Commercial Exoskeletons
FalconZero writes "For those of you with superhuman aspirations, your dream may be a step closer; New Scientist (recently) and the Japan Times (last year) covered Yoshiyuki Sankai's work at the University of Tsukuba in Japan developing powered exoskeletons with commercial versions expected soon costing between $14,000 and $19,000 (£7,500-£10,000). Other work with exoskeletons previously covered here(1), here(2) and here(3)." -
Dell Might do AMD
mboverload writes "In a move that will surely make waves in the industry, Dell's CEO, Kevin Rollins, has said they may provide machines decked out with AMD CPU's if their customers really want them. "We are still looking at AMD; they have fairly good technology," said Rollins. " -
Should Nanotech Be Regulated?
Memorize writes "Josh Wolfe writes an article in Forbes arguing that it is too early to regulate nanotech. Wolfe is worried that the 'green gang' (his term for environmentalists) are going to regulate nanotech out of existence before the technology even works in the lab. It seems like much of the discussion of nanotech is hype, including the potential benefits, such as immortality and the potential dangers such as grey goo. However, nanotech does hold some promise of environmental benefits such as cheap solar power. Are the risks real, and if so, is it worth the risk?" From the article: "There are rumblings that regulations are needed. They say they want to guarantee the safety of the technology and instill confidence in the general public." -
Yahoo! Search Providing Support to Wikipedia
Jamesday writes "Yahoo! Search will also be providing support for Wikipedia. Discussions, started at the same time as the aforementioned Google announcement, have been ongoing with both Yahoo! and Google but only the Google news leaked. It's now more clear why Wikipedia said there was no need to worry about undue influence from any single sponsor." -
The End of Mathematical Proofs by Humans?
vivin writes "I recall how I did a bunch of Mathematical Proofs when I was in high school. In fact, proofs were an important part of Math according to the CBSE curriculum in Indian Schools. We were taught how to analyze complex problems and then break them down into simple (atomic) steps. It is similar to the derivation of a Physics formula. Proofs form a significant part of what Mathematicians do. However, according to this article from the Economist, it seems that the use of computers to generate proofs is causing mathematicians to 're-examine the foundations of their discipline.' However, critics of computer-aided proofs say that the proofs are hard to verify due to the large number of steps and hence, may be inherently flawed. Defenders of the same point out that there are non computer-aided proofs that are also rather large and unverifiable, like the Classification of Simple Finite Groups. Computer-aided proofs have been instrumental in solving some vexing problems like the Four Color Theorem." -

Forty Years of Moore's Law
kjh1 writes "CNET is running a great article on how the past 40 years of integrated chip design and growth has followed [Gordon] Moore's law. The article also discusses how long Moore's law may remain pertinent, as well as new technologies like carbon nanotube transistors, silicon nanowire transistors, molecular crossbars, phase change materials and spintronics. My favorite data point has to be this: in 1965, chips contained about 60 distinct devices; Intel's latest Itanium chip has 1.7 billion transistors!" -
A Plasmonic Revolution for Computer Chips?
Roland Piquepaille writes "Today, we're using basically two ways to move data in our computers: transistors carry small amounts of data and are extremely small, while fiber optic cables can carry huge amounts of data, but are much bigger in size. Now, imagine a single technology combining the advantages of photonics and electronics. This Stanford University report says a new technology can do it: plasmonics. (For more about plasmons, read this Wikipedia article.) Theoretically, it is possible to design plasmonic components with the same materials used today by chipmakers, but with frequencies 100,000 times greater than the ones of current microprocessors. There is still a challenge to solve before getting plasmonic chips. Today, plasmons can only travel a few millimeters before dying, while today's chips are typically about a centimeter across. Read this overview for more details and references about plasmonics, and to discover why it's one possible future for chips' circuitry." -

Scientists Weigh Smallest Mass Ever
PaSTE writes "From the article, 'US scientists have managed to measure the mass of a cluster of xenon atoms at just a few billionths of a trillionth of a gram - or a few zeptograms. The record measurement is in the mass range of individual protein molecules, and the detection was made using sensitive scales developed at Caltech.' Another big leap forward for nanotechnology." -
Britannica Takes Over the Wikimedia Foundation
An anonymous reader writes "The Encyclopaedia Britannica has initiated a "semi-hostile" takeover of Wikipedia. Wikipedia administrators, members of the Wikimedia Board of Trustees, Arbitration Committee members and several other cabalists will receive free access.

Spam Kings
Michael Gracie writes "Spamroll is a recently launched blog and information resource on spam, phishing, and other internet security issues, the purpose of which is to bridge the gap between information and discussion among technical professionals, and that targeted for end users. As part of the research for Spamroll, I picked up Spam Kings - The Real Story Behind the High-Rolling Hucksters Pushing Porn, Pills, and @*#?% Enlargements, written by Brian McWilliams and recently released by O'Reilly. , With Spam Kings, Mr. McWilliams has put together a book suitable for shelving next to The DaVinci Code and the Bat Book (Sendmail 2nd edition, by Brian Costales and Eric Allman). It is a compellingly detailed account of the burgeoning of spam, spammers, their foes, and the intricate community that intertwines them." Read on for Gracie's review. Spam Kings - The Real Story Behind the High-Rolling Hucksters Pushing Porn, Pills, and @*#?% Enlargements author Brian McWilliams pages 333 publisher O'Reilly rating 9 reviewer Michael Gracie ISBN 0596007329 summary Excellent spam history and reference.Spam Kings is a pseudo-chronology of the exploits of the biggest spammers of the late nineties and new millennium, following their trail right down to the lunch menu, with the underworld's anti-spam fighters of the day taking the order. The book details the comings and goings of the likes of Sanford Wallace, an early spam king who claimed constitutional authority to send UCE, up to the present-day powerhouses such as Ron Scelson and Scott Richter, whose wealth and influence keeps the heat off of them. [Though Richter's finally gotten some heat where it counts -Ed.] In between, it runs across characters such as Jason Vale, Thomas Cowles, and Rodona Garst, who have all seen some serious time in court and/or jail for their actions, and some, like Brad Bournival, who tangled with the monster called AOL and is still awaiting his fate, and Karen Hoffman, a one time spam hunter who has turned to "the dark side."
But the real (and underlying) story is about two individuals, Susan Gunn, of NANAE fame, and David Hawke, a former neo-Nazi and notorious spammer who continues to elude the massive AOL lawsuit judgments against him.
The antagonists' and protagonists' paths cross often, but they never seem to directly butt heads. What makes the saga so interesting is that their actions affect each other's lives in profound ways, exemplifying the intensely close-knit nature of the spammer and anti-spam communities that surround them, and sometimes, their disloyalties. Furthermore, the lines between spammer and "anti" sometimes blur beyond natural reason, reflecting the deep knowledge of systems and processes each side attains during their trials and tribulations, and the monetary value of that knowledge in the open (if sometimes seedy) market.
What I found most appealing during the read was the relevancy of events that take place throughout, and the meticulous references to the news of the day. I found myself wondering where I was, how much spam I was getting, and whether I could remember receiving any scurrilous product pitches from the characters within. I am now checking old email archives, just for posterity.
The book ends with an epilogue that outlines what is happening in the spam world, right this very moment. CAN-SPAM doesn't seem to be working, other countries have instituted new laws that are, and people of all shapes and sizes may be complicit in the ongoing problem. The epilogue winds up with a "where are they now" for most of the major characters. Many are retired and/or have moved on to new (but not necessarily unrelated) professions, some are still drowning in legal judgments, while some are...educating your children! But you can be sure others have stepped in to take their places; just check your junk mail folder.
The book also contains an excellent glossary of technical and business terms used throughout. If you are a sys admin who saw the term chickenboner or mainsleaze on a help forum, and are embarrassed to ask what that means, then your bases are covered in this book. If you are a regular everyday email user, and are curious what these "blacklists" and "whitelists" are and what they mean to you, the glossary will again prove very useful during and after your read. The work also contains a deep notes section, which I found extremely helpful -- McWilliams conducted in-depth interviews with many of the characters (and they are characters). And let's not forget the center illustration section, complete with numerous photos of the biggest spammers of all time, at work and at play, as well as some gratuitous mug shots (which I am sure is all you really want to see if you despise spam as much as I do).
I knocked this puppy off in two quiet evenings. While the type is appropriately sized and spaced, and the material not overly technical, what drove me was the fact that the work was a bit of a "page turner" -- I had a hard time putting in down.
In my opinion, Spam Kings is a publication for both the technology/history buff, as well as the everyday email user still wondering where the heck all those Viagra ads in their inboxes really comes from.
Spamroll is the latest creation of Michael Gracie, who thinks spam and phishing represent some of the greatest threats to ecommerce and online world in general.

Longest Chemical Name: 64,060 letters
mycro writes "A new article on Wikipedia shows the longest chemical name, reaching 64,060 letters. Methionylalanylthreonyl...leucine is a chemical name for enaptin, a nuclear envelope protein found in human myocytes and synapses, which is made up of 8,797 amino acids. It is involved in the maintenance of nuclear organization and structural integrity, tethering the cell nucleus to the cytoskeleton by interacting with the nuclear envelope and with F-actin in the cytoplasm." -
New Photovoltaics Made with Titanium Foil
Memorize writes "A company called Daystartech has released a new type of photovoltaic cell which, unlike almost all the cells currently in use, does not silicon. This is based on a thin titanium film. Given the current shortage of solar-grade silicon, and all-time high oil prices, maybe titanium solar panels are here at the right time. The questions are, will they release it as a consumer solar product, and what will be the price per kilowatt hour?" -
History Flow Shows How Wiki Articles Evolve
teslatug writes "IBM has released a preliminary alpha version of its History Flow Visualization Application that shows how collaboratively created documents evolve. The tool is written in Java and it's available for download along with plugins for MoinMoin and MediaWiki.

Web Design Hampers Mobile Internet?
aws910 writes "Reuters is running an article on how flashy web design is impacting the usability of internet-enabled mobile devices, with quotes from Tim Berners-Lee. Although the article is sparse on details, it is an interesting topic for discussion. Having recently bought an internet-enabled cellphone, I can honestly say that most websites are painful to view on a 240x320 screen over a GPRS connection(EVDO is expensive/US-only). Have we moved away from 56K-modem-oriented design, only to be pulled back in that direction?" -
RFID Music Player
frazzydee writes "I know what you're thinking, RFID tags used to play music? Well, it turns out that we don't need to take out our tinfoil hats this time, because it turns out that are some constructive uses for the same RFID tags that we have all come to loathe. Since RFID tags can hold 1 kilobyte of data, somebody who goes by dividuum found that (s)he could use the tags combined with a reader to store and play back music. Dividuum used SID files- the same format used on Commodore 64s- and programmed everything in C. Pictures of the RFID device are available here." -

General Motor's EV1 Electric Cars Scrapped
jangobongo writes "Yesterday, the last of General Motors EV1 electric cars were transported to their final resting place, the GM Desert Proving Grounds in Arizona, for "final disposition," which for most of them means crushing and recycling. The experimental GM cars were originally leased (starting in 1996) to owners in California and Arizona for three years while GM developed electric battery technology, but the expected breakthrough in battery technology failed to materialize. GM spent more than $1 billion developing and marketing the EV1, but concluded that the electric cars would not be profitable. The EV1 program was ended in 2003. Some of the cars were donated to engineering departments of colleges and universities, while others went to museums, including the Smithsonian Institution. Despite protests and petitions, GM would not sell the last available cars to the public due to the lack of replacement parts for repairs, and because of potential liability claims. It's sad to see this chapter on electric cars close." -
Open Species Database Breaks Half-Million Mark
ferienhausversicherung writes "Biologists estimate that about 1.75 million species, from bacteria to blue whales, have already been identified on Earth. But there may be anywhere between 3 million and 12 million more yet to be discovered. An online catalogue of all known life on Earth now has half a million species in its freely available database. Another promising effort is Wikispecies. Started in August 2004, this is an offshoot of the Wikimedia group, whose free online encyclopaedia is constructed by users themselves." (And Wikipedia itself is about to publish its 500,000th English entry -- if you hurry, perhaps it will be yours.) -

IE7 Details Emerge
Varg Vikernes writes "Microsoft Watch has a story about new features we can expect in IE7 (code named 'Rincon') which they gathered through Microsoft's key partners. Apparently we can expect 32 bit PNG support, native IDN support, new functionality that will simplify printing from inside IE and, of course, tabbed browsing. The new browser also will likely include a built-in news aggregator. Apparently an important factor is security." -
'Online Poker' Googlebomb
Philipp Lenssen writes "The blogger community is fighting back, though in ways not everyone may like: they are Googlebombing the Wikipedia page on online poker for the phrase "online poker" to make it rank higher in search engines. "Online poker", along with "Viagra", "mortgage" and "debt", are keywords heavily represented in comment spam, which itself aims to boost the Google ranking for a particular site and phrase. The Wikipedia page is currently third in Google." -

Google Goes to Answers.com
tod_miller writes "Google has changed its definitions link from dictionary.com to answers.com. A google search for juxtaposition shows the effect. What is interesting is that answers.com pulls information from wikipedia.org, which was provided bandwidth by google.com [and now Google is providing a service that will be used worldwide to pull information off Wikipedia]. Aside from having both a dictionary.com and a wikipedia.org search box in FireFox (as well as Google) the definition link on Google is still useful and I regularly check it for obscure uses or exact definitions of words. Now it uses answers.com we do not get all the different forms of the word, but we do get any medical or wikipedic information. Interestingly, answers.com does not use Google AdSense, but commission junction that looks like it. There is no announcement yet from Google of their change." This change took place several weeks ago, as players of e-scrabble and other compulsive word-checkers might have noticed. Update: 03/13 23:20 GMT by T : (Also mentioned in passing last month.)

CeBIT 2005: SLI Shuttle Surfaces

Legal Torrent Sites Help Legitimize BitTorrent
Jeff writes "In today's Seattle Times, technology columnist Paul Andrews highlights how legal torrent sites such as CommonBits may lead to wider adoption and acceptance of BitTorrent. With reports that illegal torrent usage may be more than a third of Internet traffic, sites like LegalTorrents, Torrentocracy, Prodigem and bt.etree may offer a compelling defense to future legal attacks while simultaneously promoting fair use rights. Andrews goes on to argue that the future of television may be no further away than integration of podcasting, RSS, tagging and BlogTorrent." -
The Repercussions of Blogging
hende_jman writes "How much should you be allowed to say in a public blog? There's an article on CNN that looks at different situations in which people have been fired for blogging about their company. The main issue brought seems not to be one of a lack of trust (blogs, after all, are most often public), but rather a lack of policy outlining repercussions for negative blogging about one's company." -
DVHS on a Budget
Kerhop writes "ecoustics.com has an article on how to convert SVHS tapes to work in DVHS recorders which is similar to modifying a floppy drive (like we did years ago) to double the storage. There's two holes on a DVHS cassette and a single hole on the SVHS tape. The hole common to both permits DVHS tapes to handle SVHS signals; the hole unique to DVHS is what we want to focus on. Just cut off the top four to five millimeters of the pin within the recorder itself." -

Hobbit Is A New Species
Migraineman writes "Over the last year or so, archaeologists in Indonesia unearthed skulls and bones from eight proto-humanoids. Critics have claimed the meter-tall specimens were either pygmies or "aberrant individuals with a pathological condition" like microcephaly. A recent article in Science[subscription] rebuffs the critics, and claims that the specimens are actually a new species - Homo floresiensis. There's a summary article over at Nature." -
Double-Slit Experiment in Time, Not Space
TheMatt writes "Thomas Young's double-slit experiment is a classic experiment that helped establish the wave-like nature of light. Since then, it has been done with atoms, buckyballs, and biomolecules. It has even been seen in a single molecule, and the single electron version was voted the most beautiful experiment by Physics World readers (covered previously on Slashdot). Now, PhysicsWeb is reporting that Gerhard Paulus and coworkers have conducted the double-slit experiment using a double-slit in time, not space. The "slit" was a crafted femtosecond pulse consisting of one-and-a-half cycles--say, two maxima and one minima--passed through an argon gas. Each maxima has a probability of ionizing an argon atom and producing an electron. The electrons were accelerated to a detector which observed an interference pattern since the detector had no idea which maximum produced the electron." -
Integrating Agile Development
James Edward Gray II writes "If you've ever wanted to know more about the agile programming methodologies, Integrating Agile Development in the Real World is a fine place to look for the answers to your questions. Various agile methodologies are explained, compared, and contrasted within. A good look is taken at how they work, their strengths and weaknesses, and how they compare to the more traditional approaches of software development. This proves to be a strong introduction and overview to agile programming practices." Read on for the rest of Gray's review. Integrating Agile Development in the Real World author Peter Schuh pages 346 publisher Charles River Media rating 8 reviewer James Edward Gray II ISBN 1584503645 summary An encyclopedia of agile software development practices.The book opens with a couple of chapters exploring exactly what it means to be an agile development team. The author doesn't spoon feed you a definition. Instead, he takes a look at the Manifesto for Agile Software Development and pulls from that a collection of values important to agile software development. A list of agile principles is presented, and each of these aspects is examined from the angle of what it's trying to accomplish and where it can help when building software.
At this point, the book introduces seven methodologies including The Crystal Methodologies, eXtreme Programming, and Scrum. Each approach is defined by their practices and focus. The author does a nice job of telling you where these methodologies excel and even where they don't. The approaches are contrasted, but not with an eye towards finding out who is right and who is wrong. Instead, the author digs for the strengths in each practice.
The next few chapters offer suggestions about what agile practices can do for your development team, and outline how to adopt a few agile practices. This is one of the many places where the book really shines, thanks to its realistic approach. The author knows that not everyone can run out, soak up some eXtreme Programming training, and convert their entire division overnight. If you can, great, but this book is more focused on people who don't meet certain agile requirements and others who just want to test the waters a little. For these groups, there is sensible advice like, "Start by doing X, Y, and Z, because they're great ideas, easy to implement, and will help you a lot." If you like those changes, the author suggests what to try next. Even better, you're told to back away from the changes you don't like, sprinkle in some ideas from other methodologies, and even customize the practices to your needs. That may not be as extreme as some agile developers would prefer you to be, but it is agile programming distilled down to what it can do for you personally. I found that to be a great touch.
With the introduction to this new world of software development covered, the book moves into detailing actual agile practices. Early chapters in this section focus on the programmer, testing, and even the database side of the operation. Later chapters get into management, the project, and an agile development cycle. When a practice is defined, you're warned of prerequisites you should have in place before considering it, offered advice for how to get started with it, and even given a few variations that might work better for your group. I wouldn't say that the detail here is sufficient to teach you all you need to know, instead this section arms you with the knowledge to decide what you should be looking into. To kick-start your research efforts, a practice always ends with a list of further resources, available both online and in print.
The final chapters of the book get more abstract, dealing with customers, communication, and even just people. There's a lot of sound advice hidden away in these pages for some difficult challenges. I personally learned a lot about how agile development deals with customers and I have a few new ideas I'm anxious to try on my clients.
As an added bonus, the book has a very nice layout, filled with intelligent, witty prose and good looking charts. These effects are always subtle but can make a text a lot more approachable. I believe my only complaint was that the author tends to throw around acronyms assuming you know what they stand for. I think he even eventually got around to defining all but a couple, but not always when you first encounter them. A glossary probably could have helped in this case.
In summary, this book is agile programming for everyone. As a one-man operation, common practices like pair programming aren't even an option for me. The author knows that the methodologies aren't one-size-fits-all, and really focus on exactly what they can do for you, whatever your own needs may be. If you don't follow any development strategy (hope that's not true), would like to know more about the agile practices without joining a cult, or even just want to stay sane in your traditional software development company, Integrating Agile Development in the Real World will give you plenty of fresh ideas.

Integrating Agile Development
James Edward Gray II writes "If you've ever wanted to know more about the agile programming methodologies, Integrating Agile Development in the Real World is a fine place to look for the answers to your questions. Various agile methodologies are explained, compared, and contrasted within. A good look is taken at how they work, their strengths and weaknesses, and how they compare to the more traditional approaches of software development. This proves to be a strong introduction and overview to agile programming practices." Read on for the rest of Gray's review. Integrating Agile Development in the Real World author Peter Schuh pages 346 publisher Charles River Media rating 8 reviewer James Edward Gray II ISBN 1584503645 summary An encyclopedia of agile software development practices.The book opens with a couple of chapters exploring exactly what it means to be an agile development team. The author doesn't spoon feed you a definition. Instead, he takes a look at the Manifesto for Agile Software Development and pulls from that a collection of values important to agile software development. A list of agile principles is presented, and each of these aspects is examined from the angle of what it's trying to accomplish and where it can help when building software.
At this point, the book introduces seven methodologies including The Crystal Methodologies, eXtreme Programming, and Scrum. Each approach is defined by their practices and focus. The author does a nice job of telling you where these methodologies excel and even where they don't. The approaches are contrasted, but not with an eye towards finding out who is right and who is wrong. Instead, the author digs for the strengths in each practice.
The next few chapters offer suggestions about what agile practices can do for your development team, and outline how to adopt a few agile practices. This is one of the many places where the book really shines, thanks to its realistic approach. The author knows that not everyone can run out, soak up some eXtreme Programming training, and convert their entire division overnight. If you can, great, but this book is more focused on people who don't meet certain agile requirements and others who just want to test the waters a little. For these groups, there is sensible advice like, "Start by doing X, Y, and Z, because they're great ideas, easy to implement, and will help you a lot." If you like those changes, the author suggests what to try next. Even better, you're told to back away from the changes you don't like, sprinkle in some ideas from other methodologies, and even customize the practices to your needs. That may not be as extreme as some agile developers would prefer you to be, but it is agile programming distilled down to what it can do for you personally. I found that to be a great touch.
With the introduction to this new world of software development covered, the book moves into detailing actual agile practices. Early chapters in this section focus on the programmer, testing, and even the database side of the operation. Later chapters get into management, the project, and an agile development cycle. When a practice is defined, you're warned of prerequisites you should have in place before considering it, offered advice for how to get started with it, and even given a few variations that might work better for your group. I wouldn't say that the detail here is sufficient to teach you all you need to know, instead this section arms you with the knowledge to decide what you should be looking into. To kick-start your research efforts, a practice always ends with a list of further resources, available both online and in print.
The final chapters of the book get more abstract, dealing with customers, communication, and even just people. There's a lot of sound advice hidden away in these pages for some difficult challenges. I personally learned a lot about how agile development deals with customers and I have a few new ideas I'm anxious to try on my clients.
As an added bonus, the book has a very nice layout, filled with intelligent, witty prose and good looking charts. These effects are always subtle but can make a text a lot more approachable. I believe my only complaint was that the author tends to throw around acronyms assuming you know what they stand for. I think he even eventually got around to defining all but a couple, but not always when you first encounter them. A glossary probably could have helped in this case.
In summary, this book is agile programming for everyone. As a one-man operation, common practices like pair programming aren't even an option for me. The author knows that the methodologies aren't one-size-fits-all, and really focus on exactly what they can do for you, whatever your own needs may be.

QA != Testing
gManZboy writes "Original author of Make and IBM Researcher, Stu Feldman has written an overview of what should be (but is sadly perhaps not) familiar ground to many Slashdotters: Quality Assurance. He argues that QA is not equivalent to 'testing', and also addresses the oft-experienced (apparent) conflict between QA-advocates and 'buisiness goals.'"
