"It's stupidity. It's worse than stupidity: it's a marketing hype campaign."
Ellison:
"The computer industry is the only industry that is more fashion-driven than women's fashion. Maybe I'm an idiot, but I have no idea what anyone is talking about. What is it? It's complete gibberish. It's insane. When is this idiocy going to stop?"
As of this blog posting, exactly 900 days remain until the end of the Internet, or at least the exhaustion of IPv4 registry allocations. And you don’t have to take my word for it, even the normally staid London Times and Fox News proclaimed, “Internet meltdown ... The world is heading for a digital doomsday”.
Heady stuff.
Of course, IPv6 (or the new IPv4) was supposed to take care of all of this — billions of billions of new IP addresses, hardened security built in from the start, and an elegant new architecture to replace all of IPv4’s hacks.
A perceptual hash is a fingerprint of an audio, video or image file that is mathematically based on the audio or visual content contained within. Unlike usual hash functions that rely on the avalanche effect of small changes in input leading to drastic changes in the output, perceptual hashes are "close" to one another if the inputs are visually or auditorily similar. As a result, perceptual hashes must also be robust enough to take into account transformations that could have been performed on the input, such as rotation, skew, altering contrast, etc. All of these properties make perceptual hashes a very interesting computer science problem to study.
What is pHash?
pHash is an open source library released under the GPLv3 license that implements several perceptual hashing algorithms and provides a C++ API to use those functions in your own programs.
As networks become ever more complex, securing them becomes more and more difficult. The solution is visualization. Using today’s state-of-the-art data visualization techniques, you can gain a far deeper understanding of what’s happening on your network right now. You can uncover hidden patterns of data, identify emerging vulnerabilities and attacks, and respond decisively with countermeasures that are far more likely to succeed than conventional methods.
In Applied Security Visualization, leading network security visualization expert Raffael Marty introduces all the concepts, techniques, and tools you need to use visualization on your network. You’ll learn how to identify and utilize the right data sources, then transform your data into visuals that reveal what you really need to know. Next, Marty shows how to use visualization to perform broad network security analyses, assess specific threats, and even improve business compliance.
He concludes with an introduction to a broad set of visualization tools. The book’s CD also includes DAVIX, a compilation of freely available tools for security visualization.
WaveScope is a system for developing distributed, high-rate applications that need to process streams of data from various sources (e.g., sensors) using a combination of signal processing and database (event stream processing) operations. The execution environment for these applications ranges from embedded sensor nodes to multicore/multiprocessor servers.
Beautiful Code, Compelling Evidence: Functional Programming for Information Visualization and Visual Analytics

OpenGL is powerful, but it can also be more complicated than actually necessary. For applications involving 2D graphics, a low amount of interactivity, and a smaller amount of data, it would be simpler not to bother with the video card and the rendering pipeline. Additionally, some visualizations are meant for print form. The Gnome Foundation’s Cairo 2D graphics toolkit is perfect for these applications. As luck would have it, Haskell also has an excellent binding to Cairo.
Three other things make Haskell ideally suited to information visualization and visual analytics: a well-thought out and extensible library of generic data structures, lazy evaluation, and the separation of data transformation code from input/output inherent in a pure functional programming language. Visualizations written in Haskell tend naturally to break up into portions of reusable and visualization specific code. Thus, programs for visualization written in Haskell maintain readability and reusability as well or better than Python, but do not suffer the performance problems of an interpreted language.
For much the same reason as Simon Peyton-Jones put together Tackling the Awkward Squad, I have put together these lecture notes. I hope these will bring a programmer interested in visualization and open to the aesthetic advantages of functional programming up to speed on both topics.
H-P says it's working on an array of products, including notebooks, that use the very same type of finger-tapping interface popularized by Apple Inc.'s iPhone. H-P's so keen on the idea that it says it's trying to get touch-enabled notebook computers on the market within the next 18 months.
"We're focused on recognizing the potential of touch now," said Phil McKinney, the chief technology officer for the company's laptop-making Personal Systems Group. "We see touch as the almost preferred method for nontechnical users."
