As rule of thumb, one would want his RDD to have as many partitions as the product of the number of executors by the number of used cores by 3 (or maybe 4). Of course, that's a heuristic and it really depends on your application, dataset and cluster configuration.
Example:
In [1]: data = sc.textF...
The invoice number is used to verify the sale for publishers. Many publishers of paid asset or plugin ask for the invoice number upon request of support. The invoice number is also used as a license key to activate some asset or plugin.
The invoice number can be found in two place:

The below example widget demonstrates how to format individual cells of a TreeView column conditionally, depending on value of the field in the particular cell. If value of field is negative, then it'll be displayed in red color and minus symbol will be hidden, otherwise it'll be displayed in normal...
Just add this function to your functions.php. It will remove the version from all enqueued js and css files.
function remove_cssjs_ver( $src ) {
if( strpos( $src, '?ver=' ) )
$src = remove_query_arg( 'ver', $src );
return $src;
}
add_filter( 'style_loader_src', 'remove_cssjs_ver', 9...
The next example can be used to determine whether a enumeration has the FlagsAttribute specified. The methodology used is based on Reflection.
This example will give a True result:
Dim enu As [Enum] = New FileAttributes()
Dim hasFlags As Boolean = enu.GetType().GetCustomAttributes(GetType(FlagsAt...
The next code illustrates how to find the nearest value of a Enum.
First we define this Enum that will serve to specify search criteria (search direction)
Public Enum EnumFindDirection As Integer
Nearest = 0
Less = 1
LessOrEqual = 2
Greater = 3
GreaterOrEqual = 4
End Enum...
The XML document, I will be using throughout the examples is -
<a>
<b>test-value</b>
<d>fragment-d</d>
<c-root>
<d>fragment-d</d>
<e>fragment-e</e>
</c-root>
</a>
The following queries ...
xdmp:estimate(cts:search(fn:doc(), cts:element-value-query(xs:QName("d"), "fragment-d")))
xdmp:estimate can not be used on XPaths unlike fn:count is used in previous example
xdmp:estimate actually gives the number of matching fragments
To add Numpy to the bundle, modify the setup.py with include_dirs keyword and necessary import the numpy in the wrapper Python script to notify Pyinstaller.
program.pyx:
import numpy as np
cimport numpy as np
def do_stuff():
print("Hello World!")
cdef int n
n = 2

Assume the following enum:
enum Operation {
Multiply(left : Int, right : Int);
}
Enum matching can be performed as follows:
var result = switch(Multiply(1, 3)) {
case Multiply(_, 0):
0;
case Multiply(0, _):
0;
case Multiply(l, r):
l * r;
}

The bulleted list control creates bulleted lists or numbered lists. These controls contain a collection of ListItem objects that could be referred to through the Items property of the control.
Basic syntax of a bulleted list:
<asp:BulletedList ID="BulletedList1" runat="server&quo...
Often you will want to have an input box that takes numbers only. Again by deriving from the standard controls this is easily achieved, for example:
using System;
using System.Windows.Forms;
using System.Globalization;

public class SONumberBox : SO...
OpenCL is low level api so it must be implemented in "C space" first. For that, one needs to download header files from Khronos' site. My hardware is AMD and capable of version 1.2, downloading

cl_ext.h
cl_egl.h
cl_dx9_media_sharing.h

This example shows how to find number of days between two dates. A date is specified by year/month/day of month, and additionally hour/minute/second.
Program calculates number of days in years since 2000.

Mocking an interface that inherits from IEnumerable to return canned data is quite straightforward. Assuming the following classes:
public class DataClass
{
public int Id { get; set; }
}
public interface IEnumerableClass : IEnumerable<DataClass>

The following approach can ...
NumericUpDown is control that looks like TextBox. This control allow user to display/select number from a range. Up and Down arrows are updating the textbox value.
Control look like;
In Form_Load range can be set.
private void Form3_Load(object sender, EventArgs e)
{

This example shows how to use fast enumeration in order to traverse through an NSArray. With this way you can also track current object's index while traversing.
Suppose you have an array,
NSArray *weekDays = @[@"Monday", @"Tuesday", @"Wednesday", @"Thursday"...
