Since Groovy 1.8 a convenient memoize() method is added on closures:
// normal closure
def sum = { int x, int y ->
println "sum ${x} + ${y}"
return x + y
}
sum(3, 4)
sum(3, 4)
// prints
// sum 3 + 4
// sum 3 + 4
// memoized closure
def sumMemoize = sum.memoize()

Auditing is an Alfresco feature that allows the user to trace and log some specific events during ECM platform usage.

Here is our function to create a simple ajax call written in vanilla javascript (not es2015):
function ajax(url, callback) {
var xhr;
if(typeof XMLHttpRequest !== 'undefined') xhr = new XMLHttpRequest();
else {
var versions = ["MSXML2.XmlHttp.5.0",

import requests
import json
params = {'id': 'blahblah', 'output': 'json'} # You could ...
To make an app more cohesive, we often need to keep user's personal settings and preferences consistent across multiple devices that have been logged in with one Microsoft account.

By using the Grid.RowSpan and Grid.ColumnSpan attached properties, children of a Grid can span multiple rows or columns.
In the following example the second TextBlock will span the second and third column of the Grid.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/&...
The row heigths or column widths of multiple Grids can be synchronized by setting a common SharedSizeGroup on the rows or columns to synchronize. Then a parent control somewhere up in the tree above the Grids needs to have the attached property Grid.IsSharedSizeScope set to True.
<StackPanel Gri...

Xamarins built in gesture recognizers provide only very basic touch handling. E.g. there is no way to get the position of a touching finger.
MR.Gestures is a component which adds 14 different touch handling events. The position of the touching fingers is part of the EventArgs passed to all MR.Gestu...
