An anonymous reader quotes a report from TechCrunch: Research scientists at Queen's University's Human Media Lab have built a prototype touchscreen device that's neither smartphone nor tablet but kind of both -- and more besides. The device, which they've christened the MagicScroll, is inspired by ancient (papyrus/paper/parchment) scrolls so it takes a rolled-up, cylindrical form factor -- enabled by a flexible 7.5inch touchscreen housed in the casing. This novel form factor, which they made using 3D printing, means the device can be used like an erstwhile Rolodex (remember those?!) for flipping through on-screen contacts quickly by turning a physical rotary wheel built into the edge of the device. (They've actually added one on each end.) Then, when more information or a deeper dive is required, the user is able to pop the screen out of the casing to expand the visible display real estate. The flexible screen on the prototype has a resolution of 2K. So more mid-tier mobile phone of yore than crisp iPhone Retina display at this nascent stage. The scientists also reckon the scroll form factor offers a pleasing ergonomically option for making actual phone calls too, given that a rolled up scroll can sit snugly against the face. The team posted a video showing the prototype in action. They will be presenting the project at the MobileHCI conference on Human-Computer Interaction in Barcelona next month.

The new "biotic revenge hypothesis" suggests that dinosaurs were killed off by toxic plants. (And an inability to recognize the taste of a toxic plant.) the gmr summarizes a new paper reported at Phys.org: The dinosaur population had been drastically decreasing before the asteroid impact, [and] the appearance of the first flowering plants -- angiosperms -- in the fossil record coincides with the gradual disappearance of the dinosaurs... The scientists concluded that though the asteroid played a role in the extinction of dinosaurs, the "plants had already placed severe strain on the species."
Crocodiles (believed to be descended from dinosaurs) also can't recognize the taste of toxic plants -- the researchers tested 10 different species. And they point out that not only did dinosaurs start to disappear before the asteroid impact -- they continued to "gradually disappear for millions of years afterward."

codegen writes "The Ontario Court of Appeal has just ruled that the police can search your cellphone if you are arrested without a warrant if it is not password protected. But the ruling also stated that if it is password protected, then the police need a warrant. Previous to this case there was no decision on if the police could search your phone without a warrant in Canada."

dsmith3689 writes "Researchers at Queen's University in Kingston, Ontario have explored the use of an eye tracker as a control device for a handful of commercial video games. To do this, they integrated a Tobii 1750 desktop eye tracker with Quake 2, Neverwinter Nights, and a flash adaptation of Missile Command called Lunar Command. A study was performed that indicates the use of direct feedback from eye movements can drastically increase the feeling of immersion (pdf) in the virtual world."

Slashback, below, brings updates and followups to several recent Slashdot stories, including Diebold's (trivial) financial penalty for copyright abuse, reviews of 'The Last Starfighter,' an inquiry into the best response to the recent seizure of Indymedia's servers in the UK, and the upcoming, distributed Mozparty2 to celebrate the 1.0 releases of Firefox and Thunderbird. Read on for the rest.

An apology might be a nice start. Chris writes "The UK government has broken its silence on the Indymedia server raid and is claiming that there 'no UK law enforcement agencies were involved'; see Richard Allan's blog for the whole written answer. This means that the potential for taking legal action against Rackspace in the UK needs to be explored -- were any UK laws (eg the Data Protection Act 1984 or the Regulation of Investigatory Powers Act 2000) broken? Are there any UK cyber law experts on Slashdot with any suggestions...?"

Is Google private enough for you? XeRXeS-TCN writes "Following on from the recent concerns reported on Slashdot about the Google Desktop, the CEO of Copernic has warned about user privacy. Google Desktop Search allows users to opt out of sending the company back detailed usage data, but it isn't possible to firewall it completely. Much more ominously, Google's product manager Marissa Mayer said she expected the private queries to generate more hits for google.com. Most people, she believed, would choose to combine personal and web searches resulting in more revenue for Google's ad business. More on this at The Reg."

If this is a dupe, then Murphy was right. Vcullen writes "The Formula that scientists recently proposed to calculate Murphy's Law has recently been turned into an easy to use online Murphy's Law calculator. So now you can work out what the probability of it happening on any given situation!"

The world's first pool-playing robot consists of a slim box that glides along tracks above a pool table, and shoots using a camera-guided cue. Deep Green pots only half the shots it plans for - supposedly the same as a below average player - but this is expected to improve."

Although this area has been studied, and non-commercial refactoring tools for C++ exist, how comfortable are people using an automated solution for refactoring with this particular language?"

Vagary asks: "There have been quite a few discussions about becoming a system or network administrator or developer, but in light of recent outsourcing trends it seems prudent to aim for something a little less expendable. What is the ideal education (eg: Master's in CS, MBA in Tech Management?) and entry-level career path (in light of today's job market) to become upper-level IT management such as a CIO or CTO?"

Tonight's Slashback arrives with updates on disappeared Intel contractor Mike Hawash, free Baen books, a new link for comparing space ship sizes, and more. Read on below for the details.

Yes, charges are nice after six weeks of unexplained incarceration. purdue_thor writes "The various news agencies (CNN, FoxNews) are reporting that after being held for six weeks, software engineer Mike Hawash has finally been charged. His detainment as a material witness and subsequent incarceration without formal charges was discussed previously on /. Friends of Mike Hawash have created a website to publicize his case and have released a statement regarding the charges."

Randolpho adds "The Free Mike Hawash website has released the following affidavit (PDF file) received from the Federal Terrorism Task Force. The affidavit states that Hawash traveled to China in 2001 with several co-conspirators 'in an attempt to enter Afghanistan to fight against United States forces.'"

This just in from the cork-topped bottle. danny writes "One of the disadvantages of living in Australia is that my review copies arrive late. But my review of Google Hacks may be of interest, even after honestpuck's earlier review."

Free as in books. Author John F.X. Sundman writes: "PDFs of the complete Acts of the Apostles and Cheap Complex Devices are available for free download from wetmachine.com under the Creative Commons license."

And Robotech_Master writes "Remember the Honor Harrington CD-ROM, which Baen packaged with its most recent Honor Harrington book? The one that included over three dozen e-books and came with explicit permission to copy and share but not sell?

Well, Baen's done it again. The new CD comes with the fourth book in John Ringo's Aldenata trilogy, Hell's Faire . It includes still more free e-books, mp3s, and even a D20 Aldenata roleplaying game in electronic form. The book hits the stands this month, and the ISO is already available on-line. (Scarywater guy, please take note. :) Download it, burn it, give it to your friends...or buy the book and support one of the most Internet-clueful publishers out there today."

Free as in "you pay money." An anonymous reader submits "The original Douglas Adams Hitchhikers Guide to the Galaxy, was first a book, then a radio series. Adams edited both. All 7 hrs and 30 minutes of the Radio series have been released by the BBC in MP3 CD format. If you only caught the TV series this is a must."

I wish more audio books would arrive like this (compressed, so as to occupy fewer disks), though I'd choose a better method of audio compression ;) If you want to hear the HHGttG, though, a few minutes on Google will probably turn up some fan sites with recordings from the BBC broadcasts. (innocent whistling)

Yeah, but there's no Epcot Center. Sacarino writes "Las Vegas is *almost* on par with Disney now. The regularly-updated Monorail Society website has tons of pictures of the progress. Vegas' monorails are the same type as Disney's (Bombardier Mark VI), only with inwardly opening doors... slick! Also mentions the old MGM-Bally's monorail that's getting absorbed into the new automated network."

Is this what Microsoft thinks of viral licensing? Vagary writes "One of my friends just got a Microsoft router and asked me to check the security features for it. The ping denial doesn't work, which is good because a port scan found some pretty interesting things, including this string in the TCP/IP fingerprint: 'i586-pc-linux-gnu'. Does that mean Microsoft must provide Linux source to purchasers of this product?"

Can anyone confirm, deny or explain this interesting claim?

Click here to discuss the size of a fictional spacecraft ... photozz writes "The infamously slashdotted site comparing the relative sizes of several hundred starships from various Sci-Fi series has been mirrored to a somewhat more robust server. So cool. It's in draggable format, so you can put King Kong on top of Deep Space 9 and re-create a dream I had last night......."

0biJon writes "The BBC says 'For as little as $20,000, you could soon have a letter sent to a new "post office" aboard the International Space Station (ISS) and back care of the Russian space agency.' Maybe Lance Bass can mail himself up?"

Henn writes "The BBC is carrying a story about computers that track how much attention you are paying and the "worth" of individual messages. Based on these criterion, it adjusts how intrusive to make the alerts. The story is fairly short, however you can find more depth over here." Interesting ideas, but for me it's becomming less about time- my filters catch 80% of my spam, meaning it only takes me 10-20 minutes to deal with it, and more about bandwidth. At home, on my modem, downloading several megs of spam seriously interferes with my ability to work. Yay spam!

World Solar Challenge pits high school, university, and corporate teams against each other in a race across Australia's Outback, from Darwin to Adelaide." Mdog supplies some more (ahem) non-partisan information about the race below.

"My Alma Mater's team (which took second in the American Solar Challenge...go UMR!) is looking to take sweet revenge on the evil (*g*) that is the U-Michigan Solar Car team (which won ASC.) Some other North American heavyweights will be Queen's University and U-Waterloo from the frigid north. I'll defer to Ozzies post links to their favoUrite college teams, which, along with the Japanese teams, are often very good. Lastly, watch out for team Solar Motions; out for blood after major technical problems two years ago. Their array is worth...how should I put this...a lot :)

I went two years ago, and this year I'll just be looking forward to this article getting posted on /. *sigh* Good luck and good sun to all the teams. No worries!"

DoctorNathaniel writes "The Sudbury Neutrino Observatory has just released it's first results. SNO is basically a big tank of heavy water in a deep, dark mine in Canada that is used to detect particles coming from the sun. This result is very cool to anyone following the the science of neutrino oscillations: the new data goes a step further to proving neutrinos have mass, and that neutrinos from the sun can 'change flavour' into different kinds of neutrino. The data exclude "sterile" solar neutrinos. This data expands and compliments the results announced by Super-Kamiokande in the last few years. My glee in all this is of course partially due to the fact that I'm a collaborator on the SNO project.... a regular 'SNO-flake'."

The SNO Detecter is definitely one of the coolest and most ambitious experiments i've seen in recent years."

Somewhere, there's a member of People for the Ethical Treatment of Insects getting all riled up.

orKiD asks: "Since PDAs are becoming very common in today's world, is there any possibility of a PDA clone? A lot of the computer buying boom was caused by the AT clones that came onto the market. They brought prices down, they let people customize and get exactly what they wanted. This didn't really happen with laptops, so can it, and will it happen with PDAs? If not, perhaps a PDA designed by the people, for the people? An OpenPDA? I am currently contemplating on buying a PDA, and even though many of the PalmOS PDAs are similar, each one has its advantages, and disadvantages. I want to be able to pick and choose exactly what I want in my PDA." Hmmm...interesting thought. Read on for more info...

This question sounds awfully similar to this one from iKev: "Remember the Itsy ? Well, I was browsing the Web page today, and noticed that several movies (.avi and quicktime) exist, that show off the power of this device. There's the infamous Doom in action, java apps, e-mail, and the rock'n'scroll input system. This is not vapourware, its the real deal, so why oh why doesn't Compaq go full scale with this one? Oh, I forgot, they don't cater to the geek crowd. Has anyone been able to build one of these BTW? I would fork out for it in a flash... "

Might this project be an answer to both? Gratis to Tim Lord for the info.

Welcome to the 2nd edition of Slashback, upgrading your Slashdot experience with another week's worth of additions, updates, new links and new thoughts, all for the same low cost. (Read more.)

Like the end credits on a short, short film. gi_wrighty pointed out that "the winners from the 5K web page contest (announced a while back ) have now been announced." Here are the welterweight web winners.

A different kind of Apache Con From Slashdot's own jimjag: "Are you interested in the details concerning how www.apache.org was defaced, as reported right here? Here's how it was done from the definitive source. It just goes to remind all of us that sometimes the obvious things are the ones we don't see, and the ones that come back and bite us in the arse. I can imagine quite a few SysAdmins making some changes over the last 36 hours."

... because the old ones were invidious. Remember the flap over GPL code in non-GPL drivers released by NVidia? Well, happily, the company kept its promises. Kheldar_522 writes "LinuxGames.com is reporting that the new NVIDIA XFree86 4.0 drivers released tonight have had all the GPL code removed."

May the circle be unbroken. Meanwhile, on the other side of the world, instead of subtracting code, Samsung is hoping to make sure some gets added. iKev contributed the news that "Last Sunday, Gmate, the creators of the [Linux-based PDA]Yopy, released a very preliminary SDK for the Yopy. You can check it out here (click on the Developer image). I haven't had a chance to try it (it's only for x86 linux)." iKev wondered whether the terms of the download violate the GPL, which is used for some parts of the SDK. Any takers?

Coupled with some decent mapping software, this might even help me get less lost, more often. Be warned, though -- this is not the only purveyor of Palm maps, and they do want to sell you some.

We han Cardly wait! For those who read paper books, this should be good news, contributed by Anonymous Coward after reading about the new Ender's Game sequel: "In a recent interview on otherview.com, OSC mentioned that he is also working on two more sequels to Ender's Game. Shadow of Death, the "final volume about Bean," and an unnamed Petra-and-Peter book. He mentions this on the third page of this article. Also interesting, OSC apparently is all in favor of e-books, though his publisher won't let him do it."

"Biting into some software and finding half a worm!" It's been a quiet couple of days for the administrators of Windows networks -- unless they have MS Outlook e-mail, in which case they don't feel Loved and it isn't Very Funny. Østergaard writes with "this piece, mainly as a reflection on the current worm mania filling the news (and mail-servers ;) around the world. I'd like to see what you people think." It's good reading, and very sobering if you're running the user agents at fault, or ones that could be, next time 'round.

No Such Agency writes "Wired News reports that Hedy Lamarr has died at the age of 86. Lamarr was not only a sex symbol and film star in the 30's-40's but also invented 'spread-spectrum' or frequency-hopping radio (with composer George Antheil). Originally intended to provide jamming-proof communications and remote torpedo control, the technology is one of the foundations of modern wireless communications, including wireless internet connections and GPS. Unfortunately their innovation was not appreciated until after their patent had expired. You can read more about Lamarr and spread-spectrum radio here."

Dallas-based start-up Media Fusion has won a U.S. patent on a process it says can send data, video and voice over electric wires at speeds thousands of times faster than current high-speed Internet access technologies." They keep on trying. We keep on hoping.

Background

It was in the early nineties when I became interested in these sorts of things. I was enrolled in a commerce program, but somehow got onto reading such popular science books as Levy's Artificial Life: A Report from the Frontier Where Computers Meet Biology and Waldrop's Complexity: The Emerging Science at the Edge of Order and Chaos.

Those books made me make my next degree a computer science degree.

Emergent Computation

I was fascinated by the idea of computation emerging from the bottom up: from simple rules acting together in simple ways. This is in marked contrast to the traditional artificial intelligence view that complex behaviour typically only arises from the top down: from the complex interactions of complex rules.

I could appreciate the uses of traditional AI techniques, but emergent computation seemed somehow right to me.

Genetic Algorithms

Notwithstanding my simplistic explanation, there's an obvious example right in front of us. Evolution is a relatively simple process (everyone's heard of Darwin, right?) that has produced very complex output (e.g. us). What if we could harness the power of this evolutionary computation?

John Holland had the idea of mimicking this process of evolution within the computer. He encoded potential solutions as strings of zeroes and ones (the language of the computer), much as human genotypes consist of DNA strands. He developed these strings into actual solutions and measured their success against a particular problem, much as we might measure our success in life. Then he bred another generation, selecting the best individuals to reproduce ("survival of the fittest"), and applying crossover ("sex") and mutation on the strings for good measure.

That's another simplistic explanation, but as time went on these strings got better and better at solving the problem. And it didn't matter which problem. The same process could be used on almost any problem. He called this process a genetic algorithm ("GA").

An Introduction

This book is a good introduction to that world. The first three chapters present an overview of the field, and illustrate how GAs can be applied both in practical problem solving and in more theoretical research environments.

The author explains some of the history and background of GAs, the biological terminology, and its equivalent GA terminology. She provides examples and uses figures effectively.

The entire book has an "overview" feel to it. It isn't very long, and aims for breadth rather than depth. Mitchell writes with clarity, and is great at explaining the subject matter. It's not a difficult book to read.

Theory and Practice

The next two chapters cover the theory and practice of genetic algorithms. Chapter 4 is the most difficult, as it covers Holland's Schema Theorem and other mathematical and statistical observations. Fortunately, you don't lose much if you gloss over the equations, and they're there if you're into that sort of thing.

Chapter 5 is the fun stuff. Mitchell doesn't provide code, but that's okay because the explanation is lucid and sufficiently detailed to implement in code. She discusses ways of encoding the problem, implementing selection methods and the various genetic operators, and setting the parameters of the GA.

To test this theory and practice, each chapter concludes with thought exercises and computer exercises.

Applicability

Dating from 1996, the book benefits from being relatively up-to-date. It borrows from papers and studies up until then, which you'll recognize if you've browsed through other literature (such as the Santa Fe Institute's Artificial Life Proceedings).

Mitchell does reserve a critical view. She's careful to point out where further study is required, and that's important as this remains a maturing area of computer science. She also points out promising avenues for future study.

Summary

I found this book to be an excellent introduction to the field, even though I'd read articles and papers on GAs beforehand. I'd recommend it to anyone interested in genetic algorithms and ready to go beyond the popular science descriptions, but not yet ready for the hardcore books and not willing to waste time on the poorer quality "GAs made E-Z" books.

Basically, this is an excellent quality "GAs in a Nutshell" book. When you've finished it, you might be interested in Goldberg's Genetic Algorithms in Search, Optimization, and Machine Learning.

The book's official site contains a more detailed table of contents, while Mitchell's book page contains solutions to selected thought exercises, an expanded index, and errata.

There are 2 Slashdot teams, we should probably standardize on one: Slashdot.org and Team Slashdot " I vote for Team Slashdot. Go seek out new intelligence if this rocks your boat better than cracking DES keys.
