mikejuk writes: Google may have been wowing the web with its trippy images from neural networks but meanwhile it has just revealed that it has applied for at least six patents on fundamental neural network and AI [concepts]. This isn't good for academic research or for the development of AI by companies. The patents are on very specific things invented by Geoffrey Hinton's team like using drop out during training, or modifying data to provide additional training cases, but also include very general ideas such as classification itself. If Google was granted a patent on classification it would cover just about every method used for pattern recognition! You might make the charitable assumption that Google has just patented the ideas so that it can protect them — i.e. to stop other more evil companies from patenting them and extracting fees from open source implementations of machine learning libraries. Google has just started an AI arms race, and you can expect others to follow.

mrspoonsi sends news of an IBM study (PDF) which found that discarded laptop batteries could be used to power lights in areas where there's little or no electrical grid. Of the sample IBM tested, 70% of the used batteries were able to power an LED light for more than four hours every day throughout an entire year. The concept was trialed in the Indian city of Bangalore this year. The adapted power packs are expected to prove popular with street vendors, who are not on the electric grid, as well as poor families living in slums. The IBM team created what they called an UrJar — a device that uses lithium-ion cells from the old batteries to power low-energy DC devices, such as a light. The researchers are aiming to help the approximately 400 million people in India who are off grid.

Gary Marcus writes in the New Yorker about the state of artificial intelligence, and how we take it for granted that AI involves a very particular, very narrow definition of intelligence. A computer's ability to answer questions is still largely dependent on whether the computer has seen that question before. Quoting: "Siri and Google’s voice searches may be able to understand canned sentences like 'What movies are showing near me at seven o’clock?,' but what about questions—'Can an alligator run the hundred-metre hurdles?'—that nobody has heard before? Any ordinary adult can figure that one out. (No. Alligators can’t hurdle.) But if you type the question into Google, you get information about Florida Gators track and field. Other search engines, like Wolfram Alpha, can’t answer the question, either. Watson, the computer system that won “Jeopardy!,” likely wouldn’t do much better. In a terrific paper just presented at the premier international conference on artificial intelligence (PDF), Levesque, a University of Toronto computer scientist who studies these questions, has taken just about everyone in the field of A.I. to task. ...Levesque argues that the Turing test is almost meaningless, because it is far too easy to game. ... To try and get the field back on track, Levesque is encouraging artificial-intelligence researchers to consider a different test that is much harder to game ..."

An anonymous reader writes "A Google study of DRAM errors in their data centers found that they are hundreds to thousands of times more common than has been previously believed. Hard errors may be the most common failure type. The DIMMs themselves appear to be of good quality, and bad mobo design may be the biggest problem." Here is the study (PDF), which Google engineers published with a researcher from the University of Toronto.

dominique_cimafranca writes "The Dynamic Graphics Project of the University of Toronto has released a pretty nifty 3D curve sketching system. Apart from the large drawing area, the tablet software looks very intuitive to artists. From the site: 'The system coherently integrates existing techniques of sketch-based interaction with a number of novel and enhanced features. Novel contributions of the system include automatic view rotation to improve curve sketchability, an axis widget for sketch surface selection, and implicitly inferred changes between sketching techniques. We also improve on a number of existing ideas such as a virtual sketchbook, simplified 2D and 3D view navigation, multi-stroke NURBS curve creation, and a cohesive gesture vocabulary.'"

Daniel Wigdor asks: "I'm a PhD candidate doing an internship at a major American UI research lab. They distribute an input/output hardware device to research labs, along with a Java API for the development of 'concept pieces' (here's an example from a university). Java was chosen because it was simple, and seemed, at the time, to be the language of choice for UI researchers in both the corporate and academic worlds. There is now pressure to switch from Java to C#, since they don't have the resources to maintain an SDK for both. We're not at all concerned with system performance, since this is only for concept-development: it's really just about accessibility for newcomers to the hardware. Given that, what would the community advise by way of a choice between Java and C#?"

Eh-Wire writes "At the recent ACM Conference on Computers, Freedom and Privacy, Steve Mann - cyborg numero uno - led a troop of conference attendees on a surveillance camera hunt and digital capture. Their antics confounded rent-a-cops in a downtown Seattle shopping mall who had difficulty with the concept of having their surveillance cameras surveilled."

d4 asks: "Thad Starner has been using a wearable computer daily since 1993, and Steve Mann has had an impressive amount of press coverage over the years. But if you want wearable computing in 2005, it seems you must build your own system. Why, after all this time and attention, are wearables still not commercially available?"

museumpeace writes "Stuck for ideas about cheapest/fastest/most realistic rendering technology for that new video game you want to develop? Here is a great list of links and resources. The very latest is a tool mentioned on Technology Review which, if you feed it just a few dozen frames of a video of , for instance, Kurt Shilling pitching, can extrapolate a library of animated gestures or actions from just that sample. This new technique is already licensed to Electronic Arts. It was developed by Aaron Hertzman and Zoran Popovic and grew out of earlier work by Hertzman at NYU and a busy curriculum of computer graphics accomplishments by Popovic."

scsiiscs writes "I have just had the pleasure of reading Lysergically Yours, the first offering from author Frank Duff. As the chemically aware among you may have guessed from the title, this is a novel which deals in part with the synthesis of and culture surrounding LSD. It is much more than just a drug book though, and what's better, it has been released under a Creative Commons license. " Read on for the rest of his review. Lysergically Yours author Frank Duff pages 120 publisher Insurgent Productions/No Media Kings rating Excellent (10) reviewer Ben Konrath ISBN 097348070X summary Clandestine chemists accidentally open the doorway into new modes of human consciousness.

April 16th, 1945: Dr. Albert Hoffman's work on obstetrics pharmacology at Sandoz Laboratories is unexpectedly interrupted by a "stream of fantastic pictures and extraordinary shapes with intense, kaleidoscopic play of colors."[1]

The following weeks saw Dr. Hoffman and his colleagues perform a series of self-experimentations which led to the discovery of the psychotropic effects of D-lysergic acid diethylamide 25, the most potent hallucinogen yet discovered -- and better known as LSD. The doors were suddenly flung open for a new age of exploration into the human mind. Government sanctions however quickly put an end to this line of research. Lysergically Yours, the first novel from Toronto-based author Duff supposes that this research program is still going strong, but not in the places one may traditionally think to look for it.

The reader is first introduced to Johnny, a computer science student at the University of Toronto and one-time high school acid dealer. It is through the lens of Johnny that the reader meets the book's delightfully diverse cast of supporting characters. From Lyle the punk-rock chemist to Tinka the manic witch and surprisingly affable career criminal Ivan, Duff continuously delivers with characters that you almost expect to run into the next time you're on campus despite the fact that they are so eccentric as to verge on unbelievable. As a former University of Toronto student myself, I must admit that the setting of the book was also wonderfully realized. From Convocation Hall to Lash Miller Chemical Laboratories to the basement of Hart House, Lysergically Yours romps across the university and the city bringing to life each locale that it touches.

The story itself is somewhat hard to classify. The opening throws Johnny and the reader into a very tense scene in which Johnny is the prisoner of Korean and Vietnamese mobsters and the building in which he is being held is being assaulted from outside by unknown forces. From this action-movie introduction, the story flashes back and begins to relate a decidedly non-action-movie drug culture caper story wherein Lyle and Johnny attempt to fund illegal research and a hedonistic lifestyle through the synthesis and sale of LSD. By the end however, as Johnny and Lyle find themselves deeper and deeper in trouble, the plot of Lysergically Yours verges strongly on the science fictional, yet Duff manages to wrap it all up into a bundle which leaves the reader feeling both entertained and satisfied.

At times the discussion of the technical details of drug synthesis and of various less than legal money-making schemes seem unnecessarily verbose, but perhaps they will be appreciated by those who are more familiar with the fields or even looking for a few pointers. In general however, Duff's prose is poetic in its spareness and simplicity. His dialogue also is unflowery and believable, conveying a real sense of character and situation. Even the far-sweeping conclusion of the novel, suggesting a world forever and fundamentally changed by the actions of a couple of punk rockers, is presented in a crisp and unapologetic style. As a reader, I could not help but be reminded of Neal Stephenson and, to a certain extent, Philip K. Dick.

My largest complaint with Lysergically Yours is that it is too short. Weighing in at 120 pages, the book is an easy read but leaves you feeling that it could have easily been expanded to fill twice as many. Still, in a time when most books seem to be guilty of the opposite sin, I am willing to forgive Frank Duff this indiscretion.

Another thing which makes this novel worth noticing is that it is released in affiliation with No Media Kings, an organization started by Toronto-based author Jim Munroe to promote a return to grass-roots media. In accordance with this "media of the people, by the people and for the people" ethos, Frank Duff has released the novel as a free e-text under the Creative Commons Attribution/Non-Commercial/Share-Alike license. This license not only allows the text of the novel to be freely distributed in any medium, but also explicitly allows for anyone to create derivative works from the novel for any non-commercial purpose. The use of this contract follows in the footsteps of successful science fiction author Cory Doctorow. The book is available as a physical artifact at a variety of small bookstores or directly from the author via his website where the e-book and several of his other shorter works are also available for free download.

derrickoswald writes "Today's Ottawa Citizen is running a report in the TechWeekly section on the recent open source conference in Toronto organized by U of T's interdisciplinary Knowledge Media Design Institute and last month's Real World Linux trade show. It highlights the extremely poor Extremadura region of Spain's success story using open source to bootstrap themselves technologically. Quotes from FOSS luminaries include: 'Who controls the software, controls life. Well, it had better us. That's the real political meaning of the free software movement,' said Eben Moglen. Open source 'was the default way you built Internet Infrastructure. You wrote code and released it without trying to commercialize and monetize it,' said Brian Behldendorf." Newsforge (also part of OSDN) has a series of reports on the conference: Day 1, Day 2, Day 3.

aphyscher writes "About a year ago, there was an announcement that M.J. Dunwoody had proved the (in)famous Poincare conjecture. His paper turned out to have a slight problem, and so it remained unsolved... until perhaps now! Sergey Nikitin has posted a preprint of what may perhaps be an actual proof."

jafuser writes: "Prof. Steve Mann (of cyborg fame) has a detailed technical description on his site that demonstrates a method of transforming video into a high resolution composite image. Pictures are seamlessly mosaiced together to form one larger picture of the scene. Portions of the video that were "zoomed in" will result in a much clearer region in the final picture. I wonder if this could be used in a linear sequence to 'restore' old video to higher resolutions? It's on sourceforge; download and play!" Mann has been experimenting with such composites using personal video cameras for years.

_J_ writes: "The Toronto Star has This Article on their Web site about method to "trap light." Since they call it a break-through to making an optical system it implies that light can be stored in a type of memory. I hope that this implies light-using logical gates." While this sounds like one more Holy Grail Found! announcement, the work that professors Ozin and John (mentioned in article) have done makes it sound like they're no slouches in the photonics or nanotech departments.

Chris Siebenmann is curious about the following: "As part of thinking about disaster recovery for our Linux machines, I'm looking at ways to back up and restore the partition tables of our disks, because it's about the only piece of data about the system that isn't backed up. We've got printouts of the partitioning details (via 'fdisk -l' and 'cfdisk -P') but I'd rather not go through the error-prone bit of typing them in again to partition new disks. Is there any program that saves and restores partition tables? Better yet, is there one that saves partition tables in some reasonably abstract levels, describing the size of the partitions and how they're structured in an editable form, with a restoration program that can cope with a not-completely-identical disk to restore them onto? (Such a program would be a useful part of an automated Linux setup and install system, too.)"
