worlds."
