Elasticsearch provides data manipulation & data searching capabilities in almost real time. under this example, we have update, delete & batch processing operations.
Updating the same document. Suppose we have already indexed a
document on /car/external/1 . Then running the command for i...
You can print the array elements using the loop same as the Java enhanced loop, but you need to change keyword from : to in.
val asc = Array(5, { i -> (i * i).toString() })
for(s : String in asc){
println(s);
}
You can also change data type in for loop.
val asc = Array(5, { i -> (i...
As the header already says, the following list contains "interoperable signature types" which are more or less strictly defined. The PDF specification specifies a way to also include completely custom signing schemes. But let us assume we are in an interoperable situation. The the collecti...
In case of big data sets, the call of grepl("fox", test_sentences) does not perform well. Big data sets are e.g. crawled websites or million of Tweets, etc.
The first acceleration is the usage of the perl = TRUE option. Even faster is the option fixed = TRUE. A complete example would be:

This example shows how to make an interactive presentation transition with "real-world" physics similar to iOS's notifications screen.
To start with, we need a presenting view controller that the shade will appear over. This view controller will also act as our UIViewControllerTransitio...
The scatter function has two undocumented properties 'jitter' and 'jitterAmount' that allow to jitter the data on the x-axis only. This dates back to Matlab 7.1 (2005), and possibly earlier.
To enable this feature set the 'jitter' property to 'on' and set the 'jitterAmount' property to the desired ...
The old-school method for running another script from batch is to echo the script into another location, and then run it.
This method can be represented like this:
@echo off
rem VBS below
echo your vbs > TempVBS.vbs
echo other vbs>>TempVBS.vbs
rem End of VBS
cscript //nolog...
Processing provides method triangle() to draw a triangle. This code draws a white triangle on black background.
void setup() {
size(500, 500);
background(0);
fill(255);
noStroke();
}
void draw() {
triangle(250, 225, 225, 275, 275, 275);
}
Another convenient solution for cross compilation is the usage of gox: https://github.com/mitchellh/gox
Installation
The installation is done very easily by executing go get github.com/mitchellh/gox. The resulting executable gets placed at Go's binary directory, e.g. /golang/bin or ~/golang/bin. E...
In order to load data from a MongoDB database into an R dataframe, use the library MongoLite:
# Use MongoLite library:
#install.packages("mongolite")
library(jsonlite)
library(mongolite)
# Connect to the database and the desired collection as root:
db <- mongo(collection = &quo...

.DeleteFolder(FileSpec, Force (True/False))
.CreateFolder(Path)
.DeleteFile(FileSpec, Force (True/False))
The following example illustrates the Deletion and creation of a folder using the methods "DeleteFolder" and "CreateFolder".
Code:
Dim strFolderPath, ob...

.CopyFile(Source, Dest [,Overwrite (True/False)]
.CopyFolder(Source, Dest [,Overwrite (True/False)]
The following code illustrates the use of CopyFile method to copy a file to a new location. The same thing can be achieved for the folders by using the CopyFolder method.
Code:

strSourcePat...
Methods used:
.GetFolder(strPath) - Returns an object referring to the path
We can set an object reference to a folder using the getFolder method and perform different operations on them.
Code:
Dim strFolderPath, objFso, objFolder
strFolderPath = "C:\Users\GS\Desktop\LogsFolder"

As you would know, Hadoop can be run in the local environment in 3 different modes :
Local Mode
Pseudo Distributed Mode
Fully Distributed Mode (Cluster)
Typically you will be running your local hadoop setup in Pseudo Distributed Mode to leverage HDFS and Map Reduce(MR). However you cannot de...
As java provide two different commands to compile and run Java code. Same as Kotlin also provide you different commands.
javac to compile java files.
java to run java files.
Same as
kotlinc to compile kotlin files
kotlin to run kotlin files.
This example shows how to customize the UIDynamicItem protocol to map position changes of a view being dynamically animated to bounds changes to create a UIButton that expands and contracts in a elastic fashion.
To start we need to create a new protocol that implements UIDynamicItem but that also...
