This example is was modeled after an example that I found on the internet. I can't find the link or I would give the author credit. I took the sample that I found and modified it to work for my application. Add the following references: System.Xaml, PresentationCore, PresentationFramework,...

One major aspect of process substitution is that it lets us avoid usage of a sub-shell when piping commands from the shell. This can be demonstrated with a simple example below. I have the following files in my current folder: $ find . -maxdepth 1 -type f -print foo bar zoo foobar foozoo barzoo ...

Within the CodeIgniter, there are two main directories to worry about: system and application. The system folder contains the core guts of CodeIgniter. The application folder will contain all of the code specific to your application, including models, controllers, views and other relevant libraries...

When you want for example enforce the use of the parameter Password if the parameter User is provided. (and vise versa) Function Do-Something { Param ( [Parameter(Mandatory=$true)] [String]$SomeThingToDo, [Parameter(ParameterSetName="Credentials", man...

Here are the steps to generate test skeleton for existing code: Open Eclipse, and choose the project you want to create test cases for In the Package Explorer, select the java class you want to generate the Junit test for Go to File -> New -> Junit Test Cases Change the Source folder to ...

ZeroR is a simple classifier. It doesn't operate per instance instead it operates on general distribution of the classes. It selects the class with the largest a priori probability. It is not a good classifier in the sense that it doesn't use any information in the candidate, but it is often used as...

In order to build a good classifier we will often need to get an idea of how the data is structered in feature space. Weka offers a visualisation module that can help. Some dimensions already seperate the classes quite well. Petal-width orders the concept quite neatly, when compared to petal-widt...

Linux distribution with features required to run Kodi.

Data mining is a wide topic, and the term is (unfortunately) very liberally thrown at any topic that involves data processing. Because of this this "documentation" should never have been created in the first place, because it overlaps with other topcis too much, and everything is better di...

When dealing with large configuration sets of value, it might become quite unhandy to load them one buy one. Option model which comes with asp.net offers a convenient way to map a section to a dotnet poco: For instance, one might hydrate StorageOptions directly from a configuration section b addin...

public String getHighlightedText(final QueryResponse queryResponse, final String fieldName, final String docId) { String highlightedText = ""; Map<String, Map<String, List<String>>> highlights = queryResponse.getHighlighting(); if (highlights!=null &&am...

This example creates a simple window with a button and a line-edit in a layout. It also shows how to connect a signal to a slot, so that clicking the button adds some text to the line-edit. import sys from PyQt5.QtWidgets import QApplication, QWidget if __name__ == '__main__': app ...

var indexController = myApp.controller("indexController", function ($scope) { // controller logic goes here $scope.message = "Hello Hacking World" });

In T4 code-generation strategy used by Entity Framework 5 and higher, data annotation attributes are not included by default. To include data annotations on top of certain property every model regeneration, open template file included with EDMX (with .tt extension) then add a using statement under U...

Without splatting it is very cumbersome to try and pass values down through the call stack. But if you combine splatting with the power of the @PSBoundParameters then you can pass the top level parameter collection down through the layers. Function Outer-Method { Param ( [string...

SELECT * FROM MY_TABLE

map() is a built-in function, which means that it is available everywhere without the need to use an 'import' statement. It is available everywhere just like print() If you look at Example 5 you will see that I had to use an import statement before I could use pretty print (import pprint). Thus ppr...
