Farewell to PDAs, Hello to Smart Phones
Roland Piquepaille writes "Is it time to get rid of your PDA? Apparently yes, according to General Motors, writes Ephraim Schwartz in InfoWorld.The subtitle of this story is pretty clear: "GPS, Java, and push-to-talk give smart phones a clear edge over PDAs." "General Motors announced last week that it will partner with wireless carrier Nextel to use Nextel?s Motorola cell phones with data capabilities to market a field-force management application to its commercial truck fleet customers." GM chose these cell phones because people feel more comfortable with, but also because they can run sophisticated applications. And of course, because they are cheaper than handhelds, both to purchase and to maintain. Check this column for a summary and references." -
Information Obesity
Roland Piquepaille writes "How many phone calls, emails, voicemails, memos or stories do you have to go through every day? Probably more than last year. And probably too much. This article from the Sydney Morning Herald looks at this problem of information overload and how to deal with it. Here is a quick and not well-known fact: Website content management author Gerry McGovern says that something like 70 per cent of most websites goes unread. Despite that, when putting content on the web, "rarely do we ask the question: is anybody interested in reading that?" Good point. Check this column for a summary if you don't have time -- and who has? -- to read the original article." -

Silicon Seduced From Silica
Roland Piquepaille writes "Making silicon is an expensive process, which conventionally involves carbothermal reduction, in which the oxygen is removed from silica by a heterogeneous-homogeneous reaction sequence at approximately 1,700 C. Now, Japanese researchers have developed a new technique which uses electricity to remove the oxygen from silica. Their technique is based on the immersion of silica in a bath of molten calcium chloride salt at 850 C, which should reduce the costs of making silicon -- and other elements, like zirconium. Check this column for a summary or read this article from Nature for additional details." -

Making Change
Roland Piquepaille writes "There are mostly four kinds of coins in circulation in the U.S: 1 cent, 5 cents, 10 cents, and 25 cents. But is it the most efficient way to give back change? This Science News article says that a computer scientist has found an answer. "For the current four-denomination system, [Jeffrey Shallit of the University of Waterloo] found that, on average, a change-maker must return 4.70 coins with every transaction. He discovered two sets of four denominations that minimize the transaction cost. The combination of 1 cent, 5 cents, 18 cents, and 25 cents requires only 3.89 coins in change per transaction, as does the combination of 1 cent, 5 cents, 18 cents, and 29 cents." He also found that change could be done more efficiently in Canada with the introduction of an 83-cent coin and in Europe with the addition of a 1.33- or 1.37-Euro coin. Check this column for more details and references." The paper (postscript) is online. -

Self-Repairing Computers
Roland Piquepaille writes "Our computers are probably 10,000 times faster than they were twenty years ago. But operating them is much more complex. You all have experienced a PC crash or the disappearance of a large Internet site. What to do to improve the situation? This Scientific American article describes a new method called recovery-oriented computing (ROC). ROC is based on four principles: speedy recovery by using what these researchers call micro-rebooting; using better tools to pinpoint problems in multicomponent systems; build an "undo" function (similar to those in word-processing programs) for large computing systems; and injecting test errors to better evaluate systems and train operators. Check this column for more details or read the long and dense original article if you want to know more." -

The Debate about Social Software
Roland Piquepaille writes "Is "social software" the new overhyped buzzword? In an article for the Guardian, Jack Schofield says yes. On the contrary, in Historical Roots of Social Software, Howard Rheingold offers insights about this new phenomenon. And in this Tech Central Station article, Arnold Kling agrees with Rheingold. He thinks that social software is likely to the basis of what could be the next "killer app." Kling says that with social software, the interaction is no longer between you and your computer, but between the groups you belong to and networks of computers. In order to explain the issues, King studies three types of problems that this new kind of software might solve: the matching problem, the issue-resolution problem, and the classroom-management problem. So, is social software hype or reality?" -
Mass Storage Leaves Microchips in the Dust
Roland Piquepaille writes "This article from Wired Magazine looks at storage with a new angle. 'Right now I am sitting in front of a whirring 60-gigabyte hard disk that cost less than $100. Do the math: If back then 10 megabytes cost $1,000, then 60 gigabytes would have cost x, where x = $6,000,000 and "back then" = 18 years ago. I'm sitting in front of $6,000,000 worth of mass storage, measured at mid-1980s prices. We have Moore's law for microprocessors. But who's coined a law for hard disks? In mass storage we have seen a 60,000-fold fall in price -- more than a dozen times the force of Moore's law.' DeLong also looks at a non-distant future when a $100 mass storage device will hold a full terabyte. He also thinks that with disk space becoming cheaper and cheaper, we'll be tempted to archive everything about ourselves, including pictures and videos. This is in fact the goal of the Gordon's Bell project, MyLifeBits. You can learn more about the MyLifeBits project by reading this NewsFactor Network article. Check this column for more details." -

The Interplanetary Internet
Roland Piquepaille writes "This article from SPACE.com about the Interplanetary Internet (IPN) is not science fiction. It is becoming a reality, Rich Gray reports. "The IPN would form a backbone connecting a series of hubs on or around planets, ships, and at other points in space. These hubs would provide high-capacity, high-availability Internet traffic over distances that could stretch up to hundreds of millions of miles." Gray adds that all the planets and satellites in our solar system have already Internet addresses and that NASA is already communicating with its earth-orbiting missions through its internal Deep Space Network. The rest of us will have to wait until at least 2005 when IPN-equipped satellites are launched. Check this column for more details. You also can read a previous Slashdot column on the same subject.

Moving Sensor Data Onto The Internet With SensorML
Roland Piquepaille writes "According to this Sensors article, a new XML encoding scheme may make it possible for you to remotely discover, access, and use real-time data obtained directly from Web-resident sensors, instruments, and imaging devices. By describing sensors using SensorML, anyone can put sensors or sensor data online for others to find and use. And because it's XML-based, it means all this data will easily be searchable. "For example, searching for particular kinds of sensors and data in a particular geographic region, with data collected within a particular time window, will be easy. This has significance for science, environmental monitoring, transportation management, public safety, disaster management, utilities operations, industrial controls, facilities management, and many other activities." In this column, you'll find a summary of the Sensors' story which contains more technical details about the technology. And if you're really interested, please visit the SensorML homepage." -

Indian Scientist's Tool To Map Genes In Demand
Roland Piquepaille writes "On April 15, the Human Genome Project's announced that it had completed the task of sequencing the collection of genes that make up the human code. In fact, only 99.9 per cent of the 3 billion pairs of DNA have been sequenced. How will we find the missing pieces? The Hindu reports that "the biotech community is increasingly turning to Pradeep Kumar Chatterjee, Head of Genomics and Bioinformatics at the Julius L. Chambers Biomedical/Biotechnology Research Institute (BBRI) of North Carolina Central University, U.S." He has perfected a process called "deletion mapping technology" to map genes by checking both the sequence of every DNA pair as well as its position in the strand. This is a powerful tool for those who now want to use the genome map to analyze specific strands of DNA to attack individual diseases. Check this column for more details and discover Chatterjee's future projects." -

NASA Satellite Measures Earth's Carbon Metabolism
Roland Piquepaille writes "To celebrate Earth Day, the NASA Earth Observatory recently revealed global measurements of the Earth's metabolism. 'Combining space-based measurements of a range of plant properties collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) with a suite of other satellite and surface-based measurements, NASA scientists produce composite maps of our world's 'net primary production' every 8 days. This new measurement is called net production because it indicates how much carbon dioxide is taken in by vegetation during photosynthesis minus how much is given off during respiration.' Check this column for a summary including the usefulness of such measurements. You'll also find maps showing the seasonal variation of Earth's net primary production." -

Virtualizing Health And Disease
Roland Piquepaille writes "In "'Dr. Data' Digitizes Medical Care," Karen Southwick says that "David Eddy's Archimedes software dares to turn human heartbeats into the ones and zeros of the digital age -- and, just maybe, the nation's healthcare system on its ear." It sounds pretty ambitious, so let's look at some details. David Eddy has built a complex software program he calls Archimedes, named for the ancient Greek mathematician who boasted he could move the world with a single lever. The software model, for the first time in medical history, uses mathematical algorithms and equations to translate the beat of a heart or the twitch of a muscle into the ones and zeros of the Digital Age, replicating in numbers the behavior of a disease and creating a "virtual reality" in which patients, providers and institutions interact as they would in the real world. Southwick also wrote a companion story, "How Archimedes Works," which gives more technical explanations about this software developed by the Biomathematics Unit of Kaiser Permanente's Care Management Institute. Check this column for a summary of these two articles." -

Gas Goes Solid
Roland Piquepaille writes "This innovation from Japanese researchers can potentially revolutionize the energy distribution sector. Instead of transporting liquid gas, they changed gas into a solid material which is easier, safer and cheaper to distribute. Technology Review has the story. "Rather than extracting methane from hydrates, they want to turn methane into hydrates -- essentially, transforming the colorless and odorless gas into small pellets that can be easily stored, transported, and eventually turned back into natural gas. A few months ago Mitsui, in partnership with Osaka University, opened a demonstration plant near Tokyo to promote the concept and show that it works." Check this column for an analysis." -

Robodex 2003 Shows Robots Ready for Work & Play
Roland Piquepaille writes "Robodex 2003 was held last week in Yokohama, Japan. At this show 38 companies, colleges and other organizations introduced more than 90 different types of robot. Many were designed to handle tasks too dangerous for humans and assist people in their daily lives. In this column, you'll find a selection of articles and short quotes about this trade show which attracted about 70,000 visitors. I also built my own Robodex 2003 Fashion Show (the whole page weighs 172KB). You'll find there pictures of many new robots, including Banryu, developed by Tmsuk, Inc., which will control your home while you're away, Doki, the world's first gender-aware robot, built by Intelligent Earth, from Scotland, or the Comet III, a one ton mine-clearance robot from Chiba University.

Can Your PC Become Neurotic?
Roland Piquepaille writes "This article starts with a quote from Douglas Adams: 'The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair.' It is true that machines are becoming more complex and 'intelligent' everyday. Does this mean that they can exhibit unpredictable behavior like HAL, the supercomputer in '2001: A Space Odyssey'? Do we have to fear our PCs? A recent book by Thomas M. Georges, 'Digital Soul: Intelligent Machines and Human Values,' explains how our machines can develop neurosis and what kind of therapy exist. Check this column for a summary or read this highly recommended article from Darwin Magazine for more details." -

Life Made to Order
Roland Piquepaille writes "When he was president of Celera Genomics, Craig Venter was the leader of the private project which deciphered the human genome. Now, he has another goal: create custom-made organisms -- one DNA letter at a time. 'Venter's objective is not merely to tweak existing life forms by inserting genes that confer specific traits -- the main tactic in conventional genetic engineering. Instead he wants to assemble an entire genome, DNA letter by DNA letter, putting together only the genes he wants: those necessary for an organism's survival and those that will allow it to carry out a desired task.' If successful, maybe in a decade, this could yield new sources of energy or novel drugs. Venter is not alone in this quest. Other institutions, private companies or universities, have similar efforts under development. Check this column for a summary of this eye-opening -- but quite long -- Technology Review article." -

More on Lenses with a Negative Index of Refraction
Roland Piquepaille writes "A University of Toronto researcher has developed a flat lens that doesn't respect the "normal" laws of nature and could significantly enhance the resolution of imaged objects. "The creation of an unusual flat lens may finally resolve a long-running controversy about the existence of materials that have metaphysical qualities -- so-called "metamaterials" -- that transcend the laws of nature. The lens could lead to amplified antennas, smaller cell phones and increased data storage on CD-ROMs. As says George Eleftheriades, the Toronto professor, "This is new physics." Check this column for more details and other references to metamaterials." -

Contact Lenses Could Deliver Medications
Roland Piquepaille writes "This UPI Science News article says that eye diseases like glaucoma could one day be treated by pharmaceuticals delivered through contact lenses. "Patients might be able to one day receive prescription medications through tiny particles embedded in soft contact lenses, researchers said Sunday. They said they have developed a method to encapsulate a medication in nanoparticles, particles so tiny they are microscopic and cannot be felt or seen by the eye." However, the lenses are in the very early engineering design stages and have not been tested clinically. Check this column for more details." -

Slashback: Texasocial, Networking, Attacks
Slashback this evening brings updates on social networks, Audioscrobbler, the Social Security-number security breach at the University of Texas at Austin, and more. Read on for the details.Why meet people in real life? Roland Piquepaille writes "I wrote [Saturday] a column about social-network mapping tools mentioned by Slashdot. Slashdot readers sent me many comments and e-mails about other visualization tools. Here are these new tools, in no particular order: email constellations, Apache Agora, NetVis Module, EtherApe, inGridX, NameBase's Proximity Search, Surf3D Pro and the dazzling KartOO. Finally, a reader talked about another kind of tools, the Visual Thesaurus. This web tool is not about social mapping, but it shows graphical connections between words. In this previous column, "The Visual Thesaurus: What Does it Show About Thanksgiving?," I already explored this very funny tool. Check this new story for more the details about all these tools."
Update: 03/19 00:34 GMT by T : Directly related: Josh Tyler writes "Related to a recent Slashdot posting on social networks is this paper on automatically discovering communities based on email data, just published by our group at HP Labs. We find that simple communication data is enough to identify communities, both formal and informal, and possibly even to identify the leaders of these groups."
Speaking of online community ... TGK writes "Audioscrobbler (which many of us visited the first time it was posted here) has a new site up, and most importantly, new plugins for XMMS and Winamp 3."
From the site, a capsule description of what Audioscrobbler does: "It grows to know what music you like by monitoring what songs you play on your computer. From this information you can discover other users that share some or all of your taste in music."
Feedback is always cool. An anonymous reader writes: "Sudhakar Govindavajhala, co-author of the paper referenced by the Saturday Slashdot article 'Using Memory Errors to Attack a Virtual Machine,' has responded to many of your [Slashdot readers'] questions and comments. His commentary is located at his Princeton CS website."
Another reason that Social Security isn't. GregAllen writes "Remember the recent case of SSN data theft at The University of Texas? A student has turned himself in. In his confession he says that he acted alone, and had no intention to disseminate the information. Maybe this will convince them to stop using SSNs for student IDs." Bonker also points out that "Salon is carrying an AP article that's a followup to the story a few days ago about the mass of Social Security Numbers stolen from University of Texas. Christopher Andrew Phillips is described as a 'fine young man who has never before been in trouble with the law'. Apparently he wrote a program 'to access a university Web site that tracks employees who attend training classes'. Whether or not this was done for illegitimate purposes remains to be seen. As a former UTA student, I'm glad my SSN is no longer in danger!"
What's the state of the device? An anonymous reader writes "N-Philes.com did another State of the GBA Industry Article and Roundtable. Here is the Industry Article, and here is the Roundtable"
Update: 03/19 00:34 GMT by T : And one more presroi writes "Just one week after even slashdot has noticed the new 2.2.24 linux kernel, Alan Cox has announced a new version due to a security issue found in 2.2 as well as in the 2.4 branch. I hope that we all were to lazy to upgrade from 2.2.X to .24 until now :)"

Slashback: Texasocial, Networking, Attacks
Slashback this evening brings updates on social networks, Audioscrobbler, the Social Security-number security breach at the University of Texas at Austin, and more. Read on for the details.Why meet people in real life? Roland Piquepaille writes "I wrote [Saturday] a column about social-network mapping tools mentioned by Slashdot. Slashdot readers sent me many comments and e-mails about other visualization tools. Here are these new tools, in no particular order: email constellations, Apache Agora, NetVis Module, EtherApe, inGridX, NameBase's Proximity Search, Surf3D Pro and the dazzling KartOO. Finally, a reader talked about another kind of tools, the Visual Thesaurus. This web tool is not about social mapping, but it shows graphical connections between words. In this previous column, "The Visual Thesaurus: What Does it Show About Thanksgiving?," I already explored this very funny tool. Check this new story for more the details about all these tools."
Update: 03/19 00:34 GMT by T : Directly related: Josh Tyler writes "Related to a recent Slashdot posting on social networks is this paper on automatically discovering communities based on email data, just published by our group at HP Labs. We find that simple communication data is enough to identify communities, both formal and informal, and possibly even to identify the leaders of these groups."
Speaking of online community ... TGK writes "Audioscrobbler (which many of us visited the first time it was posted here) has a new site up, and most importantly, new plugins for XMMS and Winamp 3."

New Social-Network Mapping Tools Compared
Roland Piquepaille writes "There are many new visualization tools around us which try to map our social networks. In this column, I examined Inflow, a datamining tool digging through your email repository to discover and find trends to know more about your networks. Here is a quote: "Assuming you have a significant amount of e-mail traffic, the software will create a remarkably sophisticated assessment of your various social groups, showing you not only their relative size but also the interactions between different groups." I also peeked at TouchGraph GoogleBrowser, which uses Amazon or Google Application Programming Interfaces (APIs) to visually describe how books and Web sites connect with one another. Finally, I took a look at a brand new way of visualizing Google search results, from anacubis. If you know about other similar new tools, please tell me and I'll gather your comments in a future story." -

Shelter: A Quest for Non-Toxic Housing
Crocuta writes "Many of the geeks on /. voluntarily confine themselves to their homes for vast stretches of time, but what happens when your home becomes your prison? Eric Hunting suffers from Environmental Illness which perpetually confines him to his home, which even as carefully furnished as it is, is still slowly killing him. His website, Shelter, is both a plea for help and a guide documenting one man's quest for non-toxic housing." -
Is The Earth's Rotation Changing?
Roland Piquepaille writes "We all know about the current controversies associated with the ozone layer or the global warming phenomenon. Now, the NASA's Earth Science Enterprise (ESE) is warning us that atmospheric changes or El Niño events can affect the Earth's rotation. During El Niño years, for example, the rotation of the Earth may slow ever so slightly because of stronger winds, increasing the length of a day by a fraction of a millisecond. David A. Salstein, an atmospheric scientist from Atmospheric and Environmental Research, Inc., led a recent study about this possible effect. Salstein looked at meteorological and astronomical measurements from different sources and found they were in good agreement. Check this column for a synthesis. For technical explanations, images and animations, please read this NASA paper, Changes in the Earth's rotation are in the wind." -

Tomorrow's 5G Cell Phone
Roland Piquepaille writes "According to Mitre computer scientist Joseph Mitola, next-generation cell phones might be cognitive radios (CRs), or software radios learning from interaction with their users and acting in their best interest. InfoWorld talked with him about how his vision of "cognitive radio" would work, and how it could redefine cell phone technology. Mitola said his vision is still about five to 10 years from realization, but that it could mean a sea change as control is shifted from network operators to users. He also said that sending a 10 MB email in a zone where carrier charges are high might cause the CR to alert its user, and suggest waiting until getting to the office to use the LAN instead. Finally, he talked about serious issues like privacy and security. For example, he envisions that video recognition would allow CR cell phones to visually authenticate their owners. Check this column for selected Q&As or read the full InfoWorld's interview." -
