A Bootstrap modal dialog is a Bootstrap component which creates a modal dialog window which floats over page-level content.
Here is an example of the basic usage of a Bootstrap modal dialog in HTML:
<div class="modal fade" tabindex="-1" role="dialog">
<div...
Modal dialog components can be instantiated via jQuery with the function $('#myModal').modal(options), where $('#myModal') is a top-level reference to the specific modal dialog and options is a Javascript object specifying the modal dialog's default attributes.
The options object allows for multipl...
ARFF files (Attribute-Relation File Format) are the most common format for data used in Weka. Each ARFF file must have a header describing what each data instance should be like. The attributes that can be used are as follows:
Numeric
Real or integer numbers.
Nominal
Nominal attributes m...
Depending on the version of Weka being used different methods for loading ARFF files should be utilised.
Weka <3.5.5
The following sample code shows how to load an ARFF file:
import weka.core.Instances;
import java.io.BufferedReader;
import java.io.FileReader;
...
BufferedReader reader = n...
Many databases can be used in Weka. Firstly, the DatabaseUtils.props file must be edited to match your database; specifically you must provide your database's name, location, port and correct driver.
jdbcDriver=org.gjt.mm.mysql.Driver
jdbcURL=jdbc:mysql://localhost:3306/my_database
Then the dat...
A literal inside a enumeration is a discrete type so we can use attribute Image to find out which literal it is as text form. Notice that this prints out the same word as in the code (but in upper case).
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
type Fruit is (Banana, Pear, Orang...
Instead of attribute Image and Ada.Text_IO.Put on enumeration literals we can only use the generic package Ada.Text_IO.Enumeration_IO to print out the literals.
with Ada.Text_IO; use Ada.Text_IO;
procedure Main is
type Fruit is (Banana, Pear, Orange, Melon);
package Fruit_IO is new Enume...
Attribute Image capitalizes all characters of enumeration literals. The function Case_Rule_For_Names applies upper case for the first character and makes the rest lower case.
with Ada.Text_IO; use Ada.Text_IO;
with Ada.Strings.Maps.Constants; use Ada.Strings.Maps.Constants;
with Ada.Strings.Fixed...
You can set the desired UI widget's stylesheet using any valid CSS. The example below will set a QLabel's text color a border around it.
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::Mai...
Simply specifying a file destination, echo will create, write, or append to a file.
<echo file=example.txt" append="false">
hello world
</echo>
To print the contents of a file, we can use loadfile to read a file into a local property, and then use echo to print the value of it.
<loadfile property="contents" srcFile="example.txt" />
<echo message="${contents}" />
requests uses specific environment variables automatically for proxy detection.
HTTP_PROXY will define the proxy URL to use for HTTP connections
HTTPS_PROXY will define the proxy URL to use for HTTPS connections
Once these environment variables are set, the Python code does not need to pass a...
The whole ES6 spec is not yet implemented in its entirety so you will only be able to use some of the new features. You can see a list of the current supported ES6 features at http://node.green/
Since NodeJS v6 there has been pretty good support. So if you using NodeJS v6 or above you can enjoy usi...

Annotations are means of attaching metadata to code. To declare an annotation, put the
annotation
modifier in front of a
class:
annotation class Strippable
Annotations can have meta-anotations:

The concept of timing is related more to the physics of flip flops than VHDL, but is an important concept that any designer using VHDL to create hardware should know.
When designing digital hardware, we are typically creating synchronous logic. This means our data travels from flip-flop to flip-flo...
