Scammers target digital camera buyers
In preparation for my trip to
All of these vendors are listed through a web portal, http://www.lowpricedigital.com/ prominently advertised as a sponsored link at the top of the Google results page. This afternoon, I see that both The Digital Nerds and Wisetronics have upped their price for the Panasonic to $299 (A price available from Amazon and just about everybody else.) Now the third dealer on the list, http://www.digitalsuperdeals.com/, is offering the camera for $229 (and the auxiliary high-capacity battery is offered for $149.99! This web portal and all of its so-called merchant links appears to be a huge scam operation attempting to lure people in with low camera prices so they can fleece them for exorbitantly priced accessories.

Neutron diffraction offers non-destructive artifact analysis
I was doing some research on an image of a "killed" Greek helmet that I photographed at the Walters Art Museum several years ago and came across this article about a relatively new non-destructive technique for analyzing artifacts to see if they are a true antiquity or have been "tampered with".
"Neutron diffraction, an established diagnostic tool for materials analysis and non-destructive testing of engineering components, can also be used to characterise archaeological artefacts and museum objects. The phase and microstructural information obtained – without damaging an object of value – can help answer questions of authenticity, as recent investigations of 16th-century silver/copper coins and an obviously repaired 7th-century BC Greek bronze helmet show.
Neutron diffraction is a rather new diagnostic tool for studying archaeological materials. Neutrons easily penetrate through thick coatings or corrosion layers and provide information from the bulk rather than from surface areas; sampling techniques such as coring or even powdering for analysis some portion of a museum object can therefore be avoided. The large neutron beams generally used illuminate a considerable volume portion of the object and, as a result, average and representative structural information is obtained – the problems associated with the si0ngle-spot analysis of many conventional archaeometric techniques are therefore avoided. Neutron diffraction provides information on the mineral and metal phase compositions or corrosion products in objects, on the crystal structures of the constituent phases and on the microstructures. In the material sciences it is widely used for volume
texture analysis, i.e. determination of the orientations of the crystallites in polycrystalline material. Many
processes such as primary crystallisation or plastic deformations impose a characteristic texture on the
material which means that, for example, details of the production method may be imprinted in the
microstructure. Mapping grain orientation distributions – a technique called texture analysis –
reveals the creation and deformation history of an object. The crystallite distribution can be displayed
via ‘pole figures’, 2D projections of the spatial orientation distribution function that are obtained by
recording diffraction patterns for a multitude of sample orientations. The structure and texture
information can therefore provide clues on the type of material and the manufacturing techniques used
by the ancient craftsmen. " - Genuine or fake? Neutron diffraction for non-destructive testing of museum objects , Isis 2003 Science Highlights.
As for the helmet they analyzed, they discovered the nose piece had been replaced and, like the helmet I photographed at the Walters, had been ritually "killed".
"It was the custom for victorious Greek cities to dedicate tropaia, ‘trophies’ of armour from the defeated, in the sanctuary of one of the gods. When the trophy collapsed from age or when the sanctuary became too full the armour was buried, but first it was ‘killed’ as part of the process of offering it to the gods: the cheekpieces were bent
back and the noseguard turned up to render the helmet useless in this world. The finder of the helmet – probably in the 19th century and in order to sell it – straightened out the cheekpieces, which cracked at the edges and left a clear fold-line running across each of them. It is also clear that the noseguard had come off altogether, probably during
similar cosmetic straightening by the finder, for there is a clear overlapping join at the bridge of the nose."
I wonder if the Romans had any special rituals for disposing of war trophies?

Content "wraps" to replace blanket advertising
"ABC and the four other big broadcast networks are working on methods to hold the attention of TV viewers throughout the commercial breaks that interrupt the shows they want to see.
That is becoming increasingly important for two reasons. One is that more viewers are watching shows delayed rather than live, using TiVo and other DVRs. Research indicates those viewers are more likely to fast-forward through spots than those who watch live TV.
The other reason the networks need viewers to keep watching ads is that Nielsen Media Research, the ratings arbiter, intends soon to begin measuring viewership of commercials as well as programs.
One way that many networks hope to engage viewers during commercial breaks is by wedging original content into the blocks of advertising time, so that viewers will anticipate seeing something fun if they sit through a few ads.
Fox Broadcasting, for instance, tried out a series of clips for two weeks last month about an animated character named Oleg, a New York cab driver, who popped up in eight-second vignettes during commercial breaks in series like “24.” CW has been running “content wraps,” which mix sponsor products into program snippets.
Some experiments involve the cast of the shows in which the commercials appear, serving as hosts for the breaks. That is a throwback to an era when “cast commercials” proliferated with the stars of series like “I Love Lucy,” “The Beverly Hillbillies” and even “The Flintstones.”

Adjusting color with human language commands
Kevin Rivoli for the Xerox Corporation
"Adjusting color on printers should be simpler," Geoffrey Woolfe says.
To the human eye, that flower in the photo is reddish orange, that sky is light blue, that sun shines brilliant yellow.
But when software tells a printer to reproduce that image, it uses a long, unwieldy set of numbers and letters to describe those colors — and a totally different set of characters to describe shades that are a tad lighter, or a bit darker, or a whole lot brighter. The upshot is that most laymen would have to attend the computer equivalent of Berlitz to learn how to get the shades they want.
But if Xerox has its way, that will not be true much longer. This week the company introduced the software equivalent of a translator that can turn plain color speech into fluent computerese. Type the command, “Make the sun a brighter yellow,” and the printer will read, “Go with color CIELAB[88, -3, 64].”
“You shouldn’t have to be a color expert to make the sky a deeper blue or add a bit of yellow to a sunset,” said Geoffrey Woolfe, a principal scientist in the Xerox Innovation Group, who is based in Webster, N.Y., near Rochester. “So we’re providing that middle layer that turns plain speech into mathematical code.”
Color experts are already impressed. “They’ve taken common words and modifiers and transformed them into mathematical directions,” said Roy S. Berns, a professor of color science at the Rochester Institute of Technology, which has just inaugurated a doctoral program in color science.
There are still problems to be ironed out, of course. For now, the software does not differentiate between colors in different parts of an image — in other words, it can tell the printer to make all the blues darker, but it cannot yet tell it to darken the sky but lighten the ocean and leave the blue dress alone. And it is still working on a lexicon of languages — after all, a “brighter” color to one person is a “crisper” color to another and a “sharper” color to a third.
“To understand what someone means when he says the pinks need to be brighter, the software must know what pink means and what brighter means.” Professor Berns said. “And there are individual, cultural and regional differences in the way people use those words.”
Mr. Woolfe readily acknowledges the problems, and he concedes that the product is a couple of years away from commercialization. He envisions the final version as having the capability to learn. Say particular users keep typing, “no, darker” when they ask for chartreuse. “The machine will respond with a color chart that shows what it views as chartreuse, and then will let the user show what he means by the word,” Mr. Woolfe said. If it turns out the user thinks chartreuse is forest green, the software will act accordingly from then on..."Related

Trying to edit Wikipedia a frustrating process
However, when I attempted to include them in some of the biographical articles, I quickly discovered an apparent bias against the inclusion of contemporary art that is not widely known. This resulted in removal of the images within hours of inclusion. A guideline was posted to my talk page pointing out that external links to .com sources are not permitted (I had linked the artist's name to his website). I was not aware of this restriction so I removed the link and added the image back to the article. Then, I was told by another editor that he thought the images did not add anything to the article since the article already had pictures of contemporary portraits. I was aware of the contemporary portraits but many of them were highly stylized and did not provide a life-like representation like the figural images did. I added information about the year and age the portrait figure represented, consistent with the captions provided under the other portraits but again the other editor blew my edits away. I questioned his apparent censorship expressed by his rationale that the art was not widely known so had no basis for inclusion and told him I thought the internet was a place anyone could exercise their creativity without obtaining elitist-recognized status before their work could be placed before the public. But, apparently not, at least not on Wikipedia. I requested a third-party opinion and hoped my viewpoint would be shared by other editors. However, some responses to my request referred to the figures as "dolls" as did the editor I was having problems with. Despite the other reasons that were offered, I think the bias against what are perceived as "dolls" as an art form (Mr. Stuart would shudder at the description of his art form as "dolls") is the real nub of the issue. Art is ultimately in the eye of the beholder but apparently some of these editors don't wish to offer anyone else the chance to make that personal decision.
After reading a number of other contentious posts between editors arguing over points of view, relevance, etc. I realized that although Wikipedia sounds inviting (anyone can edit!) the reality is it is an environment frought with self-appointed experts who fiercely defend their fiefdoms and, in some cases, their extremely inflexible mindsets.
New standalone DVD recorders offer ease of use to the video conversion process
"we insist upon upgrading our recording technologies every few years, each time orphaning millions of disks, reels and cassettes in older formats. All over the world, VHS and camcorder tapes from the 1980s and ’90s are slowly turning to dust. And it’s becoming harder and harder to find the equipment you need to play back some of those videos.
Even the DVD will one day turn out to have been a temporary format, but at least it has advantages over tapes. The video quality is terrific. You can skip around without rewinding or fast-forwarding. And homemade DVDs may last 100 years, if you believe the vendors of those gold-coated blanks.
Now, the technologically savvy computer nut thinks nothing of connecting an old camcorder or VCR to a well-equipped Mac or PC; hitting Play; waiting two hours for each tape to transfer in real time; editing and touching up the result on the computer screen; and then waiting another two hours for the resulting video burn onto a DVD.
But in Sony’s opinion (and many other people’s), this is much too laborious, expensive and time-consuming. Enter the Sony DVDirect VRD-MC3, a $218 box that converts old (and new) videotapes into shiny new DVDs with an emphasis on two extremely important attributes: simplicity and reproduction quality.
Under the hood of the cleanly designed, black-and-white plastic case (12.7 by 4.9 by 10.6 inches) is a DVD burner that accepts almost any format of blank disc: DVD-R, DVD+R, DVD-RW, DVD+RW, and dual-layer (extra-capacity) versions of each. (There is one exception: the DVDirect doesn’t accept the dual-layer DVD-RW variety.)"
I have had a similarly positive experience with a Go Video DVD recorder that I bought on sale for only $69. I had been in the market for a DVD recorder since my Dish Network DVR started reaching its capacity and, try as I might, I couldn't find anything on it I didn't want to keep!
Just before Christmas, I saw an ad from a local discount store offering a GoVideo DVD recorder for $89 with $20 rebate (and I am meticulous about sending in my rebate coupons!) I was a little dubious about quality but I remembered we had a GoVideo VCR/DVD recorder combo unit in our technology lab at work that seemed to work well so I thought I would give it a try. After all, $69 is not much to risk if I wasn't satisfied with the results.
But, I have been pleasantly surprised with the quality of the recording (selectable from HQ (1 hr per DVD) to 2 hr, 4 hr, and 6 hr/DVD recording settings) and the editing features that enable me to rename the titles, schedule a selectable range of chapter marking intervals, select the index image for the title segment, and finalize the disk - all from the remote control. It, too has both S-Video connections as well as RCA ( the standard yellow, white and red connectors). Only the purely automatic scanning feature to establish channel reception tripped me up. Unlike many other video devices I have owned in the past, the GoVideo DVD recorder did not have a switch for Channel 3 or Channel 4 reception. You had to select the AutoScan function from the audio/video menu option under the Setup menu for the device to detect a video signal coming in on channel 3 from my Dish DVR and lock onto it.
I wish the Dish DVR would let me connect a DVD recorder to the USB outlet and (to use David Pogue's expression) slurp content from the DVR directly without having to go back through the playback process but the DISH USB has been programmed to accept only the proprietary (and quite spendy) "Pocket Dish" device.
I found a website that discusses how to disassemble the DVR and connect it to a computer to download the data from it but it is a violation of Dish's equipment lease agreement and besides, I'm more of a software kind of gal than a hardware technician. Although I have actually installed hard drives, sound systems, extra memory, internal network cards, CD-Rom drives, etc. my hands always tremble because I find it very nerve wracking.

Adobe to take Photoshop online |
Tech News on ZDNet: "Hoping to get a jump on Google and other competitors, Adobe Systems plans to release a hosted version of its popular Photoshop image-editing application within six months, the company's chief executive said Tuesday.
The online service is part of a larger move to introduce ad-supported online services to complement its existing products and broaden the company reach into the consumer market, Adobe CEO Bruce Chizen told CNET News.com.
Chizen said Adobe laid the foundation for a hosted Photoshop product with Adobe Remix, a Web-based video-editing tool it offers through the PhotoBucket media-sharing site.
Like Adobe Remix, the hosted Photoshop service is set to be free and marketed as an entry-level version of Adobe's more sophisticated image-editing tools, including Photoshop and Photoshop Elements. Chizen envisions revenue from the Photoshop service coming from online advertising.
'That is new (for Adobe). It's something we are sensitive to because we are watching folks like Google do it in different categories, and we want to make sure that we are there before they are, in areas of our franchises,' Chizen said.
Chizen described the introduction of Adobe Remix and the forthcoming hosted Photoshop as part of a larger move toward integrating hosted services into the company's product mix."

Windows VISTA features defnitely worth waiting for
Some of the things I found most helpful about the new OS:
Search and Rescue - Users of workstations with ever increasing data storage capacities have begun to flounder in their local sea of data as much as they do in the oceans of data on the internet. So, Microsoft has taken one of the best developments of the Web 2.0 revolultion, folksonomy, and incorporated it into VISTA. A user now has the ability to tag documents to facilitate location and retrieval of data.
Along with this immensely useful feature, Microsoft incorporated a powerful search function that allows users to not only search file names, tags, and types but looks within document contents. It even offers a natural language search capability, although this feature is not enabled by default. You can tell a VISTA workstation to "find emails from Robin yesterday" and it will automatically understand the application, sender and date parameters of the search.
David demonstrated how much more quickly you can click the equivalent of the Start button (it's not called start anymore) and type "calc" into the search field to launch the calculator than to select Start -> All Programs -> Accessories -> Calculator. I found myself using this feature almost intuitively as soon as he demonstrated it.
ALLOW or DENY - Despite the impression given by the currently running ad from Apple, the Security system built into VISTA was not as intrusive as I feared. When I turned on the laptop and initiated a connection to the hotel wireless system I was cautioned that the system was not secured (someting XP already did) then asked if the system was public or private. This new addition is actually quite welcome. If you select public, like you should when using any publicly provided hotspot, VISTA prevents your network activity from being seen by other users of the public service. David pointed out that you no longer have to worry about fellow coffee drinkers at Starbucks scanning your data or harvesting your passwords while you work away oblivious to their clandestine activities. You can also save the public setting for hotspot connections that you use regularly.
Windows VISTA also provides a built-in phishing filter. If you click on a link in an email message that is bogus, VISTA checks a database of known phishing sites and does not launch the linked webpage if it determines the site to be among the offenders.
VISTA also has parental controls that may seem Big Brotherish but will be welcomed by millions of concerned parents. The administrator account can enter a list of either forbidden websites or a list of approved websites by user of the system so as children grow, their parental filter can be adjusted accordingly. To accompany this feature VISTA provides a detailed logging system that can be activated to track the user activity. A parent can see not only which sites were visited but which sites the child attempted to access that were blocked (and perhaps have a meaningful discussion about them). VISTA even offers the parent the ability to monitor game usage. Not only can a parent specify that only games of a certain ESRB rating level can be played but individual game content can be filtered such as graphic violence, nudity, etc. The parent can even dictate that files cannot be downloaded (this may be a good security practice for the very young but would be too extremely limiting for adolescents).
Grouping and Stacking - David demonstrated another really useful feature called grouping and stacking. You can now group data by parameter into temporary folders with a few simple clicks. For example, if you have tagged a number of documents with a particular project name or keyword, you can instantly group them into a folder to use for batching operations. Music buffs could group music by genre or artist and instantly create temporary playlists.
Enhanced graphic tools - I was particularly excited by a new feature in graphics management. Whenever you edit an image in VISTA, it automatically creates a shadow document of the original image. Unlike Photoshop's revert to last saved feature, VISTA retains a copy of the original unedited document that can be retrieved at any time. I had been performing this type of file management for some time by always creating two copies of any downloaded images, placing one set in a folder marked original. VISTA now does it transparently. Very nice!
Well, it's time to get dressed for breakfast and prepare myself for another of David's workshops today on digital photography. I'll continue this discourse later this evening.

Web-based database system opens up Baltic museum collections
More and more museums are providing online access to their collections, making it possible to visit great cultural and historic treasures from the comfort of your home or office. The key to simple use is well-structured information, data access and site architecture. The EUREKA E! 2918 ONLINE CATALOGUE project has developed a cost-effective and easily configurable database system, simplifying access to almost any type of museum collection.
This web-based approach was developed to widen and deepen cooperation between museums in the Baltic States by improving functionality and ease-of-use, enhancing research, education and training. The system is already providing Internet access to museum collections in Latvia, Lithuania and Estonia for European and world citizens. The resulting open-architecture system will be marketed worldwide.

Robotics comes to the home front
Well, this holiday season I took a leap into robotics to actually save me time and perspiration with one of the more boring domestic chores, vacuuming. My husband and I were wandering around Sears and I lingered a while in the vacuum section since the old Kirby my husband found for me years ago weighs a bunch and as I grow older I find it more and more of a struggle to pack the old beast upstairs or from one room to another. As I walked past all the latest models I started daydreaming about the robotic vacuums I had heard about but thought to myself I would not find one of those in Sears. Lo and behold I turned a corner and there stacked up against a pillar was a shipment of Roombas - a robotic vacuum from iRobot. I was astounded to actually see one and the sales representative happily took out the rather battered looking demo and set it to the task of cleaning the rug. As I watched it swirling about, it's dirt detection light flashing like a miniature K-mart blue light special I resolved to give the little guy a try. So I shelled out the $299 (I took the more expensive Scheduler model that lets me program the time of its cleaning routines) and packed it home.
I followed the manual's recommendation to observe the Roomba in its first task to see if it had problems with any particular obstacle in the room or caught on rug fringe or draperies and found that it did have problems with some of my bedroom furniture with curved feet. However, t
I now have worked the Roomba into my daily routine. I have it clean the living room one day then the kitchen and dining room the next day. When I rearrange the furniture in the bedroom I will add it to the Roomba queue. On Saturday I set the Roomba to the task of vacuuming my home office.
Overall, I'm very pleased with this technological inroad into the domestic front and I doubt that my Roomba will instigate any plots against me with my home theater system or my steam cleaner. I see that iRobot now offers a "Create-a-bot" programmable model for any budding robotics wannabees. Now that's what I call an interactive educational experience:
iRobot Unveils Programmable Robot
Developers and Students Can Now Create Useful Robots Quickly and Easily
2007 INTERNATIONAL CES, LAS VEGAS, Jan. 8, 2007 – iRobot Corp. (NASDAQ: IRBT) today unveiled iRobot® Create™, an affordable, programmable robot designed for aspiring roboticists, advanced high-school and college students, and serious robot developers. Create comes pre-assembled, so developers can design new robots without having to build a mobile robot from scratch. The latest robot is available at www.irobot.com and pricing starts at $129.99.
“Innovators dream of creating useful robots, but they often get bogged down with designing a mobile platform that works,” said Helen Greiner, co-founder and chairman of iRobot. “iRobot Create fills a need in the robot industry for a standard, durable hardware platform on which to rapidly develop new, innovative mobile robots.”
Create is based on the core technology of iRobot Roomba®, the vacuuming robot that is cleaning millions of homes worldwide, and is compatible with Roomba’s rechargeable batteries, remote control and other accessories.
With Create, developers can now begin designing new robot applications out of the box. This new platform provides access to robot sensors and actuators via an open interface. Create also features standard connections for electronics and threaded mounting holes that allow users to secure their inventions to the robot, streamlining the integration of third-party electronics such as sensors, cameras, arms and wireless connections.
A variety of methods and programming languages can be used to control Create. Beginners can observe the robot’s behavior in one of ten demonstration modes, or they can program the robot directly by downloading short scripts with any basic terminal program. More advanced users can write programs for completely autonomous robot behavior in C or C++ using the iRobot Command Module. Developers can also create custom software and interact with Create using a variety of methods including Microsoft Robotics Studio, a Windows-based development toolkit.

ReplayTV Returns (and It’s Not Just a Rerun) - New York Times
This definitely has potential! At present I cannot transfer my Dish satellite DVR recordings to my iPod because they equipped it with a proprietary USB connection that will only talk to their own pocket Dish. I also have no way to increase the capacity of the DISH DVR either. At $100 for the software and only $20 per year subscription thereafter, their price point is right too.
ReplayTV Returns (and It’s Not Just a Rerun) - New York Times: "The new incarnation of Replay requires a computer with Windows XP, a Pentium 4 chip that is 1.3 gigahertz or faster, and a fast graphics card with 128 megabytes of video RAM. You also need a video tuner card, which lets the computer receive TV signals from cable, satellite or over the air. (The Replay software is included with some Hauppauge tuner cards.)
As with the old Replay, the new version shows two weeks of TV listings as a grid, or you can search by title, director, actor, genre or special categories like “season premieres.” All navigation can be done by keyboard or with a remote control (not included).
For $100, you get the software and the first year’s subscription; the annual fee is $20 thereafter. The company plans to offer a free 30-day trial through www.replaytv.com starting today. "

For France, Video Games Are as Artful as Cinema - New York Times
New York Times: "France is proud of its contribution to culture in such forms as existentialism, Impressionism and auteur films. Now the French culture minister wants to add Donkey Kong to his country’s pantheon of high art.
“Call me the minister of video games if you want — I am proud of this,” the minister, Renaud Donnedieu de Vabres, said in an interview last month. “People have looked down on video games for far too long, overlooking their great creativity and cultural value.”
Mr. Donnedieu de Vabres is seeking to have video games recognized as a cultural industry eligible for tax breaks, similar to French cinema.
In March, he pinned medals from the Ordre des Arts et des Lettres — a prize awarded to acknowledge cultural accomplishments — on three prominent video game designers, including Shigeru Miyamoto, the Japanese creator of Donkey Kong. The game, popularized in the 1980s, stars an Italian plumber called Mario.
Video game creators should receive a tax break of 20 percent, up to a ceiling of 500,000 euros, Mr. Donnedieu de Vabres says.
“Video games are not a mere commercial product,” he insisted. “They are a form of artistic expression involving creation from script writers, designers and directors.”"

Mississippi State Develops Effective Campus-wide Podcasting System on a Shoestring
I went to an excellent presentation this afternoon given by the IT group at Mississippi State about their lowcost, automated podcasting system using existing polycom output routed through a relatively inexpensive device (about $350 per lectern) called a Barix instreamer that converts all audio produced during a class presentation to an MP3 format. The MS group wrote a web-based front end for faculty login and input of metadata as well as an automated RSS output that automatically publishes the file to the web through links into their CMS system (they use WebCT but it would probably adapt just as well to Blackboard. The MS folks sounded like they would be willing to share their software if we were interested in developing the service here. I couldn't hardly believe that they built the entire system and rolled it out campus-wide in less than three weeks!

A Chip That Can Transfer Data Using Laser Light
New York Times: "Researchers plan to announce on Monday that they have created a silicon-based chip that can produce laser beams. The advance will make it possible to use laser light rather than wires to send data between chips, removing the most significant bottleneck in computer design.
As a result, chip makers may be able to put the high-speed data communications industry on the same curve of increased processing speed and diminishing costs — the phenomenon known as Moore’s law — that has driven the computer industry for the last four decades.
The development is a result of research at Intel, the world’s largest chip maker, and the University of California, Santa Barbara. Commercializing the new technology may not happen before the end of the decade, but the prospect of being able to place hundreds or thousands of data-carrying light beams on standard industry chips is certain to shake up both the communications and computer industries.
Lasers are already used to transmit high volumes of computer data over longer distances — for example, between offices, cities and across oceans — using fiber optic cables. But in computer chips, data moves at great speed over the wires inside, then slows to a snail’s pace when it is sent chip-to-chip inside a computer.
With the barrier removed, computer designers will be able to rethink computers, packing chips more densely both in home systems and in giant data centers. Moreover, the laser-silicon chips — composed of a spider’s web of laser light in addition to metal wires — portend a vastly more powerful and less expensive national computing infrastructure. For a few dollars apiece, such chips could transmit data at 100 times the speed of laser-based communications equipment, called optical transceivers, that typically cost several thousand dollars."

Where oh where has the RSS Link gone on Google?
I am working on a php driven website that displays information about historical figures contained in a Filemaker Pro database. One of the features desired on this website is a list of links to other resources on the web about the figure that is selected. I created a table to contain the links with various fields to relate the links to the figures individually and by group but as the compilation of links would be quite time consuming, I decided that it would be better to embed an RSS feed generated by one of the search engines based on a specifically defined search criteria instead. This would automatically update itself as new resources appear on the web.
I had used a Google-search generated RSS feed in the past so when I went up on Google and performed a search and looked for the RSS feed link I was baffled when I couldn’t find it anymore. Thinking it was just late in the day and I was just somehow overlooking the link, I called JQ and we both hunted all over for it. JQ finally found an article indicating that the feature was removed some time ago. Apparently, Google (and Yahoo) both decided that they didn’t want you to be able to easily create this time saving feature – I’m assuming it’s because RSS feeds do not contain advertising. So, JQ and I set about searching for a work around.
JQ found a blogpost about a tool developed by Ben Hammersley called Google to RSS. I found a tool developed by ResearchBuzz that will create a feed from several different search engines including special science and math search engines called Kebberfegg. Kebberfegg is a tool to help you generate large sets of keyword-based RSS feeds at one time..
With one search you can generate an RSS feed for:

I decided to use the tool from ResearchBuzz then take the feed it generates and paste it into RSS to Javascript's tool:
http://www.rss-to-javascript.com/p/138.html
and paste the resulting snippet of code in a text field in my database. Then I assigned a Php variable to that text field and call it within my PhP page. Too bad I can't rely on people to have the newest browsers that can display RSS feeds directly but I think that would be too optimistic at this point.

3D Photo Tourism Project Showcased at SIGGRAPH
Several months ago I was contacted by researchers working on an immersive 3D Photo Tourism project at the Computer Science Department at the University of Washington.
"A central goal of image-based rendering is to evoke a visceral sense of presence based on a collection of photographs of a scene. The last several years have seen signicant progress towards this goal through view synthesis methods in the research community and in commercial products such as panorama tools. One of the dreams
is that these approaches will one day allow virtual tourism of the world's interesting and important sites.
During this same time, digital photography, together with the Internet, have combined to enable sharing of photographs on a truly massive scale. For example, a Google image search on Notre Dame Cathedral returns over 15,000 photos, capturing the scene from myriad viewpoints, levels of detail, lighting conditions, seasons, decades, and so forth. Unfortunately, the proliferation of shared photographs has outpaced the technology for browsing such
collections, as tools like Google (www.google.com) and Flickr (www.ickr.com) return pages and pages of thumbnails that the user must comb through.
We present a system for browsing and organizing large photo collections of popular sites which exploits the common 3D geometry of the underlying scene. Our approach is based on
computing, from the images themselves, the photographers' locations and orientations, along with a sparse 3D geometric representation of the scene, using a state-of-the-art image-based modeling system. Our system handles large collections of unorganized photographs
taken by different cameras in widely different conditions.
We show how the inferred camera and scene information enables the following capabilities:
Scene visualization. Fly around popular world sites in 3D by morphing between photos.
Object-based photo browsing. Show me more images that contain this object or part of the scene.
Where was I? Tell me where I was when I took this picture.
What am I looking at? Tell me about objects visible in this image by transferring annotations from similar images." - Photo Tourism: Exploring Photo Collections in 3D
The researchers requested permission to use some of my pictures of Trevi Fountain for a demonstration of their new system for creating an interactive environment for visual exploration of historical sites that have been photographed from many different angles at various times of the year by many different people. The demonstration was presented at Siggraph. You can view the system at:

I recommend watching the longer movie which explains the interactive features more in depth. I found it to be a fascinating learning environment and feel honored to have had some of my images selected for inclusion in such a cutting edge project. It really motivates me to continue to build my online archive for educational use.
Weighing a Switch to a Mac
New York Times: "The physical designs of Apple’s desktop and notebook computers are often innovative. The iMac, for example, is a space-saving desktop unit with an all-in-one enclosure that conceals the computer’s components behind the monitor. And the MacBook, a new notebook with a glossy screen, includes a new keyboard layout. This week, the company introduced the Mac Pro, a line of desktops replacing the Power Mac, completing its transition to Intel chips.
But while Apple’s selection covers much ground, it is less diverse than what is available from companies like Hewlett-Packard, Dell, Sony and Lenovo. For example, Apple does not offer ultraportable notebooks, a tablet design or as wide a choice in processor types and speeds. And when it comes to pricing, Apple no longer offers notebooks in the sub-$1,000 range, or desktop units in the sub-$500 range, as do other makers.
Consideration should also be given to the compatibility of any devices like printers, external hard drives and cellphones that may be connected to a computer. In some instances, only Windows may be supported."
The Switching Experience
Danielle Wang, 26, of Austin, Tex., bought her first Mac six weeks ago. She took the advice of a friend and decided to buy a MacBook to replace her Windows-based laptop, a Sony Vaio, which she said had been stolen.
Early in the transition, Ms. Wang said, it took time to get used to the Mac interface; the menus, the location of buttons and other items were different. “It was difficult,” she said. “The first three days, I was constantly thinking about returning it.”
Ms. Wang uses the MacBook mainly for applications like e-mail, Web browsing, digital music, games and instant messaging; so far, she has not encountered problems finding Mac software, and she still maintains access to Windows-based computers for other programs she prefers to use at home.
In comparing the MacBook and the Vaio, she said the graphics were clearer on the Sony.
“The Sony Vaio is more lively,” she said. But she prefers the look and design of the MacBook."
What I find primarily disturbing about this particular case study is that essentially Ms. Wang opted for a Mac for esthetic reasons not because of product functionality. It reminds me of Steve Jobs boast at Mac World several years ago when the I-Mac was introduced with its unusual shape and color combinations. He essentially said it didn't matter how powerful the machine really is but that it looks "cool". I would like to think computer users are not that shallow.
