These are four of my all-time favorite sf novels; to have them back in print is cause for celebration -- a CC release on top of that? HEAVEN. (Insert "zero-day warez" joke here)

It starts with Software, where rebel robots bring immortality to their human creator by eating his brain. Software won the first Philip K. Dick Award.

In Wetware, the robots decide to start building people­--and people get strung out on an insane new drug called merge. This cyberpunk classic garnered a second Philip K. Dick award.

By Freeware, the robots have evolved into soft plastic slugs called moldies­--and some human "cheeseballs" want to have sex with them. The action redoubles when aliens begin arriving in the form of cosmic rays.

And with Realware, the humans and robots reach a higher plateau.

Gemini's implications extend to the real world. "There's a fascination with the complexity that is coming out of these incredibly simple rules," says Susan Stepney, a computer scientist at the University of York, UK, who ran Gemini inside Life, at New Scientist's behest. "Eventually that leads on to biology, putting simple atoms together to make complex life."

Because Wade's replicator copies itself piece by piece, it is analogous to a photocopier rather than a living cell, she says. But it still has implications for understanding life. "The fact that it's doing it differently from biology is in itself interesting, because it shows there are multiple ways of solving the same problem. It's a very impressive technical achievement."

It's doing it differently from biology, showing there are multiple ways of solving the same problem Stephen Wolfram, famous for championing cellular automata as a replacement for scientific equations, disputes Gemini's relevance to living cells. He says that feeding a program to a universal constructor merely to create a self-replicating creature - Wade's approach, and Von Neumann's original suggestion - is overkill. He points to a much simpler example, a one-dimensional cellular automaton known as "rule 90" that will duplicate any starting line of cells after a certain number of steps.

Rather than contributing to our understanding of life, Wolfram says Wade's discovery could help devise ways to build a molecular-scale computer, starting from tiny components like the cells in Life. "This discovery is helping us understand the world of constructing things from dumb components," he says.

Intel was the only game in town for about a year, but fortunately for us consumers, the competition finally caught up. The new Indilinx controller models, such as this Crucial 128 GB SSD, are just as fast as the X25-M. And, best of all, they’re cheaper, while also offering a not-insubstantial bump to 128 GB of storage!

I picked this model up for $325 plus tax and shipping. And, frankly, I was blown away by the performance difference compared to the 300 GB Velociraptor I had in my system before. That drive is not exactly chopped liver; it’s incredibly fast by magnetic platter drive standards. But it’s beyond slow next to the latest SSDs.

FLAG, a fiber-optic cable now being built from England to Japan, is a skinny little cuss (about an inch in diameter), but it is 28,000 kilometers long, which is long even compared to really big things like the planet Earth. When it is finished in September 1997, it arguably will be the longest engineering project in history. Writing about it necessitates a lot of banging around through meatspace. Over the course of two months, photographer Alex Tehrani and I hit six countries and four continents trying to get a grip on this longest, fastest, mother of all wires. I took a GPS receiver with me so that I could have at least a general idea of where the hell we were. It gave me the above reading in front of a Chinese temple around the corner from the Shangri-La Hotel in Penang, Malaysia, which was only one of 100 peculiar spots around the globe where I suddenly pulled up short and asked myself, “What the hell am I doing here?”

The author of almost 100 books, Mr. Clarke was an ardent promoter of the idea that humanity’s destiny lay beyond the confines of Earth. It was a vision served most vividly by “2001: A Space Odyssey,” the classic 1968 science-fiction film he created with the director Stanley Kubrick and the novel of the same title that he wrote as part of the project.

His work was also prophetic: his detailed forecast of telecommunications satellites in 1945 came more than a decade before the first orbital rocket flight.

Other early advocates of a space program argued that it would pay for itself by jump-starting new technology. Mr. Clarke set his sights higher. Borrowing a phrase from William James, he suggested that exploring the solar system could serve as the “moral equivalent of war,” giving an outlet to energies that might otherwise lead to nuclear holocaust.

It had occurred to me that perhaps with an insane amount of perseverance, it might be possible to build a whole computer that runs on marbles. My second marble machine was however much less based on logic – more on just making lots of noise.

But a few months ago, I had an idea as to how the divide by two mechanisms from my first marble machine could be cascaded together to actually function as a sort of adder or counter. Once I had that idea, I knew I had to try it at some point, and recently, I finally got around to building my marble binary adding machine.

The core of the invention is a modification of the divide by two flipflop to retain the marble that falls off the right side, and retain it until the flipflop is flipped to the left by the next marble. See small diagram above right. The retention of this extra marble allows the state of the marble accumulator to be dumped. The adder would just as well add without it, but the number would have to be read off by the angle of the rockers, rather than have the device dump the count out. Really, if such an adder were integrated into a hypothetical marble computer, reading out the result as a series of marbles would be an essential element.

In Where Wizards Stay Up Late, Hafner and Lyon take us all the way back to the earliest days of computer networking. We are introduced to all of the central figures that were responsible for building the precursors to the internet we know today. In contrast with the rapid growth we see now, the early days seem glacial. The equipment was primitive and had to be custom built. No one had any idea initially how they could connect disparate computers together and make them talk to one another. The fact that the protocols that they eventually came up with are still in use on the internet today, and have managed to survive its explosive growth, is a testament to the genius and vision of these pioneers. The authors have managed to capture not only the tough technical hurdles that needed to be overcome, but also the motivations and the leaps of insight of the people involved during this historic time. This is an enjoyable book that moves at a fairly brisk pace, but I wouldn’t have minded seeing a little more of the technical details.

This book contains 32 interviews with founding members of different tech startups. Most of the interviews follow the same general format: how they got their idea, their first steps in forming a company, how they executed their plans, and what major obstacles they encountered. I think the author captures the character of many of these startups quite nicely in the introduction to the book: “In its plain form, productivity looks so weird that it seems to a lot of people to be ‘unbusinesslike.’ But if early-stage startups are unbusinesslike, then the corporate world might be more productive if it were less businesslike.”

Far from being a dry business book, the stories are engaging and inspiring. There are lots of great insights to be found in these interviews. Max Levchin tells us how much effort they spent to find ways to combat credit card fraud at PayPal, which became their main advantage as their competitors bled money from chargebacks. Mike Lazaridis was able to leverage their technical skills at Research In Motion to build a robust and reliable system for delivering wireless email. Philip Greenspun’s interview is a cautionary tale on what can happen when venture capitalists bring in incompetent managers to run your company.

Founders at Work is a good read for anyone curious about turning a wild idea into a sustainable business.

The good thing about this hack is that you load it off your of memory card every time you turn your camera on (in some cases you can also enable auto-loading) so the original firmware of the camera is not touched, making this a fairly safe hack.

Q. What does the HDK firmware do?

A. After loading of HDK firmware you can get the following functionality:

• Shooting in RAW
• Live histogram (RGB, blended, luminance and for each RGB channel)
• Zebra mode (blinking highlights and shadows)
• DOF-calculator
• Battery indicator
• Scripts execution (exposure/focus/… bracketing, intervalometer and more)
• File browser
• Text reader
• Calendar
• Some fun tools and games

Back in 1985, Wim Van Eck proved it was possible to tune into the radio emissions produced by electromagentic coils in a CRT display and then reconstruct the image. The practice became known as Van Eck Phreaking, and NATO spent a fortune making its systems invulnerable to it. It was a major part of Neal Stephenson’s novel Cryptonomicon.

CRTs are now well on the way to being history. But Kuhn has shown that eavesdropping is possible on flat panel displays too. It works slightly differently. With a flat panel display the aim is to tune into the radio emissions produced by the cables sending a signal to the monitor. The on-screen image is fed through the cable one pixel at a time. Because they come through in order you just have to stack them up. And Kuhn has worked out how to decode the colour of each pixel from its particular wave form.

Hype is the coin of the realm in the technology business. If you listen to vendors and the media, it may sometimes seem as though every new product, service, concept or even security threat will be the Next Big Thing. Some live up to all the fuss, but many don’t — and some fail spectacularly.

As I said earlier, DVD-R sucks for data preservation for three reasons: inferior error correction, inferior ‘wobble’ tracking, and the fact its data writing methods look like an un-needed halfway point between CD-R and DVD+R. The wobble tracking I shall explain first, then the error corrections method, then the specifics of ATIP/pre-pit/ADIP optimum power settings.

I’ve been a software guy all my life. However, I was always fascinated by electronics, and part of my success as a programmer was due to my thorough understanding of how computers work.

Back in 1999, I put that understanding to the ultimate test: I actually designed, and built, a simple but functional 4-bit computer from low-level electronic components (TTL logic gates.) Although this machine has less then one tenth of a percent of the speed and one millionth of the memory of a modern Pentium system, not to mention that its “user interface” is just a set of miniature switches and blinking LED lights, I still consider this a proud accomplishment.

The most popular locking mechanism in the world utilizes the pin tumbler design, first developed 4000 years ago in Egypt and then rediscovered and perfected a century and a half ago by Linus Yale. There are billions of these locks in the world and they come in all sizes, configurations, and security ratings. Some are secure; most are not, and even some high security rated cylinders can be easily compromised. All that is required to open many times of pin tumbler cylinders — the kind of lock that probably keeps the bad guys out of your home — is a bump key and a tool for creating a bit of force. The bump key shown above opens an extremely popular five pin lock, and the plastic bumping tool is produced by Peterson manufacturing, although many others are now being offered for sale. With these two cheap implements, anyone — and I do mean anyone — can get into your home or business in a matter of seconds.

Red Lambda says that cGrid monitors “a large variety of different P2P clients, in addition to other avenues of file-sharing including Windows file sharing, FTP, IM, and others,” and that cGrid does not perform content inspection but instead focuses on the behavior of the protocols being monitored. But the company does not expand on how it differentiates between legitimate uses of those technologies and illegal ones, raising questions of its effectiveness in an academic setting where students may be using P2P and other services potentially flagged by the system for legitimate, academic reasons.
