BREAKING SURF US Senate Passes Weakened Anti-Spam Legislation The Controlling the Assault of Non-Solicited Pornography and Marketing (CAN-SPAM) Act, which the US Congress hopes will regulate spam in the US, has been volleyed between the two houses of Congress for a few months. This week, the Senate passed a reconciled version that is expected to pass the House in early December. The President has indicated that he will sign the bill. Although a federal anti-spam law is close to reality, most anti-spam activists are not very happy with the legislation, in large part because it's fairly weak and because it will override much tougher bills that have become law in several states. Direct-marketing associations and large ISPs have heavily influenced the current language of the CAN-SPAM Act. Of course, the bill doesn't become law until the final House vote and a Presidential signature (thanks, Schoolhouse Rock), and there still is some tiny chance that the bill will fail. The law has such a big impact on US anti-spam efforts that we wanted to give you a heads up about it now. CNET has a good summary of the issues.http://news.com.com/2100-1028_3-5111893.html The CBC's "Deadline Iraq" focuses on the international suite of journalists who covered Gulf War II. This incredible documentary first aired Nov. 23, but the CBC will rebroadcast it Nov. 30. If you missed it the first time, catch it the next. If you don't get CBC, try the Web site. It's divided into two primary sections, Stories and Photo Gallery, although there is also an intro page and a list of all interviewees. The gallery is surprisingly tame, but the power of the stories more than compensates. We can't illustrate this any better than to pull a quote from Rob Curtis, a photographer for the Army Times: "You're stepping over dead bodies, you're watching dogs tear intestines out of dead people and you're thinking to yourself that's nature and nature is a cruel bitch. It's one of those situations where you're thankful that you have something other than to think about what you're seeing. You're thinking about the light, you're thinking about the movement, f stops and shutter speeds." http://www.cbc.ca/deadlineiraq/ Why the August Blackout Happened After the massive power blackout Aug. 14 affected 50 million people in eight states and the province of Ontario, President George Bush and Prime Minister Jean Chretien appointed a joint task force to find out why it happened and how to stop its happening again. The North American Electric Reliability Council (NERC) provides the Nov. 19 interim report of that task force, as a PDF and as a PowerPoint summary, along with other relevant material. The report is a powerful document, copiously illustrated and presented in electrifying detail, with 134 pages in eight chapters, four appendices, and glossaries. It paints a vivid picture of a huge, complex machine, the wonder of which isn't that it failed so spectacularly but that it works so well almost all the time. The report blames the August cascade of failure on a series of specific deficiencies in practices, equipment, and decisions, most by Ohio's FirstEnergy Corporation. It pokes into every twist of the system, examines every event preceding the final failure, and compares this blackout with previous ones. The report is a fascinating, at times complicated, document, upon which you may reflect the next time you flip that light switch.http://www.nerc.com/~filez/blackout.html The Impact of the Blackout on the Net The August power blackout affected millions of people in many ways and clearly disrupted Net service in major portions of the US and Canada. Researchers at Renesys have put together a report that quantifies the impact of the blackout on the Net. Out of some 9,700 public networks in the blackout area, more than 2,000 networks suffered severe connectivity outages longer than four hours, and over 1,400 networks were out longer than 12 hours - some for more than 48 hours. Nearly 50% of major Net routing organizations lost connectivity to some or all of their networks in the affected area. Renesys has a summary, but the report itself has more statistics and graphs.Renesys: http://www.renesys.com/news/index.html Report: http://www.renesys.com/news/2003-11-21/Renesys_BlackoutReport.pdf Web sites cited in scientific research sometimes disappear and, worryingly, the rate of disappearance is climbing. As part of its reporting, the Washington Post interviewed Robert Dellavalle, a research dermatologist who investigated the phenomenon and published the result in Science. Pages abandon URLs as a results of Web site reorganization or because they really do disappear from the Web. The problem isn't confined to scientific literature, as sites cited in high school curricula and computing journals vanish at even higher rates. One estimate posits that a quarter of all the British government's pages change URLs each year. Why is this a problem? Most of the time, a drifting page is only an inconvenience, but sometimes important information exists only online - take the British government's dossier on Iraqi weapons as an example. Archives help, but the sheer amount of information that appears each day is overwhelming; each month, new material matches the Library of Congress in quantity, if not quality. http://www.washingtonpost.com/wp-dyn/articles/A8730-2003Nov23.html Vivendi Universal to Pull Plug on MP3.com's Content Some time ago, Vivendi Universal (VU) acquired MP3.com lock, stock, and barrel: the domain name, the site, and the music. Last week, in a confusing piece of corporate wheeling and dealing, CNET bought the domain name but not the music contents which remain with VU. It's not as if VU wants to keep the music - in fact, the company has warned anyone who stores music on the site to find alternative arrangements because it intends to delete the site and soon. MP3.com founder Mike Robertson (yeah, the Lindows guy) is leading the outcry against deletion and the destruction of more than a million songs, many stored nowhere else. Robertson and others have suggested that the Internet Archive could archive the huge online library but VU has refused to permit that. Maybe the company doesn't want all that indie stuff vying with its own products for music-lovers' attention. Maybe Robertson should have thought about this before he pocketed his $100 million plus from the sale of MP3.com. The Register flails at CNET in one treatment of the story and reports on the Internet Archive's willingness to step up in another, while CNET pledges to have a service similar to the old MP3.com site up and running in the new year.MP3.com: http://www.mp3.com/ Robertson: http://www.lindows.com/lindows_michaelsminutes_archives.php?id=90 Register 1: http://www.theregister.co.uk/content/7/34009.html Register 2: http://www.theregister.co.uk/content/7/34143.html CNET: http://news.com.com/2100-1027-5112020.html Internet Archive: http://archive.org/ Rolling Stone on the Top 500 Albums and Iggy Pop Rolling Stone presents what it considers the 500 greatest albums of all time. This seems a bit premature, as time, to all appearances, is rolling merrily along. Perhaps it means to describe the greatest albums to date. Coming in at number one is the Beatles' "Sgt. Pepper's Lonely Hearts Club Band". In fact, the Beatles garner four of the top ten positions on the list, so you know the direction this thing's going. Also in the top ten are Bob Dylan twice and the Rolling Stones, Beach Boys, Marvin Gaye, and the Clash with one apiece. Only 490 to go. You'll find a lot to disagree with, here. You should also read Rolling Stone's super story on Iggy Pop, the 56-year-old who really ought to be dead given his former lifestyle. His credited influences include the Clash, Culture Club, and Snoop Dogg - quite a mix. Clearly, the man combined his apparent death-wish with genius. You may disagree with the Rolling Stone's idea of who's done the best albums, but you can't argue with the reporting on Iggy Pop. At once gross and grizzled, it's a story you won't stop midway through.Top 500: http://www.rollingstone.com/features/coverstory/featuregen.asp?pid=2125 Iggy Pop: http://www.rollingstone.com/features/featuregen.asp?pid=2158 Are Turkey the country and turkey the poultry linguistically related? As you might guess, yes, they are. The Portuguese transported the birds, Meleagris gallopavo, from the New World to their colony in Goa, India. From there, breeders took stocks to Egypt, then under the Ottoman Turks. Trade took the bird to England, where the name "turkey" applied to its Ottoman Turk immediate origin. This story also explains why the bird is called "dinde" in French and "hindi" in Turkish (both mean "of India"), and how the Pilgrims knew what to shoot when they got to the New World. The description is accurate, although you may want to replace Portuguese with the Spanish and M. gallopavo with Numida meleagris (Guinea fowl).... Check out the Straight Dope and Essays on Central Asia for the head-spinning versions of the origin. Just make sure to visit the Patuxent Wildlife Research Center's (PWRC) turkey pages if you go hunting this season, so you don't bag a chicken or a parrot. Chances are, you won't bag a wild turkey, either, but at least you'll know what one looks like. On the off chance you do bag a bird, you may want recipes. We found 237 turkey recipes, from basic to exotic, at RecipeSource. They probably work just as well with chicken, or your neighbor's parrot.

For commercial sites, such strategies are worth real money, and when money is involved, people get creative. Many dubious sites would artificially boost their ranking - based on links to them - with link farms or link exchanges. In many cases, the search phrases used to boost rankings had nothing to do with the Web sites exploiting them. In mid-November, Google changed its ranking algorithms and people who track this kind of thing noticed that many commercial search phrases no longer returned the sites they used to. Web sites that had achieved their rank through years of exposure on the Web all of a sudden found themselves far down the list. Search Engine Guide has an article that investigates the change in detail, explores its impact and speculates, sometimes wildly, about the motivation behind it.http://www.searchengineguide.com/lloyd/2003/1125_bl1.html Undersea Cable Failure Impacts European Net Traffic A couple of breaks in an important telecommunications link point out how dependent the Net is on the fiber cables that girdle the globe. The disrupted cable system is TAT-14, a bundle of fiber-optic strands that connects the US, Denmark, Germany, the Netherlands, France and the UK in a ring configuration. This week, a break occurred in the link between France and the Netherlands. With continual two-way connectivity, a ring should not be interrupted by a single break - and so it wasn't. The problem is that an earlier fault near the US coast made this new break fatal. Ships are being dispatched to fix both breaks. The disruption mainly impacted Europe. A representative from the London Internet Exchange, which carries nearly all UK traffic and over half of Europe's Net traffic, said the company saw a drop in traffic of some 2 GB/sec (normal peak traffic is 32 GB/sec). At press time, the TAT-14 Web site was down, but KDDI Submarine Cable Systems offers a map of the cable. ZDNet UK has more. TAT-14: https://www.tat-14.com/KDDI: http://www.kddiscs.co.jp/e/business/02_15.html ZDNet UK: http://news.zdnet.co.uk/0,39020330,39118125,00.htm Victoria's Secret Fashion Show Ever since its first netcast caused massive traffic jams, the release of "Victoria's Secret Fashion Show" footage on the Web has been something of an event. It's somewhat surprising given the availability of online porn that watching supermodels with attitude sashaying around in wispy bits of clothing designed to titillate is so popular. Regardless, it's that time of year again, and last week's show is now online. There is the video of the show itself, the requisite photo galleries, and some snapshots from backstage (no, no naked pics). Musical guests were Sting and Mary J. Blige - a couple of their songs are available for download. If you give Victoria's Secret your e-mail address, you can also gain access to some extra footage.http://www2.victoriassecret.com/fashionshow/ Retooling Slashdot with Web Standards Slashdot is one of the oldest geek community sites, designed before the age of CSS, XML, and all those other page-layout standards. The distinctive and widely copied look of Slashdot is all done in HTML 3.2 and is heavily based on tables, and some of it is not strictly valid, but it works with early versions of Internet Explorer and Netscape Navigator. Daniel Frommelt decided to investigate what it would take to bring Slashdot into the 21st century with more modern page-layout practices. He captured the Slashdot home page on June 22 and proceeded to convert it into XHTML 1.0 and CSS markup. Were Slashdot to adopt his redesign, it would see significant bandwidth savings, something on the order of 10 GB of bandwidth daily. Read about the project and check out Slashdot itself for comments on the process.Frommelt: http://www.alistapart.com/articles/slashdot/ Slashdot: http://developers.slashdot.org/article.pl?sid=03/11/21/2223256 Publishers Invest in Social Network Service Tribe.net One of the newest social-networking Web sites is Tribe.net, with some 48,000 users signed up since it launched last summer. Tribe.net competes with the well known Friendster service, which offers similar methods of hooking up with friends of friends or people with similar interests. This week, Tribe.net received a large infusion of cash from two big publishing companies, Washington Post and Knight-Ridder. The companies see Tribe.net's technology as an indispensable tool for enhancing their classifieds listings. The idea is to add social networking and recommendations features to classifieds, thus inspiring consumer loyalty to what is traditionally one of the major moneymakers in a newspaper. CNET has details of the cash deal and some quotes from the publishers.Tribe.net: http://tribe.net/ CNET: http://news.com.com/2100-1024-5111924.html Internet Grows in China: The Numbers China is now second only to the US in the number of Internet users. A new Markle Foundation study, based on more than 2,000 interviews, finds that market competition and government policy are promoting this massive growth in Chinese Internet usage. The foundation has supplied a press release and, on its home page, links to the full report. Apparently, market forces and government support can work together to promote technological change. The report points out that there is still room for immense growth.Press release: http://www.markle.org/news/_news_pressrelease_111303.stm Markle Foundation: http://www.markle.org/ AT&T Sues eBay for Patent Infringement AT&T began its Thanksgiving celebrations a week early with shots fired at what it considers to be two turkeys. AT&T filed suits against eBay and subsidiary PayPal for alleged infringement on a patent that the telco holds. This is just the latest in a series of suits filed against eBay and its subsidiaries. Six months ago, a court found eBay guilty of infringing on a patent for the "Buy It Now" concept and implementation, although this decision is currently on appeal. PayPal, which eBay acquired last year, has been involved in several patent infringement suits - at least one of which is still pending. CNET has a brief story.http://news.com.com/2100-1032_3-5110038.html ONLINE CULTURE You have the chance to build a state-of-the-art online betting system, with end-to-end encryption, offshore data warehousing, and voice over IP. Would you pass it up just because the business is illegal and your bosses crooks? Wired has the supposedly true story - as told to Simson Garfinkel, who is not the sysadmin protagonist - of what it's like to work as a techie for an illegal bookie operation. The tale reveals a situation far from the gangster glamour of "The Sopranos" and "GoodFellas". In the hacker's view, the gambling operation is just a normal business that provides a service customers are willing to pay for, with nary a leg-breaking thug in sight. Apparently, an illegal sports-betting operation depends heavily on trust and is far from a windfall as it gives players better odds than many legitimate gambling operations. If a customer doesn't pay up, he must face a collector with a payment plan - and if that doesn't work, the bookies spread the word that your credit is mud. This anonymous hacker obviously enjoyed transforming the work environment from one of clunky computers, antiquated telephones, and paper records into something more technical. He also likes the people he works for, and appreciates operating underground even if there's probably no health insurance or pension plan.http://www.wired.com/wired/archive/11.12/mafia.html Has a stranger come up and offered you the opportunity to jack into their iPod? This article in Wired reports a startling new development in which complete strangers allow fellow iPodpeople to listen to their music. Although the article makes it clear that this iPod-jacking is clearly a new, and limited, phenomenon, think about the implications. By their music devices you shall know them? Besides brief flings of such direct music sharing, iPodpeople can also share playlists, and as a result, a new form of discrimination is appearing on college campuses - playlistism. If your playlist isn't cool, your friends will distance themselves from you - and if your list is cool, people will be quick to copy it. Apple's little device is more than a beautiful design; it might yet become an instrument of social change. Whatever will the RIAA do once people start sharing wirelessly? iPod-jacking: http://www.wired.com/news/mac/0,2125,61242,00.html Playlistism: http://www.wired.com/news/mac/0,2125,61177,00.html If you have been reading NSD regularly, you probably have your own list of the top ten Internet fads. We thought blogs would have to be high on the list, but this humorous discussion on Kuro5hin makes it clear that we have been looking in the wrong place. However, how many people really remember PointCast? Be sure to read the comments that follow the article; some people really do have long memories. http://www.kuro5hin.org/story/2003/11/14/173126/56 ONLINE TRAVEL Skyhigh Airlines isn't a real airline, but you'll certainly recognize many of its strong points in the airlines you've flown. The Skyhigh site may remind you of the site of one particular airline, but there are echoes of all here. Skyhigh's Web site believes in total honesty. Its seat-assignment plan is called Challenge Seating and it makes sure you get the seat you deserve and can hold onto; the online baggage tracking system is plainly called the Global Baggage Tracker. Classes of seating are not the so-called first class and coach, but bench and cargo. Passengers relate to that sort of truthfulness. Be sure to try out the reservation system. The results are eye-popping.http://www.skyhighairlines.com/main.asp ARTS & ENTERTAINMENT Perhaps the ultimate challenge for a filmmaker is the short short. For some, it's a TV ad. For those who entered the Bristol-based DepicT! Short Film Competition 2003, it's a film no longer than 90 seconds. The competition's Web site reproduces the top entries as QuickTime downloads in three screen sizes, the largest of which is 480 pixels wide. "Le Cheval 2.1" won the GBP3,000 prize, somehow beating out our favorite, "How to Tell When a Relationship is Over". The 15 finalists are all British. Humor, special effects and surprise are common to most. "My Insane Sister" and "The Commuter" are weird, "Moment#3" and "Squish" are amusing. Our reviewer considers the surprise-ending genre best represented by "Squish" and "Sick". You can also view winners and runners-up from 1999 to 2002. On with the show!http://www.depict.org/ Where can you see Batman, the Wheel of Fortune, and the Titanic all in the same place? These elements of pop culture can be seen in "The Picture of Everything" by Howard Hallis. This ambitious piece depicts thousands of prominent icons from past and present. You'll discover such characters as the Nestle Quik rabbit, Mary Poppins, and Wierd Al Yankovic. You'll also find noteworthy places such as the Emerald City, the Addams Family house, and Candy Land. View this work of art in its entirety, and then explore the piece more thoroughly. You're sure to discover strange creatures, hidden surprises, and intriguing curiosities. Further examination of this site produces even more odd masterpieces created by Hallis, including the melancholic and zany "Wrong Dimension Boy". We'll give away a free year of fine NSD products to the first person who e-mails us to tell us where we can find Waldo in "The Picture of Everything". http://www.thepictureofeverything.com/ This site lends credence to the aphorism that says you can't make a sculpture without carving a few eggs. Come here to discover the delicate handiwork of master sculptor Al Gunther. He carves his elegant pieces from the dainty shells of eggs. You can view several examples of his work in his online sculpting and carving galleries. Here you'll discover the intricate details of roses, doves, and angels gracefully personified in fragile eggshell. Further exploration of the FAQ yields a description of the process Gunther uses to carve eggshells. Details on the types of egg shells used for carving are also available. With the holidays fast approaching, this artwork is the perfect one-of-a-kind gift for that hard-to-buy-for person. Prices range from a few dozens of dollars to nearly $1,000. Choose from one of the many designs shown on this site or custom design your own. http://www.webcom.com/24k/eggsculpture/welcome.html Every once in a while you'll find a site so well done that you have a hard time telling whether it is serious or not. This Web site devoted to ornithological dejecta art is not, but it is highly entertaining. The history of this art movement is explained in the World of Bird Art section, and we learn here that these works are beginning to command high prices among collectors. There is also something here for the budding bird-splay artist, as tips for collecting splay from your windshield are given - something you might want to think about as the dejecta of a blue winged teal recently fetched $6,000 at auction. The centerpiece of the site is the Gallery that currently houses a collection of the mounted guano of British and European birds, though a North American bird-poop collection is planned. Each exhibit has its own catalogue entry that details where the splay was collected together with the weather conditions at the time and a description of the fecal matter. This fine site comes from the folks at the Museum of Non Primate Art, whose sites we first started covering in NSD 2.07. Bird Art: http://www.monpa.com/ba/index.html NSD 2.07: http://www.netsurf.com/nsd/sub/v02/nsd.96.03.07.html#AO1 How well do you remember '80s song lyrics?

The creator of this quiz has a refreshing sense of humor that adds to the site. http://www.yetanotherdot.com/asp/80s.html And Now for Something Completely Disney Disney's timeless animation has enchanted millions for decades. Among the enchanted Disney fanatics, one man stands out from the throng. George C. Reiger Jr., owner of the aptly titled DisneyTattooGuy.com, easily secures the a nomination as one of the biggest Disney fans. Reiger has more than 1,500 Disney images tattooed onto 85% of his body. He has spent 20 years pursuing his dream of creating a living canvass dedicated to Disney animation and we hope - we really, really hope - he never loses a copyright suit. In addition to his body art, Reiger has also completed a custom home with custom Disney features and has adorned it with over 15,000 Disney collectibles. Browse photographs of Reiger's tattoos and home at the picture gallery available on his site. Also check out his Top 10 List page, which highlights some of reasons why he considers himself Disney's number one fan.http://www.disneytattooguy.com/ BOOKS & E-ZINES
The Chap Presents Trouser Semaphore The Chap Magazine was founded in 1998 by a pair of rum coves (a practically untranslatable English expression from a lost era, meaning something like "fine fellows") and is a haven of refinement for the discerning English gentleman. It is a manifesto of sorts, with the aim of promoting the lost arts of insouciant dandyism, elan, and panache in these vulgar times. Understandably, modern modes of communication such as cellphones and e-mail are viewed with undisguised horror, and the whole of the internet itself is seen as distinctly brutish. Still, these rum coves have taken to the Internet, if not wholeheartedly embraced it, with a view to promoting their values, and here they propose an elegant form of communication known as Trouser Semaphore. They provide a brief lesson in the rudiments of conveying your innermost thoughts to likeminded individuals "using nothing more than flexibility of your physique and the rough pliability of one's trouser cloth." There is even a demonstration of the art in Flash, which comes across as the animated equivalent of a finely tooled Moroccan-leather-bound slim volume.The Chap Magazine: http://www.thechapmagazine.com/ Trouser Semaphore: http://www.thechapmagazine.com/Trousers/semaphore.html Someone at Cornell University is thinking. What better way to attract contributions and applicants than a slick multimedia showcase on the Web? Explore Cornell is an e-zine that highlights the school's research, instruction, and facilities. There are also virtual campus tours, of course. These are extensive, with virtual panoramas, aerial photos, and narrated QuickTime videos of sites and landmarks. The main attractions here are topical features with wide appeal. 3D Body Scanner shows how Cornell researchers study clothing design and fit with virtual try-ons like those in use at Land's End and other retailers. Cornell predicts that tomorrow's clothes will be made with mass customization instead of mass production. The large section on home gardening, based on the university's research and outreach in agriculture, also tugs at the consumer in all of us. The neat stuff there includes an interactive guide to growing flowers and vegetables (check off hardiness zone, deer resistance, bloom time, etc.), a calendar and tips for lawn care, and a guide to designing flower gardens that includes a ten-page introduction to color. Explore Cornell makes us wonder how soon other universities will try to outdo this splendid work of public relations. http://explore.cornell.edu/index.cfm Baconizing Amazon.com's Suggested Items You may have noticed, as you've been browsing Amazon.com, that the site tells you that "Customers who bought this title also bought:", followed by a list of titles. Once an author or artist reaches a certain point in sales, Amazon.com's software publicizes those authors or artists most closely associated with them. For example, people who buy Jimi Hendrix's Are You Experienced also tend to buy music from Led Zeppelin and Cream. The Baconizer, named after a game in which participants attempt to connect Kevin Bacon to any actor through shared film credits, follows these Amazon.com links and connects them. So, for example, you type Ann Coulter's "Treason: Liberal Treachery from the Cold War to the War on Terrorism" into the starting item box and Al Franken's "Lies and the Lying Liars Who Tell Them: A Fair and Balanced Look at the Right" in the ending item box and the Baconizer ferrets out how customer purchasing patterns link these books at Amazon.com (five jumps, by the way). The results of your Baconizing will range from pretty obvious to absolutely amazing with all shades in between. The random walks are a hoot.http://www.baconizer.com/ "The Time Has Come", the Walrus Said, "Eh?" The Walrus has hauled out on the shores of Canada with high hopes of becoming the Great White North's answer to American publications such as the Atlantic and the New Yorker. Excerpts from the first issue show a great deal of promise, and include such diverse topics as the effect of Arnold Schwarzenegger's election upon national politics in the US, a snapshot of the inhabitants of the Congo (including the elusive Bonobo), and a characterization of Moscow as the "City of Lost Children". It makes for powerful reading, and you may want to subscribe to the print mag after your visit.http://walrusmagazine.ca/ SURFING SCIENCE Estimating the Airspeed Velocity of an Unladen Swallow Jonathan Corum finally answers the question posed by the keeper of the Bridge of Death to King Arthur in the famous sequence from "Monty Python and the Holy Grail". Actually, Corum doesn't answer the question definitively since the relevant data about swallow flight dynamics is somewhat sparse. Instead, he provides scientific estimates based on bird flight theory and data from birds of comparable mass and size. And, yes, if you're wondering, there actually is wind tunnel data on swallows. As an added bonus, Corum also gives you the capital of Assyria - the answer to another trick question from the scene. Slashdot has noted the study with the usual enlightened discussion. When asked by the Slashdot crowd "Tell me again how sheeps bladders can be used to prevent earthquakes," Corum answers, "I am but one man, sir."Unladen Swallow: http://www.style.org/unladenswallow/ Bridge of Death: http://www.mwscomp.com/movies/grail/grail-23.htm Slashdot: http://science.slashdot.org/science/03/11/19/009201.shtml Terrorist attack may be the latest threat to landmarks, but time has defaced landmarks since humans raised their first. Rain, wind, and corrosion are but three enemies of monuments to human achievement. Pierre Roberge, professor of materials and corrosion engineering at the Royal Military College of Canada, maintains his site, Corrosion of Historical Landmarks, in the belief that public landmarks have intrinsic value and that we should therefore preserve them. He lists many historical landmarks significant in engineering. Most visitors will recognize only a few of them (do Tredegar Iron Works and Polymeric Materials Laboratory ring a bell with you?) and may skip the list along with the extensive academic section on corrosion monitoring. The more popular feature is Roberge's focus on recognizable landmarks such as Christ the Redeemer, the Colossus of Rhodes, and Statue of Liberty. Some of the historical details may surprise, if not rivet, you. We learned that the Colossus of Rhodes, one of the Seven Wonders of the World, "stood for only a little more than 50 years before it was destroyed in an earthquake and laid with his face in the sand for centuries after." There aren't many illustrations here, either, or links to offsite references. Maybe it's enough to understand that, for all our efforts to inspect and control, stone and iron and concrete are transient after all. http://www.corrosion-doctors.org/Landmarks/Frames.htm You've heard of the Atkins diet, but there's a different take to be found: geeks look at it as body-reengineering. Salon reports that some hackers adopt the low-carb diet as an extension of the basic hacker philosophy - reprogramming so that the system performs in the way the hacker wants it to perform. In this case, it's not chips and silicon, but the bag of carbon-based cells that comprise their bodies. It seems hard to believe, but the regulation diet of cans of soda and bags of chips may be falling out of favor among hardcore coders. If so, it changes the entire coding paradigm. We can only hope that it leads to a trend toward bug-resistant coding as well. http://www.salon.com/tech/feature/2003/10/30/low_carb_hackers/index_np.html SOFTWARE Emulator Compares P2P Algorithms Since so many people are developing peer-to-peer (P2P) applications these days, researchers have developed p2psim software, which helps debug and compare the performance of those applications. To quote the Web site: "p2psim is a free, multi-threaded, discrete event simulator to evaluate, investigate, and explore peer-to-peer (p2p) protocols". It runs on Linux and FreeBSD. It already supports several different P2P protocols written in easy to comprehend pseudocode. The program is part of the larger Infrastructure for Resilient Internet Systems (IRIS) project, which is developing a decentralized programming infrastructure based on distributed hash tables.p2psim: http://www.pdos.lcs.mit.edu/p2psim/ IRIS: http://project-iris.net/ |
