      Devhelp is a developer tool for browsing and searching API documentation.
      It provides an easy way to navigate through libraries and to search by
      function, struct, or macro.
    
      
      The documentation must be installed locally, so an internet connection is
      not needed to use Devhelp.
    
      
      Devhelp works natively with GTK-Doc, so the GTK and GNOME libraries are
      well supported. But other development platforms can be supported as well,
      as long as the API documentation is available in HTML and a *.devhelp2
      index file is generated.
    
      
      Devhelp integrates with other applications such as Glade, Builder or
      Anjuta, and plugins are available for different text editors (gedit, Vim,
      Emacs, Geany, …).

        CraftOS-PC is a fantasy terminal that allows you to write and run 
        programs inside an '80s-style text console.
    
      
        CraftOS-PC emulates the popular Minecraft mod "ComputerCraft", which 
        adds programmable computers to Minecraft using the Lua programming 
        language. CraftOS-PC takes this experience outside Minecraft to allow 
        you to run the same programs anywhere you go.
    
      
        CraftOS-PC provides a set of functions (called APIs) that make it super 
        easy to do simple tasks such as write text to the screen, read files, 
        and more. The simplicity of these functions makes CraftOS-PC great for 
        new programmers, but their power makes it possible to write all sorts of
        complex programs with less code.
    
      
        If you aren't ready to write programs yet, there's already a large 
        number of programs for ComputerCraft that will work in CraftOS-PC, 
        ranging from simple games to whole graphical operating systems. These 
        can be downloaded through the built-in Pastebin and GitHub Gist clients.

To allow for identification, resistors are usually marked with colored bands. Often refered to as color codes, these markings are indicative of their resistance, tolerance and temperature coefficient. gResistor helps you translate resistor color codes into a readable value. All you have to do is watch the colors on the resistor and then enter them in the program. As you enter colours you'll see that the resistor value is changing accordingly.
