40 Belief-Shaking Remarks From a Ruthless Nonconformist If there’s one thing Friedrich Nietzsche did well, it’s obliterate feel-good beliefs people have about themselves. He has been criticized for being a misanthrope, a subvert, a cynic and a pessimist, but I think these assessments are off the mark. I believe he only wanted human beings to be more honest with themselves. He did have a remarkable gift for aphorism — he once declared, “It is my ambition to say in ten sentences what others say in a whole book.” A hundred years after his death, Nietzsche retains his disturbing talent for turning a person’s worldview upside-down with one jarring remark. Even today his words remain controversial. Here are 40 unsympathetic statements from the man himself. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 38. 39. 40.

The Science of Word Recognition About fonts > ClearType The Science of Word Recognition or how I learned to stop worrying and love the bouma Kevin LarsonAdvanced Reading Technology, Microsoft CorporationJuly 2004 Introduction Evidence from the last 20 years of work in cognitive psychology indicate that we use the letters within a word to recognize a word. This paper is written from the perspective of a reading psychologist. The goal of this paper is to review the history of why psychologists moved from a word shape model of word recognition to a letter recognition model, and to help others to come to the same conclusion. I will start by describing three major categories of word recognition models: the word shape model, and serial and parallel models of letter recognition. Model #1: Word Shape The word recognition model that says words are recognized as complete units is the oldest model in the psychological literature, and is likely much older than the psychological literature. characters Model #2: Serial Letter Recognition

Chaos Theory for Beginners; An Introduction Life finds a way beauty of the unpredictable and display it in the most awesome patterns. Nature, when looked upon with the right kind of eyes, presents herself as one of the most fabulous works of art ever wrought. What is Chaos Theory? Chaos Theory is a mathematical sub-discipline that studies complex systems. Complex systems are systems that contain so much motion (so many elements that move) that computers are required to calculate all the various possibilities. But there is another reason that Chaos Theory was born so recently, and that is the Quantum Mechanical Revolution and how it ended the deterministic era! Up to the Quantum Mechanical Revolution people believed that things were directly caused by other things, that what went up had to come down, and that if only we could catch and tag every particle in the universe we could predict events from then on. How Chaos Theory was born and why. Hold that thought (7): The Uncertainty Principle prohibits accuracy. Attractors

How (and Why) to Partition Your Hard Drive | PCWorld Disk partitioning--separating one physical hard drive into multiple independent volumes--can relieve all sorts of computer-related headaches, and thanks to the Disk Management tool included with Windows 7 and Vista, you can perform the task without expensive third-party software. Here's how to use Disk Management to make the most of your hard drive. Why Partitioning Your Hard Drive Makes Sense Most PCs come from the factory with a single partition on their hard drive, meaning that it shows up as one drive in the Computer window (as C:, typically). But keeping your data, applications, and operating system on the same partition can be risky because, if something happens to the partition's index file (the file that tells your computer where the various pieces of your data are located), your computer won't be able to boot up off that drive--and even if you boot up with a recovery disc or external drive, you won't be able to access the rest of your data. How to Partition Your Hard Drive

¿Qué son las bases de datos? ¿Quieres ver la versión actualizada de este post? Entra a: NoSQL como el futuro de las bases de datos Una base de datos es un “almacén” que nos permite guardar grandes cantidades de información de forma organizada para que luego podamos encontrar y utilizar fácilmente. A continuación te presentamos una guía que te explicará el concepto y características de las bases de datos. El término de bases de datos fue escuchado por primera vez en 1963, en un simposio celebrado en California, USA. Desde el punto de vista informático, la base de datos es un sistema formado por un conjunto de datos almacenados en discos que permiten el acceso directo a ellos y un conjunto de programas que manipulen ese conjunto de datos. Cada base de datos se compone de una o más tablas que guarda un conjunto de datos. Definición de base de datos Características Entre las principales características de los sistemas de base de datos podemos mencionar: Sistema de Gestión de Base de Datos (SGBD) Consistencia de datos:

Fallacy List 1. FAULTY CAUSE: (post hoc ergo propter hoc) mistakes correlation or association for causation, by assuming that because one thing follows another it was caused by the other. example: A black cat crossed Babbs' path yesterday and, sure enough, she was involved in an automobile accident later that same afternoon. example: The introduction of sex education courses at the high school level has resulted in increased promiscuity among teens. 2. example: Muffin must be rich or have rich parents, because she belongs to ZXQ, and ZXQ is the richest sorority on campus. example: I'd like to hire you, but you're an ex-felon and statistics show that 80% of ex-felons recidivate. 3. example: All of those movie stars are really rude. 4. example: What's the big deal about the early pioneers killing a few Indians in order to settle the West? 5. 6. example: Either you favor a strong national defense, or you favor allowing other nations to dictate our foreign policy. example: It’s not TV. 7. 8. 9. 10. 11.

Want to work at Google? Answer these questions This article was taken from the March 2012 issue of Wired magazine.

It's famously tough getting through the Google interview process. But now we can reveal just how strenuous are the mental acrobatics demanded from prospective employees. 1. Those who were paying attention in rocket-science class will recall the formula for the energy of a projectile: E = mgh. 2. "Latency problem in South Africa" is an inside joke at Google. • The internet is running slowly in South Africa. • Google searches (only) are running slowly. The ping operation measures latency on the Internet. 3. The 2006 Emergency Evacuation Report Card of the American Highway Users Alliance gave Kansas City an A grade. • Make use of the fact that everyone wants to get out of the city as fast as possible. • Use school buses. • Divert petrol to the region's petrol stations. 4. 5.

The Document Which Was Formerly Called The MIT Guide to Lockpicking An interesting new lockpicking technique has been making its way around the internet. This technique uses 'bump keys' to open locks in a similar fashion to lockpicking guns but without requiring specialized hardware. You can read about bump keys in this document, and see a news report about them here. --- Presenting ---(drumroll please) I am told that the university which has its' name associated with this document would prefer not to. Fine. I will now no longer refer to it as The MIT Guide To Lockpicking or The MIT Lockpicking Guide. Which is too bad in a way. My original copy of this file was a text file zipped up with several GIF's. If you prefer, the entire thing is available as a PDF file or the original zipped postscript that the PDF was generated from. Nearly half of all the illustrations appear in chapter nine, so if that one takes a little while for your browser to fetch try to be patient. Otherwise, enjoy the file. - Akira - Dave Ferret Ted the Tool February 14, 1992 Distribution
