The Science Fiction Gateway

For those of you not so deeply plugged in to the sf lit and fandom circuits of the intertubes, I’ll act as a repeater station for a signal worth passing on: venerable UK sf imprint Gollancz has announced its SFGateway project, which will integrate a growing backlist of classic sf titles in ebook formats with the also-forthcoming online Encyclopedia of Science Fiction.

Here’s the main meat from the press release, which you can read in full if you so wish:

Gollancz, the SF and Fantasy imprint of the Orion Publishing Group, announces the launch of the world’s largest digital SFF library, the SF Gateway, which will make thousands of out-of-print titles by classic genre authors available as eBooks.

Building on the remarkable success of Gollancz’s Masterworks series, the SF Gateway will launch this Autumn with more than a thousand titles by close to a hundred authors. It will build to 3,000 titles by the end of 2012, and 5,000 or more by 2014. Gollancz’s Digital Publisher Darren Nash, who joined the company in September 2010 to spearhead the project said, “The Masterworks series has been extraordinarily successful in republishing one or two key titles by a wide range of authors, but most of those authors had long careers in which they wrote dozens of novels which had fallen out of print. It seemed to us that eBooks would offer the ideal way to make them available again. This realization was the starting point for the SF Gateway.” Wherever possible, the SF Gateway will offer the complete backlist of the authors included.

The SF Gateway will be closely integrated with the recently announced new online edition of The Encyclopedia of Science Fiction, which provides an independent and definitive reference source of information on the authors and books included. Direct links between the Encyclopedia and the Gateway will provide easy access to eBook editions, for sale through all major online retailers.

The Gateway site will also act as a major community hub and social network for SF readers across the world, allowing them to interact with each other and recommend titles and authors. The site is planned to include forums, blogs, regular promotions, and is envisaged to become the natural home on the net for anyone with an interest in classic SFF.

All of a sudden, I’m genuinely interested in buying an ebook reader. (Or at least a device with ebook-reading capabilities; I suspect the standalone ebook reader will be an exemplary illustration of Chairman Bruce’s concept of “obsolete before plateau”, killed off by convergence in the tablet market, folded in as one more function for your general purpose portable computing/connectivity platform.)

I’m quite impressed at how well Gollancz have kept this on the downlow for so long, too, especially given all the folk in the [aca]fandom circuit (myself included) carping loudly about publishers failing to embrace new platforms and technologies. The sheer joined-up-ness of this project (and the decision to base it all on pure HTML5, with no flash-in-the-pan walled-garden proprietary app crapola) is ambitious and forward-looking; I’m sure there’ll be some minor snags here and there, but I get the sense that this has been thought through very carefully, and that a certain allowance for tweaking and flex has been built in.

And to see that vast (and apparently set-to-grow) backlist of out-of-print titles brought back into availability is a thing of wonder. Ladies and gentlemen of Gollancz, and everyone else who has been involved: I salute you.

Blood sugar tech’s magic

Medical implants – think pacemakers and the like – are getting more commonplace, and that trend is likely to continue. But as any gadget-hound will know, tech needs juice to keep running… and you don’t really want to have to keep digging out a device from inside your body so you can swap out the batteries, do you? Of course you don’t… which is why the University of Frieburg’s research into biological fuel cells powered by the host’s blood sugar is a promising development.

They are looking into the use noble metal catalysts, such as platinum, to trigger a continuous electrochemical reaction between glucose in the blood and oxygen from the surrounding tissue fluid. The use of platinum (or a similar metal) would be ideal, as the material exhibits long-term stability, it can be sterilized, and electrodes made from it wouldn’t be sensitive to unwanted chemical reactions, including hydrolysis and oxidation.

The Freiburg scientists are ultimately hoping that the surfaces of implants could be covered with a thin coating of the fuel cells, which would then power the devices indefinitely.

Medical uses are all well and good, of course, but there’s a whole bunch of other cyborg gubbins that could use the same power-source. Book your combat hardening and sousveillance countermeasure systems implant appointments today!

Meatpuppet farming: the (dark) grey-hat global freelance job market

Compsec maven Brian Krebs rakes over the findings of University of California, San Diego research report into the online market for what I like to call meatpuppets: cheap human labour-on-the-web that gets leveraged for bypassing the security systems that are supposed to stop automated spammers.

“The availability of this on-demand, for-hire contract market to do just about anything you can think of means it’s very easy for people to innovate around new scams,” said Stefan Savage, a UCSD computer science professor and co-author of the study.

The UCSD team examined almost seven years worth of data from freelancer.com, a popular marketplace for those looking for work. They found that 65-70 percent of the 84,000+ jobs offered for bidding during that time appeared to be for legitimate work such online content creation and Web programming. The remainder centered around four classes of what they termed “dirty” jobs, such as account registration and verification, social network linking (buying friends and followers), search engine optimization, and ad posting and bulk mailing.

“Though not widely appreciated, today there are vibrant markets for such abuse-oriented services,’” the researchers wrote. “In a matter of minutes, one can buy a thousand phone-verified Gmail accounts for $300, or a thousand Facebook ‘friends’ for $26 – all provided using extensive manual labor.”

The evolving marketplace is best illustrated by the market for services that mass-solve CAPTCHAs — those agglomerations of squiggly numbers and letters that webmail providers and forums frequently require users to input before approving new accounts. The researchers found that the market for CAPTCHA-solving was fostered on freelancer, but quickly expanded into custom markets when the model proved profitable on a large scale. Today, there are plenty of commercial services that pay pennies per day to low-wage workers in India and Eastern Europe to solve these puzzles for people wanting to create huge numbers of accounts at one time.

It’s interesting to see massive crowds of human labour getting rolled quite effectively into these vast and largely automated systems: the darkside equivalent of Amazon’s Mechanical Turk, with a smattering of Matrix metaphors on the side. But those digital peons are just trying to make a living, and when you look at the prices being charged for Twitter followers by the thousand and factor in the significant cut being taken by the service aggregators, you realise that they’re probably not making much more than sweatshop wages. Which means that until the massive differential in income between developed and developing nations gets narrower, web security procedures will always be subject to this sort of outsourced brute-forcing. Shorter version: spam ain’t going anywhere anytime soon.

The irony of having blocked five fake Twitter accounts in the time it took me to write this post is palpable. Death, taxes, noise*, spam.

[ * Anyone who’s worked in the recording or music industries will tell you that noise is the third certainty of life. As, I suspect, will anyone who has lived in a block of flats. ]

Not actually “mental time travel” at all, is it?

But it makes for an attention-grabbing skiffy-tastic headline, AMIRITEZ? The actual story here is rather less OMFG: University of Pennsylvania have obtained the first neurobiological evidence in support of the theory of episodic memory.

“Theories of episodic memory suggest that when I remember an event, I retrieve its earlier context and make it part of my present context,” Kahana said.  “When I remember my grandmother, for example, I pull back all sorts of associations of a different time and place in my life; I’m also remembering living in Detroit and her Hungarian cooking. It’s like mental time travel. I jump back in time to the past, but I’m still grounded in the present.”

Jumping back in time to perceptions of the past while still grounded in the present? Strikes me that rewatching old home movies is at least as good a metaphor as time travel, but I’ll grant you that a lot less people would have reported it if it were pitched that way.

Neuroscience is still a fairly new scientific frontier, and while the last decade has seen the arrival of amazing new tools (and enhancements of existing ones), I believe it’s fair to say that these methods are still pretty crude, and the interpretations of results somewhat speculative. But even so, it’s interesting to see these early phases of our attempts to measure something as inherently intangible as the mind:

The memory experiment consisted of patients memorizing lists of 15 unrelated words. After seeing a list of the words in sequence, the subjects were distracted by doing simple arithmetic problems. They were then asked to recall as many words as they could in any order. Their implanted electrodes measured their brain activity at each step, and each subject read and recalled dozens of lists to ensure reliable data.

“By examining the patterns of brain activity recorded from the implanted electrodes,” Manning said, “we can measure when the brain’s activity is similar to a previously recorded pattern. When a patient recalls a word, their brain activity is similar to when they studied the same word.   In addition, the patterns at recall contained traces of other words that were studied prior to the recalled word.”

“What seems to be happening is that when patients recall a word, they bring back not only the thoughts associated with the word itself but also remnants of thoughts associated with other words they studied nearby in time,” he said.

The findings provide a brain-based explanation of a memory phenomenon that people experience every day.

“This is why two friends you met at different points in your life can become linked in your memory,” Kahana said. “Along your autobiographical timeline, contextual associations will exist at every time scale, from experiences that take place over the course of years to experiences that take place over the course of minutes, like studying words on a list.”
