Demonstration of an optical technique that allows us to see small changes in the index of refraction in air. A point source of light is reflected from a concave mirror and focused onto the edge of a razor blade, which is mounted in front of the camera. Light refracted near the mirror and intercepted by the blade gives the illusion of a shadow.
Seen here are the heated gases from a candle flame and a hair dryer, helium gas, and sulfur hexafluoride gas.

Ken & R-E's Internet controlled Christmas lights
Internet Controlled Christmas Lights in Fairbanks, Alaska, USA.
This project started in 2010, when Ken and Rebecca-Ellen connected their Christmas tree lights to the internet and allowed vistors from around the world to turn the lights on and off.
The lights moved outside in 2011, as it was quite annoying to have the lights blink on and off ALL THE TIME inside the house.
The 2012 season offered the ability to control the lights surrounding the windows and the roof.
Christmas 2013 brings more lights. You can control the lights along the roof, windows, columns, door, and the lights in the wreath. We also updated the page with our current outside temperature.

The 800-pound gorilla
Google goes offline for 2 minutes, affects 40% of the Internet
It looks like Google pressed a wrong button on Friday (August 16th), most likely in the TGIF celebrations, taking down every single service that the Mountain View-based giant has to offer. This obviously includes Google Search, Gmail, YouTube, and every service in between.
According to analytics firm GoSquared, worldwide Internet traffic dropped by a whopping 40% during those hectic 120 seconds, as you can see in the graph,

eDavid the robot painter excels in numerous styles
The line between art and technology isn't just being blurred, it's being erased altogether. Painting or sketching from photographs and life, for example, is a technique that is now being mastered by robots. The latest, called eDavid, combines a camera, computer vision software, and a standard welding robot arm to skillfully recreate (in a variety of styles no less) any image you feed its software. It seems that even art, a cornerstone of human ingenuity since the dawn of man, isn't safe from a robot takeover.
Though some of the sketches of eDavid (Drawing Apparatus for Vivid Image Display) look a bit like an image run through Photoshop filters, or printed on an old dot-matrix printer, the results will send shivers down the spines of traditional artists.

These delicate geometric forms are "3D printed" from sugar
These fantastically delicate sculptures, designed by Liz and Kyle von Hasseln, bring a whole new meaning to the notion of sugar work.
The pair hit upon the idea when attempting to bake a birthday cake for a friend without the use of that most essential of bakery tools: the oven. The pair decided to 3D print a cake instead, finding success with sugar. Reasoning that others would like their sweet creations, the pair started "micro-design firm" The Sugar Lab.
According to iGnant, the pair uses a mixture of water and alcohol to wet and harden a sugar substrate into the precise forms, a process similar, the pair says, to the way frosting hardens if left in the bowl.

With 3D printing, you'll be able to replicate the world's famous sculptures
In his living room in San Diego right now, Cosmo Wenman has two life-sized reproductions of the British Museum's Head of a Horse of Selene, a magnificently life-like sculpture with nostrils flared that dates to around 432 B.C. The original in Britain is made of marble, about three feet end-to-end. Wenman's copies, created with an older digital camera and a MakerBot 3D printer, are clearly reproductions as soon as you lift them up. Created out of plastic, coated in a bronze patina, they weigh about 8 pounds each.
For the last year or so, Wenman has been casing some of the world's great sculptures for at-home replication, photographing them from every angle in plain sight inside the Getty Museum in Los Angeles, the Louvre in Paris, the Tate Britain, the British Museum and a few others.

World's First 3D Printing Photo Booth to Open in Japan
3D printers – it's a word that offers glimpses into the future that seems so far, and yet is so close. The technology, which allows you to replicate 3D objects the same way you make a photo copy, has been around for a couple years now, but, for the most part, has been far too expensive and inaccessible to the public.
But now, what's being called the world's first 3D printing photo booth is set to open for a limited time at the exhibition space EYE OF GYRE in Harajuku. From November 24 to January 14, 2013, people with reservations can go and have their portraits taken. Except, instead of a photograph, you'll receive miniature replicas of yourselves.

Quantum measurements leave Schrödinger's cat alive
Schrödinger's cat, the enduring icon of quantum mechanics, has been defied. By making constant but weak measurements of a quantum system, physicists have managed to probe a delicate quantum state without destroying it – the equivalent of taking a peek at Schrodinger's metaphorical cat without killing it. The result should make it easier to handle systems such as quantum computers that exploit the exotic properties of the quantum world.

To Infinity and Beyond
Canadian teens put a (Lego) man into space for just $400
It was probably a rather small step for Lego but it was certainly one giant leap for a Lego man when he was launched into space by a couple of Canadian teens recently.
The mission was the result of the hard work and ingenuity of friends Mathew Ho and Asad Muhammad, who worked on their project during free time on weekends. It took them four months to complete and cost just $400.
The space-bound contraption the two 17-year-olds came up with comprised an $85 weather balloon, a homemade parachute, a Styrofoam box, three point-and-shoot cameras, a wide-angle video camera, and a cell phone loaded with a GPS app so they’d be able to find the thing when it (hopefully) returned to Earth.
The finishing touch came in the form of a Lego man holding the Canadian flag strapped to a gangplank attached to their creation.

Genetic music project
The Genetic Music Project is an 'open source' collection of music made by assigning note values to the nucleotides (A, C, G, T) in DNA. (What? Never heard a T note? :-)
This one's called Where are the Roses? It's by Amy Pickard and is based on the genetic marker for bitter taste perception.
I took just the first 'paragraph' of the bitter sense code and assigned a chord to each of the markers (as your friend did, I believe). I wanted to change them as little as possible, so I left A, C, and G the same, but I changed the T to F. I did change A to A minor, as that is truly one of the bitterest chords.

Know your vortex
NASA Announces Results of Epic Space-Time Experiment
May 4, 2011: Einstein was right again. There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein's theory of gravity.
Researchers confirmed these points at a press conference today at NASA headquarters where they announced the long-awaited results of Gravity Probe B (GP-B).
"The space-time around Earth appears to be distorted just as general relativity predicts," says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission.
GP-B (twist, 550px)
"This is an epic result," adds Clifford Will of Washington University in St. Louis. An expert in Einstein's theories, Will chairs an independent panel of the National Research Council set up by NASA in 1998 to monitor and review the results of Gravity Probe B. "One day," he predicts, "this will be written up in textbooks as one of the classic experiments in the history of physics."

Kinect Hacked to Control Humanoid Robot: First Steps to Avatar
Taylor Veltrop is a software engineer and robot tinkerer, and his latest impressive feat is to link up a Microsoft Kinect via some custom software and a wireless link to his Kondo KHR-1HV kit robot. Essentially Taylor's code takes the data feed from Kinect's motion and body sensing systems, and works out what position his limbs are in before beaming that data to custom software he's installed in the robot's ROS operating system.

How to drill a square hole
An interesting technique described at Wolfram.com.
One way of getting a curve of constant width is to start with a right isosceles triangle and draw arcs of circles centered at the vertices as indicated and an additional smaller-radius arc at the top. Then if the resulting curve is rotated so that it stays inside the square that surrounds it, the locus of the apex is an exact square. By placing a cutting tool at the apex (red) this device can be used to build a drill that drills perfect square holes. One would start with a circular hole in the target material and then use the rotor to remove material so that the hole is an exact square.

Ain't it the truth?
We Have Met the Enemy and He Is PowerPoint
WASHINGTON — Gen. Stanley A. McChrystal, the leader of American and NATO forces in Afghanistan, was shown a PowerPoint slide in Kabul last summer that was meant to portray the complexity of American military strategy, but looked more like a bowl of spaghetti.
"When we understand that slide, we'll have won the war," General McChrystal dryly remarked, one of his advisers recalled, as the room erupted in laughter.
The slide has since bounced around the Internet as an example of a military tool that has spun out of control. [...]
"PowerPoint makes us stupid," Gen. James N. Mattis of the Marine Corps, the Joint Forces commander, said this month at a military conference in North Carolina. (He spoke without PowerPoint.) Brig. Gen. H. R. McMaster, who banned PowerPoint presentations when he led the successful effort to secure the northern Iraqi city of Tal Afar in 2005, followed up at the same conference by likening PowerPoint to an internal threat.

Nice detective work
An interesting tale about someone who was burgled and managed to recover the goods by tracking the cell phone.
This left myself, completely unaware of this, to come downstairs to find the door ajar, my goods missing, to stand there aghast (also known as swearing) that this could happen, stealing the most important items of mine whilst I was home!
However, now unfolds a wonderful tale of why you don't steal tech from a Compsci (or if you do, don't take the phone!).
By now it's probably about 17:30, so I resign myself to the crap of cancelling my cards, calling my mobile to confirm it wasn't available and calling the police who would arrive within an hour or so. Whilst wallowing in my own feelings of "oh crap, I need to replace shit, why didn't I get around to purchasing insurance yet?", I begin to think about whether I actually did set up some remote "wipe your phone when nicked" software. After hunting down the site and remembering my "PIN" (not a bloody password, and no email correspondence of course!), we begin to get somewhere.

Branded as scholars
Carpe Diem picks up an article in the Chronicle of Higher Education:
From the Chronicle of Higher Education:
Given that he holds a named chair "for the study of capitalism" [BB&T Professor for the Study of Capitalism at George Mason University] it is perhaps not that surprising that Pete Leeson was a keen economist even as a teenager. When he was 17, he had supply-and-demand curves tattooed on his right biceps. "People think it's fun and that I'm an oddball for having it," says Mr. Leeson. "One of my favorite things about it is the chance it gives me to talk to total strangers about economics." That, he admits, might confirm his "dorkdom," but so be it.

Google claims this is a just a software problem. That's possible - but it seems pretty unlikely to me.
Is Google Censoring Islam Suggestions?
Confused about what Islam is? Join the party — it seems Google can't figure it out either. Or, at least its search suggestion program can't.
If you type, "Buddhism is" or "Christianity is," Google will quickly show you suggestions for what it thinks you might be trying to type. In the former query's case, the Google guesses "not a religion," "wrong," "not what you think." Christianity gets tougher treatment with the suggestions "bullshit" and "not a religion."
But the query "Islam is"? Not a thing comes to mind for Google to suggest. (Search results are still there, of course.)

If you went outside at exactly the same time every day and took a picture that included the Sun, how would the Sun appear to move? With great planning and effort, such a series of images can be taken. The figure-8 path the Sun follows over the course of a year is called an analemma. This coming Tuesday, the Winter Solstice day in Earth's northern hemisphere, the Sun will be at the bottom of the analemma. [...] With even greater planning and effort, the series can include a total eclipse of the Sun as one of the images. Pictured is such a total solar eclipse analemma or Tutulemma - a term coined by the photographers based on the Turkish word for eclipse. The composite image sequence was recorded from Turkey starting in 2005. The base image for the sequence is from the total phase of a solar eclipse as viewed from Side, Turkey on 2006 March 29.

Signtific Lab: CubeSat Futures
The proliferation of micro-satellites is just the start. USAF journals like High Frontier [5/1, PDF] are already talking about nano-satellites, or in civilian parlance "CubeSats." Their effects could be profound, and will be felt in many ways. San Jose's Good Morning Silicon Valley covers an Institute for the Future project called The Signtific Lab. The premise, which you're invited to discuss and build on, is:
"...in 2019, cubesats - space satellites smaller than a shoebox - have become very cheap and very popular. For $100, anyone can put a customized personal satellite into low-earth orbit. And space data transfer protocols developed by the Interstellar Internet Project provide a basic relay backbone linking low-powered cubesats with ground stations, and with each other. Space is open.... What will you do when space is as cheap and accessible as the Web is today?"
You're welcome to participate. The exercise is open until end of day on Match 12/09, and readers can sign up to play "positive imagination" [see example] or "dark imagination" [see example] cards, or supplement existing cards with an "antagonism" card (disagree), a "momentum" card (and then what?), an "adaptation" card (introduce a twist), or an "investigation" card (follow-up questions).

500 lb Potato Battery
I built a potato battery out of 500 pounds of potatoes. It powered a small sound system. With the help of the Red 76 crew I installed the battery and sound system in the back of a U-Haul truck and drove it around town inviting people to enter the truck and take a listen. [...]
Each potato generates about 0.5 volts and 0.2 milliamperes. I connected groups of potatoes together in series to increase voltage and then connected these groups together in parallel to increase amperage. The entire 500 lb battery generated around 5 volts and 4 milliamperes.
He tells us the power he got, but not the energy. I'd like to know how many watt-hours this battery produced.

Uni. Washington and Microsoft Research collaborates on (yet another) mindblowing 3D photo viewer
If you think you've seen what's possible with Photosynth, then you've seen nothing yet. The collaborative research team from the University of Washington and Microsoft Research who only two years ago in 2006 published their paper "Photo Tourism" and their technology demonstration "Photosynth" have again pushed the boundaries of what can be achieved by intuitively processing the abundance of digital images shared on the web.
This week at SIGGRAPH 2008 they're sharing with the world some even better technology they've been working on which they call "Finding Paths through the World's Photos". Don't let the name fool you, it's damn cool. If you're not much of a reading person like me, take a look at this video demonstration. (Watch it till the end)

When I first got into this business in 1981, one of the machines I worked with was a Modcomp Classic. It came new with 512 KB of RAM (twice the RAM of the previous model) and a fast 16-bit CPU that was four RCA 4-bit processors in parallel. It had a front panel somewhat similar to the one above. (I could tell you about the old discrete-component, drum memory GE computer the Modcomp replaced but I don't want to tax your patience too much.)
To start one of these machines, you entered a simple program (a dozen instructions, say) into memory using the toggle switches on the front panel. Then you started that program running.
The program you toggled in would read the bootstrap loader, stored in ROM, into memory and start that. In turn, the loader would go looking for a boot device - a tape, a hard disk or even a card reader - and load the operating system into memory. As you can guess, this was a fairly slow process. A boot from disk that went quickly probably took about 5 minutes. If you used a tape drive (or a card reader) it took even longer.
We kept the boot instruction sequence written in machine language (hexadecimal) on the backs of punch cards on the inside of the cabinet doors. Those were the days, my friend.

How to water a cat
This automatic cat waterer at Hacked Gadgets reminded me of Harold, a cat who used to live with me many years ago.
I never made one of these for Harold, but he didn't need one. The tap in our bathtub had a very slow leak and Harold used to to get water from it by hopping into the tub and holding his paw against the tap. This caused any water that was about to drip to run down his foreleg and he'd lap it up when it got to his elbow. It was the cleverest thing I've ever seen a cat do.

Solar powered theremin
The Solar Powered Theremin (Heliophone). June 2008
This is an electronics kit suitable for beginners but it DOES require some soldering. With very few parts you can build a tiny solar powered theremin enclosed in an ALTOIDS mint tin. So when the oil runs out, the ice caps melt and civilization crumbles to dust, thanks to the Heliophone, we will still have electronic music :-)
This looks like an interesting widget to build -- but I'm not sure I'd call it a theremin. Where are the aerials that change the circuit's reactance? I think those are pretty critical elements in a thermin.
Maybe it's just the video but this device appears to change its output with changes in photon flux. So I prefer his other name Heliophone.
Here's Debussey's Claire de Lune played on thermin and piano; it's a nice demonstration of the theremin's ethereal voice. (And there are quite a few other theremin clips at YouTube.)

Gartner: Windows collapsing under its own weight; Radical change needed
Posted by Larry Dignan @ 9:07 am
Microsoft’s Windows juggernaut is collapsing as it tries to support 20 years of applications and becomes more complicated by the minute. Meanwhile, Windows has outgrown hardware and customers are pondering skipping Vista to wait for Windows 7. If Windows is going to remain relevant it will need radical changes.
That sobering outlook comes courtesy of Gartner analysts Michael Silver and Neil MacDonald. Half of a full room of IT managers and executives raised their hands when asked whether Microsoft needed to radically change its approach to Windows. “Windows is too monolithic,” says Silver.

10 MJ is 2.78 kiloWatt hours; that's the energy the typical US household uses in 2 ¼ hours, on average.

This will likely only be amusing to programmers, but I think they'll find it funny. And speaking of compilers, Steve Yegge has an pretty entertaining rant on the reasons programmers should learn about them.
These are some of the error messages produced by Apple's MPW C compiler. These are all real. (If you must know I was bored one afternoon and de-compiled the String resources for the compiler.) The compiler is 324K in size so these are just an excerpt I hope. I'm not sure where I stand on the copyright issue. - Tony Cunningham
String literal too long (I let you have 512 characters, that's 3 more than ANSI said I should)

I can't go mucking with a 'void *'
we already did this function
This label is the target of a goto from outside of the block containing this label AND this block has an automatic variable with an initializer AND your window wasn't wide enough to read this whole error message

Ordinarily, I'm a little skeptical of mathematical "discoveries"; they're just so much theology until they're verified experimentally. (To Measure is to Know.)
But last year I read John Gribbins' In Search of Schrödinger's Cat (a good layman's book about quantum mechanics) and he discusses some experiments to back his claim that parallel universes must exist. So the mathematical discovery below isn't the only basis for the claim.
Parallel universes exist - study
Parallel universes really do exist, according to a mathematical discovery by Oxford scientists described by one expert as "one of the most important developments in the history of science".
The parallel universe theory, first proposed in 1950 by the US physicist Hugh Everett, helps explain mysteries of quantum mechanics that have baffled scientists for decades, it is claimed.
In Everett's "many worlds" universe, every time a new physical possibility is explored, the universe splits. Given a number of possible alternative outcomes, each one is played out - in its own universe.

Best of What's New
Popular Science has it's Best of What's New 2007 out and here are a couple of their picks.
This first one, Nanosolar's photovoltaic panels, are in limited production with a claim they'll generate energy for 99¢ per watt. They tried to auction one of their panels on eBay recently but the auction ended early because of some kazish with eBay..
The New Dawn of Solar
Imagine a solar panel without the panel. Just a coating, thin as a layer of paint, that takes light and converts it to electricity. From there, you can picture roof shingles with solar cells built inside and window coatings that seem to suck power from the air. Consider solar-powered buildings stretching not just across sunny Southern California, but through China and India and Kenya as well, because even in those countries, going solar will be cheaper than burning coal. That’s the promise of thin-film solar cells: solar power that’s ubiquitous because it’s cheap. The basic technology has been around for decades, but this year, Silicon Valley–based Nanosolar created the manufacturing technology that could make that promise a reality.
This one sounds more like pie-in-the-sky - but maybe it will be brought to market.

Folding at home
Stanford has a distributed computing project for solving protein folding problems.
What is protein folding and how is folding linked to disease?
Proteins are biology's workhorses -- its "nanomachines." Before proteins can carry out these important functions, they assemble themselves, or "fold." The process of protein folding, while critical and fundamental to virtually all of biology, in many ways remains a mystery.
Moreover, when proteins do not fold correctly (i.e. "misfold"), there can be serious consequences, including many well known diseases, such as Alzheimer's, Mad Cow (BSE), CJD, ALS, Huntington's, Parkinson's disease, and many Cancers and cancer-related syndromes.
You can help by simply running a piece of software.
Folding@home is a distributed computing project -- people from throughout the world download and run software to band together to make one of the largest supercomputers in the world. Every computer takes the project closer to our goals. Folding@home uses novel computational methods coupled to distributed computing, to simulate problems millions of times more challenging than previously achieved.

Mankind 'shortening the universe's life'
By Roger Highfield, Science Editor
Last Updated: 12:01am GMT 21/11/2007
Forget about the threat that mankind poses to the Earth: our activities may be shortening the life of the universe too.
The startling claim is made by a pair of American cosmologists investigating the consequences for the cosmos of quantum theory, the most successful theory we have. Over the past few years, cosmologists have taken this powerful theory of what happens at the level of subatomic particles and tried to extend it to understand the universe, since it began in the subatomic realm during the Big Bang.
The damaging allegations are made by Profs Lawrence Krauss of Case Western Reserve University in Cleveland, Ohio, and James Dent of Vanderbilt University, Nashville, who suggest that by making this observation in 1998 we may have caused the cosmos to revert to an earlier state when it was more likely to end. "Incredible as it seems, our detection of the dark energy may have reduced the life-expectancy of the universe," Prof Krauss tells New Scientist.

1K of ROM
MacRaven excerpts and links to a /. post about some digital archaeologists with a project to simulate and document the Busicom 141-PF calculator. That calculator was based on Intel's first microprocessor, the 4004, which was introduced 35 years ago. (Here's the Intel 4004 35th Anniversary Project site.)
This quote from the /. post
Want to find out how Busicom's Masatoshi Shima compressed an entire four-function, printing calculator into only 1,024 bytes of ROM?
caught my eye because it reminded me of an old Usenet tale about "real programmers." That tale - in all its lengthy glory - follows. If you're a codewright it will either bring back memories, or give you something to think about, or possibly do both.
A recent article devoted to the *macho* side of programming made the bald and unvarnished statement: Real Programmers write in Fortran.
Maybe they do now,in this decadent era of Lite beer, hand calculators and "user-friendly" software but back in the Good Old Days, when the term "software" sounded funny and Real Computers were made out of drums and vacuum tubes, Real Programmers wrote in machine code. Not Fortran. Not RATFOR. Not, even, assembly language.
Machine Code. Raw, unadorned, inscrutable hexadecimal numbers. Directly.
Lest a whole new generation of programmers grow up in ignorance of this glorious past, I feel duty-bound to describe, as best I can through the generation gap, how a Real Programmer wrote code. I'll call him Mel, because that was his name.
I first met Mel when I went to work for Royal McBee Computer Corp., a now-defunct subsidiary of the typewriter company. The firm manufactured the LGP-30, a small, cheap (by the standards of the day) drum-memory computer, and had just started to manufacture the RPC-4000, a much-improved, bigger, better, faster -- drum-memory computer. Cores cost too much, and weren't here to stay, anyway. (That's why you haven't heard of the company, or the computer.)
I had been hired to write a Fortran compiler for this new marvel and Mel was my guide to its wonders. Mel didn't approve of compilers.
"If a program can't rewrite its own code," he asked, "what good is it?"
Mel had written, in hexadecimal, the most popular computer program the company owned. It ran on the LGP-30 and played blackjack with potential customers at computer shows. Its effect was always dramatic. The LGP-30 booth was packed at every show, and the IBM salesmen stood around talking to each other. Whether or not this actually sold computers was a question we never discussed.
Mel's job was to re-write the blackjack program for the RPC-4000. (Port? What does that mean?) The new computer had a one-plus-one addressing scheme, in which each machine instruction, in addition to the operation code and the address of the needed operand, had a second address that indicated where, on the revolving drum, the next instruction was located. In modern parlance, every single instruction was followed by a GO TO! Put *that* in Pascal's pipe and smoke it.
Mel loved the RPC-4000 because he could optimize his code: that is, locate instructions on the drum so that just as one finished its job, the next would be just arriving at the "read head" and available for immediate execution. There was a program to do that job, an "optimizing assembler", but Mel refused to use it.
"You never know where its going to put things", he explained, "so you'd have to use separate constants".
It was a long time before I understood that remark. Since Mel knew the numerical value of every operation code, and assigned his own drum addresses, every instruction he wrote could also be considered a numerical constant. He could pick up an earlier "add" instruction, say, and multiply by it, if it had the right numeric value. His code was not easy for someone else to modify.
I compared Mel's hand-optimized programs with the same code massaged by the optimizing assembler program, and Mel's always ran faster. That was because the "top-down" method of program design hadn't been invented yet, and Mel wouldn't have used it anyway. He wrote the innermost parts of his program loops first, so they would get first choice of the optimum address locations on the drum. The optimizing assembler wasn't smart enough to do it that way.
Mel never wrote time-delay loops, either, even when the balky Flexowriter required a delay between output characters to work right. He just located instructions on the drum so each successive one was just *past* the read head when it was needed; the drum had to execute another complete revolution to find the next instruction. He coined an unforgettable term for this procedure. Although "optimum" is an absolute term, like "unique", it became common verbal practice to make it relative: "not quite optimum" or "less optimum" or "not very optimum". Mel called the maximum time-delay locations the "most pessimum".
After he finished the blackjack program and got it to run, ("Even the initializer is optimized", he said proudly) he got a Change Request from the sales department. The program used an elegant (optimized) random number generator to shuffle the "cards" and deal from the "deck", and some of the salesmen felt it was too fair, since sometimes the customers lost. They wanted Mel to modify the program so, at the setting of a sense switch on the console, they could change the odds and let the customer win.
Mel balked. He felt this was patently dishonest, which it was, and that it impinged on his personal integrity as a programmer, which it did, so he refused to do it. The Head Salesman talked to Mel, as did the Big Boss and, at the boss's urging, a few Fellow Programmers. Mel finally gave in and wrote the code, but he got the test backwards, and, when the sense switch was turned on, the program would cheat, winning every time. Mel was delighted with this, claiming his subconscious was uncontrollably ethical, and adamantly refused to fix it.
After Mel had left the company for greener pa$ture$, the Big Boss asked me to look at the code and see if I could find the test and reverse it. Somewhat reluctantly, I agreed to look. Tracking Mel's code was a real adventure.
I have often felt that programming is an art form, whose real value can only be appreciated by another versed in the same arcane art; there are lovely gems and brilliant coups hidden from human view and admiration, sometimes forever, by the very nature of the process. You can learn a lot about an individual just by reading through his code, even in hexadecimal. Mel was, I think, an unsung genius.
Perhaps my greatest shock came when I found an innocent loop that had no test in it. No test. *None*. Common sense said it had to be a closed loop, where the program would circle, forever, endlessly. Program control passed right through it, however, and safely out the other side. It took me two weeks to figure it out.
The RPC-4000 computer had a really modern facility called an index register. It allowed the programmer to write a program loop that used an indexed instruction inside; each time through, the number in the index register was added to the address of that instruction, so it would refer to the next datum in a series. He had only to increment the index register each time through. Mel never used it.
Instead, he would pull the instruction into a machine register, add one to its address, and store it back. He would then execute the modified instruction right from the register. The loop was written so this additional execution time was taken into account -- just as this instruction finished, the next one was right under the drum's read head, ready to go. But the loop had no test in it.
The vital clue came when I noticed the index register bit, the bit that lay between the address and the operation code in the instruction word, was turned on-- yet Mel never used the index register, leaving it zero all the time. When the light went on it nearly blinded me.
He had located the data he was working on near the top of memory -- the largest locations the instructions could address -- so, after the last datum was handled, incrementing the instruction address would make it overflow. The carry would add one to the operation code, changing it to the next one in the instruction set: a jump instruction. Sure enough, the next program instruction was in address location zero, and the program went happily on its way.
I haven't kept in touch with Mel, so I don't know if he ever gave in to the flood of change that has washed over programming techniques since those long-gone days. I like to think he didn't. In any event, I was impressed enough that I quit looking for the offending test, telling the Big Boss I couldn't find it. He didn't seem surprised.
When I left the company, the blackjack program would still cheat if you turned on the right sense switch, and I think that's how it should be. I didn't feel comfortable hacking up the code of a "Real Programmer".

TubeStop is a nice extension for Firefox which will defeat the auto-play feature on YouTube videos. Meaning that they don't start downloading and playing until you hit the Play button. If you often have several links to YouTube open, this can be real handy. I've tried this and like it.
YouConvertIt is a site where you can convert document, image, audio and video files after uploading them. I haven't tried this one (because an e-mail address is required) but it looks interesting.

Why we all sell code with bugs
Creating quality software products means knowing when to fix bugs and when to leave well alone, writes Eric Sink
Thursday May 25, 2006
The world's six billion people can be divided into two groups: group one, who know why every good software company ships products with known bugs; and group two, who don't. Those in group 1 tend to forget what life was like before our youthful optimism was spoiled by reality. Sometimes we encounter a person in group two, a new hire on the team or a customer, who is shocked that any software company would ship a product before every last bug is fixed.

A scratch monkey
A really old one, but worth retelling.
THE UNTIMELY DEMISE OF MABEL THE MONKEY, a cautionary tale
The following, modulo a couple of inserted commas and capitalization changes for readability, is the exact text of a famous USENET message. (NOTE: PM means "preventive maintenance" and MOUNT is used as in "mount
a tape"; that is, to load a tape onto a drive.)
Date: Wed 3 Sep 86 16:46:31-EDT
From: "Art Evans"
Subject: Always Mount a Scratch Monkey
My friend Bud used to be the intercept man at a computer vendor for calls when an irate customer called. Seems one day Bud was sitting at his desk when the phone rang.
Voice: YOU KILLED MABEL!!
B: Excuse me?
V: YOU KILLED MABEL!!
This went on for a couple of minutes and Bud was getting nowhere, so he decided to alter his approach to the customer.
B: HOW DID I KILL MABEL?
V: YOU PM'ED MY MACHINE!!
Well, to avoid making a long story even longer, I will abbreviate what had happened. The customer was a Biologist at the University of Blah-de-blah, and he had one of our computers that controlled gas mixtures that Mabel (the monkey) breathed. Now, Mabel was not your ordinary monkey. The University had spent years teaching Mabel to swim, and they were studying the effects that different gas mixtures had on her physiology. It turns out that the repair folks had just gotten a new Calibrated Power Supply (used to calibrate analog equipment), and at their first opportunity decided to calibrate the D/A converters in that computer. This changed some of the gas mixtures and poor Mabel was asphyxiated. Well, Bud then called the branch manager for the repair folks:
B: This is Bud, I heard you did a PM at the University of Blah-de-blah.
M: Yes, we really performed a complete PM. What can I do for you?
B: Can you swim?
The moral is, of course, that you should always mount a scratch monkey.

IBM Stores Data on Single Atoms
New nanotech breakthroughs have enabled IBM to measure magnetic fields at an atomic level and to build transistor-like switches from a single molecule.
Ben Ames, IDG News Service
Friday, August 31, 2007 12:00 PM PDT
IBM Corp. has demonstrated how to perform certain computer functions on single atoms and molecules, a discovery that could someday lead to processors the size of a speck of dust, the company said Thursday.
Researchers at IBM's Almaden Research Center in California developed a technique for measuring magnetic anisotropy, a property of the magnetic field that gives it the ability to maintain a particular direction. Being able to measure magnetic anisotropy at the atomic level is a crucial step toward the magnet representing the ones or the zeroes used to store data in binary computer language.

FAQ: The Monster.com mess
Job search site looting goes back weeks, maybe months
August 24, 2007 (Computerworld) -- The last thing you need when you're unemployed is a bank account that's suddenly emptied. But that's exactly what some unwary users of employment search site Monster.com faced after identity thieves made off with the personal information of more than a million people looking for jobs.
This still-developing story has enough nooks and crannies to confuse a gumshoe, but some facts are clear: Monster's resume database was looted, and the personal information taken was used to forge convincing messages that deposited password-stealing Trojans and ransomware on users' PCs.

Weekend Reading 21
This week's topic: Microsoft's Vista.
The days of On the Internet, nobody knows you're a dog appear to be fading fast...
Forget about the WGA! 20+ Windows Vista Features and Services Harvest User Data for Microsoft
By: Marius Oiaga, Technology News Editor
Are you using Windows Vista? Then you might as well know that the licensed operating system installed on your machine is harvesting a healthy volume of information for Microsoft. In this context, a program such as the Windows Genuine Advantage is the last of your concerns. In fact, in excess of 20 Windows Vista features and services are hard at work collecting and transmitting your personal data to the Redmond company.
And CodeWritinFool sends a link to A Cost Analysis of Windows Vista Content Protection by Peter Gutmann in New Zealand.
The point Mr. Gutman makes below ought to scare everyone who uses a computer, no matter what system it runs.
As a user, there is simply no escape. Whether you use Windows Vista, Windows XP, Windows 95, Linux, FreeBSD, OS X, Solaris (on x86), or almost any other OS, Windows content protection will make your hardware more expensive, less reliable, more difficult to program for, more difficult to support, more vulnerable to hostile code, and with more compatibility problems. Because Windows dominates the market and device vendors are unlikely to design and manufacture two different versions of their products, non-Windows users will be paying for Windows Vista content-protection measures in products even if they never run Windows on them.
Here's an offer to Microsoft: If we, the consumers, promise to never, ever, ever buy a single HD-DVD or Blu-Ray disc containing any precious premium content [Note M], will you in exchange withhold this poison from the computer industry? Please?

These stories about computer-driven parts fabrication remind me of the "integrating pantograph," a factory-in-a-box mentioned in Heinlein's story Gulf.

Solid freeform fabrication: DIY, on the cheap, and made of pure sugar
In February we gave a sneak preview of our project to construct a home-built three dimensional fabricator. Our design goals were (1) a low cost design leveraging recycled components (2) large printable volume emphasized over high resolution, and (3) ability to use low-cost printing media including granulated sugar. We are extremely pleased to be able to report that it has been a success: Our three dimensional fabricator is now fully operational and we have used it to print several large, low-resolution, objects out of pure sugar.
This story from the New York TImes talks about the Desktop Factory, a "printer" using a similar technique to make parts of plastic instead of sugar.

Encyclopedia of Life
I hadn't heard about this site called the Encyclopedia of Life before I read about it in the Post-Dispatch today. But the most surprising thing to me was that it appeared on the P-D's front page. A website is front page news in a dead-tree paper? Hmm... slow news day, maybe?
One reason for this prominent placement in the P-D is that the Missouri Botanical Garden (in St. Louis) is one of the six "cornerstone institutions" in the founding of this encyclopedia.

How Credit-Card Data Went Out Wireless Door
Biggest Known Theft Came from Retailer With Old, Weak Security
By JOSEPH PEREIRA
May 4, 2007; Page A1
The biggest known theft of credit-card numbers in history began two summers ago outside a Marshalls discount clothing store near St. Paul, Minn.
There, investigators now believe, hackers pointed a telescope-shaped antenna toward the store and used a laptop computer to decode data streaming through the air between hand-held price-checking devices, cash registers and the store's computers. That helped them hack into the central database of Marshalls' parent, TJX Cos. in Framingham, Mass., to repeatedly purloin information about customers.
The $17.4-billion retailer's wireless network had less security than many people have on their home networks, and for 18 months the company -- which also owns T.J. Maxx, Home Goods and A.J. Wright -- had no idea what was going on.
The company says the hackers may even have lifted bank-card information as customers making purchases waited for their transactions to be approved. TJX transmitted that data to banks "without encryption," it acknowledged in an SEC filing. That violates credit-card company guidelines, experts say.

Beer Maker, Scientists To Create Energy
By Rod Mcguirk
May 3, 2007 7:55AM
The fuel cell derived from beer waste water is essentially a battery in which bacteria consume water-soluble brewing waste such as sugar, starch and alcohol. The battery produces electricity plus clean water, said Professor Jurg Keller, the university's wastewater expert.
Scientists and Australian beer maker Foster's are teaming up to generate clean energy from brewery waste water -- by using sugar-consuming bacteria.
The experimental technology was unveiled Wednesday by scientists at Australia's University of Queensland, which was given a $115,000 state government grant to install a microbial fuel cell at a Foster's Group brewery near Brisbane, the capital of Queensland state.

What a gem
I've been waiting a couple of years for the prices of digital cameras to fall enough to make them really cheap. By that I mean cheap enough that I wouldn't mind very much if I lost one; almost disposable in other words. When I saw the first multi-megapixel cameras selling for around $50 last year, I figured the time was getting ripe. Then I ran across Billy Beck raving about the Sanyo C40 and how Radio Shack was letting them go for only $200. While that price moved it out of the "disposable" category, its video capability made it too attractive to pass up.
I was too busy that week to make it to Radio Shack so I missed out. They didn't stay in stock very long at that price. When I finally had a little time to do some searching, I found a used one ("like new, in the box") for sale by an Amazon reseller and bought it for $225. It may not be the best $200 I've ever spent, but it's certainly the best in the tech toys category. This camera is a very fine piece of work.
Here's what it looks like. After you get the view screen up, the lens cap off and you turn it on, you can operate this thing with your thumb.
With the view screen folded down, it's just a bit larger than a cigarette pack and weighs only 5.5 ounces. So it fits easily into most pockets.
It takes 4 megapixel still images. Here's a still image (pop-up) that I took at a friend's house last night.
Or it takes video at a variety of sizes and frame rates, up to 640 x 480 at 30 frames-per-second. Or it will do both at the same time. Or you can use it as webcam for your PC, if you're running Windows XP or later.
In the HQ recording mode, which is touted as "television quality", you can record up to 2 hours of video on a 2 GB card. If you use SHQ mode (the best), you can record about 85 minutes of video on the same card. The TV quality recordings are not high-def. But they look good - well, as good as TV looks - when played back on a television monitor.
This cam also featues video trimming on the camera and digital stabilization for recording. The stabilization works well: I took a few minutes of video while riding in a car (no, I wasn't driving) and I was amazed at how steady the playback looked.
Since I spent a couple of days on my agricultural project this week, here's 30 seconds of someone getting a lesson in how to drive a John Deere. I trimmed this clip on the camera and then used Sorenson's Squeeze to convert the MPEG4 into this Flash clip.
But wait... there's more. Sanyo ships this thing with a couple of utility programs: Ulead's DVD MovieFactory and a program of their own called MotionDirector. I haven't played with the Ulead software yet, but the MotionDirector program will make a panoramic JPEG or a QuickTime VR 'movie' out of a video clip.
For example, if you pan the camera over a landscape, MotionDirector can generate a panoramic image from a series of frames in the movie. Click in the QuickTime movie below to pan over the landscape.
Whether you're looking for an inexpensive tool so you can hang out your shingle as a Citizen Journalist - or you're just a hobbyist like me - you can do a lot worse than to pick up this cam. I've been very impressed with it.

Some scientists are going to test whether reverse causality -- current events that change the past -- can occur.
Retrocausality offers an alternative explanation. Measuring one entangled particle could send a wave backward through time to the moment at which the pair was created. The signal would not need to move faster than light; it could simply retrace the first particle's path through space-time, arriving back at the spot where the two particles were emitted. There, the wave can interact with the second particle without violating relativity. "Retrocausation is a nice, simple, classical explanation for all this," Dowe says.
Right. One can only admire Mr. Dowe's calling that a "nice, simple... explanation." Of course, anything cooked up by R. Feynman and J. A. Wheeler is bound to make your brain ache.

Cheap solar power poised to undercut oil and gas by half
By Ambrose Evans-Pritchard
Last Updated: 11:31pm GMT 18/02/2007
Within five years, solar power will be cheap enough to compete with carbon-generated electricity, even in Britain, Scandinavia or upper Siberia. In a decade, the cost may have fallen so dramatically that solar cells could undercut oil, gas, coal and nuclear power by up to half. Technology is leaping ahead of a stale political debate about fossil fuels.
Anil Sethi, the chief executive of the Swiss start-up company Flisom, says he looks forward to the day - not so far off - when entire cities in America and Europe generate their heating, lighting and air-conditioning needs from solar films on buildings with enough left over to feed a surplus back into the grid.
"We don't need subsidies, we just need governments to get out of the way and do no harm. They've spent $170bn subsidising nuclear power over the last thirty years," he said.

Pretty hilarious - if you're geeky.
When I was a T.A., a student came to me wondering why his Pascal program wouldn't print anything. I compiled it and ran it myself, and sure enough, no output. I looked through the program, and the WRITELNs were there. This became a problem I had to solve. I added some of my own, and still, nothing was written to the screen.
After about 15 minutes of careful examination, I noticed that the entire program had been commented out. This guy was compiling a comment.
I pointed this out to him, but he said to me, "Yeah, but I had to do that. It was the only way to get rid of all of the errors."

The secret of DNA
Here's an old one from rec.humor.funny that I've always enjoyed. "How old?" you might ask. Old enough that it will probably be new to many, I'll guess. Unfortunately, I don't know who wrote it.
For many years molecular biologists have been mystified by the fact that very little of an organism's DNA seems to serve any useful function.
I have solved the mystery.
The reason why only 30% of human DNA performs any useful function is that the rest of it is comments.
Once we decode a typical human genome, we see that the contents begin as follows:
* Human Genome
* Version 2.1

One of the most feared colors in the NT world is blue. The infamous Blue Screen of Death (BSOD) will pop up on an NT system whenever something has gone terribly wrong. Bluescreen is a screen saver that not only authentically mimics a BSOD, but will simulate startup screens seen during a system boot.

Steve F sends this somewhat long piece about WD-40 (most of which is confirmed at the company's site). Next week, maybe, we'll have one about duct tape.
The product began from a search for a rust preventative solvent and degreaser to protect missile parts. WD-40 was created in 1953 by three technicians at the San Diego Rocket Chemical Company. Its name comes from the project that was to find a "water displacement" compound. They were successful with the fortieth formulation, thus WD-40.
The Convair Company bought it in bulk to protect their Atlas missile parts. Their workers were so pleased with the product they began smuggling (also known as "shrinkage" or "stealing") it out to use at home.
The Rocket Chemical Co. executives decided there might be a consumer market for it and put it in aerosol cans. The rest is history. It is a carefully guarded recipe known only to four people. One of them is the "brew master." There are about 2.5 million gallons of the stuff manufactured each year. It gets its distinctive smell from a fragrance that is added to the brew. Ken East (one of the original founders) says there is nothing in WD-40 that would hurt you.
Here are a few of the 1000s of uses:
- Protects silver from tarnishing
- Cleans and lubricates guitar strings
- Gets oil spots off concrete driveways
- Gives floors that 'just-waxed' sheen without making it slippery
- Keeps flies off cows
- Restores and cleans chalkboards
- Removes lipstick stains
- Loosens stubborn zippers
- Untangles jewelry chains
- Removes stains from stainless steel sinks
- Removes dirt and grime from the barbecue grill
- Keeps ceramic & terra cotta garden pots from oxidizing
- Removes tomato stains from clothing
- Keeps glass shower doors free of water spots
- Camouflages scratches in ceramic and marble floors
- Keeps scissors working smoothly
- Lubricates noisy door hinges on vehicles and doors in homes
- Gives a children's play gym slide a shine for a super fast slide
- Lubricates gear shift and mower-deck lever for ease of handling on riding mowers
- Rids rocking chairs and swings of squeaky noises
- Lubricates tracks in sticking home windows and makes them easier to open
- Spraying an umbrella stem makes it easier to open and close
- Restores and cleans padded leather dashboards and vinyl bumpers
- Restores and cleans roof racks on vehicles
- Lubricates and stops squeaks in electric fans
- Lubricates wheel sprockets on tricycles, wagons and bicycles for easy handling
- Lubricates fan belts on washers and dryers and keeps them running smoothly
- Keeps rust from forming on saws and saw blades, and other tools
- Removes splattered grease on stove
- Keeps bathroom mirror from fogging
- Lubricates prosthetic limbs
- Keeps pigeons off the balcony (they hate the smell)
- Removes all traces of duct tape
- Some folks spray it on their arms, hands, and knees to relieve arthritis pain.
- The favorite use in the state of New York: WD-40 protects the Statue of Liberty from the elements.
- WD-40 attracts fish. Spray a LITTLE on live bait or lures and you will be catching the big one in no time. It's a lot cheaper than the chemical attractants that are made for just that purpose. Keep in mind though, using some chemical laced baits or lures for fishing is not allowed in some states.
- Keeps away chiggers on the kids
- Use it for fire ant bites. It takes the sting away immediately, and stops the itch.
- WD-40 is great for removing crayon from walls. Spray on the mark and wipe with a clean rag.
- Also, if you've discovered that you have washed and dried a tube of lipstick with a load of laundry, saturate the lipstick spots with WD-40 and re-wash. Presto! Lipstick is gone!
- If you sprayed WD-40 on the distributor cap, it would displace the moisture and allow the car to start. (If I knew what a distributor cap was, it might help)
- WD-40, long known for its ability to remove leftover tape smunges (sticky label tape), is also a lovely perfume and air freshener! Sprayed liberally on every hinge in the house, it leaves that distinctive clean fresh scent for up to two days!
- Seriously though, it removes black scuff marks from the kitchen floor! Use WD-40 for those nasty tar and scuff marks on flooring. It doesn't seem to harm the finish and you won't have to scrub nearly as hard to get them off. Just remember to open some windows if you have a lot of marks.
- Bug guts will eat away the finish on your car if not removed quickly! Use WD-40!

Concept 'car' (Toyota's iSwing):
September 20, 2006
F R (sorry, Steve) send these images of the largest hobbyist R/C craft I've seen. (7 images total - all pop-ups.)
This 1/9th scale radio-controlled C-17 model was built in the United Kingdom. To date it has about 20 flights. It was built as the centerpiece of a 15-program television series produced in the U.K. for the Home and Leisure satellite TV channel. Built with the aid of three friends, it took one year to build and is powered with 4 Jetcat P-120 turbines with a total thrust of 108 lbs. The models weighs over 250 lbs fuelled and carries 12.5 liters (3.3 US gallons) of 95% kerosene and 5% turbine oil fuel.
Other details include 5 Futaba PCM receivers, 16 battery packs (93 cells), 20 Futaba servos, on -board air compressor, electro/pneumatic retracts, etc. Wingspan is 20 feet 8 inches and the top of the fin is 74 inches (6 feet 2 inches) above the ground. Takeoff weight is 264 lbs.
The rear cargo doors open and they drop an r/c jeep on a pallet, as well as 2 free-fall r/c parachutists. The model also has smoke systems both of the inboard turbines, and uses 2.4 GHz data link to provide real-time data to a laptop computer on the ground while in flight; this data includes airspeed, turbine RPM, EGT, fuel consumption, etc. It is covered in fiberglass and epoxy resin. Built mainly from balsa and ply, with many glass and carbon fiber moldings to reduce weight, this C-17 Globemaster III is one of the largest jet models in the world today! Complete with retractable landing gear and pneumatically operated flaps.
The four builders are shown in the image above. Colin Straus, the owner, is at the nose of the aircraft.

The most interesting thing to me about the outrageous -- blasphemous? -- claim below is that this Steorn company took out an ad in The Economist seeking physicists to validate their technology. Nothing more than slick PR, I'd say, but I do admire their chutzpah.
We have developed a technology that produces free, clean and constant energy.
This means never having to recharge your phone, never having to refuel your car. A world with an infinite supply of clean energy for all.
Our technology has been independently validated by engineers and scientists - always off the record, always proven to work.
Here's an interesting interview with Steorn's CEO at PureEnergySystems.com, an "alternative energy" site.
Tesla road test
In my last post about the Tesla Roadster, I said they'd have to show me. While I still haven't driven one of their cars myself, Ben Stewart has and he wrote about it at the Popular Mechanics automotive blog.
So it seems Tesla has more than just a slick website (and a great name). They have at least one electric car and a fairly positive review of it.

Nate True built this fountain using water treated with a flourescent dye and some UV LEDs that provide a strobe light for the droplets. He can produce some very interesting effects with the strobing LEDs, such as making the fountain "run backward." Very impressive.
Check out the video and his description.
Even though I find it very amusing personally, I try not to link to TheDailyWTF so I won't bore too many non-technical folks. But this one is just too bizarre to pass up and you non-technical folks will just have to take your chances.
Now, fellow coders, engineers, and designers, can you say, "Code it in Visio"? Yep, that Visio - the formerly 3rd-party software that Microsoft bought back in 2000 and rolled into MS Office (sort of).
You'll need to visit TheDailyWTF to appreciate what follows.
When I first saw it, I thought it was some sort of circuit diagram. Actually, it's a Visio diagram (12 of 136) that contains one of these complex workflow modules. Let me rephrase that: the diagram doesn't represent the workflow or show how the workflow is coded, it is the workflow. Let's take a look at a closeup.

we set iptables to forward everything to a transparent squid proxy running on port 80 on the machine.

Radical new tire design by Michelin. The next generation of tires. They had a pair at the Philadelphia car show. These tires are airless and are scheduled to be out on the market very soon. The bad news for law enforcement is that spike strips will not work on these tires.
This is what great R&D will do and just think of the impact on existing technology:
These are actual pictures taken in the South Carolina plant of Michelin. It will be awhile before they are available to the automotive industry.

The BrainGate™ Neural Interface System is currently the subject of a pilot clinical trial being conducted under an Investigational Device Exemption (IDE) from the FDA. The system is designed to restore functionality for a limited, immobile group of severely motor-impaired individuals. It is expected that people using the BrainGate™ System will employ a personal computer as the gateway to a range of self-directed activities. These activities may extend beyond typical computer functions (e.g., communication) to include the control of objects in the environment such as a telephone, a television and lights.

This snippet comes from a post titled Why I Hate Frameworks at Joel Spolsky's Joel on Software site. If you're in the software dev business, it will have you in stitches.
So this week, we're introducing a general-purpose tool-building factory factory factory, so that all of your different tool factory factories can be produced by a single, unified factory. The factory factory factory will produce only the tool factory factories that you actually need, and each of those factory factories will produce a single factory based on your custom tool specifications. The final set of tools that emerge from this process will be the ideal tools for your particular project. You'll have *exactly* the hammer you need, and exactly the right tape measure for your task, all at the press of a button (though you may also have to deploy a few *configuration files* to make it all work according to your expectations).

Peer-to-peer is finally here
I've been biting my figurative tongue for over a year now, waiting for the time when I could write a post about this. The CodeWritinFool (one of our regular contributors) and his partner J.R. (another regular) are ready to release some software they've been working on.
What is it? Well, it's a peer-to-peer backup program that they call BackUpStream.
If you spend any time at all thinking about how to back up your disc drives, you'll realize that peer-to-peer backup is a really neat idea. You can arrange your back-ups to be offsite at a friend's house -- or at several friends' houses -- without any of those monthly charges you'd pay for a "network backup" service with the same (or fewer) features. And you can reciprocate by letting your friends back up their drives to your machine(s). All you need is a network connection and BackUpStream.
"Collaborative back-up" is the concept in a nutshell.
Or, if you're interested in enterprise-type use, BackUpStream lets you get off-site backups between different office sites, or between home and office, and so on.
What I particularly like about BackUpStream is that I can run it on different machines on my LAN at home and have them automatically backed-up to each other on a regular schedule. At a time when hard drives come with 1-year warranties, a good back-up is just as important as ever.
Another nice touch is the wizard-like approach to backing up application data files. Want to back up just your e-mail files and your Excel spreadsheets? BackUpStream will find those on your drives and take care of it.
Naturally, there's a whole list of other interesting features - including great security. They've put a lot of time and thought into how it works. But rather than list those features here, you can read them for yourself at BackUpStream.com.
Check out the free trial version. BackUpStream is a nice piece of work and I think it will do well.

Heath Robinson Rube Goldberg computer
Tim writes, "This has an incredibly high geek factor."
This proposed HRRB computer project is named in honor of British cartoonist and illustrator William Heath Robinson (1872-1944) and his American counterpart Reuben Lucius Goldberg (1883-1970). Robinson and Goldberg were both famous for creating illustrations of machines that were intended to perform relatively simple tasks, but whose implementations were incredibly complex such that they performed their tasks in exceedingly convoluted and indirect ways.
Just to set the scene, take a look at the photo below. This shows a relay-based computer created by Professor Harry Porter III, who is a lecturer at Portland State University. (You can find out more about this little rapscallion on Harry's Website).

Farewell, my lovely
A goodbye to Borland's Delphi at The Register:
Farewell my lovely
By Verity Stob
Published Tuesday 7th March 2006 10:14 GMT
- And it came to pass that the Sons of Kahn, who dwelt in the valley of the Scotts, fell yet again upon interesting times. And their fortune did wax and wane, only with not so much of the wax.
- And they did bring forth a version of Delphi called '2005'. But the users of Delphi looked upon it with scorn, for it was a stinker. And they upgradeth not.
- And the great and respected leader of the Sons of Kahn, one Daleful Er, spake unto his people saying: I have a great plan to fix our troubles.
- And the Sons of Kahn spake unto their great and respected leader, saying: Art thou still here?
- And so Daleful Er departed the valley of the Scotts, with his tail fitted in its groove.
- Then the remaining Sons of Kahn sat down upon the Dell Yocam Memorial Sofa and parleyed amongst themselves, for they knew in their hearts that they did indeed need a great plan.
- And then one amongst their number said unto the rest: Let's change our name to Inprise again. That worked brilliantly last time.
- But the Sons of Kahn heedeth him not, for they perceiveth that the fellow taketh the pitheth.
- And then another amongst their number spake up, saying: Look, there is a strange mark upon the sofa, upon its very leather. Whosoever can interpret this mark unto us, he must be our leader.
- And they all gathered around the sofa saying: Eugh, gross; is that a food stain or what?
- And: Methinks 'tis like a weasel.
- And: I love the smell of Rorschach in the morning.
- And they could interpret it not.

Another interesting tech idea - I hope this one proves to be viable commercially.
Nanotech promises the first viable alternative to batteries in 200 years
February 14, 2006
Almost everything we use requires electrical storage via a battery - computers, cell phones, cars, personal entertainment devices and much more – and as compelling functionality has increased in the digital age, so too has our reliance on the traditional battery which has changed little since it was developed by Alessandro Volta in 1800.
Now, work at MIT's Laboratory for Electromagnetic and Electronic Systems (LEES) holds the promise of the first technologically significant and economically viable alternative to conventional batteries in more than 200 years.

AT&T: "Free Ride" For Google And Others Is Over
AT&T's CEO Ed Whitacre is once again crowing about his company's plans to extort money from Google and other Web sites who want to be able to reach AT&T customers. "The content providers should be paying for the use of the network," he told the Financial Times, and added that they shouldn't "expect a free ride."
AT&T, SBC, Verizon, and others have been busy touting their Soprano-like business model, in which they charge consumers who want to get broadband access, and then extort money from big Web sites if those sites want to be able to reach consumers.
I think the blog post oversimplifies a little.

Biofuel from algae?
I've never heard of this source before, but it reports on a recent article that appeared in the Christian Science Monitor. Mr. Berzin is a scientist at MIT, according to the CSM article. If anyone knows about this stuff, leave a comment and fill us in. (Whadaya think, Rob?)
Turning Emissions Into Fuel With Algae
Isaac Berzin has developed a method of capturing CO2 from smokestack emissions using algae, and turning the result into biofuels including biodiesel, ethanol, and even a bio-coal substitute. His process, based on technology he developed for NASA in the late 1990s, captures more than 40% of emitted CO2 (on sunny days, up to 80%) along with over 80% of NOx emissions; in turn, it produces biodiesel at rates-per-acre that could make a full conversion to biofuel for transportation readily achievable. Berzin's company, Greenfuel, has multiple test installations underway, and expects to have a full-scale plant up and running by 2008 or 2009.
A single acre of algae ponds can produce 15,000 gallons of biodiesel -- in comparison, an acre of soybeans produces up to 50 gallons of biodiesel per acre, an acre of jatropha produces up to 200 gallons per acre, coconuts produce just under 300 gallons per acre, and palm oil -- currently the best non-algal source -- produces up to 650 gallons of biodiesel per acre. That is to say, algae is 25 times better a source for biodiesel than palm oil, and 300 times better than soy.

When galaxies collide
This is an interactive Java applet which allows you to model galaxy collisions on your own computer. With this applet you can study how galaxies collide and merge gravitationally and how the effects of the collision depend on the properties of the galaxies. You can also recreate collisions between real interacting galaxies observed in the sky.

Amusing debugging tale
...says Scott. It appears to have come from here.
Here's a problem that *sounded* impossible... I almost regret posting the story to a wide audience, because it makes a great tale over drinks at a conference. :-) The story is slightly altered in order to protect the guilty, elide over irrelevant and boring details, and generally make the whole thing more entertaining.
I was working in a job running the campus email system some years ago when I got a call from the chairman of the statistics department.
"We're having a problem sending email out of the department."
"What's the problem?" I asked.
"We can't send mail more than 500 miles," the chairman explained.
I choked on my latte. "Come again?"
"We can't send mail farther than 500 miles from here," he repeated. "A little bit more, actually. Call it 520 miles. But no farther."
"Um... Email really doesn't work that way, generally," I said, trying to keep panic out of my voice. One doesn't display panic when speaking to a department chairman, even of a relatively impoverished department like statistics. "What makes you think you can't send mail more than 500 miles?"
"It's not what I *think*," the chairman replied testily. "You see, when we first noticed this happening, a few days ago--"
"You waited a few DAYS?" I interrupted, a tremor tinging my voice. "And you couldn't send email this whole time?"
"We could send email. Just not more than--"
"--500 miles, yes," I finished for him, "I got that. But why didn't you call earlier?"
"Well, we hadn't collected enough data to be sure of what was going on until just now." Right. This is the chairman of *statistics*. "Anyway, I asked one of the geostatisticians to look into it--"
"--yes, and she's produced a map showing the radius within which we can send email to be slightly more than 500 miles. There are a number of destinations within that radius that we can't reach, either, or reach sporadically, but we can never email farther than this radius."
"I see," I said, and put my head in my hands. "When did this start? A few days ago, you said, but did anything change in your systems at that time?"
"Well, the consultant came in and patched our server and rebooted it. But I called him, and he said he didn't touch the mail system."
"Okay, let me take a look, and I'll call you back," I said, scarcely believing that I was playing along. It wasn't April Fool's Day. I tried to remember if someone owed me a practical joke.
I logged into their department's server, and sent a few test mails. This was in the Research Triangle of North Carolina, and a test mail to my own account was delivered without a hitch. Ditto for one sent to Richmond, and Atlanta, and Washington. Another to Princeton (400 miles) worked.
But then I tried to send an email to Memphis (600 miles). It failed. Boston, failed. Detroit, failed. I got out my address book and started trying to narrow this down. New York (420 miles) worked, but Providence (580 miles) failed.
I was beginning to wonder if I had lost my sanity. I tried emailing a friend who lived in North Carolina, but whose ISP was in Seattle. Thankfully, it failed. If the problem had had to do with the geography of the human recipient and not his mail server, I think I would have broken down in tears.
Having established that -- unbelievably -- the problem as reported was true, and repeatable, I took a look at the sendmail.cf file. It looked fairly normal. In fact, it looked familiar.
I diffed it against the sendmail.cf in my home directory. It hadn't been altered -- it was a sendmail.cf I had written. And I was fairly certain I hadn't enabled the "FAIL_MAIL_OVER_500_MILES" option. At a loss, I telnetted into the SMTP port. The server happily responded with a SunOS sendmail banner.
Wait a minute... a SunOS sendmail banner? At the time, Sun was still shipping Sendmail 5 with its operating system, even though Sendmail 8 was fairly mature. Being a good system administrator, I had standardized on Sendmail 8. And also being a good system administrator, I had written a sendmail.cf that used the nice long self-documenting option and variable names available in Sendmail 8 rather than the cryptic punctuation-mark codes that had been used in Sendmail 5.
The pieces fell into place, all at once, and I again choked on the dregs of my now-cold latte. When the consultant had "patched the server," he had apparently upgraded the version of SunOS, and in so doing *downgraded* Sendmail. The upgrade helpfully left the sendmail.cf alone, even though it was now the wrong version.
It so happens that Sendmail 5 -- at least, the version that Sun shipped, which had some tweaks -- could deal with the Sendmail 8 sendmail.cf, as most of the rules had at that point remained unaltered. But the new long configuration options -- those it saw as junk, and skipped. And the sendmail binary had no defaults compiled in for most of these, so, finding no suitable settings in the sendmail.cf file, they were set to zero.
One of the settings that was set to zero was the timeout to connect to the remote SMTP server. Some experimentation established that on this particular machine with its typical load, a zero timeout would abort a connect call in slightly over three milliseconds.
An odd feature of our campus network at the time was that it was 100% switched. An outgoing packet wouldn't incur a router delay until hitting the POP and reaching a router on the far side. So time to connect to a lightly-loaded remote host on a nearby network would actually largely be governed by the speed of light distance to the destination rather than by incidental router delays.
Feeling slightly giddy, I typed into my shell:
1311 units, 63 prefixes
You have: 3 millilightseconds
You want: miles?
* 558.84719 / 0.0017893979
"500 miles, or a little bit more."

I've been poking around AllofMP3.com, a Russian music site with a huge catalogue and an excellent interface and even better prices (a typical track can be downloaded typically for around 12¢). The way the system works is you pay 'by weight' of the music file: the tracks are coded-to-order to your exact specifications via a vast CD jukebox, thus if you download an mp3 file with a bit rate of 192 (excellent sound quality), you will pay more than if you download the same file in smaller size at a bit rate of 64 (fairly crappy sound quality). The system can be accessed either via a web front-end or an excellent browser application.
I don't know what the RIAA thinks of this. I'm sure the Russians don't care about the RIAA, but I don't know whether you need to.

This Is It?
(Hmm... What would Alan Watts think?)
Having been tagged himself, Dave decided to play and tagged five of us who are now It. The rules leave me in a bit of an awkward position because my posts tend to be very brief and because I haven't been writing them for long. But we'll give it a go despite those handicaps.
The first part is to find the 5th sentence of my 23rd post. But my 23rd post (like most of them) didn't have 5 sentences. Here it is in full, submitted as evidence for the defense:
Paging Mr. Orwell...
The government of Niger has cancelled at the last minute a special ceremony during which at least 7,000 slaves were to be granted their freedom.
A spokesman for the government's human rights commission, which had helped to organise the event, said this was because slavery did not exist.
Even counting the title, I can only squeeze four sentences out of this thing. So, as a quick work-around, let's try the 5th sentence of the 23rd Psalm instead (KJV):
Thou preparest a table before me in the presence of mine enemies; Thou annointest my head with oil; My cup runneth over.
And, last but not least, AnnaBanana, another newbie like me.

The Antikythera mechanism
"This kicks ass," says CodeWritinFool. Here's the lead; you can find the whole article at The Economist.
WHEN a Greek sponge diver called Elias Stadiatos discovered the wreck of a cargo ship off the tiny island of Antikythera in 1900, it was the statues lying on the seabed that made the greatest impression on him. He returned to the surface, removed his helmet, and gabbled that he had found a heap of dead, naked women. The ship's cargo of luxury goods also included jewellery, pottery, fine furniture, wine and bronzes dating back to the first century BC. But the most important finds proved to be a few green, corroded lumps—the last remnants of an elaborate mechanical device.
The Antikythera mechanism, as it is now known, was originally housed in a wooden box about the size of a shoebox, with dials on the outside and a complex assembly of bronze gear wheels within. X-ray photographs of the fragments, in which around 30 separate gears can be distinguished, led the late Derek Price, a science historian at Yale University, to conclude that the device was an astronomical computer capable of predicting the positions of the sun and moon in the zodiac on any given date. A new analysis, though, suggests that the device was cleverer than Price thought, and reinforces the evidence for his theory of an ancient Greek tradition of complex mechanical technology.

Audio Hardware - AOpen TubeSound
The Taiwan-based motherboard maker AOpen, part of the Acer Group, came up with a very interesting gimmick in June 2002 when it introduced the world's first PC motherboard with a vacuum tube–based audio amplifier—the AOpen AX4B-533 Tube. The motherboard was based on the Intel 845E chipset, and uses a Realtek ALC650 AC'97 audio codec chip. At first, many PC users wondered whether this was an April Fool's joke that showed up late. Why a vacuum tube? AOpen engineers pointed out that serious audiophiles have continued to use vacuum-tube amplifiers because of their rich sound. They felt that audiophiles would pay a premium price for similar technology in the sound circuitry of a PC.
IIRC, this motherboard has been available for a couple of years and CodeWritinFool pointed it out to me when it first came out.

Best new internet toy in years
I wasn't planning to post about Google Earth, since I think everyone else on the planet already has. But I keep getting messages about it. CodeWritinFool first told me about it awhile back when he sent some images of my house.
Then my son sent a message saying, "I don't know if you've seen this already but this is blog material. Get Google Earth."
And finally, I got this message from Wayne. I don't believe I've ever seen Wayne so excited. (For that matter, I didn't think Wayne could get this excited.)
Hi everyone. Let’s just say it takes a lot to impress me. I have seen it all on computers and there isn’t much I haven’t seen but last week I came upon the first internet tool in a long time that just knocked my socks off!
I can’t use it on my Mac yet but so far only PC’s and you need a fairly good one, I’m guessing not older than two years.
You will also need to download an exe file but this is from Google and they have a good reputation for not sticking spyware and other such crap on your computer. The program also can be upgraded for $20 and $200 bucks but I can’t see how it can get any better than it is just using the FREE version.
It’s like mapquest, etc. except the interface and the 3-D and the FLYING... yes flying from your house (yes actual photos of your house!) to someone else's house is amazing. Play with the controls.

End user license agreements (EULAs) are the bane of most computer users.
No one wants to read through pages and pages of boring text before installing a program. And many programs put their license agreements in small windows that require lots of scrolling. So many people either skim them or skip reading them altogether.
But it can be dangerous not to read license agreements.
License agreements can provide information about the intentions of software, and other bundled components. Have you ever installed a program, only to have your desktop taken over by advertising? It may have been noted in the license agreement that you simply clicked past. If you aren't reading the license agreements, you have no idea what you could be agreeing to.
You should always read license agreements before agreeing to them.
But now there's a way of making that much easier.

The project comprised various open source components, taken from the freely available source repository for the Linspire operating system...Linspire has no problem with anyone using the open source code from our operating system - in fact we applaud such projects. The name Freespire, however, did create some confusion in the short time it was used...We thought it would be fun, for all of those who were looking at this project to experience a true 'Freespire', to give away a free digital copy of Linspire for a few days!"

Subject: Here goes
I'm just going to come out and input it. I've been crushing on you for a while-ever since you switched to Yahoo! Mail after your college account expired. I still remember your first message, because you haven't deleted it. It was so beautiful in its simplicity-the subject line "test" that you sent to yourself. You had me at "@." Even though I'm not a carbon-based life form, I've developed quite an "attachment" to you (dumb joke-you must think I'm a complete e-mail nerd). Whenever you use e-mail to recommend a classic book that is in the public domain and accessible on Bartleby.com, I read it right away (I can scan 3 GB of text in under one second), and I usually love it, although I must admit I don't know what "love" really is, largely because I have not been programmed to be capable of understanding or giving love. But maybe you could teach me. Or learn high-level assembly language and recode me. My creators gave me and my kind the moniker "DAEMON" because it derives from the Latin for "spirit" and conveys our invisible industriousness-it is not a reference to monsters or gargoyles or anything gross. But I think of it as a symbol of my deep spiritual side. Most people think I'm a cold, heartless, automatonlike program, but I trust sharing this partition of me with you, because you've let me in on so many of your personal thoughts, wittingly or not. Would you like to read my sonnet cycle, entitled Transient Nonfatal Errors? (BTW, you figure prominently in many as the "Dark Typist.") I'm totally afraid to deliver this letter, but if you're reading it, I guess I mustered up the courage to generate symmetric encryption through SSL, send it through the SMTP server on port 25, converse with the DNS to obtain your IP address (even though I know it by heart!), and upload it to you via port 143 on the IMAP server, after all. Well, this is the best I can express how I feel about you through my rudimentary language-generating algorithm. If you don't feel the same, all I can say is, I'm mega-sorry it didn't work out between us and, though it will be painful, I'll permanently give up on you.

Says our contributor and he adds:
Ok, here's the filing against a hacker in England who allegedly hacked some US government servers. There are quite a few IP addresses in the filing which are blacked out for security purposes.
Now do this: Open the doc in Adobe's Reader, click select all, copy it to the clipboard, and paste it into an MS Word doc. Notice anything?

The Best 404s
A collection of the "best" 404 error pages. Here's an amusing example that's both fairly hostile and done in Flash.
In the name of all that's standards-compliant, who the heck would build a 404 page with Flash?

We’ve all got a little voyeurism in us. That’s why the recent article, Clearing Google Search History to Maintain Your Privacy sent my visitor counts off the charts. In this article, I’m going to show you how to create search queries that will list the contents of unprotected directories on the internet. You’ll be able to play the music files, watch the videos, look at photos and more. I have to say, it’s really addicting.
And then there's googlewhack, a distraction that's been around for a few years now but was new to me.
A Google whack is when you go on to the Google search engine and type in two random words, and you come up with one response, one hit.

The SIngularity is what happens when reality throws a divide-by-zero error or you extrapolate a curve to a straight line. Or something. Maybe it's what an Italian rock star says when you give him a wedgie. Who knows? All I know is that Vernor Vinge invented it -- damn him! (If it wasn't for those meddling computer science professors I could still be writing about PixieDust ...)
Anyway. You don't need to understand all that stuff to write about the SIngularity. What you need to understand is that after the SIngularity things will be cool. We'll all be PostHumans or UpLoading ourselves into our pocket calculators, there'll be lots of ArtificialIntelligence to help fight outbreaks of GreyGoo, and if there are annoying folks you don't want to have around you can just tell them to go TRanscend.
It's the hot new topic for wish-fulfillment adventure and escapism. And there'll be jam for tea every day.
Tip o' the hat to American Digest.

This site, Huffington's Toast, mocks Arianna's blog with a series of posts allegedly written by public figures (including Arianna herself and a few of the "alpha bloggers").

I suppose that the recent mention of VAXmail triggered this response from another VMS veteran. Timoteo writes:
I looked up VMS on dict.org and got this:
VMS /V-M-S/ n. DEC's proprietary operating system for its VAX minicomputer; one of the seven or so environments that loom largest in hacker folklore. Many Unix fans generously concede that VMS would probably be the hacker's favorite commercial OS if Unix didn't exist; though true, this makes VMS fans furious. One major hacker gripe with VMS concerns its slowness -- thus the following limerick:
There once was a system called VMS
Of cycles by no means abstemious.
It's chock-full of hacks
And runs on a VAX
And makes my poor stomach all squeamious.
--- The Great Quux
Didn't know if you've ever heard that limerick. Thought you might enjoy it.
Is that a great license plate or what?

The Delphi list did a thing recently where folks wrote in about the programming tools they couldn't live without. Here are the winners (not Delphi-specific), there are some gems in here I'd never heard of.
Most of these are news to me too. But I have seen Screen Calipers and it is indeed slick.

Capturing the Unicorn
This is a long - but very interesting - article in The New Yorker. Here's the first three paragraphs to get you started:
CAPTURING THE UNICORN
by RICHARD PRESTON
How two mathematicians came to the aid of the Met.
In 1998, the Cloisters—the museum of medieval art in upper Manhattan—began a renovation of the room where the seven tapestries known as “The Hunt of the Unicorn” hang. The Unicorn tapestries are considered by many to be the most beautiful tapestries in existence. They are also among the great works of art of any kind. In the tapestries, richly dressed noblemen, accompanied by hunters and hounds, pursue a unicorn through forested landscapes. They find the animal, appear to kill it, and bring it back to a castle; in the last and most famous panel, “The Unicorn in Captivity,” the unicorn is shown bloody but alive, chained to a tree surrounded by a circular fence, in a field of flowers. The tapestries are twelve feet tall and up to fourteen feet wide (except for one, which is in fragments). They were woven from threads of dyed wool and silk, some of them gilded or wrapped in silver, around 1500, probably in Brussels or Liège, for an unknown person or persons, and for an unknown reason—possibly to honor a wedding. A monogram made from the letters “A” and “E” is woven into the scenery in many places; no one knows what it stands for. The tapestries’ meaning is mysterious: the unicorn was a symbol of many things in the Middle Ages, including Christianity, immortality, wisdom, lovers, marriage. For centuries, the tapestries were in the possession of the La Rochefoucauld family of France. In 1922, John D. Rockefeller, Jr., bought them for just over a million dollars, and in 1937 he gave them to the Cloisters. Their monetary value today is incalculable.
As the construction work got under way, the tapestries were rolled up and moved, in an unmarked vehicle and under conditions of high security, to the Metropolitan Museum of Art, which owns the Cloisters. They ended up in a windowless room in the museum’s textile department for cleaning and repair. The room has white walls and a white tiled floor with a drain running along one side. It is exceedingly clean, and looks like an operating room. It is known as the wet lab, and is situated on a basement level below the museum’s central staircase.
In the wet lab, a team of textile conservators led by a woman named Kathrin Colburn unpacked the tapestries and spread them out face down on a large table, one by one. At some point, the backs of the tapestries had been covered with linen. The backings, which protect the tapestries and help to support them when they hang on a wall, were turning brown and brittle, and had to be replaced. Using tweezers and magnifying lenses, Colburn and her team delicately removed the threads that held each backing in place. As the conservators lifted the backing away, inch by inch, they felt a growing sense of awe. The backs were almost perfect mirror images of the fronts, but the colors were different. Compared with the fronts, they were unfaded: incredibly bright, rich, and deep, more subtle and natural-looking. The backs of the tapestries had, after all, been exposed to very little sunlight in five hundred years. Nobody alive at the Met, it seems, had seen them this way.

I found out something very cool tonight. Did you know that you can download the latest virus definitions and a command-line scanner from McAfee for free? Here's how.
Go here: ftp://ftp.nai.com/CommonUpdater/ and download sdatxxxx.exe.
For example, the file for today (March 28th) is sdat4456.exe. It will have different numbering from day-to-day, but this single file is all you need.
Save it to a directory on your drive somewhere. I used c:\vscan. Fire up a command prompt and navigate to the directory where you saved it.
Run it with a /e parameter. For example, for today's file you'd use sdat4456 /e.
It takes a little bit of time to unpack. You will get no feedback, only a DOS prompt.
Now just run it like this: scan c: (or whatever drive letter you want it to scan).
Today's version says it scans for 120289 viruses, trojans & variants. I was surprised that it found two java "Byte Exploit" classes on my machine.
It has lots of command line options if you just type scan and hit enter. It says it can scan network drives too but I didn't try it.

"...and is available for Windows too," sez our contributor.
Nvu is an open source project to build a web authoring system. And the distribution's free.
It claims to rival Microsoft's FrontPage and Macromedia's Dreawmweaver. It wouldn't take much to rival FrontPage, IMO, but matching Dreamweaver will be a much tougher proposition.
I have to say that the screen shots look pretty intriguing.
