Human-Centered Computing: Toward a Human Revolution

  • Interactive evolutionary computation, an interesting technique first
    developed in the early 1990s and more recently known as human
    computation
    , (7) also puts the human at the center, but in a different
    way. In traditional computation, a human provides a formalized problem
    description to a computer and receives a solution to interpret. In human
    computation, the roles are reversed: The computer asks a person or a large
    number of people to solve a problem, then collects, interprets, and integrates
    their solutions. In other words, the computer "asks" the human to do
    the work it cannot do. This is done as a way to overcome technical
    difficulties: Instead of trying to get computers to solve problems that are too
    complex, use human beings.



    In human computation, the human is helping the computer solve difficult
    problems, but in HCC, the computer helps humans maximize their abilities
    regardless of the situation—the human need not be in front of a computer
    performing a computing task when dealing with the computer.



    Although HCC and human-based computation approach computing from two
    different perspectives, they both try to maximize the synergy between human
    abilities and computing resources. Work in human computation can therefore be
    of significant importance to HCC. On one hand, data collected through human
    computation systems can be valuable for developing machine-learning models. On
    the other hand, it can help us better understand human behavior and abilities,
    again of direct use in HCC algorithm development and system design.

  • If the replacement is a function, not a string, the arguments passed to the function are any captures that are made. If the function returns a string, the value returned is substituted back into the string.

  • Notice then that the only result which does not output is "Zero". If an if statement evaluates as "zero" then it is false. If it evaluates to any non zero value it will evaluate as true. We can take advantage of this to get more details from our function.

    was embarrassed. "But I don't understand anything yet. I don't know how
    to help. I'd just be in the way," I protested.

    remember his answer very clearly "That doesn't matter," he said.
    "just go over there and hang around. Do anything anybody asks you to
    do. Sooner or later someone will see that you're there, and they'll ask you
    to hold a screwdriver. Get your hands dirty Pretty soon you'll know how things
    are constructed. Once they have seen that you're around a lot, they may ask
    you to help test the apparatus.

Maven - Maven Getting Started Guide

  • pom.xml contains the Project Object Model (POM) for this project. The POM is the basic unit of work in Maven. This is important to remember because Maven is inherently project-centric in that everything revolves around the notion of a project. In short, the POM contains every important piece of information about your project and is essentially one-stop-shopping for finding anything related to your project
  • where ${basedir} represents the directory containing pom.xml).

Maven - Introduction to the POM

  • he Super POM is Maven's default POM. All POMs extend the Super POM unless explicitly set, meaning the configuration specified in the Super POM is inherited by the POMs you created for your projects. The snippet below is the Super POM for Maven 2.0.x.
  • Alternatively, if we want the groupId and / or the version of your modules to be the same as their parents, you can remove the groupId and / or the version identity of your module in its POM.
  • 1 more annotations...

Maven - Guide to Configuring Maven

  • You can specify your user configuration in ${user.home}/.m2/settings.xml. A full reference to the configuration file is available. This section will show how to make some common configurations. Note that the file is not required - defaults will be used if it is not found.
