Import and Export Bulk Data by Using the bcp Utility (SQL Server) This topic provides an overview for using the bcp utility to export data from anywhere in a SQL Server database where a SELECT statement works, including partitioned views. The bcp utility (Bcp.exe) is a command-line tool that uses the Bulk Copy Program (BCP) API. The bcp utility performs the following tasks: Bulk exports data from a SQL Server table into a data file. Bulk exports data from a query. The bcp utility is accessed by the bcp command. The bcp utility can export data from a SQL Server table to a data file for use in other programs. The bcp command provides switches that you use to specify the data type of the data file and other information. For a description of the bcp command syntax, see bcp Utility.

Lexical Distance Among the Languages of Europe « Etymologikon™ Posted by Teresa Elms on 4 March 2008 This chart shows the lexical distance — that is, the degree of overall vocabulary divergence — among the major languages of Europe. The size of each circle represents the number of speakers for that language. Circles of the same color belong to the same language group. All the groups except for Finno-Ugric (in yellow) are in turn members of the Indo-European language family. English is a member of the Germanic group (blue) within the Indo-European family. So why is English still considered a Germanic language? The original research data for the chart comes from K. Like this: Like Loading... Lazy evaluation The benefits of lazy evaluation include: Performance increases by avoiding needless calculations, and error conditions in evaluating compound expressionsThe ability to construct potentially infinite data structuresThe ability to define control flow (structures) as abstractions instead of primitives Lazy evaluation is often combined with memoization, as described in Jon Bentley's Writing Efficient Programs.[4] After a function's value is computed for that parameter or set of parameters, the result is stored in a lookup table that is indexed by the values of those parameters; the next time the function is called, the table is consulted to determine whether the result for that combination of parameter values is already available. If so, the stored result is simply returned. The opposite of lazy evaluation is eager evaluation, sometimes known as strict evaluation. History[edit] Applications[edit] Delayed evaluation is used particularly in functional programming languages. if a then b else c

Sophisme Un article de Wikipédia, l'encyclopédie libre. Un sophisme est une argumentation à la logique fallacieuse. C'est un raisonnement qui cherche à paraître rigoureux mais qui n'est en réalité pas valide au sens de la logique (quand bien même sa conclusion serait pourtant la « vraie »). À l'inverse du paralogisme, qui est une erreur dans un raisonnement, le sophisme est fallacieux : il est prononcé avec l'intention de tromper l'auditoire afin, par exemple, de prendre l'avantage dans une discussion. Origines du mot[modifier | modifier le code] Le mot sophisme dérive du latin sŏphisma, lui-même issu du grec σόφισμα (sóphisma) : « habileté », « invention ingénieuse », « raisonnement trompeur ». Exemples[modifier | modifier le code] Dans l'emmental, il y a des trous. Plus il y a d'emmental, plus il y a de trous. Plus il y a de trous, moins il y a d'emmental. Donc plus il y a d'emmental, moins il y a d'emmental [figure de sens, syllogisme]. Tout ce qui est rare est cher, Un cheval bon marché est rare,

CARE — Comprehensive Archiver for Reproducible Execution Fuzzy-trace theory Fuzzy-trace theory (FTT) is a theory of cognition originally proposed by Valerie F. Reyna and Charles Brainerd[1] that draws upon dual-trace[clarification needed] conceptions to predict and explain cognitive phenomena, particularly in memory and reasoning. The theory has been used in areas such as cognitive psychology, human development, and social psychology to explain, for instance, false memory[2] and its development,[3] probability judgments,[4] medical decision making,[5][6][7][8] risk perception and estimation, and biases and fallacies in decision making.[9][10] History[edit] In 1999, a similar approach was applied to human vision.[17] It suggested that human vision has two types of processing: one that aggregates local spatial receptive fields, and one that parses the local receptive field. Memory[edit] FTT posits two types of memory processes (verbatim and gist) and, therefore, it is often referred to as a dual process theory of memory. Principles[edit] Process independence[edit]

Amelia Earhart: Breaking Barriers of Earth and Sky | Charles F. Bolden, Jr. Editor's Note: This post is part of a series produced by HuffPost's Girls In STEM Mentorship Program. Join the community as we discuss issues affecting women in science, technology, engineering and math. If Amelia Earhart were alive today, there is a good chance she would be a NASA astronaut. I say that, not only because of Earhart's noted passion for breaking barriers of possibility in flight, but also for her determination to break barriers of exclusion here on Earth. As we celebrate Amelia Earhart Day in recognition of one her greatest accomplishments - the first person to fly solo over the Pacific on January 11, 1935 -- I want to salute the contributions that both she and the field of aeronautics have made to our nation. While NASA was not officially born until 1958, twenty-one years after Earhart disappeared during her 1937 attempt to become the first woman to fly around the world, she had a connection to the agency.

The Gambas Project: It's Like Visual Basic On Linux Gambas is an open-source development environment based on a Basic interpreter and with support for object extensions. It's been compared to Visual Basic, but Gambas supports Linux and is GPLv2 software. A developer behind Gambas is a Phoronix fan and recently pointed out his project that goes by the tag line "Gambas Almost Means BASIC!" The premise behind the project is to have a graphical development environment based on BASIC that's almost as eays to use as Microsoft's Visual Basic. However, Gambas isn't trying to achieve any Visual Basic re-implementation or compatibility: it's just comparing itself to VB in terms of ease of use, etc. The developer behind Gambas was inspired by Visual Basic's ease-of-use, the development environment, and the low barrier of entry to getting involved with VB application development. The Gambas project has been in development for several years now by Benoît Minisini.

Three arguments about climate change that should never be used Stop me if you've heard any of these before: "The warming is just part of a natural cycle." "We've been warming up since the last ice age." "To think humanity can influence the climate is pure arrogance." If you haven't heard these arguments before, it's clearly because you've never read any of the discussions attached to our climate articles. “The warming is just part of a natural cycle” Is this a natural cycle? The other reason that this is a nonsensical argument is that natural cycles aren't some sort of magic—like anthropogenic factors, they influence the climate for physical reasons. “We’ve been warming up since the last ice age” OK, so maybe there's something very subtle and longer-term going on around here. This warming influence peaked over 5,000 years ago. If you look at materials that capture indications of past temperatures, that's exactly what you see. “To think humanity can influence the climate is pure arrogance” There is really nothing sensible about any of these arguments.

Morhaus/dispatch-proxy The Nature of Code “To play life you must have a fairly large checkerboard and a plentiful supply of flat counters of two colors. It is possible to work with pencil and graph paper but it is much easier, particularly for beginners, to use counters and a board.” — Martin Gardner, Scientific American (October 1970) In this chapter, we’re going to take a break from talking about vectors and motion. In fact, the rest of the book will mostly focus on systems and algorithms (albeit ones that we can, should, and will apply to moving bodies). In the previous chapter, we encountered our first Processing example of a complex system: flocking. 7.1 What Is a Cellular Automaton? First, let’s get one thing straight. In Chapters 1 through 6, our objects (mover, particle, vehicle, boid) generally existed in only one “state.” A cellular automaton is a model of a system of “cell” objects with the following characteristics. The cells live on a grid. Figure 7.1 7.2 Elementary Cellular Automata 1) Grid. Figure 7.2 2) States.
