  • Comparison of data analysis packages: R, Matlab, SciPy, Excel, SAS, SPSS, Stata – Brendan O’Connor’s Blog – Lukas and I were trying to write a succinct comparison of the most popular packages that are typically used for data analysis. I think most people choose one based on what people around them use or what they learn in school, so I’ve found it hard to find comparative information. I’m posting the table here in hopes of useful comments.
  • Thin Film Turns Any Surface Into a Touchscreen | Gadget Lab | Wired.com – Turning your monitor into a touchscreen could some day be as simple as peel … and stick.

  • Corrupted Blood incident – Wikipedia, the free encyclopedia – The Corrupted Blood incident was a widely reported virtual plague outbreak and video game glitch found in the Blizzard Entertainment computer game World of Warcraft, a massively multiplayer online role-playing game in the Warcraft series. The plague began on September 13, 2005, when an area was introduced in a new update. One boss could cast a spell called Corrupted Blood, which would deal a certain amount of damage over a period of time, and which could be transferred from character to character. It was intended to be exclusive to this area, but players discovered ways to take it out, causing an epidemic across several servers. During the epidemic, some players would help combat the disease by volunteering healing services, while select others would maliciously spread the disease.

  • In the Next Industrial Revolution, Atoms Are the New Bits | Magazine – Here’s the history of two decades in one sentence: If the past 10 years have been about discovering post-institutional social models on the Web, then the next 10 years will be about applying them to the real world.

    This story is about the next 10 years.

    Transformative change happens when industries democratize, when they’re ripped from the sole domain of companies, governments, and other institutions and handed over to regular folks. The Internet democratized publishing, broadcasting, and communications, and the consequence was a massive increase in the range of both participation and participants in everything digital — the long tail of bits.

    Now the same is happening to manufacturing — the long tail of things.

  • [quant-ph/0204088] The Wave Function: It or Bit? – Schroedinger's wave function shows many aspects of a state of incomplete knowledge or information ("bit"): (1) it is usually defined on a space of classical configurations, (2) its generic entanglement is, therefore, analogous to statistical correlations, and (3) it determines probabilities of measurement outcomes. Nonetheless, quantum superpositions (such as represented by a wave function) define individual physical states ("it"). This conceptual dilemma may have its origin in the conventional operational foundation of physical concepts, successful in classical physics, but inappropriate in quantum theory because of the existence of mutually exclusive operations (used for the definition of concepts). In contrast, a hypothetical realism, based on concepts that are justified only by their universal and consistent applicability, favors the wave function as a description of (thus nonlocal) physical reality. The (conceptually local) classical world then appears as an illusion…
  • 9 Ways to Visualize Proportions – A Guide | FlowingData – With all the visualization options out there, it can be hard to figure out what graph or chart suits your data best. This is a guide to make your decision easier for one particular type of data: proportions.
  • Computer Laboratory – Technical reports: UCAM-CL-TR-754 – The success of many attacks on computer systems can be traced back to the security engineers not understanding the psychology of the system users they meant to protect. We examine a variety of scams and “short cons” that were investigated, documented and recreated for the BBC TV programme The Real Hustle and we extract from them some general principles about the recurring behavioural patterns of victims that hustlers have learnt to exploit.

    We argue that an understanding of these inherent “human factors” vulnerabilities, and the necessity to take them into account during design rather than naïvely shifting the blame onto the “gullible users”, is a fundamental paradigm shift for the security engineer which, if adopted, will lead to stronger and more resilient systems security.

  • Memristor – Wikipedia, the free encyclopedia – On April 30, 2008 a team at HP Labs announced the development of a switching memristor. Based on a thin film of titanium dioxide, it has a regime of operation with an approximately linear charge-resistance relationship.[5][6][7] These devices are being developed for application in nanoelectronic memories, computer logic, and neuromorphic computer architectures.

  • UC Davis Philosophy 102, Theory of Knowledge: Table of Contents for Lecture Notes – The subject of this course is what has come to be called “theory of knowledge” or “epistemology.” The two names are interchangeable in common use. (A similar pair of terms for philosophical disciplines is ‘theory of value’ (or ‘value theory’) and the little-used ‘axiology.’) Until the nineteenth century, there had been no special term to indicate the study of knowledge as such, even though knowledge had been studied from the very beginning of Western philosophy . The word “epistemology” was coined by James Ferrier in his 1856 book Institutes of Metaphysics. The root word ‘episteme’ in Greek means ‘knowledge,’ while the ‘-ology’ suffix signifies, roughly, ‘study of.’ Compare terms such as ‘biology’ (study of life), ‘geology’ (study of the earth), etc. Shortly after Ferrier, Eduard Zeller in 1862 introduced the German word ‘Erkenntnistheorie’ in Ueber Aufgabe und Bedeutung der Erkenntnistheorie. This word is translated into English as “theory of knowledge.”
  • Human or Cylon? Group testing on Battlestar Galactica (application/pdf Object) – Does statistics have a place though in the world of science fiction? Because science fiction writers try to merge the sci-fi world with the real world in a believable way, one might think that statistics could make a significant contribution to solving sci-fi problems.In the hit Sci Fi Network television show, the new Battlestar Galactica (a re-imagined version of the 1970’s show), there is an attempt to use science to solve a very important problem. Due to the excessive amount of time the proposed solution would take to complete, it is deemed impractical and never implemented. This paper shows how the problem could have been solved instead using a statistical technique called “group testing.” Scientists use this technique to solve many real-world problems, including the screening of blood donations for diseases. When applied to the problem on Battlestar Galactica, it will be shown that group testing could have a made dramatic difference to the course of the show
  • The Ninth Annual Year in Ideas – Magazine – NYTimes.com – Once again, The Times Magazine looks back on the past year from our favored perch: ideas. Like a magpie building its nest, we have hunted eclectically, though not without discrimination, for noteworthy notions of 2009 — the twigs and sticks and shiny paper scraps of human ingenuity, which, when collected and woven together, form a sort of cognitive shelter, in which the curious mind can incubate, hatch and feather. Unlike birds, we can also alphabetize. And so we hereby present, from A to Z, the most clever, important, silly and just plain weird innovations we carried back from all corners of the thinking world. To offer a nonalphabetical option for navigating the entries, this year we have attached tags to each item indicating subject matter.

  • How Did Economists Get It So Wrong? – NYTimes.com – What happened to the economics profession? And where does it go from here?

    As I see it, the economics profession went astray because economists, as a group, mistook beauty, clad in impressive-looking mathematics, for truth. Until the Great Depression, most economists clung to a vision of capitalism as a perfect or nearly perfect system. That vision wasn’t sustainable in the face of mass unemployment, but as memories of the Depression faded, economists fell back in love with the old, idealized vision of an economy in which rational individuals interact in perfect markets, this time gussied up with fancy equations.

  • Genius Is Overrated; Incremental Advances Underappreciated – A new book by W. Brian Arthur, a pioneer in the area of positive feedback in economics, argues that genius is overrated and technology drives its own innovations.
