via Nova Spivack: It doesn't simply return documents that (might) contain the answers, like Google does, and it isn't just a giant database of knowledge, like the Wikipedia. It doesn't simply parse natural language and then use that to retrieve documents, like Powerset, for example. Instead, Wolfram Alpha actually computes the answers to a wide range of questions -- like questions that have factual answers such as "What is the location of Timbuktu?" or "How many protons are in a hydrogen atom?," "What was the average rainfall in Boston last year?," "What is the 307th digit of Pi?," or "what would 80/20 vision look like?"

Inductive reasoning at it's finest.
In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings. Developed by Cornell researchers, the program deduced the natural laws without a shred of knowledge about physics or geometry. The research is being heralded as a potential breakthrough for science in the Petabyte Age, where computers try to find regularities in massive datasets that are too big and complex for the human mind. (See Wired magazine's July 2008 cover story on "The End of Science.") "One of the biggest problems in science today is moving forward and finding the underlying principles in areas where there is lots and lots of data, but there's a theoretical gap. We don't know how things work," said Hod Lipson, the Cornell University computational researcher who co-wrote the program. "I think this is going to be an important tool." Condensing rules from raw data has long been considered the province of hu

Useful Tutorials on Linux and UNIX for Beginners and Experts AlikeOfficial Google Research Blog: Large-scale graph computing at Google
I want one of these! "We have created scalable infrastructure, named Pregel, to mine a wide range of graphs. In Pregel, programs are expressed as a sequence of iterations. In each iteration, a vertex can, independently of other vertices, receive messages sent to it in the previous iteration, send messages to other vertices, modify its own and its outgoing edges' states, and mutate the graph's topology (experts in parallel processing will recognize that the Bulk Synchronous Parallel Model inspired Pregel). Currently, Pregel scales to billions of vertices and edges, but this limit will keep expanding. Pregel's applicability is harder to quantify, but so far we haven't come across a type of graph or a practical graph computing problem which is not solvable with Pregel. It computes over large graphs much faster than alternatives, and the application programming interface is easy to use. Implementing PageRank, for example, takes only about 15 lines of code. "
So many things to learn and apply in business deals.

Quants come in three basic varieties. 1. Structurers: people who price complex financial instruments. 2. Risk managers people who manage portfolio risk 3. Quant traders people who use statistics to make money by buying and selling most quants are structurers. Of course, there is often bleed over between these varieties -but it’s a useful taxonomy for looking for work. I’ve done a little of all three at this point (very little, honestly), and have always liked quant trading problems more than the other two varieties. It’s the most ambitious, and the most likely to net you a career outside of a large organization (go me: Army of one!). It’s also the most mysterious, since successful quant traders don’t like to talk about what they do. Structurers and risk managers have to talk about what they do, almost by definition. Quant traders gain little from talking about their special sauce.

Briefing from The Economist (17 October 2009)10 Years of Virtual Machine Performance (Semi) Demystified | Engine Yard Blog
Since 2005, VMware and Xen have gradually reduced the performance overheads of virtualization, aided by the Moore’s law doubling in transistor count, which inexorably shrinks overheads over time. AMD’s Rapid Virtualization Indexing (RVI – 2007) and Intel’s Extended Page Tables (EPT – 2009) substantially improved performance for a class of recalcitrant workloads by offloading the mapping of machine-level pages to Guest OS “physical” memory pages, from software to silicon. In the case of operations that stress the MMU—like an Apache compile with lots of short lived processes and intensive memory access—performance doubled with RVI/EPT. (Xen showed similar challenges prior to RVI/EPT on compilation benchmarks.)100 Incredible Open Courses for the Ultimate Tech Geek - Online Courses

You may have heard about me. In the computer business I'm known as the Oregon Hermit. According to rumor, I write personal computer programs in solitude, shunning food and sleep in endless fugues of work. I hang up on important callers in order to keep the next few programming ideas from evaporating, and I live on the end of a dirt road in the wilderness. I'm here to tell you these vicious rumors are true.

I've tried to span as many subjects as possible to have a little something for everyone while limiting myself to foundational papers that have had a lasting impact on the field and are also highly readable. Some of the people (Chomsky, Shannon, Metropolis, Ulam) represented here might not consider themselves computer scientists but the papers I've included have been so important that they cannot be left out. I admit a few papers may seem like idiosyncratic picks due to my particular interest in certain areas like computer graphics and computational dynamics. There are several important papers I couldn't include due to an absence of freely available copies, e.g. Rissanen's Generalized Kraft Inequality and Arithmetic Coding.
I am looking for something clever or thought provoking that doesn't depend on too much background knowledge, and is easy to read without too much formalism/maths.

I'll have more to say on the iPad later but one can't help being struck by the volume and vehemence of apparently technologically sophisticated people inveighing against the iPad. Some are trying to dismiss these ravings by comparing them to certain comments made after the launch of the iPod in 2001: "No wireless. Les space than a Nomad. Lame.". I fear this January-26th thinking misses the point. What you're seeing in the industry's reaction to the iPad is nothing less than future shock.
I'm often saddened by the infantilising effect of high technology on adults. From being in control of their world, they're thrust back to a childish, mediaeval world in which gremlins appear to torment them and disappear at will and against which magic, spells, and the local witch doctor are their only refuges. With the iPhone OS as incarnated in the iPad, Apple proposes to do something about this, and I mean really do something about it instead of just talking about doing something about it, and the world is going mental.

"The Real Work is not formatting the margins, installing the printer driver, uploading the document, finishing the PowerPoint slides, running the software update or reinstalling the OS. "The Real Work is teaching the child, healing the patient, selling the house, logging the road defects, fixing the car at the roadside, capturing the table's order, designing the house and organising the party. "Think of the millions of hours of human effort spent on preventing and recovering from the problems caused by completely open computer systems. ... "If the iPad and its successor devices free these people to focus on what they do best, it will dramatically change people's perceptions of computing from something to fear to something to engage enthusiastically with."Cloud computing, grid computing, utility computing - list of top providers | MyTestBox.com - web software reviews, news and tips & tricks
Cloud computing means that the applications are running somewhere in the “cloud” (whether an internal network or the Internet). We, as users, don’t know and don’t care. Done right, cloud computing allows developers to develop, deploy and run applications that can easily grow in capacity (scalability), work rapidly (performance), and never – or at least rarely – fail (reliability), all without any concern as to the nature and location of the underlying infrastructure.
Cloud computing providersEveryone can build a website, but not not everyone can build a good and popular website. If you can pull it off, you can enjoy benefits like building something people are using, recognition and – sometimes – money. It can be a good business, even your full time job. But bad things can happen, and you should be prepared for it. One of those things (well, actually this is not a bad thing!) is to have spikes in traffic… maybe as a result of getting on Digg.com, Reddit.com, Google News, or another major media outlet frontpage… or getting reviewed by Techcrunch or another major technology blog.BBC NEWS | Technology | 40 years of Unix

Quoting Marissa Mayer, Google's VP of Search Products & User Experience: "You may have heard about our [directory assistance] 1-800-GOOG-411 service. Whether or not free-411 is a profitable business unto itself is yet to be seen. I myself am somewhat skeptical. The reason we really did it is because we need to build a great speech-to-text model … that we can use for all kinds of different things, including video search."

"Computers are supposed to be pretty good at this math stuff. What gives? How is it possible to produce such blatantly incorrect results from seemingly trivial calculations? Should we even be trusting our computers to do math at all?"
"Computers are awesome, yes, but they aren't infinite.. yet. So any prospects of storing any infinitely repeating number on them are dim at best. The best we can do is work with approximations at varying levels of precision that are "good enough", where "good enough" depends on what you're doing, and how you're doing it. And it's complicated to get right."4 Steps To a Professional Database Design | ProgrammerFish - Everything that's programmed!

Here at Sun, the Fallacies of Distributed Computing have long been a much-revered lesson. Furthermore, I personally think they’re pretty much spot-on. But these days, you don’t often find them coming up in conversations about building big networked systems. The reason is, I think, that we build almost everything on Web technologies, which lets get away with believing some of them.
If you’re building Web technology, you have to worry about these things. But if you’re building applications on it, mostly you don’t. ¶ Well, except for security; please don’t stop worrying about securityMac money-savers: fill up your Mac for free | News | TechRadar UK
